Overview
Brief Summary
The purpose of the study is to determine whether lenalidomide is safe and effective for use in combination with docetaxel and prednisone for the treatment of subjects with metastatic Castrate-Resistant Prostate Cancer.
The addition of lenalidomide to docetaxel and prednisone is proposed to increase the life expectancy of these subjects.
Detailed Description
In November 2011, the Data Monitoring Committee concluded it was unlikely that the study would meet its primary endpoint of overall survival (OS) and recommended that the study be stopped. The study was terminated in accordance with this recommendation. All sites were instructed to immediately discontinue all patients from experimental lenalidomide/placebo treatment administered either in combination with chemotherapy or as a single agent following chemotherapy discontinuation. Subsequently, Protocol Amendment 3 was issued to provide for the following: To continue to collect information on Second Primary Malignancies (SPMs) and additional treatments for Prostate Cancer in all randomized subjects during survival follow-up. To continue to provide docetaxel and prednisone for up to 10 cycles to subjects randomized at non-US sites who were ongoing in the CC-5013-PC-002 protocol when the decision was made to discontinue lenalidomide/placebo and who were experiencing benefit as per investigator discretion. For subjects who had exceeded 10 cycles of docetaxel and prednisone at the time of Protocol Amendment 3 approval, an additional two cycles were provided. All references to dosing and study procedures pertaining to the safety, efficacy, and exploratory endpoints of lenalidomide/placebo were discontinued as part of Protocol Amendment 3.

Outcomes
Primary Outcomes
Overall Survival (OS)
Time Frame: From randomization until death from any cause up to the cut-off date of 13 January 2012; up to approximately 26 months
Overall survival (OS) was the time from the date of randomization to the date of death from any cause. If no death was reported for a participant before the cut-off date for OS analysis, OS was censored at the last date at which the participant was alive. The median OS was calculated based on Kaplan-Meier estimates and corresponding 95% confidence interval (CI) was calculated using the method provided by Brookmeyer and Crowley.
Secondary Outcomes
- Progression-Free Survival (PFS)(From randomization until disease progression or death from any cause; up to the cut-off date of 13 Jan 2012; maximum time on study was approximately 26 months)
- Percentage of Participants With an Objective Response According to Response Evaluation Criteria in Solid Tumors - RECIST Version 1.1 Criteria(From day 1 to data cut-off 13 January 2012; maximum time on study was approximately 26 months)
- Number of Participants With Treatment Emergent Adverse Events (AEs)(From the time from of first dose of study drug administration to 28 days after the last dose of study drug and up to the data cut off date of 13 January 2012; the maximum duration of study drug was 93 weeks for DP and 90.6 weeks for DPL)
- Percentage of Participants Who Received Post-Study Therapies(The date when the first consent form was signed to the last date of AE data collection;up to 5 years; up to the date of the final data analysis date of 20 April 2017)
- Percentage of Participants With Secondary Primary Malignancies During the Course of the Trial(The date when the first consent form was signed to the last date of AE data collection; up to the date of the final data analysis date of 30 November 2016; 7 years and 19 days)
- Time to Onset of Secondary Primary Malignancies(The date when the first consent form was signed to the last date of AE data collection; up to the date of the final data analysis date of 30 November 2016; 7 years and 19 days)
