Indole-3-Carbinol in Preventing Cancer in Healthy Participants
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of indole-3-carbinol may prevent cancer.
PURPOSE: This randomized phase I trial is studying the side effects and best dose of indole-3-carbinol and to see how well it works compared to placebo in preventing cancer in healthy participants.
Unspecified Adult Solid Tumor, Protocol Specific
|Study Design:||Allocation: Randomized
Primary Purpose: Prevention
|Official Title:||Phase I Ascending Single Dose Pharmacokinetics (PK) and Safety Study of 3,3' Di-Indolymethane (DIM) Nutritional Product|
|Study Start Date:||November 2004|
- Determine the maximum tolerated dose of indole-3-carbinol in healthy participants.
- Determine the safety and tolerability of this drug in these participants.
- Determine the pharmacokinetics of this drug in these participants.
- Determine the effects of this drug on selected markers of sexual function in these participants.
- Determine the effects of this drug on markers of susceptibility to cancer in these participants.
OUTLINE: This is a randomized, double-blind, placebo-controlled, dose-escalation study. Participants at each dose level are randomized to 1 of 2 treatment arms.
- Arm I: Participants receive a single dose of oral indole-3-carbinol on day 1.
- Arm II: Participants receive a single dose of oral placebo on day 1. Cohorts of 3 participants receive escalating doses of indole-3-carbinol until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 1 of 3 participants experiences dose-limiting toxicity. An additional cohort of 3 participants is treated at the MTD.
Participants are followed on days 2, 3, and 6.
PROJECTED ACCRUAL: A total of 24 participants (18 in arm I and 6 in arm II) will be accrued for this study.
