Alternate Title

Zoledronate in Preventing Bone Loss in Premenopausal Women Receiving Chemotherapy After Surgery For Early Stage Breast Cancer

Basic Trial Information

Objectives

1. Compare the changes in bone mineral density (BMD) and bone turnover that occur in premenopausal women with resected early stage breast cancer during and after 6 months of adjuvant chemotherapy.
2. Determine the factors that predict bone loss during chemotherapy, particularly induction of amenorrhea, type of chemotherapeutic regimen, glucocorticoid exposure, and baseline BMD, in these patients.
3. Determine whether zoledronate prevents bone loss in these patients when given during and after adjuvant chemotherapy.
4. Determine the effect of zoledronate on markers of bone turnover in these patients during and after adjuvant chemotherapy.
5. Determine whether the effect on markers of bone turnover predicts response to zoledronate in these patients.

Entry Criteria

Endocrine therapy

• Not specified

Radiotherapy

• No concurrent radiotherapy

Surgery

• See Disease Characteristics

Other

• At least 1 month since prior calcitonin
• At least 12 months since prior bisphosphonates given for more than 1 month duration
• No concurrent fluoride therapy (10 mg/day or more)

Other

• No T score of less than 2.0 on bone mineral density (BMD)

Expected Enrollment

A total of 120 patients (60 per treatment arm) will be accrued for this study.

Outcomes

Changes in lumbar spine bone mineral density (BMD) at 6 months

Changes in lumbar spine BMD at 12 and 24 months
Total hip and femoral neck BMD at 6, 12, and 24 months
Serum markers of bone turnover (osteocalcin, bone-specific alkaline phosphatase, and cross-linked C-telopeptide of type 1 collagen levels) measured every 6 weeks for 6 months, and at 9 and 12 months
Quality of life as measured by the Short Form-36 instrument at baseline, and at 6 and 12 months
Treatment costs

Outline

This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to estrogen receptor status (positive vs negative), progesterone receptor status (positive vs negative), and adjuvant chemotherapy regimen. Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive zoledronate IV over 15 minutes on day 1.
• Arm II: Patients receive placebo IV over 15 minutes on day 1.

In both arms, treatment repeats every 3 months for up to 4 courses in the absence of disease progression. Patients also receive calcium and cholecalciferol (vitamin D) supplements daily.

Quality of life is assessed at baseline and at 6 and 12 months.

Patients are followed at 1 year.
