FDA Panel Backs Acadia Parkinson’s Psychosis Drug
FDA’s Psychopharmacologic Drugs Advisory Committee has voted 12 to 2 to support approval of an Acadia Pharmaceuticals NDA for Nuplazid (pimavanserin) and its use in treating psychosis associated with Parkinson’s Disease (PDP). Agency reviewers had noted that data submitted showed that pimavanserin 40 mg was more efficacious than placebo for an acute treatment of PDP. The user fee action date for review completion is 5/1.
Panel members urged FDA to require a post-market safety study if the drug is approved because of the small number of patients studied. Some also said any agency-approved labeling should discourage any off-label use as a general antipsychotic.
