Genetic variants in TNFα, NLRP3, MYD88, and FcRγ genes were associated with a response to TNFi, when assessing several inflammatory diseases together. Al-Sofi et al. conducted a systematic review and meta-analysis on single nucleotide polymorphism (SNP) genetic markers and their response to biologics in psoriasis, PsA, RA, IBD, and across all chronic inflammatory diseases together.

Guselkumab treatment exhibited generally comparable and significant pharmacodynamic effects on IL-23/Th17–associated cytokines across participants with PsA who are biologic-naïve or have TNFi-IR. In coming to this conclusion, investigators assessed and compared immunologic differences and associations with clinical response to guselkumab in participants with active PsA who were biologic-naïve or TNFi-IR.

JAKis differ in structure, which affects their inhibitory concentration for different JAKs.

This review by Taylor, et al. compares the pharmacological profiles of JAKis, including abrocitinib, baricitinib, filgotinib, peficitinib, tofacitinib, and upadacitinib.

Merola et al., reported the effect of interleukin (IL)-17A inhibition with secukinumab on cardiovascular (CV) risk parameters in patients with psoriasis, psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA) over 1 year of treatment. This study evaluated data from 19 secukinumab related clinical trials in phase 3/4 in psoriasis, PsA, and axSpA.

The development of targeted small-molecule therapies such as JAK inhibitors, which have varied selective inhibitory profiles, has enabled a paradigm shift in the treatment of diverse disorders, to the extent that they could ultimately enable either complete withdrawal or avoidance of glucocorticoid use in some autoimmune diseases, and could have the potential to regulate any active factor inhibiting the transition to cure.In this review paper, Tanaka, et al. describe the progress in JAK-targetin...

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...

JAK/STAT pathway and nociceptive cytokine signalling in rheumatoid arthritis and psoriatic arthritis

Crispino N,

Ciccia F.

The JAK/STAT pathway is receiving increasing attention in modulation of nociceptive responses, given its clear role in cytokine signalling. The authors of this review speculate that JAKinibs may have an effect on the modulation of nociception and reduction of pain.Crispino N, et al. review the impact of pain in patients with rheumatic disease and the physiological basis of modulating nociceptive pain. They examine the role of cytokines in the modulation of pain and analyse current clinical JAKin...

The first study to combine in vitro inhibition of cytokine responses in whole blood with clinical pharmacokinetics of individual JAKinibs to model daily cytokine-mediated pharmacodynamic profiles in healthy individuals and patients with RA, has demonstrated that JAKinib potencies depended on cytokine stimulus, pSTAT readout and cell type.Traves and colleagues have observed that JAKinibs have unique, differential effects on specific cytokine signalling pathways, dependent on cytokine stimulus, ST...
