Clinical Trial Summary

PURPOSE: Randomized phase I trial to determine the effectiveness of genistein in treating patients who have stage II, stage III, or stage IV prostate cancer.

Description:

OBJECTIVES: I. Determine the safety and pharmacokinetics of genistein in patients with stage II, III, or IV prostate cancer.

OUTLINE: This is a randomized, double blind, placebo controlled study. Patients are randomized to one of two treatment arms. Arm I: Patients receive oral genistein twice daily. Arm II: Patients receive oral placebo twice daily. Treatment continues for 3 months in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 24 patients will be accrued for this study within 6 months.
