ACADIA's Pimavanserin Meets Primary and Key Secondary Endpoints in Pivotal Phase III Parkinson's Disease Psychosis Trial

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. These results were further supported by a highly significant improvement in the secondary efficacy measure, the Clinical Global Impression Improvement, or CGI-I, See full press release
