Eligibility criteria:

        Inclusion Criteria:

          -  Voluntary written informed consent

          -  Histopathologic diagnosis of prostatic adenocarcinoma with evidence of progression
             despite adequate castration (testosterone < 50 ng/dL)

          -  Progressive disease after taxane-based chemotherapy (docetaxel or paclitaxel, single
             agent or combination regimens, weekly or every 21 day schedules)

          -  Patients who discontinued taxane- based chemotherapy because of toxicity will be
             eligible as long as there is evidence of progressive disease

          -  Minimum of 4 weeks period from last chemotherapy infusion to registration (this does
             not apply to steroid use which is permitted). Estramustine needs to be discontinued at
             least 6 weeks prior to first day of treatment on protocol

          -  A minimum of 4 weeks off bicalutamide, nilutamide, megestrol acetate ketoconazole,
             diethylstilbestrol (DES). Minimum of 2 weeks off flutamide

          -  Reductase inhibitors will be allowed if initiated at least 2 months prior to
             registration

          -  No concurrent investigational therapy

          -  Complementary and Alternative Medicine (CAM) products will be permitted as long as
             patients have been receiving them for at least 2 months. Initiation of new CAM
             products while on protocol will be discouraged.

          -  Ongoing androgen deprivation therapy (orchiectomy, gonadotropin-releasing hormone
             (GnRH) agonist or antagonist)

          -  Adequate bone marrow, liver and renal function as assessed by the following:

               -  Hemoglobin ≥ 9.0 g/dl

               -  Absolute neutrophil count (ANC) ≥ 1,500/mm3

               -  Platelet count ≥ 100,000/mm3

               -  Total bilirubin ≤ 1.5 times upper limit of normal (ULN)

               -  ALT and AST ≤ 2.5 times the ULN ( ≤ 5 x ULN for patients with liver involvement)

               -  Creatinine ≤ 1.5 times the ULN

          -  International normalized ratio (INR) < 1.5 or a Prothrombin (PT)/Partial
             thromboplastin time (PTT) within normal limits. Patients receiving anti-coagulation
             treatment with an agent such as warfarin or heparin may be allowed to participate. For
             patients on warfarin, the INR should be measured prior to initiation of sorafenib and
             monitored at least weekly, or as defined by the local standard of care, until INR is
             stable.

          -  ECOG performance status ≤ 2

          -  Baseline left ventricular ejection fraction (LVEF) ≥ 50%

          -  Life expectancy ≥ 3 months

          -  Patients must agree to use adequate contraception prior to study entry, during the
             study and for at least three months after the last administration of sorafenib

        Exclusion Criteria:

          -  More than one line of prior cytotoxic chemotherapy in the metastatic setting, previous
             adjuvant chemotherapy will be allowed
