McInnes. I

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...

The rate of Herpes Zoster (HZ) in tofacitinib (TOF) users with concomitant glucocorticoids (GC) was approximately double that of other TOF combination therapies.TOF is an effective treatment for RA. Increased HZ risk has been observed with the use of JAK inhibitors, whereas the HZ risk with biologics and targeted RA therapies are comparable. This study evaluated the HZ risk in TOF users according to concomitant GC, MTX, both, or neither. MarketScan and Medicare data were used to identify 8030 rh...

A Network Meta-Analysis Comparing Efficacy and Safety of Tofacitinib and Baricitinib

Z Rheumatol. 2018 Sep 6. DOI 10.1007/s00393-018-0531-5

Bae SC and Lee YH

Tofacitinib (TOF) 10mg and baricitinib (BARI) 4mg, in combination with methotrexate (MTX), were the most efficacious treatments in RA patients with an inadequate response to DMARDs or biologics. Both combination treatments presented acceptable safety profiles and were not associated with a significant risk of serious adverse events.This study employed a Bayesian approach to Meta-Analysis; combining the available evidence across a network of Randomised Controlled trials (RCTs).Twelve RCTs contai...

The b/tsDMARDs evaluated in this systematic literature review (SLR) were shown to be efficacious as monotherapies, although combination therapies usually achieved better treatment outcomes.Current treatment guidelines recommend combining b/tsDMARDs with MTX in the treatment of RA; however, up to a third of patients are treated with monotherapy. While previous SLRs1–3 have compared the efficacy of b/tsDMARD mono- versus MTX combination therapy they covered a limited number of randomised controlle...

Patient Characteristics Influence the Choice of Biological Drug in RA, and will make non-TNFi Biologics appear more Harmful than TNFi Biologics

Analysis of patient characteristics revealed that older and less healthy patients with RA were more likely to receive non-TNFi bDMARDs as a first bDMARD compared to other treatments.This study aimed to describe patient characteristics at initiation of bDMARD treatment at two-time points: first bDMARD initiation and switch to second bDMARD after TNFi treatment. The second aim of the study was to estimate the potential of treatment channelling to confound results in comparative treatment studies i...

Effectiveness and Safety of Tofacitinib in Rheumatoid Arthritis: a Cohort Study

A retrospective cohort study of tofacitinib (TOF) revealed that patients previously treated with methotrexate who initiated TOF, presented no differences in hospitalised infections or effectiveness, compared with non-TNF biologics. Currently, TOF is recommended in ACR and EULAR guidelines as an alternative to biologics after first-line cDMARD therapy. Previous indirect comparisons have shown that patients with RA who experience cDMARD failure show similar efficacy when given TNFis, abatacept, to...

Treatment Persistence and Healthcare Costs Among Patients with Rheumatoid Arthritis Changing Biologics in the USA

Updated treatment guidelines recommend the use of different mechanism of action (MOA) therapies earlier in the treatment course. Clinical studies have revealed that this approach may be better than TNFi cycling, and may be more cost effective.This study of Commercial and Medicare Advantage claims data showed that patients who switched MOA had higher treatment persistence and lower healthcare costs than TNFi cyclers.After the first TNFi claim, patients either cycled to another TNFi (n=935) or swi...

A Comparison of Discontinuation Rates of Tofacitinib and Biologic Disease-modifying Anti-rheumatic Drugs in Rheumatoid Arthritis: a Systematic Review and Bayseian Network Meta-analysis Regression

Based on a Bayesian network meta-analysis (NMA) in patients with RA who previously showed failure with csDMARDs or biologics, discontinuation rates between tofacitinib (TOF) and biologics (TNFis, abatacept [ABT], rituximab [RTX] and tocilizumab [TCZ]) differed based on previous treatments and reasons for discontinuation.Data were collected from randomised controlled trials (RCT) found from literature searches from the Cochrane Central Register of Controlled Trials (CENTRAL) and MEDLINE. Disconti...

This Cochrane systemic review and network meta-analysis looked at the benefits and harms of biologics or tofacitinib in patients with RA not previously treated with MTX.Using data from 19 RCTs including 6,485 participants, the review found that biologics (abatacept, adalimumab, etanercept, golimumab, infliximab, rituximab) in combination with MTX improved signs and symptoms of RA (ACR50) and increased the chances of remission (DAS <1.6 or DAS28 <2.6). There was also some evidence of an improveme...

The Emerging Safety Profile of JAK Inhibitors in Rheumatic Disease

Nature Reviews Rheumatology 2017;13:234–43

Kevin L. Winthrop

This review discusses the current understanding of the safety of JAK inhibitors, including providing an overview of the changes in laboratory parameters, infection and malignancy risks associated with each JAK inhibitor compound.The review discusses the adverse event profiles and cellular changes characteristically seen with each JAK inhibitor, as well as the overlap or differences between the various compounds. The relative specificities for different JAKs between each compound do not always p...
