Risk of venous thromboembolism associated with tofacitinib in patients with rheumatoid arthritis: a population-based cohort study

Rheumatology (Oxford). 2021 Mar 22:keab294. Epub ahead of print. DOI: 10.1093/rheumatology/keab294

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...

Comparative effectiveness of first-line tumour necrosis factor inhibitor versus non-tumour necrosis factor inhibitor biologics and targeted synthetic agents in patients with rheumatoid arthritis: results from a large US registry study

Ann Rheum Dis 2021;80:96–102.

RA treatment guidelines recommend a treat-to-target approach guided by disease stage and treatment history, yet the optimal sequence of different treatment modalities has not been established. Data from Corrona – were used to evaluate the comparative effectiveness of TNFi versus non-TNFi bDMARDs and tsDMARDs as first-line treatment following csDMARD failure. Results support RA guidelines recommending individualised care based on clinical judgement and consideration of patient preference.The stud...

Switching between Janus kinase inhibitor upadacitinib and adalimumab following insufficient response: efficacy and safety in patients with rheumatoid arthritis

Ann Rheum Dis 2020; doi:10.1136/annrheumdis-2020-21841220

Both ACR and EULAR recommend adding a biologic or targeted synthetic DMARD in patients who do not achieve treatment goals at follow-up. Findings indicated that an immediate switch in mechanism of action (from JAKi to TNFi and vice versa) following treat-to-target principles is feasible with minimal risk of flare regardless of whether patients are switched due to non-response or incomplete-response.SELECT-COMPARE followed treat-to-target principles to examine the efficacy of switching in two pati...

Age-Based (<65 vs ≥65 years) Incidence of Infections and Serious Infections with Tofacitinib Versus Biological DMARDs in Rheumatoid Arthritis Clinical Trials and the US Corrona RA Registry

Ann Rheum Dis 2020; DOI: 10.1136/annrheumdis-2020-218992

Reports from clinical trials and the US Corrona RA registry showed that serious infection event (SIE) incidence was higher in older versus younger patients with RA receiving 10 mg BID of TOF and ADA, however, SIE risk was similar between age groups with TOF 5 mg BID and ADA.Data were collected from Phase II–IV tofacitinib studies, and the US Corrona RA registry. The clinical data set evaluated patients receiving TOF 5 and 10 mg BID versus TNFi (ADA/ETN) in RA patients aged ≥50 years. The EMA rec...

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...

Drug retention of 7 biologics and tofacitinib in biologics-naïve and biologics-switched patients with rheumatoid arthritis: the ANSWER cohort study

Arthritis Res Ther 2020;22:142

This paper is based upon a long-term cohort study, namely the ANSWER cohort, an observational multi-centre registry of RA patients in the Kansai district of Japan. Analyses demonstrate a difference in observed drug retention between bDMARDs-naïve and bDMARDs-switched patients. 7 bDMARD treatments were compared in patients with no prior exposure to biologics, with abatacept showing the greatest retention rate. In patients that had switched between these same bDMARDs or to tofacitinib throughout t...

Comparative effectiveness of antitumour necrosis factor agents, biologics with an alternative mode of action and tofacitinib in an observational cohort of patients with rheumatoid arthritis in Switzerland

RMD Open 2020;6:e001174 doi:10.1136/rmdopen-2020-001174

This nested cohort study found that, in Switzerland, there was a generally limited overall drug maintenance for b/tsDMARD options in RA. Using data from SCQM-RA – a prospective longitudinal registry, overall maintenance (drug survival) was calculated for TNFi, bDMARD-OMA or JAKi in patients with RA.After adjusting for potential confounding factors, there was a higher hazard of drug discontinuation with TNFi compared with tofacitinib; no significant difference was observed between non-TNF bDMARDs...

Fenebrutinib Versus Placebo or Adalimumab in Rheumatoid Arthritis: A Randomized, Double-Blind, Phase II Trial (ANDES Study)

Arthritis Rheumatol. 2020 Sep; 72(9): 1435–1446.

In this randomised phase II trial with MTX treatment-refractory RA patients, greater efficacy was observed with fenebrutinib 150 mg once daily or 200 mg twice daily compared to placebo, while response rates were numerically similar to those observed with adalimumab. BTK inhibitors have demonstrated clinical efficacy in B cell malignancies and multiple sclerosis, although there is limited clinical evidence of its efficacy in RA. Fenebrutinib (FEN) an orally active and selective non-covalent inhib...

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...
