A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multicenter Dose-Finding Study of MK-0822 in the Treatment of Involutional Osteoporosis
In Brief
A Phase 2 clinical trial evaluating Odanacatib, Vitamin D3, and 2 other interventions for Osteoporosis Postmenopausal. Completed, enrolled 287 participants.
Detailed Summary
The purpose of this study is to assess the dose-response on the percent change from baseline in lumbar spine bone mineral density (BMD) at lumbar vertebrae 1 to 4 (L1- L4) when odanacatib (MK-0822) 10 mg, 25 mg, 50 mg or placebo is orally administered once weekly for 52 weeks to Japanese involutional osteoporosis participants. The study will also assess safety and tolerability of odanacatib (10, 25, and 50 mg) in these participants. The study will enroll approximately 280 participants and randomly assign them to 3 different doses of odanacatib or placebo for 52 weeks, along with supplemental vitamin D3 and calcium carbonate. The primary efficacy hypothesis is that a dose-response relationship on the percent change from baseline in lumbar spine BMD (L1- L4) is seen when odanacatib 10, 25, 50 mg or placebo is orally administered once weekly for 52 weeks to involutional osteoporosis participants. The primary safety hypothesis is that odanacatib will be safe and well tolerated over 52 weeks to involutional osteoporosis participants.
