Acumen Pharmaceuticals IncNew data shows ACU401 achieved up to 40-fold brain exposure in primates, a positive technology development for Acumen.
Acumen Pharmaceuticals announced new data at the Alzheimer's Association International Conference 2026 showing its Enhanced Brain Delivery candidate ACU401 achieved up to 40-fold greater frontal cortex exposure in non-human primates compared to a native anti-AβO antibody. The bispecific antibodies, developed with JCR Pharmaceuticals, target both amyloid beta oligomers and the transferrin receptor, and demonstrated improved brain penetration without hematological safety signals. The company also presented patient experience findings from the ALTITUDE-AD Phase 2 trial, highlighting unmet needs in early Alzheimer's disease. Acumen is advancing sabirnetug in the ongoing ALTITUDE-AD study, with topline results expected in late 2026.
