CELLECTAR BIOSCIENCES : Management’s Discussion and Analysis of Financial Condition and Results of Operations (form 10-Q) – marketscreener.com

By daniellenierenberg

Overview

We are a clinical stage biopharmaceutical company focused on the discovery,development and commercialization of drugs for the treatment of cancer. We aredeveloping proprietary drugs independently and through research and developmentcollaborations. Our core objective is to leverage our proprietary phospholipiddrug conjugate (PDC) delivery platform to develop PDCs that are designed tospecifically target cancer cells and deliver improved efficacy and better safetyas a result of fewer off-target effects. Our PDC platform possesses thepotential for the discovery and development of the next generation ofcancer-targeting treatments, and we plan to develop PDCs both independently andthrough research and development collaborations. The COVID-19 pandemic hascreated uncertainties in the expected timelines for clinical stagebiopharmaceutical companies such as us, and because of such uncertainties, it isdifficult for us to accurately predict expected outcomes at this time. We havenot yet experienced any significant impacts as a result of the pandemic and havecontinued to enroll patients in our clinical trials. However, COVID-19 mayimpact our future ability to recruit patients for clinical trials, obtainadequate supply of CLR 131 and obtain additional financing.

Our lead PDC therapeutic, CLR 131 is a small-molecule PDC designed to providetargeted delivery of iodine-131 directly to cancer cells, while limitingexposure to healthy cells. We believe this profile differentiates CLR 131 frommany traditional on-market treatment options. CLR 131 is the company's leadproduct candidate and is currently being evaluated in a Phase 2 study inrelapsed/refractory (r/r) B-cell malignancies, including multiple myeloma (MM),chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL),lymphoplasmacytic lymphoma/Waldenstrom's macroglobulinemia (LPL/WM), marginalzone lymphoma (MZL), mantle cell lymphoma (MCL), and diffuse large B-celllymphoma (DLBCL).CLR 131 is also being evaluated in a Phase 1 dose escalationstudy in pediatric solid tumors and lymphoma. The U.S. Food and DrugAdministration ("FDA") granted CLR 131 Fast Track Designation for both r/r MMand r/r DLBCL and Orphan Drug Designation (ODD) of MM, LPL/WM, neuroblastoma,rhabdomyosarcoma, Ewing's sarcoma and osteosarcoma. CLR 131 was also grantedRare Pediatric Disease Designation (RPDD) for the treatment of neuroblastoma,rhabdomyosarcoma, Ewing's sarcoma and osteosarcoma. Most recently, the EuropeanCommission granted an ODD for r/r MM.

Our product pipeline also includes one preclinical PDC chemotherapeutic program(CLR 1900) and several partnered PDC assets. The CLR 1900 Series is beingtargeted for solid tumors with a payload that inhibits mitosis (cell division) avalidated pathway for treating cancers.

We have leveraged our PDC platform to establish four collaborations featuringfive unique payloads and mechanisms of action. Through research and developmentcollaborations, our strategy is to generate near-term capital, supplementinternal resources, gain access to novel molecules or payloads, accelerateproduct candidate development and broaden our proprietary and partnered productpipelines.

Our PDC platform provides selective delivery of a diverse range of oncologicpayloads to cancerous cells, whether a hematologic cancer or solid tumor, aprimary tumor, or a metastatic tumor and cancer stem cells. The PDC platform'smechanism of entry does not rely upon specific cell surface epitopes or antigensas are required by other targeted delivery platforms. Our PDC platform takesadvantage of a metabolic pathway utilized by all tumor cell types in all stagesof the tumor cycle. Tumor cells modify specific regions on the cell surface as aresult of the utilization of this metabolic pathway. Our PDCs bind to theseregions and directly enter the intracellular compartment. This mechanism allowsthe PDC molecules to accumulate over time, which enhances drug efficacy, and toavoid the specialized highly acidic cellular compartment known as lysosomes,which allows a PDC to deliver molecules that previously could not be delivered.Additionally, molecules targeting specific cell surface epitopes face challengesin completely eliminating a tumor because the targeted antigens are limited inthe total number on the cell surface, have longer cycling time frominternalization to being present on the cell surface again and available forbinding and are not present on all of the tumor cells in any cancer. This meansa subpopulation of tumor cells always exist that cannot be targeted by therapiestargeting specific surface epitopes. In addition to the benefits provided by themechanism of entry, PDCs offer the ability to conjugate payload molecules innumerous ways, thereby increasing the types of molecules selectively deliveredvia the PDC.

The PDC platform features include the capacity to link with almost any molecule,provide a significant increase in targeted oncologic payload delivery and theability to target all types of tumor cells. As a result, we believe that we cangenerate PDCs to treat a broad range of cancers with the potential to improvethe therapeutic index of oncologic drug payloads, enhance or maintain efficacywhile also reducing adverse events by minimizing drug delivery to healthy cells,and increasing delivery to cancerous cells and cancer stem cells.

We employ a drug discovery and development approach that allows us toefficiently design, research and advance drug candidates. Our iterative processallows us to rapidly and systematically produce multiple generations ofincrementally improved targeted drug candidates.

In June 2020, the European Medicines Agency (EMA) granted us Small andMedium-Sized Enterprise status by the EMA's Micro, Small and Medium-sizedEnterprise office. SME status allows us to participate in significant financialincentives that include a 90% to 100% EMA fee reduction for scientific advice,clinical study protocol design, endpoints and statistical considerations,quality inspections of facilities and fee waivers for selective EMA pre andpost-authorization regulatory filings, including orphan drug and PRIMEdesignations. We are also eligible to obtain EMA certification of quality andmanufacturing data prior to review of clinical data. Other financial incentivesinclude EMA-provided translational services of all regulatory documents requiredfor market authorization, further reducing the financial burden of the marketauthorization process.

A description of our PDC product candidates follows:

Our lead PDC therapeutic, CLR 131 is a small-molecule, PDC designed to providetargeted delivery of iodine-131 directly to cancer cells, while limitingexposure to healthy cells. We believe this profile differentiates CLR 131 frommany traditional on-market treatments and treatments in development. CLR 131 iscurrently being evaluated in a Phase 2 study in r/r B-cell lymphomas, and twoPhase 1 dose-escalating clinical studies, one in r/r MM and one in r/r pediatricsolid tumors and lymphoma. The initial Investigational New Drug (IND)application was accepted by the FDA in March 2014 with multiple INDs submittedsince that time. Initiated in March 2017, the primary goal of the Phase 2 studyis to assess the compound's efficacy in a broad range of hematologic cancers.The Phase 1 study is designed to assess the compound's safety and tolerabilityin patients with r/r MM (to determine maximum tolerated dose) and was initiatedin April 2015. The FDA previously accepted our IND application for a Phase 1open-label, dose escalating study to evaluate the safety and tolerability of asingle intravenous administration of CLR 131 in up to 30 children andadolescents with cancers including neuroblastoma, sarcomas, lymphomas (includingHodgkin's lymphoma) and malignant brain tumors. This study was initiated duringthe first quarter of 2019. These cancer types were selected for clinical,regulatory and commercial rationales, including the radiosensitive nature andcontinued unmet medical need in the r/r setting, and the rare diseasedeterminations made by the FDA based upon the current definition within theOrphan Drug Act.

In December 2014, the FDA granted ODD for CLR 131 for the treatment of MM.Multiple myeloma is an incurable cancer of the plasma cells and is the secondmost common form of hematologic cancers. In 2018, the FDA granted ODD and RPDDfor CLR 131 for the treatment of neuroblastoma, rhabdomyosarcoma, Ewing'ssarcoma and osteosarcoma. The FDA may award priority review vouchers to sponsorsof rare pediatric disease products that meet its specified criteria. The keycriteria to receiving a priority review voucher is that the disease beingtreated is life-threatening and that it primarily effects individuals under theage of 18. Under this program, a sponsor who receives an approval for a drug orbiologic for a rare pediatric disease can receive a priority review voucher thatcan be redeemed to receive a priority review of a subsequent marketingapplication for a different product. Additionally, these priority reviewvouchers can be exchanged or sold to other companies for them to use thevoucher. In May 2019, the FDA granted Fast Track designation for CLR 131 for thetreatment of multiple myeloma in July 2019 for the treatment of DLBCL, inSeptember, CLR 131 received Orphan Drug Designation from the European Union forMultiple Myeloma, and in January 2020, the FDA granted Orphan Drug Designationfor CLR 131 in lymphoplasmacytic lymphoma (LPL).

Phase 2 Study in Patients with r/r select B-cell Malignancies

In February 2020, we announced positive data from our Phase 2 CLOVER-1 study inpatients with relapsed/refractory B-cell lymphomas. Relapsed/Refractory MM andnon-Hodgkin lymphoma (NHL) patients were treated with three different doses(<50mCi, ~50mCi and ~75mCi total body dose (TBD). The <50mCi total body dose wasa deliberately planned sub-therapeutic dose. CLR 131 achieved the primaryendpoint for the study. Patients with r/r MM who received the highest dose ofCLR 131 showed a 42.8% overall response rate (ORR). Those who received ~50mCiTBD had a 26.3% ORR with a combined rate of 34.5% ORR (n=33) while maintaining awell-tolerated safety profile. Patients in the studies were elderly with amedian age of 70, and heavily pre-treated, with a median of five prior lines oftreatment (range: 3 to 17), which included immunomodulatory drugs, proteasomeinhibitors and CD38 antibodies for the majority of patients. Additionally, amajority of the patients (53%) were quad refractory or greater and 44% of alltreated multiple myeloma patients were triple class refractory. 100% of allevaluable patients (n=43) achieved clinical benefit (primary outcome measure) asdefined by having stable disease or better. 85.7% of multiple myeloma patientsreceiving the higher total body dose levels of CLR 131 experienced tumorreduction. The 75mCi TBD demonstrated positive activity in both high-riskpatients and triple class refractory patients with a 50% and 33% ORR,respectively.

Patients with r/r NHL who received ~50mCi TBD and the ~75mCi TBD had a 42% and43% ORR, respectively and a combined rate of 42%. These patients were alsoheavily pre-treated, having a median of three prior lines of treatment (range, 1to 9) with the majority of patients being refractory to rituximab and/oribrutinib. The patients had a median age of 70 with a range of 51 to 86. Allpatients had bone marrow involvement with an average of 23%. In addition tothese findings, subtype assessments were completed in the r/r B-cell NHLpatients. Patients with DLBCL demonstrated a 30% ORR with one patient achievinga complete response (CR), which continues at nearly 24 months post-treatment.The ORR for CLL/SLL/MZL patients was 33%. Current data from our Phase 2 CLOVER-1clinical study show that four LPL/WM patients demonstrated 100% ORR with onepatient achieving a CR which continues at nearly 27 months post-treatment. Thismay represent an important improvement in the treatment of relapsed/refractoryLPL/WM as we believe no approved or late-stage development treatments forsecond- and third-line patients have reported a CR. LPL/WM is a rare, indolentand incurable form of NHL that is composed of a patient population in need ofnew and better treatment options.

The most frequently reported adverse events in r/r MM patients were cytopenias,which followed a predictable course and timeline. The frequency of adverseevents have not increased as doses were increased and the profile of cytopeniasremains consistent. Importantly, these cytopenias have had a predictable patternto initiation, nadir and recovery and are treatable. The most common grade ?3events at the highest dose (75mCi TBD) were hematologic toxicities includingthrombocytopenia (65%), neutropenia (41%), leukopenia (30%), anemia (24%) andlymphopenia (35%). No patients experienced cardiotoxicities, neurologicaltoxicities, infusion site reactions, peripheral neuropathy, allergic reactions,cytokine release syndrome, keratopathy, renal toxicities, or changes in liverenzymes. The safety and tolerability profile in patients with r/r NHL wassimilar to r/r MM patients except for fewer cytopenias of any grade. Based uponCLR 131 being well tolerated across all dose groups and the observed responserate, especially in difficult to treat patients such as high risk and tripleclass refractory or penta-refractory, and corroborating data showing thepotential to further improve upon current ORRs and durability of thoseresponses, the study has been expanded to test a two-cycle dosing optimizationregimen of CLR 131.

In July 2016, we were awarded a $2,000,000National Cancer Institute (NCI)Fast-Track Small Business Innovation Research grant to further advance theclinical development of CLR 131. The funds are supporting the Phase 2 studyinitiated in March 2017 to define the clinical benefits of CLR 131 in r/r MM andother niche hematologic malignancies with unmet clinical need. These nichehematologic malignancies include Chronic Lymphocytic Leukemia, Small LymphocyticLymphoma, Marginal Zone Lymphoma, Lymphoplasmacytic Lymphoma and DLBCL. Thestudy is being conducted in approximately 10 U.S. cancer centers in patientswith orphan-designated relapse or refractory hematologic cancers. The study'sprimary endpoint is clinical benefit response (CBR), with additional endpointsof ORR, progression free survival (PFS,) median Overall Survival (mOS) and othermarkers of efficacy following a single 25.0 mCi/m2 dose of CLR 131, with theoption for a second 25.0 mCi/m2dose approximately 75-180 days later. Based onthe performance results from Cohort 5 of our Phase 1 study in patients with r/rMM, reviewed below, we have modified the dosing regimen of this study to afractionated dose of 15.625 mCi/m2 administered on day 1 and day 8.

In May 2020, we announced that the FDA granted Fast Track Designation for CLR131 in LPL/WM in patients having received two prior treatment regimens or more.

Phase 1 Study in Patients with r/r Multiple Myeloma

In February 2020, we announced the successful completion of our Phase 1 doseescalation study. Data from the study demonstrated that CLR 131 was safe andtolerated at total body dose of approximately 90mCi in r/r MM. The Phase 1multicenter, open-label, dose-escalation study was designed to evaluate thesafety and tolerability of CLR 131 administered as a 30-minute I.V. infusion,either as a single bolus dose or as two fractionated doses. The r/r multiplemyeloma patients in this study received single cycle doses ranging fromapproximately 20mCi to 90mCi total body dose. To date, an independent DataMonitoring Committee determined that all doses have been safe and well-toleratedby patients.

CLR 131 in combination with dexamethasone is currently under investigation inadult patients with r/r MM. Patients must have been refractory to or relapsedfrom at least one proteasome inhibitor and at least one immunomodulatory agent.The clinical study is a standard three-plus-three dose escalation safety studyto determine the maximum tolerable dose. Multiple myeloma is an incurable cancerof the plasma cells and is the second most common form of hematologic cancers.Secondary objectives include the evaluation of therapeutic activity by assessingsurrogate efficacy markers, which include M protein, free light chain (FLC), PFSand OS. All patients have been heavily pretreated with an average of five priorlines of therapy. CLR 131 was deemed by an Independent Data Monitoring Committee(IDMC) to be safe and tolerable up to its planned maximum single, bolus dose of31.25 mCi/m2. The four single dose cohorts examined were: 12.5 mCi/m2(~25mCiTBD), 18.75 mCi/m2 (~37.5mCi TBD), 25 mCi/m2(~50mCi TBD), and 31.25mCi/m2(~62.5mCi TBD), all in combination with low dose dexamethasone (40 mgweekly). Of the five patients in the first cohort, four achieved stable diseaseand one patient progressed at Day 15 after administration and was taken off thestudy. Of the five patients admitted to the second cohort, all five achievedstable disease however one patient progressed at Day 41 after administration andwas taken off the study. Four patients were enrolled to the third cohort and allachieved stable disease. In September 2017, we announced results for cohort 4,showing that a single infusion up to 30-minutes of 31.25mCi/m2 of CLR 131 wassafe and tolerated by the three patients in the cohort. Additionally, all threepatients experienced CBR with one patient achieving a partial response (PR). Weuse the International Myeloma Working Group (IMWG) definitions of response,which involve monitoring the surrogate markers of efficacy, M protein and FLC.The IMWG defines a PR as a greater than or equal to 50% decrease in FLC levels(for patients in whom M protein is unmeasurable) or 50% or greater decrease in Mprotein. The patient experiencing a PR had an 82% reduction in FLC. This patientdid not produce M protein, had received seven prior lines of treatment includingradiation, stem cell transplantation and multiple triple combination treatmentsincluding one with daratumumab that was not tolerated. One patient experiencingstable disease attained a 44% reduction in M protein. In January 2019, weannounced that the pooled mOS data from the first four cohorts was 22.0 months.In late 2018, we modified this study to evaluate a fractionated dosing strategyto potentially increase efficacy and decrease adverse events.

Following the determination that all prior dosing cohorts were safe andtolerated, we initiated a cohort 7 utilizing a 40mCi/m2 fractionated doseadministered 20mCi/m2 (~40mCi TBD) on days 1 and day 8. Cohort 7 was the highestpre-planned dose cohort and subjects have completed the evaluation period. Finalstudy report and study close-out will be completed later this year.

In May 2019, we announced that the FDA granted Fast Track Designation for CLR131 in fourth line or later r/r MM. CLR 131 is our small-moleculeradiotherapeutic PDC designed to deliver cytotoxic radiation directly andselectively to cancer cells and cancer stem cells. It is currently beingevaluated in our ongoing CLOVER-1 Phase 2 clinical study in patients withrelapsed or refractory multiple myeloma and other select B-cell lymphomas.

Phase 1 Study in r/r Pediatric Patients with select Solid tumors, Lymphomas andMalignant Brain Tumors

In December 2017 the Division of Oncology at the FDA accepted our IND and studydesign for the Phase 1 study of CLR 131 in children and adolescents with selectrare and orphan designated cancers. This study was initiated during the firstquarter of 2019. In December 2017, we filed an IND application for r/r pediatricpatients with select solid tumors, lymphomas and malignant brain tumors. ThePhase 1 clinical study of CLR 131 is an open-label, sequential-group,dose-escalation study evaluating the safety and tolerability of intravenousadministration of CLR 131 in up to 30 children and adolescents with cancersincluding neuroblastoma, sarcomas, lymphomas (including Hodgkin's lymphoma) andmalignant brain tumors. Secondary objectives of the study are to identify therecommended Phase 2 dose of CLR 131 and to determine preliminary antitumoractivity (treatment response) of CLR 131 in children and adolescents. In 2018,the FDA granted OD and RPDD for CLR 131 for the treatment of neuroblastoma,rhabdomyosarcoma, Ewing's sarcoma and osteosarcoma. Should any of theseindications reach approval, the RPDD would enable us to receive a priorityreview voucher. Priority review vouchers can be used by the sponsor to receivepriority review for a future New Drug Application ("NDA") or Biologic LicenseApplication ("BLA") submission, which would reduce the FDA review time from 12months to six months. Currently, these vouchers can also be transferred or soldto another entity.

Phase 1 Study in r/r Head and Neck Cancer

In August 2016, the University of Wisconsin Carbone Cancer Center ("UWCCC") wasawarded a five-year Specialized Programs of Research Excellence ("SPORE") grantof $12,000,000 from the National Cancer Institute and the National Institute ofDental and Craniofacial Research to improve treatments and outcomes for head andneck cancer, HNC, patients. HNC is the sixth most common cancer across the worldwith approximately 56,000 new patients diagnosed every year in the U.S. As a keycomponent of this grant, the UWCCC researchers completed testing of CLR 131 invarious animal HNC models and initiated the first human clinical trial enrollingup to 30 patients combining CLR 131 and external beam radiation with recurrentHNC in Q4 2019. This clinical trial was suspended due to the COVID-19 pandemicbut has now been reopened for enrolment.

We believe our PDC platform has potential to provide targeted delivery of adiverse range of oncologic payloads, as exemplified by the product candidateslisted below, that may result in improvements upon current standard of care("SOC") for the treatment of a broad range of human cancers:

Research and development expense. Research and development expense consist ofcosts incurred in identifying, developing and testing, and manufacturing productcandidates, which primarily include salaries and related expenses for personnel,cost of manufacturing materials and contract manufacturing fees paid to contractmanufacturers and contract research organizations, fees paid to medicalinstitutions for clinical trials, and costs to secure intellectual property. TheCompany analyzes its research and development expenses based on four categoriesas follows: clinical project costs, preclinical project costs, manufacturing andrelated costs, and general research and development costs that are not allocatedto the functional project costs, including personnel costs, facility costs,related overhead costs and patent costs.

General and administrative expense. General and administrative expense consistsprimarily of salaries and other related costs for personnel in executive,finance and administrative functions. Other costs include insurance, costs forpublic company activities, investor relations, directors' fees and professionalfees for legal and accounting services.

Three Months Ended June 30, 2020 and 2019

Research and Development. Research and development expense for the three monthsended June 30, 2020 was approximately $2,465,000 compared to approximately$1,810,000 for the three months ended June 30, 2019.

The following table is an approximate comparison summary of research anddevelopment costs for the three months ended June 30, 2020 and June 30, 2019:

General research and development costs 1,018,000 384,000 634,000

The overall increase in research and development expense of $655,000, or 36%,was primarily a result of increased general research and development costsresulting from increased personnel related costs and in clinical project costs.Manufacturing and related costs decreased due to a decrease in materialsproduction processes and related costs. Pre-clinical study costs were relativelyconsistent.

General and administrative. General and administrative expense for the threemonths ended June 30, 2020 was approximately $1,157,000, compared toapproximately $1,391,000 in the three months ended June 30, 2019. The decreaseof approximately $234,000, or 17%, was primarily a result of lower stock-basedcompensation expense.

Six Months Ended June 30, 2020 and 2019

Research and Development. Research and development expense for the six monthsended June 30, 2020 was approximately $5,082,000 compared to approximately$4,118,000 for the six months ended June 30, 2019.

The following table is a comparison summary of research and development costsfor the six months ended June 30, 2020 and June 30, 2019:

General research and development costs 1,779,000 914,000 865,000

The overall increase in research and development expense of approximately$964,000, or 23%, was primarily a result of increased general research anddevelopment costs resulting from increased personnel related costs and inclinical project costs. Manufacturing and related costs decreased due to adecrease in materials production processes and related costs. Pre-clinical studycosts were relatively consistent.

