Inclusion Criteria: * Histologically confirmed adenocarcinoma of the prostate. * Biochemical disease progression following androgen deprivation and therapy with at least one antiandrogen defined as three rises in PSA with PSA determinations at least 4 weeks apart and each PSA value \> 0.2 ng/ml. * Four weeks since prior therapy with Flutamide. * Six weeks since prior therapy with Bicalutamide or Nilutamide. * Current PSA \> 5 ng/ml. * Testosterone \<50 ng/dL. * SGPT (ALT) \< 1.5 times upper limit of normal. * Fasting blood glucose \> 60 mg/dL. * ECOG performance status 0, 1 or 2. * No visceral or bony metastatic disease (Lymph node only metastases are allowed). * No prior chemotherapy for prostate cancer. * No current treatment with insulin or an oral hypoglycemic. * No history of treatment with octreotide analogs for prostate cancer. * No NYHA Class 3 or 4 cardiac status. Exclusion Criteria: * Diabetes Mellitus requiring medical therapy and/or that which is not controlled by dietary means (HbA1C\<6.0). * A history of gallstones that has been clinically significant.
