Docetaxel, Thalidomide, Prednisone, and Bevacizumab to Treat Metastatic Prostate Cancer

Summary

This is a Phase II study of docetaxel, bevacizumab, prednisone and thalidomide in patients with androgen independent metastatic prostate cancer who are previously untreated with chemotherapy. The primary objective of this study is to determine if the combination of docetaxel, thalidomide and bevacizumab is able to be associated with a sufficiently high proportion of patients with a prostate-specific antigen (PSA) response to be worthy of further investigation in metastatic prostate cancer. We will also be looking at multiple secondary endpoints. These will include possible pharmacokinetic interactions among the study agents, potential correlation between patient genotype and efficacy of treatment. We will also be looking for circulating tumor cells in blood before and after treatment. Additionally we will be monitoring the tolerability of the regimen and survival duration as endpoints as well. We hope to use this trial to build on the promising results seen in our thalidomide/docetaxel protocol where there was a significant PSA decline and a trend toward survival benefit.
