Arms Assigned Interventions
Experimental: NBI-56418 150 mg q.d. Drug: NBI-56418
150 mg immediate release (IR) taken daily, 24 week duration
Placebo Comparator: Placebo Drug: Placebo
Matching placebo tablet taken daily, 8 week duration

Detailed Description:
This is a Phase 2, multicenter, randomized, double-blind, placebo controlled parallel group study to assess the efficacy and safety of 150 mg NBI-56418 administered once daily (q.d.) for up to 24 weeks. Approximately 120 subjects will be randomized (1:1) to 150 mg NBI-56418 q.d. or placebo q.d. for the first 8 weeks of dosing. Following 8 weeks of dosing, subjects will continue in the study for an additional 16 weeks in an open-label phase where all subjects still enrolled in the study will receive 150 mg q.d.
