Brief Title ICMJE	S0307 Phase III Trial of Bisphosphonates as Adjuvant Therapy for Primary Breast Cancer.
Official Title ICMJE	Phase III Trial of Bisphosphonates as Adjuvant Therapy for Primary Breast Cancer
Brief Summary	RATIONALE: Zoledronate, clodronate, or ibandronate may delay or prevent bone metastases in patients with nonmetastatic breast cancer. It is not yet known whether zoledronate is more effective than clodronate or ibandronate in treating breast cancer. PURPOSE: This randomized phase III trial is studying zoledronate to see how well it works compared to clodronate or ibandronate in treating women who have undergone surgery for stage I, stage II, or stage III breast cancer.
Detailed Description	OBJECTIVES: Compare disease-free survival and overall survival of women with resected primary stage I-III adenocarcinoma of the breast treated with adjuvant zoledronate vs clodronate vs ibandronate.; Compare the distributions of sites of first disease recurrence in patients treated with these drugs.; Compare adverse events in patients treated with these drugs.; Correlate parathyroid hormone related protein status and N-telopeptide levels at baseline with disease-free survival and sites of first recurrence in patients treated with these drugs.; Investigate whether there is an association between inherited germ-line single nucleotide polymorphisms (SNP, rs2297480) in farnesyl diphosphate synthase (FDPS) and the adverse event of acute phase reactions in these patients. OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 3 treatment arms.; Arm I: Patients receive zoledronate IV over 15 minutes once a month for 6 months and then once every 3 months for 2.5 years.; Arm II: Patients receive oral clodronate once daily for 35 months.; Arm III: Patients receive oral ibandronate once daily for 35 months. Treatment in all arms continues in the absence of disease recurrence or unacceptable toxicity. After completion of study treatment, patients are followed every 6 months until disease recurrence and then annually for up to 10 years. PROJECTED ACCRUAL: A total of 5,400 will be accrued for this study.
