First therapy recommended for full marketing authorization in the EU for eligible patients with confirmed diagnosis of late infantile or early juvenile MLD variants

One-time treatment with Libmeldy has been shown to preserve cognitive and motor function in most patients

Libmeldy is backed by data across 35 patients with follow-up of up to 8 years post-treatment, demonstrating the potential durability of HSC gene therapy

BOSTON, MA, USA and LONDON, UK I October 16, 2020 I Orchard Therapeutics (Nasdaq: ORTX), a global gene therapy leader, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending full, or standard, marketing authorization for Libmeldy (cryopreserved autologous CD34+ cells encoding the arylsulfatase-A, or ARSA, gene), an investigational gene therapy for the treatment of metachromatic leukodystrophy (MLD), characterized by biallelic mutations in the ARSA gene leading to a reduction of the ARSA enzymatic activity in children with i) late infantile or early juvenile forms, without clinical manifestations of the disease, or ii) the early juvenile form, with early clinical manifestations of the disease, who still have the ability to walk independently and before the onset of cognitive decline.

The CHMPs positive opinion will now be reviewed by theEuropean Commission(EC), which has the authority to grant marketing authorization for Libmeldy in theEuropean Union(EU). A final decision by the EC for Libmeldy is anticipated before the end of 2020. If approved, Libmeldy would be the first commercial therapy and first gene therapy for eligible patients with early-onset MLD.

MLD is a very rare, severe genetic condition caused by mutations in the ARSA gene which lead to neurological damage and developmental regression. In its most severe and common forms, young children rapidly lose the ability to walk, talk and interact with the world around them. A majority of these patients pass away in childhood, with palliative care often as their only option.

Todays positive CHMP opinion for marketing authorization of Libmeldy is a remarkable achievement that we share with the MLD community, as it brings us closer to delivering a one-time, potentially transformative therapy for eligible children suffering from this devastating disease, said Bobby Gaspar, M.D., Ph.D., chief executive officer, Orchard Therapeutics. Data from the Libmeldy clinical program have demonstrated the potential for long-term positive effects on cognitive development and maintenance of motor function, translating to individual preservation of motor milestones such as the ability to sit, stand and/or walk without support, as well as attainment of cognitive skills like social interactions and school attendance, at ages at which untreated patients show severe motor and cognitive impairments.

Libmeldy is designed as a one-time gene therapy, developed in partnership with the San Raffaele-Telethon Institute for Gene Therapy (SR-Tiget) in Milan, Italy, in which the patients own hematopoietic stem cells (HSCs) are selected, and functional copies of the ARSA gene are inserted into the genome of the HSCs using a lentiviral vector before these genetically modified cells are infused back into the patient. The ability of the gene-corrected HSCs to migrate across the blood-brain barrier into the brain, engraft, and express the functional enzyme has the potential to persistently correct the underlying genetic condition with a single treatment.

This is an important milestone toward making the availability of HSC gene therapy a reality for more patients, and it also is extremely rewarding for our multi-disciplinary team at SR-Tiget who has worked relentlessly along this 15-year journey to move the seminal proof of principle studies to the first in-human testing of this therapy, said SR-Tiget director Luigi Naldini, M.D, Ph.D. The robust and durable clinical benefits observed in early-onset MLD patients who received HSC gene therapy are compelling, especially when compared to the natural history of the disease. These results also further illustrate our view that the HSC gene therapy approach has the potential to deliver transformative effects in other storage diseases as well, especially when the cells are designed to overexpress the functional enzyme and provide an enhanced supply of it to the affected tissues.

As a parent, watching your child start down a seemingly normal developmental path only to suddenly and rapidly lose some or all of his or her abilities is heart-wrenching, and the agony is even more acute knowing no approved therapies currently exist for MLD, said Georgina Morton, Chair of ArchAngel MLD Trust. Todays decision to advance Libmeldy to the final EC approval stage represents a huge step forward for the parents of these young children and for all of us in the MLD community.

We are extremely appreciative of the EMAs expedited and thorough review of Libmeldys marketing authorization application, considering the severity of MLD coupled with the limited treatment options available today for young patients, said Anne Dupraz, chief regulatory officer, Orchard Therapeutics. The Agencys collaboration on this assessment is a testament to their broader public health commitment to ensure timely evaluation of new medicines for diseases where a pressing unmet need exists.

Data Supporting the Clinical Profile of Libmeldy

The positive CHMP opinion is supported by clinical studies of Libmeldy in both pre- and early- symptomatic, early-onset MLD patients. Early-onset MLD encompasses the disease variants traditionally referred to as late infantile (LI) and early juvenile (EJ).

Clinical efficacy was based on the integrated analysis of results from 29 patients with early-onset MLD who were all treated with Libmeldy prepared as a fresh (non-cryopreserved) formulation:

Clinical safety was evaluated in 35 patients with early-onset MLD:

Co-primary endpointsThe co-primary endpoints of the integrated efficacy analysis were Gross Motor Function Measure (GMFM) total score and ARSA activity, both evaluated at 2 years post-treatment. Results of this analysis indicate that a single-dose intravenous administration of Libmeldy is effective in modifying the disease course of early-onset MLD in most patients.

Pre-symptomatic LI and EJ patients treated with Libmeldy experienced significantly less deterioration in motor function at 2 years and 3 years post-treatment, as measured by GMFM total score, compared to age and disease subtype-matched untreated patients (p0.008). The mean difference between treated pre-symptomatic LI patients and age-matched untreated LI patients was 71.0% at year 2 and 79.8% at year 3. Similarly, the mean difference between treated pre-symptomatic EJ patients and age-matched untreated EJ patients was 52.4% at year 2 and 74.9% at year 3. Although not statistically significant, a clear difference in GMFM total score was also noted between treated early-symptomatic EJ patients and age-matched untreated EJ patients (28.7% at year 2; p=0.350 and 43.9% at year 3; p=0.054).

A statistically significant increase in ARSA activity in peripheral blood mononuclear cells was observed at 2 years post-treatment compared to pre-treatment in both pre-symptomatic patients (20.0-fold increase; p<0.001) and early-symptomatic patients (4.2-fold increase; p=0.004).

At the time of the integrated data analysis, all treated LI patients were alive with a follow-up post-treatment up to 7.5 years and 10 out of 13 treated EJ patients were alive with a follow-up post-treatment of up to 6.5 years. No treatment-related mortality has been reported in patients treated with Libmeldy.

Key secondary endpointsFor EJ patients who were early-symptomatic when treated with Libmeldy, meaningful effects on motor development were demonstrated when these patients were treated before entering the rapidly progressive phase of the disease (IQ85 and Gross Motor Function Classification (GMFC)1). By 4 years post-disease onset, an estimated 62.5% of treated, early-symptomatic EJ MLD patients survived and maintained locomotion and ability to sit without support compared with 26.3% of untreated early-symptomatic EJ MLD patients, representing a delay in disease progression following treatment with Libmeldy.

A secondary efficacy endpoint that measured cognitive and language abilities as quantified by Intelligence Quotient/Development Quotient (IQ/DQ) found:

Clinical safetySafety data indicate that Libmeldy was generally well-tolerated. The most common adverse reaction attributed to treatment with Libmeldy was the occurrence of anti-ARSA antibodies (AAA) reported in 5 out of 35 patients. Antibody titers in all 5 patients were generally low and no negative effects were observed in post-treatment ARSA activity in the peripheral blood or bone marrow cellular subpopulations, nor in the ARSA activity within the cerebrospinal fluid. Treatment with Libmeldy is preceded by other medical interventions, namely bone marrow harvest or peripheral blood mobilization and apheresis, followed by myeloablative conditioning, which carry their own risks. During the clinical studies, the safety profiles of these interventions were consistent with their known safety and tolerability.

About MLD and Investigational Libmeldy

Metachromatic leukodystrophy (MLD) is a rare and life-threatening inherited disease of the bodys metabolic system occurring in approximately one in every 100,000 live births. MLD is caused by a mutation in thearylsulfatase-A(ARSA) gene that results in the accumulation of sulfatides in the brain and other areas of the body, including the liver, gallbladder, kidneys, and/or spleen. Over time, the nervous system is damaged, leading to neurological problems such as motor, behavioral and cognitive regression, severe spasticity and seizures. Patients with MLD gradually lose the ability to move, talk, swallow, eat and see. Currently, there are no approved treatments for MLD. In its late infantile form, mortality at 5 years from onset is estimated at 50% and 44% at 10 years for juvenile patients.1Libmeldy (autologous CD34+ cell enriched population that contains hematopoietic stem and progenitor cells (HSPC) transduced ex vivo using a lentiviral vector encoding the human arylsulfatase-A (ARSA) gene), formerly OTL-200, is being studied for the treatment of MLD in certain patients. Libmeldy was acquired from GSK inApril 2018and originated from a pioneering collaboration between GSK and the Hospital San Raffaele and Fondazione Telethon, acting through their jointSan Raffaele-Telethon Institute for Gene TherapyinMilan, initiated in 2010.

Every 20 minutes someone in the UK is diagnosed with blood cancer and the register of stem cell donors who are needed to save thousands of patients lives does not currently meet the demand. Only 1 in 3 patients will find a donor match within their family and so every year over 2,000 people in the UK are left searching for a matching blood stem cell donor each year.

Blood cancer patients from Black, Asian or minority ethnicity groups face lower survival odds due to the lack ofdonordiversity. These patients have just a 20% chance of finding the best possible stem cell donor match, compared to 69% for northern European backgrounds.

This is due in part to the low numbers of donors registered from those Black, Asian or ethnic minority backgrounds. Donors from minority ethnic backgrounds make up just 13.1% of the UK stem cell register and because Black, Asian or ethnic minority patients tend to have more varied tissue meaning there is an even more specific biological requirement needed of a donor than for a white patient.

The global pandemic has made this situation even worse. Only 2% of stem cell registrations with DKMS came from black people during lockdown, falling by 20% compared to the same time the previous year.

Vaughn Scott is a patient who received a lifesaving donation from a stranger.

Vaughn Scott (34 years old) lives in Bristol and is grateful to the generous stranger who helped save his life. Theyve given him more time with his two children and the chance to marry his now wife last summer in a beautiful ceremony. Vaughn was incredibly fit and active, playing all kinds of sports and serving in the Navy. It was whilst on deployment across the world that he was urgently flown back to the UK and shockingly diagnosed with acute lymphoblastic leukaemia (ALL).

Vaughn said:

Hearing the diagnosis was the biggest blow Ive ever heard. My mind raced straight to my children and partner. When we learnt there was a way I could go into remission, I was excited that there was a way I could get better but very nervous too. With no family members as a match, all my faith was in a complete stranger that may have registered as a potential stem cell donor. Thankfully my match was found, Im now married and enjoying life with my family and Im so grateful. So many people arent as lucky as me. If you can, please register and give other people the second chance at life that I have been given.

About blood cancer

Blood cancer is the third most common cause of cancer death in the UK but there is a lot of fear around stem cell donation of the process itself and of having a depleted supply of stem cells. This isnt the case. After donation, stem cells regenerate within 2 weeks so the donor wont lose anything. Blood stem cell donation is easy to do and similar to blood donation. Around 90% of all donations are made through a method called peripheral blood stem cell (PBSC). In this method, blood is taken from one of the donors arms and a machine extracts the blood stem cells from it. The donors blood is then returned to them through their other arm. This is an outpatient procedure that is usually completed in 4-6 hours. In just 10% of cases, donations are made through bone marrow collection. This is under general anaesthetic so that no pain is experienced.

