ACADIA Announces Pimavanserin Meets Primary and Key Secondary Endpoints in Pivotal Phase III Parkinson’s Disease Psychosis Trial
Pimavanserin Demonstrates Highly Significant Antipsychotic Efficacy and Maintenance of Motor Control in Parkinson’s Patients
Significant Improvements Also Observed in All Secondary and Exploratory Measures
ACADIA Pharmaceuticals Inc. (ACAD) today announced successful top-line results from its pivotal Phase III trial evaluating the efficacy, tolerability and safety of pimavanserin in patients with Parkinson’s disease psychosis (PDP). Pimavanserin is ACADIA’s proprietary, non-dopaminergic product candidate that selectively blocks serotonin 5-HT2A receptors. Pimavanserin met the primary endpoint in the Phase III trial by demonstrating highly significant antipsychotic efficacy as measured using the 9-item SAPS-PD scale (p=0.001). Pimavanserin also met the key secondary endpoint for motoric tolerability as measured using Parts II and III of the Unified Parkinson’s Disease Rating Scale, or UPDRS.
