PURPOSE: This randomized phase I trial is studying the side effects and best dose of lycopene in healthy male participants.
- Compare the toxicity and safety of 2 different doses of oral lycopene in healthy male participants.
- Compare the pharmacokinetics of 2 different doses of this drug in these participants.
- Determine the toxicity and pharmacokinetics needed to proceed to a large phase II/III study in men at high risk for prostate cancer.
OUTLINE: This is a randomized, crossover study. Participants are randomized to 1 of 2 treatment arms.
- Arm I: Participants receive high-dose oral lycopene once or twice a day for 14 days. After 2 weeks of a lycopene-free period, participants crossover and receive high-dose lycopene at the alternative daily schedule (once or twice a day) for 14 days.
- Arm II: Participants receive low-dose oral lycopene once or twice a day for 14 days. After 2 weeks of a lycopene-free period, participants crossover and receive low-dose lycopene at the alternative daily schedule (once or twice a day) for 14 days.
Treatment continues in the absence of unacceptable toxicity.
Participants adhere to dietary restrictions for 2 weeks at baseline, 2 weeks during study treatment, and 2 weeks during pharmacokinetic sampling.
Blood samples are collected periodically at baseline and during study treatment for pharmacokinetic studies.
PROJECTED ACCRUAL: A total of 20 participants will be accrued for this study.

The purpose of this study is to determine whether dietary lycopene supplementation lowers serum prostate specific antigen(PSA) in men with high grade intraepithelial neoplasia (HGPIN).
The aim of this pilot study is to conduct a dietary intervention for overweight (body maas index BMI≥25) and obese (BMI≥30) pregnant women in two maternity care clinics and explore the...

Although about 90% of lycopene in dietary sources occurs in the linear all-trans conformation, a large proportion of the lycopene found in human tissues is of the cis-isomer type, notably (5Z)-lycopen...
This brief report examines the implementation of dietary intervention utilizing the specific carbohydrate diet (SCD) for the management of gastrointestinal issues in a 4 year old boy diagnosed with A...
Patients with heart failure (HF) remain at high risk for future events despite medical and device therapy. Dietary sodium reduction is often recommended based on limited evidence. However, it is not k...
Diet intervention in obese adults is the first strategy to induce weight loss and to improve insulin sensitivity. We hypothesized that improvements in insulin sensitivity after weight loss from a shor...
To explore the experiences of people recently diagnosed with prediabetes and overweight or obese in making dietary changes following a six-month primary care nurse-delivered dietary intervention pilot...
A study in which observations are made before and after an intervention, both in a group that receives the intervention and in a control group that does not.
A study that uses observations at multiple time points before and after an intervention (the "interruption"), in an attempt to detect whether the intervention has had an effect significantly greater than any underlying trend over time.
Iron or iron compounds used in foods or as food. Dietary iron is important in oxygen transport and the synthesis of the iron-porphyrin proteins hemoglobin, myoglobin, cytochromes, and cytochrome oxidase. Insufficient amounts of dietary iron can lead to iron-deficiency anemia.
Narrowing of the caliber of the BRONCHI, physiologically or as a result of pharmacological intervention.
Phosphorus used in foods or obtained from food. This element is a major intracellular component which plays an important role in many biochemical pathways relating to normal physiological functions. High concentrations of dietary phosphorus can cause nephrocalcinosis which is associated with impaired kidney function. Low concentrations of dietary phosphorus cause an increase in calcitriol in the blood and osteoporosis.
