ACADIA initiates new pimavanserin Phase III trial for Parkinson's disease psychosis

ACADIA Pharmaceuticals Inc. (Nasdaq: ACAD), a biopharmaceutical company utilizing innovative technology to fuel drug discovery and clinical development of novel treatments for central nervous system disorders, today announced that it has initiated a new Phase III trial designed to evaluate the efficacy, tolerability and safety of pimavanserin as a treatment for patients with Parkinson's disease psychosis (PDP).

“We believe pimavanserin has an ideal profile to effectively treat PDP without impairing motor function and, therefore, provides the potential for an important advance in therapy for patients suffering from this large unmet medical need.”

"This Phase III trial builds on the signals of efficacy observed in our earlier PDP studies and uses a refined study design that we expect will help mitigate the placebo response, reduce variability and enhance sensitivity in measuring the efficacy of pimavanserin in PDP patients," said Uli Hacksell, Ph.D., Chief Executive Officer of ACADIA Pharmaceuticals. "We believe pimavanserin has an ideal profile to effectively treat PDP without impairing motor function and, therefore, provides the potential for an important advance in therapy for patients suffering from this large unmet medical need."
