Fate Therapeutics Soars as Much as 45.8% After Giving Investors What They Wanted – The Motley Fool

What happened

Shares of Fate Therapeutics (NASDAQ:FATE) jumped as much as 45.8% today after the company gave investors what they've long craved: data.

The company is developing novel immunotherapies based on natural killer (NK) cells, whereas most drug candidates in the industry's pipeline rely on T cells. NK cells have numerous inherent advantages but have delivered mixed clinical results to date for competitors, so investors approached the pharma company with caution. That all changed today.

Fate Therapeutics is making six presentations at the Annual Meeting of the American Society of Hematology (ASH). The first handful was made over the weekend and show that the company's was to cellular medicines has promise.

As of 12:50 p.m. EST, the stock had settled to a 44.4% gain.

The cellular medicine innovator provided updates for three drug candidates:

Fate Therapeutics reported that FT516 wiped out any signs of cancer in the first AML patient to receive treatment. A follow-up from the first patient with high-risk diffuse large B-cell lymphoma (DLBCL) is pending.

Meanwhile, the first 12 patients to receive FT500 showed little to no sign that their bodies were rejecting treatment. That's a concern for cellular medicines, which are at risk of being (correctly) identified as foreign cells by the recipient's immune system, and it's one of the obstacles NK cells inherently overcome. A separate, smaller population of patients in the study that received only FT500 achieved stable disease at best, but all of the individuals have advanced cancers.

The preclinical update for FT596 was only in mice, so investors can't really get excited yet. Studies show that when administered as a monotherapy, the asset achieved comparable response rates in lymphoma to CAR-T cells. That suggests it may have the same activity as the current best-in-class treatment in addition to the advantages of NK cells. A combination of FT596 and rituximab demonstrated potent tumor clearance, again in a preclinical model. The company expects to begin clinical trials in early 2020.

Fate Therapeutics ended September with $303 million in cash following a large public stock offering made in the third quarter of 2019. Therefore, investors might not expect the business to turn back to dilutive fundraising efforts despite its soaring stock price, although it cannot be ruled out. The company has a whopping 13 programs in preclinical and clinical development. It could be on the lookout for a well-funded partner or two, but it could also tap the public markets again to pursue a go-it-alone strategy. No matter the course ahead, this cellular medicine pioneer is starting to show that its ambitions might not be misplaced.

Blinatumomab Instead of Chemo in Young Patients With Relapsed ALL – Medscape

ORLANDO, Florida In young patients who experience relapse after chemotherapy for B-cell acute lymphoblastic leukemia (B-ALL), the novel agent blinatumomab (Blincyto, Amgen) can be used instead of intensive chemotherapy to try to achieve a second remission, say experts.

In fact, blinatumomab should be the new standard of care in these patients because it yielded better overall survival, was less toxic, and allowed more patients to proceed to transplant, said Robert A. Brodsky, MD, professor of medicine and director of the Division of Hematology at Johns Hopkins School of Medicine in Baltimore, Maryland.

Brodsky was commenting on new data presented in a late-breaking abstract (LBA1) here at the American Society of Hematology (ASH) 2019, for which he holds the role of secretary.

These results are "truly practice changing," he told journalists at a press briefing.

Cure rates for B-ALL in children and adolescents and young adults (AYAs) are high, but for the small group of patients who experience relapse (about 15%), the prognosis is poor.

When relapse occurs in these patients, "it's real problem," Brodsky explained. "At that point, the major emphasis is trying to get them back into full remission and get them to a transplant," he continued, "but it's very hard to get these patients back into remission."

The standard treatment approach for these patients includes intensive chemotherapy. In the new study, this was compared to monotherapy with blinatumomab, which is described as a bi-specific T-cell engager antibody.

The results were presented by Patrick A. Brown, MD, from the Division of Pediatric Oncology at the Sidney Kimmel Comprehensive Cancer Center, Johns Hopkins University.

The Children's Oncology Group Study AALL1331 trial was conducted in 208 children and AYA patients with B-ALL after a first relapse. Median follow-up was 1.4 years.

