FDA Tells Acadia that Nuplazid sNDA has Deficiencies

Share

FDA has told Acadia Pharmaceuticals that its ongoing review of a supplemental NDA for Nuplazid (pimavanserin), indicated for treating hallucinations and delusions associated with dementia-related psychosis, has found deficiencies that preclude labeling and post-marketing requirements/commitments discussions at this time. The agency stated that its communication about the deficiencies does not reflect a final decision on the information under review, Acadia says.

 

FDA accepted the supplemental NDA for review 7/2020 and assigned a standard review with a user fee review action date of 4/2/2021. Acadia said at the time that the submission was based on data from the pivotal Phase 3 HARMONY study, which met its primary endpoint — demonstrating that pimavanserin significantly reduced the risk of relapse of psychosis by 2.8 fold compared to placebo. It also included a large safety database from completed and ongoing studies representing over 1,500 patients with neurodegenerative disease. Nuplazid was approved in 2016 for hallucinations and delusions associated with Parkinson’s disease psychosis.
