Sorafenib in Treating Patients With Metastatic or Recurrent Prostate Cancer
A Phase II Study Of BAY 43-9006 (NSC 724772; CTEP IND# 69,896) In Patients With Hormone Refractory Prostate Cancer

RATIONALE: Sorafenib may stop the growth of tumor cells by blocking the enzymes necessary for their growth.

PURPOSE: This phase II trial is studying the effectiveness of sorafenib in treating patients who have metastatic or recurrent prostate cancer that has not responded to previous hormone therapy.

OBJECTIVES:

  • Determine the efficacy of sorafenib, as measured by prostate-specific antigen response, in patients with metastatic or recurrent hormone-refractory adenocarcinoma of the prostate.

Secondary

  • Determine the objective response rate and duration of response in patients treated with this drug.
  • Determine the tolerability and toxicity of this drug in these patients.
  • Determine time to treatment failure and overall survival in patients treated with this drug.
  • Explore the relationship between measures of ras/raf pathway activation (pERK) and response to treatment in these patients.

OUTLINE: This is a non-randomized, multicenter study.

Patients receive oral sorafenib twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients are followed at 4 weeks after going off study treatment and then periodically for survival. Patients with stable or responding disease, when they go off study treatment, are followed every 3 months until relapse or progression.

PROJECTED ACCRUAL: Approximately 15-25 patients will be accrued for this study within 12-18 months.
