In two 4-week exploratory Phase 2a trials in MTX-inadequate responder (IR) patients with RA, the highly selective JAK1 inhibitor filgotinib met the primary endpoint of ACR20 at Week 4, showing greater response than placebo. Study 1, a proof-of-concept study, included 127 patients randomised to placebo, filgotinib 100 mg BID or filgotinib 200 mg QD. Study 2, was a dose-ranging study and included 91 patients randomised to placebo, filgotinib 30 mg QD, filgotinib 75 mg QD, filgotinib 150 mg QD or ...

Journal of Immunology 2013;191:3568–77

JAK inhibitors have been identified as having a critical role as therapeutic targets for autoimmune, inflammatory and oncological diseases. GLPG0634 was shown to inhibit JAK1/JAK2 but with a much greater effect on JAK1, a critical pathway in the signal transduction of many inflammatory cytokines. In rodent testing, GLPG0634 showed significant dose-dependent reduction in disease progression in collagen-induced arthritis models, with comparable efficacy to etanercept. An orally bioavailable treatm...
