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...

Integrated analysis evaluates the safety of filgotinib among patients with RA treated for a median of 1.6 years.Winthrop, et al. analysed data from seven trials, including long-term extension studies, and found that rates of TEAEs, grade ≥3 TEAEs, serious TEAEs and TEAEs leading to study drug discontinuation were comparable for filgotinib and placebo. In addition, analysis of AEs of special interest showed a generally similar incidence for filgotinib 200 mg and 100 mg....
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...

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...
Analysis of data from the highest level of patient exposure to baricitinib across the spectrum of the RA population demonstrates that baricitinib maintained a similar safety profile to earlier analyses, with no new safety signals identified.Using integrated data from nine randomised controlled trials, Taylor, et al. assessed the safety of baricitinib 2 mg and 4 mg once-daily. Analysis of data from 3770 patients (median 4.6 years, up to 9.3 years) with active RA showed that baricitinib maintained...

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...
Tofacitinib could induce Hepatitis B virus (HBV) reactivation in RA patients.With previous studies having already demonstrated that RA patients using biologic agents, might experience HBV reactivation leading to acute hepatitis, hyperbilirubinemia, and death, Wang, et al. aimed to investigate HBV reactivation in patients with RA receiving tofacitinib. They found that Hepatitis B surface antigen positive patients receiving tofacitinib have a high incidence rate of HBV reactivation, which could be...
