After JAK Inhibitor Failure: To Cycle Or To Switch, That Is The Question – Data From The JAK-Pot Collaboration of Registries
Ann Rheum Dis. 2022. doi: 10.1136/ard-2022-222835
Data from the JAK-pot collaboration of registries show that cycling JAKinibs and switching to a bDMARD appear to have similar effectiveness, after failing the first JAKinib.
Comparison of drug retention of TNF inhibitors, other biologics and JAK inhibitors in RA patients who discontinued JAK inhibitor therapy
Rheumatology (Oxford) 2022 doi: 10.1093/rheumatology/keac285
Real-world population-based study shows that a switch to a second JAKinib results in a higher drug retention, as compared to switching to a TNFi, in patients with RA who discontinue original JAKinib therapy.
Effect of dose adjustments on the efficacy and safety of tofacitinib in patients with rheumatoid arthritis: a post hoc analysis of an open-label, long-term extension study (ORAL Sequel)
Clin Rheumatol. 2022 Jan 1. Epub ahead of print doi: 10.1007/s10067-021-05908-zPost-hoc analysis shows that dosing up from tofacitinib 5 to 10 mg BID is associated with improved efficacy for up to 12 months, versus staying on 5 mg BID, and dosing down from 10 to 5 mg BID is not generally associated with a significant loss of efficacy.Although clinical trials have generally shown no significant differences, in terms of efficacy and safety, when switching tofacitinib dose up or down, these per-protocol switches are not directly informative for clinical decision-making in dai...
The JAK/STAT Pathway: A Focus on Pain in Rheumatoid Arthritis
Semin Arthritis Rheum. 2021 Feb;51(1):278-284Many cytokines associated with RA pathogenesis and pain are affected directly or indirectly by the JAK/STAT pathway, therapeutic targeting may offer promise. Having better understanding of these mechanisms can help clinicians make treatment decisions that optimise the control of inflammation and pain. However, pain in patients with RA is complex and involves multiple driving mechanisms that may differentially occur over time in different people. Although one known constant is that nociceptive ac...
Highlights of 2020
Please click the links below to go to the CSF review of each paper2020 unfolded apace, dominated by COVID-19 - we have all had to adapt in our practice and in our knowledge base. Amid this there have continued to be a constant flow of publications and science in cytokine signaling, and as in previous years as we come the end of 2020, I will highlight some of the notable papers of the year. You can find the most notable papers, as selected by CSF Steering Committee Chair Professor Iain McInnes, with links to their respective detailed summaries below:
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-2020-21841220Both 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...
Efficacy and Safety of Long-Term Baricitinib With and Without Methotrexate for the Treatment of Rheumatoid Arthritis: Experience With Baricitinib Monotherapy Continuation or After Switching From Methotrexate Monotherapy or Baricitinib Plus Methotrexate.
Arthritis Care Res (Hoboken) 2020;72(8):1112-1121This 24-week update from the baricitinib RA-BEYOND LTE study follows patients previously treated in the pivotal study RA-BEGIN. It demonstrates the maintained safety and efficacy of baricitinib monotherapy, and the effects of concurrent MTX treatment on response rates and patient reported outcomes. Previous P3 study RA-BEGIN demonstrated the superior efficacy of 4mg baricitinib compared to MTX monotherapy up to 52 weeks, with no major safety events being identified. At the end of the trial, pati...
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;79:778-786This 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...
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-2020-001174This 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...
Highlights of 2019
Please click the links below to go to the CSF review of each paper2019 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...
