NCT00847821

Brief Summary

This study is an observational study analyzing the biopsy samples collected from subjects that participated in Study 3115A1-303 (NCT00675688). These endometrial biopsy samples will be de-identified at an anatomical laboratory and then sent to a molecular biology lab where an RNA extraction and analysis will be performed. The purpose of this study is to compare specific endometrial gene regulation at the level of mRNA expression in samples from placebo, bazedoxifene/conjugated estrogens, and raloxifene treated groups with a known set of genes that have been previously identified to be associated with estrogenization, endometrial hyperplasia, and endometrial cancer.

Interventions

No dose taken during this study; however, this intervention was taken while study 3115A1-303 was ongoing. In the 3115A1-303 study, test article was supplied as bazedoxifene/CE tablets in capsules. The dosage was one capsule orally, once daily, at approximately the same time each day on a continuous regiment for 2 years, or until early discontinuation from the study.
