Sélectivité des JAK et implications pour l'inhibition clinique de la signalisation pharmacodynamique des cytokines par le filgotinib, l'upadacitinib, le tofacitinib et le baricitinib

Ann Rheum Dis. 2021 Mar 19:annrheumdis-2020-219012. Epub ahead of print. DOI: 10.1136/annrheumdis-2020-219012

Meng A,

The first study to combine in vitro inhibition of cytokine responses in whole blood with clinical pharmacokinetics of individual JAKinibs to model daily cytokine-mediated pharmacodynamic profiles in healthy individuals and patients with RA, has demonstrated that JAKinib potencies depended on cytokine stimulus, pSTAT readout and cell type.Traves and colleagues have observed that JAKinibs have unique, differential effects on specific cytokine signalling pathways, dependent on cytokine stimulus, ST...

In this study examining the effect of FIL on a panel of biomarkers, FIL down-modulated several key inflammatory mediators of signalling pathways in RA - independent of MTX background therapy. This confirmed the strong network effects of the JAK1 node in autoimmunity, matrix and cartilage degradation, angiogenesis, and leukocyte adhesion and recruitment. Biomarkers key to RA pathophysiology were measured at baseline, Wk4 and Wk12 in FIL 100 mg, FIL 200 mg or PBO treatment groups from two phase 2b...

Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of Filgotinib, a Selective Janus kinase 1 Inhibitor, after Short-term Treatment of Rheumatoid Arthritis: Results of Two randomized Phase IIA Trials

Mazur M,

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 fi...

Preclinical characterization of GLPG0634, a selective inhibitor of JAK1, for the treatment of inflammatory diseases

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...
