During the approval process of Totect® (trade name Savene® in the European market) - TopoTarget made a commitment to complete and submit a post-marketing population pharmacokinetic analysis to the FDA. A clinical phase IV study was conducted to examine the pharmacokinetics of a 3-day dosing regimen of Totect® efficacy in patients suffering from anthracycline extravasation. The clinical results confirmed TopoTarget's theoretical model and thus ruled out Totect® accumulation during the recommended 3-day treatment regime. The results were accepted by the FDA and TopoTarget has now fulfilled its commitment. Today's news does not change TopoTarget's full-year financial guidance for 2008.
