This analysis aimed to report the safety profile of ixekizumab for the PsA SPIRIT programme. The overall safety profile and tolerability of ixekizumab are consistent with the previously known safety profile in patients with PsA.

D'Agostino, et al. aimed to evaluate whether treatment with secukinumab inhibits synovitis in patients with active PsA, as measured by PDUS. They found that secukinumab rapidly and significantly decreased synovitis, indicating a direct effect of IL-17 inhibition on the synovium in patients with PsA.

Merola and colleagues demonstrated a rapid and sustained reduction in hsCRP and the neutrophil-lymphocyte ratio (NLR) in patients with IMIDs with a high systemic inflammatory burden treated with secukinumab.

Treatment of axial spondyloarthritis: an update

Nat Rev Rheumatol. 18, 205–216 (2022) 2022 doi: 10.1038/s41584-022-00761-z

In this review Danve and Deodhar report an update on modern axSpa treatment. They found that in the past two decades substantial progress in the diagnosis and management of axSpA has been witnessed. Whilst ASAS classification criteria have enabled earlier diagnosis the increased availability of novel therapies, evolving drug safety data and novel clinical trials have allowed clinicians to rethink the placement and timing of drugs in disease management.

The most common immune system-related AEs in patients treated with IL-17 inhibitors are mucosal and opportunistic infections.

Interleukin (IL)-17 inhibitors are a series of biological drugs used to treat a number of conditions, including ankylosing spondylitis, a disease characterised by immune system dysregulation and joint inflammation. Azadeh, et al. aimed to assess the risk of immune system-related AEs due to targeting IL-17 or IL-17R.

Predefined analysis of FUTURE 5, the largest Phase 3 randomised trial of secukinumab in patients with PsA to date, demonstrates that secukinumab results in early, statistically significant, clinically meaningful, sustained improvements in PROs across all doses, compared with placebo.The fully human anti-interleukin 17A monoclonal antibody, secukinumab has shown clinical and radiographical efficacy in patients with PsA, yet the clinical significance of improvements across a wide variety of PROs r...

A review of JAK-STAT signalling in the pathogenesis of spondyloarthritis and the role of JAK inhibition

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...

Bayesian network meta-analysis of randomised controlled trials (RCTs) highlights the effectiveness of secukinumab, ixekizumab, and tofacitinib in patients with psoriatic arthritis (PsA) and an inadequate response to tumour necrosis factor inhibitors (TNFi).There is a current need for therapies with alternative mechanisms of actions to DMARDs and TNFi, for the significant proportion of patients with PsA who insufficiently respond to these therapies. While RCTs for therapies such as secukinumab a...

Pathogenetic Insights from the Treatment of Rheumatoid Arthritis

Lancet 2017;389:2328–37 DOI 10.1016/S0140-6736(17)31472-1

This review paper examines the understanding gained from looking at the effects of specific immune interventions in the treatment of RA.The introduction of novel IL-6 agents has provided the ideal opportunity to explore the distinct effect of cytokine inhibition, as opposed to receptor inhibition, at the molecular level. Mechanistic insights into TNF could also be obtained in the future with advanced molecular and informatics approaches, and future biopsy studies will be important to explore the...

Psoriatic arthritis (PsA) is a chronic inflammatory arthritis associated with psoriasis (Ps) and characterised by synovitis and progressive destruction of articular cartilage and bone. Recently developed agents for PsA target IL12p40, IL-6 and IL-17, several of which signal through the JAK family of receptor-associated tyrosine kinases. Tofacitinib is a drug of the JAK inhibitor class and is currently approved for the treatment of RA in 27 countries. This study evaluated the effect of tofacitini...
