A Study of BAY 43-9006 in Combination With Bicalutamide in Patients With Chemo-Naïve Hormone Refractory Prostate Cancer
To determine the efficacy of BAY 43-9006 in combination with bicalutamide in patients with chemo-naïve hormone-refractory prostate cancer.
That there will be PSA response when BAY 43-9006 in combination with bicalutamide is given to patients with chemo-naïve hormone-refractory prostate cancer.

Drug: BAY 43-9006
The biologic and clinical activity and tolerability of BAY 43-9006, the therapeutic needs of the proposed patient population, and the experimental evidence in support of targeting the VEGF/VEGFR and MAPK pathways in combination with androgen receptor blockade in prostate cancer, provides a strong rationale for the proposed phase II trial to evaluate the tolerability and anti-cancer activity of combined treatment with the non-steroidal anti-androgen bicalutamide with the multi-targeted kinase inhibitor BAY 43-9006 in patients with prostate cancer that is progressing after castration therapy.
The primary study objective is to define the efficacy (i.e. post treatment decrement in PSA (PSA response)) of BAY 43-9006 in combination with bicalutamide in patients with chemo-naïve hormone-refractory prostate cancer.
- To determine the safety and tolerability of BAY 43-9006 given in combination with bicalutamide in patients with HRPC.
- To determine the time to treatment failure, PSA progression and disease progression in HRPC patients treated with BAY 43-9006 in combination with bicalutamide.
- To determine objective response rates in HRPC patients with measurable disease treated with BAY 43-9006 in combination with bicalutamide.
This is a phase II clinical trial in patients with androgen independent prostate cancer which will evaluate the therapeutic activity and safety profile of BAY 43-9006 given orally at the recommended phase II dose of 400 mg PO BID continuously in combination with bicalutamide 50 mg PO daily continuously. Each 4 week period will be considered 1 cycle. Doses will be adjusted for toxicity.
Primary Endpoint The primary endpoint for this study will be the rate of PSA-response of the combination for patients with rising PSA post castration therapy.
Secondary endpoints will include time to treatment failure, time to PSA progression, duration of PSA response, median survival time, 1 year survival rate, objective tumor response rate and stable disease rate as defined by the RECIST criteria, response duration, and incidence of toxicities by NCI CTCAE.
