Jasper Therapeutics Announces Upcoming Data Presentation on Lead Program, JSP191, at 61st American Society of Hematology (ASH) Annual Meeting &…

JSP191, a humanized antibody targeting CD117, is designed to replace or reduce the toxicity of chemotherapy and radiation therapy as a conditioning regimen to prepare patients for hematopoietic cell transplantation. The Phase 1 clinical trial is evaluating JSP191 as a conditioning agent to enable stem cell transplantation in patients with severe combined immunodeficiency (SCID) who received a prior stem cell transplant that had poor outcomes.

Life-threatening disorders such as SCID, and other conditions including autoimmune diseases and hematologic cancers, can be cured by hematopoietic cell transplantation, and those with certain genetic diseases can be cured with stem cell-directed gene therapies. However, the number of patients who can benefit from these approaches is limited because of the severe toxicity of the chemotherapy used for pre-transplant conditioning that is needed to allow room in the bone marrow for the stem cells to engraft, said Judith Shizuru, M.D., Ph.D., co-founder and member of the Board of Directors of Jasper Therapeutics. We are encouraged by the initial Phase 1 study results of JSP191 in these fragile patients with SCID and plan to expand clinical development of this antibody beyond patients with SCID. We expect to initiate clinical trials of JSP191 in 2020 to evaluate it as a conditioning agent in patients undergoing hematopoietic cell therapy for acute myeloid leukemia, myelodysplastic syndrome and Fanconi anemia, and IND-enabling studies for sickle cell disease and autoimmune indications.

About Stem Cell Transplantation

Blood-forming, or hematopoietic, stem cells are cells that reside in the bone marrow and are responsible for the generation and maintenance of all blood and immune cells. These stem cells can harbor inherited or acquired abnormalities that lead to a variety of disease states, including immune deficiencies, blood disorders or hematologic cancers. Successful transplantation of hematopoietic stem cells is the only cure for most of these life-threatening conditions. Replacement of the defective or malignant hematopoietic stem cells in the patients bone marrow is currently achieved by subjecting patients to toxic treatment with radiation and/or chemotherapy that cause DNA damage and lead to short- and long-term toxicities, including immune suppression and prolonged hospitalization. As a result, many patients who could benefit from a stem cell transplant are not eligible. New approaches that are effective but have minimal to no toxicity are urgently needed so more patients who could benefit from a curative stem cell transplant could receive the procedure.

Safer and more effective hematopoietic cell transplantation regimens could overcome these limitations and enable the broader application of hematopoietic cell transplants in the cure of many disorders. These disorders include hematologic cancers (e.g., myelodysplastic syndrome [MDS] and acute myeloid leukemia [AML]), autoimmune diseases (e.g., lupus, rheumatoid arthritis, multiple sclerosis and Type 1 diabetes), and genetic diseases that could be cured with genetically-corrected autologous stem cells (e.g., severe combined immunodeficiency syndrome [SCID], sickle cell disease, beta thalassemia, Fanconi anemia and other monogenic diseases).

About JSP191

JSP191 (formerly AMG191) is a first-in-class humanized monoclonal antibody in clinical development as a conditioning agent that clears hematopoietic stem cells from bone marrow. JSP191 binds to human CD117, a receptor for stem cell factor (SCF) that is expressed on the surface of hematopoietic stem and progenitor cells. The interaction of SCF and CD117 is required for stem cells to survive. JSP191 blocks SCF from binding to CD117 and disrupts critical survival signals, causing the stem cells to undergo cell death and creating an empty space in the bone marrow for donor or gene-corrected transplanted cells to engraft.

Preclinical studies have shown that JSP191 as a single agent safely depletes normal and diseased hematopoietic stem cells, including in an animal model of MDS. This creates the space needed for transplanted normal donor or gene-corrected hematopoietic stem cells to successfully engraft in the host bone marrow. To date, JSP191 has been evaluated in more than 80 healthy volunteers and patients. It is currently being evaluated as a sole conditioning agent in a Phase 1 dose-escalation trial to achieve donor stem cell engraftment in patients undergoing hematopoietic cell transplant for SCID, which is curable only by this type of treatment. For more information about the design of the clinical trial, visit http://www.clinicaltrials.gov (NCT02963064). Clinical development of JSP191 will be expanded to also study patients with AML or MDS who are receiving hematopoietic cell transplant.