Blinotumumab was superior in achieving both disease-free survival (59.3 5.4% at 2 years vs 41% 6.2% at 2 years with chemo; P = .05) and overall survival (79.4 4.5% at 2 years vs 59.2 6% at 2 years with chemo; P = .05).

In addition, more patients who received blinotumumab subsequently underwent transplant (79% vs 45% with chemo; P < .0001).

The drug was also better tolerated than chemotherapy, causing fewer and less severe toxicities, including fewer cases of grade 3+ infection, sepsis, and mucositis.

Brown concluded that for children and AYA patients with high- or intermediate-risk first relapse of B-ALL, blinatumomab is superior to standard chemotherapy as post-reinduction consolidation prior to transplant, resulting in fewer and less severe toxicities, higher rates of minimum residual disease response, greater likelihood of proceeding to hematopoietic stem cell transplant, and improved disease-free and overall survival.

Brown told Medscape Medical News that blinotumomab already has conditional approval from the US Food and Drug Administration for use in relapsed ALL in both adults and children, but thatapproval was based on clinical trial data in adults. This is now the definitive trial in children and AYAs, and it should support full approval forthis indication, he said.

Brown has relationships with Novartis, Servier, and Jazz. Many coauthors also have relationships with pharmaceutical companies. Brodsky has relationships with Achillion, Alexion, and UpToDate.

Gamida Cell Announces Results from Phase 1 Study of GDA-201 and New Mechanism of Action Data at ASH 2019 Annual Meeting – Business Wire

BOSTON--(BUSINESS WIRE)--Gamida Cell Ltd. (Nasdaq: GMDA), an advanced cell therapy company committed to finding cures for blood cancers and serious blood diseases, today announced updated results from a Phase 1 clinical study of GDA-201, an investigational, natural killer (NK) cell-based cancer immunotherapy for the treatment of patients with non-Hodgkin lymphoma (NHL) and multiple myeloma (MM), at the 61st Annual Meeting of the American Society of Hematology (ASH), which is being held December 710 in Orlando, FL. Data from 22 patients in the ongoing study showed GDA-201 in combination with monoclonal antibodies was generally well tolerated and demonstrated early evidence of clinical activity in heavily pre-treated patients, including five complete responses observed among nine patients with NHL. Gamida Cell plans to initiate a Phase 1/2 multi-dose, multi-center study of GDA-201 in patients with NHL in 2020.

NK cells are increasingly recognized as a potential breakthrough approach in immunotherapy, and the data reported today provide early evidence that GDA-201 has the potential to be an important new treatment option, said Veronica Bachanova, M.D., Ph.D., Associate Professor of Medicine in the Division of Hematology, Oncology and Transplantation at the University of Minnesota and principal investigator of the study through the Masonic Cancer Center. Given the population of heavily pre-treated patients with advanced disease, its particularly encouraging to witness multiple complete responses. I look forward to the continued development of this investigational therapy.

New research was also presented today on the mechanism of action of Gamida Cells NAM-based cell expansion platform, which is designed to enhance the number and functionality of allogeneic donor cells. These data provide further scientific rationale for the favorable stem cell engraftment and patient outcomes observed in the Phase 1/2 clinical study of omidubicel, the companys advanced cell therapy currently in Phase 3 clinical development as a potential life-saving treatment option for patients in need of an allogeneic bone marrow transplant.

These mechanism of action data reinforce the transformative potential of our NAM therapeutic platform, which can be used to expand multiple cell types. Specifically for omidubicel, this research suggests that NAM modulates certain gene expression pathways that, collectively, mimic the hypoxic environment of the bone marrow to help preserve stem cell function and long-term engraftment ability, said Tracey Lodie, Ph.D., chief scientific officer of Gamida Cell. We expect to build on our findings by characterizing the metabolites produced when we expand stem cells to make omidubicel, and we are also beginning to conduct similar mechanism of action studies with GDA-201.

