RATIONALE: Efavirenz may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PURPOSE: This phase II trial is studying how well efavirenz works in treating patients with metastatic prostate cancer.

Condition Intervention Phase
Prostate Cancer Drug: efavirenz Phase 2

Study Type: Interventional
Study Design: Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Trial to Assess the Efficacy of Efavirenz in Metastatic Patients With Androgen-independent Prostate Cancer

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Non-PSA progression rate at 3 months

Secondary Outcome Measures:
  • PSA response rate at 3 months
  • Overall survival
  • PSA progression-free survival (PFS)
  • Symptomatic PFS
  • LINE 1 methylation level at baseline and 3 months
  • Efavirenz blood concentration at 1 and 3 months
  • Safety and tolerability as assessed by the incidence and type of adverse events according to NCI CTCAE, clinically significant laboratory abnormalities, and vital signs

Estimated Enrollment: 60
Study Start Date: May 2008
Estimated Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Detailed Description:



  • To assess the effect of efavirenz on the non-PSA progression rate at 3 months in patients with castration-refractory metastatic prostate cancer.


  • To assess the effect of efavirenz on the PSA response at 3 months.
  • To assess the effect of efavirenz on overall survival.
  • To assess the effect of efavirenz on PSA progression-free survival.
  • To assess the effect of efavirenz on symptomatic progression-free survival.
  • To assess the tolerability and safety profile of efavirenz.

OUTLINE: This is a multicenter study.

Patients receive oral efavirenz once daily in the absence of disease progression or unacceptable toxicity.
