SOUTH SAN FRANCISCO, Calif., June 13, 2025 (GLOBE NEWSWIRE) -- Alector, Inc. (Nasdaq: ALEC), a late-stage clinical biotechnology company focused on developing therapies to counteract the devastating progression of neurodegeneration, today announced that its Chief Financial Officer (CFO), Marc Grasso, M.D., will conclude his tenure with the company, effective June 20, 2025, to pursue other opportunities. Neil Berkley, M.B.A., the company’s Chief Business Officer, will assume the role of Interim CFO while continuing in his current position.

“Marc has been a valuable member of our leadership team and a strong steward of the company since joining Alector in February 2022,” said Arnon Rosenthal, Ph.D., Chief Executive Officer of Alector. “He played a key role in strengthening our financial position and building a high-performing finance team. With cash runway into the second half of 2027, Alector is well positioned to advance our clinical, preclinical, and research programs through key inflection points. As Neil steps into the role of Interim CFO, the solid financial infrastructure established under Marc’s leadership, combined with Neil’s experience in corporate development and business strategy, will help ensure a smooth transition. We thank Marc for his significant contributions and wish him continued success in his next chapter, and we look forward to Neil’s expanding leadership role as Chief Business Officer and Interim CFO.”

Alector currently has two late-stage clinical candidates being developed in collaboration with GSK. The company remains on track to report topline data from the pivotal INFRONT-3 Phase 3 trial of latozinemab in frontotemporal dementia with a GRN gene mutation (FTD- GRN ) in Q4 2025 and completed enrollment in the PROGRESS-AD Phase 2 trial of AL101 in early Alzheimer’s disease (AD) in April 2025. Additionally, Alector continues to strategically pursue research and preclinical programs selectively supported by its proprietary blood-brain barrier technology platform, Alector Brain Carrier (ABC), including ADP037-ABC, its brain-penetrant anti-amyloid beta antibody for AD, and ADP050-ABC, its brain-penetrant GCase enzyme replacement therapy for Parkinson’s disease.

“It has been an honor to contribute to Alector’s mission of developing innovative therapies for neurodegenerative diseases,” said Dr. Grasso. “I’m proud of the financial position the team has established to support the company’s progress. I have full confidence in Neil and the entire leadership team to guide Alector through this next phase. I remain committed to ensuring a smooth transition and wish Alector continued success in advancing its important pipeline.”