GDA-201 Phase 1 Clinical Data Presented at ASH

The oral presentation, Results of a Phase 1 Trial of GDA-201, Nicotinamide-Expanded Allogeneic Natural Killer Cells (NAM-NK) in Patients with Refractory Non-Hodgkin Lymphoma (NHL) and Multiple Myeloma (MM) (Abstract #777), described data from the Phase 1 clinical study of GDA-201 in heavily pre-treated patients with advanced NHL and MM. Twenty-two patients were enrolled in the study, including nine patients with NHL and 13 patients with MM. Of these 22 patients, all were evaluable for safety and 21 were evaluable for response (NHL = 9; MM = 12).

In the study, cell therapy using GDA-201 with monoclonal antibodies was generally well tolerated and demonstrated early evidence of clinical activity. Of the nine patients with NHL, five achieved a complete response and one achieved a partial response. Among the patients with MM, one patient achieved a complete response, and five patients achieved stable disease.

GDA-201 was generally well tolerated, with no graft vs. host disease (GvHD), no tumor lysis syndrome, no neurotoxicity and no marrow aplasia observed. No dose limiting toxicities were observed. Hypertension and hematologic events were the most common Grade 3/4 adverse events observed. Most non-hematologic toxicities were attributed to cyclophosphamide/fludarabine, which was used as a pre-conditioning treatment.

NAM Therapeutic Platform Mechanism of Action Data Presented at ASH

The poster presentation, Nicotinamide (NAM) Modulates Transcriptional Signature of Ex Vivo Cultured UCB CD34+ Cells (Omidubicel) and Preserves Their Stemness and Engraftment Potential (Abstract #3718), included transcriptome, transcription factor, and pathway analysis to elucidate the pathways leading to the preservation of engraftment after ex vivo expansion of CD34+ hematopoietic stem cells derived from umbilical cord blood (the starting point for omidubicel) compared to CD34+ cells grown in the absence of NAM.

Analyses showed that the presence of NAM reduced the expression of genes involved in the production of reactive oxygen and nitrogen species, suggesting that cell stress was minimized during expansion. In addition, NAM also decreased growth factor pathways responsible for activation and differentiation of hematopoietic stem cells, suggesting NAM expanded cells while keeping them in an undifferentiated state. The presence of NAM also led to a decrease in the expression of genes responsible for matrix-metallo proteinase secretion, simulating the microenvironment of the bone marrow. Additionally, NAM led to an increased expression of telomerase genes, which is believed to enable cells to remain in a more quiescent, stem-like state. These data provide further scientific rationale for the favorable stem cell engraftment and patient outcomes that were observed in the Phase 1/2 clinical study of omidubicel.

About GDA-201GDA-201 (formerly known as NAM-NK) is being developed as an innate natural killer (NK) cell immunotherapy for the treatment of hematologic and solid tumors in combination with standard-of-care antibody therapies. NK cells have the ability to kill tumor cells, representing a novel immunotherapeutic approach to cancer treatment. GDA-201 is designed to address key limitations of NK cells by increasing the cytotoxicity and in vivo retention and proliferation in the bone marrow and lymphoid organs of NK cells expanded in culture. GDA-201 is in Phase 1 development in patients with refractory non-Hodgkin lymphoma and multiple myeloma.1 For more information on the clinical study of GDA-201, please visit http://www.clinicaltrials.gov.

About OmidubicelOmidubicel (formerly known as NiCord), the companys lead clinical program, is an advanced cell therapy under development as a potential life-saving allogeneic hematopoietic stem cell (bone marrow) transplant solution for patients with hematologic malignancies (blood cancers). Omidubicel is the first bone marrow transplant product to receive Breakthrough Therapy Designation from the U.S. Food and Drug Administration and has also received Orphan Drug Designation in the U.S. and EU. In a Phase 1/2 clinical study, omidubicel demonstrated rapid and durable time to engraftment and was generally well tolerated.2 A Phase 3 study evaluating omidubicel in patients with leukemia and lymphoma is ongoing in the U.S., Latin America, Europe and Asia.3 Omidubicel is also being evaluated in a Phase 1/2 clinical study in patients with severe aplastic anemia.4 The aplastic anemia investigational new drug application is currently filed with the FDA under the brand name CordIn, which is the same investigational development candidate as omidubicel. For more information on clinical trials of omidubicel, please visit http://www.clinicaltrials.gov.

