Early findings from the phase 1/2a TEM-GBM study presented at the 2022 AACR Annual Meeting displayed potential of temferon to affect the tumor microenvironment of glioblastoma.

Immune system activation and tumor microenvironment alteration were effects observed in patients with glioblastoma treatment with temferon, a genetically modified Tie2-expressing monocyte (TEM) targeting interferon-2 (IFN2), according to early findings of the phase 1/2a TEM-GBM study (NCT03866109) presented in a poster at the American Association for Cancer Research (AACR) 2022 Annual Meeting.

These results provide the initial evidence for on-target activity of Temferon in GBM, said Bernard Gentner, MD, study coauthor and the leader of the translational stem cell and leukemia research unit at San Raffaele Telethon Institute for Gene Therapy in Milan, Italy.

Temferon is an investigational advanced therapy consisting of autologous CD34+-enriched hematopoietic stem and progenitor cells exposed to transduction with a lentiviral vector, driving myeloid-specific IFN2 expression. Genetically modified TEMs target IFN2 expression in the GBM tumor microenvironment.

In order to guarantee stable delivery of genetically engineered TEMs into the tumor, we transduce hematopoietic stem and progenitor cells with a lentiviral vector carrying the IFNa2 transgene transcriptionally regulated by the Tie2 promoter and by post transcriptional elements that guarantee that the transgene is expressed only in myeloid cells that are recruited into the tumor, Gentner said.

TEM-GBM is an open-label, dose-escalation study evaluating the safety and efficacy of Temferon in up to 21 newly diagnosed patients with GBM harboring an unmethylated MGMT promoter. Following surgical resection, up to 15 patients were assigned to 1 of 3 escalating doses of Temferon and 1 of 2 different conditioning regimens in part A of the trial. In Part B, 6 more patients will receive a single dose of Temferon at the recommended phase 2 dose.

Following completion of radiotherapy, patients received a conditioning regimen consisting of carmustine (BCNU) and thiotepa (Tepadina) in cohorts 1 to 4 or busulfan (Busulfex) and thiotepa in cohort 5 prior to administration of Temferon.

In-patient monitoring occurs until hematological recovery, then patients will undergo regular follow-up for up to 720 days. At that point, patients are invited to participate in a long term follow-up study for an additional 6 years.

Eligible adults aged 18 to 70 years must have an ECOG performance score of 0 to 1, a Karnofsky performance score greater than 70%, and adequate cardiac, renal, hepatic, and pulmonary function. Patients with active autoimmune disease or who have received any oral or parenteral chemotherapy or immunotherapy within 2 years of screening are excluded.

The primary end points of the study are Temferon engraftment over the first 90 days, proportion of patients achieving hematologic recovery 30 days after autologous stem cell transplantation, and short-term tolerability of Temferon as defined by stable blood counts, absence of cytopenias, absence of significant organ toxicities greater than grade 2, and absence of Replication Competent Lentivirus.

By the October 15, 2021, data cutoff, the median follow-up was 267 days (range: 60-749). Patients in cohorts 1 to 3 received a dose 0.5-2.0 x 106/kg Temferon with an average vector copy number of 0.70 and a transduction efficiency of 54%. Those in cohorts 4 and 5 received 2.0 x 106/kg Temferon with an average vector copy number of 0.77 and a transduction efficiency of 49%.

Investigators observed increasing proportions of Temferon-derived differentiated cells, as determined by the presence of vector genomes in the DNA of peripheral blood and bone marrow cells, reaching up to 30% at 1 month in the highest treatment cohort (2.0 x 106/kg). Those differentiated cells persisted at lower levels for up to 18 months.

All patients showed in vivo Temferon engraftment, Gentner said. Engraftment was highest at 1 month, and in many patients resembled pretty much the input fraction. Engraftment then decreased, stabilizing at 3 to 6 months around 10%.

Despite the significant proportion of engineered cells, only very low-medium concentrations of interferon alpha were detected in the plasma and in the cerebral spinal fluid, indicating a tight regulation of the vector expression.

