Detailed Description:

This is a Phase II, multicenter, randomized, double-blind, placebo-controlled parallel-group study to assess the efficacy and safety of NBI-56418 at two dose levels administered once daily for up to 6 months. Approximately 150 subjects will be randomized (1:1:1) to one of the following treatment groups for the first 12 weeks of dosing: 150 mg NBI-56418 q.d.; 250 mg NBI-56418 q.d; or placebo q.d. Following 12 weeks of dosing, subjects will continue in the study for an additional 12 weeks; subjects randomized to NBI-56418 will continue to receive their assigned dose and subjects randomized to placebo will be re-randomized to receive one of the two doses of NBI-56418 for 12 weeks in a double-blind fashion. The effect of NBI-56418 treatment on bone mineral density (BMD) following 6 months of treatment with NBI-56418.
