Magenta Therapeutics (Nasdaq: MGTA), a clinical-stage biotechnology company developing novel medicines to bring the curative power of stem cell transplants to more patients, today reported financial results for the fourth quarter and full-year ended December 31, 2020 and recent program highlights.
“Building on our momentum from 2020, we continue to advance our portfolio with now two active Phase 2 clinical trials evaluating MGTA-145 plus plerixafor in patients with blood cancers undergoing autologous and allogeneic stem cell transplant and an additional planned Phase 2 clinical trial evaluating stem cell mobilization and collection in patients with sickle cell disease in partnership with bluebird bio. We have also made additional progress in our preparations for an IND filing for our MGTA-117 targeted conditioning program based on communications with the FDA and the advancement of our IND-enabling studies,” said Jason Gardner, D.Phil., President and Chief Executive Officer, Magenta Therapeutics. “We very much look forward to generating clinical data during the course of 2021 in these multiple disease settings.”
Program Highlights:
MGTA-145: Stem Cell Mobilization and Collection for Hematopoietic Stem Cell Transplantation and Gene Therapy –
Magenta is developing MGTA-145 plus plerixafor to harness these agents’ complementary mechanisms to mobilize hematopoietic stem cells (HSCs) for collection and transplantation, including for use with gene therapies. The ability to provide rapid, reliable, predictable and safe mobilization and collection of HSCs in stem cell transplantation and gene therapy could position MGTA-145 plus plerixafor to be the preferred mobilization regimen across multiple diseases due to improved patient experience and collection outcomes.
MGTA-145 Current and Planned Activity:
-
Two active MGTA-145 Phase 2 clinical trials; One additional planned Phase 2 clinical trial:
- Autologous stem cell transplant in patients with Multiple Myeloma. Magenta announced in December 2020 that enrollment had commenced and is ongoing in an investigator-initiated Phase 2 clinical trial of Multiple Myeloma patients at Stanford University. The clinical trial is evaluating the ability of MGTA-145, in combination with plerixafor, to mobilize stem cells for collection prior to autologous stem cell transplant in Multiple Myeloma patients. Initial mobilization, collection and engraftment data from this trial are expected in mid-2021.
- Allogeneic donor stem cell mobilization and collection for stem cell transplant in patients with Acute Myeloid Leukemia (AML), Acute Lymphocytic Lymphoma (ALL) and Myelodysplastic Syndromes (MDS). Through a collaboration with the National Marrow Donor Program®/Be The Match®, Magenta has initiated a Phase 2 clinical trial evaluating MGTA-145, in combination with plerixafor, in the mobilization and collection of stem cells from allogeneic donors for transplant in patients with AML, ALL and MDS. Initial data from this trial are expected in the second half of 2021.
- Stem cell mobilization and collection in patients with Sickle Cell Disease. As announced in December 2020, Magenta and bluebird bio, Inc. entered into a Phase 2 clinical trial collaboration to evaluate the utility of MGTA-145, in combination with plerixafor, for the mobilization and collection of stem cells in patients with Sickle Cell Disease. Under the agreement, the companies will co-fund the clinical trial, which is currently expected to initiate in the second half of 2021.
MGTA-145 Recent and Upcoming Scientific Conference Presentations:
-
Magenta presented clinical data from its Phase 1 trial of MGTA-145 at the American Society of Hematology (ASH) Annual Meeting and Exposition, held December 5-8, 2020.
- The results provided proof-of-concept, demonstrating that all safety and efficacy endpoints were met and that mobilized stem cells showed functional superiority over stem cells collected from other mobilization approaches in preclinical studies. A single dose of MGTA-145, in combination with plerixafor, rapidly and reliably mobilized high numbers of stem cells in a single day without the need for G-CSF, demonstrating potential use in diseases that can benefit from autologous and/or allogeneic stem cell transplantation.
