What the filing says
Acumen held an investor day presenting ALTITUDE-AD, a 542-participant Phase 2 study of sabirnetug (ACU193) with topline results expected late 2026. The study uses iADRS as primary endpoint and CDR-SB as key secondary, with safety readouts including ARIA rates. Additionally, Acumen advanced its Enhanced Brain Delivery (EBD) program with lead candidates ACU301 and ACU401 showing 35-40x higher brain exposure than monoclonal antibody in primate studies, targeting IND filing mid-2027.