The Uncertainty of Regulating 3D Organ Printing – The Regulatory Review

Policymakers around the world are determining how to apply existing regulations to 3D organ printing.

When Selena Gomez suffered from Lupus, her best friend Francia Raisa donated her kidney to her, saving Gomezs life. For decades, people just like Gomez have escaped death due to heroic organ donations, either from living or deceased donors.

Today, 3D printingalso referred to as 3DPmay revolutionize the practice of organ donation. Although 3D printing is currently used to make jewelry, food, and art, it may soon be used for medical solutions such as organ donations and bionic limbs.

As a result, policymakers around the world seek increased regulation of 3DP organs. Yet 3D bioprinting does not clearly fit into existing regulatory frameworks.

Since bioprinting generally falls within the regulatory domain of regenerative medicine, medical devices, and biologic drugs, regulators face the challenge of applying existing rules to this uncertain field. As of now, it is unclear whether policymakers can effectively regulate bioprinting under existing regulations, or if a new, specific regulatory process will be necessary.

In determining how to regulate 3D organ printing, policymakers must juggle many possible concerns. Since the technology is still developing, a lot of uncertainty remains about what the actual risks and ethical concerns are. For example, one ethical concern is that 3DP organs may be available to wealthy people only, while less affluent individuals will be blocked out from using these organs.

Another concern is safety. Since 3DP may require stem-cell technology, and the patients own cells may be used for replication, it is difficult to assess the safety risks. Stem-cell therapy cannot be tested on a large sample of healthy people, which limits effective clinical analysis. Also, 3DP biotechnology may open up new uses beyond 3DP organs, such as enhancement of human capacities for military use. Developers could use the technology to make military officers or even terrorists less vulnerable to injury in battle, but this would open up a whole new challenge for law enforcement and national security.

The U.S. Food and Drug Administration (FDA) focuses on the regulation of 3D printed organs. FDA so far has only released guidance on 3DP, and the recommendations do not cover bioprinting.

A significant concern in the United States is that 3D printed organs do not fit into any clear category of law. First, they are not organs because they are not born alive at any stage of development. Second, they are not drugs because drugs are used orally rather than through an invasive surgery, and drugs are primarily meant to relieve illness while donated organs may completely cure an illness.

Some policymakers in the United States propose regulating 3DP organs as a biological product, defined as a virus, therapeutic serum, toxinor analogous productapplicable to the prevention, treatment, or cure of a disease or condition of human beings.

Research company Biogelx suggests that biological products may be a promising category for printed organs. Within biological products, a 3DP organ is comparable to proteins because to print the organ, clinicians replicate healthy human cells, which include such proteins, says Biogelx. Although existing regulatory frameworks often compare 3DP organs to medical devices, Biogelx asserts that these organs should not be regulated as medical devices. Medical devices are not made of biological material and are often metal or plastic devices that help an individuals standard of life, but 3DP organs are different since they cause a chemical reaction in the body and have the purpose of wholly replacing an existing organ, says Biogelx.

International policymakers are also struggling to find a sufficient regulatory framework. In Canada, Health Canada released draft guidance last year to develop regulations for medical device manufacturers working towards bioprinting. Health Canada has several concerns about bioprinting, and it suggests that manufacturers looking for bioprinting licenses should be required to submit information regarding the use of additives in materials, the verification of the software for the bioprinting design, the method of sterilizing the machines, and the process of safe removal and reuse of bioprinting materials and residues.

Finally, Europes 3DP health technology is regulated by the European Medical Devices Directive, the Active Implantable Medical Devices Directive, and the Invitro Diagnostic Medical Devices Directive. The Medical Devices Directive categorizes bioprinting devices into several risk classes. Across the different classes, devices ranked as higher risk are subjected to third party assessment and more stringent requirements for clinical data. The highest risk class, implantable devices such as 3D organs, requires an independent design dossier review. A design dossier assesses risk, evaluates clinical data, and demonstrates the technologys compliance with regulations and requirements.