Gentner added that Temferon did not delay hemopoietic recovery, and neutrophil and platelet engraftment were similar to standard autologous stem cell procedure.

Investigators did not detect any dose limiting toxicities. Gentner said that, so far, adverse events have been related to progression or the transplant procedure, not to the IFN2 itself.

Drug pricing watchdog ICER, the Institute for Clinical and Economic Review, issued a draft report on bluebird bios gene therapy betibeglogene autotemcel for beta-thalassemia. Despite the proposed price tag of $2.1 million, ICERs not-yet-finalized report supports the therapys cost-effectiveness. This is good news for the recently beleaguered company.

Gene therapies are typically designed to cure a disease by replacing or fixing a damaged gene. Bluebirds therapy, which is listed under the brand name Zynteglo, had been approved in Europe and the UK, where its price is around $1.7 million (U.S.). However, the company pulled the therapy off the market in Europe over what it called a hostile pricing and reimbursement environment.

On April 5, bluebird bio announced it was beginning a comprehensive restructuring in hopes of cutting $160 million in costs over the next two years. It planned to re-focus on near-term catalysts, which include Zynteglo in the U.S., gene therapy for cerebral adrenoleukodystrophy (eli-cel) and a potential biologics license application (BLA) for lovotibeglogene autotemcel (lovo-cel) gene therapy for sickle cell disease. The BLA application is planned for 2023, while the U.S. regulatory decisions are expected this year. The PDUFA date for Zynteglo is Aug.19, 2022, and Sept. 16, 2022, for eli-cel.

As part of the restructuring, the company is cutting its workforce by about 30%.

ICER recommendations arent binding, but they have influence. If ICER says a drug is overpriced, it provides ammunition for payers, such as Medicare and insurers, to push back against proposed prices.

Gene therapies are very expensive. For example,Novartis Zolgensma, the one-time gene therapy onasemnogene abeparvovec for spinal muscular atrophy (SMA), is generally viewed as the most expensive drug with a price tag of $2.1 million. On the other hand, as an apparent cure for a disease that kills children by the age of two, it is very rare. The argument for these therapies, aside from their curative potential for otherwise incurable diseases, is that over the life of the patient, they are cost-effective.

Novartis and Spark Therapeuticss gene therapy Luxturna (voretigene neparvovec) runs about $850,000 per patient in the U.S. The therapy is for inherited retinal dystrophy with RPE65 mutations. It is typically diagnosed in childhood and eventually causes almost total blindness, and the therapy is essentially a cure.

Beta thalassemia is a genetic disease that impairs the ability of red blood cells to manufacture hemoglobin, the molecule in the body that carries oxygen. There are about 40,000 newly diagnosed cases in children each year around the world. People with the most severe form of it develop life-threatening anemia around four to six months of age and have to receive monthly blood transfusions and other treatments, such as iron-chelating drugs. The only other potential cure is hematopoietic stem cell transplantation (HSCT) but requires a donor with a matching human leukocyte antigen (HLA) profile within the appropriate age range.

Bluebirds Zynteglo appears to be another option for a cure, although how long the therapys effects last is something of an open question. The ICER report noted the uncertainties, but concluded that the evidence suggests that beti-cel provides net health benefits to patients with TDT.

The ICER report indicated, per Managed Healthcare Executive, that "patients could be treated without reaching the potential budget impact threshold at three prices (about $1.85 million, $2.11 million and $2.38 million per course of treatment). This analysis was done at several prices to document the percentage of patients who could be treated without crossing a potential budget impact threshold that is aligned with the overall growth in the U.S. economy.

In Phase III trials, 89% of patients who received the therapy became transfusion independent, and in Phase I/II and III trials, those patients remained transfusion-free for at least 42 months. In general, side effects were mild and no deaths were reported. In December 2021, bluebird presented data at the American Society of Hematology meeting from a long-term study (LTF-303) that showed adult and pediatric patients with beta-thalassemia who required regular red blood cell transfusions can produce normal or near-normal levels of total hemoglobin and remain transfusion-free with stable iron markers up to seven years after receiving beti-cel.