General and Administrative. General and administrative expense for the sixmonths ended June 30, 2020 was approximately $2,499,000, compared toapproximately $2,712,000 in the six months ended June 30, 2019. The decrease ofapproximately $213,000, or 8%, was primarily a result of lower stock-basedcompensation expense.

Liquidity and Capital Resources

As of June 30, 2020, we had cash and cash equivalents of approximately$22,450,000 compared to $10,615,000 as of December 31, 2019. This increase wasdue primarily to the approximately $18,300,000 of net proceeds received inconnection with the June 5, 2020 public offering. Net cash used in operatingactivities during the six months ended June 30, 2020 was approximately$6,562,000.

Our cash requirements have historically been for our research and developmentactivities, finance and administrative costs, capital expenditures and overallworking capital. We have experienced negative operating cash flows sinceinception and have funded our operations primarily from sales of common stockand other securities. As of June 30, 2020, we had an accumulated deficit ofapproximately $119,251,000.

We believe that the cash balance is adequate to fund our basic budgetedoperations for at least 12 months from the filing of these financial statements.However, our future results of operations involve significant risks anduncertainties. Our ability to execute our operating plan beyond that timedepends on our ability to obtain additional funding via the sale of equityand/or debt securities, a strategic transaction or otherwise. We plan toactively pursue all available financing alternatives; however, there can be noassurance that we will obtain the necessary funding. Other than theuncertainties regarding our ability to obtain additional funding, there arecurrently no known trends, demands, commitments, events or uncertainties thatare likely to materially affect our liquidity. Because we have had recurringlosses and negative cash flows from operating activities, and in light of ourexpected expenditures, the report of our independent auditors with respect tothe financial statements as of December 31, 2019 and for the year ended December31, 2019 contains an explanatory paragraph as to the potential inability tocontinue as a going concern. This opinion indicated at that time, thatsubstantial doubt existed regarding our ability to remain in business.

The Trouble With CRISPR The Strand – Strand

By daniellenierenberg

CRISPR is a catchy acronym that originally described a naturally occurring gene editing tool, derived from a bacterial defense mechanism against viruses. Its the name on everybodys lips in the intersecting realms of science, medicine, ethics, and politics. From the moment of its discovery, CRISPR-Cas9 looked like a miraculous solution to all of the problems that gene editing efforts have experienced over decades of trial and error. This revolutionary new gene editing technique has opened the doors to both massive scientific progress and ethical controversy. Now more than ever, were seeing that CRISPR still has massive kinks to work out. Can we ever fully understand the social and scientific implications of gene editing, and should we use it in humans before we learn how to properly harness it?

What is gene editing?

The 20th century saw genetic scientists increasingly focus their pursuits on the sub-microscopic. As science delved deeper into the human body in an attempt to uncover the molecular minutiae of life, the possibility of reaching into the cell and manipulating its genetic material began to look more and more real. Even by the 1950s, evidence had been mounting for decades that deoxyribonucleic acid (DNA), an unassuming molecule residing in a central cellular compartment called the nucleus, was the physical genetic material that passed information from parent to child. Finally, in 1953, landmark work by Kings College biochemist Rosalind Franklin allowed Cambridge researchers to reveal the structure of DNA and confirm its role in heredity once and for all.

Starting from a hesitant foundation, molecular genetics exploded in both scope and popularity over subsequent decades. With the secrets of heredity increasingly out in the open, human ambition demanded that we try to bend DNA to our willand now we can. These days, targeted gene editing techniques revolve around artificially-engineered molecular tools known as nucleases, whose earliest use was in 1996not even 50 years after the discovery of DNAs structure. Engineered nucleases are often described as molecular scissors. Fundamentally, they have two main parts: one part that finds and grabs onto the target DNA within a cell, and one part that snips a piece out of that DNA.

How CRISPR works

CRISPR is similar to other directed nucleases, but its much better at its job. The CRISPR part is secondary to the systems gene editing applications; the truly important discovery, which Jennifer Doudna made in 2012, was a protein that she called CRISPR-associated protein 9, or Cas9. This protein is the nuclease tool, the pair of molecular scissors that finds, sticks to, and snips target DNAand its more accurate than anything weve ever seen before.

In bacteria, CRISPR is a section of the genome that acts as an immune memory, storing little snippets of different viruses genetic material as DNA after failed infections, like trophies. When a once-active virus attempts to invade a bacterium, the mobile helper Cas9 copies down the relevant snippet from CRISPR in the form of ribonucleic acid, or RNA. RNA is a molecule thats virtually identical to DNA, except for one extra oxygen atom. Because of this property, the RNA sequence that Cas9 holds can pair exactly, nucleotide by nucleotide, with the viral targets DNA, making it extremely efficient at finding that DNA. With a freshly transcribed RNA guide, the bacterium can deploy Cas9 to findand cut outthe corresponding section of viral genetic material, rendering the attacker harmless.

The existence of CRISPR in bacteria was old news by 2012, but Doudnas discovery of Cas9s function was revolutionary. With a little creativity and ingenuity, such a simple and accurate nuclease can be modified to be much more than just a pair of scissors. Using synthetic RNA guides and certain tweaks, Cas9 can be used to remove specific genes, cause new insertions to genomes, tag DNA sequences with fluorescent probes, and much more.

The possibilities seem endless.What if we could go into the body of a human affected by a hereditary disease and change that persons DNA to cure them? What if we could modify reproductive germ cells in human bodies (which give rise to sperm and eggs), or make targeted genetic edits in the very first cell of an embryo? Nine months of division and multiplication later, that cell would give rise to a human being whose very nature has been deliberately tweakedand their childrens nature, and their childrens. With the accuracy and accessibility of the CRISPR/Cas9 system, these ideas arent hypotheticals. In 2019, CRISPR edits in bone marrow stem cells were successfully used to cure sickle cell anemia in a Mississippi woman. Beta thalassaemia, another genetic disease of the blood, has also been treated this way. In 2018, Chinese scientist He Jiankui even claimed that he had conferred HIV immunity upon twin girls using embryonic editing.

CRISPRs complications

At first glance, CRISPR looks like a miraclebut it isnt perfect. What if some cells were affected by edits, but others werent, creating a strange genetic mosaic in a human body? What if, in trying to modify a specific gene, we accidentally hit a different section of DNA nearby? What if we got the right gene, but it also affected a different part of the body that we didnt know about?

These problems arent hypotheticals either. So-called mosaicism and off-target editing are huge concerns among CRISPR scientists. Mosaicism is of particular concern in embryonic editing. Though CRISPR injections are carried out when an embryo is single-celled, CRISPR doesnt always appear to work until after several rounds of cell divisionand it doesnt work in every cell. If not all the cells in the body are affected by gene editing that is intended to eliminate a genetic disease, the disease could remain in the body. It may be possible to combat mosaicism with faster gene editing (so that cells dont replicate before theyve had a chance to become CRISPR-modified), altering sperm and egg cells before they meet to form an embryo, and developing more precise CRISPR gene editing which is in itself a challenge, thanks to off-target editing.

In nature, a little bit of off-target editing could actually make the CRISPR-Cas9 defense system stronger with the principle of redundancy. Flexibility in the form of imprecision could allow a bacterium to neutralize viruses whose exact genetic sequences have not yet been encountered: viruses related to, but not identical to, previous attackers. In clinical and therapeutic applications, on the other hand, precision is everything. And unfortunately, as time passes, CRISPRs level of precision seems further and further off. Preprints released just this year reveal that the frequency and magnitude of CRISPRs off-target edits in human cells may be worse than we had previously known. Large proportions of cells with massive unwanted DNA deletions, losses of entire chromosomes in experimental embryos, and shuffling of genetic sequences were observed.

Of course, not only do scientists need to avoid off-target edits, but they also need to know when such undesired edits have occurred. Off-target effects can be detected by genome sequencing and computer prediction tools, but theres no perfect way to do it yetthere may still be editing misses that were, well, missing. Off-target edits themselves could be minimized by altering the RNA transcript that Cas9 carries to make it more accurate, altering Cas9 itself, or reducing the actual amount of Cas9 protein released into the cell (though this could also reduce on-target effects). Replacing Cas9 itself with other Cas variants, like smaller and more easily deliverable CasX and CasY proteins, is a promising possibility for more efficient editing, but these candidates still run into many of the same problems as Cas9. More strategies are constantly being discovered, proposed, and explored, but were still nowhere near perfect.

Perhaps most importantly, even barring any purely technical problems, is that humans remain in sheer ignorance of much of the extent and consequences of pleiotropy, a phenomenon where a genes presence or deletion has more than one effect in the human body. Even genes whose function we think we know well might have totally unexpected additional functions. On the other side of the coin, we dont have a comprehensive understanding of how many different genetic contributors there are to any given trait or disease, much less where they lie in the genome. We dont understand the way that thousands of variations across the entire genome contribute to appearance, personality, and health. Assuming that some genes are good and others are bad is morally dangerous, and scientifically reprehensible. In reality, we are not ready for genetic determinism, and may never be.

A great responsibility

Humanity has discovered a great power, but we all know what comes with great power. Questions of which edits are necessary for health (is mild Harlequin syndrome a disease or a cosmetic concern?), whether edits are ethical (should autism and homosexuality be considered curable conditions?), and the possibility of designer babies, among others, are pertinent and require thorough discussion. We also need to realize that making these types of changes isnt our decision until we can get CRISPR right, and understand the genome well enough to target particular phenotypes. Though most scientists are aware of the difficulties of CRISPR and its use is generally tightly regulated, some scientistsand laypeopleare less careful. He Jiankuis apparent miracle HIV cure led to his arrest and imprisonment for unapproved and unethical practice. Its no great surprise that his work likely fell prey to off-target effects and mosaicism; even if he got it right, his intended change could alter cognitive function, and who knows what else?

Non-scientists are getting involved too: in 2018, self-proclaimed biohacker Josiah Zayner publicly injected his own arm with what he claimed was muscle-enhancing CRISPR. Though Zayner is one of the most vocal, hes not the only one of his kind. Quieter biohackers, untrained people without a scientific background or a good understanding of how CRISPR can go wrong, are attempting to edit themselves and even their pets.

Laypeople have an unquestionable place in science: the scientific discipline needs fresh perspectives and creativity that stuffy academics cant offer. CRISPR is still in its infancy, though. Before we know much, much more about its capabilities and consequences, there can be no place for black market gene editing kits, rogue scientists altering human embryonic and germline DNA, or basement geneticists injecting Cas9 into their dogs. Who can say what effects these interventions might have, not just on edited individuals, but on the futures of entire species?

Some say that gene editing is an act of hubris, destined to backfire spectacularly and horrendously. Others believe that its our responsibility to use CRISPR to improve lives. Which of these opinions is true depends on how science walks a narrow tightrope, though Im inclined to agree with the latterand add that our responsibility is not just to master gene editing, but to make clear and public its many faults and failings. The truth, in all its complexity, needs to overcome pop sciences oversimplification and sensationalism. Promising new advances and techniques are on the horizon, but we have a long way to go. Gene editing is no joke; humanity is playing with fire. With an incredibly accurate and accessible nuclease making its way into labs and garages across the world (while its flaws continue to be uncovered year by year), it is more important than ever for the world to understand and discuss the long-reaching consequences and responsible use of gene editing technology. CRISPR is not a miracle, but gene editing may very well be the future of humanityand its on us to keep it under control.

Scientists Create Hair-Bearing Human Skin from Pluripotent …

By daniellenierenberg

A team of researchers from several U.S. institutions has created an organoid culture system that generates complex skin from human pluripotent stem cells.

A hair-bearing skin organoid. Image credit: Indiana University School of Medicine.

This is the first study to show that human hair can be grown completely from stem cells in a dish, which has been a goal of the skin biology community for decades, said lead author Dr. Karl Koehler, from Harvard Medical School and Boston Childrens Hospital.

Through the 3D culture technique developed in past studies, Dr. Koehler and colleagues incubated human stem cells for about 150 days in a skin organoid.

Weve developed a new cooking recipe for generating human skin that produces hair follicles after about 70 days in culture, Dr. Koehler explained.

When the hair follicles grow, the roots extend outward radially. Its a bizarre-looking structure, appearing almost like a deep-sea creature with tentacles coming out from it.

After the incubation period, researchers tested whether skin organoids could integrate on the skin of nude mice. More than half of the organoids they grafted on the mice grew human hair follicles.

The skin organoid developed from culture is akin to fetal facial skin and hair, he said.

The teams experiments show that organoid generated hairy skin can integrate into mouse skin, which suggests potential applications in skin and facial reconstruction.

This could be a huge innovation, providing a potentially unlimited source of soft tissue and hair follicles for reconstructive surgeries, said first author Dr. Jiyoon Lee, also from Harvard Medical School and Boston Childrens Hospital.

Skin regeneration is of great interest for treating patients, added co-author Dr. Taha Shipchandler, from the Indiana University School of Medicine.

If we can harness this growth into a medium, and easily apply it to patients, it would change the way we treat many injuries or reconstructions. This would have a profound effect on the medical field.

The results were published in the journal Nature.

How Close Are We To Making Babies from Bone Marrow? – Discover Magazine

By daniellenierenberg

In 2007, a group of researchers reported a startling discovery: They had created sperm-like cells out of stem cells taken from the bone marrow of human men. Two years later, however, the study was retracted due to charges of plagiarism. Thirteen years later, the ability to create functional human sperm out of stem cells remains elusive.

Scientists have been trying to figure out how to create functioning human gametes eggs and sperm from stem cells for 20 or 30 years, says Vittorio Sebastiano, a stem cell biologist at Stanford University whose research focuses on reproductive biology. Doing so would help people struggling with infertility have children and help scientists unlock the secrets of human development. Since 2007, scientists have made considerable progress on this front, creating healthy mouse pups from stem cell-generated gametes and even immature human egg cells. But there is still a long road ahead before scientists will be able to convert skin or bone marrow into babies.

We are trying to really find ways to efficiently, robustly generate germ cells that can be, in the short term, used to understand the biology of these concepts, but in the long term [used to be] able to restore fertility, says Sebastiano.

When the first baby conceived via in vitro fertilization (IVF) was born in 1978, it was a major step forward for reproductive science and a precursor to the stem cell research conducted by Sebastiano and others today, he says. But IVF is not an option for every individual or couple trying to have a biological child, including those who are born without gametes or who receive aggressive cancer treatments at a young age. This scientific technique would offer these individuals a new shot at reproduction.

The next major step came in the 2000s, with the creation of induced pluripotent stem cells (iPSCs). These cells are taken from blood or skin cells and reprogrammed to behave like embryonic cells, which have the ability to develop into any type of cell in the body. Since then, researchers have been trying to figure out how to turn these embryonic-like cells into functional sperm and eggs.

Part of what has made this work so challenging is that scientists havent been able to fully grasp what happens in a human embryo during normal development, says Sebastiano. Scientists understand this process in mice because the rodents are easy to study in the lab. But ethical restrictions and technical factors (like having access to the embryos at just the right point in time) make this phenomenon hard to study in people, he says.

Despite the roadblocks, scientists have made significant progress in the last 10 years. In 2012, a group of researchers in Japan created fertile mouse eggs from iPSCs and used those eggs to breed healthy mouse pups. In [the] mouse, the whole circle has already been completed, says Sebastiano. Now it has been shown by a couple of groups in the UK and in Japan that you can generate embryonic-like cells from mice and then you can actually push these cells to become eggs or sperm, fully functional.

In 2018, the same group of Japanese scientists made another major breakthrough. Using human blood cells and the pluripotent stem cell technique, they managed to produce immature human eggs.

Similar efforts to create sperm are not as far along, says Sebastiano. Several efforts over the years have purported to create sperm-like cells, including the 2007 blood marrow study. A much-heralded study published in 2014 also made major news, but Sebastiano says the development of the cells in that study didnt go far beyond the earliest stages of differentiation.

But, we are actively working on it, says Sebastiano. Probably in the next few years we will be able to generate fully functional sperm and fully functional oocytes. Then, the question will be how do scientists test the quality of these gametes, he says.

The only way to fully assess the quality and functionality of a sperm or egg is to use it to, well, try to fertilize another gamete and produce a baby. Thats why this work has to be approached with the utmost care, says Sebastiano. He hypothesizes that once scientists have developed techniques that they think produce mature human oocytes and sperm, the next step will be testing these techniques in primates. That way, researchers can follow the entire life of individual animals produced from this technique to see if any unexpected problems develop, he says.

Sebastiano has no doubt that one day, these stem cells could help individuals struggling with infertility to produce healthy children. This, along with a fascination with biological development, is what drives Sebastianos work. There are also, of course, significant ethical considerations that have to be carefully considered. This technique has the potential to affect human life on a generational level, he notes. And many people also raise concerns about other future consequences, like the ability to create designer babies or produce offspring from hairs stolen from unsuspecting celebrities. Bioethics experts have written about the need to start working through the medical and legal issues around this technique now, before it is viable.

There is a need actually to develop this, but since we are really dealing with a very unique cell type we need to be cautious, says Sebastiano.

By daniellenierenberg

This rebrand symbolizes our growth as a company and an opportunity to show our customers that we understand and are responding to their evolving skincare needs, Connie Lo, Three Ships Co-Founder, tells the press.

We invite anyone, adds Lo,interested in a more revitalized complexion to try our products and embark on their journey to better skin.

Connie Lo and Laura Burget founded NIU Body in early 2017 as an unpretentious, clean, and affordable skin care brand for their fellow millennials. We aspire to be an approachable option without the fancy fluff, at affordable prices so everyone can enjoy everything green beauty has to offer. Our products are simple in both design and formulation, explained Burget in her 2018 Indie Beauty Profile.

And those core brand qualities havent changed now that NIU Body is Three Ships: While our look has changed, says Burget in a press release shared with Cosmetics Design, we remain meticulous in our approach to sourcing sustainable ingredients and creating formulations that provide tangible benefits.

Our philosophy, she says,has and always will be to be the change we want to see in the beauty industry: natural, effective and affordable skincare with a conscience.

As with any thorough rebrand, the change from NIU Body to Three Ships is about more than just a new name. As the brand explains in a recent LinkedIn update, It really was a culmination of how we felt about our years-long journey discovering affordable skincare ingredients that actually worked for us. The destination always seems further than it appears, but as we journey towards it, we start to see the full picture. Three Ships is about the journey to better skin.

The brand has new packaging and labeling, based primarily on consumer feedback. And now the brands portfolio is full of skin care product names that highlight key ingredients and benefits, such as Clarify Tea Tree + MCT Cleansing Oil, Hydrate 49% Almond Oil Serum, and Awake Rose Hydrosol Toner.

The best anti-aging skin care products to use in your 40s – TODAY

By daniellenierenberg

For most of my life, Ive credited my good skin to two products: a gentle cleanser and a powerful sunscreen. But something happened when I hit my 40s I noticed my skin no longer glowed like it used to and it always seemed to look and feel dry. When I noticed a few sunspots on the top of my right cheek, I realized it was time to elevate my morning and evening beauty routines.

Fine lines, dryness, sunspots and a loss of firmness are all things women begin to deal with in their 40s, says Dr. Mona Gohara, associate clinical professor of dermatology at Yale School of Medicine. Plummeting estrogen levels directly affect collagen production, skin thickness and hydration, so its important to develop an anti-aging skin care program, and stick with that program, during this decade.

With so many anti-aging products on the market boasting ingredients youd never thought youd put on your face (acids! oils!), it can be hard to figure out where to start.

So we reached out to top dermatologists across the country to help simplify the process. Everyone we spoke to listed sunscreen as the most important topical to keep forty-something skin looking great, followed by the appropriate cleanser, anti-ager, moisturizer and exfoliator.

Below, you'll find a quick guide to what youll need when it comes to choosing the right ingredients for your face, because as Gohara stressed, At this age, prevention not just correction should still be your goal.

When shopping for a sunscreen in your 40s, experts note you should be looking for the words zinc oxide, titanium dioxide and iron oxide on the label.

Zinc oxide and titanium dioxide protect against both UVA and UVB rays, while iron oxide guards against skin-damaging blue light from computer and cell phone screens, notes Gohara. Look for an SPF of 30 or higher and slather on half a teaspoon on your face daily, including your ears and neck, before applying makeup. If you drive, be sure to protect your hands, as UVA rays can penetrate glass, resulting in sunspots.

EltaMD UV Facial Broad-Spectrum SPF 30+, despite having zinc oxide, doesnt leave your skin with a whiteish tint. It's also formulated with hyaluronic acid, which can help keep your skin hydrated and firm.

Supergoop! Unseen Sunscreen SPF 40 is oil-free, goes on clear and works as a makeup primer to control shine. The vegan formula should be applied as the last step in your skin care regimen before you apply makeup, at least 15 minutes before you step out into the sun.

Gohara recommends keeping this brush-on SPF powder in your glove compartment. With SPF 50, the water-resistant formula provides both protection and sheer tinted coverage.

In your 40s, derms recommend using a cleanser containing ceramides, glycerin, and vitamin E.

Ceramides are lipids that help retain moisture, glycerin is a humectant that pulls water from the deepest layers of the skin, while vitamin E also adds moisture, says Dr. Martha Viera, volunteer faculty at the University of Miami Department of Dermatology. Before cleansing, wash your hands thoroughly to avoid dirt or bacteria from touching your skin, and splash your face with lukewarm water prior to application to activate the cleansing ingredients. Start and end your day by washing with a quarter-sized amount of cleanser, applying it in a circular motion over your face and neck.

Viera likes La Roche-Posay Toleriane Hydrating Gentle Cleanser because its designed to balance the skins pH levels, protecting the skins sensitive barrier. It is formulated to cleanse the skin without stripping it of moisture thanks to ingredients such as glycerin and niacinamide.

Bioderma Sensibio Foaming Gel has a soothing gel-cream texture that turns to foam when activated. The gentle formula works to remove makeup while also hydrating the skin.

