Upadacitinib monotherapy demonstrated superior clinical, radiographic, and patient-reported outcomes versus methotrexate in methotrexate-naïve RA patients.This 48-week double-blind active comparator study investigated upadacitinib monotherapy in patients with early RA, who were either methotrexate-naïve, or who had very limited exposure. 947 patients were randomised to once-daily upadacitinib 15 or 30 mg, or weekly methotrexate. Unusually, there were two separate primary endpoints, selected for ...

Safety of synthetic and biological DMARDs: a systematic literature review informing the 2019 update of the EULAR recommendations for the management of rheumatoid arthritis
Annals of the Rheumatic Diseases 2020;79:760-770
This SLR informed the 2019 EULAR taskforce updating recommendations for RA management. Overall, no new safety signals were reported. The known safety profile of bDMARDs was confirmed and extended to tsDMARDS. IL-6i associated lower intestinal perforation has been further confirmed, while VTE and PE concerns in JAKi treatment need further evaluation.Previous updates for the EULAR recommendations on RA pharmacological management were conducted in 2016. In this SLR safety of csDMARDs, tsDMARDs, and...
Pharmacological Treatment of Psoriatic Arthritis: A Systematic Literature Research for the 2019 Update of the EULAR Recommendations for the Management of Psoriatic Arthritis
Annals of the Rheumatic Diseases 2020;79:778-786
This SLR reviewed data on pharmacological treatment of PsA. Findings informed the 2019 EULAR taskforce when updating recommendations for PsA management. Overall, no new safety signals were reported. Encouragingly, LTEs of JAKi did not report any venous thromboembolic events or PEs. Efficacy was demonstrated for a range of bDMARD and tsDMARD therapies in various disease domains. Efficacy varied between PsA manifestations and between therapies. Observational data demonstrated efficacy when switchi...

COVID-19 revisiting inflammatory pathways of arthritis
Nat Rev Rheumatol 2020 doi.org/10.1038/s41584-020-0451-z
This review investigates the potential implications of COVID-19 on the field of rheumatology. Common pathways in COVID-19 and RA have provided rationale for the trial of DMARD therapies in treatment of severe COVID-19 infections. Safety considerations of RA patients undergoing immunomodulatory treatments are reviewed. Recommendations suggest that RA patients should continue DMARD treatment, whereas glucocorticoid use could be deleterious in COVID-19 infection and should be considered carefully, ...

IgA Vasculitis Developed as an Adverse Effect of Tofacitinib Taken for Rheumatoid Arthritis
Intern Med. 2020;59(6):817-821
Nephrotoxicity is a key side effect of NSAIDs and DMARDs used to treat RA, while biologics can reportedly cause proliferative glomerulonephritis or crescentic glomerulonephritis. This report reviews a patient on TOF presenting IgA vasculitis as an adverse effect that fully resolved following termination of TOF.Drug induced IgA vasculitis has been previously described for anti-TNFɑ therapies, but this is the first report with JAK inhibitor therapy. This is a case report of a 67-year old woman wit...

Impact of Janus Kinase Inhibition with Tofacitinib on Fundamental Processes of Bone Healing
Int J Mol Sci 2020;21:865
TOF demonstrated a dose-dependent promotion of human mesenchymal stromal cell (hMSC) recruitment under hypoxia, while inhibiting recruitment under normoxia. TOF also dose-dependently enhances osteogenic differentiation of hMSCs and reduces osteoclast differentiation and activity. As people age, they are more likely to suffer from fractures and delayed bone healing, as well as degenerative joint diseases or osteoporosis. Bone metabolism and fracture healing may be negatively affected by underlyin...

JAK Inhibition Increases Bone Mass in Steady state Conditions and Ameliorates Pathological Bone Loss by Stimulating Osteoblast Function
Sci Transl Med 2020;12(530):pii: eaay4447
JAKi significantly increased osteoblast function but showed no direct effects on osteoclasts.JAK signalling has emerged as an important therapeutic target for inflammatory disease, and the immunomodulation of JAK inhibition is well defined. Less well understood is the influence of this new class of drugs on bone homeostasis. This is important, as cytokine dysregulation triggers bone loss, and periarticular erosions contribute to the pathogenesis of RA. This study investigated the effect of BARI ...

EULAR Recommendations for the Management of Rheumatoid Arthritis – 2019 Update and Consensus Statement on JAKinibs
Ann Rheum Dis. 2020 Jan 22. pii: annrheumdis-2019-216655.
The EULAR recommendations for the management of RA have become increasingly useful in providing rheumatologists, patients, payers and other stakeholders with the evidence-based guidance and views of experts on the optimal use and sequence of pharmaceutical therapies in patients with RA. Over the course of the last decade, the evolution of the treatment landscape has already required two updates. The release of the new addition updates the 2016 recommendations.An international task force consider...

Highlights of 2019
Please click the links below to go to the CSF review of each paper
2019 was another remarkable year in cytokine signalling. We can be optimistic that clinical practice for inflammatory arthritis will continue to improve, with promising long-term safety data supporting the use of established JAK inhibitors; tofacitinib and baricitinib, in addition to exciting phase III clinical data for filgotinib and newly approved upadacitinib. You can find the most notable papers, as selected by CSF Steering Committee Chair Professor Iain McInnes, with links to their respecti...

A systematic review and meta-analysis of infection risk with small molecule JAK inhibitors in rheumatoid arthritis
Rheumatology (Oxford) 2019;58(10):1755–66
Absolute serious infection rates were low. However, across the JAKinibs, the incidence of HZ is higher than expected for the population. While the risk was numerically greatest with BARI, indirect comparisons between the drugs did not demonstrate any significant difference in risk. How JAKinibs increase the risk of HZ reactivation is unclear, but how different JAKs interact in the immune response suggest that there may be differences in safety profiles between JAKinib drugs, underpinned by their...
