Oral CDB-4124 vs. Placebo in Stage I-II Primary Breast Cancer

Summary

The purpose of this study is to determine whether or not the medication that blocks the effects of the hormone progesterone (CDB-4124 or Proellex) will decrease the growth rate of breast cancer cells as compared to a placebo. CDB-4124 (also called Proellex) is a medication that works against the hormone, progesterone. The researchers in this study would like to compare changes in breast cancer cells of women who have taken CDB-4124 prior to surgery to those from women who have taken a placebo pill prior to surgery.