Black History Month The struggle to find a lifesaving stem cell donor - Keep the Faith

Bone Marrow Stem Cells Comments Off on Black History Month The struggle to find a lifesaving stem cell donor – Keep the Faith | October 16th, 2020

Indias first saviour sibling experiment is a success, say doctors.

A one-year-old sibling has saved her brothers life by donating her bone marrow. Kavya was conceived by her parents through invitro fertilisation to save her brother, Abhijeet Solanki, who was born with Thalassemia.

Thalassemia is a disorder where the haemoglobin count is low in blood and such persons require frequent blood transfusions.

Abhijeet was born in November 2013 but unlike normal babies he did not achieve the growth milestones. The parents learned that Abhijeet had Thalassemia major. Abhijeet required blood transfusions every 25 days and the gap between two transfusions reduced as he grew. By the age of six Abhijeet had undergone 80 transfusions, recalled his father Sahdev Singh Solanki. The only way to save him was through a bone marrow transplant.

The family was willing to donate their bone marrow but the human leukocyte antigen (HLA) of the family, including that of his older sister, did not match.

The Solanki family consulted many doctors. Mr. Solankis research led him to the saviour sibling concept following which he sought out Manish Banker, medical director of Nova IVF Fertility in Ahmedabad.

Dr. Banker said Mr. Solankis research and the science behind it was known but nobody had approached him with such a request before.

Dr. Banker started the assisted reproductive therapy, called pre-implantation genetic testing, for monogenic disorder with HLA matching. The couple underwent three cycles of IVF and 18 embryos were created. Of this only one perfectly matched Abhijeets HLA. The embryo was implanted in Apla Solanki, who delivered a baby girl a year ago.

We had to wait for the baby to grow. She had to weigh 10 kg before we could draw bone marrow, said Deepa Trivedi, programme director of Sankalp Bone Marrow Unit, CIMS Hospital, Ahmedabad.

Pointing out that the best therapeutic option for Thalassemia major patients is bone marrow transplant from an HLA-identical donor, Dr. Banker said, We are extremely thrilled to be part of reproductive history in India to create the first-ever saviour-sibling through ART. We used pre-genetic diagnosis and screening test, an established method for conceiving a child who may donate cord blood or hematopoietic stem cells for transplantation to save a critically ill sibling.

Mr. Solanki said the transplant was done on March 17. Since then Abhijeet has not needed any blood transfusion, indicating that he had been cured of the disorder. His haemoglobin count was 11.3, Dr. Trivedi said.

Gosselies, Belgium, 14 October 2020, 7am CEST BONE THERAPEUTICS(Euronext Brussels and Paris: BOTHE), the cell therapy company addressing unmet medical needs in orthopedics and other diseases, today announces positive 24-month follow-up results for the Phase IIa study with the allogeneic cell therapy product, ALLOB, in patients undergoing lumbar spinal fusion procedures.

The 24-month data show a high percentage of successful lumbar vertebrae fusion of 90%. Patients also continue to experience important clinical improvements in function and pain, from as early as six months after treatment, up to the 24-month follow-up period.

Degenerative spine disorders have a major impact on the quality of life of patients. These impacts include decreases in the stability of the spine and pain in motion,said Dr. Alphonse Lubansu, M.D., Head of the Spinal Clinic, Erasme University Hospital, Universit libre de Bruxelles. The 24 month follow-up data of this Phase IIa clinical trial have demonstrated that patients treated with ALLOB in spinal fusion procedure show a high incidence in fusion, and benefit from a sustained, clinically meaningful improvement in function and pain throughout the 24 months following treatment together with a good safety profile. These results show that ALLOB in combination with the standard spine fusion surgery could be a promising treatment option to address the currently unmet needs of these patients.

This positive data forlumbar spinal fusion complementsthe strong Phase I/IIa results from ALLOB in patients with delayed union fractures,said Miguel Forte, MD, PhD, Chief Executive Officer of Bone Therapeutics. These studies provide promising clinical evidence for the potential ofBone Therapeuticsunique allogeneic cell therapy platform to address high unmet medical needs in orthopaedics and bone related disorders. We will now hold discussions with global regulators and our partners to explore a variety of options for the next stages of clinical development for ALLOB in different orthopedic indications, while pursuing the phase IIb study of ALLOB in difficult tibial fractures.In addition, theclinical results provide further evidence for the expansion of ALLOB and our platform of differentiated MSCs to other indications.

The multi-center, open-label proof-of-concept Phase IIa study was designed to evaluate the safety and efficacy of ALLOB administered, procedure in which an interbody cage with bioceramic granules mixed with ALLOB is implanted into the spine to achieve fusion of the lumbar vertebrae. The main endpoints of the 24-month follow-up analysis included safety and radiological assessments to evaluate vertebrae fusion (continuous bone bridges) and clinical assessments to evaluate improvement in patients functional disability as well as reduction in back and leg pain. The study evaluated 30 patients treated with ALLOB, 29 patients attended the 24-month visit.

Radiological data was collected from CT-scans at 24 months and assessed by three external readers. It showed a successful fusion of the lumbar vertebrae in 27 out of 30 patients (90%). In addition, the remaining 3 patients showed radiological evidence of bone formation. Treatment with ALLOB also resulted in a clear and statistically significant clinical improvement in function and reduction in pain over the 24-month follow-up period. Functional disability improved from the pre-treatment baseline to 24-month by a mean score of 60% (p<0.001) on the Oswestry Disability Index(1). Back and leg pain were strongly reduced by 57 to 62% (p<0.001) and 68 to 70% (p<0.001) respectively compared to pre-treatment baseline. Treatment with ALLOB was generally well-tolerated by the patients, consistent with previous reported results.

(1)The Oswestry Disability Index (ODI) is an index derived from the Oswestry Low Back Pain Questionnaire used by clinicians and researchers to measure a patients permanent functional disability. This validated questionnaire was first published by Jeremy Fairbank et al. in Physiotherapy in 1980. ODI score of 0%-20%: minimal disability; 21%-40%: moderate disability; 41%-60%: severe disability; 61%-80%: crippled; 81%-100%: bed bound.

About Spinal Fusion

Due to ageing populations and sedentary lifestyles, the number of people suffering from degenerative spine disorders continues to increase. Today, spinal fusion procedures are performed to relieve pain and improve patient daily functioning in a broad spectrum of degenerative spine disorders. Spinal fusion consists of bridging two or more vertebrae with the use of a cage and graft material, traditionally autologous bone graft or demineralised bone matrix placed into the intervertebral space for fusing an unstable portion of the spine and immobilizing a painful intervertebral motion segment. Over 1,000,000 spinal fusion procedures are performed annually in the US and EU, of which half at lumbar level and the market is growing at a rate of 5% per year. Although spinal fusion surgery is routine, non-fusion, slow progression to fusion and failure to eliminate pain are still frequent with up to 35% of patients not being satisfied with their surgery.

About ALLOB

ALLOB is the Companys off-the-shelf allogeneic cell therapy platform consisting of human allogeneic bone-forming cells derived from cultured bone marrow mesenchymal stem cells (MSC) from healthy adult donors, offering numerous advantages in product quality, injectable quantity, production, logistics and cost as compared to an autologous approach. To address critical factors for the development and commercialisation of cell therapy products, Bone Therapeutics has established a proprietary, optimised production process that improves consistency, scalability, cost effectiveness and ease of use of ALLOB. This optimized production process significantly increases the production yield, generating 100,000 of doses of ALLOB per bone marrow donation. Additionally, the final ALLOB product will be cryopreserved, enabling easy shipment and the capability to be stored in a frozen form at the hospital level. The process will therefore substantially reduce overall production costs, simplify supply chain logistics, improve patient accessibility and facilitate global commercialisation. The Company will implement the optimized production process for all future clinical trials with ALLOB.

Building on the transformative impetus from the first Food and Drug Administration (FDA)-approved Janus kinase (JAK) 1/2 inhibitor, ruxolitinib (Jakafi), in the clinical landscape of myeloproliferative neoplasms (MPNs), we are entering a new era of multiple JAK inhibitors and other diverse classes of drugs in rapid clinical development. Advancements in elucidating the pathophysiology of MPNs have spurred significant progress in developing novel promising agents or combination regimens with ruxolitinib to treat patients who are unresponsive to standard treatments or have specific clinical needs.

In myelofibrosis (MF), the most aggressive MPN, with an average survival of 5 to 7 years, abnormal clonal hematopoietic stem cell proliferation in the bone marrow (BM) leads to liberation of pro-inflammatory cytokines and extensive fibrosis, causing progressive pancytopenia, especially anemia and thrombocytopenia, along with splenomegaly and other symptoms, compromising quality of life.1

For nearly a decade, ruxolitinib has been the centerpiece therapy for patients with MF, markedly improving splenomegaly and constitutional symptoms and providing survival benefit.2 The second FDA-approved JAK2 inhibitor, fedratinib (Inrebic), may actually be a good second-line option for patients who are ruxolitinib-resistant with intermediate-2 and high-risk MF (primarily thrombocytopenic and characterized by platelet counts 50100 109/L).3 At present, 2 ongoing phase 3 clinical trials, the single-arm FREEDOM trial (NCT03755518) and the double-arm FREEDOM 2 trial (NCT03952039), are assessing the efficacy and safety of fedratinib in patients with MF who are resistant/refractory/intolerant to ruxolitinib. The FREEDOM trials are important because the previous JAKARTA studies (NCT01523171, NCT01437787) were placed on hold or terminated given concerns for the development of Wernicke encephalopathy. Pacritinib is a potent inhibitor of both JAK2 and fms-related receptor tyrosine kinase

3, or FLT3, but does not affect JAK1. Pacritinib is being evaluated in comparison with the physicians choice in an ongoing phase 3 trial (PACIFICA; NCT03165734) in patients with MF and severe thrombocytopenia (baseline platelet count < 50 109/L) at the optimal dose determined in the PAC203 study (200 mg twice daily; NCT03165734).3 Successful clinical development of pacritinib will provide a non-myelosuppressive JAK2 inhibitor for frontline treatment of patients with MF who have severe thrombocytopenia, a setting currently lacking approved drugs. Another JAK1/2 inhibitor that is in advanced clinical development and complements its predecessors is momelotinib, possessing the exclusive attribute to improve anemia, which becomes severe in patients with MF.3 At present, momelotinib is undergoing evaluation in patients who are symptomatic and anemic with advanced MF, previously treated with a JAK inhibitor, in a phase 3 trial (MOMENTUM; NCT04173494); the comparator drug is danazol.

