Pharmacokinetics and Hepatic Safety of EGCG

A trial to assess the pharmacokinetics and hepatic safety of EGCG in women with and without uterine fibroids.

This will be a randomized, multi-center, pharmacokinetics and hepatic safety trial of EGCG with 36 total patients in 3 treatment arms. 36 women will be randomized to one of the following groups: EGCG daily alone, EGCG daily with clomiphene citrate and EGCG daily with letrozole. The randomization scheme will be stratified for age groups 18-29 and 30-40 and presence of uterine fibroids. The pharmacokinetics and hepatic safety of EGCG with clomiphene citrate and letrozole are unknown. The trial conducted in women with and without fibroids will allow comparisons between these groups. The results of this study will be used to confirm hepatic safety for the larger multi-center FRIEND study.
