Study Details

Study Description

Brief Summary

A 1-year randomized Phase III core trial (NCT00061750) using deferoxamine as the comparator was conducted to investigate the efficacy of deferasirox in regularly transfused patients with β-thalassemia 2 years of age and older. Patients who successfully completed this main trial may continue in this extension trial to receive chelation therapy with deferasirox for an additional 4 years.

The objective of this study is to assess the efficacy and long-term safety of deferasirox in regularly transfused patients with β-thalassemia 2 years of age and older.

Arm/Group Title Crossover ICL670
Arm/Group Description Participants treated with Deferoxamine (DFO) during the core study and crossed over to receive Deferasirox (ICL670) orally once a day during the extension study. Dosage based on body weight. Participants treated with Deferasirox (ICL670) orally once a day during the core study and continued this treatment in the extension study. Dosage based on body weight.
