This study reported the long-term efficacy, safety, and tolerability of RZB through 52 weeks of treatment in KEEPsAKE 2. In doing so it demonstrated long-term, durable efficacy of risankizumab in improving symptom control, physical function and quality of life in patients with active PsA who were csDMARD-IR or Bio-IR.

October 2022

Guselkumab (GUS) demonstrates better skin efficacy than most other targeted PsA therapies, including upadacitinib. The objective of this NMA update was to expand the network to include all targeted therapies in PsA on arthritis, skin efficacy and safety, and to include data on GUS patients with an IR to TNFinibs.

September 2022

In the latest study by Curtis, et al. guselkumab treatment regimens improved general HRQoL as measured by the EQ-5D-5L Index and EQ-VAS. In reaching this conclusion investigators aimed to determine the minimal important difference for both instruments and to understand the associations between patient-reported EQ-5D-5L Index and EQ-VAS scores as well as key PsA clinical features.

August 2022

In this study risankizumab treatment resulted in greater improvements in fatigue and pain than placebo. Prior to this finding the study aimed to evaluate the impact of risankizumab on HRQoL and other PROs among patients with active PsA and inadequate response or intolerance to csDMARD-IR in the KEEPsAKE 1 trial.

July 2022

This analysis found that patients with active PsA who receive treatment with guselkumab can achieve robust and sustained low disease activity or remission. In reaching this conclusion investigators sought to evaluate the efficacy of guselkumab for the treatment of active PsA through the use of composite indices.

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...

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...
The abnormal activation of skin immune cells, such as dermal dendritic cells (DDCs) and interleukin (IL)-17-producing γδ T (γδT17) cells, by IL-23 is known to provoke psoriasis-type inflammation. What is less well known is how peripheral nerves regulate cutaneous immune responses. In this study, IL-23-dependent psoriasis-like inflammation was induced in mice to help determine the precise molecular mechanism of neuroimmune communication in the skin. Findings indicate nocic...

This review describes cytokines and the cytokine network in chronic inflammatory diseases such as rheumatoid arthritis (RA). It also discusses how therapies that target cytokines may be feasible and efficacious treatments option for RA. Various targets are considered including blockade of tumour necrosis factor (TNF) and interleukin-1 (IL-1), as well as the targeting of cytokines that play a central role in immune regulation and tissue matrix destruction such as IL-6, IL-15, interferon-gamma (IF...

Cytokines in the pathogenesis of rheumatoid arthritis

Nature Reviews Immunology 2007; 7:429-42

The imbalance between the activity of pro- and anti-inflammatory cytokines favouring induction of autoimmunity, chronic inflammation and joint damage is well known, but how cytokines are organised within a hierarchical regulatory network and which cytokines are the best targets for clinical intervention is uncertain. This review therefore examines the effector function of cytokines in the immunological processes central to the pathogenesis of rheumatoid arthritis (RA). The paper aims to try and ...
