Mechanism of Action

Targets/IC₅₀/Ki	JAK1 (Cell-free assay) 10 nM JAK2 (Cell-free assay) 28 nM TYK2 (Cell-free assay) 116 nM JAK3 (Cell-free assay) 810 nM
In vitro	Filgotinib (GLPG0634) inhibits IL-2- and IL-4-induced JAK1/JAK3/γc signaling and IFN-αB2-induced JAK1/TYK2 type II receptor signaling with IC50 values ranging from 150 to 760 nM in cell lines. It shows higher selectivity for JAK/STAT signaling involving JAK1 than JAK2 kinase in a cellular context. Besides, this compound also inhibits the differentiation of Th1, Th2, and Th17 cells.
In vivo	Following oral administration, the absolute bioavailability of filgotinib (GLPG0634) is moderate in rats (45%) and high in mice (∼100%). This compound (30 mg/kg daily (Rats); 50 mg/kg twice daily (Mice)) dose-dependently reduces inflammation, cartilage, and bone degradation in the CIA model in rats and mice. In DSS-treated mice, it demonstrates that inhibition of JAK1 is sufficient for achieving strong efficacy in pre-clinical mouse model, correlated to the inhibition of STAT3 phosphorylation in the inflamed colon.
