Abstract
Deferasirox is a novel once-daily, oral iron chelator. The aim of this study was to evaluate the long-term efficacy and tolerability of deferasirox in Taiwanese patients with transfusion-dependent β-thalassemia who have been treated with deferasirox for 7?years. Taiwanese patients aged ?2?years with transfusion-dependent β-thalassemia whose serum ferritin levels were ?1000?ng/mL and had started deferasirox treatment since December 2005 at the National Taiwan University Hospital were enrolled. Sixty patients were recruited for analysis, and 11 (18.3?%) patients discontinued deferasirox during the study. In the 42 patients included in the efficacy analysis, the mean serum ferritin levels decreased significantly by 2566?ng/mL after 7?years of treatment (P < 0.001). Forty-one of these patients received a cardiac T2* evaluation after 3?years of deferasirox treatment, and the mean cardiac T2* value increased significantly from 30.6 ± 16.6 to 45.9 ± 22.6?ms after 7?years of deferasirox treatment (P < 0.001). Deferasirox-related adverse events assessed by investigators were reported in 46 (76.7?%) patients. The most common adverse events related to deferasirox were skin rashes (n = 29, 48.3?%), followed by abdominal pain (n = 23, 38.3?%) and diarrhea (n = 16, 26.7?%). Most adverse events were manageable. This study demonstrated that long-term treatment with deferasirox was effective in improving iron overload, including cardiac iron overload, in patients with transfusion-dependent β-thalassemia. Deferasirox was well tolerated; however, the incidences of common adverse events related to deferasirox appeared higher in our Taiwanese patients than other studies. ? 2015, The Author(s).
