Geron Corporation Announces Appointment of Faye Feller, M.D. to Chief Medical Officer and Transition of Aleksandra Rizo, M.D., Ph.D. to Senior Advisor Role

FOSTER CITY, Calif.–(BUSINESS WIRE)–Geron Corporation (Nasdaq: GERN), a late-stage clinical biopharmaceutical company, today announced the appointment of Faye Feller, M.D., to Executive Vice President and Chief Medical Officer, effective July 9, 2022. Dr. Feller will succeed Dr. Aleksandra Rizo, Geronʻs current Chief Medical Officer, who will transition to a consultant role to the Company, as Senior Medical and Regulatory Advisor. Outside of Geron, Dr. Rizo has accepted a leadership position with a privately held discovery and preclinical-stage platform biotechnology company.

Dr. Feller has been instrumental in the design, execution and management of the imetelstat development program for the past seven years, starting when she served as a medical leader in Janssen’s hematology program. She has continued her work on imetelstat since 2019, as Geronʻs Vice President of Clinical Development reporting to Dr. Rizo.

“Faye has been a cornerstone in the history of imetelstat’s clinical development. Since coming to Geron, she has played a strategic role in designing and driving execution of our Phase 3 clinical trials. In addition, she serves as the primary medical point of contact between Geron and our clinical investigators, leads the preparation of data for assessment by the data monitoring committees, and is preparing for the top-line readout of our IMerge Phase 3 trial in lower risk myelodysplastic syndromes, which is expected in early January 2023,” said John A. Scarlett, M.D., Chairman and Chief Executive Officer. “With her background as clinical lead for multiple clinical trials while at Janssen, and as an attending hematologist at Memorial Sloan Kettering Cancer Center, Faye is highly qualified to assume her new role as our Chief Medical Officer.”

When Dr. Feller becomes Chief Medical Officer, Dr. Rizo will transition to the consultant role, where she will continue to be involved in key imetelstat development and regulatory activities. These include assessment of data for top-line results from the ongoing IMerge Phase 3 trial in lower risk myelodysplastic syndromes (MDS) and, assuming supportive top-line results, through the planned FDA New Drug Application submission and acceptance process for imetelstat in lower risk MDS.

“Aleksandra has made tremendous contributions to the development of imetelstat,” Dr. Scarlett continued. “Her leadership in building and mentoring a deep and experienced development organization is evident with the internal promotion of Faye as Chief Medical Officer. We appreciate the continuity in involvement Aleksandra will provide as Faye assumes her new responsibilities.”

“It has been a privilege to work with Chip and the Geron team to advance this innovative first-in-class telomerase inhibitor, imetelstat, into the late stages of clinical development. I remain confident in the potential of imetelstat to be a transformative treatment for patients with hematologic malignancies, and as such, I am fully committed to continuing to contribute to the imetelstat journey through the potential New Drug Application submission and acceptance process. In particular, I am eager to see the Phase 3 top-line results from the lower risk MDS trial expected in early January 2023,” Dr. Rizo said. “I am also completely confident that imetelstat will be in excellent hands with Faye and the rest our team at Geron, many of whom I have worked with side-by-side on imetelstat over the past seven years, and for whom I have the greatest respect.”

Prior to joining Geron, Dr. Feller was Senior Director at Janssen Research and Development, LLC (Janssen) and both a Compound Lead and Study Responsible Physician for multiple clinical trials of early and late-stage development assets at Janssen, including the IMbark Phase 2 clinical trial of imetelstat. Prior to Janssen, Dr. Feller was an attending physician in the leukemia department of Memorial Sloan Kettering Cancer Center in New York. She received a B.A. from New York University and an M.D. from Mount Sinai School of Medicine. She completed her residency in internal medicine at Mount Sinai Hospital and her fellowship in medical oncology at Memorial Sloan Kettering Cancer Center.
