Rick Fair, a seasoned executive with deep experience developing and commercializing hematology products, joins Enliven as Chief Executive Officer

Co-Founder Sam Kintz will assume a new position as Head of Pipeline

BOULDER, Colo., Dec. 11, 2025 /PRNewswire/ -- Enliven Therapeutics, Inc. (Enliven or the Company) (NASDAQ:ELVN), a clinical-stage biopharmaceutical company focused on the discovery and development of small molecule therapeutics, today announced the appointment of Rick Fair as Chief Executive Officer and member of the Board of Directors of Enliven, effective December 11, 2025. Sam Kintz, Co-Founder and former Chief Executive Officer of Enliven, will assume a new role as Head of Pipeline, also effective December 11, 2025. The transition plan reflects Enliven's commitment to the next phase of the Company, including a pivotal Phase 3 trial for ELVN-001 in patients with chronic myeloid leukemia (CML) and its commercialization. Additionally, this transition enables a dedicated focus to develop and potentially advance Enliven's existing early pipeline assets to the clinic.

"I am pleased to announce the appointment of Rick Fair as Enliven's new CEO. Rick has substantial experience bringing late-stage oncology and hematology assets to commercialization. He joins us at a critical time as we plan to initiate a pivotal Phase 3 clinical trial of ELVN-001 in 2026. His expertise adds to Enliven's ability to design and execute a successful Phase 3 trial and commercialize ELVN-001 to deliver long-term value to our stockholders," said Richard Heyman, Ph.D., Chairman of the Board of Directors.

Mr. Fair has more than 25 years of experience in product development and commercialization, including 20 years with large pharmaceutical companies. He most recently served as President and Chief Executive Officer of Bellicum Pharmaceuticals, a clinical-stage biopharmaceutical company researching novel, controllable cellular immunotherapies for cancers. Prior to leading Bellicum, Mr. Fair served over 10 years with Roche/Genentech in commercial leadership positions of increasing responsibility. Over his last four years at Roche/Genentech, he led the Global Product Strategy Oncology/Hematology group responsible for developing and implementing lifecycle plans for its late-stage and in-market portfolio. During this time, he oversaw the launch of five new therapies and numerous new indications across solid and hematologic tumors, and the commercialization plans for a $23 billion business. Prior to Roche/Genentech, Mr. Fair spent nearly 10 years with Johnson & Johnson where he served in leadership positions in market access and marketing. He holds a B.S. from the University of Michigan and an M.B.A. from Columbia Business School.

"I am very excited to join Enliven as CEO at this important phase and look forward to working with this team to bring ELVN-001 through its Phase 3 trial and to market," said Mr. Fair. "The data generated to date demonstrate that ELVN-001 has the potential to be the best-in-class ATP-competitive inhibitor for the treatment of CML and provide patients with CML a treatment with better efficacy, tolerability and convenience than currently approved therapies."

Dr. Heyman added, "We are extremely grateful to Sam for his significant contributions to Enliven and look forward to his continued work leading our early-stage research programs. As a co-founder and CEO of Enliven, Sam has been instrumental in the early development of ELVN-001 and advancing the program into clinical trials. The Board is excited that Sam will remain engaged with Enliven to lead our existing early pipeline initiatives. Thanks to Sam and the team, we remain well positioned clinically and financially to execute on our next phase of growth."

"We welcome Rick and his deep product development and commercialization experience during this incredibly exciting time," said Mr. Kintz. "I am proud of the team's achievements to date and remain committed to the long-term success of Enliven and ELVN-001. I am also excited to return to my roots to lead our early pipeline efforts. I started my career as a medicinal chemist, and I am most passionate about the discovery through proof-of-concept stage of drug development. We have ongoing efforts that I believe could further transform Enliven and provide long-term value to our stockholders. I truly believe these leadership changes are best for Enliven's future. It has been a pleasure serving as Enliven's CEO, and I am confident that Rick is the right person to lead us through our next chapter."
