Study Description
Brief Summary:
This is a two arm, double-blind randomized study looking at the effect of zoledronate, a bisphosphonate, on the bone mineral density (BMD) of postmenopausal women with breast cancer.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: Zoledronate Phase 2

Detailed Description:
This is a two arm, double-blind randomized study looking at the effect of zoledronate, a bisphosphonate, on the bone mineral density (BMD) of postmenopausal women with breast cancer. An approved bisphosphonate, alendronate, is of benefit in patients with osteoporosis, however, this agent has a roughly 30% incidence of gastrointestinal symptoms and up to 50% of patients may take the drug improperly, compromising absorption and potentially efficacy. Zoledronate is a heterocyclic imidazole third generation bisphosphonate, which is administered intravenously (IV) and has little toxicity. Zoledronate is more potent than alendronate, and because of its route of administration it does not have the problems of poor oral bioavailability and non-compliance.

Arms and Interventions

Arm Intervention/treatment
No Intervention: A
Observation only for 12 months
Active Comparator: B
Zoledronate
Drug: Zoledronate
4 mg IV over 15 minutes administered once every 12 weeks times 4

Outcome Measures

Primary Outcome Measures :
  1. To determine whether zoledronate 4 mg IV every 12 weeks x 4 doses is associated with increases in bone mineral density at the lumbar spine and femoral head [ Time Frame: 3rd bone mineral density assessment ]

Secondary Outcome Measures :
  1. To determine whether zoledronate 4 mg IV every 12 weeks x 4 doses is associated with decreases in rates of bone metastasis, visceral metastasis, and overall mortality [ Time Frame: follow every 6 months for life ]
