- Merck Sharp & Dohme LLC
- Brief Summary
This is a 4-week study to examine the effects of a new experimental medication on women with breast cancer and established bone metastases. This study will enroll approximately 45 women. The primary hypotheses are: (1) odanacatib will result in a substantial suppression of urinary N-telopeptide of type I collagen (u-NTx) similar to that achieved with an intravenous (IV) infusion of zoledronic acid (ZA) over 4 weeks of treatment; and (2) odanacatib (MK-0822) will be safe and well tolerated during 4 weeks of treatment.

Group Intervention Description Single IV infusion of ZA 4 mg Odanacatib matching placebo Participants will receive a single IV infusion of ZA 4 mg at the start of treatment and a once-daily odanacatib matching placebo tablet for 4 weeks. Single IV infusion of ZA 4 mg ZA Participants will receive a single IV infusion of ZA 4 mg at the start of treatment and a once-daily odanacatib matching placebo tablet for 4 weeks. Odanacatib 5 mg ZA matching placebo Participants will receive a once-daily odanacatib 5 mg tablet for 4 weeks and a single IV infusion of ZA matching placebo at the start of treatment. Odanacatib 5 mg Odanacatib Participants will receive a once-daily odanacatib 5 mg tablet for 4 weeks and a single IV infusion of ZA matching placebo at the start of treatment.
- Primary Outcome Measures
Name Time Method Percentage Change From Baseline in Urinary N-telopeptide of Type I Collagen (u-NTx) at Week 4 Baseline and Week 4 u-NTx is a biochemical index of bone resorption. Participants provided urine specimens on Day 1 (baseline) and at Week 4 for measurement of u-NTx.
Number of Participants Who Experienced an Adverse Event (AE) Up to 6 weeks 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.
Number of Participants Who Discontinued Treatment Due to an AE Up to 4 weeks 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
Name Time Method Percentage Change From Baseline in Urinary Deoxypyridinoline (u-DPD) at Week 4 Baseline and Week 4 u-DPD is a biochemical marker of bone resorption. Participants provided urine specimens on Day 1 (baseline) and Week 4 for measurement of u-DPD.
