Drug: Placebo
Placebo |
- To describe the percent change in the lumbar spine (L1 to L4) BMD, as measured by dual energy X-ray absorptiometry, at 12 months in patients with beta-thalassemia major undergoing allogenic BMT randomized to zoledronic acid versus placebo. [ Time Frame: 1 year ]
- To describe the percent change in total hip BMD at 12 months in the two study arms. [ Time Frame: 1 year ]
- To compare the changes in bone turn over markers at 3, 6, and 12 months in the two treatment arms. [ Time Frame: 1 year ]
- To describe the incidence rate of all clinical fractures at 1 year in the two study arms. [ Time Frame: 1 year ]
- To describe the general safety of zoledronic acid. [ Time Frame: 1 year ]
- To describe the percent change in lumbar spine (L1 to L4) BMD and total hip BMD at 6 months when available. [ Time Frame: 1 year ]
