Blinded SAPS-PD Assessment After 10 Weeks of Pimavanserin Treatment for Parkinson’s Disease Psychosis

Abstract

Improvements at OLE Week 4 from pretreatment baseline were similar with placebo and pimavanserin in the Core Study. The beneficial effects observed with pimavanserin in the 6-week Core Study were maintained for 4 weeks in the blinded OLE, supporting the durability of response with pimavanserin 34 mg for PDP over 10 weeks.
