Brief summary
The evaluation of efficacy is performed by laboratory monitoring of bone density and resorption markers and clinical monitoring of bone density improvement. This is a prospective, randomized, parallel group, single blind study of one year treatment with zoledronic acid every 6 months as compared to one year treatment with zoledronic acid every 3 months and to placebo every 3 months in patients with hemoglobin syndromes and risk of skeletal complications.