-
Magenta presented two oral presentations on MGTA-145 at the Transplantation and Cellular Therapy (TCT) Annual Meeting, held February 8-12, 2021.
- Data from the Phase 1 clinical trial with healthy volunteers underscored the potential utility of MGTA-145 plus plerixafor as an effective, single-day mobilization and collection regimen for autologous and allogeneic HSC transplant. The data show mobilization of high numbers of HSCs, durable engraftment, efficient gene modification and potent immunosuppressive properties by reducing Graft-versus-Host disease (GvHD) in preclinical models.
- Data from a separate preclinical study demonstrated the potential of MGTA-145 plus plerixafor to serve as an efficient, single-dose mobilization regimen for in vivo HSC gene therapy where stem cells could be gene corrected or edited without having to remove them from the body.
- Magenta will present data from the MGTA-145 program at the upcoming European Society for Blood and Marrow Transplantation (EBMT) annual meeting, to be held March 14-17, 2021.
MGTA-117: Targeted Conditioning –
Magenta is developing a platform of novel antibody-drug conjugates (ADCs) for conditioning, a step in the transplant process that currently relies on the use of systemic chemotherapy agents and radiation. Magenta’s targeted conditioning programs are designed to selectively eliminate stem cells and/or immune cells from a patient prior to transplant or gene therapy, and to reduce or potentially eliminate the need for high dose or high intensity chemotherapy-based regimens.
MGTA-117, Magenta’s most advanced conditioning program, is a CD117-targeted antibody conjugated to amanitin and intended for use in patients undergoing transplant. MGTA-117 is designed to deplete hematopoietic stem and progenitor cells to clear space in the bone marrow prior to transplant in support of long-term engraftment and improved disease outcomes in patients. MGTA-117 has shown high selectivity, potent efficacy and tolerability in multiple preclinical studies.
Targeted Conditioning Current and Planned Activity:
- MGTA-117 IND Filing Anticipated Mid-2021. Magenta recently completed its GLP toxicology studies, its GMP manufacturing process and has finished its pre-Investigational New Drug (IND) communications with the FDA and expects to file an IND application in mid-2021. Upon acceptance of the IND by the FDA, Magenta plans to initiate a Phase 1/2 clinical trial evaluating MGTA-117 in patients with AML and MDS to generate initial safety and pharmacokinetic data in the fourth quarter of 2021. These initial data are expected to be directional for the Company’s dose escalation plans.
- Magenta continues to evaluate CD45-ADC preclinically in various transplant and autoimmune disease models.
Targeted Conditioning Recent and Upcoming Scientific Conference Presentations:
-
Magenta provided updates on its MGTA-117 and CD45-ADC conditioning programs at the ASH Annual Meeting:
- In preclinical animal models of human AML, MGTA-117 decreased tumor burden leading to increased median survival rates versus a multi-day standard-of-care regimen.
- Preclinical data from a study of Magenta’s CD45-ADC conditioning program demonstrated the potential to achieve successful disease outcomes as a single agent in a fully mismatched allogeneic HSC transplant preclinical disease model.
-
Magenta gave an oral presentation of MGTA-117 and presented a poster of CD45-ADC at the TCT Annual Meeting:
- MGTA-117 was studied in multiple human leukemic xenograft preclinical models to mimic untreated and refractory AML. In preclinical models, MGTA-117 increased median survival versus a multi-day standard-of-care regimen using cytarabine.
- Preclinical data demonstrated that conditioning with single agent CD45-ADC enabled complete chimerism in a full mismatch allogeneic HSC transplant model. Developing a broad targeting approach for safer patient conditioning prior to HSC transplant could bring the curative potential of allogeneic HSC transplant to more patients with both malignant and non-malignant disorders. Current conditioning regimens limit accessibility of this procedure due to toxicity.
- Magenta will also present data on its MGTA-117 conditioning program at the upcoming European Society for Blood and Marrow Transplantation (EBMT) annual meeting, to be held March 14-17, 2021.
