Primary Outcome Measures:
  • Long-term safety and tolerability will be evaluated based on incidence of adverse events (AEs) and significant changes in physical examinations, vital signs, ECGs, and clinical laboratory assessments over time during treatment. [ Time Frame: 24 weeks ]
  • Long-term effectiveness will be evaluated based on change in the frequency and severity of visual hallucinations (as recorded by patient's caregiver) and/or REM sleep behaviors (based on a clinical evaluator) over time during treatment. [ Time Frame: 24 weeks ]

Estimated Enrollment: 80
