ABSTRACT
<p><b>OBJECTIVE</b>To explore the efficacy and safety of deferasirox in aplastic anemia (AA)patients with iron overload.</p><p><b>METHODS</b>A single arm, multi- center, prospective, open- label study was conducted to evaluate absolute change in serum ferritin (SF)from baseline to 12 months of deferasirox administration, initially at a dose of 20 mg·kg(-1)·d(-1), and the safety in 64 AA patients with iron overload.</p><p><b>RESULTS</b>All patients started their deferasirox treatment with a daily dose of 20 mg · kg(-1) ·d(-1). The mean actual dose was (18.6±3.60) mg · kg(-1)·d(-1). The median SF decreased from 4 924 (2 718- 6 765)μg/L at baseline (n=64) to 3 036 (1 474- 5 551)μg/L at 12 months (n=23) with the percentage change from baseline as 38%. A median SF decrease of 651 (126-2 125)μg/L was observed at the end of study in 23 patients who completed 12 months' treatment, the median SF level decreased by 1 167(580-4 806)μg/L [5 271(3 420-8 278)μg/L at baseline; 3 036(1 474-5 551)μg/L after 12 months' treatment; the percentage change from baseline as 42% ] after 12 months of deferasirox treatment. The most common adverse events (AEs) were increased serum creatinine levels (40.98%), gastrointestinal discomfort (40.98%), elevated liver transaminase (ALT 21.31%; AST 13.11%)and proteinuria (24.59%). The increased serum creatinine levels were reversible and non-progressive. Of 38 patients with concomitant cyclosporine use, 12(31.8%)patients had two consecutive values >ULN, 10(26.3%)patients had two consecutive values >1.33 baseline values, but only 1(2.6%)patient's serum creatinine increased more than 1.33 baseline values and exceeded ULN. For both AST and ALT, no patients experienced two post- baseline values >5 ×ULN or >10 × ULN during the whole study. In AA patients with low baseline PLT count (less than 50 × 10(9)/L), there was no decrease for median PLT level during 12 months' treatment period.</p><p><b>CONCLUSIONS</b>AA patients with iron overload could achieve satisfactory efficacy of iron chelation by deferasirox treatment. The drug was well tolerated with a clinically manageable safety profile and no major adverse events.</p>
