Onconova Therapeutics Announces the Unexpected Passing of Chief Medical Officer Dr. Mark Gelder

By: via GlobeNewswire

NEWTOWN, Pa., April 06, 2023 (GLOBE NEWSWIRE) -- Onconova Therapeutics, Inc. (NASDAQ: ONTX), (“Onconova” or “the Company”), a clinical-stage biopharmaceutical company focused on discovering and developing novel products for patients with cancer, today announced that its Chief Medical Officer (CMO) Mark Gelder, M.D., recently passed away unexpectedly. Michael Saunders, M.D., has been appointed the interim Chief Medical Officer of the Company.

“The entire Onconova family is deeply saddened by the loss of our beloved friend and colleague,” said Steven M. Fruchtman, M.D., President and Chief Executive Officer of Onconova. “Dr. Gelder dedicated his career to caring for and improving the treatment options available to patients with cancer and his thought leadership and scientific passion will be sorely missed by the oncology community. Mark trained and worked as a gyn oncologist. Because of that experience, he was dedicated to advancing the care of women with reproductive tract cancers. Our goal is to complete the mission Mark started by advancing our trial in endometrial cancer and other cancers as well. We are immensely grateful for his many contributions to Onconova and express our deepest condolences to his family, friends, and colleagues during this difficult time. May he rest in peace.”

Dr. Gelder served as Onconova’s CMO since June 2021. He was an accomplished industry leader with more than 35 years of experience in clinical development, medical affairs, and medical marketing. His previously held the role of CMO at Elevar Therapeutics, Pierian Biosciences (formerly DiaTech Oncology), Accelovance, Inc., and Heron Therapeutics, Inc. Dr. Gelder also had extensive experience at large pharmaceutical companies including Pfizer, Wyeth, and Bayer. He earned his M.D. from the University of Virginia School of Medicine, completed a fellowship in gynecologic oncology, and was a Fellow of the American College of Physicians and the American College of Obstetrics and Gynecology.

Onconova’s Board of Directors will convene at an appropriate time to appoint a new CMO. A search is currently underway by the Company. Onconova does not expect any material impact to the stated timelines associated with its ongoing or planned clinical trials due to this sad news. The Company notes that Dr. Michael Saunders, a noted drug developer and colleague, has been working with Onconova as a consultant and is thus well acquainted with the Company’s compounds in development.
