NEW HAVEN, Conn., July 09, 2025 (GLOBE NEWSWIRE) -- Arvinas, Inc. (NASDAQ:ARVN), a clinical-stage biotechnology company working to develop a new class of drugs based on targeted protein degradation, today announced that John Houston, Ph.D., Chairperson, Chief Executive Officer (CEO) and President at Arvinas, has informed the Board of Directors of his plans to retire from his role as President and CEO following a search for, and the appointment of, the Company's new CEO. The Arvinas Board of Directors has begun a search for a new CEO, and Dr. Houston will remain Chairperson of Arvinas' Board of Directors upon retiring as President and CEO.

"On behalf of the Arvinas Board of Directors, I sincerely thank John for his exceptional leadership and significant contributions to Arvinas over the past 8 years and his commitment to a smooth transition as we identify his successor," said Briggs Morrison, M.D., Arvinas Board Member and Lead Independent Director. "John has guided Arvinas through a substantial number of ‘firsts' for PROTACs in the industry, from the first to enter the clinic to the first positive pivotal Phase 3 trial and the first new drug application. John and Arvinas have turned targeted protein degradation into a well-known modality across several therapeutic areas. Due to his efforts, the Company is well positioned to benefit many patients in the years to come. As we undertake the process of identifying a new CEO, the Board is committed to conducting a thoughtful search to ensure continued strong leadership. We look forward to continuing our work with John in his capacity as Chairperson."

With more than 35 years of experience in the pharmaceutical and biotech industries, Dr. Houston joined Arvinas in January 2017 as President of Research and Development and Chief Scientific Officer responsible for leading the discovery, translational, and early clinical development research efforts. In September 2017, Dr. Houston was appointed President and CEO, and in 2023 he was named Arvinas' Chairperson.

During his tenure as CEO, Dr. Houston has been instrumental in Arvinas' success moving six programs into the clinic, reporting the results of the first positive pivotal Phase 3 trial for a PROTAC, and reporting for the first time that an orally administered PROTAC can achieve pharmacodynamic activity in the central nervous system.

"It has been an honor to lead Arvinas alongside incredibly talented colleagues and a supportive Board of Directors," said Dr. Houston. "I look forward to remaining a part of Arvinas as Chairperson and I'm confident in the Company's ability to improve the lives of patients with serious diseases through our revolutionary PROTAC protein degradation platform. From initiating the first oral PROTAC degrader in clinical trials to delivering positive topline results, it is evident that Arvinas has and will continue to push the boundaries of what's possible."
