Criteria

Inclusion Criteria:

A clinical diagnosis of Parkinson's disease with a minimum duration of 1 year
Presence of visual and/or auditory hallucinations, and/or delusions, occurring during the four weeks prior to study screening
Psychotic symptoms must have developed after Parkinson's disease diagnosis was established
Subject must be on stable dose of anti-Parkinson's medication for 1 month prior to Study Day 1 (Baseline) and during the trial
Subject that has received stereotaxic surgery for subthalamic nucleus deep brain stimulation must be at least 6 months post surgery and the stimulator settings must have been stable for at least 1 month prior to Study Day 1 (Baseline) and must remain stable during the trial
The subject is willing and able to provide consent
Caregiver is willing and able to accompany the subject to all visits

Exclusion Criteria:

Subject has a history of significant psychotic disorders prior to or concomitantly with the diagnosis of Parkinson's disease including, but not limited to, schizophrenia or bipolar disorder
Subject has received previous ablative stereotaxic surgery (i.e., pallidotomy and thalamotomy) to treat Parkinson's disease
Subject has current evidence of a serious and or unstable cardiovascular, respiratory, gastrointestinal, renal, mematologic or other medical disorder
Subject has had a myocardial infarction in last six months
Subject has any surgery planned during the screening, treatment or follow-up periods

Patients will be evaluated at screening to ensure that all criteria for study participation are met.
