Sulindac in Preventing Breast Cancer in Women at High Risk for Breast Cancer

Phase 1
Completed
Conditions
Breast Cancer
Registration Number
NCT00245024
Lead Sponsor
National Cancer Institute (NCI)
Brief Summary

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of sulindac may prevent breast cancer.

PURPOSE: This randomized phase I trial is studying the effects of sulindac, to prevent breast cancer, in women at high risk for breast cancer.

Detailed Description

OBJECTIVES:

Primary

* Determine the partitioning of sulindac and its metabolites in women at high risk for breast cancer by measuring drug and metabolite levels in nipple aspirate fluid (NAF) after 6 weeks of therapy.

Secondary

* Determine prostaglandin levels in the NAF of patients treated with this drug.

* Determine if NAG-1 levels are induced in the NAF of patients treated with this drug.

* Determine if C-reactive protein levels are reduced in the NAF of patients treated with this drug.

* Determine if NAG-1 levels and/or karyometric features in ductal epithelial cells are modulated in patients treated with this drug.

OUTLINE: This is a randomized, open-label study.

Patients undergo nipple aspirate fluid (NAF) collection. Patients are then randomized to 1 of 2 treatment arms.

* Arm I: Patients receive oral sulindac once daily.

* Arm II: Patients receive oral sulindac twice daily. In both arms, treatment continues for 6 weeks in the absence of disease progression or unacceptable toxicity. All patients then undergo a second NAF collection.

After completion of study treatment, patients are followed at 2 weeks.

PROJECTED ACCRUAL: A total of 30 patients (15 per treatment arm) will be accrued for this study.
