Study to Evaluate Safety and Effectiveness of Lenalidomide in Combination With Docetaxel and Prednisone for Patients With Castrate-Resistant Prostate Cancer
- Conditions
- Prostate Cancer
- Interventions
- Registration Number
- NCT00988208
- Lead Sponsor
- Celgene
- 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.

Group Intervention Description Docetaxel and Prednisone (DP) Placebo Oral placebo once each day on Days 1-14 of the treatment cycle; 75 mg/m2 docetaxel intravenously on Day 1; 5 mg prednisone orally twice each day on each day of the treatment cycle Docetaxel, Prednisone, Lenalidomide (DPL) Prednisone 25 mg lenalidomide orally once each day on Days 1-14; 75 mg/m2 docetaxel intravenously on Day 1; 5 mg prednisone orally twice daily on each day of the treatment cycle Docetaxel, Prednisone, Lenalidomide (DPL) Lenalidomide 25 mg lenalidomide orally once each day on Days 1-14; 75 mg/m2 docetaxel intravenously on Day 1; 5 mg prednisone orally twice daily on each day of the treatment cycle Docetaxel, Prednisone, Lenalidomide (DPL) Docetaxel 25 mg lenalidomide orally once each day on Days 1-14; 75 mg/m2 docetaxel intravenously on Day 1; 5 mg prednisone orally twice daily on each day of the treatment cycle Docetaxel and Prednisone (DP) Docetaxel Oral placebo once each day on Days 1-14 of the treatment cycle; 75 mg/m2 docetaxel intravenously on Day 1; 5 mg prednisone orally twice each day on each day of the treatment cycle Docetaxel and Prednisone (DP) Prednisone Oral placebo once each day on Days 1-14 of the treatment cycle; 75 mg/m2 docetaxel intravenously on Day 1; 5 mg prednisone orally twice each day on each day of the treatment cycle
- Primary Outcome Measures
Name Time Method Overall Survival (OS) 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 Outcome Measures
Name Time Method 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 PFS was the time from randomization to disease progression, or death, whatever occurred first. Progression criteria was met by analysis of target and non-target lesions as defined by Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 criteria. Progressive Disease (PD) is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum of the diameters while on study or the appearance of one or more new lesions; an increase of at least 5mm as a total sum. Lymph nodes identified as target lesions (≥ 15 mm diameter in short axis) will be followed and reported by changes in diameter of short axis; or the unequivocal progression of a non-target lesion defined as an increase in the overall disease burden based on the change in non-measurable disease that is comparable in scope to the increase required to declare PD for measurable disease; Two or more new bone lesions as detected by bone scan
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 Objective response (OR) is defined as having complete response (CR) or partial response (PR) as best overall response based on RECIST Criteria 1.1 and defines a CR = Disappearance of all target lesions except lymph nodes (LN); LN must have a decrease in the short axis to \<10mm; PR = 30% decrease in sum of diameters of target lesions taking as reference the baseline sum diameters; Progressed Disease (PD) = 20% increase in sum of diameters of target lesions taking as a reference the smallest sum of diameters and an absolute increase of ≥5 mm; the appearance of ≥1 new lesions; Stable Disease (SD)= Neither shrinkage to qualify for PR nor increase to qualify for PD taking the smallest sum diameters on study as reference. For non-target lesions a CR = Disappearance of all non-target lesions and all LN must be non-pathological in size \<10 mm; Non-CR/Non PD: persistence of one or more non-target lesions; PD = unequivocal progression of existing non-target lesions or appearance of new ones
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 A TEAE is defined as any AE occurring or worsening on or after the first dose of study drug and within 28 days after the last dose of study drug. A TESAE is defined as any serious adverse event (SAE) occurring or worsening on or after the first dose of study drug and within 28 days after the last dose of study drug. Safety and severity was assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.0; Severity of AEs were graded (including second primary malignancies) as Grade 1- Mild; Grade 2- Moderate; Grade 3- Severe; Grade 4- Life-threatening; Grade 5-Fatal;
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 Who Received Post-Study Therapies for advanced Prostate Cancer.
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 Second primary malignancies were monitored as events of interest and reported as serious adverse events throughout the course of the trial.
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 Time of Onset of Secondary Primary Malignancies was considered an event of interest