Dove White Beauty Bar with Deep Moisture is great for sensitive skin as it combines cleansing ingredients with a dose of moisturizing cream. It is suitable for sensitive skin and gentle enough to use on both your face and body.

Youll need two anti-aging products in your 40s: a morning serum that contains moisture-drawing hyaluronic acid and antioxidants, and a night serum that includes peptides and retinol (retinol should be applied at night as it can make your skin sensitive to the sun).

Be sure to layer your anti-ager under your moisturizer and consider a serum which, thanks to their small molecular makeup, absorbs quickly and deeply, says Dr. Arisa Ortiz, director of laser and cosmetic dermatology at the University of California at San Diego. Antioxidants like vitamin C, E, B5, and resveratrol attach themselves to free radicals, preventing the free radicals from latching onto and damaging healthy skin cells, while retinoids and peptides exfoliate dead skin while stimulating collagen and softening lines.

Obagi Professional-C Serum contains ascorbic acid, a vitamin C derivative that softens the look of pigmentation and encourages collagen growth. It can be applied to the face, neck and chest in the mornings and followed with sunscreen.

Dr. Ortiz likes Rodan + Fields Intensive Renewing Serum because its lightweight, absorbs easily and has the highest levels of vitamin A for a nonprescription product. The serums are held in small capsules that you can open to smooth all over your skin.

Stuff We Love

Get a daily roundup of items that will make your life easier, healthier and more stylish.

This dermatologist-approved pick is suitable for normal, sensitive and dry skin. The formula works to not only visibly brighten the skin but also reduce the appearance of fine lines and wrinkles.

To tackle dry skin in your 40s, Gohora recommends looking for ingredients that help boost and maintain moisture, including niacinamide, ceramides, glycerin and hyaluronic acid.

To be most effective, apply your moisturizer after your anti-aging serum. Dot your cheeks, forehead, chin and nose, and then rub in a circular upward motion both morning and night, notes Dr. Paul Jarrod Frank, clinical assistant professor of dermatology at The Icahn School of Medicine at Mount Sinai Hospital and author of "The Pro-Aging Playbook."

This moisturizer comes in a soothing light gel-cream formula and uses hyaluronic acid to fortify the lipid barrier to prevent dryness. It can be applied twice daily after a serum is applied to the skin.

Pause Collagen Boosting Moisturizer contains skin-conditioning fatty acids and B vitamins that work to promote healthy skin. The formula features the brand's "Pause Complex," which combines vitamins, antioxidants and peptides that help boost collagen production.

Dr. Frank likes Caudalie Vinoperfect Brightening Moisturizer, a lightweight gel that contains niacinamide and hyaluronic acid for a boost of hydration. It can be applied in the mornings to the face and neck in order to brighten and moisturize the skin.

Acids in exfoliators help remove layers of dead skin cells to promote cell turnover, clear pores and reduce pigmentation. Look for words such as glycolic, lactic, mandelic or salicylic acid on the label.

Apply a dime-sized amount of facial exfoliator two to three times a week at night, Jarrod told us. Just dont overdo it too much exfoliation can rob skin of the fatty acids that protect the skin barrier.

This treatment addresses skin care concerns by exfoliating, purifying and smoothing the skin. Depending on your skin type, it can be used up to three times a week to improve the appearance of your complexion.

Dr. Frank likes Drunk Elephant T.L.C. Sukari Babyfacial, which has an eye-popping 25% glycolic and lactic acid blend to smooth and brighten skin. Since the formula uses clean ingredients, it is fragrance-free and won't leave the skin feeling irritated.

A derivative of salicylic acid can be found in Lancme Renergie Lift Multi-Action Ultra Milk Peel, a leave-on exfoliator that you apply after cleansing and before your moisturizer. The milky consistency feels smooth on the skin and should be applied with a cotton round.

Dermalogica Daily Microfoliant contains salicylic acid and foams up into a paste when activated with water. The formula can be applied daily to the skin to slough off dead skin cells and even out your complexion.

Although it is a bit of a splurge, this daily serum uses rich ingredients such as mandelic and lactic acid to unclog pores, even skin texture, reduce the appearance of fine lines and more. It can be applied to the face and neck to reveal brighter skin over time.

Bonus products: Our experts noted theres no harm incorporating a neck or eye cream into your routine in your 40s.

Look for targeted ingredients in a neck cream, such as tetrapeptides to promote collagen formation, antioxidant algae extract to protect against free radicals, glucosamine to stimulate hyaluronic acid and improve hydration while decreasing wrinkles, and omega-3 fatty acids to add moisture.

Apply a dime-size amount in the morning and evening, working your way up the neck to the jawline until the product is evenly distributed and absorbed, notes Gohara. Neck creams tend to be thicker than traditional moisturizers, so allow more time for them to absorb and be sure to follow up with a sunscreen in the morning.

Viera likes Revision Nectifirm Advanced, which uses peptides to smooth dry skin. Other ingredients such as lingonberry extract work with the skin's natural microbiome to provide soothing results.

Prai Ageless Throat & Dcolletage Creme has shea butter and hyaluronic acid to plump lines and effectively smooth the skin. For best results, the brand recommends applying the moisturizer twice daily to target areas.

Suzanne Somers Organics Neck Firming Crme contains tetrapeptides to support collagen and elastin growth. The formula is packed with skin-boosting ingredients such as hyaluronic acid and Swiss apple stem cells that help to combat signs of aging.

This cream can be applied twice daily in upward motions to hydrate and revitalize the skin. The formula is quick-absorbing, so it won't leave the skin feeling oily or greasy.

Look for ingredients like caffeine to reduce puffiness and dark circles, niacinamide and hyaluronic acid to plump fine lines, and arginine, growth factors, and retinol to boost collagen production.

Apply a pea-sized amount twice daily by gently patting the cream on with your ring finger, Viera said. Be sure to use any eye products containing retinoids at night to avoid sun sensitivity.

Dr. Viera likes Neocutis Lumire Illuminating Eye Cream, a lightweight cream that contains antioxidants to protect against environmental damage. In addition to its protective qualities, it can also be used to reduce the appearance of puffiness and dark circles.

RoC Retinol Correxion Eye Cream uses a derivative of vitamin A to accelerate the removal of dead skin cells, leaving you with visibly brighter skin. It targets concerns such as crow's feet, under-eye wrinkles, deep wrinkles and fine lines.

Skinbetter Science Interfuse Eye Treatment Cream contains caffeine to reduce puffiness and vitamin C to brighten the under-eye area. It is packed with humectants to help lock in moisture and promote healthy skin.

Coronavirus Drug and Treatment Tracker – The New York Times

By daniellenierenberg

The Covid-19 pandemic is one of the greatest challenges modern medicine has ever faced. Doctors and scientists are scrambling to find treatments and drugs that can save the lives of infected people and perhaps even prevent them from getting sick in the first place.

Below is an updated list of 20 of the most-talked-about treatments for the coronavirus. While some are accumulating evidence that theyre effective, most are still at early stages of research. We also included a warning about a few that are just bunk.

We are following 20 coronavirus treatments for effectiveness and safety:

Tentative or

mixed evidence

We are following 20 coronavirus treatments

for effectiveness and safety:

Tentative or

mixed evidence

We are following 20 coronavirus treatments

for effectiveness and safety:

There is no cure yet for Covid-19. And even the most promising treatments to date only help certain groups of patients and await validation from further trials. The F.D.A. has not fully licensed any treatment specifically for the coronavirus. Although it has granted emergency use authorization to some treatments, their effectiveness against Covid-19 has yet to be demonstrated in large-scale, randomized clinical trials.

This list provides a snapshot of the latest research on the coronavirus, but does not constitute medical endorsements. Always consult your doctor about treatments for Covid-19.

New additions and recent updates:

Added ivermectin, a drug typically used against parasitic worms that is being increasingly prescribed in Latin America. Aug. 10

Updated descriptions for several treatments. Aug. 10

We will update and expand the list as new evidence emerges. For details on evaluating treatments, see the N.I.H. Covid-19 Treatment Guidelines. For the current status of vaccine development, see our Coronavirus Vaccine Tracker.

WIDELY USED: These treatments have been used widely by doctors and nurses to treat patients hospitalized for diseases that affect the respiratory system, including Covid-19.

PROMISING EVIDENCE: Early evidence from studies on patients suggests effectiveness, but more research is needed. This category includes treatments that have shown improvements in morbidity, mortality and recovery in at least one randomized controlled trial, in which some people get a treatment and others get a placebo.

TENTATIVE OR MIXED EVIDENCE: Some treatments show promising results in cells or animals, which need to be confirmed in people. Others have yielded encouraging results in retrospective studies in humans, which look at existing datasets rather than starting a new trial. Some treatments have produced different results in different experiments, raising the need for larger, more rigorously designed studies to clear up the confusion.

NOT PROMISING: Early evidence suggests that these treatments do not work.

PSEUDOSCIENCE OR FRAUD: These are not treatments that researchers have ever considered using for Covid-19. Experts have warned against trying them, because they do not help against the disease and can instead be dangerous. Some people have even been arrested for their false promises of a Covid-19 cure.

EVIDENCE IN CELLS, ANIMALS or HUMANS: These labels indicate where the evidence for a treatment comes from. Researchers often start out with experiments on cells and then move onto animals. Many of those animal experiments often fail; if they dont, researchers may consider moving on to research on humans, such as retrospective studies or randomized clinical trials. In some cases, scientists are testing out treatments that were developed for other diseases, allowing them to move directly to human trials for Covid-19.

All treatmentsWidely usedPromisingTentative or mixedNot promisingPseudoscience

Antivirals can stop viruses such as H.I.V. and hepatitis C from hijacking our cells. Scientists are searching for antivirals that work against the new coronavirus.

PROMISING EVIDENCE EVIDENCE IN CELLS, ANIMALS AND HUMANSEMERGENCY USE AUTHORIZATIONRemdesivirRemdesivir, made by Gilead Sciences, was the first drug to get emergency authorization from the F.D.A. for use on Covid-19. It stops viruses from replicating by inserting itself into new viral genes. Remdesivir was originally tested as an antiviral against Ebola and Hepatitis C, only to deliver lackluster results. But preliminary data from trials that began this spring suggested the drug can reduce the recovery time of people hospitalized with Covid-19 from 15 to 11 days. (The study defined recovery as either discharge from the hospital or hospitalization for infection-control purposes only.) These early results did not show any effect on mortality, though retrospective data released in July hints that the drug might reduce death rates among those who are very ill.

TENTATIVE OR MIXED EVIDENCE EVIDENCE IN CELLS, ANIMALS AND HUMANSFavipiravirOriginally designed to beat back influenza, favipiravir blocks a viruss ability to copy its genetic material. A small study in March indicated the drug might help purge the coronavirus from the airway, but results from larger, well-designed clinical trials are still pending.

TENTATIVE OR MIXED EVIDENCE EVIDENCE IN CELLS, ANIMALS AND HUMANSMK-4482Another antiviral originally designed to fight the flu, MK-4482 (previously known as EIDD-2801) has had promising results against the new coronavirus in studies in cells and on animals. Merck, which has been running clinical trials on the drug this summer, has announced it will launch a large Phase III trial in September.Updated Aug. 6

TENTATIVE OR MIXED EVIDENCE EVIDENCE IN CELLS Recombinant ACE-2To enter cells, the coronavirus must first unlock them a feat it accomplishes by latching onto a human protein called ACE-2. Scientists have created artificial ACE-2 proteins which might be able to act as decoys, luring the coronavirus away from vulnerable cells. Recombinant ACE-2 proteins have shown promising results in experiments on cells, but not yet in animals or people.

TENTATIVE OR MIXED EVIDENCE EVIDENCE IN CELLS AND HUMANS IvermectinFor decades, ivermectin has served as a potent drug to treat parasitic worms. Doctors use it against river blindness and other diseases, while veterinarians give dogs a different formulation to cure heartworm. Studies on cells have suggested ivermectin might also kill viruses. But scientists have yet to find evidence in animal studies or human trials that it can treat viral diseases. As a result, Ivermectin is not approved to use as an antiviral.

In April, Australian researchers reported that the drug blocked coronaviruses in cell cultures, but they used a dosage that was so high it might have dangerous side effects in people. The FDA immediately issued a warning against taking pet medications to treat or prevent Covid-19. These animal drugs can cause serious harm in people, the agency warned.

Since then a number of clinical trials have been launched to see if a safe dose of ivermectin can fight Covid-19. In Singapore, for example, the National University Hospital is running a 5,000-person trial to see if it can prevent people from getting infected. As of now, theres no firm evidence that it works. Nevertheless ivermectin is being prescribed increasingly often in Latin America, much to the distress of disease experts.Updated Aug. 10

NOT PROMISING EVIDENCE IN CELLS AND HUMANS Lopinavir and ritonavirTwenty years ago, the F.D.A. approved this combination of drugs to treat H.I.V. Recently, researchers tried them out on the new coronavirus and found that they stopped the virus from replicating. But clinical trials in patients proved disappointing. In early July, the World Health Organization suspended trials on patients hospitalized for Covid-19. They didnt rule out studies to see if the drugs could help patients not sick enough to be hospitalized, or to prevent people exposed to the new coronavirus from falling ill. The drug could also still have a role to play in certain combination treatments.

NOT PROMISING EVIDENCE IN CELLS, ANIMALS AND HUMANSHydroxychloroquine and chloroquineGerman chemists synthesized chloroquine in the 1930s as a drug against malaria. A less toxic version, called hydroxychloroquine, was invented in 1946, and later was approved for other diseases such as lupus and rheumatoid arthritis. At the start of the Covid-19 pandemic, researchers discovered that both drugs could stop the coronavirus from replicating in cells.

Since then, theyve had a tumultuous ride. A few small studies on patients offered some hope that hydroxychloroquine could treat Covid-19. The World Health Organization launched a randomized clinical trial in March to see if it was indeed safe and effective for Covid-19, as did Novartis and a number of universities. Meanwhile, President Trump repeatedly promoted hydroxychloroquine at press conferences, touting it as a game changer, and even took it himself. The F.D.A. temporarily granted hydroxychloroquine emergency authorization for use in Covid-19 patients which a whistleblower later claimed was the result of political pressure. In the wake of the drugs newfound publicity, demand spiked, resulting in shortages for people who rely on hydroxychloroquine as a treatment for other diseases.

But more detailed studies proved disappointing. A study on monkeys found that hydroxychloroquine didnt prevent the animals from getting infected and didnt clear the virus once they got sick. Randomized clinical trials found that hydroxychloroquine didnt help people with Covid-19 get better or prevent healthy people from contracting the coronavirus. Another randomized clinical trial found that giving hydroxychloroquine to people right after being diagnosed with Covid-19 didnt reduce the severity of their disease. (One large-scale study that concluded the drug was harmful as well was later retracted.) The World Health Organization, the National Institutes of Health and Novartis have since halted trials investigating hydroxychloroquine as a treatment for Covid-19, and the F.D.A. revoked its emergency approval. The F.D.A. now warns that the drug can cause a host of serious side effects to the heart and other organs when used to treat Covid-19.

In July, researchers at Henry Ford hospital in Detroit published a study finding that hydroxychloroquine was associated with a reduction in mortality in Covid-19 patients. President Trump praised the study on Twitter, but experts raised doubts about it. The study was not a randomized controlled trial, in which some people got a placebo instead of hydroxychloroquine. The studys results might not be due to the drug killing the virus. Instead, doctors may have given the drug to people who were less sick, and thus more likely to recover anyway.

Despite negative results, a number of hydroxychloroquine trials have continued, although most are small, testing a few dozen or a few hundred patients. A recent analysis by STAT and Applied XL found more than 180 ongoing clinical trials testing hydroxychloroquine or chloroquine, for treating or preventing Covid-19. Although its clear the drugs are no panacea, its theoretically possible they could provide some benefit in combination with other treatments, or when given in early stages of the disease. Only well-designed trials can determine if thats the case.Updated Aug. 10

Most people who get Covid-19 successfully fight off the virus with a strong immune response. Drugs might help people who cant mount an adequate defense.

TENTATIVE OR MIXED EVIDENCE EVIDENCE IN CELLS AND HUMANS Convalescent plasmaA century ago, doctors filtered plasma from the blood of recovered flu patients. So-called convalescent plasma, rich with antibodies, helped people sick with flu fight their illness. Now researchers are trying out this strategy on Covid-19. In May, the F.D.A. designated convalescent plasma an investigational product. That means that despite not yet being shown as safe and effective, plasma can be used in clinical trials and given to some patients who are seriously ill with Covid-19. Tens of thousands of patients in the U.S. have received plasma through a program launched by the Mayo Clinic and the federal government.

The Trump administration has praised convalescent plasma, despite the lack of evidence yet that it works. The first wave of trials have been small and the results have been mixed. Large randomized clinical trials are underway, but theyve struggled to enroll enough participants, some of whom worry they will receive a placebo instead of the treatment itself.

Experts say that its vital to complete these trials to determine if convalescent plasma is safe and effective. If these trials are successful, it could serve as an important stopgap measure until more potent therapies become widely available.Updated Aug. 10

TENTATIVE OR MIXED EVIDENCE EVIDENCE IN CELLS, ANIMALS AND HUMANSMonoclonal antibodiesConvalescent plasma from people who recover from Covid-19 contains a mix of different antibodies. Some of the molecules can attack the coronavirus, but many are directed at other pathogens. Researchers have sifted through this slurry to find the most potent antibodies against Covid-19. They have then manufactured synthetic copies of these molecules, known as monoclonal antibodies. Researchers have begun investigating them as a treatment for Covid-19, either individually or in cocktails.

Monoclonal antibodies were first developed as a therapy in the 1970s, and since then the F.D.A. has approved them for 79 diseases, ranging from cancer to AIDS. Since the start of the pandemic, researchers have found dozens of monoclonal antibodies that show promise against Covid-19 in preclinical studies on cells and animals. Companies like Eli Lilly and Regeneron recently began clinical trials studying monoclonal antibodies. Several other firms, as well as teams at universities, are slated to enter the race soon as well.Updated Aug. 10

TENTATIVE OR MIXED EVIDENCE EVIDENCE IN CELLS, ANIMALS AND HUMANSInterferonsInterferons are molecules our cells naturally produce in response to viruses. They have profound effects on the immune system, rousing it to attack the invaders, while also reining it in to avoid damaging the bodys own tissues. Injecting synthetic interferons is now a standard treatment for a number of immune disorders. Rebif, for example, is prescribed for multiple sclerosis.

As part of its strategy to attack our bodies, the coronavirus appears to tamp down interferon. That finding has encouraged researchers to see whether a boost of interferon might help people weather Covid-19, particularly early in infection. Early studies, including experiments in cells and mice, have yielded encouraging results that have led to clinical trials.

An open-label study in China suggested that the molecules could help prevent healthy people from getting infected. On July 20, the British pharmaceutical company Synairgen announced that an inhaled form of interferon called SNG001 lowered the risk of severe Covid-19 in infected patients in a small clinical trial. The full data have not yet been released to the public, or published in a scientific journal. On August 6, the National Institute of Allergy and Infectious Diseases launched a Phase III trial on a combination of Rebif and the antiviral remdesivir, with results expected by fall 2020.Updated Aug. 10

The most severe symptoms of Covid-19 are the result of the immune systems overreaction to the virus. Scientists are testing drugs that can rein in its attack.

PROMISING EVIDENCE EVIDENCE IN HUMANS DexamethasoneThis cheap and widely available steroid blunts many types of immune responses. Doctors have long used it to treat allergies, asthma and inflammation. In June, it became the first drug shown to reduce Covid-19 deaths. That study of more than 6,000 people, which in July was published in the New England Journal of Medicine, found that dexamethasone reduced deaths by one-third in patients on ventilators, and by one-fifth in patients on oxygen. It may be less likely to help and may even harm patients who are at an earlier stage of Covid-19 infections, however. In its Covid-19 treatment guidelines, the National Institutes of Health recommends only using dexamethasone in patients with COVID-19 who are on a ventilator or are receiving supplemental oxygen.

TENTATIVE OR MIXED EVIDENCE EVIDENCE IN HUMANS Cytokine InhibitorsThe body produces signaling molecules called cytokines to fight off diseases. But manufactured in excess, cytokines can trigger the immune system to wildly overreact to infections, in a process sometimes called a cytokine storm. Researchers have created a number of drugs to halt cytokine storms, and they have proven effective against arthritis and other inflammatory disorders. Some turn off the supply of molecules that launch the production of the cytokines themselves. Others block the receptors on immune cells to which cytokines would normally bind. A few block the cellular messages they send. Depending on how the drugs are formulated, they can block one cytokine at a time, or muffle signals from several at once.

Against the coronavirus, several of these drugs have offered modest help in some trials, but faltered in others. Drug companies Regeneron and Roche drug both recently announced that two drugs called sarilumab and tocilizumab, which both target the cytokine IL-6, did not appear to benefit patients in Phase 3 clinical trials. Many other trials remain underway, several of which combine cytokine inhibitors with other treatments.Updated Aug. 10

TENTATIVE OR MIXED EVIDENCE EVIDENCE IN HUMANS EMERGENCY USE AUTHORIZATIONBlood filtration systemsThe F.D.A. has granted emergency use authorization to several devices that filter cytokines from the blood in an attempt to cool cytokine storms. One machine, called Cytosorb, can reportedly purify a patients entire blood supply about 70 times in a 24-hour period. A small study in March suggested that Cytosorb had helped dozens of severely ill Covid-19 patients in Europe and China, but it was not a randomized clinical trial that could conclusively demonstrate it was effective. A number of studies on blood filtration systems are underway, but experts caution that these devices carry some risks. For example, such filters could remove beneficial components of blood as well, such as vitamins or medications.Updated Aug. 10

TENTATIVE OR MIXED EVIDENCE EVIDENCE IN HUMANS Stem cellsCertain kinds of stem cells can secrete anti-inflammatory molecules. Over the years, researchers have tried to use them as a treatment for cytokine storms, and now dozens of clinical trials are under way to see if they can help patients with Covid-19. But these stem cell treatments havent worked well in the past, and its not clear yet if theyll work against the coronavirus.

