Testing Acolbifene vs Low Dose Tamoxifen to Prevent Breast Cancer

Official Title Phase IIA Trial of Acolbifene (20 mg) vs Low Dose Tamoxifen (5 mg) in Pre-menopausal Women at High Risk for Development of Breast Cancer

Purpose

This study wants to see if two medicines, acolbifene or a small dose of tamoxifen, can lower the chance of getting breast cancer in women who are at high risk before menopause.

Acolbifene and tamoxifen work by blocking estrogen, a hormone that can help cancer cells grow. By blocking estrogen, these medicines may lower the chance of breast cancer in women at high risk. The study lasts between 6 and 8 months.

If this study works, it could give us new ways to help prevent breast cancer.

Could this study be right for you?