Targeting anemia and thrombocytopenia. Given that patients with MF experience disease-associated and JAK inhibitor-induced anemia, several clinical trials have been evaluating drugs counteracting anemia, as monotherapies or in combination with ruxolitinib, in patients with MF-associated anemia.4 Currently, a global, multicenter phase 2 trial is under way to evaluate the safety and efficacy of luspatercept-aamt (Reblozyl), an activin receptor ligand trap that enhances late-stage erythropoiesis in patients with anemia and MF, including ruxolitinib-treated, transfusion-dependent individuals; a phase 3 trial (INDEPENDENCE) is planned for 2020. Interim results of the phase 2 study demonstrated significant efficacy of luspatercept-aamt, achieving reduction in red blood cell transfusion burden in ruxolitinib-treated patients with MF. Thalidomide (Thalomid), an immunomodulatory agent, significantly improved anemia and thrombocytopenia (platelet counts increased in 60% of patients) in a phase 2 trial evaluating ruxolitinib-treated patients with MF and baseline thrombocytopenia (NCT03069326).5

Synergistic combinations with ruxolitinib targeting epigenetics and JAK2 (TABLE). CPI-0610 is a selective bromodomain and extraterminal protein inhibitor that improved spleen volume, anemia, BM fibrosis, total symptom score, and transfusion dependence (alone or with ruxolitinib) in patients with MF who are enrolled in the global phase 2 MANIFEST study (NCT02158858).3 Furthermore, a phase 1 clinical trial combining an inhibitor of heat shock protein 90 (JAK2 is its chaperone protein), PU-H71, with ruxolitinib in patients with primary/secondary MF is under way (NCT03935555).3 The previous 2 trials are supported by preclinical data showing drug synergism. In a phase 2 trial of ruxolitinib/azacitidine (hypomethylating agent) in patients with MF, synergism was demonstrated in spleen length reduction and BM fibrosis improvement compared with ruxolitinib monotherapy (NCT01787487).5

Synergistic combinations with ruxolitinib targeting antiapoptotic proteins and JAK2. Navitoclax is an orally bioavailable inhibitor of the antiapoptotic B-cell lymphoma 2 (BCL2) family of proteins (primarily BCL extra-large [XL]). In preclinical studies, the nonclinical analogue of navitoclax, ABT-737, in combination with ruxolitinib showed synergism in inducing apoptosis of JAK2 V617F-driven MPN cell lines. Interim data from an ongoing phase 2 clinical trial evaluating navitoclax in combination with ruxolitinib in ruxolitinib-treated patients with MF (with baseline platelet count 100 109/L) showed reduction in spleen volume and BM fibrosis (1 grade) and improvement in total symptom score in a proportion of the patients (NCT03222609).3

Imetelstat is a short oligonucleotide telomerase inhibitor that possibly prolonged median overall survival in patients with MF in the higher-dose (9.4-mg/kg) arm of the phase 2 IMbark study (NCT02426086).3 A phase 3 trial comparing imetelstat to best available therapy in patients with refractory MF is planned for early 2021.

PRM-151, a plasma-derived analogue of the human antifibrotic protein pentraxin 2, improved BM fibrosis in mice models and patients with MF in preclinical and phase 1/2 clinical studies, respectively.3 The promising results merit a phase 3 trial, especially given the scarcity of antifibrotic agents.

The two relatively indolent MPN subtypes, polycythemia vera (PV) and essential thrombocythemia (ET), are characterized by abnorabnormal proliferation of myeloid cells, resulting in elevated blood counts (erythrocytosis and thrombocytosis in PV and ET, respectively), considerable risk of thrombosis and hemorrhage, and progression to secondary MF and acute myeloid leukemia (more common in PV than ET).6 In PV and ET, therapies are aimed at reducing risk of thrombosis, which is higher in patients over 60 years old or with a history of thrombosis, and in ET, when the calreticulin gene, CALR, is absent. A particularly promising agent for the two indolent MPNs is the long-acting ropeginterferon -2b, which was approved in Europe for frontline treatment of high-risk patients with PV and without symptomatic splenomegaly on the basis of the PROUD/CONTINUATION-PV studies [EudraCT, 2012-005259-18 (PROUD-PV) and 2014-001357- 17 (CONTINUATION-PV)].7 The previous investigations demonstrated superiority of ropeginterferon -2b versus hydroxyurea after 3 years of therapy. Besides awaiting possible approval of ropeginterferon -2b to treat patients with PV in the United States, a phase 3 trial of ropeginterferon -2b versus anagrelide in hydroxyurea-resistant/intolerant patients with ET has been planned to start in 2020. Givinostat, an inhibitor of histone deacetylases, demonstrated promising clinical responses (reduction in pruritus and thrombosis, and normalization of hematological parameters) in phase 1/2 studies in patients with JAK2 V617F positive PV and is entering a phase 3 trial in 2021.7 Currently, hydroxyurea and ruxolitinib are the first- and second-line treatments for high-risk patients with PV, respectively, and hydroxyurea is the first-line treatment for ET.

Herein we highlighted an array of drugs ranging from new JAK inhibitors to an antifibrotic agent, epigenetic modifiers, and telomerase and BCL-XL/BCL2 inhibitorsthat are in early or advanced clinical development in MPN. We are looking forward to enrichment of the MPN arsenal with new disease-modifying agents complementing the clinical benefits of ruxolitinib and fulfilling unmet needs in this population.

New Therapies in Development for Myelofibrosis - Targeted Oncology

Bone Marrow Stem Cells Comments Off on New Therapies in Development for Myelofibrosis – Targeted Oncology | October 16th, 2020

Acute Lymphoblastic Leukemia (AML), also called acute myeloblastic leukemia, acute myelogenous leukemia, acute myeloid leukemia, or acute nonlymphocytic leukemia, is an aggressive, fast-growing, heterogenous group of blood cancers that arise as a result of clonal expansion of myeloid hematopoietic precursors in the bone marrow. Not only are circulating leukemia (blast) cells seen in the peripheral blood, but granulocytopenia, anemia, and thrombocytopenia are also common as proliferating leukemia cells interfere with normal hematopoiesis.

Approximately 40-45% of younger and 10-20% of older adults diagnosed with AML are cured with current standard chemotherapy. However, the outlook for patients with relapsed and/or refractory disease is gloomy. Relapse following conventional chemotherapy remains is a major cause of death.

The process of manufacturing chimeric antigen receptor (CAR) T-cell therapies. [1] T-cells (represented by objects labeled as t) are removed from the patients blood. [2] Then in a lab setting the gene that encodes for the specific antigen receptors is incorporated into the T-cells. [3] Thus producing the CAR receptors (labeled as c) on the surface of the cells. [4] The newly modified T-cells are then further harvested and grown in the lab. [5]. After a certain time period, the engineered T-cells are infused back into the patient. This file is licensed by Reyasingh56 under the Creative Commons Attribution-Share Alike 4.0 International license.Today, the only curative treatment option for patients with AML is allogeneic hematopoietic stem cell transplantation or allo-HSCT, which through its graft-vs.-leukemia effects has the ability to eliminate residual leukemia cells. But it is an ption for only a minority. And despite a long history of success, relapse following allo-HSCT is still a major challenge and is associated with poor prognosis.

In recent years, rresearchers learned a lot about the genomic and epigenomic landscapes of AML. This understanding has paved the way for rational drug development as new drugable targets, resulting in treatments including the antibody-drug conjugate (ADC) gemtuzumab ozogamycin (Mylotarg; Pfizer/Wyeth-Ayerst Laboratories).

CAR T-cell TherapiesChimeric antigen receptor (CAR) T-cells therapies, using a patients own genetically modified T-cells to find and kill cancer, are one of the most exciting recent developments in cancer research and treatment.

Traditional CAR T-cell therapies are an autologous, highly personalised, approach in which T-cells are collected from the patient by leukopheresis and engineered in the laboratory to express a receptor directed at a cancer antigen such as CD19. The cells are then infused back into the patient after administration of a lymphodepletion regimen, most commonly a combination of fludarabine and cyclophosphamide. Durable remissions have been observed in pediatric patients with B-ALL and adults with NHL.

CD19-targeted CAR T-cell therapies, have, over the last decade, yielded remarkable clinical success in certain types of B-cell malignancies, and researchers have made substantial efforts aimed at translating this success to myeloid malignancies.

While complete ablation of CD19-expressing B cells, both cancerous and healthy, is clinically tolerated, the primary challenge limiting the use of CAR T-cells in myeloid malignancies is the absence of a dispensable antigen, as myeloid antigens are often co-expressed on normal hematopoietic stem/progenitor cells (HSPCs), depletion of which would lead to intolerable myeloablation.

A different approachBecause autologous CAR T-cell therapies are patient-specific, each treatment can only be used for that one patient. Furthermore, because CAR T-cells are derived from a single disease-specific antibody, they are, by design, only recognized by one specific antigen. As a consequence, only a small subset of patients with any given cancer may be suited for the treatment.

This specificity means that following leukopheresis, a lot of work needs to be done to create this hyper personalised treatment option, resulting in 3 5 weeks of manufacturing time.

The manufacturing process of CAR T-cell therapies, from a single academic center to a large-scale multi-site manufacturing center further creates challenges. Scaling out production means developing processes consistent across many collection, manufacturing, and treatment sites. This complexity results in a the realitively high cost of currently available CAR T-cell therapies.

To solve some of the concerns with currently available CAR T-cell therapies, researchers are investigating the option to develop allogenic, off-the-shelf Universal CAR T-cell (UCARTs) treatments that can be mass manufactured and be used for multiple patients.

Allogeneic CAR T-cell therapy are generally created from T-cells from healthy donors, not patients. Similar to the autologous approach, donor-derived cells are shipped to a manufacturing facility to be genetically engineered to express the antibody or CAR, however, in contrast to autologous CAR T-cells, allogeneic CAR T-cells are also engineered with an additional technology used to limit the potential for a graft versus host reaction when administered to patients different from the donor.

One unique benefit ofn this approach is that because these therapies hey are premade and available for infusion, there is no requirement to leukopheresis or a need to wait for the CAR T-cells to be manufactured. This strategy also will benefit patients who are cytopenic (which is not an uncommon scenario for leukemia patients) and from whom autologous T-cell collection is not possible.

PioneersAmong the pioneers of developing allogeneic CAR-T therapies are companies including Celyad Oncology, Cellectis, Allogene Therapeutics, and researchers at University of California, Los Angeles (UCLA) in colaboration with Kite/Gilead.

Researchers at UCLA were, for example, able to turn pluripotent stem cells into T-cells through structures called artificial thymic organoids. These organoids mimic the thymus, the organ where T-cells are made from blood stem cells in the body.

Celyad OncologyBelgium-based Celyad Oncology is advancing a number of both autologous and allogeneic CAR T-cell therapies, including proprietary, non-gene edited allogeneic CAR T-cell candidates underpinned by the companys shRNA technology platform. The shRNA platform coupled with Celyads all-in-one vector approach provides flexibility, versatility, and efficiency to the design of novel, off-the-shelf CAR T-cell candidates through a single step engineering process.

In July 2020, the company announced the start of Phase I trials with CYAD-211, Celyads first-in-class short hairpin RNA (shRNA)-based allogeneic CAR T candidate and second non-gene edited off-the-shelf program. CYAD-211 targets B-cell maturation antigen (BCMA) for the treatment of relapsed/refractory multiple myeloma and is engineered to co-express a BCMA-targeting chimeric antigen receptor and a single shRNA, which interferes with the expression of the CD3 component of the T-cell receptor (TCR) complex.

During the 2020 American Society of Clinical Oncology (ASCO) Virtual Scientific Program in May 2020, the company presented updates from its allogeneic programs, including additional data from the alloSHRINK study, an open-label, dose-escalation Phase I trial assessing the safety and clinical activity of three consecutive administrations of CYAD-101, an investigational, non-gene edited, allogeneic CAR T-cell candidate engineered to co-express a chimeric antigen receptor based on NKG2D (a receptor expressed on natural killer (NK) cells that binds to eight stress-induced ligands and the novel inhibitory peptide TIM TCR Inhibitory Molecule), for the treatment of metastatic colorectal cancer (mCRC).

