Alternative p38 MAPKs Are Essential for Collagen-Induced Arthritis

Arthritis and Rheumatology Vol66, No. 5, May2014 pp 1208-1217

MAPK family proteins are regulatory proteins, affecting processes such as synthesis and release of proinflammatory molecules which contribute to the pathogenesis of RA. In particular, the p38 MAPK protein family is central to proinflammatory cytokine production. There are four member of the p38 group; p38α, p38β, p38γ and p38δ. This study sought to evaluate p38γ and p38δ deficiency in mice CIA model. In p38γ-/- or p38δ-/- mice, the percentage of mic...

Oral administration of GLPG0259, an inhibitor of MAPKAPK5, a new target for the treatment of rheumatoid arthritis: a phase II, randomised, double-blind, placebo-controlled, multicentre trial

Ann Rheum Dis. 2013 May; 72(5):741–4

This phase2 trial assessed the efficacy of GLPG0259, a first-in-class ATP-competitive inhibitor of MAPKAPK5. The trail involved 31 patients with active RA and an inadequate response MTX. Patients received either 50 mg/day GLPG0259 with MTX or a placebo with MTX (patients randomised 2:1) for 12 weeks with the primary efficacy variable being ACR 20 response at week 12. Analysis showed that 5 patients (26.3%) in the GLPG0259 group and 3 patients (27.3%) in the placebo group achieved ACR 20 at 12 we...
