(Nasdaq: ACAD) today announced publication of open-label extension (OLE) data from patients experiencing hallucinations and delusions associated with Parkinson’s disease psychosis (PDP) who had previously completed one of three, six-week, double-blind, placebo-controlled studies.\n\nThe OLE efficacy analysis showed that patients previously on NUPLAZID 34 mg had a sustained efficacy response from Week 6 through Week 10, and that patients who had been treated with investigational doses of 8.5 mg and 17 mg or placebo also showed an improvement in the symptoms of psychosis when switched to NUPLAZID 34 mg over the 4 weeks of the OLE. The completed study was published online and in the June issue of Parkinsonism and Related Disorders.
