Phase Ib 9cUAB30 in Early Stage Breast Cancer to Evaluate Biologic Effect
The purpose of this study is to determine if the study drug called 9cUAB30 has an effect on growth of cancer cells. 9cUAB30 is an investigational drug that has been shown in animals to prevent breast cancers. We will be looking to see if there are any changes in the breast cancer cells that may indicate that the study drug could be used in the future to help prevent breast cancer. We will also be looking at the level of 9cUAB30 in the blood of the first six participants.
All women enrolled in this study will receive the study drug 9cUAB30 by mouth daily for 14-28 days. You should take the study medication at bedtime at least two hours after last eating. After taking your study medication, you must wait an hour before eating anything. The first 6 participants will receive 240mg daily and additional blood draws to test the level of drug absorbed in the blood. If the 240 mg dose of 9cUAB30 does not provide a higher level of drug in the bloodstream than was observed after 160mg in our prior study, then the remaining participants will receive 160mg daily. Women treated with 9cUAB30 in this study will have their tumor biopsy and surgical samples compared to leftover tumor biopsy or surgical samples from women with similar stages of breast cancer, but not treated with 9cUAB30 to determine if 9cUAB30 reduced breast cancer cell growth or not in treated women
