Acumen Pharmaceuticals announced results at the Alzheimer's Association International Conference (AAIC) 2025, demonstrating that its blood-based pTau217 screening assay reduced overall clinical trial screening costs by approximately 40% in the Phase 2 ALTITUDE-AD study. This efficiency streamlines patient identification for the trial.
The company also presented a nonclinical study evaluating the relative selectivity of sabirnetug for targeting AβOs versus Aβ monomers. This research reinforces sabirnetug's distinct selectivity for toxic amyloid beta oligomers, which is central to its differentiated mechanism of action.
These presentations highlight how combining biomarker-driven screening with a targeted therapeutic represents meaningful progress in trial designs and drug development for Alzheimer’s disease. The findings support both the operational efficiency of the trial and the scientific rationale behind sabirnetug.
