A Phase 3 study assesses the efficacy and safety of tofacitinib in adults with active AS.Deodhar, et al. found that ASAS20 and ASAS40 response rate significantly increased with tofacitinib 5 mg BID versus placebo at Week 16, with improvements maintained to Week 48.There were no new safety signals detected over the course of the study....

Highlights of 2021

I’m sure we’d all hoped that this year would be a return to normal but, in the midst of the challenges we’ve faced with COVID-19, the rheumatology community has continued to deliver excellent publications, and we’ve covered many of these on the CSF. Here are my highlights from 2021's publications: Points to Consider for the Treatment of Immune-Mediated Inflammatory Diseases With Janus Kinase Inhibitors: A Co...

Pivotal trial data show that tofacitinib is an effective treatment in patients with polyarticular course juvenile idiopathic arthritis (pJIA).New oral therapies are particularly relevant for children and adolescents, who might prefer to avoid injections. To this end, Ruperto, et al. assessed the efficacy and safety of tofacitinib versus placebo in patients with pJIA (N=225). They observed a JIA flare rate at Week 44 of 29% and 53% for tofacitinib and placebo, respectively. Safety results were si...

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...
Analysis of data over 56 weeks shows that efficacy responses are maintained with upadacitinib 15 mg and 30 mg.Following the publication of 12-week data from the Phase III, randomised double-blind, SELECT-PsA 1 study, earlier this year, McInnes, et al. now report the 56-week efficacy and safety data of upadacitinib 15 mg and 30 mg in patients with PsA and an inadequate response to non-biological therapyEfficacy responses and inhibition of radiographic progression were maintained with upadacitinib...

Oral baricitinib maintained lower levels of radiographic progression than initial csDMARD or placebo through 5 years in patients with active RA.It is well known that persistent joint inflammation in RA can lead to irreversible structural damage that impacts on patient physical function and quality-of-life. To this end, van der Heijde, et al. evaluated the effect of baricitinib on inhibiting radiographic progression of structural joint damage over 5 years in patients with active RA. Results from ...
Propensity score-based inverse probability of treatment weighting shows that efficacy may differ between tofacitinib and baricitinib. Miyazaki, et al. compared the efficacy and safety of the two JAK inhibitors in real-world clinical practice, after reduction to a minimum of the selection bias, using propensity score-based inverse probability of treatment weighting, and adjustment for confounding patient characteristics. They found that tofacitinib may be less effective in patients resistant to m...

Post hoc analysis of the phase III FINCH study shows that filgotinib may be an alternative treatment option for patients with RA who have poor prognostic factors (PPFs), especially those not responding to standard treatment such as methotrexate (MTX).PPFs are associated with severe disease and risk for disease progression in patients with RA. Consequently, the 2019 EULAR management guidelines for RA recommend early treatment escalation for patients with PPFs who have inadequate response to first...
Real-world evidence suggests that monotherapy and combination therapy tofacitinib is an effective intervention in RA with persistence and effectiveness comparable to bDMARDs. Despite recommendations from EULAR that bDMARDs and tsDMARDs be used in combination with csDMARDs for the treatment of RA, it is estimated that up to a third of patients take their medication as monotherapy.This post hoc analysis of data from the Australian OPAL study by Bird, et al. aimed to describe the real-world effecti...

August 2021

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...
