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 ...

Fifty-six-week data suggest that upadacitinib could be a favourable long-term treatment option in patients with PsA who are refractory to biologic therapy. As the need for additional therapeutic agents that can effectively control disease activity continues, new data from a 56-week analysis of the oral reversible JAK1 inhibitor, upadacitinib, currently under investigation for the treatment of PsA, shows that efficacy of the drug is maintained over the duration of this study. Mease, et al. expl...

In this trial of patients with active PsA who had inadequate response or intolerance to at least one biologic DMARD, upadacitinib 15 mg and 30 mg was more effective than placebo over 24 weeks in improving signs and symptoms of PsA. Despite the availability of bDMARDs in PsA, only a small proportion of patients achieve the recommended target of minimal disease activity; as such, additional treatment options are needed. Upadacitinib is under evaluation for PsA. This paper reports the 24-week data...
