RINVOQ (upadacitinib) is indicated for the treatment of adults with moderately to severely active rheumatoid arthritis (RA) who have had an inadequate response or intolerance to methotrexate (MTX). RINVOQ may be used as monotherapy or in combination with MTX or other nonbiologic disease-modifying antirheumatic drugs (DMARDs).
RINVOQ's mechanism of action†
Upadacitinib modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs which modulate intracellular activity including gene expression. JAK enzymes transmit cytokine signaling through their pairing (e.g., JAK1/JAK2, JAK1/JAK3, JAK1/TYK2, JAK2/JAK2, JAK2/TYK2).
In cell-free isolated enzyme assays, RINVOQ had greater inhibitory potency at JAK1 relative to JAK2, JAK3 and TYK2. In human cellular assays, RINVOQ inhibited cytokine-induced STAT phosphorylation mediated by JAK1 and JAK1/JAK3 more potently than JAK2/JAK2 mediated STAT phosphorylation.
