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...

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, ...

Filgotinib, a JAK1 Inhibitor, Modulates Disease Related Biomarkers in Rheumatoid Arthritis: Results from Two Randomized, Controlled Phase 2b Trials

Rheumatol Ther. 2020 DOI: 10.1007/s40744-019-00192-5

In this study examining the effect of FIL on a panel of biomarkers, FIL down-modulated several key inflammatory mediators of signalling pathways in RA - independent of MTX background therapy. This confirmed the strong network effects of the JAK1 node in autoimmunity, matrix and cartilage degradation, angiogenesis, and leukocyte adhesion and recruitment. Biomarkers key to RA pathophysiology were measured at baseline, Wk4 and Wk12 in FIL 100 mg, FIL 200 mg or PBO treatment groups from two phase 2b...

Preferential Inhibition of JAK1 Relative to JAK3 by Upadacitinib: Exposure-Response Analyses of Ex Vivo Data From 2 Phase 1 Clinical Trials and Comparison to Tofacitinib

Pharmacodynamics. 2020

Ex vivo pharmacodynamic assay results demonstrated a greater selectivity of UPA on JAK1 versus JAK3 compared to TOF. This analysis conducted ex vivo stimulation of STAT3 phosphorylation by IL-6 as a measure of JAK1 activity and STAT5 phosphorylation by IL-7 as a measure of JAK1/JAK3 activity. Change in pSTAT3 and pSTAT5 were calculated at 1, 6 and 12 hours following drug administration using samples collected from healthy subjects and subjects with RA, from 2 phase 1 studies. Exposure-response m...

2018 brought a wealth of new data in cytokine signalling and IL-6 that helps inform current clinical practice and brings the promise of new options in the future. There was good data on the use of sub cutaneous tocilizumab as well as strategies in early RA and for methotrexate tapering. For the currently marketed JAK inhibitors, tofacitinib and baricitinib, continuous long-term efficacy and safety data further support its current use and applications. On the development side, the outcomes of the...

Two Years of Sarilumab in Patients with Rheumatoid Arthritis and an Inadequate Response to MTX: Safety, Efficacy and Radiographic Outcomes

Rheumatology 2018;57:1423–1431 DOI: 10.1093/rheumatology/key121

Two-year treatment of active, moderate-to-severe RA with sarilumab, along with dose reduction in the event of laboratory abnormalities, resulted in durable efficacy outcomes and a safety profile consistent with previous reports involving IL-6R inhibition. Durable long-term safety and efficacy, reduced joint damage progression, and conserving health-related quality of life and work productivity are important goals of therapy in RA.1 Sarilumab significantly reduced disease activity, improved physi...

Radiographic Joint Damage in Early Rheumatoid Arthritis Patients: Comparing Tocilizumab- and Methotrexate-based Treat-to-target Strategies

Rheumatology (Oxford) 2018; 57(2):309–17

Tocilizumab (TCZ) therapy in DMARD-naïve patients with RA, is more effective at reducing erosion progression, particularly in the feet, compared with treat-to-target methotrexate (MTX) therapy. This analysis looked at radiographic joint damage, including separate examination of erosion progression and joint space narrowing (JSN) in the hands and feet of patients enrolled in the U-Act-Early trial. Radiographic damage is a common symptom of RA, with treat-to-target strategies aimed at preventing ...

Impact of Tocilizumab Monotherapy On Patient-Reported Outcomes in Patients With Rheumatoid Arthritis from Two Randomised Controlled Trials

RMD Open;3:e000496. doi: 10.1136/rmdopen-2017-000496

This post hoc analysis of 2 randomised controlled trials (RCTs) AMBITION and ADACTA found that tocilizumab monotherapy results in substantial and clinically meaningful improvements in patient-reported outcomes (PROs) over 24 weeks.PROs assessed included patient global assessment (PtGA), pain, HAQ-DI, Functional Assessment of Chronic Illness Therapy (FACIT-F) and Short-Form-36 (SF-36) physical component summary (PCS) and mental component summary (MCS) and eight domain scores.Tocilizumab (TCZ) mon...

Transaminase Levels and Hepatic Events During Tocilizumab Treatment: Pooled Analysis of Long-Term Clinical Trial Safety Data in Rheumatoid Arthritis

Arthritis Rheumatol. 2017 Sep;69(9):1751-1761. doi: 10.1002/art.40176

In this pooled analysis investigating liver enzyme abnormalities and hepatic adverse events (AEs) during long-term tocilizumab (TCZ) treatment for RA in clinical trials, although transaminase elevations were frequent, rates of hepatic serious AEs remained low. Data were pooled from patients who received ≥1 dose of IV TCZ with or without DMARDs in Phase 3 or 4 clinical trials, long-term extensions, and a pharmacology study.A total of 4171 patients were included in the all-exposure population with...
