Fiboflapon sodium (GSK2190915) is a high affinity 5-lipoxygenase-activating protein inhibitor being developed for the treatment of asthma. The compound was originally developed by Amira Pharmaceuticals. Fiboflapon sodium (GSK2190915) exhibits excellent preclinical toxicology and pharmacokinetics in rat and dog. GSK2190915 also demonstrated an extended pharmacodynamic effect in a rodent bronchoalveolar lavage (BAL) model. Oral administration of Fiboflapon sodium (GSK2190915) (1 mg/kg) resulted in sustained inhibition of ex vivo ionophore-challenged whole blood LTB4 biosynthesis with >90% inhibition for up to 12 h and an EC50 of approximately 7 nM. When rat lungs were challenged in vivo with calcium-ionophore, Fiboflapon sodium inhibited LTB4 and cysteinyl leukotriene (CysLT) production with ED50s of 0.12 mg/kg and 0.37 mg/kg, respectively. Fiboflapon sodium is in Phase-II for Asthma (Adjunctive treatment) in Poland, Ukraine, Bulgaria, USA, United Kingdom and Canada (PO).
