Brief Summary: RATIONALE Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer The use of lycopene may be an effective way to prevent prostate cancer
PURPOSE Phase I trial to study the effectiveness of lycopene in preventing prostate cancer
Detailed Description: OBJECTIVES
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 Determine the pharmacokinetics of this regimen in this population 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
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
PROJECTED ACCRUAL A total of 5-25 patients will be accrued for this study