The expression of TIM reduces signalling of the TCR complex, which is responsible for graft-versus host disease.every two weeks administered concurrently with FOLFOX (combination of 5-fluorouracil, leucovorin and oxaliplatin) in patients with refractory metastatic colorectal cancer (mCRC).

The safety and clinical activity data from the alloSHRINK trial in patients with mCRC demonstrated CYAD-101s differentiated profile as an allogeneic CAR T-cell candidate. Furthermore, the absence of clinical evidence of graft-versus-host-disease (GvHD) for CYAD-101 confirms the potential of non-gene edited approaches for the development of allogeneic CAR-T candidates.

Interim data from the alloSHRINK trial showed encouraging anti-tumor activity, with two patients achieving a confirmed partial response (cPR) according to RECIST 1.1 criteria, including one patient with a KRAS-mutation, the most common oncogenic alteration found in all human cancers. In addition, nine patients achieved stable disease (SD), with seven patients demonstrating disease stabilization lasting more than or equal to three months of duration.

Based on these results, clinical trials were broadened to include evaluating CYAD-101 following FOLFIRI (combination of 5-fluorouracil, leucovorin and irinotecan) preconditioning chemotherapy in refractory mCRC patients, at the recommended dose of one billion cells per infusion as an expansion cohort of the alloSHRINK trial. Enrollment in the expansion cohort of the trial is expected to begin during the fourth quarter of 2020.

CellectisCellectis is developping a universal CAR T-cell (UCART) platform in an attempy to create off-the-shelf CAR T-cell therapies. The companys pipeline includes UCART123, a CAR T-cell therapy designed to targets CD123+ leukemic cells in acute myeloid leukemia (AML). The investigational agent is being studied in two open-label Phase I trials: AML123 studying the therapys safety and efficacy in an estimated 156 AML patients, and ABC123 studying the therapys safety and activity in an estimated 72 patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN).

UCART22Another investigational agent in clinical trials is UCART22 which is designed to treat both CD22+ B-cell acute lymphoblastic leukemia (B-ALL) and CD22+ B-cell non-Hodgkin lymphoma (NHL). Cellectis reported that UCART22 is included in an open-label, dose-escalating Phase I trial to study its safety and activity in relapsed or refractory CD22+ B-ALL patients.

UCART22 harbors a surface expression of an anti-CD22 CAR (CD22 scFv-41BB-CD3z) and the RQR8 ligand, a safety feature rendering the T-cells sensitive to the antibody rituximab. Further, to reduce the potential for alloreactivity, the cell surface expression of the T-cell receptor is abrogated through the inactivation of the TCR constant (TRAC) gene using Cellectis TALEN gene-editing technology.[1]

Preclinical data supporting the development of UCART22 was presented by Marina Konopleva, M.D., Ph.D. and her vteam during the 2017 annual meeting of the American Society of Hematology (ASH) meeting. [1]

Cellectis is also developing UCARTCS1 which is developed to treat CS1-expressing hematologic malignancies, such as multiple myeloma (MM). UCARTCLL1 is in preclinical development for treating CLL1-expressing hematologic malignancies, such as AML.

Cellectis and Allogene Therapeutics, another biotech company involved in the developmen t of CAR T-cell therapies, are developing ALLO-501, another CAR T-cell therapy which targets CD19 and is being developed for the the treatment of patients with relapsed or refractory NHL. Allogene Therapeutics is also developing ALLO-715, an investigational CAR T-cell therapy targeting the B-cell maturation antigen (BCMA) for treating relapsed or refractory multiple myeloma and ALLO-819, which targets CD135 (also called FLT3), for treating relapsed or refractory AML.

Allogene, in collaboration with both Cellectis, Pfizer (which has a 25% stake in Allogene) and Servier have numerous active open-label, single-arm Phase I trials for an off-the-shelf allogeneic CAR-T therapy UCART19* in patients with relapsed or refractory CD19+ B-ALL. Participating patients receive lymphodepletion with fludarabine and cyclophosphamide with alemtuzumab, followed by UCART19 infusion. Adults patients with R/R B-ALL are eligible.

The PALL aims to evaluate the safety and feasibility of UCART19 to induce molecular remission in pediatric patients with relapsed or refractory CD19-positive B-cell acute lymphoblastic leukemia (B-ALL) in 18 pediatric patients.

The CALM trial is a dose-escalating study evaluating the therapys safety and tolerability in 40 adult patients; and a long-term safety and efficacy follow-up study in 200 patients with advanced lymphoid malignancies.

Allogene reported preliminary proof-of-concept results during the annual meeting of the American Society of Hematology (ASH) in December 2018.

Data from the first 21 patients from both the PALL (n=7) and CALM (n=14) Phase I studies were pooled. The median age of the participating patients was 22 years (range, 0.8-62 years) and the median number of prior therapies was 4 (range, 1-6). Sixty-two percent of the patients (13/21) had a prior allogeneic stem cell transplant.

Of the 17 patients who received treatment with UCART19 and who received lymphodepletion with fludarabine, cyclophosphamide and alemtuzumab, an anti-CD52 monoclonal antibody, 14 patients (82%) achieved CR/CRi, and 59% of them (10/17) achieved MRD-negative remission.

In stark contrast, the four patients who only received UCART19 and fludarabine and cyclophosphamide without alemtuzumab did not see a response and minimal UCART19 expansion.

Based on these results, researchers noted that apparent importance of an anti-CD52 antibody for the efficacy of allogeneic CAR-T therapies. In addition, safety data also looked promising. The trial results did not include grade 3 or 4 neurotoxicity and only 2 cases of grade 1 graft-versus-host disease (10%), 3 cases of grade 3 or 4 cytokine release syndrome which were considered manageable (14%), 5 cases of grade 3 or 4 viral infections (24%), and 6 cases of grade 4 prolonged cytopenia (29%).

Precision BiosciencesPrecision Biosciences is developing PBCAR0191, an off-the-shelf investigational allogeneic CAR T-cell candidate targeting CD19. The drug candidate is being investigated in a Phase I/IIa multicenter, nonrandomized, open-label, parallel assignment, dose-escalation, and dose-expansion study for the treatment of patients with relapsed or refractory (R/R) non-Hodgkin lymphoma (NHL) or R/R B-cell precursor acute lymphoblastic leukemia (B-ALL).

The NHL cohort includes patients with mantle cell lymphoma (MCL), an aggressive subtype of NHL, for which Precision has received both Orphan Drug and Fast Track Designations from the U.S. Food and Drug Administration (FDA).

A clinical trial with PBCAR0191 Precision Biosciences is exploring some novel lymphodepletion strategies in addition to fludarabine and cyclophosphamide. Patients with R/R ALL, R/R CLL, R/R Richter transformation, and R/R NHL are eligible. Patients with MRD+ B-ALL are eligible as well. This trial is enrolling patients.

In late September 2020, Precision BioSciences, a clinical stage biotechnology amd Servier, announced the companies have added two additional hematological cancer targets beyond CD19 and two solid tumor targets to its CAR T-cell development and commercial license agreement.

PBCAR20APBCAR20A is an investigational allogeneic anti-CD20 CAR T-cell therapy being developed by Precision Biosciences for the treartment of patients with relapsed/refractory (R/R) non-Hodgkin lymphoma (NHL) and patients with R/R chronic lymphocytic leukemia (CLL) or R/R small lymphocytic lymphoma (SLL). The NHL cohort will include patients with mantle cell lymphoma (MCL), an aggressive subtype of NHL, for which Precision BioSciences has received orphan drug designation from the United States Food and Drug Administration (FDA).

PBCAR20A is being evaluated in a Phase I/IIa multicenter, nonrandomized, open-label, dose-escalation and dose-expansion clinical trial in adult NHL and CLL/SLL patients. The trial will be conducted at multiple U.S. sites.

PBCAR269APrecision Biosciences is, in collaboration with Springworks Therapeutics, also developing PBCAR269A, an allogeneic BCMA-targeted CAR T-cell therapy candidate being evaluated for the safety and preliminary clinical activity in a Phase I/IIa multicenter, nonrandomized, open-label, parallel assignment, single-dose, dose-escalation, and dose-expansion study of adults with relapsed or refractory multiple myeloma. In this trial, the starting dose of PBCAR269A is 6 x 105 CAR T cells/kg body weight with subsequent cohorts receiving escalating doses to a maximum dose of 6 x 106 CAR T cells/kg body weight.

PBCAR269A is Precision Biosciencess third CAR T-cell candidate to advance to the clinic and is part of a pipeline of cell-phenotype optimized allogeneic CAR T-cell therapies derived from healthy donors and then modified via a simultaneous TCR knock-out and CAR T-cell knock-in step with the =companys proprietary ARCUS genome editing technology.

The FDA recently granted Fast Track Designation to PBCAR269A for the treatment of relapsed or refractory multiple myeloma for which the FDA previously granted Orphan Drug Designation.

TCR2 TherapeuticsTCR2 Therapeutics is developing a proprietary TRuC (TCR Fusion Construct) T-cells designed to harness the natural T cell receptor complex to recognize and kill cancer cells using the full power of T-cell signaling pathways independent of the human leukocyte antigen (HLA).

While succesful in hematological malignancies, CAR T-cells therapies have generally struggled to show efficacy against solid tumors. Researchers at TCR2 Therapeutics believe this is is caused by the fact that CAR T-cell therapies only utilize a single TCR subunit, and, as a result, do not benefit from all of the activation and regulatory elements of the natural TCR complex. By engineering TCR T-cells, which are designed to utilize the complete TCR, they have demonstrated clinical activity in solid tumors. However, this approach has also shown major limitations. TCR T-cells require tumors to express HLA to bind tumor antigens. HLA is often downregulated in cancers, preventing T-cell detection. In addition, each specific TCR-T cell therapy can only be used in patients with one of several specific HLA subtypes, limiting universal applicability of this approach and increasing the time and cost of patient enrollment in clinical trials.

In an attempt to solve this problem, researchers at TCR2 Therapeutics have developped a proprieatarry TRuC-T Cells which are designed to incorporate the best features of CAR-T and TCR-T cell therapies and overcome the limitations. The TRuC platform is a novel T cell therapy platform, which uses the complete TCR complex without the need for HLA matching.

By conjugating the tumor antigen binder to the TCR complex, the TRuC construct recognizes highly expressed surface antigens on tumor cells without the need for HLA and engage the complete TCR machinery to drive the totality of T-cell functions required for potent, modulated and durable tumor killing.

In preclinical studies, TCR2 Therapeutics TRuC T-cells technology has demonstrated superior anti-tumor activity in vivo compared to CAR T-cells therapies, while, at the same time, releasing lower levels of cytokines. These data are encouraging for the treatment of solid tumors where CAR T-cells have not shown significant clinical activity due to very short persistence and for hematologic tumors where a high incidence of severe cytokine release syndrome remains a major concern.

TCR2 Therapeutics product candidates include TC-210 and TC-110.

TC-210 is designed to targets mesothelin-positive solid tumors. While its expression in normal tissues is low, mesothelin is highly expressed in many solid tumors. Mesothelin overexpression has also been correlated with poorer prognosis in certain cancer types and plays a role in tumorigenesis. TC-210 is being developed for the treatment of non-small cell lung cancer, ovarian cancer, malignant pleural/peritoneal mesothelioma and cholangiocarcinoma.

