|Brief Title ICMJE||Zoledronate in Preventing Bone Loss in Postmenopausal Women Who Are Receiving Letrozole for Stage I, Stage II, or Stage IIIA Breast Cancer|
|Official Title ICMJE||A Randomized, Controlled, Open-Label Trial of Empiric Prophylactic vs. Delayed Use of Zoledronic Acid for Prevention of Bone Loss in Postmenopausal Women With Breast Cancer Initiating Therapy With Letrozole After Tamoxifen|
RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using letrozole may fight breast cancer by lowering the amount of estrogen the body makes. Zoledronate may prevent bone loss in patients who are receiving letrozole. It is not yet known which schedule of zoledronate is more effective in preventing bone loss in patients with breast cancer.
PURPOSE: This randomized phase III trial is studying two different schedules of zoledronate to compare how well they work in preventing bone loss in postmenopausal women who are receiving letrozole for stage I, stage II, or stage IIIA breast cancer.
OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to duration of prior tamoxifen therapy (≤ 2 years vs > 2 years); time since tamoxifen therapy was discontinued (< 1 vs ≥ 1 year); prior adjuvant chemotherapy (yes vs no); and baseline total lumbar spine or femoral neck bone mineral density (BMD) T-score (> -1 standard deviation [SD] vs between -1 to -2 SD). Patients are randomized to 1 of 2 treatment arms.
In both arms, treatment continues for up to 5 years in the absence of disease progression or unacceptable toxicity.
PROJECTED ACCRUAL: A total of 550 patients (275 per treatment arm) will be accrued for this study within 28 months.