A 2017 study published in Blood found that on average, beta-thalassemia patients required 17 transfusions per year, 23 days apart. Mean total healthcare costs for the patients were $128,062, plus or minus $62,260 per year. Total costs were primarily driven by chelation and transfusion costs.

Although the severity of the disease varies, a 2009 study found that people with beta-thalassemia major often die from cardiac complications of iron overload by 30 years of age," making bluebird's new therapy, if it is successful, vital for these patients.

Drug Price Watchdog Calls Bluebird Bio's $2.1 Million Gene Therapy Cost-Effective - BioSpace

The addition of the innate cell engager AMF13 to preactivated and expanded natural killer (NK) cells may represent an effective treatment for pretreated patients with advanced lymphoma, according to findings from a phase 1/2 study (NCT04074746) that were presented during the 2022 AACR Annual Meeting. 1

Results showed that patients experienced a median overall response rate (ORR) of 89.5% (n = 17/19). Overall, 10 patients experienced complete responses (CRs) and 7 experienced partial responses (PRs).2

Lead author Yago Nieto, MD, PhD, a professor of medicine in the Department of Stem Cell Transplantation and Cellular Therapy at the University of Texas MD Anderson Cancer Center, in Houston, discussed the findings during a press conference during the meeting. He said the study team was pleasantly surprised by the quality of tumor responses in patients with resistant lymphomas.

This is the first clinical trial using off the shelf cord blood-derived cytokine-induced memory-likeex vivoexpanded NK cells precomplexed with the innate cell engager AMF13 construct to treat patients with CD30-positive relapsed/refractory Hodgkin lymphoma, he said. We saw very encouraging activity in this population of very heavily pretreated patients.

The current standard of care for relapsed CD30-positive lymphomas is brentuximab vedotin (Adcetris), an antibody-drug conjugate that delivers a toxic cytoskeleton destabilizing agent to cells expressing CD30. However, not all these lymphomas respond to brentuximab vedotin. When that treatment fails, those tumors then become extremely resistant to killing and patients are left with very few effective therapeutic options.

To address the problem, investigators enrolled 22 patients with relapsed or refractory CD30+ lymphoma into this single-center phase 1/2 trial, 20 of whom were diagnosed with Hodgkin lymphoma (HL). All had active progressive disease at enrollment, and none received bridging therapy. Patients were heavily pretreated, with a median of 7 (range, 1-14) prior lines of therapy. Nine underwent autologous stem cell transplantation (SCT) and 5 received allogeneic SCT.

Eligible patients had relapsed/refractory CD30-positive classical HL, B-cell non-Hodgkin lymphoma, anaplastic large-cell lymphoma, or peripheral T-cell lymphoma that was refractory or intolerant to brentuximab vedotin. They needed to have an ECOG performance status of 2 or below, and adequate renal, hepatic, pulmonary, and cardiac function.

The median age was 40 years (range, 20-75). Most patients were white (68.2%) and male 68.1%).

Patients receive 2 cycles of fludarabine/cyclophosphamide, followed by AFM13-CB NK cells at 3 dose levelsDL1 (106NK/gg), DL2 (107NK/kg), and DL3 (108NK/kg)on day 0 plus 3 weekly intravenous infusions of 200 mg AFM13, a CD30/CD16A bispecific antibody. Nineteen patients completed both planned cycles of treatment.

Nieto and colleagues isolated NK cells from cord blood, then used a mixture of cytokines to activate the cells into a memory-like state, making them more persistent and effective. They then expanded the cells in culture and complexed them with AFM13.

At a median follow-up of 11 months, progression-free survival (PFS) and overall survival (OS) rates across all 3 dose levels were 52% and 81%, respectively. Across all dose levels, 53% of patients experienced CR and 37% had PR. Eleven percent had progressive disease.

