On April 14, 2022 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, reported progress and encouraging early data in its MGTA-117 Phase 1/2 targeted conditioning clinical trial and a prioritization of its operating plan to more narrowly focus its capital allocation on the MGTA-117 targeted conditioning program, the CD45-ADC (antibody-drug conjugate) IND-enabling activities and the MGTA-145 stem cell mobilization efforts in sickle cell disease (Press release, Magenta Therapeutics, APR 14, 2022, View Source [SID1234612226]).

The Company’s most significant near-term clinical milestone is its anticipated data from the MGTA-117 Phase 1/2 clinical trial in patients with relapsed/refractory acute myeloid leukemia and myelodysplasia-excess blasts. Multiple patients have been dosed in Cohort 1 of the ongoing clinical trial. Based on a preliminary review of the data from the trial to date, Magenta believes that the data suggest early signals of positive pharmacodynamic activity and that MGTA-117 has been well-tolerated, with no reports of unexpected or significant drug-related adverse events. Magenta looks forward to translating data from this clinical trial for use in transplant-eligible patients in the future. In its Q1 2022 earnings release scheduled for early May 2022, Magenta plans to disclose a summary of clinical observations from these initial patients with respect to CD117 target binding, drug clearance, cell depletion and tolerability.
Due to both its early positive experience with the MGTA-117 clinical trial and in response to the uncertain capital market environment for biotechnology companies, Magenta recognizes the need for an increased focus on MGTA-117 while also de-prioritizing other portfolio investments. The revised operating plan includes reductions in spending related to general and administrative expenses and research platform-related investments in new disease targets, as well as pausing certain MGTA-145 investments, including the program’s planned MGTA-145 dosing and administration optimization clinical trial in healthy subjects.
Magenta’s revised operating plan also reduces the Company’s workforce by 14% and allows Magenta to extend its cash runway into Q2 2024.
"We are encouraged by our progress in the MGTA-117 clinical trial and want to proactively address our resource allocation to ensure focus on creating value for patients and all of our stakeholders," said Jason Gardner, President and Chief Executive Officer of Magenta Therapeutics. "We have the utmost respect and appreciation for our departing employees and their contribution to advancing our programs."
