Abstract
ICL670 is an orally active representative of a new class of tridentate iron chelator developed for the treatment of blood transfusion-dependent iron overload in chronic anemias. In this randomized, double-blind study, patients with transfusion-dependent beta-thalassemia received single oral doses of ICL670 ranging from 2.5 to 80 mg/kg to investigate its safety, tolerability, and pharmacokinetics and to obtain preliminary information on pharmacodynamic effects. ICL670 was well tolerated, and no safety problems occurred up to 80 mg/kg. A plasma half-life of 11 to 19 hours was found for ICL670, supporting once-daily oral administration. AUC0-24 h and Cmax of ICL670 increased nearly proportionally with the dose. The urinary excretion of ICL670 and its iron complex was less than 0.1% of the dose, and this was in accordance with the expected predominant iron fecal excretion induced by ICL670 (based on preclinical experiments). Notwithstanding, a positive trend toward increased amounts of urinary excreted iron was observed when the AUC0-24 h of ICL670 and the iron complex exceeded specific threshold values at the 40- and 80-mg/kg dose levels.