Although 3D printing of organs is right around the corner, policymakers around the world lack the information necessary to make regulatory decisions in this space. Different countries have different approaches, but many of the leading nations in 3DP share similar concerns. With more information, regulators will have to decide if existing regulatory frameworks can adequately address the safety concerns of 3D printed organs.

Mustang Bio Announces Updated Clinical Data on MB-107 Lentiviral Gene Therapy for Patients with X-Linked Severe Combined Immunodeficiency -…

MB-107 preceded by low-dose busulfan conditioning continues to be well tolerated and results in development of functional immune system in newly diagnosed infants with XSCID

Enhanced transduction procedure is demonstrating improvements in older patients with XSCID who received prior hematopoietic stem cell transplantation

Data presented by St. Jude Childrens Research Hospital and National Institutes of Health at 61st American Society of Hematology Annual Meeting

NEW YORK, Dec. 09, 2019 (GLOBE NEWSWIRE) -- Mustang Bio, Inc. (Mustang) (NASDAQ: MBIO), a clinical-stage biopharmaceutical company focused on translating todays medical breakthroughs in cell and gene therapies into potential cures for hematologic cancers, solid tumors and rare genetic diseases, announced today that updated Phase 1/2 clinical data for MB-107 lentiviral gene therapy for X-linked severe combined immunodeficiency (XSCID) were presented on Saturday by St. Jude Childrens Research Hospital (St. Jude) and today by the National Institutes of Health at the 61st American Society of Hematology (ASH) Annual Meeting.

MB-107 is currently being assessed in two Phase 1/2 clinical trials for XSCID: the first in newly diagnosed infants under the age of two at St. Jude, and the second in patients over the age of two who have received prior hematopoietic stem cell transplantation at the National Institutes of Health. Under a licensing partnership with St. Jude, Mustang intends to develop the lentiviral gene therapy for commercial use as MB-107. The U.S. Food and Drug Administration (FDA) granted Regenerative Medicine Advanced Therapy (RMAT) designation to MB-107 for the treatment of XSCID in August 2019.

Manuel Litchman, M.D., President and Chief Executive Officer of Mustang, said, The updated clinical data presented at the 2019 ASH Annual Meeting underscore the curative potential of MB-107 for newly diagnosed infants with XSCID, as well as its meaningful impact on older XSCID patients who received prior hematopoietic stem cell transplantation. St. Jude recently received the 2019 Smithsonian Magazine American Ingenuity Award for development of the lentiviral gene therapy, highlighting its potential to have an impact on this devastating disease. We are excited to be working with St. Jude and NIH to advance MB-107 and look forward to transferring the IND from St. Jude to Mustang in the first quarter of 2020.

Lentiviral Gene Therapy with Low Dose Busulfan for Infants with X-SCID Results in the Development of a Functional Normal Immune System: Interim Results of an Ongoing Phase I/II Clinical Study (Abstract Number: 2058)Poster presentation: Ewelina Mamcarz, M.D., Department of Bone Marrow Transplantation and Cellular Therapy, St. Jude Childrens Research Hospital, Memphis, TN, USA

Interim data from the multicenter Phase 1/2 clinical trial for infants under the age of two treated with the lentiviral gene therapy preceded by low exposure-targeted busulfan conditioning were published in the New England Journal of Medicine. Updated data presented at the 2019 ASH Annual Meeting include three more patients (n=11), 8 months additional median follow up (23.6 months; range: 1.5 to 33.9 months), more extensive analysis of T and B cell functional recovery, and detailed vector integration site studies.

Data Highlights:

The results from treatment with low-dose busulfan conditioning and the novel lentiviral gene therapy in newly diagnosed infants with XSCID continue to be very promising, said Dr. Mamcarz. We are pleased that the therapy has been well tolerated and all patients with a follow up of more than 3 months recovered from pre-existing infections, are off protective isolation and prophylactic antimicrobials, and have normal growth in respect to height and weight. This reinforces our belief that the lentiviral gene therapy has the potential to be an attractive alternative to current XSCID therapies.

