Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This randomized phase I trial studies the side effects and the best dose of Se-methyl-seleno-L-cysteine or selenomethionine in preventing prostate cancer in healthy participants. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of Se-methyl-seleno-L-cysteine or selenomethionine, two different types of selenium compounds, may prevent prostate cancer from forming.
