Study on Prolonging Bone Metastasis-Free Survival in Men With Hormone Refractory Prostate Cancer

NCT ID: NCT00286091

Last Updated: 2018-10-17

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 1435 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2006-01-24
• Study Completion Date: 2014-04-09

Brief Summary

The purpose of this study is to compare the treatment effect of denosumab with placebo on prolonging bone metastasis-free survival in men with hormone refractory (androgen independent) prostate cancer who have no bone metastasis at baseline.

Detailed Description

Participants were randomized to receive denosumab 120 mg or placebo every 4 weeks (Q4W) until approximately 660 participants developed bone metastasis or died and the primary efficacy and safety analyses were completed.

All participants undergoing scheduled assessments were offered open-label denosumab 120 mg subcutaneous (SC) until they either developed a bone metastasis, obtained access to commercially available product in this setting, or for up to 3 years, whichever came first. For participants who ended participation before the open-label extension (OLE) phase or withdrew from investigational product during the OLE phase, their survival data was to be collected every 6 months for up to 3 years after their last dose of investigational product.

Participants in the Czech Republic and United Kingdom were enrolled under a separate protocol for the OLE phase per Health Authority request, and are reported separately (Study 20080585; NCT01824342).