Expansion of NK cells occurred immediately after infusion and persisted for 3 weeks.

Investigators established DL3 as the recommend phase 2 dose (RP2D). All 13 (100%) patients treated at this dose level responded to therapy, including eight CRs (62%).Five of those patients were in CR after cycle 1, and 3 additional patients converted from PR to CR after cycle 2, Nieto added.

The median PFS was 67% and the median OS was 93% in the RP2D population.

Investigators did not record any cytokine release syndrome or graft vs host disease (GVHD), or neurotoxicity. Our preliminary results show an excellent tolerability profile, Nieto said.

There was no instance of infusion-related reactions (IRRs) associated with AFM13-NK cells across 40 infusions. There was 1 instance of grade 3 IRR and 4 grade 2 IRRs in 108 infusions of AFM13 alone. Investigators observed no dose limiting toxicities.

Never before in mankind have we seen this approach, really leading to pretty staggering results, Timothy Yap, MBBS, PhD, FRCP, a medical oncologist and associate director of translational research in the Institute for Personalized Cancer Therapy at the University of Texas MD Anderson Cancer Center, said. Everyone can see for themselves how impressive these results are. In addition to that, the actual tolerability profile is truly excellent with no instances of cytokine release syndrome, no neurotoxicity, no GVHD. Truly, truly impressive.

The use of human bone marrow mesenchymal stem cells (hBMSCs) to regenerate and repair bone tissue defects is a complex research field of bone tissue engineering; nevertheless, it is a hot topic. One of the biggest problems is the limited survival and osteogenic capacity of the transplanted cells within the host tissue. Even for hBMSCs with their low immunogenicity, the body will still cause a local immune-inflammatory response directed against the allogeneic cells and thereby reduce the activity of the transplanted cells. Even in the case of successful transplantation, the lack of vascularization at the transplantation site makes it difficult for the transplanted cells to exchange nutrients and metabolic wastes that ultimately affects bone regeneration. In this study, we covalently modified alginate with RGD and QK peptides that were injected subcutaneously into immunocompetent mice. Histological analysis, as well as ELISA techniques, proved that this method is able to provide bioactive stem cell transplant beds containing functionalized biomaterials and vascularized surrounding tissues. Inflammation-related factors, such as IL-2, IL-6, TNF-, and IFN-, around the cell graft beds decreased with time and were lowest at the second week. Then, the hBMSCs were injected into the cell transplantation beds intended to form vascularized bonelike tissues that were evaluated by micro-computed tomography (Micro CT), histological, and immunohistochemical analyses. The results showed that the expression of osteogenesis-related proteins RUNX2, COL1A1, and OPN, as well as the expression of angiogenic factor vWF and cartilage-related protein COL2A1 were significantly upregulated in the hBMSC-derived osteogenic tissue. These results suggest that the stem cell transplantation strategy by constructing bioactive cell transplant beds is effective to enhance the bone regeneration capacity of hBMSCs and holds great potential in bone tissue engineering.

A breakthrough made by Australian researchers might change the way doctors treat a broken or missing bone. Turns out stem cells can turn into bone if certain conditions are met.

Normally, bone can be made only of mesenchymal stem cells (MSCs) which are biologically found in the bone marrow.

Extracting them from there is a difficult and painful procedure while doing so at scale is beyond tricky.

But this could change any moment now after Australian researchers found that stem cells can be converted into bone when a certain type of sound waves are used.

Tests had previously shown that low frequency vibrations were great at inducing cell differentiation but the process took over a week and the results were mixed at best.

Nobody had bothered to look into high frequency sound waves until now. RMIT researchers took a microchip capable of dispersing sound waves in the Mhz range and turned it at MSCs in silicon oil on a culture plate.

The team noticed that after exposing the cells to 10MhZ signals for 10 minutes daily for five days, the markers indicating the bone conversion appeared.