Doctors and nurses often administer other supportive treatments to help patients with Covid-19.

WIDELY USEDProne positioningThe simple act of flipping Covid-19 patients onto their bellies opens up the lungs. The maneuver has become commonplace in hospitals around the world since the start of the pandemic. It might help some individuals avoid the need for ventilators entirely. The treatments benefits continue to be tested in a range of clinical trials.

WIDELY USEDEMERGENCY USE AUTHORIZATIONVentilators and other respiratory support devicesDevices that help people breathe are an essential tool in the fight against deadly respiratory illnesses. Some patients do well if they get an extra supply of oxygen through the nose or via a mask connected to an oxygen machine. Patients in severe respiratory distress may need to have a ventilator breathe for them until their lungs heal. Doctors are divided about how long to treat patients with noninvasive oxygen before deciding whether or not they need a ventilator. Not all Covid-19 patients who go on ventilators survive, but the devices are thought to be lifesaving in many cases.

TENTATIVE OR MIXED EVIDENCE EVIDENCE IN HUMANS AnticoagulantsThe coronavirus can invade cells in the lining of blood vessels, leading to tiny clots that can cause strokes and other serious harm. Anticoagulants are commonly used for other conditions, such as heart disease, to slow the formation of clots, and doctors sometimes use them on patients with Covid-19 who have clots. Many clinical trials teasing out this relationship are now underway. Some of these trials are looking at whether giving anticoagulants before any sign of clotting is beneficial.

False claims about Covid-19 cures abound. The F.D.A. maintains a list of more than 80 fraudulent Covid-19 products, and the W.H.O. debunks many myths about the disease.

WARNING: DO NOT DO THISDrinking or injecting bleach and disinfectantsIn April, President Trump suggested that disinfectants such as alcohol or bleach might be effective against the coronavirus if directly injected into the body. His comments were immediately refuted by health professionals and researchers around the world as well as the makers of Lysol and Clorox. Ingesting disinfectant would not only be ineffective against the virus, but also hazardous possibly even deadly. In July, Federal prosecutors charged four Florida men with marketing bleach as a cure for COVID-19.

WARNING: NO EVIDENCEUV lightPresident Trump also speculated about hitting the body with ultraviolet or just very powerful light. Researchers have used UV light to sterilize surfaces, including killing viruses, in carefully managed laboratories. But UV light would not be able to purge the virus from within a sick persons body. This kind of radiation can also damage the skin. Most skin cancers are a result of exposure to the UV rays naturally present in sunlight.

WARNING: NO EVIDENCESilverThe F.D.A. has threatened legal action against a host of people claiming silver-based products are safe and effective against Covid-19 including televangelist Jim Bakker and InfoWars host Alex Jones. Several metals do have natural antimicrobial properties. But products made from them have not been shown to prevent or treat the coronavirus.

Note: After additional discussions with experts we have adjusted several labels on the tracker. The Strong evidence label has been removed until further research identifies treatments that consistently benefit groups of patients infected by the coronavirus. In its place, Promising evidence will be used for drugs such as remdesivir and dexamethasone that have shown promise in at least one randomized controlled trial, and Widely used for treatments such as proning and ventilators that are often used with severely ill patients, including those with Covid-19. And we may reintroduce the Ineffective label when ongoing clinical trials repeatedly end with disappointing results.

Why Silicon Valley Execs Are Investing Billions to Stay Young – Robb Report

By daniellenierenberg

Entrepreneur Dave Aspreys end-of-life plans are quite simple, really, even if some of his ambitions sound laughably optimistic to most of us.I want to die at a time and by a method of my own choosing, and keep doing awesome things until that day, he tells me. I dont think its outrageous to believe Ill make it to 180 years old. And if I run out of energy, itll just be because I did too much cool shit for my own good.

Asprey is strolling across his lush property in British Columbia, holding up his phone and pointing out the specimens in this years garden as we chat over Zoom in the midst of the global pandemic. Hes protecting his skin from the sun with a goofy Outdoor Research hat and wearing a long string of beads that he says are each over a hundred years old, from cultures around the world.

Asprey, 48, is the founder of the Bulletproof wellness empire and a vocal champion of the movement to extend human life expectancy beyond 100 years. Hes made millions by experimenting on his own body and packaging his home-brewed discoveries into books, a podcast, consulting services and consumer products (you may have even tried his butter-laced coffee). Asprey, who was a web-security executive before he became the Bulletproof Executive, is just one of a cadre of tech elite who have begun directing their attentionand truckloads of moneytoward the problem of life extension. Jeff Bezos, Peter Thiel, Sergey Brin, Larry Ellisonname a Silicon Valley A-lister and he or she is likely funding longevity research, experimenting with anti-aging interventions or both. These are the masters of the universe who see no reason they cant take the tech industrys optimization obsession and apply it to the ultimate challenge: conquering death itself.

And their efforts appear to be paying off: Thanks to a recent explosion of advances in longevity medicine, Aspreys vision of living healthfully into his second century might not be so crazy. In fact, for people in middle age right now, a handful of therapies in clinical trials have the potential, for the first time in human history, to radically transform what old age looks like. If the life extensionists are right, a person whos 40 today might reasonably expect to still be downhill skiing, running a 10K or playing singles tennis at 100.

If you do anti-aging right, Asprey insists, youll have a level of resilience and energy to fight what comes your way. If you get Covid-19, youre less likely to become very sick. The idea is that at a cellular level, youre making yourself very hard to kill.

The most extreme of the controversial interventions Asprey has undergone involved having stem cells extracted from his own bone marrow and fat and then injected into hundreds of locations on his body. Into every joint, between every vertebra and into my cerebrospinal fluid, face and sex organs, he tells me cheerfully. For what I spent on that, I could have bought a really nicely appointed Tesla.

He trots up a flight of stairs to his home office, which sits above a million-dollar lab filled with health gadgets, such as a cryochamber, a hypoxic trainer and an AI-enabled stationary bike. For a wealthy person, investing in your body should be a major part of your Im rich strategy, he explains. Personally, I think you should be spending at least 2 to 3 percent of your net worth on health and longevity. Get a personal chef who can cook you the right food. Its not that hard.

It might be an exaggeration to say BioViva CEO Liz Parrish believes death is optional, but for her, Aspreys goal of living to 180 shows a distinct lack of ambition. If you can reach homeostasis in the body, Parrish says, where its regenerating itself just a little bit faster than its degrading, then what do you die of? An accident or natural disaster, probably. Theres no expiration date at 90 or 100 years old.

Tall, blond and fit, Parrish cuts a strikingly youthful figure at 49one that might convince you to order whatever shes having. But, like Asprey, she has received criticism from the longevity research community for becoming patient zero in her own experimental drug trial, aimed at halting aging at the cellular level. In 2015, Parrish underwent telomerase and follistatin gene therapies in Bogota, Colombia. The procedures involved receiving around a hundred injections of a cocktail of genes and a virus modified to deliver those new genes into her bodys cells. The objective was to prevent age-related muscle loss and lengthen her telomeres: the caps at the end of our chromosomes. Scientists have identified their unraveling as not only a marker of aging but also a potential cause of age-related decline.

Liz ParrishLiz Parrish

Parrish told the media about her clandestine experiment and has published periodic updates on her condition in the five years since, and she reports that she has indeed increased her muscle mass and lengthened her telomeres. Parrishs punk-rock approach stems from her conviction that the medical-research communityboth the Food and Drug Administration (FDA) and researchers who arent business-mindedis moving too slowly, with too much red tape, when it comes to advancing aging therapeutics. But gene therapy is a relatively new area of medicine that brings with it a host of new risks, including cancer, severe immune reactions and infections caused by the viral vector used to deliver the drug.

Parrish downplays such worries. There may be risks, she tells Robb Report. But the known risk is that youre 100 percent likely to die. So you have to decide for yourself if the potential benefit outweighs that.

Humans have always aspired to find the fountain of youth, so people might be skeptical about the fact that anti-aging technologies are working now, says British investor and businessman Jim Mellon. But the fact is that this is finally happening, and we need to seize the moment. Mellon cofounded Juvenescence, a three-year-old pharmaceutical company thats investing in multiple technologies simultaneously to increase the odds of bringing winning products to market.

Mellon, 63, has made his fortune betting on well-timed investment opportunities, and he predicts that a new stock-market mania for life extension is just around the corner. This is like the internet dial-up phase of longevity biotech, he enthuses. If youd invested in the internet in the very early days, youd be one of the richest people on the planet. Were at that stage now, so the opportunity for investors is huge. According to a report by Bank of America Merrill Lynch, hes not wrong: The market for technologies to increase human life span is projected to grow sixfold to $610 billion in just the next five years.

When I talk to Mellon in the late spring, hes sequestered on the rugged coast of the Isle of Man, a tiny spit of land in the Irish Sea. Despite being what he describes as imprisoned there for 15 weeksand countingduring the Covid-19 shutdown, hes jovial and chatty and wants to make it clear that his interest in life extension is much more than financial. Working to extend life is an ethical cause, he says. If we can help people to live healthfully until the end of life, well transform the world completely. Well reduce a huge amount of pressure on failing health-care systems, and well have to reimagine pension and life insurance. This should be the number-one tick in anyones investment portfolio.

If youd like to get on board with this social-impact view of longevity, it helps to understand the trajectory of aging today. In Americas most affluent neighborhoods, the average life span is about 88 years. (Meanwhile, in this countrys poorest, it hovers around a meager 66 because of a raft of inequalities, such as diet, stress, smoking, pollution and health care.) For most people, health starts gradually diminishing in the last 15 years of life with the onset of chronic conditions, including arthritis, neurodegeneration and diabetes. If we could eliminate such diseases of aging, experts say, the US could save an estimated $7.1 trillion in health-care costs over the next 50 years. (Quite where all these sprightly centenarians might live on this already densely populated planet remains to be seen.)

Jim MellonEric Verdin

One of Mellons bets is on a class of drugs called senolytics, which destroy senescent cells: the so-called zombie cells that, for complex reasons, stop dividing as we age. Senescent cells harm the body by secreting compounds that cause inflammation in surrounding tissues. Many age-related conditionsarthritis, diabetes, Alzheimers, cancerhave an inflammatory component, and studies suggest that a buildup of senescent cells is a large part of the problem.

A number of biotech start-ups are devel- oping drugs that target cell senescence, but the furthest along is Unity Biotechnology, a company in South San Francisco that has three drugs in clinical trials to address aging conditions, starting with osteoar- thritis of the knee. Unity raised more than $200 million from such big names as Thiel and Bezos, who chipped in through their investment firms, before going public in 2018. Since then, Mellon has also bought a small stake.

The holy grail of senolytics will be the development of a preventive therapy to wipe out senescent cells in the body before they cause conditions of aging, theoretically extending life span. In June, a team from Sloan Kettering published new breakthrough research showing that CAR T cellstypically used for precision cancer therapycan also be used to target and kill senescent cells. Prescription senolytics for anti-aging therapy are still years away, but unsurprisingly, theres an audience of longevity enthusiasts who want to access such anti-aging miracles yesterdayand no shortage of FDA-unapproved ways to chase after them. For instance, after a few studies examined the senolytic effects of a chemotherapy drug called dasatinib, the website FightAging.org published a step-by-step guide to senolytic self-experimentation using chemotherapeutics.

It doesnt take a Ph.D. in biochemistry to guess that taking off-label chemo drugs might come with harmful side effects, but that hasnt stopped a zealous group of body-hackers from trying it themselves and chronicling their efforts online. The internet is littered with novice longevity adviceand sketchy anti-aging companies eager to separate the hopeful and desperate from their money, like the company that charges $8,000 for transfusions of plasma from the blood of teenagers and early-twentysomethings (yes, just like Gavin Belson on HBOs Silicon Valley). Many of these are at best ineffective and at worst deadly, since the same cellular systems that fuel growth in young people might cause cancer when tipped into overdrive. Imagine the tragic irony of paying tens of thousands for a therapy that promises to help you live longer but actually causes the cancer that kills you.

Beyond the obvious red flags of repurposed chemo drugs and the bloodletting of teens, it can be difficult for a layperson to separate the world-changing longevity breakthroughs from the terrible ideas. Enter one of the worlds leading experts on longevity to help make sense of things.

Eric Verdin, 63, is president and CEO of the Buck Institute, a globally renowned center for aging research just outside San Francisco in Marin County. Verdin is bullish on the promise of living healthfully to at least 100. Today. But 180? Dont count on it. My prediction, based on everything we know today, is that getting to 120 is about the best we can do for the foreseeable future. Ill bet my house were not going to see anyone live to 180 for another 200 years, if ever, he says. But making everyone a healthy centenarian, this is something we can do today. And thats something to be excited about.

Verdins own lab at the Buck Institute studies the aging immune system and how its affected by lifestyle factors, such as nutrition and exercise. Informed by this research, Verdin follows a time-restricted diet in which he eats all of his meals in an eight-to-nine-hour window (similar to the Buchinger Wilhelmi process) and gets plenty of exercise mountain biking in Marins steep hills. The good news is that over 90 percent of what causes diseases of aging is environmental, and that means its within your control, he says.

But he emphasizes that responsible management of your health comes with limits, like avoiding experimental therapies. A group of people have decided to try some expensive and dangerous interventions, but there is zero evidence that any of these are going to help them live longer, he says. The problem, according to Verdin, is that the results of aging interventions in mouse trials can look very promising but rarely translate to success in humans. Theres a huge delta between the health of a stressed lab mouse and an optimally healthy mouse, Verdin says. So when you treat lab mice with longevity therapeutics, you see an outsized result that doesnt at all guarantee the same result in humans.

On the other hand, Verdin tells Robb Report, there are definitely new protocols worth getting excited about. Take, for instance, rapalogs, a class of drugs that interact with a protein called mTOR, which serves as a linchpin for multiple critical biological processes, including cell growth and metabolism. Rapalog drugs tamp down mTOR, possibly preventing age-related diseases such as diabetes, stroke and some cancers. The drug rapamycin, the most heavily studied formula, was approved in the US in 1999 to help prevent organ-transplant rejection. Last year the medical journal Aging published a rapturous opinion piece by oncologist Mikhail Blagosklonny in which he made the case that rapamycinin small or intermittent dosesis effective as a preventive treatment to ward off diseases of aging, and that, in the elderly, not taking rapamycin may be even more dangerous than smoking.

Eric VerdinJim Hughes Photography

Later this year, a biotech firm called resTORbio, which was spun out of the Swiss-based Big Pharma company Novartis in 2017, is expected to seek FDA approval for its rapalog RTB101, which clinical trials have shown to slow age-related decline of the immune system and improve immune response in elderly people by more than 20 percent, a key factor in protecting vulnerable aging populations from disease. (It is currently in trials on elderly patients with Covid-19.) This is the furthest-along program of anything in the aging field, Joan Mannick, cofounder and chief medical officer of resTORbio, told MIT Technology Review last year. If health authorities approve this drug well have a product for people to prevent age-related diseases. Not just in our lifetime, but in, you know, a few years.

One of the many effects of rapamycin is that it mimics the mechanisms of calorie restriction. As Verdins lab and others have shown, fasting provides a number of anti-aging benefits, including insulin regulation, reduced inflammation and, to put it colloquially, clearing out the gunky by-products of metabolismpart of the reason Twitter CEO Jack Dorsey and other tech titans eat just a few meals per week. For lesser mortals, fasting is extremely hard to commit to and not much fun, hence the huge interest in calorie-restriction mimetics like rapamycin, which provide all the benefits without the downer not-eating part.

Of all the calorie-restriction mimetics, the one sparking the most excitement among longevity researchers is already on the market: metformin, a decades-old diabetes drug. Metformin became a part of the Silicon Valley health regimen several years ago after an epidemiological study showed that Type 2 diabetics who took the drug lived longer than non-diabetics who didnt. Just about everyone in the longevity industry takes metformin, Verdin tells me. He takes it himself, and nearly everybody I interviewed is taking or has taken it, too.

In April, Nir Barzilai, the renowned endocrinologist who spearheaded research on the anti-aging properties of metformin, announced in an opinion piece he co-authored in the journal Cell Metabolism that his lab is launching a large clinical trial to investigate the anti-aging effects of the drug on non-diabetic populations. Barzilais goal is to prove to the FDA that aging itselfrather than conditions associated with it, like Alzheimers and arthritiscan be targeted as a disease. If Barzilai is successful and the FDA approves aging as a treatment indication, the process of bringing longevity therapies to market would accelerate rapidly.

Just as the FDA was able to move faster to bring Covid-19 therapies to market this year, we will reach a tipping point when public opinion pushes the FDA to approve aging as an indication, and the longevity-research field will make leaps as a result, Mellon says. He has contributed funding to Barzilais metformin research, which he believes will be instrumental in proving that there are compounds that can extend human life across the board.

The fact of the matter is that the US has the best regulatory system for new drug development in the world, Mellon says. Were in the first era ever when humans can be bioengineered to live longer. And in 10 years, well have solutions that are even better than today. Just wait, its coming.

15 Best Face Moisturizers With SPF 2020 – Moisturizer With Sunscreen – Women’s Health

By daniellenierenberg

Since sunscreen should be applied every dayyes, every daywhy not consolidate steps by using a sunscreen/moisturizer hybrid? The hydrating formulas give you the benefits of sun protection without the white, streaky aftermath. Plus, it makes it that much easier to apply (aka no more excuses about forgetting to put on sunscreen). Look for moisturizing ingredients like hyaluronic acid, ceramides, or niacinamide that give your skin a drink without leaving it greasy.

And if you're still in the camp of "my skin doesn't get burned," that's not an excuse to skip daily SPF. According to The Skin Cancer Foundation, "no matter your skin type, UV radiation from the sun and other sources can cause dangerous, lasting damage to your skin." Sunscreen isn't just about protecting your skin from a sunburn; it also reduces your risk of developing squamous cell carcinoma (the second most common type of skin cancer) by about 40 percent (again, according to The Skin Cancer Foundation) and lowers your melanoma risk by 50 percent. And if it's aging you're worried about, it has your skin covered there too as it prevents wrinkles, sagging, and age spots as well.

Ghostly white cast turning you off? Say hello to tinted sunscreen! (Keep reading for some favorites.)

To get all these benefits of SPF, you have to make sure you're wearing it correctly: Just remember, you need at least a nickel-size drop of sunscreen or SPF moisturizer to cover your face every morning," says Mona Gohara, MD, dermatologist and Women's Health advisory board member.

Here are the 15 best moisturizers with SPF that you won't mind applying every. Single. Day.

You would never know this natural sunscreen houses a whopping 20% zinc oxide thanks to the blendable tint. (Read: You will not mind applying this every day.) You'll also get antioxidant protection thanks to algae and sunflower sprout extract.

This oil-free, lightweight moisturizer blends right in so fast you'll forget if you even applied it. And if you don't want to listen to WH about wearing sunscreen, maybe you'll take a page out of Rihanna's book: You gotta protect your skin from the sun no matter what your skin color is" she says on the Fenty site. "If you have discoloration, guess what, you can get that from the sun. I think a lot of people with darker skin tones think because theyre not burning that they dont need SPF but we can still get sun damage."

Fenty Skin HYDRA VIZOR INVISIBLE MOISTURIZER SPF 30

Whether you have oily skin or you just prefer a lighter consistency, this lotion will be your new fave. It soaks into skin quickly and is basically weightless after it's been appliedyou might even forget you have it onmaking it ideal for layering. Plus, it's non-comedogenic so acne-prone folks won't have to worry.

Simple Skincare, Protecting Light Moisturizer, SPF 15

Made by Black women for Black women, you can trust that this sunscreen/moisturizer hybrid isn't going to leave any white streaks behind. Avocado, jojoba, and sunflower oil all contribute to the rich, hydrating texture that sinks in without clogging pores or leading to breakouts.

Black Girl Sunscreen SPF 30

$18.99

If you're prone to an oily T-zone, this hydrating sunscreen is for you. Ceramides and niacinamide nourish your skin without making it feel greasy, and the mineral SPF ingredients (it contains both titanium dioxide and zinc oxide) keep you sun safe.

CeraVe Hydrating Sunscreen SPF 50 Face

Moisturizing gold standard hyaluronic acid is paired alongside coconut oil and aloe vera for a refreshing and hydrating formula. And thanks to the tint (there's four shades to choose from), it'll even out your complexion too.

Suntegrity 5-in-1 Tinted Moisturizing Face Sunscreen

Most derms recommend a combination of sunscreen and an antioxidant product (to fight aging free radical damage from UV exposure) for the best daily protection. This lightweight lotion has it all in one. It hydrates, has SPF 30, and contains a combination of blackberry extract and vitamins C and E for an antioxidant boost.

Aveeno Absolutely Ageless Daily Moisturizer SPF 30

Hate the feeling of thick, greasy sunscreen? Meet the complete opposite. This gel sunscreen hydrates (thanks to hyaluronic acid, glycerin, and vitamin E) and protects (thanks to a combo of proven chemical sunscreen ingredients) all while feeling like nothing on your skin.

Neutrogena Hydro Boost Water Gel Lotion SPF 50

This triple threat corrects redness, moisturizes, and protects your skin from UV damage. Centella asiatica (an herb native to Asia) is the hero ingredient that works to protect the skin from environmental stress that can lead to irritated, inflamed skin. While the cream goes on green, it quickly turns into a neutral shade to blend into your skin tone for a more even complexion.

Cicapair Tiger Grass Color Correcting Treatment SPF 30

$18.00

Yes, this is a moisturizer with sunscreen, but if you couldn't tell from the name, it's also packed with plant stem cells (they actually make up 15.5 percent of the formula) that fight free radicals to prevent collagen breakdown, promote firmer looking skin, and help smooth fine lines.

