Acumen Pharmaceuticals (NASDAQ: ABOS) is a clinical-stage biopharmaceutical company developing a single product candidate, sabirnetug, targeting amyloid-beta oligomers (AßOs) for the treatment of Alzheimer's disease. The company generates no revenue from product sales and has not commercialized any products as of its FY2025 10-K filed March 26, 2026.

Incorporated in 1996, the company acquired exclusive rights to sabirnetug from Merck & Co. in 2011 and did not recommence meaningful operations until 2018. Daniel O'Connell serves as Chief Executive Officer. Sabirnetug has completed a Phase 1 trial (INTERCEPT-AD), which demonstrated near-maximal target engagement of AßOs at doses of 25 mg/kg Q2W and 60 mg/kg Q4W. All research and development activities rely on third-party CROs and CMOs, with no separately tracked program expenses given the single-asset pipeline.
