Efficacy of Deferasirox for the treatment of iron overload in Chinese thalassaemia major patients: results from a prospective, open-label, multicentre clinical trial

SUMMARY Objective To assess the efficacy and safety of deferasirox in Chinese thalassaemia major (TM) patients Background EPIC (Evaluation of Patients' Iron Chelation with Exjade®) was a large multi‐national study and, notably, the first clinical trial of an iron chelator registered with the Chinese State Food and Drug Administration. Methods Efficacy and safety of deferasirox were compared in Chinese (n = 117) and non‐Chinese (n = 998) TM patients. Deferasirox was initiated at 20 mg kg−1 day−1, with titration increments of 5−10 mg kg−1day−1, based on serum ferritin trends and safety parameters. Results At baseline, Chinese patients were younger than non‐Chinese (mean age 6·8 versus 19·5 years), with higher median serum ferritin (4519 vs 3058 ng mL−1). Over 1 year, mean actual deferasirox dose was similar for Chinese and non‐Chinese patients (24·6 and 24·0 mg kg−1 day−1, respectively); median serum ferritin did not change significantly from baseline in Chinese patients (+340 ng mL−1, P = 0·102) and significantly decreased in non‐Chinese patients (−220 ng mL−1; P
