NEWARK, Calif., May 30, 2023 (GLOBE NEWSWIRE) -- Rain Oncology Inc. (NasdaqGS: RAIN), (Rain), a clinical stage company developing precision oncology therapeutics today announced an update to its clinical strategy for milademetan, its small molecule inhibitor of the MDM2-p53 complex, to optimize Company resources. The Company is focused on reducing its cash burn with the expectation to extend cash runway to year-end 2026.
“We are working diligently, as additional information continues to come in, to analyze and understand the outcomes in the Phase 3 MANTRA study in DD LPS,” said Avanish Vellanki, co-founder and chief executive officer of Rain. “It is imperative we understand those outcomes before allocating further capital to the milademetan program, with corporate expenses to be greatly reduced to maximize optionality for Rain. In the near-term, Rain plans to suspend enrollment in our Phase 2 MANTRA-2 basket trial and terminate plans to initiate the planned Phase 1/2 MANTRA-4 combination trial.”
Mr. Vellanki continued, “Rain will make meaningful reductions in our workforce. It was the tremendous effort of our Rain colleagues that allowed us to execute on MANTRA ahead of schedule despite the extreme pressures of the pandemic. I want to sincerely thank every Rain colleague who has been impacted by this realignment. Their contributions have, without a doubt, brought us closer to better understanding the milademetan program, and towards Rain achieving its mission for patients.”
The Company thanks Dr. Richard Bryce, MBCHB, MRCGP, MFPM, Rain’s CMO, for his tremendous efforts with the MANTRA study, and notes a planned transition from CMO to an ongoing advisory role, with Rain’s cofounder, President and chief scientific officer, Dr. Robert Doebele, MD, PhD, to assume the role of CMO.

Rain has recently announced topline data of its Phase 3 trial of milademetan (MANTRA) in patients with LPS. Milademetan has received Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) for the treatment of LPS.
