Immunopharmacology Comments
MAPKAPK5 plays a role in important inflammatory pathways. It was investigated as a novel molecular target for rheumatoid arthritis. Galapagos developed an orally available MAPKAPK5 inhibitor, GLPG0259, which reached Phase 2 clinical trial for methotrexate-refractory RA (NCT01211249). However it quickly became evident that GLPG0259 lacked efficacy in RA patients and the study was terminated [8].