Plant Stem Cell Day Cream SPF 30

$75.00

Ever feel like your sunscreen is leaving your skin looking like an oil slick? Meet your new SPF BFF. Not only does it protect your skin from UVA (what causes aging) and UVB (what causes your skin to burn) rays, it also claims to minimize pores by 54 percent and keeps your skin matte for up to 10 hours.

Oil and Pore Control Mattifier Broad Spectrum SPF 45 PA++++

The combo of chemical sun protection ingredients (avobenzone, homosalate, and octisalate) in this nourishing cream provide your skin safety from UVA and UVB rays. It also contains cerium, a mineral that protects from the blue of your computer screen, television, and phone. So, you're double protected.

Supergoop! Superscreen Daily Moisturizer Broad Spectrum SPF 40 PA+++

Think of this moisturizer with sunscreen like a cup of coffee for your skin. While it protects and nourishes, it also boosts your skin's energy from actual coffee beans (the caffeine is also an anti-irritant). Because who couldn't use a extra jolt in the morning?

Origins Ginzing SPF 40 Energy-Boosting Tinted Moisturizer

Extra oily skin types, meet the moisturizer-SPF face cream that will not leave you looking like a greaseball. It has a whipped texture that absorbs in seconds and leaves a velvety smooth finish that looks great under makeup.

Olay Total Effects Whip Face Moisturizer SPF 25

If you're starting to see hyperpigmentation, then you need to up your SPF game. Stat with a brightening product like L'Oral's. This sunscreen lotion contains SPF 30 to stop new dark spots from forming and a combination of glycolic acid, vitamin C, and retinol to treat any existing discoloration.

L'Oral Paris RevitaLift Bright Reveal Brightening Day Moisturizer SPF 30

High-throughput 3D screening for differentiation of hPSC-derived cell therapy candidates – Science Advances

By daniellenierenberg

Abstract

The emergence of several cell therapy candidates in the clinic is an encouraging sign for human diseases/disorders that currently have no effective treatment; however, scalable production of these cell therapies has become a bottleneck. To overcome this barrier, three-dimensional (3D) cell culture strategies have been considered for enhanced cell production. Here, we demonstrate a high-throughput 3D culture platform used to systematically screen 1200 culture conditions with varying doses, durations, dynamics, and combinations of signaling cues to derive oligodendrocyte progenitor cells and midbrain dopaminergic neurons from human pluripotent stem cells (hPSCs). Statistical models of the robust dataset reveal previously unidentified patterns about cell competence to Wnt, retinoic acid, and sonic hedgehog signals, and their interactions, which may offer insights into the combinatorial roles these signals play in human central nervous system development. These insights can be harnessed to optimize production of hPSC-derived cell replacement therapies for a range of neurological indications.

Stem cellsincluding adult and pluripotent subtypesoffer tremendous clinical promise for the treatment of a variety of degenerative diseases, as these cells have the capacity to self-renew indefinitely, mature into functional cell types, and thereby serve as a source of cell replacement therapies (CRTs). Human pluripotent stem cells (hPSCs) are of increasing interest for the development of CRTs due to their capacity to differentiate into all cell types in an adult, for which adult tissuespecific stem cells may, in some cases, not exist or may be difficult to isolate or propagate (1). For example, one potential CRT enabled by hPSCs is the treatment of spinal cord injury (SCI) with oligodendrocyte progenitor cells (OPCs). These hPSC-OPCs have recently advanced to a phase 2 clinical trial for the treatment of SCI (2) and are being considered for additional myelin-associated disorders in the central nervous system (CNS), including adrenoleukodystrophy, multiple sclerosis (3, 4), and radiation therapyinduced injury (5). In parallel, hPSC-derived midbrain dopaminergic (mDA) neurons are under consideration for Parkinsons disease therapy (6, 7).

The promise of hPSC-derived therapeutics such as hPSC-OPCs or mDA neurons motivates the development of manufacturing processes to accommodate the potential associated clinical need. For example, approximately 250,000 patients in the United States suffer from some form of SCI, with an estimated annual incidence of 15,000 new patients (8). Human clinical trials involving hPSC-OPCs have used dosages of 20 million cells per patient (9), such that the hypothetical demand would be over 1 trillion differentiated OPCs. It is therefore imperative to develop systems to enable discovery of efficient and scalable differentiation protocols for these therapies.

Differentiation protocols to direct hPSCs into functional OPCs (10, 11) have been developed to approximate the signaling environment at precise positions within the developing spinal cord. Positional identity of cells is guided patterning cues that form intersecting gradients along the dorsoventral axis, such as Sonic hedgehog (SHH), and rostrocaudal axis, such as retinoic acid (RA). In addition, certain cues are present along both axes, such as Wnts (1215). These signaling environments vary over time as the embryo develops (16, 17). However, translating this complex developmental biology to an in vitro culture requires optimization of a large combinatorial parameter space of signaling factor identities, doses, durations, dynamics, and combinations over many weeks to achieve efficient yield of the target cell type, and there remains open questions about the impact of cross-talk between patterning cues on the expression of cellular markers present in OPCs such as transcription factors Olig2 and Nkx2.2 (18). Strategies to derive OPCs and other potential CRTs from hPSCs have shown steady progress, especially with application of high-throughput screening technology (1921); however, current production systems for hPSC-derived CRTs involve two-dimensional (2D) culture formats that are challenging to scale (2228).

More recently, 3D culture systems have demonstrated strong potential for a larger scale and higher yield (29) of hPSC expansion and differentiation than 2D counterparts, as well as compatibility with good manufacturing practice (GMP) standards (3033). While high-throughput systems for screening 3D cell culture environments have been applied to basic biological studies of hPSC proliferation (34), we envision that this technology could additionally be applied toward systematically optimizing production strategies for CRTs to accelerate the pace of their discovery and development toward the clinic while simultaneously uncovering new interactions among signaling cues that affect cell fate. Here, we harness the powerful capabilities of a uniquely structured microculture platform (35, 36), to screen dosage, duration, dynamics, and combinations of several cellular signaling factors in 3D for hPSC differentiation (Fig. 1). The independent control of gel-encapsulated cells (on pillar chip) and media (in well chip) enables simultaneous media replenishment for more than 500 independent microcultures in a single chip. Furthermore, we use custom hPSC reporter cell lines (37) to enable live imaging of proliferation and differentiation of OPCs for over 80 days on the microculture chip. One thousand two hundred combinatorial culture conditions, amounting to 4800 independent samples, were screened while consuming less than 0.2% of the reagent volumes of a corresponding 96-well plate format. Furthermore, the robust dataset enabled statistical modeling to identify relative differentiation sensitivities to, and interactions between, various cell culture parameters in an unbiased manner. Last, we demonstrate the generalizability of the platform by applying it toward a screen for differentiation of tyrosine hydroxylaseexpressing dopaminergic neurons from hPSCs.

One hundred nanoliters of hPSCs suspended in a hydrogel is automatically dispensed onto the micropillars, and 800 nl of media is automatically dispensed into the microwells by a robotic liquid handling robot programmed to dispense in custom patterns. The independent substrate for cells and media enables screens of combinations of soluble cues at various dosages and timings. Scale bar, 1 mm. (B) Timeline of exogenous signals for in vitro 3D OPC differentiation from hPSCs and anticipated cellular marker expression along various differentiation stages.

Initially, we assessed whether hPSCs could be dispensed in the microculture platform system uniformly and with high viability. Quantification of total, live, and dead cell counts across the microchip indicates uniform culture seeding and cell viability at the initiation of an experiment (fig. S1).

We then used a custom-made Nkx2.2-Cre H9 reporter line, which constitutively expresses DsRed protein but switches to green fluorescent protein (GFP) expression upon exposure to Cre recombinase, to longitudinally monitor proliferation and differentiation of hPSCs to Nkx2.2+ oligodendrocyte progenitors in 3D on the microchip platform. A small range of culture conditions from previously published protocols of OPC differentiation were selected for an initial, pilot differentiation experiment, and the GFP expression was quantified after 21 days of differentiation. Cell morphology changes accompanying neural lineage commitment and maturation were clearly observed at later stages in the 3D differentiation (movie S1 and fig. S2) as cultures were maintained and monitored for up to 80 days on the microchip. We then developed fluorescence image analysis pipelines for quantification of nuclear and cytoplasmic marker expression via immunocytochemistry for endpoint analyses at various times (fig. S3). Together, these results support the robust and long-term culture potential and cellular marker expression readout of this miniaturization methodology for hPSC differentiation screening.

hPSC seeding density. We first focused on parameters within the first week of 3D differentiation into OPCs (Fig. 2A). The importance of autocrine, paracrine, and juxtacrine signaling mechanisms among cells in many systems led us to anticipate that the density of cells at the start of differentiation could affect the early neural induction efficiency and, consequently, the efficiency of OPC differentiation. We therefore demonstrated the ability of this microculture platform to test a range of initial hPSC seeding densities on day 2 (fig. S1) and assessed the effect of seeding density on Olig2 expression. We observed notable differences in levels of cell-to-cell adhesion in hPSC cultures by day 0, 2 days after initial seeding (Fig. 2Bi). Then, after 15 days of differentiation, we observed a trend that lower hPSC seeding density, between 10 and 50 cells per pillar, increased OPC specification slightly (Fig. 2Bii).

Timing of SMAD inhibition relative to RA and Wnt signals. The formation of the neural tube in human development (12) results from cells in the epiblast being exposed to precisely timed developmental signals such as Wnt (38) and RA that then instruct neural subtype specification (39). This led us to hypothesize that the overall differentiation efficiency of hPSCs to OPCs in this 3D context in vitro would be sensitive to the timing at which RA and Wnt signals were introduced during neural induction. Therefore, we induced neuroectodermal differentiation of hPSCs via inhibition of bone morphogenetic protein (BMP) signaling using the dual SMAD inhibition approach (40), with LDN193189 (hereafter referred to as LDN) and SB431542 (hereafter referred to as SB), and tested a range of times (0, 2, and 4 days) at which RA and Wnt signals (by CHIR99021, hereafter referred to as CHIR) were introduced into the culture. We observed a strong correlation between early addition of RA/CHIR and OPC specification such that combined exposure of RA and CHIR signals with SMAD inhibition on day 0 resulted in up to sixfold higher Olig2 expression in some cases (fig. S4), potentially implicating an important role of synchronized exposure of RA and CHIR signals with SMAD inhibition for specifying Olig2+ progenitors. For subsequent experiments, we kept the timing of RA and CHIR addition at day 0 and evaluated how the dose and duration of these signals may affect Olig2+ specification.

Dose and duration of key signaling agonists. We examined the combinatorial and temporal effects of three signaling cues that form gradients across intersecting developmental axes in the neural tube to influence specification of oligodendrocyte progenitors: RA (present along the rostrocaudal axis of the CNS development), SHH (41) (a morphogen that patterns the dorsoventral axis of the developing CNS and is activated by smoothened agonist, hereafter referred to as SAG), and Wnt (present along both the rostrocaudal and dorsoventral axes). Because OPC specification is likely sensitive to the relative concentrations of these cues, for example, given the importance of morphogen gradients in oligodendrocyte differentiation in the developing neural tube (12), we assessed the Olig2 expression resulting from a full factorial combinatorial screen of these cues (fig. S5). Most notably, we observed positive correlations in Olig2 expression in response to increasing RA dose and increasing duration of CHIR exposure from days 0 to 4 of differentiation (Fig. 2C). Without CHIR, an increase in RA from 10 to 1000 nM resulted in a 10-fold increase of Olig2 expression by day 21. A similar 10-fold increase in Olig2 expression was observed at an RA concentration of 100 nM if CHIR was present for the first 3 days of differentiation (Fig. 2C). Analysis of variance (ANOVA) analysis revealed a strong effect size for RA when added early in the differentiation, as well as an interaction between RA dose and longer CHIR duration, in specifying Olig2+ cells in this 3D context (fig. S5), consistent with previous work conducted in 2D in vitro formats (19, 42).

In other developmental systems, the activity of the Wnt signaling pathway was observed to be biphasic (43), whereby activation of the pathway initially enhances cardiac development but later represses it. As this complex signaling profile has been applied to enhance cardiomyocyte differentiation protocols in vitro (44), we analogously investigated whether adding antagonists of key signaling pathways after pathway activation could further enhance the OPC differentiation efficiency by adjusting the dorsoventral and rostrocaudal positioning in vitro. Maintaining the 5 M CHIR for days 0 to 3 from the previous experiment, we used IWP-2 (an inhibitor of the Wnt pathway), GANTT61 (an antagonist of SHH signaling), and DAPT (a Notch pathway antagonist) (Fig. 3A) to inhibit endogenous autocrine/paracrine and/or basal signaling. We used a full factorial analysis of these cues to additionally probe for combinatorial interactions among the pathway inhibitors.

Immunocytochemistry images of costained Olig2 (red) and Nkx2.2 (green) cells. Scale bar, 100 m. Error bars represent 95% confidence intervals from four technical replicates.

To further refine the markers for OPC specification, we measured Nkx2.2 expression in addition to Olig2 and quantified the proportion of cells coexpressing both OPC markers. Most notably, a significant decrease in %Olig2 was observed in response to Notch inhibitor DAPT across all conditions tested (Fig. 3Bi). The same trend was not observed with respect to %Nkx2.2. This result could point to a role for Notch signaling in maintaining or promoting specification of Olig2+ progenitorsa hypothesis not previously examined to our knowledgeand serves as preliminary evidence to test Notch agonists such as DLL-4 in follow-up studies of OPC optimization. This effect may be mediated by an interaction with the SHH pathway (45).

A slight increase in %Olig2+ cells was detected with increasing Wnt inhibitor IWP-2 dose when no SHH inhibitor GANTT61 was present, as was a slight increase in %Nkx2.2+ cells as a function of increasing IWP-2 and GANTT61 dose, pointing to a potential interaction between these two cues in inducing Nkx2.2 expression. The highest proportion of Olig2+Nkx2.2+ cells was observed at the highest IWP-2 and GANTT61 doses and was not influenced by DAPT exposure (Fig. 3Bii). As CHIR was present between days 0 and 3 in the differentiation, it seems that the role of Wnt signaling changes during the 21-day differentiation window of hPSCs to OPCs in that initially (days 0 to 3) it promotes OPC differentiation but shifts to an inhibitory role at later stages (days 4 to 21). To examine the extent of reproducibility of these findings, we tested the effect of temporal modulation of Wnt signals in a human induced pluripotent stem cell (hiPSC) line, TCTF, and found that the general trend of activation followed by inactivation of Wnt signaling would increase the proportion of Olig2+ cells at day 21 (fig. S6).

Although the levels of key signaling cues may vary temporally within the natural developmental environment of certain target cell types, such as within the neural tube where a dynamic SHH gradient along the dorsoventral axis patterns pMN development (16, 17), the dosage of signaling cues in the media for in vitro stem cell differentiation protocols is often applied at a constant level throughout the culture period. On the basis of this discrepancy, we applied the micropillar/microwell chip to screen through numerous temporal profiles of SAG, as well as RA due to its analogous role along the rostrocaudal axis during spinal cord development, by dividing the signal window into early and late stages that were dosed independently to form constant, increasing, and decreasing dose profiles over time (Fig. 4A). To gain additional insights into OPC marker expression, we measured Tuj1 expression and calculated the proportion of Olig2+ cells that coexpressed Tuj1 to potentially identify any modulators of the balance between Olig2+ cells that proceed down a motor neuron fate (which are both Olig2+ and Tuj1+) versus an oligodendrocyte fate (Olig2+/Nkx2.2+).

Error bars represent 95% confidence intervals from four technical replicates. *P value < 0.05.

To consider all measured phenotypes simultaneously, we applied a hierarchical cluster analysis from which we were able to identify several patterns. A broad range of endpoint phenotype proportions of Olig2, Nkx2.2, and Tuj1 was found to result from varying the temporal dosing of only two signaling cues, RA and SAG, pointing to a very fine sensitivity to temporal changes in signal exposure in these populations. Four categories of the endpoint marker expression profiles were created to further interpret the cluster analysis. Categories 1 and 2 are composed of phenotypes ranking low on OPC progenitor fate (low Olig2 and/or Nkx2.2 expression), all of which shared the low dosing of RA at 0.1 M between days 2 and 21 of the differentiation, further emphasizing the strong impact of RA on OPC yield. In contrast, category 3composed of the highest Olig2 and Nkx2.2 expression as well as Olig2+Nkx2.2+ proportioncorrelated with the highest dose of early SAG but had negligible differences across doses of late SAG (Fig. 4Biii, and fig. S7). Last, category 4 points to a biphasic relationship of Nkx2.2 expression as a function of RA dosage, where a high dose of RA of 1 M in the late stage of differentiation resulted in lower Nkx2.2 expression (fig. S8) compared with a consistent RA of 0.5 M throughout the entire differentiation. It appears that Olig2 and Nkx2.2 undergo maxima under different RA dosage profiles (fig. S8), and therefore, the use of coexpressing Olig2+Nkx2.2+ cells as the main metric when optimizing OPC differentiation may be most suitable.

We sought a comprehensive, yet concise, analysis to describe individual and combinatorial effects of all 12 culture parameters (e.g., signal agonist and antagonist dosages and timings) on the results of the more than 1000 unique differentiation conditions involved in this study. To this end, we fit generalized linear models to correlate the expression and coexpression of Olig2, Nxk2.2, and Tuj1 to individual input parameters within the 12 culture parameters involved in this study, and the 132 pairwise interactions between them. First, we identified significant parameters of interest for each phenotype measured using a factorial ANOVA (fig. S9). After applying a Benjamini and Hochberg false discovery rate correction for multiple comparisons (46), we fit an ordinary least squares model of the statistically significant terms to the phenotype of interest. The parameter coefficients were analyzed as a measure of relative influence on the expression of a certain endpoint phenotype, such as Olig2+Nkx2.2+ cells, and could be interpreted as a sensitivity analysis of key parameters on the OPC specification process. The most significant parameters were then sorted by their effect magnitude (Fig. 5B).

RA, a rostrocaudal patterning cue, was among the most impactful parameters in this study for Olig2 and Nkx2.2 expression (Fig. 5Bi and ii). In particular, a high RA dose (1 M) early in the differentiation (days 0 and 1) emerged as the most influential culture parameter in the acquisition of OPC fate (coexpression of Olig2 and Nkx2.2) (Fig. 5Bi to iii). In addition, the dose of SAG from days 4 to 10 of differentiation exerted a markedly more significant impact on OPC fate induction than from days 10 to 21 of differentiation, in line with the previous analysis (Fig. 4). IWP-2 and GANT were observed to correlate positively with coexpression of Olig2 and Nkx2.2 as well. Furthermore, this analysis identified two cases of culture parameters interacting in a synergistic manner to promote OPC differentiation. First, higher doses of RA during days 0 to 2 followed by SAG during days 4 to 10 were found to promote higher Nkx2.2 expression. In addition, longer CHIR duration (from days 0 to 4) along with higher GANT dose promoted coexpression of Nkx2.2 and Olig2.

We created a new differentiation protocol from the parameters isolated in this screen to have the most influence in specifying Olig2+Nkx2.2+ progenitors (Fig. 5Biii) and carried out the differentiation into the later stages of OPC maturation in a larger-scale format to assess the ability of this optimized protocol to create mature oligodendrocytes. The protocol was able to produce platelet-derived growth factor receptor (PDGFR)expressing cells by day 60 across multiple hPSC lines, as well as O4-expressing cells by day 75 and myelin basic protein (MBP) expressing cells and myelination ability at day 100 (fig. S10).

The OPC screening identified new conditions that affect cell differentiation, and we then sought to demonstrate the generalizability of this approach by conducting a different study. Specifically, we screened 90 unique hPSC differentiation protocols for tyrosine hydroxylase+ mDA neurons (Fig. 6). Exposure of CHIR was divided into three periods (early, middle, and late), and dosage for each period was varied independently. This screening strategy uncovered a key window of CHIR competence between days 3 and 7 (early), a negligible effect of CHIR between days 8 and 11 (middle), and an inhibitory effect of CHIR between days 12 and 25 (late) of mDA differentiation. These data further illustrate the existence of biphasic signaling activity during the differentiation process and underscore the need to improve the temporal dosing of several signaling agonists across a range of hPSC-derived CRTs.

The clinical emergence of several cell-based therapy candidates (47) is encouraging for human diseases/disorders that currently have no effective small molecule or biologic-based therapy. As research and development into CRT candidates continues to progress, cell production has emerged as a bottleneckas delivery vectors recently have in gene therapyand improved tools will be necessary to enable higher quality and yield in cell manufacturing. Although previous studies have reported ~90% hPSC differentiation efficiency into Olig2+ progenitors using 2D culture formats (19), the 2D culture format constrains the space in which cells can expand to the surface area of the culture plate that limits the overall cell yield that can be produced. The adoption of scalable 3D culture formats, which have demonstrated the ability to produce up to fivefold higher quantities of cells per culture volume, shows promise in surpassing limits of 2D cell expansion (2933) and could result in a higher overall production quantity of target cells even if differentiation efficiencies were lower than what has been reported in 2D. Therefore, the 3D screening and analysis strategy presented here is relevant for numerous emerging CRT candidates for which conversion of a stem or progenitor cell, such as a hPSCs (48), to a therapeutically relevant cell type requires searching through a large in vitro design space of doses, durations, dynamics, and combinations of signaling cues over several weeks of culture.

Notably, to emulate a ubiquitous and naturally occurring phenomenon in organismal development (16, 49), we dynamically varied key signaling cues in our screening strategy, tuning dosage over time. These analyses revealed new biological insights into the dynamic process by which cell competence to signals and fate are progressively specified (50). For example, by applying this platform to screen through several dynamic signaling levels simultaneously, we observed that the differentiation toward Nkx2.2+ progenitors is very sensitive to the dose of RA between days 0 and 1 and the dose of SAG between days 4 and 10. After these respective time windows, the effect of each respective signal in producing Nkx2.2+ progenitors is decreased, potentially pointing to a decrease in cellular competence to each of these signals over the course of OPC development. These cases of stage-specific responses to signaling cues, revealed by our screening platform, create a new dimension for future optimization of cell production.

