NCT00245024
First received: October 25, 2005
Last updated: May 1, 2013
Last verified: October 2011
  Purpose

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.

Secondary Outcome Measures:
  • Prostaglandin (PGE2) levels in NAF before and after 6 weeks of treatment [ Designated as safety issue: No ]
  • NAG-1 induction and C-reactive protein (CRP) reduction before and after 6 weeks of treatment [ Designated as safety issue: No ]
  • Magnitude of change and dose response of PGE2, NAG-1, and CRP in NAF before and after 6 weeks of treatment [ Designated as safety issue: No ]

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.
