Broccoli Sprout Intervention in Qidong, P.R. China
In Brief
A Phase 2 clinical trial evaluating Broccoli Sprout Extract Beverage and placebo beverage for Environmental Carcinogenesis. Completed, enrolled 291 participants across 1 site.
Detailed Summary
This study is a 12 week placebo-controlled Phase II broccoli sprout intervention to be conducted in Qidong, P.R. China. One thousand two hundred people from the farming townships will be screened and three hundred eligible individuals will be enrolled in the study. Participants will be randomized into two treatment groups: one will receive a juice beverage containing glucoraphanin- and sulforaphane-rich broccoli sprout extract, pineapple juice, lime juice, and water and the other will receive a placebo beverage containing pineapple juice, lime juice and water. Participants will drink their assigned beverage every evening and provide biweekly urine samples and monthly blood samples. The principal endpoints of this study are pharmacokinetic evaluation of elimination of glucoraphanin/sulforaphane and their metabolites in urine and pharmacodynamic evaluation through measures of urinary levels of exposure biomarkers for dietary and air-borne toxins, which are known to be high in this population.