To effectively navigate this enormous parameter space across doses, durations, dynamics, and combinations of signaling cues and resulting differentiation outcomes, we developed a robust sensitivity analysis strategy that can rank effect sizes to reveal which parameters should be the focus of optimization to modulate expression of target markers of interest (49) and, by contrast, which parameters exert minimal impact and can thus be neglected. For example, titration of RA dose will exert a significantly higher impact on differentiation efficiency than several other culture parameters combined. Furthermore, insights from this study could reduce the necessary quantity of SHH agonist by more than 50% to achieve similar levels of OPC differentiation. As these cell production processes translate from bench scale to industrial scale, awareness of key parameters that influence critical quality attributes (18) of the cell therapy product (such as expression of specific cellular markers) will be a necessary step in reliably producing these therapeutic cell types at scale for the clinic (51).

The wealth of combinatorial and temporal signaling patterns identified in this study can be analyzed in the context of CNS development as well. We observed a potential case of biphasic activity for the Wnt signaling pathway as both activation and inhibition appeared to increase expression of OPC markers Nkx2.2 and Olig2. In particular, this effect was seen with initial Wnt activation by CHIR during days 0 to 3 of OPC differentiation followed by inhibition by IWP-2 during days 4 to 21 of OPC differentiation. The Wnt pathway has shown stage-specific activity in cardiac and hematopoietic development (43, 44), which may thus be a conserved feature across several developmental systems. Wnt signals play an important role in the gastrulation of the embryo to form the primitive streak (38), yet in the subsequent stages of spinal cord development, Wnt signals induce a dorsalizing effect (52), whereas oligodendrocytes originate from the motor neuron domain on the ventral side. Therefore, suppressing endogenous Wnt signals in vitro after initial activation of Wnt may better recapitulate the natural developmental signaling environment of developing oligodendrocytes. Alternatively, as Wnt signals also play a role in rostrocaudal patterning of the CNS, these insights may further point toward a rostrocaudal region of the CNS during this developmental window that is optimal to recapitulate in vitro for OPC production. The oligodendrocytes created through this protocol, which expressed OTX2 at day 10 (fig. S2C), may resemble OPCs in the midbrain/hindbrain region. It is conceivable that exposure to the Wnt antagonist, IWP-2, induced a position rostral to the spinal cord during the differentiation window. This biphasic Wnt trend was seen again in our analysis of differentiation of mDA neurons, underscoring that stage-specific responses may be a conserved feature across several differentiation processes aiming to recapitulate a precise cellular position across several axes of patterning signals during natural development.

Furthermore, the statistical model identified an interaction between RA and SAG (an SHH agonist) in the early differentiation windows for specifying Nkx2.2+ progenitors (Fig. 5B), which has not been previously reported to our knowledge. In the developing CNS, RA signaling influences rostrocaudal positional identity, whereas SHH signaling specifies dorsoventral positional identity. Therefore, this statistical interaction found in the screen may represent intracellular cross-talk between the RA and SHH signaling pathways to integrate both patterning dimensions into Nkx2.2+ progenitor identity. This finding builds on what is known about RA and SHH signals for Olig2+ progenitor development in the spinal cord (53, 54).

Additionally, the 3D context of this screening platform enables high-throughput investigation into neurodevelopmental model systems that can offer unique perspectives beyond what is capable in 2D screening platforms, for example, by recapitulating cell-to-cell interactions, cytoskeletal arrangement, and multicellular patterning in 3D. The lumen structures that were observed during the neural induction period (fig. S2B and movie S1) in response to caudalizing conditions (high Wnt and RA) could be the basis of future organoid screening strategies to probe early multicellular arrangement and the effect of lumen size and shape on cell fate determination at various positions along the rostrocaudal and dorsoventral axes.

In conclusion, we demonstrate the versatile capabilities of a unique microculture platform for 3D differentiation screening and optimization of hPSC-derived cell therapies, whereby 1200 unique OPC differentiation timelines, and a total of over 4800 independent samples, were investigated using 0.2% of the reagent volumes required in a standard 96-well plate format. The dense dataset enabled subsequent statistical modeling for empirical optimization of the differentiation process and identified differential sensitivities to various culture parameters across time. These insights are important in developing strong process knowledge for manufacturing stem cell therapeutics as they continue to emerge in the clinic, and therefore, such screening strategies may accelerate the pace of discovery and development. Simultaneously, this combinatorial 3D hPSC differentiation screens may provide new insights on the basic biology of human development.

Human embryonic stem cells (H9s: National Institutes of Health Stem Cell Registry no. 0062) and hiPSCs (TCTFs: 8FLVY6C2, a gift from S. Li) were subcultured in monolayer format on a layer of 1% Matrigel and maintained in Essential 8 medium during expansion. At 80% confluency, H9s were passaged using Versene solution and replated at a 1:8 split.

H9s were dissociated into single cells using Accutase solution and resuspended in Essential 8 medium containing 10 M Y-27632 (ROCK Inhibitor). H9s were counted and resuspended at defined densities in 50% Matrigel solution on ice. While chilled, 100 nl of H9s in 50% Matrigel solution was deposited onto the micropillars at a density of 100 cells per pillar, unless otherwise noted, using a custom robotic liquid handling program and then incubated at 37C for 20 min to promote gelation of 3D cultures. The micropillar chip was then inverted and placed into a fresh microwell chip containing cell culture media (table S1). All liquid dispensing into the microculture platform was performed with a DIGILAB OmniGrid Micro liquid handler with customized programs for deposition patterns. Between days 2 and 0, cells were kept in E8 media supplemented with 10 M ROCK Inhibitor. Between days 0 and 10, cells were kept in differentiation media made of a base of 50% Dulbeccos Modified Eagles MediumF12, 50% Neurobasal, 0.5% penicillin/streptomycin (pen/strep), 1:100 GlutaMAX supplement, 1:50 B27 supplement, and 1:50 N2 supplement. Between days 10 and 21, cells were kept in differentiation media made of a base of 100% Neurobasal, 0.5% pen/strep, 1:100 GlutaMAX supplement, 1:50 B27 supplement, and 1:50 N2 supplement. After day 21, OPCs were transitioned to maturation media consisting of 100% Neurobasal, 0.5% pen/strep, 1:100 GlutaMAX supplement, 1:50 B27 supplement, 1:50 N2 supplement, insulin-like growth factor 1 (10 ng/ml), platelet-derived growth factor (PDGF)AA (10 ng/ml), NT-3 (10 ng/ml), and insulin (25 g/ml). Media were changed daily by transferring the micropillar chip into a microwell chip containing fresh media every other day using a custom-made mechanical Chip Swapper for consistent transfer. Technical replicates included two different dispensing patterns to average out positional effects across the microchip.

At the endpoint of the experiment, the micropillar chip was carefully removed from the microwell chip and placed in new microwell chip containing calcein AM, ethidium homodimer, and Hoechst diluted in sterile phosphate-buffered saline (PBS) (dilution details in table S1). The micropillar chip was incubated for 20 min and then transferred to a new microwell chip containing PBS, and individual microenvironments were imaged using fluorescence microscopy.

At the endpoint of the experiment, the micropillar chip was carefully removed from the wellchip and placed into a bath of 4% paraformaldehyde for 15 min to fix cell cultures. Then, the micropillar chip was washed twice in PBS for 5 min each and placed into a bath of 0.25% Triton X-100 + 5% donkey serum in PBS for 10 min to permeabilize cells. After permeabilization, the micropillar chip was washed five times in 5% donkey serum for 5 min each, transferred to a wellchip containing primary antibodies of interest diluted in PBS + donkey serum (dilution details in table S1), and stored overnight at 4C. After primary staining, the micropillar chip was washed twice in PBS for 5 min each, placed into a microwell chip containing the corresponding secondary antibodies (dilution details in table S1), and incubated at 37C for 2 hours. After secondary staining, the micropillar chip was washed twice in PBS for 5 min each and placed into a wellchip containing PBS; individual microenvironments were imaged using fluorescence confocal microscopy.

Stained micropillar chips were sealed with a polypropylene film (GeneMate T-2452-1) and imaged with a 20 objective using a Perkin Elmer Opera Phenix automated confocal fluorescence microscope available in the High-Throughput Screening Facility at University of California, Berkeley. Laser exposure time and power were kept constant for a fluorescence channel within an imaging set. Images were scored for marker expression depending on nuclear or cytoplasmic localization (fig. S3).

Fixed cultures on micropillars at day 15 were stained with 4,6-diamidino-2-phenylindole (DAPI) and imaged using an upright Olympus BX51WI microscope (Olympus Corporation) equipped with swept field confocal technology (Bruker) and a Ti:sapphire two-photon Chameleon Ultra II laser (Coherent) was used. The two-photon laser was set to 405 nm, and images were captured using an electron multiplying charge-coupled device camera (Photometrics). Prairie View Software (v. 5.3 U3, Bruker) was used to acquire images, and ImageJ software was used to create a video of the z-series.

Quantified image data were then imported into Python for statistical data analysis (55) and visualization. For comparisons between datasets acquired across different experimental sessions, raw data were scaled and centered by z score, and descriptive statistics were calculated from four technical replicates. Error bars represent 95% confidence intervals, unless otherwise specified. For the hierarchical cluster model, the Euclidean distance was used to measure pairwise distance between each observation, and the unweighted pair group method with arithmetic mean (UPGMA) algorithm was used to calculate the linkage pattern. A Benjamini and Hochberg false discovery rate correction was applied as needed to correct for multiple comparisons. Code is available upon request.

Vida Ventures co-leads Dyne’s $115M megaround for next-gen oligo therapies aimed squarely at muscles – Endpoints News

By daniellenierenberg

Dyne Therapeutics started out last April with a modest $50 million to mine targeted muscle disease therapies from its in-house conjugate technology. The biotech has now convinced more investors that its got gems on its hands, closing $115 million in fresh financing to push its next-gen oligonucleotide drugs into the clinic.

Vida Ventures and Surveyor Capital led the round, joined by a group of other new backers including Wellington Management Company, Logos Capital and Franklin Templeton.

Atlas where Dyne was incubated also returned alongside Forbion and MPM.

Stefan Vitorovic, who co-founded Vida with Arie Belldegrun and others, took the lead on this one. Dynes FORCE platform matches exactly their appetite for bold visions in the future of medicine, with the potential to deliver life-changing outcomes for patients with muscle diseases, he said.

This is how the biotech plans to do it: By linking an antibody to an oligonucleotide, Dynes therapies are engineered to hone in on muscle cells and degrade only disease-causing RNA, thereby avoiding systemic toxicity issues.

Romesh Subramanian, a co-founder of what is now Translate Bio, helped launch the operations as an entrepreneur-in-residence at Atlas. Hes since handed the CEO baton to Joshua Brumm and moved to the CSO post.

When you deliver a naked oligo, very little gets to the muscle, he told C&EN back in 2019.

That means a lack of specificity and potential safety problems for drugs like Sareptas controversial Exondys 51. While Dyne is aiming directly at that market with its Duchenne muscular dystrophy program, its initial focus is on myotonic dystrophy.

Trailing closely is a third therapy for facioscapulohumeral muscular dystrophy, followed by discovery work in the cardiac and metabolic arenas.

How would the approach compare to gene therapies, which are cropping up at Sarepta and other newer players focused on muscle diseases? We didnt get a chance to ask Dyne, which is shying away from interviews this morning perhaps a sign of upcoming plans in a booming biotech IPO market.

Under Braum, Dyne has been on a bit of a hiring spree recently, poaching Susanna High from bluebird to be COO, appointing ex-Celgene exec Daniel Wilson as VP of intellectual property, and scooping Debra Feldman from Sage Therapeutics as head of regulatory.

How Adam Smith Might Have Valued Amazon, Netflix, Tesla, And Tiny Biotechs – Seeking Alpha

By daniellenierenberg

Adam Smith (1723-1790) was not who you think he was. I'm talking about the original Adam Smith who wrote The Wealth of Nations (1776) and spent most of his life in Edinburgh, Scotland. The more recent "Adam Smith" - nom de plume of the late George Goodman who wrote The Money Game (1967) - bears much more resemblance to the Adam Smith you think you know.

The first Adam Smith would have had little interest in stock market wisdom because he regarded himself as a moral philosopher rather than an analyst of markets. In fact, he was not even a capitalist. His works do not include the words "capitalist" or "capitalism" because neither came into use in his lifetime. The first mention of "capitalism" in print was in the 1854 novel The Newcomes by William Makepeace Thackeray, whose father had been involved with the East India Company. Karl Marx, oddly enough, helped popularize the term in his classic Das Kapital (1867). The irony is that if Marx did not quite invent the concept of capitalism, he certainly made the term popular in the process of opposing and bashing it.

No one can know what Adam Smith would have thought about free market capitalism as presently practiced, nor can we guess what he would have thought about the aftermarket in shares which we call "the stock market." The first stock exchanges came into being a couple of years after his death and shares were traded in only a small handful of companies including the still extant Bank of New York (NYSE:BK). Security trading over Smith's lifetime was concerned primarily with credit instruments, the exceptions being one-off exchanges organized by and for the British and Dutch East India Companies. So no capitalism, no market opinions from Adam Smith. Sorry to have to tell you.

The primary interest of Adam Smith was the goal which gave his book its full title - an inquiry into the nature and causes of the wealth of nations, in short, the well-being of the general populace. Counterintuitively paired with this was the self-interest which led tradesmen and the early industrialists to seek profit. He used the term "invisible hand" only three times in his writing and just once in The Wealth of Nations, to wit:

The rich consume little more than the poor, and in spite of their natural selfishness and rapacity, though they mean only their own conveniency, though the sole end which they propose from the labours of all the thousands whom they employ be the gratification of their own vain and insatiable desires, they divide with the poor the produce of all their improvements. They are led by an invisible hand to make nearly the same distribution of the necessaries of life which would have been made, had the earth been divided into equal portions among all its inhabitants, and thus without intending it, without knowing it, advance the interest of the society, and afford means to the multiplication of the species...the beggar, who suns himself by the side of the highway, possesses that security which kings are fighting for."

This is the central core of Adam Smith's thinking. It has always interested me that the ultimate goals of Adam Smith and Karl Marx did not differ greatly. The important difference is that Smith believed in freedom of the market while Marx believed that the solution was the top-down mandate of a command economy. We are familiar at this point with the general course of events in top down economies. The 20th Century resolved that question definitively in favor of Smith's view, which we now call capitalism.

Smith, however, never imagined a world with an after-market of securities measured by such things as price earnings ratios and discounted free cash flow. He would have been astonished at the use of these and other forms of analysis central to modern markets including shares of corporations with thousands of shareholders and many millions of shares. The few larger businesses in his day - a few early industrialists and the enormous East India Companies - did not lend themselves to that kind of analysis.

Does that mean that the thinking of Adam Smith is useless in trying to understand value in the modern financial markets? Not at all. Smith's model of the invisible hand contains a clue as to the way he might have valued companies and their shares. In fact, the view of Adam Smith may take us back to the primary purpose of capital markets which focus on start-ups, IPOs, unicorns, perhaps even SPACs, and all companies in their early stages. Such companies seek capital with which they aspire to bring innovations. They hope to profit by serving the unmet and often unrecognized needs of a body of potential customers.

What Smith saw was the intricate interplay between the needs and desires of customers and the self-interest of a risk-taking capitalist. That is the core transaction of the capitalist system. Without so much as a glance at discounted future cash flow, Smith implicitly understood that for a business the important thing was the population for which a business might add value. The issues for the entrepreneur involve the accuracy of their estimate of that market, the share of that market they might expect to win, the revenues they might expect to receive, and the profit margin they might expect to realize on those revenues.

In short, Adam Smith's thinking may not ordinarily be very helpful in the after-market we call "the stock market" but is central to the universe of young and innovative companies. It is directly connected with the way businesses and customers are conjoined. What a business does for its customers, he implies, provides an outline of its ultimate value. For this reason, I see the conjunction of businesses and customers as potentially useful in thinking about leading companies in the current market, especially for those companies which cannot be analyzed usefully by the standard market metrics of sales, margins, earnings, PE, and discounted cash flow.

In Adam Smith terms, a company should be worth a reasonable return for what it contributes to the greater good of the general populace. This single sentence is at the heart of what I am calling the "Adam Smith Model" of valuation. Does it actually work when trying to value innovative companies? Can one make decisions based on this model? To a large degree I think it is the only really helpful approach in valuing companies driven by new products and concepts.

To show how this sort of analysis might work, I will start with my daughter's portfolio of innovative biotech companies, which she put together in the early days of the pandemic. It is a pretty good model of the kind of thing I have always kept a careful distance from. Her surprising success with this portfolio prompted my own internal debate.

My daughter is a bright young woman who will soon turn 50. She has a doctorate in art history from Penn but retrained as a nurse in order to live in the woods in western Massachusetts and raise her children as a single mom close to nature and away from urban centers. Her life is modeled more on Thoreau's Walden than on Ben Graham's The Intelligent Investor. Despite sitting at my dinner table for seventeen years she remained almost entirely ignorant about financial markets until recently. The after-market in stocks seemed to her insufficiently serious to deserve her attention, which might well have been Adam Smith's view had he lived to see it. I confess to having had similar thoughts myself at times but have suppressed them.

In recent years, however, prompted by the realization that she may one day retire and need an income, she has begun to take an interest in markets. Around the beginning of the COVID-19 crisis (on which she had early insight and much sound advice), she put together without telling me a portfolio of biotech companies. She did this on a very small scale. Over four or five months she is up well over 200%, an amount I have never made in anything like that period. Here's an excerpt from an email she sent me on her portfolio:

Yes, that's why I like leronlimab - CytoDyn (OTCQB:CYDY). It has many uses, a high safety profile (I don't give a second glance to drugs with a low safety profile-anyone could have seen that with hydroxychloroquine, and now dexamethasone-which is a broad-target immunosuppressant, hence will never be a commonly used drug for Covid). Leronlimab has a great safety profile and works with a known mechanism vs. the cytokine storm. Anything good for Covid (or the other viruses that are still around: SARS, MERS and Ebola) must not suppress the immune system as a whole (as do all steroids such as dexamethasone). Leronlimab is targeted at the CCR5 receptor-which makes it effective for coronaviruses as well as cancers and autoimmune disease. Amazing for metastatic cancer, including prostate (though the recent studies are on a hard to treat breast cancer), and probably other untreatable but common cancers. It's going to be great for HIV. It's going to work for host vs graft disease (post-transplants, when we go back to doing them). It also appears to work for NASH (non-alchoholic fatty liver disease, which has increased dramatically in numbers, but is silent in most people until it is at a late stage.) It is the next diabetes.

Mesoblast (MESO):

The next wave of medical advances are going to come through better understanding of immunomodulation. Most if not all diseases-including cardiac disease and diabetes--will come to be understood as inflammatory diseases to be manipulated at the cellular level. We will see more and more of these diseases due to our inflammatory (sedentary, antioxidant-deprived) lifestyle and toxic environment. In any case, I'm interested in the companies who are leading the way in specialized research in immunomodulation. Mesoblast is using stem cell technologies to repair the immune system, and applying that technology to many untreatable diseases.

Avalon GloboCare (AVCO):

Same argument as Mesoblast: multiple technologies, targeted immunotherapy. I'm not so interested in any single technology, but they are partnering on several important technologies (stem cells, diagnostic technologies), with broad implications and clinical uses. They are partnering to develop a nasal vaccine for Covid, but again, I'm not as interested in that particular product, but the broader technology. Nasal vaccines are going to be a winner for many reasons-ease of use, global application, and the fact that we will run short on syringes for other vaccines).

Altimmune (ALT):

Same as above: leader in NASH (non-alcoholic fatty liver disease), nasal vaccine technology

Okay, those are my four picks. Amazing for metastatic cancer, including prostate (though the recent studies are on a hard to treat breast cancer). The others, JNJ, Becton Dickinson, and DaVita, you know."

I love the fact that my daughter comes at investing from an angle so different from mine and with a skill set that does not overlap mine at all. I also love that its method combines brains and a good heart - the assumption that a company is worth the sum of what it contributes to human well being. What I find most intriguing is that her natural way of coming at things aligns so closely with the Adam Smith view. Can growth investing possibly have such a simple foundation?

You will probably have guessed that I have never bought anything like these biotech companies nor used anything resembling this kind of analysis. I do not, and could not possibly, recommend any or all of them. They are well outside my areas of knowledge and expertise. The only counsel I was able to give my daughter included the fact that when buying companies like this you should probably buy a basket of them - something which she had already done, intuitively.

By early July she had tripled her money and was beginning to be worried about what felt to her like an overhyped sector of an overpriced market. This was where she thought my advice might be useful. I laughed and said that she should be giving me financial advice instead of vice versa, but if she was nervous she should probably sell down to her comfort level (she's in a low tax bracket so cap gains aren't a problem). Perhaps she should at least sell down to the point at which she was investing with house money. I added that it was okay to leave a few chips on the table and let her long term bet ride. She agreed and did something close to that.

Her insight had been pretty simple. The value of a company should correspond to the amount of value added via the "invisible hand" to the health, happiness, and well-being of its customers - perhaps even to the general populace. You would start by estimating the size of the market for which it provided a product or service. You would then adjust to take into account the competition for that market and finally the probability of your particular company capturing a major part of that market. Then, and only then, you might begin to make rough estimates as to potential revenues and profit margin. The key correlation is not revenue and profit margin, which are well out in the future, but the value the company is likely to add to society. The payoff in small biotechs like these, if it comes at all, is likely to come in a rush when a large pharma company sees the potential and buys them out, fulfilling the Adam Smith projection of appropriate reward for a large service.