We can use the sound waves to apply just the right amount of pressure in the right places to the stem cells, to trigger the change process, said Leslie Yeo, co-lead researcher on the study. Our device is cheap and simple to use, so could easily be upscaled for treating large numbers of cells simultaneously vital for effective tissue engineering.

This discovery, detailed in the journalSmall, eliminates the need of drugs to make stem cells behave this way. Moreover, the MSCs can be pulled from a variety of places, like fast tissue, not just bone marrow.

By injecting them into the body in case of an injury or disease, they can start working on a new bone faster and more efficient.

Jasper Therapeutics

REDWOOD CITY, Calif., March 31, 2022 (GLOBE NEWSWIRE) -- Jasper Therapeutics, Inc. (NASDAQ: JSPR), a biotechnology company focused on hematopoietic cell transplant therapies, today announced that updated data from the Companys ongoing study of JSP191 as single agent conditioning prior to allogeneic hematopoietic stem cell (HSC) re-transplant in patients with severe combined immunodeficiency (SCID) has been accepted for presentation as a late-breaking poster at the 2022 Clinical Immunology Society (CIS) Annual Meeting, to be held in Charlotte, North Carolina from March 31 to April 3, 2022.

Title: Update: Single-Agent Conditioning with Anti-CD117 Antibody JSP191 Shows Donor Engraftment, Nave Lymphocyte Production, and Clinical Benefit in Patients with Severe Combined Immunodeficiency (SCID)Date and Time: Friday, April 1, 2022, 1:00-2:00 p.m. ET

This updated data indicates that JSP191 at 0.6mg/kg can deplete blood stem cells, leading to long-term donor cell engraftment, immune reconstitution which positively affects the clinical status of SCID patients who suffer from poor T cell and negligible B cell immunity because they failed their first transplant, said Wendy Pang, MD, Ph.D., Senior Vice President of Research and Translational Medicine of Jasper Therapeutics. This population of SCID patients is largely without treatment options and rely on supportive therapies like life long IVIG to provide some level of immune protection. JSP191 based conditioning may provide these patients with the best chance of a safe and successful transplant and reconstituted immune system.

CIS attendees are the primary caregivers for the immune deficient patient population, we are pleased to be able to present this data at the 2022 CIS annual meeting, Ronald Martell, CEO of Jasper. We believe that with our successful clinical efforts, we are one step closer, and uniquely positioned to deliver a targeted non-genotoxic conditioning agent to patients with SCID.

About JSP191

JSP191 is a humanized monoclonal antibody in clinical development as a conditioning agent that blocks stem cell factor receptor signaling leading to clearance of hematopoietic stem cells from bone marrow, creating an empty space for donor or genetically modified transplanted stem cells to engraft. To date, JSP191 has been evaluated in more than 100 healthy volunteers and patients. Three clinical trials for myelodysplastic syndromes (MDS)/acute myeloid leukemia (AML), severe combined immunodeficiency (SCID) and Fanconi anemia are currently enrolling. The Company plans a new study of JSP191 as a second-line therapeutic in lower risk MDS patients in 2022 as well as to a pivotal study in MDS/AML transplant in early 2023. Enrollment in additional studies are planned in patients with sickle cell disease, chronic granulomatous disease and GATA2 MDS who are undergoing hematopoietic cell transplantation.

About Jasper Therapeutics

Jasper Therapeutics is a biotechnology company focused on the development of novel curative therapies based on the biology of the hematopoietic stem cell. The company is advancing two potentially groundbreaking programs. JSP191, an anti-CD117 monoclonal antibody, is in clinical development as a conditioning agent that clears hematopoietic stem cells from bone marrow in patients undergoing hematopoietic cell transplantation. It is designed to enable safer and more effective curative allogeneic hematopoietic cell transplants and gene therapies. In parallel, Jasper Therapeutics is advancing its preclinical mRNA engineered hematopoietic stem cell (eHSC) platform, which is designed to overcome key limitations of allogeneic and autologous gene-edited stem cell grafts. Both innovative programs have the potential to transform the field and expand hematopoietic stem cell therapy cures to a greater number of patients with life-threatening cancers, genetic diseases and autoimmune diseases than is possible today.

