A Phase II Trial of Polyphenon E for Cervical Cancer Prevention

National Cancer Institute (NCI)·interventional·Posted Mar 17, 2006·Updated May 5, 2015

In Brief

A Phase 2 clinical trial evaluating placebo, defined green tea catechin extract, and 1 other intervention for Cervical Cancer and 2 related conditions. Completed, enrolled 98 participants across 1 site.

Detailed Summary

This randomized phase II trial is studying green tea extract to see how well it works compared to a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia. Chemoprevention is the use of certain substances to keep cancer from forming, growing, or coming back. The use of green tea extract may stop cervical cancer from forming in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia. It is not yet known whether green tea extract is more effective than a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia.
