Satraplatin and Prednisone to Treat Prostate Cancer

Summary

Background: Satraplatin is an experimental drug that may be of benefit to patients with prostate cancer. Prednisone is approved for treating prostate cancer. The gene excision repair cross-complementing rodent repair deficiency complementation group 1 (ERCC1) helps repair cell damage caused by satraplatin. It is possible that patients who have a variant of this gene will not benefit from treatment with satraplatin because the drug will not be able to damage the cancer cells effectively. Objectives: To determine if satraplatin may help treat prostate cancer in patients with certain variants of the ERCC1 gene. Eligibility: Patients with advanced androgen-independent prostate cancer whose disease has not responded to hormonal therapy or at least one type of chemotherapy and whose x-rays, scans or other tests have shown their cancer to be spreading. Design: Participants have a blood test to determine if they have a variant of the ERCC1 gene. Participants take satraplatin by mouth every day for 5 consecutive days out of every 35 days and prednisone by mouth every day. These 35-day treatment cycles may continue for 6 months or longer, depending on the benefits and side effects of the treatment. During the treatment period, patients undergo the following tests and procedures: * Blood tests on days 1 of the treatment cycle. * Weekly blood draws for the first 3 treatment cycles. * Imaging studies (e.g., bone scans, computed tomography (CT) scans) every two cycles to determine the response to treatment. * Surgical or medical suppression of testosterone in patients whose cancer cells continue to grow due to exposure to the hormone....
