Rheumatology (Oxford). 2021. Epub ahead of print. doi: 10.1093/rheumatology/keab740.

JAK inhibitors are likely to become an important part of the overall treatment paradigm for spondyloarthritis (SpA).Although not fully understood, the pathogenesis of SpA is complex and thought to involve both environmental and genetic factors that together elicit a chronic inflammatory response involving the innate and adaptive immune systems. Several different cytokines, TNF, IL-17A, IL-12/23 and IL-23, which are directly/indirectly affected by JAK molecules, are involved in the pathogenesis o...
Analysis of data over 56 weeks shows that efficacy responses are maintained with upadacitinib 15 mg and 30 mg.Following the publication of 12-week data from the Phase III, randomised double-blind, SELECT-PsA 1 study, earlier this year, McInnes, et al. now report the 56-week efficacy and safety data of upadacitinib 15 mg and 30 mg in patients with PsA and an inadequate response to non-biological therapyEfficacy responses and inhibition of radiographic progression were maintained with upadacitinib...
