Study Details

Study Description

Brief Summary

The purpose of this study is to test the hypothesis that treatment with odanacatib will result in increased bone mineral density (BMD) compared to treatment with placebo. This study will also evaluate the safety and efficacy of odanacatib for male osteoporosis participants.

Condition or Disease Intervention/Treatment Phase
  • Drug: Odanacatib
  • Drug: Placebo for Odanacatib
  • Dietary Supplement: Vitamin D3
  • Dietary Supplement: Calcium carbonate
Phase 3

Detailed Description

The original study was divided into two parts, with the primary analysis of endpoints to occur at 24 months and participants will then remain in the study for an additional 12 months (Part 2). Amendment 1 of the protocol removed the additional 12 month period and the Month 36 BMD analysis was deleted.

    Outcome Measures

    Primary Outcome Measures

    1. Percentage Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) at Month 24 [Baseline and Month 24]

      Lumbar spine BMD was assessed by dual energy X-ray absorptiometry (DXA) at Baseline and at Month 24.

    2. Number of Participants Who Experienced an Adverse Event (AE) [Up to 24 months (plus 14 days) after first dose of study drug]

      An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug, whether or not it is considered related to the study drug.

    3. Number of Participants Who Discontinued Treatment Due to an AE [Up to 24 months after first dose of study drug]

      An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug, whether or not it is considered related to the study drug.

    Secondary Outcome Measures

    1. Percentage Change From Baseline in Total Hip BMD at Month 24 [Baseline and Month 24]

      Total hip BMD was assessed by DXA at Baseline and at Month 24.

      Serum samples were collected to evaluate biochemical markers for s-BSAP, which were measured at Baseline and at Month 24.

    7. Percentage Change From Baseline in Serum N-Terminal Propeptides of Type I Collagen (s-P1NP) at Month 24 [Baseline and Month 24]
