A Phase II Biomarker Trial of Gelatin Encapsulated Extract of American Ginseng Root (LEAG) in Breast Cancer

Completed · Phase 2

Conditions studied: Breast Cancer

In brief

This study was designed to explore the changes brought about by gelatin encapsulated extract of American Ginseng Root (LEAG) in breast cancer tumors and surrounding normal breast epithelial cells. Various tumor biomarkers, as well as inflammatory mediators, will be examined in tissue following LEAG treatment.
