What researchers measure

Primary outcomes

  1. Safety will be evaluated based on incidence of adverse events (AEs) and significant changes in physical examinations, vital signs, ECGs, and routine clinical laboratory assessments from baseline to the end of each treatment period (28 days).

    Time frame: 28 days

  2. Extrapyramidal signs are assessed with the motor subsection of the Unified Parkinson's Disease Rating Scale (UPDRS, Parts II and III).

    Time frame: 28 days

Secondary outcomes

  1. Change in the frequency and severity of visual hallucinations from baseline to the end of each treatment period (28 days) with Nelotanserin or placebo, as recorded and documented by the patient's caregiver

    Time frame: 28 days