Enhanced Transduction Lentivector Gene Therapy for Treatment of Older Patients with X-Linked Severe Combined Immunodeficiency (Abstract Number: 608)Oral presentation: Harry Malech, M.D., Laboratory of Clinical Immunology and Microbiology, National Institute of Allergy and Infectious Diseases, National Institutes of Health (NIH), Bethesda, MD, USA

Early outcome data for five older children and young adults with XSCID who received the lentivector (also known as lentiviral) gene therapy as salvage therapy after having previously received haplo-identical hematopoietic stem cell transplantation (HSCT) as infants without chemotherapy-based conditioning were previously reported and published in Science Translational Medicine. By 2016, three additional patients were treated, and the cohort of eight patients (referred to as Cohort A) has now been followed for 3 to 7 years. Among Cohort A, gradual clinical benefit in the clearance of chronic norovirus and associated improved abdominal complaints, malabsorption, growth and IgG production were observed, and four patients were able to cease immunoglobulin replacement therapy.

While the results were positive, the relatively inefficient transduction of hematopoietic stem/progenitor cells (HSPCs) required large quantities of vector. This resulted in relatively low VCN in myeloid cells in some patients, with delayed immune cell recovery and persistent clinical disease, especially in the last patient treated (patient 8). To address this, NIH developed a refined enhanced transduction (ET) procedure consisting of a single overnight transduction after 48 hours pre-stimulation in cytokines (Stem cell factor, Thrombopoietin, Flt3-ligand; 100ng/mL) and incorporated transduction enhancers LentiBoost 1:100 and dimethyl prostaglandin 2 (dmPGE2; 1uM).

The presentation at the 2019 ASH Annual Meeting included data from six patients (referred to as Cohort B) treated by NIH, including re-treatment of patient 8. The patients, who were aged 12 to 36, had significant problems with donor T cell infiltration of liver, bone marrow and kidneys, and were nearly absent of B and NK cells. The enhanced transduction procedure achieved much greater transduction efficiencies than were observed in Cohort A, with greater than 10-fold less vector, and resulted in faster immune reconstitution and more significant clinical benefit by 3 months.

We are encouraged by the significantly improved measures of early clinical outcomes from lentivector gene therapy in older children and young adults with XSCID using an enhanced transduction procedure with the addition of LentiBoost and dmPGE2, said Dr. Malech. Notably, we have seen an early appearance of B and NK cells at much higher levels in Cohort B than we previously observed in Cohort A, even at years after treatment. We look forward to continuing to closely monitor patients and report outcomes.

MacroGenics Presents Flotetuzumab Data in Patients with Primary Induction Failure and Early Relapsed Acute Myeloid Leukemia at the 2019 ASH Annual…

Rockville, MD, Dec. 09, 2019 (GLOBE NEWSWIRE) --

MacroGenics, Inc. (NASDAQ: MGNX), a clinical-stage biopharmaceutical company focused on discovering and developing innovative monoclonal antibody-based therapeutics for the treatment of cancer, today announced updated results from a Phase 1/2 dose expansion study of flotetuzumab, an investigational, bispecific CD123 x CD3 DART molecule in patients with primary induction failure and early relapsed acute myeloid leukemia (AML). The data were presented in an oral session at the 61st Annual Meeting of the American Society of Hematology (ASH) in Orlando, FL, taking place December 7-10, 2019.

Patients with AML who have failed primary induction therapy or relapsed early after an initial response represent a significant unmet medical need. A remission rate of 32% observed in the ongoing study of flotetuzumab in this extremely challenging patient population is noteworthy, said Geoffrey Uy, M.D., Associate Professor, Department of Medicine, Division of Oncology at the Washington University School of Medicine in St. Louis. Importantly, by implementing a lead-in dosing schedule for flotetuzumab, as well as early intervention with tocilizumab in this study, we were able to mitigate cytokine release syndrome, known to be associated with T-cell engagers.

In the Phase 1/2 (NCT02152956) open-label, dose expansion study, 30 patients classified as primary induction failure or early relapsed AML who had received a median of four prior therapies were treated with flotetuzumab at the recommended phase 2 dose (RP2D) of 500 ng/kg/day by continuous infusion. Data were reported as of the cut-off date of November 1, 2019. The study is currently ongoing, with additional patients being enrolled.