The companys TRuC-T cell targeting CD19-positive B-cell hematological malignancies, TC-110, is being developed to improve upon and address the unmet needs of current CD19-directed CAR T-cell therapies. The clinical development TC-110 focus on the treatment of adult acute lymphoblastic leukemia (ALL), diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL). Preclinical data demonstrates that TC-110 is superior to CD19-CAR-T cells (carrying either 4-1BB or CD28 co-stimulatory domains) both in anti-tumor activity as well as the level of cytokine release which may translate into lower rates of adverse events. The development of TC-110 starts with autologous T-cells collection by leukopheresis. These T-cells undergo genetic engineering to create TRuC-T cells targeting CD19.

This strategy combines the best features of CAR T-cells and the native T-cell receptor. It is open for R/R NHL and R/R B-ALL.

AUTO1Auto1 is an autologous CD19 CAR T-cell investigational therapyis being developped by Autolus Therapeutics. The investigational drug uses a single-chain variable fragment (scFv) called CAT with a lower affinity for CD19 and a faster off-rate compared to the FMC63 scFv used in other approved CD19 CAR T-cell therapies. The investigational therapy is designed to overcome the limitations in safety while maintaining similar levels of efficacy compared to current CD19 CAR T-cell therapies.

Designed to have a fast target binding off-rate to minimize excessive activation of the programmed T-cells, AUTO1 may reduce toxicity and be less prone to T-cell exhaustion, which could enhance persistence and improve the T-cells abilities to engage in serial killing of target cancer cells.

In 2018, Autolus signed a license agreement UCL Business plc (UCLB), the technology-transfer company of UCL, to develop and commercialize AUTO1 for the treatment of B cell malignancies. AUTO1 is currently being evaluated in two Phase I studies, one in pediatric ALL and one in adult ALL.

CARPALL trialInitial results from the ongoing Phase I CARPALL trial of AUTO1 were presented during European Hematology Association 1st European CAR T Cell Meeting held in Paris, France, February 14-16, 2019.

Enrolled patients had a median age of 9 years with a median of 4 lines of prior treatment. Seventeen patients were enrolled, and 14 patients received an infusion of CAR T cells. Ten of 14 patients had relapsed post allogeneic stem cell transplant. Eight patients were treated in second relapse, 5 in > second relapse and 3 had relapsed after prior blinatumomab or inotuzumab therapy. Two patients had ongoing CNS disease at enrollment.

This data confirmed that AUTO1 did not induces severe cytokine release syndrome (CRS) (Grade 3-5). Nine patients experienced Grade 1 CRS, and 4 patients experienced Grade 2 CRS. No patients required tociluzumab or steroids. As previously reported, one patient experienced Grade 4 neurotoxicity; there were no other reports of severe neurotoxicity (Grade 3-5). The mean cumulative exposure to AUTO1 CAR T-cells in the first 28 days as assessed by AUC was 1,721,355 copies/g DNA. Eleven patients experienced cytopenia that was not resolved by day 28 or recurring after day 28: 3 patients Grades 1-3 and 8 patients Grade 4. Two patients developed significant infections, and 1 patient died from sepsis while in molecular complete response (CR).

With a single dose of CAR T cells at 1 million cells/kg dose, 12/14 (86%) achieved molecular CR. Five patients relapsed with CD19 negative disease. Event free survival (EFS) based on morphological relapse was 67% (CI 34-86%) and 46% (CI 16-72%) and overall survival (OS) was 84% (CI 50-96%) and 63% (CI 27-85%) at 6 and 12 months, respectively.

CAR T cell expansion was observed in all responding patients (N=12), with CAR T cells comprising up to 84% of circulating T cells at the point of maximal expansion. The median persistence of CAR T-cells was 215 days.

The median duration of remission in responding patients was 7.3 months with a median follow-up of 14 months. Five of 14 patients (37%) remain in CR with ongoing persistence of CAR T-cells and associated B cell aplasia.

Fate TherapeuticsFT819 is an off-the-shelf CAR T-cell therapy targeting CD19 being developed by Fate Therapeutics. The T-cells are derived from a clonal engineered master induced pluripotent stem cell line (iPSCs) with a novel 1XX CAR targeting CD19 inserted into the T-cell receptor alpha constant (TRAC) locus and edited for elimination of T-cell receptor (TCR) expression.

Patients participating in the companys clinbical trial will receive lymphodepletion with fludarabine and cyclophosphamide. Some patients will also receive IL-2. Patients with R/R ALL, R/R CLL, R/R Richter transformation, and R/R NHL are eligible. Patients with MRD+ B-ALL are eligible as well.

At the Annual Meeting of the American Societ of Hematology held in December 2019, researchers from Fate Therapeutics presented new in vivo preclinical data demonstrating that FT819 exhibits durable tumor control and extended survival. In a stringent xenograft model of disseminated lymphoblastic leukemia, FT819 demonstrated enhanced tumor clearance and control of leukemia as compared to primary CAR19 T-cells. At Day 35 following administration, a bone marrow assessment showed that FT819 persisted and continued to demonstrate tumor clearance, whereas primary CAR T cells, while persisting, were not able to control tumor growth. [2]

CAR-NK CD19Allogeneic cord blood-derived Natural Killer (NK) cells are another off-the-shelf product that does not require the collection of cells from each patient.

Unlike T-cells, NK-cells do not cause GVHD and can be given safely in the allogeneic setting. At MD Anderson Cancer Center, Katy Rezvani, M.D., Ph.D, Professor, Stem Cell Transplantation and Cellular Therapy, and her team broadly focuses their research on the role of natural killer (NK) cells in mediating protection against hematologic malignancies and solid tumors and strategies to enhance killing function against various cancer.

As part of their research, the team has developed a novel cord blood-derived NK-CAR product that expresses a CAR against CD19; ectopically produces IL-15 to support NK-cell proliferation and persistence in vivo; and expresses a suicide gene, inducible caspase 9, to address any potential safety concerns.

In this phase I and II trial researchers administered HLA-mismatched anti-CD19 CAR-NK cells derived from cord blood to 11 patients with relapsed or refractory CD19-positive cancers (non-Hodgkins lymphoma or chronic lymphocytic leukemia [CLL]). NK cells were transduced with a retroviral vector expressing genes that encode anti-CD19 CAR, interleukin-15, and inducible caspase 9 as a safety switch. The cells were expanded ex vivo and administered in a single infusion at one of three doses (1105, 1106, or 1107 CAR-NK cells per kilogram of body weight) after lymphodepleting chemotherapy. The preliminarry resilts of the trials confirmed that administration of CAR-NK cells was not associated with the development of cytokine release syndrome, neurotoxicity, or graft-versus-host disease, and there was no increase in the levels of inflammatory cytokines, including interleukin-6, over baseline.

The study results also demonstrated that of the 11 patients who were treated, 8 patients (73%) had a response. Of these patients, 7 (4 with lymphoma and 3 with CLL) had a complete remission ICR), and 1 had remission of the Richters transformation component but had persistent CLL. Noteworthy was that responses were rapid and seen within 30 days after infusion at all dose levels. The infused CAR-NK cells expanded and persisted at low levels for at least 12 months. The researchers also noted that a majority of the 11 participating patients with relapsed or refractory CD19-positive cancers had a response to treatment with CAR-NK cells without the development of major toxic effects.[3]

About NurOwn

NurOwn (autologous MSC-NTF) cells represent a promising investigational therapeutic approach to targeting disease pathways important in neurodegenerative disorders. MSC-NTF cells are produced from autologous, bone marrow-derived mesenchymal stem cells (MSCs) that have been expanded and differentiated ex vivo. MSCs are converted into MSC-NTF cells by growing them under patented conditions that induce the cells to secrete high levels of neurotrophic factors (NTFs). Autologous MSC-NTF cells can effectively deliver multiple NTFs and immunomodulatory cytokines directly to the site of damage to elicit a desired biological effect and ultimately slow or stabilize disease progression. BrainStorm has fully enrolled a Phase 3 pivotal trial of autologous MSC-NTF cells for the treatment of amyotrophic lateral sclerosis (ALS). BrainStorm also recently received acceptance from the U.S. Food and Drug Administration (FDA) to initiate a Phase 2 open-label multicenter trial in progressive multiple sclerosis (MS) and completed enrollment in August 2020.

BrainStorm Announces Financial Results for the Third Quarter 2020 - Citybizlist

Bone Marrow Stem Cells Comments Off on BrainStorm Announces Financial Results for the Third Quarter 2020 – Citybizlist | October 16th, 2020

I am a clinical immunologist that happens to also be a stem cell scientist with 45 years of experience. The first CD34 bone marrow transplantation in 1978 was done at Roswell Park using FACS flow cytometry. We watch GvHD take hold to many leukemia patients to these brave patients trying to save their life with no way to treat them, until now with MSC (mesenchymal stem cells).

I watched many patients give their lives to science research for a chance of cures, which we had successes 40 years forward, if you get CML, CLL you have 98% of treatment or cure. CAR T and other treatments etc.

My concerns (are that) the media is presenting a perspective in vacuum of the stem cell world in California. Prop 71 put California in play and pushed embryonic research. The people of California need to protect their investment of $3.3 billion, or the industry leadership will be lost along with the clinical trials supported by CIRM. Please do not underestimate the RPE for blindness. #1 unmet medical need when the Japanese pharma Astellas bought Ocata in 2015 and put it on the shelf setting back embryonic research.

Lets look at say, Mesoblast, a Australian stem cell company and the leader in field with four studies. (They) had a setback recently of their BLA of SR aGvHD for kids under 12 years old (which is a death sentence) using MSC stem cells (approved for treatment in Japan for two years now) on the first stem cells for regenerative medicine to be approved the FDA, on Sept. 30, 2020. Mesoblast has 330 double blind studies for Covid19 treatment.

We will know before Christmas if FDA will approve these cells. MSC will be better than vaccinations, with super antigens stimulating the immune memory cells being develop by many companies and Federal government.

Two points: federal funding for embryonic research is not very well supported, and you cannot put a price tag on the patients who are willing to put their life on the line for hope and a chance.

Stay in the game California - do not be shortsighted.

Covid-19 Lockdown Impact: Rheumatoid Arthritis Stem Cell Therapy Market Growth and Demand (YEAR), Projected Fact.MR - The Cloud Tribune

Bone Marrow Stem Cells Comments Off on Covid-19 Lockdown Impact: Rheumatoid Arthritis Stem Cell Therapy Market Growth and Demand (YEAR), Projected Fact.MR – The Cloud Tribune | October 14th, 2020

An appeal has gone out to help an 11-year-old girlwho needs a stem cell transplant from a stranger, to give her a second chance of life.

Arya was diagnosed with a rare blood disorder. But following a diagnosis of aplastic anaemia, a serious condition that occurs when the body stops producing enough new blood cells, she will also be starting immunosuppressant treatment.

This means her immune system isn't working as it should, putting her at a greater risk of infections.

To cure her aplastic anaemia Arya needs a lifesaving stem cell transplant. Blood cancer charity Antony Nolan is searching the worldwide stem cell registers for a donor whose tissue type matches Arya's and who is willing to donate their stem cells to help her live a normal life again.

However, the search for a perfect match is difficult for people like Arya, who is half Indian, with mixed ethnicity so she is sharing her story with Anthony Nolan in order to raise awareness of the need for more people of mixed race to join the stem cell register.

