Filgotinib

生物活性

Filgotinib (GLPG0634) is an orally-available, selective inhibitor of JAK1 (Janus kinase 1) for the treatment of rheumatoid arthritis and potentially other inflammatory diseases. Filgotinib (GLPG0634) dose-dependently inhibited Th1 and Th2 differentiation and to a lesser extent the differentiation of Th17 cells in vitro. GLPG0634 was well exposed in rodents upon oral dosing, and exposure levels correlated with repression of Mx2 expression in leukocytes. The JAK1 selective inhibitor GLPG0634 (Filgotinib) is a promising novel therapeutic with potential for oral treatment of rheumatoid arthritis and possibly other immune-inflammatory diseases. Filgotinib (GLPG0634) is currently in a Phase 2 study in Crohn's disease.
