Evaluate the Relationship of Bone Remodeling Markers for Skeletal Complications in Metastatic Breast Cancer Patients
A Phase IV, Multi-center, Open Label, Single Arm Clinical Trial to Evaluate the Relationship of Bone Remodeling Markers for Skeletal Complications in Metastatic Breast Cancer Patients
to evaluate whether bone marker can provide the valuable predictor of skeletal complications and whether regular assessing of NTX(N-telopeptide of type I collagen) and osteocalcin can be useful in advanced breast cancer patients with bone metastasis receiving zoledronic acid.

to evaluate the efficacy and safety of zoledronic acid by measuring changes in bone turnover markers

  • the incidence of skeletal-related events
  • time to skeletal-related events
  • time to bone metastases progression
  • overall survival
  • the incidence of each adverse event including osteonecrosis
Interventional
Phase 4
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Metastatic Breast Cancer
Drug: zoledronic acid
Intravenous zoledronic acid 4mg over a minimum of 15 minutes in at least 100mls of calcium free infusion solution (0.9% sodium chloride or 5% glucose solution) every 4 weeks.
Other Name: ZOMETA
Experimental: Zoledronic acid
Patients with advanced breast cancer with radiographic confirmation of bone metastases. This arm will be receiving zoledronic acid administration. The primary endpoint is to find the correlation between bone turnover markers and the frequency of skeletal-related-events for one year. Skeletal related events are defined as pathologic fractures, the need for radiation therapy, orthopaedic surgery, hypercalcemia of malignancy and spinal cord compression. A total of 237 patients will be included.
Intervention: Drug: zoledronic acid