She said, "'They said it would be hard to find a donor for me because of my ethnicity but it isn't impossible. There is hope."

The best possible match for Arya is most likely to have the same background or mix of ethnicities. Currently, people with mixed Asian or other minority backgrounds have a 20% chance of finding a match from an unrelated donor, compared with nearly 70% for people with white, north European heritage.

Arya was diagnosed earlier this year and is receiving treatment at St Mary's Hospital, London.She added, 'When I first became unwell, I remember getting a stomach ache. At first it felt like a stitch but the pain didn't go away so I had more tests.'

These tests revealed something more serious. Arya's mum Brundha recalls: "Arya has always been fit and healthy, but life changed very quickly; all of a sudden we were talking to doctors about aplastic anaemia and Arya has had to stop many of the things she liked doing because her platelets, the tiny blood cells that help your body form clots, were low."

The family were given news of the treatment Arya would need to undergo and the need for a suitable donor.As the search continues, waiting for a match for Arya has inspired the Lloyd family to share their story. Their aim is to raise awareness of the need for more stem cell donors of mixed ethnicities to join the Anthony Nolan register and so increase the likelihood of finding a match for young people like Arya.

Brundha said: 'Because Arya is of mixed race, it was always unlikely we would find a match quickly. We have therefore started this appeal because we don't want to give up hope. It's a waiting game, but there could be someone out there who is a match. We also understand that younger people make better matches, so we would like to do all we can to make this more widely known.'

Aryas Consultant, Professor Josu de la Fuente, who is a Consultant Haematologist and Director of the Paediatric Bone Marrow Transplant Programme at Imperial College Healthcare in London said A well matched donor offers the best opportunity for Arya to establish normal blood production long-term and not to worry about the future.

"I will urge anyone, but particularly those of mixed ethnicity to consider joining the Anthony Nolan register so that no child with blood disorders faces an uncertain future: we can all contribute and be part of the solution.

Arya added: 'What stands out most for me are the bone marrow biopsies and being undergeneral anaesthetic for the first time.'

Rebecca Pritchard leads Anthony Nolan's work to recruit donors aged 1630 to its stem cell register. Rebecca says: 'Despite all she is going through, Arya is standing up to share her story in order to inspire people of mixed background to join the register. There is a potential lifesaver out there who could help her. If you're aged 1630 you can join the Anthony Nolan register online by completing a form and swabbing your cheeks with swabs we'll send in the post.

'Each time we're told a patient is in need of a transplant we'll check whether you're a match for them; if you're found to be a match you could give your stem cells to give hope to families like Arya's.'

Brundha said, 'We were unprepared for this and when it happens you want to know there is a source of donors for your child. That's why we're doing this to highlight the need. Being on the register could have a major impact on someone else's life. It's such an important thing you could do without realising.

"Families would be eternally grateful. You may never be called on, but if you are you could be a lifeline for someone. One person out there could be that person. It's a win-win for everybody.'

Arya added: 'The message I would like people to take away is Never give up hope and please join the register.

Dr. Odalis Mara de la Guardia Pea, an expert immunologist, describes as "encouraging" preliminary findings obtained at the conclusion of the first phase of clinical trials evaluating the use of stem cells in patients facing lung damage caused by COVID-19.

The study, begun during the month of May at the Cuban Institute of Hematology and Immunology (IHI), was undertaken with a view toward eliminating or reducing interstitial inflammatory or fibrotic lung lesions following the infection.

The doctor, also an infectious disease specialist and head of External Services at the IHI, explains that the research will have significant impact "if, as we hope, stem cell therapy produces positive results in these patients with pulmonary alterations post-COVID-19.

"If the treatment is effective, it will be generalized across the entire country, improving the quality of life and respiratory capacity of these patients," she stated with the enthusiasm of someone devoted to the most important mission in the world: saving lives.

THE LUNG, THE "TARGET" ORGAN

De la Guardia Pea commented that, although SARS-COV-2 has a variety of dissimilar effects (cardiovascular, renal, cerebral, vascular, in distal or lower limbs, and others); the "target" organ in the case of COVID-19 is the lung, in which patients experience the most serious impact, both during the disease and once they have recovered, a pattern being studied internationally.

"We have detected cases, specifically in Cuban patients, who have presented this kind of affectation, especially those who have suffered symptoms over a longer period. Among those visited for the study, there were cases of important pulmonary alterations, which is the most frequent, but perhaps not the most serious," the specialist continued.

RECRUITMENT OF VOLUNTEERS

"These recruitment consultations were atypical, as they were done in the field, visiting the homes of recovered patients," the doctor explained, adding that potential volunteers needed to meet several criteria for inclusion in the clinical trials.

Those selected were between 18 and 70 years of age, of both sexes, who had contracted COVID-19 thirty days prior to the trial treatment, testing negative on a PCR at the time of recruitment, and exhibited respiratory symptoms since the beginning of the disease.

Specifically sought for the trials were patients who experienced a more torpid evolution of the disease, those who were hospitalized for more than 20 days, requiring oxygen, assisted ventilation, or the use of some aerosol as treatment, upon reaching serious or critical condition.

"More than 130 homes were visited over almost three months, from May to June; and 141 patients were interviewed, of which about 50 were studied. Twenty patients were included in the trial, which was the determined number," the doctor reported.

PULMONARY SEQUELAE

"During the investigation, several long term effects of COVID-19 were noted, although the most frequent involved the lungs. In some cases, indications of pulmonary fibrosis were detected, a condition that cannot be completely corrected, and can only be treated to increase lung capacity and improve quality of life," the doctor explained.

"The study is still in progress. The first phase has been completed, but there is some time remaining before final evaluation of the patients. What we can say is that, thus far, we are very happy with the results we have observed, they are encouraging," she emphasized.

UNFORGETTABLE STORIES

-Could you recount some stories that particularly impacted you?

-The first day I went out to recruit volunteers, I arrived at the home of a patient who, when she opened the door, exhibited obvious difficulty breathing, evident in plain sight.

We conducted the interview and learned that she experienced this difficulty on a daily basis, five weeks after being diagnosed with COVID-19 and 15 days after a negative PCR test.

This case was significant because we became aware of the lingering effects some patients face, who after having the disease, being discharged and completing all treatment, can have symptoms for a long time.

On another occasion, a patient received us effusively, grateful that he would continue to be treated, that he would receive some follow-up. This attitude was very common in many cases, confirming for us that the patients we visited were still feeling unwell, despite having recovered and been discharged from the hospital.

YOU CAN BE ASYMPTOMATIC OR YOU CAN DIE

"You can be infected and be asymptomatic, or develop the most severe symptoms of the disease and die. This is random, no one understands or can control it," the specialist warns, emphasizing the importance of being fully conscious of taking care of ourselves, since anyone can develop an aggressive case of COVID-19.

"I agree with everything Professor Durn says every day at nine o'clock in the morning, about how measures must be maintained and complied with: the use of facemasks, hand washing, shoe disinfection (with doormats soaked in 0.5% hypochlorite at the entrance to common areas), social distancing, and collective discipline.

"The population must take care; success in containing the pandemic lies in individual responsibility," she concluded.

STEM CELL TREATMENT

-When the patient is included in the study, treatment begins by injecting the granulocyte colony stimulating factor, Ior Leukocim, a product manufactured at Cubas Center for Molecular Immunology, to achieve the mobilization of stem cells from the bone marrow to the bloodstream.

-Subsequently, the patient's blood is extracted and mononuclear cells are separated and concentrated.

-This pool of cells includes hematopoietic and non-hematopoietic stem cells, which have immune-regulatory properties and promote the disappearance of lesions and the reconstitution of lung tissue.

-The cells are infused intravenously.

-The patient is evaluated one month following treatment and again at six months, to determine the clinical efficacy of the stem cell therapy.

Stem Cell Banking Market to witness an impressive growth during the forecast period 2020 2025 - Express Journal

Bone Marrow Stem Cells Comments Off on Stem Cell Banking Market to witness an impressive growth during the forecast period 2020 2025 – Express Journal | October 14th, 2020

The global blood and bone marrow cancer treatment market was valued at $38.8B (approx 32.8B) in 2018 and is reportedly expected to reach $74.9B (approx 63.4B) by 2027, expanding at a CAGR of 7.7% from 2019 to 2027.

Blood cancer begins in the bone marrow which is the integral source of stem cells, which are later differentiated into different types of blood cells in the human body. Researchers have stated that approximately 1.85 million new cases of blood cancer will be diagnosed by 2040 throughout the globe.

These are the top global tech PR agencies you should absolutely check out in 2020

Europe holds a market share of 30.8% owing to the supportive regulatory framework provided by the European Medical Agency for the development and sale of medication for the treatment of blood cancer.

In the recent development, blood and bone marrow cancer treatment developer Priothera Limited, has raised 30M in its Series A round of funding led by Fountain Healthcare Partners with participation from co-lead investor HealthCap and funds managed by Tekla Capital Management, LLC, as well as EarlyBird Venture Capital.

According to the medtech startup, the raised funds will be used to progress the clinical development of mocravimod a modulator of sphingosine 1 phosphate (S1P) receptors, to enhance the curative potential of allogenic hematopoietic stem cell transplantation (HSCT) for treating AML.

Priothera expects to generate further randomised clinical data in high-risk AML patients with these funds.

Dublin-based Priothera was founded in 2020 by Drs. Florent Gros and Dhaval Patel. Joining the founding team include experienced industry executive, Dr. Christoph Bucher, Dr. Simone Seiter, and CFO Brice Suire.

The company claims to be leading the way in developing orally applied sphingosine 1 phosphate (S1P) receptor modulators for haematological malignancies. S1P receptor modulators have been suggested to largely reduce egress of T cell subsets from lymphatic tissues allowing for dual inhibition of graft-versus-host-disease (GvHD) and enhancing graft-versus-leukemia benefits in patients receiving allogenic stem cell transplant.

Allogenic stem cell transplant is the only potentially curative approach for AML patients but has unacceptably high mortality with current treatments, says Florent Gros, co-founder, and CEO of Priothera.

Florent Gros further adds, We are excited about mocravimod which has a unique mechanism of action and clinical proof of concept demonstrating its ability to improve survival outcomes for this devastating disease.

Acute myeloid leukemia (AML) is an aggressive and highly proliferative form of cancer where the bone marrow generates abnormal myeloblasts (a type of white blood cell). According to the company, AML is the most common form of leukemia in adults and can metastasise quickly if left untreated. This can typically lead to death within a few months of diagnosis.

Priothera has acquired rights to a drug called mocravimod from Japans Kyorin Pharmaceutical for the treatment of acute myeloid leukaemia.

According to the company, Mocravimod has already been extensively tested in multiple immunologic indications and has shown a survival benefit in an early clinical study evaluating acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL) patients undergoing hematopoietic stem cell transplantation (HSCT).

Priothera is developing mocravimod in AML with the aim of enhancing the curative potential of Hematopoietic Stem Cell Transplantation (HSCT). The company claims that promising early clinical results have revealed that mocravimod has the potential to rebalance the patients immune system by decoupling Graft-versus-Host Disease (GvHD) from Graft-versus-Leukemia (GvL), preventing the first and preserving the latter.

