Study Combining Imatinib Mesylate (Gleevec) With Sorafenib in Patients With Androgen-independent Prostate Cancer (AIPC)

Gleevec and Sorafenib have modest efficacy in androgen-independent prostate cancer (AIPC) and the fact that both agents can be given orally with what appears to be tolerable side effects, we hypothesize that combining both agents may provide patients with another effective regimen in a disease where therapeutic options are limited. This study is designed to investigate the safety of combining Gleevec and Sorafenib as well as feasibility in AIPC patients who have failed one or more lines of systemic chemotherapy. Once safety is established, a follow-up phase II study will commence to investigate efficacy.
