Efficacy and Safety of Deferasirox in Non-transfusion Dependent Thalassemia Patients With Iron Overload and a One Year Open-label Extension Study

Summary

CICL670A2209: This study will evaluate the safety and efficacy of deferasirox in non-transfusion dependent thalassemia patients with iron overload. Patients will be treated either with active treatment (deferasirox) or placebo for 12 months (core study phase). Patients who complete the core study phase will be offered to continue their study with the active treatment (deferasirox) in a 12 months extension phase. During the core and extension, the effects of treatment on iron overload in the liver will be evaluated using magnetic resonance imaging (MRI) assessments. CICL670A2209E1: A one-year open-label extension to a randomized, double-blind, placebo-controlled, phase II study to evaluate efficacy and safety of deferasirox in non-transfusion dependent thalassemia patients with iron overload (Thalassa).
