Alternate Title

Lycopene In Preventing of Prostate Cancer

Basic Trial Information

Objectives

1. Determine any dose limiting toxicities and the maximum tolerated dose of lycopene administered orally as a food based delivery system in healthy male subjects 18-45 years of age for the chemoprevention of prostate cancer.
2. Determine the pharmacokinetics of this regimen in this population.
3. Determine the dose range of this regimen to be used in the 3 month multiple dose study, based on the toxicity, pharmacokinetics and feasibility resulting from the present study in this population.

Expected Enrollment

A total of 5-25 patients will be accrued for this study.

Outline

This is a dose-escalation study.

Patients receive a single dose of oral lycopene in a mixture of tomato paste, water, and olive oil over 15 minutes on day 1. Patients are asked to maintain a diet that contains negligible carotinoid for 28 days.

Cohorts of 5 patients receive escalating doses of lycopene until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 5 patients experience dose limiting toxicities.

Patients are followed weekly for 4 weeks.
