Sorafenib in Treating Patients With Metastatic or Recurrent Prostate Cancer

This study has been completed.
National Cancer Institute (NCI)
Information provided by (Responsible Party):
Canadian Cancer Trials Group ( NCIC Clinical Trials Group ) Identifier:
First received: October 6, 2004
Last updated: September 27, 2011
Last verified: September 2011

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.

Condition Intervention Phase
Prostate Cancer Drug: sorafenib tosylate Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Study Of BAY 43-9006 (NSC 724772; CTEP IND# 69,896) In Patients With Hormone Refractory Prostate Cancer

Primary Outcome Measures:
  • Prostate-specific antigen response and/or progression [ Time Frame: 2 years ]

Secondary Outcome Measures:
  • Objective response and/or progression [ Time Frame: 2 years ]
  • Tolerability and toxicity [ Time Frame: 2 years ]
  • Time to treatment failure and overall patient survival [ Time Frame: 2 years ]

Enrollment: 28
Study Start Date: July 2004
Study Completion Date: January 2011
Primary Completion Date: September 2006 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: sorafenib tosylate
    BAY 43-9006 given orally at 400 mg BID in a 28 day cycle
Detailed Description:


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


  • 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.
