A Phase 2 Trial of Bevacizumab, Lenalidomide, Docetaxel, and Prednisone (ART-P) for Treatment of Metastatic Castrate-Resistant Prostate Cancer

Detailed Summary

Background: * Prednisone and docetaxel have been used successfully in treating patients with prostate cancer, either when used alone or in combination with other agents. Researchers believe that these anticancer effects can be increased by giving them in this specific combination. * A previous study at the National Cancer Institute combined docetaxel and prednisone with bevacizumab and thalidomide. The results of this study were promising; however, most patients in the study required a dose reduction of thalidomide because of its side effects. * Lenalidomide, a drug similar to thalidomide, may have less severe side effects. Based on previous studies, lenalidomide is well tolerated in patients with solid tumors when used alone or in combination with docetaxel, and it may be a good substitute for thalidomide. Objectives: * To determine if lenalidomide is an appropriate and effective substitute for thalidomide in treating prostate cancer. * To evaluate the safety and effectiveness of bevacizumab, lenalidomide, docetaxel, and prednisone as a prostate cancer treatment, and to study any side effects. Eligibility: \- Men 18 years of age and older who have been diagnosed with metastatic prostate cancer that has not responded to standard treatment, including surgical removal of the testicles or treatment with androgen (sex-hormone) suppressing drugs. Design: * Participants will have a complete medical history and physical examination before beginning the study. * Patients will be treated with 21-day cycles with a combination of four drugs: * (1) Docetaxel, which will be given into a vein for 60 minutes on the first day of each 21-day cycle. Patients will take dexamethasone (a steroid agent) before and after taking docetaxel. * (2) Prednisone, which will be taken by mouth daily. * (3) Bevacizumab, which will be given through a vein over 30 to 90 minutes on the first day of each 21-day cycle following the infusion of docetaxel. * (4) Lenalidomide, which will be taken by mouth during the first 2 weeks of each 21-day cycle. The dose of lenalidomide may be adjusted if side effects develop. * Patients will also receive enoxaparin, a subcutaneous injection administered daily, to prevent blood clots and/or pegfilgrastim, a subcutaneous injection on day 2 of each cycle, to improve white blood cell counts, as directed by researchers.