Responses, including complete remission (CR), CRh (CR with partial hematological recovery) and CRi (CR with incomplete hematological improvement) per a modified International Working Group (IWG) Response Criteria for AML, are summarized in the table below. Four responders received allogeneic hematopoietic stem cell transplantation as consolidation therapy and remain in remission after 6 to 21 months.

The most common treatment-related adverse event (TRAE) was infusion-related reaction/cytokine release syndrome (IRR/CRS) that occurred in all (30/30) patients. However, most CRS events observed were of short duration and mild to moderate (grade 1 or 2) in severity, with only one grade 3 event reported in one patient.

Based on the encouraging data from this study, and pending anticipated discussions with the FDA in the first half of 2020, we are planning for a potential registration-enabling study of flotetuzumab in this high unmet need population of patients with refractory AML, who have limited treatment options, said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics.

A separate oral presentation described translational research that showed an inflammatory (IFN--related) gene expression signature in a subset of patients with AML that correlated with a lack of response to induction chemotherapy. Furthermore, the same gene signature was associated with patients more likely to respond to flotetuzumab, supporting the mechanism being exploited by this molecule. In addition, AML patients with an immune-infiltrated tumor micro-environment show high expression of immune checkpoint molecules, including PD-L1, which provides a scientific rationale for combining flotetuzumab with checkpoint blockade as a potential mechanism for enhanced anti-leukemic activity. MacroGenics has initiated a study combining flotetuzumab with MGA012, an anti-PD-1 antibody, given the strong preclinical and translational data that indicate the combination may enhance CD123-directed T cell killing.

About Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a hematopoietic stem cell malignancy characterized by differentiation arrest and uncontrolled clonal proliferation of neoplastic precursors that prevent normal bone marrow hematopoiesis. Nearly 20,000 new cases of AML are diagnosed in the U.S. each year, with a median age of 69 years at diagnosis. Approximately 40-50% of newly diagnosed patients fail to achieve a complete remission with intensive induction therapy (primary induction failure) or experience disease recurrence after a short remission duration (<6 months; early relapsed). A very small number of these patients are expected to respond to salvage therapy. In addition, although new targeted agents have been approved for the treatment of frontline or relapsed/refractory AML in recent years, approximately 50% of patients have no known targetable mutations.

About Flotetuzumab

Flotetuzumab (also known as MGD006) is a clinical-stage molecule that recognizes both CD123 and CD3. CD123, the interleukin-3 receptor alpha chain, has been reported to be over-expressed on cancer cells in AML and other hematologic malignancies. The primary mechanism of action of flotetuzumab is believed to be its ability to redirect T lymphocytes to kill CD123-expressing cells. To achieve this, the DART molecule combines a portion of an antibody recognizing CD3, an activating molecule expressed by T cells, with an arm that recognizes CD123 on the target cancer cells.

Flotetuzumab is currently being evaluated in the U.S. and Europe in a Phase 1/2 dose expansion study designed to assess the safety, tolerability, and initial anti-leukemic activity of the molecule in patients with relapsed/refractory AML. The U.S. Food and Drug Administration has granted orphan drug designation to flotetuzumab for the treatment of AML. A Phase 1/2 study in combination with MGA012, a proprietary anti-PD-1 monoclonal antibody, in patients with relapsed/refractory AML is being conducted ex-U.S. MGA012 (also known as INCMGA00012) was exclusively licensed to Incyte Corporation in 2017 under a global collaboration and license agreement; MacroGenics retains the right to develop its pipeline molecules with MGA012. MacroGenics retains global development and commercialization rights to flotetuzumab.

