Breast Cancer Clinical Trial

Breast Cancer BRCA1 Carriers: a Pilot Study

Summary

The purpose of this study is to examine how a single dose of MIFEPREX® (mifepristone) affects the breast tissue in patients with BRCA1 (a gene that normally acts to restrain the growth of cells in the breast, but if it mutates may lead to breast cancer) mutations undergoing a planned prophylactic mastectomy (having one or both breasts removed).

Full Description

This is a single arm, prospective, observational trial enrolling up to 10 patients within Indiana University Simon Comprehensive Cancer Center. Eligible women will be consented to undergo breast biopsy 2-6 days prior to prophylactic mastectomy and take one dose of mifepristone 2 days prior to prophylactic mastectomy. If the initial biopsy is obtained on Day -2, the mifepristone should be taken AFTER the biopsy. Tissue from the ipsilateral breast will be taken at the time of mastectomy.

Primary Objective To determine the impact of a single 200 mg dose of mifepristone on gene expression and metabolomic alterations in breast tissue of women with BRCA1 mutations who are planning prophylactic mastectomy.
