Deferasirox is a once-daily oral iron chelator with established dose-dependent efficacy in both adult and pediatric patients with transfusional iron overload. The clinical development program has demonstrated the efficacy of deferasirox for up to 4.5 years of treatment in patients with various underlying anemias, including beta-thalassemia, myelodysplastic syndromes, sickle cell disease, aplastic anemia, and other rare anemias. In addition to reducing key indicators of total body iron levels (serum ferritin, liver iron concentration, and toxic labile plasma iron), deferasirox has also demonstrated the ability to remove cardiac iron and prevent future cardiac iron accumulation. Emerging long-term data confirm the tolerability profile of deferasirox, and data on patient compliance render deferasirox a suitable therapeutic option for patients with chronic conditions requiring ongoing iron chelation therapy. Data continue to accumulate in a wide range of patient groups, including those with non-transfusion-dependent anemias such as hereditary hemochromatosis.
地拉罗司是一种每日一次的口服铁螯合剂,在患有输血性铁过载的成人和儿童患者中具有已确立的剂量依赖性疗效。临床开发项目已证明,地拉罗司对包括β地中海贫血、骨髓增生异常综合征、镰状细胞病、再生障碍性贫血和其他罕见贫血在内的各种潜在贫血患者进行长达4.5年的治疗均有效。除了降低全身铁水平的关键指标(血清铁蛋白、肝脏铁浓度和毒性不稳定血浆铁)外,地拉罗司还证明了清除心脏铁并防止未来心脏铁蓄积的能力。新出现的长期数据证实了地拉罗司的耐受性,关于患者依从性的数据使地拉罗司成为需要持续铁螯合治疗的慢性病患者的合适治疗选择。在包括遗传性血色素沉着症等非输血依赖性贫血患者在内的广泛患者群体中,数据仍在不断积累。