About ADA-SCID and OTL-101Severe combined immune deficiency due to adenosine deaminase deficiency (ADA-SCID) is a rare, life-threatening, inherited disease of the immune system caused by mutations in the ADA gene resulting in a lack of, or minimal, immune system development.1-4 The first symptoms of ADA-SCID typically manifest during infancy with recurrent severe bacterial, viral and fungal infections and overall failure to thrive, and without treatment the condition can be fatal within the first two years of life. The incidence of ADA-SCID is currently estimated to be one in 500,000 live births in the United States and between one in 200,000 and one in 1 million in Europe.3 OTL-101 is an autologous, ex vivo, hematopoietic stem cell-based gene therapy for the treatment of patients diagnosed with ADA-SCID being investigated in multiple clinical trials in the United States and Europe, including a registrational trial at the University of California, Los Angeles (UCLA). OTL-101 has received orphan drug designation from the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of ADA-SCID, and Breakthrough Therapy Designation from the FDA.

About WAS and OTL-103Wiskott-Aldrich Syndrome (WAS) is a life-threatening inherited immune disorder characterized by autoimmunity and abnormal platelet function and manifests with recurrent, severe infections and severe bleeding episodes, which are the leading causes of death in this disease. Without treatment, the median survival for WAS patients is 14 years of age. Treatment with stem cell transplant carries significant risk of mortality and morbidities. OTL-103 is an ex vivo, autologous, hematopoietic stem cell-based gene therapy developed for the treatment of WAS that Orchard acquired from GSK in April 2018 and has been developed at the San Raffaele-Telethon Institute for Gene Therapy (SR-Tiget) in Milan, Italy. The global incidence of WAS is estimated to be about 100-260 births per year, with a global prevalence of 2,900-4,700 patients.

About MPS-I and OTL-203Mucopolysaccharidosis type I (MPS-I) is a rare inherited neurometabolic disease caused by a deficiency of the IDUA (alpha-L-iduronidase) lysosomal enzyme required to break down glycosaminoglycans (also known as GAGs or mucopolysaccharides). The accumulation of GAGs across multiple organ systems results in the symptoms of MPS-I including neurocognitive impairment, skeletal deformity, loss of vision and hearing, hydrocephalus, and cardiovascular and pulmonary complications. MPS-I occurs at an overall estimated frequency of one in every 100,000 live births.5 There are three subtypes of MPS-I; approximately 60 percent of MPS-I patients have the severe Hurler subtype and, when untreated, these patients rarely live past the age of 10.Id Treatment options for MPS-I include hematopoietic stem cell transplant and chronic enzyme replacement therapy, both of which have significant limitations. Though early intervention with enzyme replacement therapy has been shown to delay or prevent some clinical features of the condition, it has only limited efficacy on neurological symptoms. OTL-203 is an ex vivo, autologous, hematopoietic stem cell-based gene therapy being studied for the treatment of MPS-I. Orchard was granted an exclusive worldwide license to intellectual property rights to research, develop, manufacture and commercialize the gene therapy program for the treatment of MPS-I developed by the San Raffaele-Telethon Institute for Gene Therapy in Milan, Italy.

About Orchard Orchard Therapeutics is a fully integrated commercial-stage biopharmaceutical company dedicated to transforming the lives of patients with serious and life-threatening rare diseases through innovative gene therapies.

Orchards portfolio of ex vivo, autologous, hematopoietic stem cell (HSC) based gene therapies includes Strimvelis, a gammaretroviral vector-based gene therapy and the first such treatment approved by the European Medicines Agency for severe combined immune deficiency due to adenosine deaminase deficiency (ADA-SCID). Additional programs for neurometabolic disorders, primary immune deficiencies and hemoglobinopathies are all based on lentiviral vector-based gene modification of autologous HSCs and include three advanced registrational studies for metachromatic leukodystrophy (MLD), ADA-SCID and Wiskott-Aldrich syndrome (WAS), clinical programs for X-linked chronic granulomatous disease (X-CGD), transfusion-dependent beta-thalassemia (TDT) and mucopolysaccharidosis type I (MPS-I), as well as an extensive preclinical pipeline. Strimvelis, as well as the programs in MLD, WAS and TDT were acquired by Orchard from GSK in April 2018 and originated from a pioneering collaboration between GSK and the San Raffaele Telethon Institute for Gene Therapy in Milan, Italy initiated in 2010.

Orchard currently has offices in the UK and the U.S., including London, San Francisco and Boston.
