Primary outcomePrimary: Unified Parkinson's Disease Rating Scale (UPDRS) Part III — -9.83; -5.91 units on a scale
Summary
This randomized, multicenter, placebo-controlled, double-blind study will evaluate the efficacy and safety of inhaled CVT 301 compared with placebo in PD patients experiencing motor response fluctuations (OFF phenomena) as an outpatient (i.e., at home) and in the clinic.
Patients who successfully complete this study will be eligible to enroll into a 12 month treatment extension (CVT-301-004E) study.
