Efficacy and Safety of Deferasirox in β-Thalassemia Major Patients in Iran: A Prospective Study from a Single referral Center in Iran

Introduction: Herein, the results of a prospective study evaluating the efficacy and safety of treatment with deferasirox are studied in iron-overloaded patients with β-thalassemia major during an 18-month trial. Methods: Thirty patients who were previously chelated with deferoxamine with/without deferiprone, and fulfilled the inclusion criteria were recruited. Patients received an initial dose of 10–30 mg/kg/day. Liver and cardiac MRI T2* were evaluated before and after the trial. In addition, serum ferritin level was assessed every 3 months. Primary endpoint was regarded as significant improvement in the severity of liver and cardiac iron overload in severe and moderate cases, in addition to improvement or maintenance of the grade of severity in patients with mild iron overload or normal iron accumulation. Therapy was considered effective if primary endpoint was met in >50%. Results: Liver MRI values improved significantly (P = .002), achieving a 73.33% success rate.
