Acadia’s Alzheimer’s psychosis drug misses main goal of mid-stage study
Acadia Pharmaceuticals reported that its experimental drug for Alzheimer's psychosis, remlifanserin, missed the main goal of a mid-stage study. The 60-mg dose showed improvement over placebo but not enough to meet the primary endpoint. The 30-mg dose showed little benefit. Despite this, Acadia will continue late-stage studies, removing the 30-mg arm. The company expects peak sales of $4 billion. Analysts suggest a potential path forward.
