Thompson, Ph.D., Head of Research and Development, Following a Distinguished Career<\/span><\/b><\/p>\n<p>SAN DIEGO&#8211;(<a href=\"http:\/\/www.businesswire.com\">BUSINESS WIRE<\/a>)&#8211;<br \/>\nAcadia Pharmaceuticals Inc. (Nasdaq: ACAD) today announced the planned retirement of Elizabeth H.Z. Thompson, Ph.D., Head of Research and Development. Dr. Thompson has decided to retire for personal reasons and informed Acadia of her plans. She will continue in her role as Head of Research and Development until a successor is appointed. After her retirement, Acadia plans to retain Dr. Thompson as a consultant through at least the end of 2026 to ensure scientific and leadership continuity through the planned readout of the Phase 2 clinical study of remlifanserin in Alzheimer\u2019s disease psychosis (ADP) and into early Phase 3 clinical study execution.<\/p>\n<p>\nAcadia has initiated a search for a new Head of Research and Development and is committed to identifying an experienced R&amp;D leader who will build on the strong scientific foundation already in place. The Company continues to advance its clinical development programs as planned. All ongoing clinical trials, including the Phase 2 studies of remlifanserin in ADP and Lewy Body Dementia Psychosis (LBDP), continue to recruit and remain blinded, and the Company, including Dr. Thompson, does not yet know study outcomes.<\/p>\n<p>\n\u201cLiz\u2019s leadership has been instrumental in strengthening Acadia\u2019s research and development organization, both scientifically and operationally, and in advancing a clear, disciplined R&amp;D strategy across our pipeline,\u201d said Catherine Owen Adams, Chief Executive Officer of Acadia. \u201cShe has been a strong advocate for the patients we serve and at every step has ensured thoughtful execution and prioritization of our programs in neurological and rare diseases. Just as importantly, Liz fostered a culture of clarity, accountability, and engagement across R&amp;D. We are grateful for her continued commitment to Acadia during the transition period and for her willingness to remain engaged as a consultant, providing continuity of scientific leadership and institutional perspective in support of our mission and, most importantly, the patients we serve.\u201d<\/p>\n<p>\n\u201cLeading Acadia\u2019s research and development organization has been a defining chapter in my career and one in which I take a great deal of pride,\u201d said Dr. Thompson. \u201cWe started from a great foundation, and have been able to build and strengthen the Acadia R&amp;D team as well as make good progress in shaping and advancing a curated pipeline. I am particularly pleased with how we\u2019ve been able to strengthen the remlifanserin program, especially by expanding it into Lewy Body Dementia Psychosis. I remain excited by the potential for remlifanserin and confident in the disciplined development strategy the Acadia team is executing. Beyond remlifanserin, our pipeline contains multiple programs that could represent truly meaningful options for patients living with neurological and rare diseases. While I have decided to retire for personal reasons, I am committed to continuing to lead the organization until the appointment of a successor and to supporting Acadia through the transition and the remainder of the year.\u201d<\/p>\n<p>\nDr. Thompson joined Acadia in 2024 serving as Head of Research and Development. During her tenure, she helped strengthen the Company\u2019s scientific and clinical capabilities, advance multiple development programs, and foster a culture of collaboration across research, clinical development and regulatory teams.<\/p>\n<p>\nAbout Acadia Pharmaceuticals<\/p>\n<p>\nAcadia is committed to turning scientific promise into meaningful innovation that makes the difference for underserved neurological and rare disease communities around the world. Our commercial portfolio includes the first and only FDA-approved treatments for Parkinson\u2019s disease psychosis and Rett syndrome. We are developing the next wave of therapeutic advancements with a robust and diverse pipeline that includes mid- to late-stage programs in Alzheimer\u2019s disease psychosis and Lewy body dementia psychosis, along with earlier-stage programs that address other underserved patient needs. At Acadia, we\u2019re here to be their difference.
