Summary

RATIONALE: Ibandronate and zoledronate may help relieve some of the symptoms caused by bone metastases. It is not yet know whether ibandronate is more effective than zoledronate in treating bone metastases from breast cancer. PURPOSE: This randomized phase III trial is studying ibandronate to see how well it works compared with zoledronate in treating patients with newly diagnosed bone metastases from breast cancer.

Clinical Details

Official title: Zoledronate Versus Ibandronate Comparative Evaluation: A Randomized Phase III, Open-Label, Multicenter, Parallel Group Clinical Trial to Evaluate and Compare the Efficacy, Safety Profile and Tolerability of Oral Ibandronate Versus Intravenous Zoledronate in the Treatment of Breast Cancer Patients With Bone Metastases

Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Frequency and timing of skeletal-related events (SREs)

Secondary outcome:

Time to first SREs

Proportion of patients with SREs

Pain and analgesic score

Quality of life

Toxicity

Survival

Health resource usage and serum bone marker levels

Detailed description: OBJECTIVES: Primary

- Compare the efficacy, in terms of reducing frequency and timing of skeletal-related

events (SREs), of ibandronate vs zoledronate in patients with newly diagnosed bone metastases secondary to breast cancer. Secondary

- Compare the median time to first SRE in patients treated with these regimens.

- Compare the percentage of patients experiencing a SRE after treatment with these

regimens.

- Compare the number of occult vertebral fractures present in patients at the end of

treatment with these regimens.

- Compare the pain and analgesic scores and quality of life of patients treated with

these regimens.

- Compare the number of patients developing renal dysfunction or hypocalcemia during the

study period.

- Compare the number of patients developing osteonecrosis of the jaw during study

treatment and follow-up.

- Compare the overall survival of these patients at 96 weeks and at 5 years.

- Compare the health-resource usage of patients treated with these regimens.

OUTLINE: This is a randomized, open-label, parallel-group, controlled, multicenter study. Patients are randomized to 1 of 2 treatment arms.

- Arm I: Patients receive zoledronate IV over 15 minutes on day 1. Treatment repeats

every 21* or 28 days for at least 96 weeks (24 or 32 courses) in the absence of disease progression or unacceptable toxicity. NOTE: *Patients who receive concurrent chemotherapy every 3 weeks receive study treatment every 21 days

- Arm II: Patients receive oral ibandronate once daily on days 1-28. Treatment repeats

every 28 days for at least 96 weeks (24 courses) in the absence of disease progression or unacceptable toxicity. Patients with bone pain or hypercalcemia at study entry or those who require IV therapy due to hypercalcemia while on study may receive 1 treatment with ibandronate IV at the discretion of the supervising clinician. Quality of life and pain are assessed at baseline, after every 3 courses, and at completion of study treatment. After completion of study treatment, patients are followed annually for up to 3 years. PROJECTED ACCRUAL: A total of 1,400 patients will be accrued for this study.
