A Study to Examine the Effects of an Experimental Drug on Women With Breast Cancer and Metastatic Bone Disease (MBD)(0822-016)(COMPLETED)

Phase 2
Completed
Conditions
Breast Cancer
Metastatic Bone Disease
Interventions
Drug: ZA
Drug: ZA matching placebo
Registration Number
NCT00399802
Lead Sponsor
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.

Primary Outcome Measures
NameTimeMethod
Percentage Change From Baseline in Urinary N-telopeptide of Type I Collagen (u-NTx) at Week 4Baseline 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 AEUp 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
NameTimeMethod
Percentage Change From Baseline in Urinary Deoxypyridinoline (u-DPD) at Week 4Baseline 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.
