Official title

Randomized IIB Study of the Effect of Bazedoxifene Plus Conjugated Estrogens on Breast Imaging and Tissue Biomarkers in Peri or Post-Menopausal Women at Increased Risk for Development of Breast Cancer

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Women at risk for development of breast cancer and experiencing vasomotor menopausal symptoms (hot flashes) will be randomized to bazedoxifene (BZA) plus conjugated estrogens (CE) for 6 months versus a wait list control. Two risk factors for development of breast cancer will be studied pre-study and after 6 months: fibroglandular volume (FGV) on mammogram as assessed by Volpara software and proliferation by Ki-67 immunocytochemistry in benign breast tissue acquired by random periareolar fine needle aspiration (RPFNA). Change in biomarkers will be compared between groups.
