Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. Deslorelin combined with low-dose add-back estradiol and testosterone (given to replace hormones suppressed by deslorelin) may be effective in preventing breast cancer in at-risk women.

PURPOSE: This phase II trial is studying how well giving deslorelin together with estradiol and testosterone works in preventing breast cancer in premenopausal women who are at high risk for this disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

OBJECTIVES:

I. Assess the effects on the breast of treatment with the gonadotropin-releasing hormone agonist (GnRHA)-based regimen in breast cancer (BRCA) gene mutation carriers, including correlation of changes in mammographic and magnetic resonance imaging (MRI) densities with tissue morphometrics and biomarkers.

II. Evaluate perspectives about risk reduction options and impact on quality-of-life (QOL) measures of participation in the chemopreventive protocol and in risk reduction surgery.

OUTLINE:

GROUP 1: Patients receive deslorelin, estradiol, and testosterone intranasally once daily (QD) for 6 months. Patients then undergo planned risk reduction mastectomy.

GROUP 2: Patients receive deslorelin, estradiol, and testosterone intranasally QD for 10 months. Patients then undergo continued surveillance through 10 months.

After completion of study treatment, patients are followed up every 6 months for 2 years.
