NCT00885170

Brief Summary

The study will evaluate the both the efficacy of odanacatib on Bone Mineral Density (BMD) and the safety of odanacatib for postmenopausal osteoporosis in patients previously treated with alendronate. The primary hypothesis of the trial is that treatment with odanacatib 50 mg once weekly will increase bone mineral density at the femoral neck compared to placebo at the end of 24 months.

Outcome Measures

Primary Outcomes (3)

  • Percent Change From Baseline in Femoral Neck Bone Mineral Density (BMD) at Month 24

    BMD at the femoral neck was assessed by dual-energy X-ray absorptiometry (DXA) at baseline and Month 24.

    Baseline and Month 24

  • Percentage of Participants Experiencing One or More Adverse Events (AEs)

    An AE was defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it was considered related to the medical treatment or procedure, that occurred during the course of the study.

    Up to 25 months

  • Percentage of Participants Discontinuing Study Drug Due to an AE

    An AE was defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it was considered related to the medical treatment or procedure, that occurred during the course of the study.

    Up to 24 months

Secondary Outcomes (22)

  • Percent Change From Baseline in Femoral Neck BMD at Month 12

    Baseline and 12 Months

  • Percent Change From Baseline in Trochanter BMD at Month 24

    Baseline and 24 Months

  • Percent Change From Baseline in Trochanter BMD at Month 12

    Baseline and 12 Months

  • Percent Change From Baseline in Total Hip BMD at Month 24

    Baseline and 24 Months
