Phase I/II Study of Sorafenib Concurrent With Androgen Deprivation and Radiotherapy in the Treatment of Intermediate- and High-Risk Localized Prostate Cancer

Leuprolide acetate (a luteinizing hormone releasing hormone (LHRH) agonist) and Bicalutamide
(an anti-androgen) are hormonal agents which are commonly used to reduce testosterone blood
level for prostate cancer treatment. Intensity modulated external beam radiotherapy is a
standard treatment for localized prostate cancer. Previous studies have shown that
combining hormonal therapy and radiation is more effective than radiation alone.
Unfortunately, significant percentages (50-75%) of patients still relapse. Sorafenib reduces
the growth of cancer cells and has proven effective in the treatment of solid tumors
including kidney and liver cancer. This drug is approved by the FDA for treatment kidney and
liver cancer. The study investigators believe that adding sorafenib to standard treatment,
comprising hormonal therapy and radiation, might be more effective then standard hormonal

Inclusion Criteria:

- Patients must have histologically confirmed intermediate or high risk prostate
adenocarcinoma. Intermediate risk disease comprises T2b/c tumors, Gleason 7
histology, or PSA 10-20. High risk tumors comprise T3-4, Gleason 8 or higher
histology, or PSA greater than 20.

- Age > 18 years.

- Life expectancy of greater than 5 years.

- Patients must have normal organ and marrow function.

- No pelvic lymph node metastases based on pelvic CT scan or MRI.

- No bone metastasis. A whole body bone scan is required to rule out metastatic

Exclusion Criteria:

- Any previous, radiotherapy, or chemotherapy, or more than 4 weeks of androgen
deprivation hormonal therapy for the treatment of prostate adenocarcinoma.

- Patients may not be receiving any other investigational agents.

- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to sorafenib or other agents used in this study.

- Known human immunodeficiency virus (HIV) infection or chronic Hepatitis B or C.

- Patients receiving anti-coagulation treatment with an agent such as warfarin or
heparin will not be allowed to participate.