Following the closing of the financing, people who have joined the Board of Directors include Florent Gros (Priotheras co-founder and CEO), Dr. Dhaval Patel (Priotheras co-founder and CSO at UCB), Dr. Manus Rogan (Fountain Healthcare Partners co-founder and MD), Dr. Marten Steen (partner at HealthCap), Dr. Henry Skinner (senior vice president at Tekla Capital Management, LLC) and Lionel Carnot (partner at EarlyBird Venture Capital).

This Dublin-based startup raises 30M to develop promising therapies for leukemia - Silicon Canals

Bone Marrow Stem Cells Comments Off on This Dublin-based startup raises 30M to develop promising therapies for leukemia – Silicon Canals | October 14th, 2020

To keep you healthy from day to day, your body has its own in-built, germ-fighting network.

This network is also known as the lymphatic system, made up of different vessels and organs in your body, from the lymph nodes to the bone marrow. Lymphoma is the name of the cancer that affects this system.

There are many types of lymphoma but Diffuse Large B-Cell Lymphoma (DLBCL) is the most common aggressive type of non-Hodgkin lymphoma, affecting the B-lymphocytes that produce antibodies which help your body fight infections.

According to the World Health Organizations guidance on classifying tumours, DLBCL accounts for 30 to 40 per cent of newly diagnosed cases of non-Hodgkin lymphoma globally.1

In Singapore, Dr Daryl Tan Chen Lung, who specialises in haematology and practises at Mount Elizabeth Hospitals, estimates that lymphoma is the fifth most common cancer in Singapore.2

Unlike other cancer patients, DLBCL patients hardly have any contributing factors to the development of the condition not even hereditary ones though people with existing HIV infections are more prone to getting DLBCL.

As a result of this, and also because lymphoma is less common than other cancers like breast or lung cancer, regular medical check-ups do not test for its genetic indicators. Instead, patients seek medical help only when they spot early symptoms, says Dr Tan. A growing awareness of lymphoma World Lymphoma Awareness Day takes place on Sept 15 each year and better diagnostics measures have led to much earlier detection of the cancer today, compared to a decade ago.

Dr Tan says that early symptoms of DLBCL include lumps in the neck or groin. Sometimes, other organs like the spleen and bone marrow can be affected. However, some patients show no obvious symptoms beyond abdominal pain, fever and loss of weight. It is thus especially important to seek medical attention should you display any of the common symptoms of lymphoma including swollen lymph nodes in the neck, armpit or groin, a persistent fever, excessive night sweats and unexplained weight loss.

Dr Tan adds that the median age of DLBCL patients in Singapore is 60 to 65, though a very small number of patients in their 20s are diagnosed with a subtype of the cancer known as primary mediastinal B-cell lymphoma.

While DLBCL is an aggressive cancer, the good news is that it is highly treatable in the early stages.

Current therapies for treating first-line DLBCL include chemotherapy, chemo-immunotherapy a combination use of chemotherapy and immunotherapy and stem cell transplant in certain groups of patients. About six in 10 of these patients will respond to their treatment3 and not suffer a relapse within the next five years.

This has a huge impact on younger patients who are then able to resume their daily life and go back to work, for example.

Dr Tan remembers a female patient in her early 20s whose career was just taking off. She was admitted with fever and breathlessness. After performing scans on her, it was discovered that there was fluid surrounding her heart and lungs, and she had a tumour in her chest the size of a rugby ball.

Fortunately, because the cure rate for DLBCL is high, the patients condition has since gone into remission.

A combination of chemo-immunotherapy drugs is commonly recommended as a first-line treatment in DLBCL. Radiation therapy or stem cell transplant can also be included as part of the treatment.

However, about four in 10 patients may not eventually respond to these therapies or suffer from a relapse.3 When this happens, treatment options are limited. Some patients can undergo a stem cell transplant, but about half of them are not eligible.4 This group includes older patients with compromised immune systems.

While affected patients can consider continuing with chemotherapy and chemo-immunotherapy, there are new promising treatment options on the horizon, including targeted therapies such as CAR T-cell therapy. These targeted therapies involve using the patients own immune cells also known as T cells or molecules that bind a chemotherapy agent to an antibody to fight cancerous blood cells.

Beyond that, there are also treatment options known as combination therapy. Previously, patients suffering a relapse have had to rely on existing, first-line treatment, which may or may not be effective in combating the cancer. Combination therapy uses the collective effect of different medications to target different areas of cancerous B-cells and destroy them.

Says Dr Tan: [The medical community is] seeing progress in DLBCL immunotherapy. The current cure rate is about 70 per cent. Hopefully, we can increase the number to 80 per cent or more. But we mustnt rest on our laurels as we hope to focus on the 20 per cent of patients who still dont respond to any treatments.

Lymphoma: Higher rates of survival on the horizon - The Straits Times

Bone Marrow Stem Cells Comments Off on Lymphoma: Higher rates of survival on the horizon – The Straits Times | October 14th, 2020

AUSTIN, Texas, Oct. 13, 2020 /PRNewswire/ --Direct Biologics, LLC, announced today that the FDA has granted expanded access for ExoFlo in the treatment of patients with COVID-19 associated acute respiratory distress syndrome (ARDS).

While Direct Biologics is already enrolling patients in EXIT COVID-19, its national multi-center, Phase II, placebo controlled, randomized clinical trial, the new expanded access protocol will make ExoFlo available to a broader group of patients with severe COVID-19, many of whom would not meet acceptance criteria for EXIT COVID-19, often under conditions of "compassionate use."

Co-Founder and Chief Executive Officer, Mark Adams, states, "The FDA's approval of expanded access for ExoFlo signifies a critical milestone in the development of advanced treatment for COVID-19 associated illnesses including ARDS. We are excited to be able to provide our product to patients with ARDS associated with COVID-19 in critical need of treatment."

"Amid a potential surge in new COVID-19 cases moving into the fall and winter seasons, this approval could not have come at a better time," notes Joe Schmidt, Co-Founder and President. "Our team is working hard to advance our Phase II EXIT COVID-19 trial to offer additional treatment options."

"Approval of our expanded access protocol offers an option for doctors to administer ExoFlo as a treatment to reverse disease progression, extending hope to COVID-19 patients who are not responding favorably to standard of care," states Chief Medical Officer, Vik Sengupta, MD. "We at Direct Biologics are grateful for every opportunity to help these additional patients in need."

Also in attendance was Congressman Michael McCaul who commented, "I am thrilled to hear a local company from Austin, Texas, has been approved for Expanded Access IND by the FDA. Their product, ExoFlo, will help treat COVID-19 patients who are at risk of severe respiratory infection, which often leads to life-threatening circumstances. Direct Biologics, with support of the FDA, will bring high-class treatments and services to Americans who need them the most."

This approval comes on the heels of multiple approvals for single patient Emergency Investigational New Drug (eIND) applications granted in September and October. Emergency INDs are a mechanism by which physicians can obtain rapid approval to administer medication to a single patient through a direct appeal to the FDA.

Direct Biologics Granted Expanded Access by FDA for ExoFlo in the Treatment of COVID-19 - PRNewswire

When thinking about donating bone marrow, most will break out in a cold sweat.

The thought of needles, prodding and poking is enough to put anyone off from becoming a donor but Ndinae Muligwe, Sustainability and Donor Recruitment Coordinator for the South African Bone Marrow Registry (SABMR) explained that it is a less complicated and relatively painless process.

The SABMR was established in 1991 and is a non-profit organisation that conducts searches to find matching bone marrow donors for critically ill children and adults in South Africa who cannot find a match in their own families.

Bone marrow transplants help to treat and even sometimes cure illnesses like leukaemia, Non-Hodgkin lymphoma, bone marrow failure, and some genetic blood and immune-system disorders.

Ndinae explained that the likelihood of a donor finding a match is about one in 100 000. What is more concerning is that there are currently only around 74 000 local donors on the South African Bone Marrow Registry.

Although they do form part of the World Marrow Donor Association that represents about 38 million donors, there are not enough donors for the South African demographic.

Ethnicity plays a role when it comes to who is able to donate, and at the moment the numbers do not match the ethnic groups represented in South Africa. You are more likely to find a match within your own ethnic group.

But how do you become a donor and what is the process involved?

Ndinae said it is as easy as registering on the website. Of course there are some questionnaires to fill in and you will have to meet the criteria and be healthy.

The donating age has recently been lowered from 18 to 16 years of age, and applicants must be between 16 and 45 to register as a potential donor.

If you are eligible you will then be contacted by the SABMR to do a cheek swab free of charge.

Peripheral blood stem cell (PBSC) collection is the most likely way of collecting stem cells. These cells are found in your bone marrow and also the blood stream. A five-day course of growth factor or Granulocyte-Colony Stimulating Factors is given prior to the donation to encourage the stem cells to move from your marrow to your blood.

At the time of donation a needle is placed in one arm. The blood is then passed through a machine that collects the stem cells, and the remaining blood is returned to your body similar to donating blood platelets.

You do not have to pay for anything to make a tissue or blood donation of your bone marrow stem cells, the SABMR covers the cost of testing and collection.

Becoming a donor easier than you think - Randfontein Herald

Bone Marrow Stem Cells Comments Off on Becoming a donor easier than you think – Randfontein Herald | October 10th, 2020

A Yes vote authorizes the state to sell $5.5 billion in general obligation bonds primarily for stem cell research and the development of new medical treatments in California. A No vote would mean the state's stem cell research agency will probably shut down by 2023.

In the ramp-up to the 2004 election, a California TV viewer may have come across the popular actor Michael J. Fox urging her to vote Yes on a state proposition. His voice slurred faintly by Parkinsons disease, he still sounded wry, boyish and familiar.

My most important role lately is as an advocate for patients and for finding new cures for diseases, said Fox, eyes level with the camera. Californias Stem Cell Research Initiative 71 will support research to find cures for diseases that affect millions of people, including cancer, diabetes, Alzheimer's and Parkinson's.

Within that 30-second spot, Fox, diagnosed at age 29 with a neurodegenerative disorder that typically does not strike until after 60, used the word "cures" three times.

Proposition 71, which passed with 59% of the vote, authorized the sale of $3 billion in bonds to create an agency that funded stem cell research. The successful campaign grew out of a time, in the early 2000s, when the promise of stem cell and regenerative medicine excited both scientists and the public.

Whether the project has lived up to that promise is a matter of opinion. How voters view the record of the agency may go a long way in their decision whether or not to replenish the fund, which is fast running out of money, with an additional $5.5 billion to be raised with new bonds authorized by Proposition 14, now on the ballot.

President Bush A Demon to Attack

Scientists since the1800s have known about stem cells, which are not yet dedicated to any particular anatomical function and have the potential to become nerve cells, blood cells, skin cells or any other type. They are found in blastocysts, which are human embryos four to five days after fertilization, and in a few areas, such as bone marrow and gonads, in adults.

In the late 1990s, researchers developed ways to steer the development of these cells, and the possibilities for improving medicine seemed endless. If malfunctioning cells were at the root of a particular disease, could new healthy cells tailored to the job fix what was wrong? Scientists and many members of the public were eager to find out.

Anti-abortion groups, however, a key constituency of President George W. Bush, opposed the research, and in 2001 he limited federal funding to a few existing lines of embryonic stem cells, severely curtailing research.

Some in the state of California wanted to get around Bushs restrictions, and Proposition 71 was born.