When I started to formulate it this way, I realized that I have missed quite a lot in never owning stocks which might be best measured in this way. This includes not just small biotechs and niche technology startups but also giant current market leaders such as Amazon (AMZN), Netflix (NFLX), and Tesla (TSLA). At every point in the lives of these three companies, I have found that the methods by which I have always valued stocks - things like discounted earnings, dividends, and cash flow - made me unable to put together any reasonable argument for owning them.

Had I finally stumbled upon a valuation model that might provide a rationale for buying them? Up to this point, I have not seen a persuasive methodology for thinking about the value of these companies. Could this simple approach account for their unusually high valuations?

Adam Smith implied that the relationship between a business and the population it served was the invisible force behind what we call capitalism. It takes only a small further step to propose that the population served by a business can also be described as an "asset" owned by that business. In some cases, especially young or innovative companies, it is customers acquired that is the central asset. The idea of a business "owning" its customers is not new. I first read about it in a novel at least fifty years ago when a literary agent retires by essentially selling his customers to a rival - a practice that was apparently commonplace even then.

This customer-based approach seems to be the way the founders of these three market leaders looked at the opportunity. Customers weren't just part of the picture. They were the whole thing. Acquiring customers is what these companies set out to do. Everything else could come later. They were determined to do everything it takes to own the largest number of customers, including running their businesses with negative earnings and free cash flow for a long time. The market caught on to their goals and their prices shot up to the stratosphere.

Amazon, Netflix, and Tesla have always sold at ridiculous multiples of earnings and cash flow, if any, and are ridiculously expensive by pretty much every other traditional measure. When you look at them the way my daughter looks at biotechs, however, the picture changes. You set the standard ratios aside and instead ask: what is the value of these companies if measured by the sum of value they provide in service to their actual and potential customers? The transmission of that value to shareholders is initially as invisible as the invisible hand by which value is distributed to the populace. It is nevertheless reflected in the stock price.

Here's how one might do a broad estimate of value for the three companies:

Today, online commerce saves customers money and precious time," writes Bezos. "Tomorrow, through personalization, online commerce will accelerate the very process of discovery. Amazon.com uses the internet to create real value for its customers and, by doing so, hopes to create an enduring franchise, even in established and large markets.

We believe that a fundamental measure of our success will be the shareholder value we create over the long-term. This value will be a direct result of our ability to extend and solidify our current market leadership position. The stronger our market leadership, the more powerful our economic model.

Because of our emphasis on the long-term, we may make decisions and weigh tradeoffs differently than some companies... We will continue to make investment decisions in light of long-term market leadership considerations rather than short-term profitability considerations or short-term Wall Street reactions...We aren't so bold as to claim that the above is the 'right' investment philosophy, but it's ours, and we would be remiss if we weren't clear in the approach we have taken and will continue to take.

From the beginning, our focus has been on offering our customers compelling value," explained Bezos. "We brought [customers] much more selection than was possible in a physical store (our store would now occupy six football fields), and presented it in a useful, easy-to-search, and easy-to-browse format in a store open 365 days a year, 24 hours a day."

That's Amazon's mission statement summed up in a few paragraphs. The guiding purpose to this business model is positioning yourself to "own" more and more customers. This customer-obsession of Bezos amounts to is a manifesto for innovative companies. The second paragraph flows directly from the core principle of Adam Smith. Get first things first, Bezos is saying, meaning understanding the potential market and seizing it. Profitability and measurements commonly used by Wall Street come later.

Amazon is no longer a young company in chronological age, but the vision embedded in its mission statement is to remain a young company forever. A Day 1 company, as Bezos calls it, is always visionary and entrepreneurial in its thinking. What Bezos is saying to investors is: disregard the numbers used by Wall Street analysts. They are important measures only for Day 2 companies (slow-moving, mature companies in stasis, for which the next stage is death). Keep your eyes on the main thing - the growth of your customer base and a high level of customer satisfaction. Facebook (FB) and Alphabet (GOOG)(GOOGL) were like that in early stages but moved fairly quickly to address the question of how to monetize their users, eventually succeeding and becoming measurable by ordinary metrics. They are now ordinary growth companies with moderately high PEs, at least in context of the current market. Bezos rejected early monetization. Have faith, he said. We will monetize our customer base when we get around to it.

The greatest single risk for Amazon is its increasing size, which makes it difficult to remain nimble and full of energy. At some point, it will face the horror which confronts history's great empires - running out of worlds to conquer. Political constraints may have something to do with that, but pure size is the major burden. Summing it up, I would buy Amazon at something like 50-60% of its present price if nothing had gone wrong in the business in the meantime.

2. Elon Musk somehow manages to top Bezos. His manifesto, much of which comes out in random statements and tweets, is that Tesla will one day produce pretty much every car sold in the US, maybe even the world. At the very least it will be the driving force in a new industry. His business has a powerful technological core, but the rational for it is the prospect of capturing much of the total customer base for vehicles. It currently appears to be priced on the assumption that Musk will succeed in this ambition to a large degree.

Musk is confident that Tesla's technology will become the universal standard and squeeze most of the current auto industry into terminal decline. Its panache stems from great aesthetics and the promise of enlisting his customers in the project of slowing climate change and helping save the world. Tesla, he implies, will almost incidentally become highly profitable, an outcome to which Musk himself seems to be personally indifferent but in which his investors might have some interest. If he is right, Tesla will probably look cheap if bought today or tomorrow at 160 times its current (and first annual) positive earnings.

Like Bezos, Musk would have us remember: we don't care about all that. That's the old valuation model. What we care about is a market of 17 million vehicles sold annually in the US and a number around five times that in the world. That's the scale of customers Elon wants to own. Once that happens, he will bite the bullet and monetize.

To own Tesla at anything like the current price you have to make a few audacious assumptions. You have to believe that vehicles will continue to be bought on very large scale and that the overwhelming number of vehicles sold will become electric within a short period of time. You then have to believe that Tesla will become the company that owns most of the customers and sells most of the vehicles. It's not impossible, but there are obstacles to overcome.

If Ford, GM, Toyota, Honda and others launch a modestly successful counterattack, or the whole market shrinks, you will see the earnings and cash flow multiples of Tesla shares contract in the general direction of the valuations of those "Day 2" companies. In other words, if you are an investor, you don't want Tesla to become just another car company, nor do you want it to be the last giant in an industry that is contracting and possibly dying. If one of those things happens, Tesla, as measured by the Adam Smith premise, is likely to be a disappointing investment. This is very broad brush analysis, but that's the only way to really deal with Tesla, a company quite similar to my daughter's biotechs. The risks for Tesla seem high and hard to calculate. These are the problems routinely faced by innovative companies in their early stages, and you must also pay attention to the risk that Tesla could run out of time to overthrow the industry while the industry still exists in its present form.

3. Netflix is a company I have looked at only recently. Until a few months ago I had never used their product - not once. Entertainment is OK - I'm being entertained by writing this, and I dare to hope that you readers are both entertained and stimulated to further thought by it - but I didn't experience Netflix until a millennial step child and her husband spent some time with us and promptly realized that they couldn't live without it. They put it on a couple of our TVs so that they would have some kiddie movies to bribe their 3-year-old to eat dinner plus an hour of decompressing entertainment for themselves before sleep.

A few months ago my wife and discovered that we still had it, linked somehow to their home two thousand miles away, and it turns out that the shows are pretty good. They turned out to be especially valuable during the lockdown. We had run out of old movies, so we started over with Netflix. I started paying attention to articles on Netflix and ultimately took a look at their numbers.

Egads! They have been unprofitable from day one and their negative cash flow has done nothing but increase. Their costs for content are going up and their competition is mounting. On the other hand, Stranger Things is the kind of nitwit escapism that I found that I like after a long hot day teaching tennis (my wife not so much).

How do I put the two views of Netflix together. In this case, the risks and uncertainties make the stock uninvestable for me. For one thing, I am used to having entertainment piped into me for free (I automatically tune out all ads.) The numbers needed are just too daunting for Netflix, the rising costs for content are worrisome, and ultimate limits in a market now sliced several ways implies limits to growth. I am doubtful that Netflix will ever morph into a company I can measure more conventionally. I'm pretty sure I wouldn't renew if our faraway relatives stopped providing it for free. That's the core of it: I'm a customer of sorts, but they don't really own me. I don't own them either, and am not likely to any time soon.

The outperformance of high growth companies over the last decade and most spectacularly over recent months has naturally invited vigorous debate. The catastrophic dot.com crackup exactly two decades ago has receded sufficiently that alt explanations of market behavior are once again beginning to be proposed in earnest. This article is perhaps one of them but exists within the frame of traditional methods.

The dot.com era which reached its peak in 2000 crashed amidst assertions that eyeballs and clicks were better measures of value than earnings or cash flow. I lived through it as a bystander, listening to fellow fitness enthusiasts in the workout room at my tennis club boast about their portfolios, then noticing their absences one by one as the crisis unfolded. I didn't feel schadenfreude, far from it, only relief that I myself had not been ruined.

Valuations are once again at a point which calls ordinary prudence into question. Are the traditional models of valuation no longer worth using? This was suggested recently by BlackRock quant Jeff Shen who argued here that traditional efforts to solve the "mystery" of value are worthless. The Shen view, by the way, derives from this article by another BlackRock analyst, Gerald T Garvey, published in the prestigious Journal of Portfolio Management. The Garvey article comes down firmly on the growth side of the growth/value debate arguing that "elevated percentage value spreads predict higher risk, not higher returns."

In more down to earth terms, Shen and Garvey are saying that companies whose shares haven't been able to grow in this environment are losing ground and possibly dying, and should be avoided. If a stock goes up a lot it is probably safe because the wisdom of crowds is behind its rise. This is the kind of statement that is true until it isn't. Shen goes on to argue that contemporary investors should look for alt indicators and models such as the happiness of a company's employees. That particular idea didn't exactly blow me away, and neither Bezos nor Musk seem to be proponents of using that principle to focus or drive their businesses.

On the other hand, an effort to measure a company's success in terms of the overall value it provides to its customers does seem to me an interesting way to think about growth companies. Most companies trading in the aftermarket for stocks - by now you know that when I use this awkward but accurate phrase I am referring to the "stock market" - are not high growth companies and are probably best analyzed by traditional measures. Ultimately some form of traditional value measurement must appear within the life-cycle of a successful company.

To Jeff Bezos, the moment when traditional cash measures become important to a company is the day that it wakes up as a Day 2 company, a company that does not attempt to reinvent the world afresh every morning. While such a company may still turn out to be a decent investment, it's important for value investors to pay careful attention to their risk of having their business disrupted by new technologies and methods. This is a fairly straightforward way of thinking about the world we now live in, and I have learned to ask the hard questions about everything I own - even companies with seemingly strong moats.

Disruption is a major theme of the contemporary world, and every thoughtful person would do well to put the world together afresh every morning. Even with an open mind, it's hard to anticipate what hidden risks might cause a company's current defenses to collapse. Because of the incredible speed of change and the prevalence of unsuspected collateral effects, this questioning is important in a way that it has never been in the past. That was the important lesson number two from the dot.com event. Buying the disruptors rarely made fortunes, but not being sufficiently cautious about potential disruptees was a good way to lose a fortune.

For these businesses the Adam Smith Model needs to be turned upside down so that it becomes a story about loss of customers. One of the great anecdotal examples was Bill Gates stunning a 1990s gathering of Buffett's value investor pals by using his knowledge of the digital world to inform them that Eastman Kodak (KODK), then a market stalwart, was "toast." The customer criterion proves its importance when inverted. I was unable to estimate the outcome for Amazon - haven't made a nickel directly by buying it - but it was obvious to me instantly that it was going to be the end of the road for many other retailers, as well as many malls and REITs. The history of Sears Roebuck and Walmart were powerful precedents. The only thing not entirely clear was the time frame, which is proving to be much faster than most people expected.

The astonishing thing was how eagerly investors jumped on the Amazon bandwagon, which has many uncertainties, and how slowly the investor mind adjusted to the knock-on effects, which were far more certain. The key to grasping this quickly, is to focus on customers "owned" but sure to slip away, as in the case of Kodak.

The Adam Smith Model is simply one of the ways of making an estimate concerning what the cumulative value should be somewhere down the road at whatever time the company decides to monetize the cash value of owning its customer base. At that point, it will begin to report profits and cash flow, pay dividends, and buy back shares. Apple (AAPL) may be the best current example of this model. It started paying dividends and buying back shares about a year before its growth began to level off. As the dream of perpetual growth disappeared, investors were rewarded by the cold cash that abundantly flowed.

This is the distant event that Bezos' mission statement grudgingly projects. For Bezos, earnings, dividends, and buybacks are Day 2 concerns, and you get the feeling that he would just as soon not live to see them. Being a Day 2 company, is like living a comfortable and happy life: the great second-best award for those who have given up their aspirations to greatness. So Apple was once an innovative company priced on the basis of the Adam Smith Model and has now normalized into a Day 2 company which can be valued by the traditional tools. Who knows, maybe it has a few positive tricks up its sleeve but relentless regular growth is a thing of the past.

Amazon seems to be on the same general course as Apple, but with ordinary shareholder gratification deferred into a less well defined and more distant future. You just have to wait for it, and at an incredibly low discount rate such as the current Treasury rates you are willing to pay up for the ultimate awards now and wait a long time. This is part of the current market infatuation with rapid and persistent growth. If you project very far into the future, the value may approach infinity, or since that concept no longer exists even in physics, you could approximate it by the difficulty Amazon would have if Amazon's business became the major part of the gross product of the planet.

High valuations in the current market can be partially explained by a number of factors including historically low interest rates and the appeal of the tech leaders during a broad public lockdown. It also true, however, that the most optimistic thinking stems from a gambling mentality which is supported by the famous Petersburg Paradox which has come to bear in their valuations. There are a number of recent articles with varied approaches to this subject, and you can sample them by googling Petersburg Paradox.

The Petersburg Paradox is generally credited to Daniel Bernoulli, who published an article on it in 1738, but is sometimes credited to his cousin Nicolaus Bernoulli who talked about it in a letter written in 1713. It is a simple gambling game that doubles your winnings with each successive throw of tails. Its expected return generates an infinite series of events the probability of which decline by the exponential 1/2 to the N power exactly offsetting the exponential increase in winnings (2 to the N power).

Each successive term is exactly 1. The mathematically expected return is the sum of that infinite number of ones. I suppose that this means you max out when the number in dollars is equal to the number of bits (or Planck units) in the universe.

This series, therefore, produces quite large expectation of winnings despite the fact that the probability of large winnings at any particular future point obviously diminishes enormously and becomes very slight after a few coin tosses. It is famous for the contradiction of the expected total return and the relatively small amount that any reasonable person would be willing to wager on that return. A number of mathematicians have attempted to resolve this contradiction - economist and quant Paul Samuelson having been one of them - but their efforts at refutation have been unsatisfying.

Recent articles have related the Petersburg Paradox to investor expectations for stocks with high and persistent earnings growth. An extremely smart and interesting article was published way back in 1957 by David Durand (The Journal of Finance, Vol 12, No 3, Sep 1957, pp 348-363). Durand explored the problem of valuation for growth stocks including the then relatively new approach of using multiple discount rates at various break points in time. The growth numbers are quaint - annual growth at numbers like 5 and 6.5% - chickenfeed compared to growth rates of modern high tech companies.

Durand related the question of pricing long growth periods to the Petersburg Paradox, addressing the infinity problem and the need to truncate the infinite series at some point. This has a parallel to the problem of valuing current growth companies where it is necessary to consider not only forecasts for future earnings growth rates but also the length of waiting time before cash flows and dividends appear. There's also the question of the interest rate used for discounting, which is now virtually nil but has been very significant at times in the past.

The Adam Smith Model happens to dovetail nicely with the distant outcomes of the Petersburg Paradox coin flip game. The further away the payout is from the present the larger the rewards become when you finally throw heads. It's just that in the case of fast growing but not yet profitable companies, you more or less defer the chance of hitting heads early in order to let the reward build exponentially and have the promise of hitting a very large summative outcome in the future. That's where the thinking of investors in Amazon, Tesla, and Netflix must come from, and it's more or less rational if their estimate of the payoff and the time necessary to achieve it are reasonably accurate. It has been pretty accurate in the case of Apple.

There's just one more thing, of course. What if the estimate of Adam Smith value proves to be outright wrong? What if a tough new competitor with a better technology or improved business model appears? What if competition already in place proves to be more formidable than assumed? Even with Amazon these risks must be taken into account, but with Tesla they should be major concerns, and with Netflix they should be very major concerns.

There could also be exogenous risks such as a major rise in interest rates which would wreck the denominator and greatly reduce the value of a distant payoff. That high denominator, by the way, was what drove price earnings ratios in the 1970s down to the single digits. Returns even a few out years were so heavily discounted that no one wanted to look that far into the future. This sort of thinking served to greatly diminish the appeal of growth stocks.

Innovative companies don't always work out. I thought about that a lot around the year 2000, when I attached a 95% probability to my belief that the investing world had lost its collective mind but reserved a 5% probability I was the one who just didn't get it. The odd thing is that some of the new model dot.coms did, in fact, contribute quite a bit to the general welfare. They made all sorts of businesses more efficient, and at the same time made basic communication for everyone cheaper, faster, and better. This is presumably a good thing. In the end, however, it didn't work out well for shareholders who held on long term.

But there's another question. Did their temporarily outrageous valuations represent a magical mechanism for pulling forward a proper reward for founders and the most nimble shareholders despite the fact that the companies themselves were destined to never ultimately earn any money? In a just version of Adam Smith's invisible handsome reward was certainly owed to the founders and early owners who contributed so much to human well being but the mechanism by which they received it is somewhat murky,

So what if that deferred payoff never comes?

Schopenhauer asked a similar question in his Studies in Pessimism, except that he asked it about death, not a sudden gush of cash flow. Calm down, Schopenhauer argued. Why fear death? If you knew it wasn't the end of things, that you would wake up tomorrow morning feeling fine, you wouldn't worry about it much. What about waking up next week? What about next year? What about five or ten years out? What about a thousand years before you wake up? Ten thousand? What about... never? Would it make a difference?

Schopenhauer's courage in the face of non-being is reflected in the large number of investors who seem unworried about the possible absence of cash returns many years into the future. Once you take the Schopenhauer premise, it doesn't matter if the payoff never arrives. The stock is going up today in anticipation of it. That's all that really matters. Shareholders are happy. You can always cash out at your convenience. What is the future anyway but a dwindling infinite series?

It's really more like heaven than death. Both of my grandmothers believed strongly in its existence, although I can't imagine what they really thought it would be like. It probably didn't matter. In both cases, it sustained them over the course of long and productive lives which they lived with great confidence of a wonderful if not precisely defined eternity. Ignorance was bliss.

A business is its customers. Is it as simple as that? The value of a business is the value of the services provided to its present and prospective customers discounted for the distance in time to monetization of those customers but discounted to reflect the possibility of various things that could happen to reduce or wipe out that future payoff. Both new and rapid growth businesses generally defer that payout further into the future than most businesses, especially if the discounting factor is relatively low.

This model produces huge winners and abject losers. We marvel at the winners when we see them without considering survivor bias. We discard the losers even if they have played a major part in the evolution of the economic world and traded at high prices in optimistic moments along the way. In retrospect we wonder why they once traded at such high prices.

In very young industries such as biotechs, the outcome often leaves losers by the way side and rewards just one or two competitors. One way of thinking about this is that at the outset many such companies own a similar probability of surviving but one or two end up "owning" most of the customers and the cash flow bonanza that will eventually come with them. The probability of winning gradually shrinks for most but rises for the winners. For that reason, my daughter's approach of buying a basket of these companies is probably the best way for investors to participate.

This approach may also be very helpful in evaluating growth companies which are not new but remain at some distance from giving investors serious cash rewards. Here the method for selecting a basket of winners draws upon the kind of broad-brush estimates and calculations used in selecting a basket of small biotechs. If looking closely at Amazon, Tesla, and Netflix doesn't help much, it's important to make and constantly update estimates bearing upon the scale and strength of their "ownership" of customers as well as rough estimates of risks. This broad and approximate approach is how Adam Smith would probably have looked at valuation of companies if he was as interested in profits as we sometimes assume him to have been.

Three Years After Stem Cell Trial for Heart Failure was Abandoned New Evidence Shows it Works – Diagnostic and Interventional Cardiology

By daniellenierenberg

August 4, 2020 - More than three years after a clinical trial was prematurely ended for failing to show progress in healing heart attack scars, the European Heart Journal publishing some surprising results showing that the heart cell treatment does benefit patients.[1]

Data from the ALLSTAR study published Tuesday by the European Heart Journal showed that although infusions of allogeneic cardiac cells (called cardiosphere-derived cells or CDCs) did not appear to shrink the infarct scar after a heart attack, other data from the study show a clear benefit.

Compared with patients who received placebo treatment, patients randomized to receive CDC infusions showed a decrease in the volume of blood in the heart before and after it beats, indicating that the heart had not dilated, as it does progressively in heart failure.

"As it develops heart failure, the heart gets bigger and bigger, like a swelling balloon," said the study's lead author, Raj Makkar, M.D., vice president of cardiovascular innovation and intervention for Cedars-Sinai and the Stephen R. Corday, M.D., chair in interventional cardiology. "One way we can measure the health of a heart is to measure the volume of blood it can hold. The bigger the volume, the more damaged the heart."

The newly analyzed data from the ALLSTAR study, which was sponsored by Capricor Therapeutics, showed that patients given a placebo had hearts that continued to swell, holding larger volumes of blood, while the patients who received CDC infusions had smaller hearts with lower volumes.

The new data results include:

The volume of blood held by the heart was essentially unchanged six months after CDC infusion, but increased by more than a teaspoonful in placebo patients.

A blood protein that measures heart failure severity was reduced in patients who had received CDCs, but not in placebo patients.

The chance that these findings were statistical flukes was only 2 percent.

"To me, these data are very reassuring that there really is therapeutic benefit," said Eduardo Marbn, M.D., Ph.D., executive director of the Smidt Heart Institute. "There is a growing body of evidence that this cell treatment does work."