GDA-201 and omidubicel are investigational therapies, and their safety and efficacy have not been evaluated by the U.S. Food and Drug Administration or any other health authority.

AgeX Therapeutics Issues Year-End Letter to Shareholders – BioSpace

The letter follows.

Dear AgeX Stockholders,

In this, our first year as a public company, we have built a foundation for a revolutionary company in the fields of cell therapy and tissue regeneration. To date, conventional pharmaceutical approaches to the chronic degenerative conditions associated with aging have provided little benefit, often only offering relief from the symptoms of disease, rather than targeting underlying disease processes. Our belief is that this is about to change through harnessing the power of new cellular and molecular technologies. We aim to lead this coming revolution with our pioneering technologies which could generate and deliver new cells to patients through our cell therapy focus, and which may reverse the age of cells already in the body through our iTR platform. We believe that our new technologies will lead to true cell regeneration and replacement to potentially cure degenerative diseases by targeting aged or damaged cells, tissues and organs.

Over the last year, we have worked hard to achieve certain goals to set the fundamental basis to create shareholder value going forward:

To optimize shareholder value, we have undertaken a strategic review of our business opportunities, and we have four key take-away messages for the coming year and beyond:

UniverCyte would potentially be game-changing for the whole cell therapy industry by allowing the transplantation of non-self, donor cells into all patients without the need for powerful immunosuppressant drugs, which are associated with serious side effects, including infections and cancers, as well as kidney and liver toxicity. The UniverCyte platform aims to utilize a proprietary, novel, modified form of the powerful immunomodulatory molecule HLA-G, which in nature seems to be a dominant player in protecting a baby from destruction by the mother's immune system during pregnancy, the only known physiological state of immune tolerance toward foreign tissue in humans.

On the other hand, our pluripotent stem cell-based PureStem platform could potentially overcome numerous industry barriers. PureStem cells would have eight potential advantages compared to other adult stem cell- or pluripotent stem cell-based therapies, including lower manufacturing costs, industrial scalability, off-the-shelf usage, high purity, non-tumorgenicity, young age (so they are not prone to the disadvantages associated with older cells), aptitude for permanent cell engraftment, and potential to manufacture any human cell type.

We have two in-house product candidates, both targeting highly prevalent diseases of old age, with a high unmet medical need, and which are for multi-billion-dollar markets. Our lead internal program going forward will be AgeX-BAT1, which is brown fat cells for the treatment of type II diabetes. The last year has seen significant investment in cell therapy product candidates for diabetes by investors and large biotech. Earlier this year, we published a paper, Clonal Derivation of White and Brown Adipocyte Progenitor Cell Lines from Human Pluripotent Stem Cells, in the peer-reviewed scientific journal Stem Cell Research & Therapy, which showed that our PureStem platform generated highly pure, identifiable and scalable brown adipose cells, expressing active adipokines. Our second internal program will be AgeX-VASC1, composed of vascular endothelial progenitor cells for tissue ischemia, such as peripheral vascular disease and potentially cardiac and CNS ischaemia. Once we have a UniverCyte-modified pluripotent stem cell cGMP master cell bank, we will re-derive universal versions of AgeX-BAT1 and AgeX-VASC1 and then work to establish proof-of-concept in animal models.

We care deeply about our mission and the needs of our stockholders. We appreciate your support and the dedication of our scientists and employees as we forge a new future for medicine. We invite you to join us for the Annual Meeting of Stockholders on Monday, December 30, 2019. For those of you who cannot attend in person, our corporate update from that meeting will be webcast for your convenience.

Sincerely,

Michael D. West, Ph.D.

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.

Details of the oral presentation follow:

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.

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.

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.
