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...

JAKinibs have been linked with an increased risk of HZ in patients with RA. To this end, Winthrop, et al. evaluated data from six Phase III clinical trials to determine the incidence of HZ in the upadacitinib (UPA)-treated patients with RA and identify potential risk factors for the development of HZ in these patients.Analysis of data provides further support for the need for continued vigilance and monitoring for signs of herpes zoster (HZ) in patients receiving UPA, particularly in Asian popul...

In a real-world setting, tofacitinib and baricitinib have comparable continuing efficacies and safety profiles in patients with RA.It is important to determine the differences and similarities of JAK inhibitors in a real-world setting so that the optimal agent can be administered. However, until now, no published data of a direct comparison among these agents in RA have been available. With this in mind, Iwamoto, et al. compared the efficacy and safety of tofacitinib with those of baricitinib by...

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. explored...

Upadacitinib efficacy proves to be greater than placebo, and non-inferior to adalimumab, in treating patients with psoriatic arthritis (PsA). Already approved for the treatment of rheumatoid arthritis, McInnes, et al. studied oral upadacitinib at a dose of 15 mg or 30 mg, alongside placebo or adalimumab, in this 24-week, Phase III trial, in over 1700 patients with PsA. At the primary endpoint (Week 12), ACR20 response was greater with upadacitinib than placebo, and non-inferior to adalimumab; wi...

A population-based cohort study of 87,653 RA patients has found no evidence for an increased risk of venous thromboembolism (VTE) for tofacitinib, versus TNFis, in patients with RA.The introduction of JAKinibs, almost a decade ago, has provided an important oral option for the treatment of RA. However, in recent years, a safety concern, relating to incidence of VTE after treatment, has emerged. Consequently, both the US and European regulatory authorities now recommend caution for use of tofacit...

A long-term extension study of filgotinib showed consistent safety profile and sustained efficacy with the drug for up to four years. The DARWIN 3 study, for patients who previously completed either the 24-week DARWIN 1 study (filgotinib + MTX) or the DARWIN 2 study (filgotinib monotherapy), enrolled 739 patients with RA. At the time of analysis, 440 patients had received four years or more of filgotinib. Exposure-adjusted incidence rate per 100 patient-years-of-exposure for TEAEs was 24.6 in th...

This analysis provides evidence that immune cell signalling pathways are important in RA. There were consistent differences between RA patients and healthy controls in IFNα, IL-6, IL-10 and GM-CSF+ IL-2 induced JAK/STAT signalling in multiple immune cell subsets.We know that RA is characterised by dysregulation of immune responses, but the exact cause is unknown. Recently, single-cell transcriptomics and mass cytometry confirmed the critical role of activated immune cells and fibroblasts, increa...

MRI studies have shown that BARI reduces joint inflammation and damage in patients with moderate-to-severe active RA. This review summarises the effects of BARI on structural joint damage progression and the mechanisms underlying these effects, using MRI data from across the clinical trial program. Early preclinical animal models showed a significant reduction in joint inflammation, ankle width, and bone resorption. Efficacy and safety of BARI have been confirmed in an extensive programme, inclu...

JAKi are approved in various immune-mediated inflammatory diseases. With five JAKi now licensed, this paper reviews key points to consider in their use to assist clinicians, patients, and other stakeholders once the decision is made to commence JAKi.The consensus was developed by a Steering Committee and an expanded Task Force using EULAR standard operating procedures. The committee included patients as well as experts in rheumatology, gastroenterology, haematology, dermatology, and infectious d...