ABSTRACT

The exosomes (Exo) had always been considered as transport vectors for microRNA (miRNA). An increasing number of data had clarified the influence of Exo on the cell progression of non-small cell lung cancer (NSCLC). Nevertheless, its specific mechanism had not yet been verified. This work was to explore the potential mechanism of Exo-derived miR-631 targeting and regulating E2F family of transcription factor 2 (E2F2) to repress the malignant behavior of NSCLC cells. Test of microRNA (miR)-631 and E2F2 in NSCLC was performed. BMSCs-Exo that altered miR-631 was co-cultured with NSCLC cells. Detection of the cloning and progression of NSCLC cells was performed. Testification of the targeting of miR-631 with E2F2 was conducted. In vivo experiments were performed to verify the results in vitro. In short, elevation of miR-631 Exo repressed the advancement and phosphatidylinositol 3-kinase/Akt activation of NSCLC cells, while silence of miR-631 was in the opposite. In terms of mechanism, miR-631 exerted the influence via targeting E2F2. The coincident results were obtained in animal models. In brief, BMSC-Exo mediated E2F2 via delivering miR-631 to NSCLC cells to modulate the malignant behavior of NSCLC.

Abstract:

Background:

Objective:To observe the effect of H2O2 induced oxidative stress on autophagy and apoptosis of human bone marrow mesenchymal stem cells (hBMSCs).

Method: The hBMSCs were separated and cultured by density gradient centrifugation combined with adherence method. They were divided into blank group (with medium only), 3-MA (autophagy inhibitor) pretreatment group (with 2 ml of 5 mM 3-MA medium), H2O2 Intervention group (add 2ml medium containing 0.05mM H2O2), H2O2+3-MA treatment group (add 2ml medium containing 5mM 3-MA, then add 2ml medium containing 0.05mM H2O2). DCFH-DA staining was used to detect cellular reactive oxygen species (ROS) levels,and CCK-8 analysis was used to detect the effects of different concentrations (0,50,100,200,400mol/L) of H2O2 on the proliferation of hBMSCs; Monodansylcadaverine(MDC) Fluorescent amine probe staining, Lysosome Red Fluorescent Probe (Lyso-Tracker Red) staining to observe the level of autophagy; Immunofluorescence staining to detect the expression of LC3A/B; Flow cytometry (Annexin V/PI) to detect cell apoptosis Circumstances; Protein chip detection of autophagy-related proteins; Western blot detection of Beclin1, mTOR, p-mTOR, LC3A/B, and Cleaved caspase-3 protein expression.

Result: After treating hBMSCs with different concentrations of H2O2 (0,50,100,200,400mol) for 24h ,48h, and 72h, with the increase of H2O2 concentration, the cell proliferation ability decreased; while with the extension of time, the cell proliferation ability increased not significantly; 50mol cell proliferation ability is the strongest. Compared with the blank group and 3-MA group, the H2O2 intervention group increased the level of intracellular ROS, increased autophagosomes, and significantly decreased the apoptosis rate; up-regulated Beclin1, mTOR, LC3A/B and Cleaved caspase-3 protein expression, and down-regulated p-mTOR Protein expression level. Compared with the autophagy inhibitor 3-MA group, the H2O2+3-MA group increased the level of intracellular ROS, increased autophagosomes, and did not significantly increase the apoptosis rate; up-regulated the protein expression of Beclin1, mTOR, LC3A/B and Cleaved caspase-3 Down-regulate the expression of p-mTOR protein.

Conclusion: H2O2 can induce hMSCs to produce oxidative stress response. Under oxidative stress conditions, hMSCs can promote protective autophagy and reduce cell apoptosis or the level of apoptosis caused by excessive autophagy.