"(T)hey had this demon they could attack in the campaign the Bush administration," said David Jensen, author of "California's Great Stem Cell Experiment," who also writes the blog California Stem Cell Report. "They could say, 'This is a great opportunity, and the only way we're going to get it done is to do it here in California.'"

The measure created the California Institute for Regenerative Medicine. The stem cell research agency is unique in the U.S.

"No other state has done this kind of level of funding and focus on this kind of thing, said Jensen. It's a really cutting-edge area of science."

A Few Successes

The pace of innovation has been slower than many hoped. As it turned out, grand discoveries were not around the corner, and to date there is no widespread stem cell treatment approved for the public. To date, CIRM has funded more than 64 trials directly and aided in 31 more. Not all have or will result in treatments.

But despite the lack of a marquee cure like one for Alzheimers or Parkinsons, the agency has seen some notable triumphs.

"Probably one of the most spectacular successes they have certainly so far," said Jensen, "is clinical trials that have saved the lives of what they say are 40 children."

Those children were born with severe combined immunodeficiency (SCID), commonly known as "bubble baby syndrome," a rare, generally fatal condition in which a child is born without a working immune system. An FDA-approved gene therapy that grew out of CIRM-funded research can now cure the disease by taking a patients own blood stem cells and modifying them to correct the SCID mutation. The altered cells generate new, healthy blood cells and repair the immune system.

The FDA has also approved two drugs for rare blood cancers that were developed with CIRM funds.

Sandra Dillon, a graphic designer in San Diego, credits one of the drugs with saving her life. She was diagnosed when she was just 28, in 2006. Her doctors told her they would try to manage her symptoms, but that she was going to get progressively sicker.

"Even just the idea of a cure or getting better wasn't even on the table back then," said Dillon, who is featured in ads for the Yes on 14 campaign.

"I remember just praying and begging into the universe, please, someone just look at my disease, please someone help, who is going to look at this thing.

By 2010, Dillon was extremely ill. She connected with a doctor at UC San Diego who received early-stage funding from CIRM and told her she could take part in clinical trials.

"For the first time, there was this moment of, 'Oh, my gosh! There are researchers doing something. And it could help me and I can get access to it.' It was amazing."

The drug received FDA approval in 2019, and today Dillons cancer has retreated to the point where she can live a normal life.

"I love that I am not tethered to a hospital anymore. I can go out on long backpacking trips and hiking and surfing," she said. "I am a completely different person with this drug. And I have a whole future ahead of me."

The original funding raised by Proposition 71 is running out. Proposition 14 would authorize the sale of a new bond to refill the agency piggy bank. Gov. Gavin Newsom, the UC Board of Regents, and scores of patient advocacy groups also support the measure.

Many newspaper editorial boards, however, oppose the proposition, including the San Francisco Chronicle, Mercury News and Los Angeles Times.

Right now the state still owes about $1 billion toward the debt created by Proposition 71. If Proposition 14 passes, the yearly price tag to pay off the new bond would be about $260 million per year for about 30 years.

One of the selling points of the original proposition was the potential for the state to earn big money in royalties from the treatments it helped develop, says Jeff Sheehy, an HIV patient advocate and the only CIRM board member to oppose Proposition 14.

"The promises were made that this would pay for itself. We would be able to pay back the bonds with the money we would get from royalties, etc., etc.

That has not worked out as envisioned: CIRM estimates it has received less than $500,000 in royalties. Early this year, Forty Seven, a company whose therapies were heavily funded by CIRM, sold to Gilead for $4.9 billion. While millions went to various researchers, neither CIRM nor the state of California received anything.

One of the flaws in the original measure is that we [the agency] cannot hold stock in the products that we develop," says Sheehy. "And that's because the California Constitution says that the state of California cannot, as a government entity, hold equity.

Proposition 14 makes it impossible for the state to use profits from its investment on, say, schools or other funding priorities. Instead, any royalties earned must be fed back into programs to make CIRM-funded treatments more affordable.

"What it does is it basically takes all of our returns that we get from this and gives it back to the pharmaceutical and biotech companies," said Sheehy. "It becomes just a blatant giveaway to these companies when we should be requiring access and requiring fair pricing."

Sheehy says he supports medical research, but doesn't like the state going into more debt to pay for it. The greater the state's obligations in bond money, which has to be paid back with interest, the less there is in the general fund, and Sheehy says the state has more pressing needs than stem cell research things like housing, education and transportation.

"The biggest and perhaps the most compelling reason why I feel so strongly that this is not a good idea is that we simply cannot afford it, he said. "If we think this is so important," asks Sheehy, "why don't we just don't pay for [this research] out of the general fund? It would be cheaper.

Opponents of Proposition 14 also point to longstanding complaints of conflicts of interest among the agency board. Most of the $3 billion distributed by the agency has gone to institutions with connections to board members. Critics say the structural conflicts of interest between the board and agency are not addressed in the new measure. Proposition 14 would balloon an already huge board of 29 members to 35.

Funding needs for stem cell research also are not as acute as they were back in 2004. The federal National Institutes of Health now funds some basic stem cell research, spending about $2 billion a year, with $321 million of that going toward human embryonic stem cell research. And private ventures, like nonprofits started by tech billionaires, are pouring more money into biotech.

The problem with assuming that, says Melissa King, executive director of Americans for Cures, the stem cell advocacy group behind the Yes on 14 campaign, is that CIRM fills a neglected funding need.

The NIH does not fund clinical trials at nearly the rate that CIRM can and has been, King said.

She says that's important because of what she calls the "Valley of Death," where promising early-stage research frequently fails to translate into promising treatments that can be tested in clinical-stage research. (What works well in a test tube often does not work well in an organism.) This weeding-out process is costly but necessary. And its where CIRM focused a lot of its effort.

The first- and maybe even second-phase clinical trials, its very difficult to get those funded, King said. It is too much of a risk for business to take on on its own. Venture [capital] isnt going there. Angel [funding] isnt going there.

What voters have to ask themselves, says writer Jensen, is whether stem cell funding is "a high priority for the state of California? Different people make different judgments about that."

CIRM supporters say if Prop. 14 doesn't pass, critical research will stall. Others say federal and private funding will step in and fill the gap.

Absent new funding, the institute expects it will wind down operations leading to a complete sundown in 2023.

NEW YORK, NY, USA and PARIS, France I October 08, 2020 I Cytovia Therapeutics ("Cytovia"), an emerging biopharmaceutical company, announces today that it has entered a research and licensing agreement with Inserm to develop NK engager bi-specific antibodies and iPSC CAR NK cell therapy targeting CD38, a key marker of multiple myeloma. The licensing agreement has been negotiated and signed by Inserm Transfert, the private subsidiary of Inserm, on behalf of Inserm (the French National Institute of Health and Medical Research) and its academic partners. Cytovia is licensing Inserm's CD38 antibody and Chimeric Antigen Receptor (CAR) patent and applying its proprietary NK engager bispecific antibody and iPSC CAR NK technology platforms. The research agreement will include evaluation of the therapeutic candidates at Hpital Saint-Louis Research Institute (Inserm Unit 976) under the leadership of Professors Armand Bensussan and Jean-Christophe Bories.

Dr Daniel Teper, Cytovia's Chairman and CEO commented: "We are delighted to partner with one of the top centers of excellence in the world for research and treatment in hematology. CD38 is a validated target and Natural Killer cells have significant cytotoxicity to Myeloma cells. We are looking forward to bringing promising new options to address the unmet needs of patients with Multiple Myeloma and aim for a cure."

Professor Armand Bensussan, Director of The Immuno-Oncology Research Institute at Hpital Saint-Louis added: "We have demonstrated the selectivity of our novel CD38 antibody in killing myeloma cells but not normal cells such as NK, T, and B cells. The activation of NK cells through NKp46 may enhance the efficacy of the bispecific antibody in patients not responsive to CD38 monoclonal antibody therapy. CD38 CAR NK is a promising approach forrelapsed/refractory patients and an alternative to CAR T therapies."

About Multiple MyelomaMultiple Myeloma is a currently incurable cancer, affecting a type of white blood cell known as plasma cells. It leads to an accumulation of tumor cells in the bone marrow, rapidly outnumbering healthy blood cells. Instead of producing beneficial antibodies, cancerous cells release abnormal proteins causing several complications. While symptoms are not always present, the majority of patients are diagnosed due to symptoms such as bone pain or fracture, low red blood cell counts, fatigue, high calcium levels, kidney problems, and infections. According to the World Cancer Research Fund, Multiple Myeloma is the second most common blood cancer, with nearly 160,000 new annual cases worldwide, including close to 50,000 in Europe. 32,000 in the US, and 30,000 in Eastern Asia. Over 95% of cases are diagnosed late, with a 5-year survival rate of 51%. Initial treatment comprises of a combination of different therapies, including biological and targeted therapies, corticosteroids, and chemotherapy, with the option for bone marrow transplants for eligible patients. Immunotherapy and cell therapy are the most promising new treatment option for Multiple Myeloma, with the potential for long term cancer remission.

About CAR NK cellsChimeric Antigen Receptors (CAR) are fusion proteins that combine an extracellular antigen recognition domain with an intracellular co-stimulatory signaling domain. Natural Killer (NK) cells are modified genetically to allow insertion of a CAR. CAR-NK cell therapy has demonstrated initial clinical relevance without the limitations of CAR-T, such as Cytokine Release Syndrome, neurotoxicity or Graft vs Host Disease (GVHD). Induced Pluripotent Stem Cells (iPSC) - derived CAR-NKs are naturally allogeneic, available off-the-shelf and may be able to be administered on an outpatient basis. Recent innovative developments with the iPSC, an innovative technology, allow large quantities of homogeneous genetically modified CAR NK cells to be produced from a master cell bank, and thus hold promise to expand access to cell therapy for many patients.

There are only a few specialised childhood cancer centres in Southern Africa.

Leukaemia and lymphoma are two of the most prevalent cancers in children in South Africa with between 800 and 1000 children diagnosed annually. Tragically, it is estimated that half of the children with cancer in this country are never diagnosed.

Dr Marion Morkel, Chief Medical Officer at Sanlam, believes that we all need to educate ourselves so we can recognise the symptoms of cancer.

Below, Dr Morkel explains what can be done in the fight against leukaemia and lymphoma.

Knowledge is key

You must be aware of the symptoms related to leukaemia and lymphoma so that you can notify your health professional should you see these symptoms in your child.

Leukaemia

Leukaemia is the most common childhood cancer accounting for 25% of all cases in South Africa.

Symptoms include:

Lymphoma

Lymphoma primarily originates from the lymph nodes and can often appear like any other illness that triggers an inflammatory response.

Symptoms to look out for include:

While other childhood illnesses can present in the same manner as leukaemia and lymphoma, health professionals have been trained to look out for symptoms that persist after routine treatment and will conduct tests to rule out the possibility of these childhood blood-related cancers.

Parents are encouraged to consult their doctor if there are any concerns about their childs health.

Register to become a blood stem cell (bone marrow) donor

The Sunflower Fund is a non-profit organisation that fights blood diseases through a blood stem cell transplant which replaces a persons defective stem cells with healthy ones and can be a potentially life-saving treatment for more than 70 different diseases.

Kim Webster, Head of Communications at The Sunflower Fund advises that finding a matching donor for a stem cell transplant is not as easy as finding a blood type match.

There is only a 1:100 000 chance of a patient finding their life-saving match with siblings only having a 25% chance of a match.

You can register to become a donor online via http://www.sunflowerfund.org.
