Primary Outcome Measures:
- Determine maximum tolerated dose and dose limiting toxicity for the combination of Satraplatin and radiation therapy. [ Time Frame: Serum chemistry and CBC will be evaluated weekly. PSA level will be evaluated on Day on of week 5. ]
Secondary Outcome Measures:
- PSA Response, Time to PSA Response, Duration of PSA response, Secondary Biochemical Recurrence Free Survival, Time to Biochemical Recurrence, Effect of Satraplatin on Serum Testosterone Levels, Safety and Tolerability. [ Time Frame: PSA level will be evaluated on Day on of week 5. There will be an end of treatment visit within 30 days of the last RT-Satraplatin treatment. PSA will be drawn every 3 m for 2 years, then every 6 m until evidence of either PSA or clinical progression. ]

There were approximately 232,000 cases of prostate cancer diagnosed in the US in 2005. Most patients present with localized disease and undergo curative therapy, either radical prostatectomy (RP) or radiation therapy (RT). Although most men are cured after this therapy, approximately 30,000-50,000 annually in the US will develop recurrence after RP. For most of these patients, recurrence will be defined by biochemical recurrence (BCR), a rise in PSA with no other documented evidence of recurrence. Patients with BCR typically receive radiation therapy to the prostate bed. However, about 50% of these patients will develop distant recurrence outside of the pelvis and require systemic therapy.
Satraplatin is a third generation orally administered platinum compound. Early clinical studies demonstrated activity in tumors of the ovary and lung in addition to prostate cancer. Satraplatin has shown activity in prostate cancer in Phase II studies and has been evaluated in a pivotal Phase III study (The SPARC trial)as a single agent as second line therapy.
