Detailed Description:

OBJECTIVES:

Primary

Establish the maximum tolerated dose, dose-limiting toxicity, and a recommended phase II dose of absorption-enhanced diindolylmethane (BioResponse-DIM^® [BR-DIM]) in patients with nonmetastatic, hormone-refractory prostate cancer and rising serum prostate-specific antigen (PSA) levels.
Evaluate the toxicities of BR-DIM.

Secondary

Evaluate the plasma pharmacokinetics of twice daily oral administration of BR-DIM in this patient population.
Evaluate the effect of BR-DIM supplementation on serum PSA level.
Correlate changes in expression levels of lymphocytes NF-kB with serum PSA levels in patients taking BR-DIM supplementation.
Determine quality of life measures in patients taking BR-DIM supplementation.

OUTLINE: This is an open-label, dose-escalation study.

Patients receive oral absorption-enhanced absorption-enhanced diindolylmethane (BioResponse-DIM^® [BR-DIM]) twice daily on days 1-28. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of BR-DIM until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. At least 6 patients are treated at the MTD.

Quality of life is assessed at baseline, on day 1 of each course, and at the completion of study therapy.

PROJECTED ACCRUAL: A total of 36 patients will be accrued for this study.
