CAMBRIDGE, Mass., Nov. 03, 2022 (GLOBE NEWSWIRE) — Magenta Therapeutics (Nasdaq: MGTA), a clinical-stage biotechnology company developing novel medicines designed to bring the curative power of stem cell transplant to more patients, today reported financial results for the third quarter ending September 30, 2022, and recent program highlights.
“We are building momentum in the MGTA-117 clinical trial with new clinical results and are making progress across our pipeline, including our second targeted conditioning program CD45-ADC,” said Jason Gardner, President and Chief Executive Officer of Magenta Therapeutics, Inc. “In the MGTA-117 Phase 1/2 clinical trial, we continue to enroll and generate clinical data in higher-dose cohorts. Our preclinical work has been particularly helpful in predicting our clinical experience in these early dose cohorts regarding MGTA-117 activity at different exposure levels and the overall tolerability profile. We look forward to presenting available clinical data at ASH and using our data to support interactions with regulators as we plan to advance MGTA-117 to stem cell transplant-eligible patients and into gene therapy.”
Program Highlights:
MGTA-117 Phase 1/2 Clinical Trial Progression and Data Disclosure Expectations
MGTA-117 is Magenta’s most advanced targeted conditioning product candidate designed to deplete target cells prior to a patient undergoing stem cell transplant or receiving an ex vivo gene therapy product. The program is currently enrolling patients with relapsed/refractory acute myeloid leukemia (AML), and myelodysplastic syndromes (MDS), in a Phase 1/2 dose escalation clinical trial. MGTA-117 is an anti-CD117 antibody conjugated to an amanitin payload. CD117, also known as c-Kit receptor, is highly expressed on hematopoietic stem cells, progenitor cells, and leukemic cells.
CD45-Antibody Drug Conjugate (ADC): Second Targeted Conditioning Program
Magenta’s CD45-ADC is designed to selectively target and deplete both stem cells and immune cells and is intended to replace the use of chemotherapy and radiation-based conditioning prior to stem cell transplant in patients with blood cancers and autoimmune diseases.
MGTA-145 Stem Cell Mobilization and Collection
Magenta is developing MGTA-145, in combination with plerixafor, to improve the process by which stem cells are released out of the bone marrow and into the bloodstream, known as stem cell mobilization. The mobilized cells are then collected and available for transplant. This is the first step for patients and is required for the majority of transplants and stem cell gene therapies.
Financial Results:
Cash Position: Cash, cash equivalents and marketable securities as of September 30, 2022, were $128.3 million, compared to $176.9 million as of December 31, 2021. The September cash balance includes gross proceeds of $3.0 million from our “at-the-market” facility. Magenta anticipates that its cash, cash equivalents and marketable securities will be sufficient to fund its current operational plan into Q2 2024.
Research and Development Expenses: Research and development expenses were $11.2 million in the third quarter of 2022, compared to $10.8 million in the third quarter of 2021. The increase was driven primarily by higher preclinical and manufacturing costs to support our IND-enabling studies for CD45-ADC, offset by a decrease in clinical trial costs related to our mobilization program.
General and Administrative Expenses: General and administrative expenses were $6.1 million for the third quarter of 2022, compared with $7.5 million in the third quarter of 2021. The decrease was primarily due to a decrease in stock-based compensation.
Net Loss: Net loss was $16.1 million for the third quarter of 2022, compared to net loss of $17.4 million for the third quarter of 2021.