Results from the earlier CADUCEUS trial, published in The Lancet in 2014, showed that injecting CDCs into the hearts of heart attack survivors significantly reduced infarct size. In 2017, however, the multicenter ALLSTAR study was prematurely halted after six months of data showed no decrease in heart attack scar size, but later analyses revealed the beneficial findings reported here.

"We think we may have chosen the wrong endpoint," said Marbn, the Mark S. Siegel Family Foundation Distinguished Professor, whose discoveries and technologies resulted in CDCs. "This happens in science because you have to design the trial a year or more before you begin, and sometimes you bet on the wrong hors... but that doesnt necessarily mean the therapy is ineffective."

The cells used in the study were CAP-1002, Capricor Therapeutics off-the-shelf, cardiosphere-derived cell (CDC) product candidate. Other clinical trials and case series, in which CDCs were used to treat advanced heart failure, Duchenne Muscular Dystrophy, and COVID-19, also demonstrated positive results. And new studies using CDCs are in the planning stages.

"California is known as the stem cell state, but few technologies being tested in California actually were developed here," said Shlomo Melmed, MB, ChB, executive vice president of Academic Affairs, dean of the Medical Faculty and professor of Medicine. "Increasing evidence-including the results of the large multicenter ALLSTAR trial-validates the potential utility of a cell product which was conceived by a faculty member at Cedars-Sinai, and first tested clinically here."

Read the complete study published by the European Heart Journal.

Disclosures: Except for the cells used in CADUCEUS, the cardiosphere-derived cells used in these studies were derived from donor hearts and provided by Capricor Therapeutics. Marbn developed the process to grow CDCs when he was on the faculty of Johns Hopkins University; the process was further developed at Cedars-Sinai. Capricor has licensed the process from Johns Hopkins and from Cedars-Sinai for clinical and commercial development. Capricor has licensed additional intellectual property from Cedars-Sinai and the University of Rome. Cedars-Sinai and Marbn have financial interests in Capricor.

Re-Stem-Funded Study Targeting Mitochondrial Dysfunction in Aging and Age-Related Diseases Published in Science Advances Journal – Press Release -…

By daniellenierenberg

Aug. 9, 2020 / PRZen / SUZHOU, China -- Re-Stem Biotech (Re-Stem or the Company), a biotechnology firm engaged in the research and development of cell therapies targeting osteoarthritis, spinal cord injury and various cancers recently funded in part a study titled "Solid-phase inclusion as a mechanism for regulating unfolded proteins in the mitochondrial matrix". Researchers at The Johns Hopkins University School of Medicine, led by Rong Li, Ph.D., published their findings in the journal "Science Advances" (view full article here: https://advances.sciencemag.org/content/6/32/eabc7288) The study may provide mechanistic insights for mitochondrial dysfunction observed in aging and age-related diseases.

About Mitochondrial DysfunctionMitochondrial dysfunction is a hallmark of age-related diseases, such as cardiovascular diseases and neurodegenerative diseases. During aging, damaged/unfolded proteins in mitochondria that are failed to be degraded gradually accumulate. In addition, recent evidence suggests that non-mitochondrial proteins constituting pathological aggregates in neurodegenerative diseases also accumulate in mitochondria and cause mitochondrial dysfunction. However, it remains unclear how excessive damaged proteins are managed within mitochondria when known quality control mechanisms become inadequate, and how they contribute to mitochondrial dysfunction during the aging process.

About the StudyThe researchers discovered that excessive unfolded proteins in the mitochondrial matrix are consolidated into novel structures, which they named Deposits of Unfolded Mitochondrial Proteins (DUMP). DUMP formation is an age-dependent process, while accelerated DUMP formation causes mitochondrial dysfunction and premature aging. They found that DUMP formation was not random, but specific in mitochondria near endoplasmic reticulum (ER), another organelle in cells. The contact sites between mitochondria and ER regulate DUMP formation via transferring lipids between two organelles. Via a series of genetic and live-cell imaging studies, researchers identified key enzymes of mitochondrial lipid metabolism that control DUMP formation. Manipulation of these enzymes modulates DUMP formation, therefore, potentially they could be targets for anti-aging or treating age-related diseases.

Scientists say a man with HIV is the first to reach long-term remission without a bone marrow transplant, but their peers are sceptical – Business…

By daniellenierenberg

Brazilian researchers announced that a 36-year-old man in Brazil is HIV-free after receiving a cocktail of antiviral drugs.

If true, this unidentified case, detailed at the medical conference AIDS 2020, would be the first instance of long-term remission from HIV without a stem cell or bone marrow transplant.

But the researchers peers are sceptical, since anti-retroviral therapy, which is used to queel HIV and prevent it from developing into AIDS, has been the standard treatment for all HIV-positive people since the treatment was invented in 1995.

There will be a lot of buzz, a lot of controversy about this part everyones going to be sceptical, HIV researcher Dr. Steve Deeks told the New York Times. Am I sceptical? Of course. Am I intrigued? Absolutely.

According to the research team at the Federal University of So Paulo, the man was diagnosed with HIV in 2012 and began taking the typical antiretroviral drugs.

In 2016, he joined a clinical trial where he was given three additional drugs, including maraviroc and nicotinamide, for 11 months, in an aggressive treatment designed to flush the virus out of his body.

The man returned to the standard anti-retroviral therapy after the trial ended, and stopped taking all anti-retroviral drugs in March 2019. Every three weeks since March 2019, his blood has been tested.

The fact that he tested negative for HIV is not remarkable in itself anyone religiously taking anti-retroviral therapy for more than six months will reach an undetectable viral load.

But in this case, the researchers said they found no trace of dormant HIV-infected cells in his system.These latent cells can become active as soon as treatment stops, making people sick again.

The researchers announced that virus-detecting blood tests did not show any remaining traces of HIV in the mans blood. The man also did not show any signs of having antibodies to the virus.

Prior to this, just two people had been cured of HIV.

First was the Berlin Patient, an American man named Timothy Ray Brown, who received a bone marrow transplant in 2007 in Berlin, Germany.

Brown had leukemia, and required a bone marrow transplant to survive. His doctors sought bone marrow from someone with an HIV-resistant gene. Post-transplant, Brown suffered a series of health issues, he needed to be put in a medically induced coma, and nearly died. But not only was his cancer gone, so was his HIV. He is still alive today, with no HIV, and no need for the anti-retroviral therapy that HIV-positive people must take habitually.

In 2019, the London Patient, a man named Adam Castillejo, became the second person ever to enter long-term remission from HIV. Castillejo, who was treated in London, England, had two bone marrow transplants. His recovery process was less intense, assuaging scientists concerns that Brown had only been cured because of the massive destruction to his immune system, which also rid him of HIV.

Deeks said that independent lab results will be needed to confirm these results. The Brazilian research team has offered to send the mans blood samples to other labs.

When HIV enters the body, it inserts genetic material into the DNA of its hosts immune cells. This forces the cells to make copies of the virus. Some active HIV-infected cells are created, and some latent HIV-infected cells are created. These cells are infected with HIV but are not actively producing new HIV, according to the NIH.

But there is a difference between testing negative for HIV, as some people do after taking medication that makes their HIV undetectable, and having zero traces of HIV in your RNA or DNA. In the first instance the virus is controlled within the body, but in the second instance it is entirely removed from the body.

Many researchers have announced they have cured HIV in their patients, only for the disease to return a short while later.

A baby in Mississippi stopped taking antiretroviral medication at 18 months, researchers eagerly announced that the virus was gone, and then two years later, in 2014, researchers detected HIV in the child again. In 2013, two Boston patients received bone marrow transplants, and headlines declared that they had been cured, only for the virus to resurface again.

The So Paulo Patient has gone 66 weeks without showing signs of the virus.

Fate Therapeutics Announces FDA Clearance of IND Application for First-ever iPSC-derived CAR T-Cell Therapy – GlobeNewswire

By daniellenierenberg

FT819 CAR T-cell Product Candidate Derived from Clonal Master iPSC Line with Novel CD19-specific 1XX CAR Integrated into TRAC Locus

Phase 1 Clinical Study will Evaluate FT819 for Patients with Advanced B-cell Leukemias and Lymphomas

SAN DIEGO, July 09, 2020 (GLOBE NEWSWIRE) -- Fate Therapeutics, Inc. (NASDAQ: FATE), a clinical-stage biopharmaceutical company dedicated to the development of programmed cellular immunotherapies for cancer and immune disorders, announced today that the U.S. Food and Drug Administration (FDA) has cleared the Companys Investigational New Drug (IND) application for FT819, an off-the-shelf allogeneic chimeric antigen receptor (CAR) T-cell therapy targeting CD19+ malignancies. FT819 is the first-ever CAR T-cell therapy derived from a clonal master induced pluripotent stem cell (iPSC) line, and is engineered with several first-of-kind features designed to improve the safety and efficacy of CAR T-cell therapy. The Company plans to initiateclinical investigation of FT819for the treatment of patients with relapsed / refractory B-cell malignancies, including chronic lymphocytic leukemia (CLL), acute lymphoblastic leukemia (ALL), and non-Hodgkin lymphoma (NHL).

The clearance of our IND application for FT819 is a ground-breaking milestone in the field of cell-based cancer immunotherapy. Our unique ability to produce CAR T cells from a clonal master engineered iPSC line creates a pathway for more patients to gain timely access to therapies with curative potential, said Scott Wolchko, President and Chief Executive Officer of Fate Therapeutics. Four years ago, we first set out under our partnership with Memorial Sloan Kettering led by Dr. Michel Sadelain to improve on the revolutionary success of patient-derived CAR T-cell therapy and bring an off-the-shelf paradigm to patients, and we are very excited to advance FT819 into clinical development.

FT819 was designed to specifically address several limitations associated with the current generation of patient- and donor-derived CAR T-cell therapies. Under a collaboration with Memorial Sloan Kettering Cancer Center (MSK) led by Michel Sadelain, M.D., Ph.D., Director, Center for Cell Engineering, and Head, Gene Expression and Gene Transfer Laboratory at MSK, the Company incorporated several first-of-kind features into FT819 including:

The multi-center Phase 1 clinical trial of FT819 is designed to determine the maximum tolerated dose of FT819 and assess its safety and clinical activity in up to 297 adult patients across three types of B-cell malignancies (CLL, ALL, and NHL). Each indication will enroll independently and evaluate three dose-escalating treatment regimens: Regimen A as a single dose of FT819; Regimen B as a single dose of FT819 with IL-2 cytokine support; and Regimen C as three fractionated doses of FT819. For each indication and regimen, dose-expansion cohorts of up to 15 patients may be enrolled to further evaluate the clinical activity of FT819.

At the American Association for Cancer Research (AACR) Virtual 2020 Meeting, the Company presented preclinical data demonstrating FT819 is comprised of CD8 T cells with uniform 1XX CAR expression and complete elimination of endogenous TCR expression. Additionally, data from functional assessments showed FT819 has antigen-specific cytolytic activity in vitro against CD19-expressing leukemia and lymphoma cell lines that is comparable to that of healthy donor-derived CAR T cells, and persists and maintains tumor clearance in the bone marrow in an in vivo disseminated xenograft model of lymphoblastic leukemia.

Fate Therapeutics has an exclusive license for all human therapeutic use to U.S. Patent No. 10,370,452 pursuant to its license agreement with MSK1, which patent covers compositions and uses of effector T cells expressing a CAR, where such T cells are derived from a pluripotent stem cell including an iPSC. In addition to the patent rights licensed from MSK, the Company owns an extensive intellectual property portfolio that broadly covers compositions and methods for the genome editing of iPSCs using CRISPR and other nucleases, including the use of CRISPR to insert a CAR in the TRAC locus for endogenous transcriptional control.

About Fate Therapeutics iPSC Product PlatformThe Companys proprietary induced pluripotent stem cell (iPSC) product platform enables mass production of off-the-shelf, engineered, homogeneous cell products that can be administered with multiple doses to deliver more effective pharmacologic activity, including in combination with cycles of other cancer treatments. Human iPSCs possess the unique dual properties of unlimited self-renewal and differentiation potential into all cell types of the body. The Companys first-of-kind approach involves engineering human iPSCs in a one-time genetic modification event and selecting a single engineered iPSC for maintenance as a clonal master iPSC line. Analogous to master cell lines used to manufacture biopharmaceutical drug products such as monoclonal antibodies, clonal master iPSC lines are a renewable source for manufacturing cell therapy products which are well-defined and uniform in composition, can be mass produced at significant scale in a cost-effective manner, and can be delivered off-the-shelf for patient treatment. As a result, the Companys platform is uniquely capable of overcoming numerous limitations associated with the production of cell therapies using patient- or donor-sourced cells, which is logistically complex and expensive and is subject to batch-to-batch and cell-to-cell variability that can affect clinical safety and efficacy. Fate Therapeutics iPSC product platform is supported by an intellectual property portfolio of over 300 issued patents and 150 pending patent applications.

About Fate Therapeutics, Inc.Fate Therapeutics is a clinical-stage biopharmaceutical company dedicated to the development of first-in-class cellular immunotherapies for cancer and immune disorders.

Business Update

KOL Event for Alzheimers Program

On July 8, 2020, BrainStorm Cell Therapeutics, Inc. (NASDAQ:BCLI) conducted a Key Opinion Leader (KOL) webinar to discuss the companys upcoming Phase 2a clinical trial of NurOwn in patients with Alzheimers Disease (AD). The event included presentations by two of the lead investigators for the upcoming trial, Dr. Philip Scheltens, Professor of Cognitive Neurology and Director of the Alzheimer Centre at VU University Medical Center in Amsterdam, Netherlands, and Dr. Bruno Dubois, Professor of Neurology at the Neurological Institute of the Salptrire University Hospital in Paris, France. The presentation can be found here.

The companys Phase 2a trial (BCT-201-EU) is expected to enroll approximately 40 patients with prodromal to mild AD. It will be taking place at medical centers in France and the Netherlands. To be eligible for the trial, patients must have been diagnosed with prodromal to mild dementia at least six months prior to enrollment. In addition, patients must score between 20-30 on the Mini-Mental State Exam (MMSE) and have a Clinical Dementia Rating (CDR) global score of 0.5-1.0. The MMSE is a series of questions that are designed to assess a patients mental skills, with the maximum score being 30 points and a score of 20-24 suggesting mild dementia. The CDR is a scale used to characterize six domains of cognitive and functional performance with a score of 0.5 suggesting very mild dementia and a score of 1.0 suggesting mild dementia.

The primary objective of the trial is to assess the safety and tolerability of three intrathecal injections of NurOwn in AD patients. Following bone marrow aspiration during a 10-week run-in period, patients will be treated three times with NurOwn, with eight weeks between treatments. Follow-up visits will occur 12 and 26 weeks following the final injection of NurOwn for a total trial length of 52 weeks. The following figure gives an overview of the trial design.

Cerebrospinal fluid (CSF) and serum will be collected prior to treatment and again at Weeks 0, 8, and 16 to assess changes in various neurotropic, neurodegenerative, and inflammatory factors (e.g., VEGF, HGF, NfL, NfH, MCP-1, IL-6), markers associated with amyloid deposition (e.g., a40, a42), and markers of tau protein levels (e.g., p-tau, t-tau). Additional clinical outcome measures will be analyzed through administration of the following tests:

Clinical Dementia Rating ScaledSum of Boxes (CDR-SB)

Free and Cued Selective Reminding Test (FCSRT)

Neuropsychological Test Battery (NTB)

Delis-Kaplan Executive Function System (D-KEFS) subtests

Alzheimers Disease

Alzheimers disease (AD) is the most common form of dementia in older adults. The disease is named after Dr. Alois Alzheimer, who identified the first case in a 50-year-old woman named Auguste Deter in 1902. Dr. Alzheimer followed her case until her death in 1906, at which point he first publicly reported on it (Alzheimer, 1907).

After Ms. Deters death, Dr. Alzheimer examined her brain and found many abnormal clumps (now known as amyloid plaques) and tangled bundles of fibers (now known as neurofibrillary tangles). Over the next five years, 11 similar cases were reported in the medical literature, with some of them already using the term Alzheimers disease (Berchtold et al., 1998).

The most common early symptom of AD is a gradually worsening ability to remember new information. This is due to neurons associated with forming new memories dying off first. As neurons in other parts of the brain die, individuals experience different symptoms, which include:

Memory loss that disrupts daily life

Inability to plan or solve problems

Difficulty completing familiar tasks

Confusion with location and time

Difficulty with visual images and spatial relationships

Problems with words in speaking or writing

Withdrawal from social activities

Changes in mood, including apathy and depression

Each person progresses through AD at a different rate, and little is known about how or why there is such a marked variation, thus predicting how it will affect someone is quite difficult. One thing that is common to everyone diagnosed with AD is that his or her cognitive and functional abilities will gradually decline. As the disease progresses symptoms can include confusion, irritability, aggression, mood swings, and long-term memory loss. In the final advanced stage of the disease, people need help with the basic activities of living (e.g., bathing, dressing, eating, and using the restroom), they lose the ability to communicate, fail to recognize loved ones, and eventually become bed bound and reliant on round-the-clock care (Frstl et al., 1999). The inability to move makes them more prone to infections, including pneumonia, which are often a contributing factor to the death of those with AD.

Competing Theories for the Cause of Alzheimers

The root cause of Alzheimers is still unknown; however, it is likely to involve a number of different factors as opposed to being due to one single cause. These factors are likely a combination of genetic, environmental, and lifestyle. There are a number of hypotheses that exist to explain the cause of the disease, with the two dominant hypotheses focused on amyloid and tau.

Amyloid hypothesis: This hypothesis proposes that extracellular beta-amyloid deposits are the fundamental cause of the disease (Hardy et al., 1991). Beta-amyloid is a fragment of the larger protein amyloid precursor protein (APP), mutations of which are known to cause FAD. Several lines of evidence support the amyloid hypothesis: 1) the location of APP is on chromosome 21, while those with Down Syndrome (trisomy 21) almost all show signs of AD by 40 years of age (Lott et al., 2005); 2) APOE4 is a major genetic risk factor for AD, and while apolipoproteins enhance the breakdown of beta-amyloid, some isoforms are less capable of performing this task than others, leading to more beta-amyloid buildup on the brain (Polvikoski et al., 1995); 3) mice that harbor a mutant form of APP develop amyloid plaques and Alzheimers-like pathology (Games et al., 1995). Lastly, amyloid plaques are readily identifiable by microscopy in the brains of AD patients (Tiraboschi et al., 2004). While the brains of many older individuals develop some plaques, the brains of AD patients show severe pathological changes specifically within the temporal neocortex (Bouras et al., 1994).

Tau hypothesis: Tau is a protein located mainly within the axonal compartment of neurons and is an important element in microtubule stabilization and neurite outgrowth. In AD, a proportion of tau protein becomes abnormally phosphorylated, dissociates from axonal microtubules, and accumulates in paired helical filaments inside the neuron (Goedert et al., 1991). When this occurs, the microtubules disintegrate causing the collapse of the neurons transport system (Igbal et al., 2005). Just as with beta-amyloid plaques, tau tangles are readily observable in the brains of those affected by AD.

In addition to amyloid and tau, inflammation has been an underappreciated and often overlooked mediator in patients with AD (Akiyama et al., 2000). A multitude of inflammatory markers are found in AD patients brains and a number of studies have shown a link between chronic inflammation and an increased risk of developing AD (Walker et al., 2017; Tao et al., 2018). Thus, a treatment such as NurOwn that can decrease inflammatory mediators could prove beneficial in AD patients.

On Track to Repot Topline Data from Phase 3 ALS Trial in 4Q20

On July 2, 2020, BrainStorm announced that all doses have been administered in the pivotal Phase 3 trial ofrecen NurOwn in patients with amyotrophic lateral sclerosis (ALS) and that it remains on track to report topline data in the fourth quarter of 2020.

The ongoing randomized, double blind, placebo controlled, multi-dose Phase 3 clinical trial is testing the ability of NurOwn to alter disease progression as measured by the ALSFRS-R (NCT03280056). Cells were extracted once from each patient prior to treatment, with all administrations of NurOwn derived from the same extraction of cells due to a cryopreservation process the company developed for long-term storage of mesenchymal stem cells (MSC). Just as with the companys prior studies, there was a 3-month run-in period prior to the first treatment with two additional NurOwn treatments occurring two and four months following the first treatment. The company is focusing the trial on faster-progressing ALS patients since those patients demonstrated superior outcomes in the Phase 2 trial of NurOwn.

BrainStorm Joins Russell 2000 and Russell 3000; Granted SME Status by EMA

On June 23, 2020, BrainStorm announced that its shares would be included in the Russell 2000 Index and the Russell 3000 Index. The annual reconstitution of the Russell indexes is done to capture the 4,000 largest U.S. stocks by market capitalization.

On June 15, 2020, BrainStorm announced that the company has been granted Small and Medium-Sized Enterprise (SME) status by the European Medicines Agency (EMA). SME status allows the company to participate in a number of financial incentives including a 90-100% reduction in the EMA fee for scientific advice, clinical study protocol design, endpoints and statistical considerations, quality inspections of facilities, and fee waivers for selective EMA pre- and post-authorization regulatory filings, including Orphan Drug and PRIME designations.

Conclusion

Were excited about the potential for NurOwn in AD and we look forward to the initiation of the Phase 2a trial later in 2020. We have recently made a few changes to our model, including the inclusion of NurOwn in AD and lowering of the discount rate from 20% to 15% for all indications. We model for the company to file for approval of NurOwn in AD in 2026 and to be granted approval in 2027. We currently estimate peak sales of over $2 billion for NurOwn in AD in both the U.S. and E.U. Using a 25% probability of approval leads to an NPV of $113 million. Combined with the NPV for NurOwn in ALS ($700 million) and MS ($41 million) along with the companys current cash position and potential cash from warrants leads to a valuation for the company of a bit less than $900 million. Dividing by the companys current fully diluted share count of 35.7 million leads to a valuation of $25 per share.
