Summary

This trial is testing a low dose of tamoxifen to see if it can reduce breast density in women who have a higher risk of breast cancer. Breast density is a known risk factor for breast cancer

Who is the study for?

This trial is for premenopausal women at higher than average risk for breast cancer, particularly those with dense breasts. The study aims to find the best dose of Tamoxifen that can reduce breast density and thus lower the risk of developing breast cancer.

What is being tested?

The RENAISSANCE Trial is testing low-dose Tamoxifen's effectiveness in reducing breast density among high-risk women. It includes assessments like questionnaires, biopsies, biospecimen collection, and mammography to monitor changes and responses.

What are the potential side effects?

Tamoxifen may cause side effects such as hot flashes, vaginal dryness or discharge, menstrual irregularities, fatigue, mood swings, and a slight increase in the risk of blood clots.

Experimental Treatment

Group I: Prevention (tamoxifen)Experimental Treatment5 Interventions

Participants receive tamoxifen 5mg PO QD for 6 months. Participants with aDAR \>= 10% on mammogram at 6 months continue receiving tamoxifen 5mg PO QD for 12 months. Participants with aDAR \< 10% at 6 months are escalated to receive tamoxifen 10mg PO QD for 6 months. Participants with aDAR \>= 10% after 6 months of tamoxifen 10mg continue receiving tamoxifen 10 mg PO QD for 6 months. Participants with aDAR \< 10% after 6 months of tamoxifen 10mg are given the option of continuing tamoxifen 10mg or escalating to receive tamoxifen 20mg PO QD for 6 months. Participants undergo mammography and collection of blood samples at screening and on study. Participants may optionally undergo biopsy at screening and on study.
