    Background: There is still a clinical need for a well-tolerated and safe iron chelator for the treatment of trans-fusional iron overload. We describe the pharmacokinetic properties and safety data after 7 days of dosing of FBS0701, a novel oral, once-daily iron chelator. Design and Methods: This phase 1b dose-escalation study to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of FBS0701, a novel oral iron chelator for the treatment of transfusional iron overload, was conducted in 16 adult patients with iron overloaded consequent to transfusions. FBS0701 was given daily for 7 days at doses up to 32 mg/kg and was well tolerated at all dose levels. Results: Pharmacokinetics showed dose-proportionality. The maxium plasma concentration (Cmax) was reached within 60-90 minutes of dosing and the drug was rapidly distributed at the predicted therapeutic doses. The plasma elimination half-life (t1/2) was approximately 19 hours. There were no serious adverse events associated with the drug. Conclusions: On the basis of these safety and pharmacokinetic data, FBS0701 warrants further clinical evaluation in patients with transfusional iron overload. © 2011 Ferrata Storti Foundation.
