Brief Summary:

RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen or LY353381 may fight breast cancer by blocking the use of estrogen.

PURPOSE: This randomized phase I trial is studying how well tamoxifen works on the biomarkers of the tumor tissue, compared with LY353381, in treating women with newly diagnosed breast cancer.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: arzoxifene hydrochloride Drug: tamoxifen citrate Phase 1

Detailed Description:


  • Determine whether LY353381 hydrochloride or tamoxifen administered in the interval between biopsy and re-excision alters the expression of tissue biomarkers relative to placebo controls in postmenopausal women with newly diagnosed breast cancer.

OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study.

  • Phase I: Patients are randomized to receive either oral LY353381 hydrochloride or oral placebo daily.

Upon completion of phase I, all treatment centers begin phase II of the study.

  • Phase II: Patients are randomized to receive either oral tamoxifen or oral placebo daily.

Treatment in both phases continues for 2-6 weeks (until scheduled lumpectomy or mastectomy) in the absence of disease progression or unacceptable toxicity.

Patients are followed at 1 and 2 weeks after surgery.

PROJECTED ACCRUAL: A minimum of 120 patients (60 per treatment phase) will be accrued for this study within 18 months.
