Metastatic bone disease is an important prognostic factor for survival which will in median be close to two years after first diagnosis of osseous metastases. This open-label study will investigate the safety and efficacy of zoledronic acid in patients with breast cancer and minimal residual disease in the bone marrow.

Condition Intervention Phase
Primary Breast Cancer
Drug: Zoledronic acid + Calcium/Vitamin D
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Efficacy and Tolerability of Intravenous Zometa® (Zoledronic Acid) 4 mg in Primary Breast Cancer Patients With Disseminated Tumor Cells in Bone Marrow. A Prospective, Randomized, Parallel Group, Open-label, Clinical Pilot Study.

Primary Outcome Measures:
  • Reduction of detected tumor cells in bone marrow [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Tumor cell detection in bone marrow in comparison to the time point of primary surgery (Baseline). [ Time Frame: 24 months ] [ Designated as safety issue: No ]
  • Bone metastases-free survival [ Time Frame: 24 months ] [ Designated as safety issue: No ]
  • Disease-free survival [ Time Frame: 24 months ] [ Designated as safety issue: No ]
  • Bone mineral density [ Time Frame: at 12 and 24 months ] [ Designated as safety issue: No ]
  • Number and localization of bone metastases [ Time Frame: 24 months ] [ Designated as safety issue: No ]
