Pathogenetic Insights from the Treatment of Rheumatoid Arthritis

Lancet 2017;389:2328–37 DOI 10.1016/S0140-6736(17)31472-1

This review paper examines the understanding gained from looking at the effects of specific immune interventions in the treatment of RA.The introduction of novel IL-6 agents has provided the ideal opportunity to explore the distinct effect of cytokine inhibition, as opposed to receptor inhibition, at the molecular level. Mechanistic insights into TNF could also be obtained in the future with advanced molecular and informatics approaches, and future biopsy studies will be important to explore the...

Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of Filgotinib, a Selective Janus kinase 1 Inhibitor, after Short-term Treatment of Rheumatoid Arthritis: Results of Two randomized Phase IIA Trials

Arthritis Rheumatol. 2017 Oct;69(10):1949-1959. doi: 10.1002/art.40186

In two 4-week exploratory Phase 2a trials in MTX-inadequate responder (IR) patients with RA, the highly selective JAK1 inhibitor filgotinib met the primary endpoint of ACR20 at Week 4, showing greater response than placebo.Study 1, a proof-of-concept study, included 127 patients randomised to placebo, filgotinib 100 mg BID or filgotinib 200 mg QD. Study 2, was a dose-ranging study and included 91 patients randomised to placebo, filgotinib 30 mg QD, filgotinib 75 mg QD, filgotinib 150 mg QD or fi...

Biologics or Tofacitinib for People with Rheumatoid Arthritis Naïve to Methotrexate: a Systematic Review and Network Meta-analysis

Cochrane Database Syst Rev. 2017 May 8;5:CD012657. doi: 10.1002/14651858.CD012657

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...

Estimated Medical Expenditure and Risk of Job Loss among Rheumatoid Arthritis Patients undergoing Tofacitinib Treatment: Post Hoc Analyses of Two Randomized Clinical Trials

Rheumatology doi: 10.1093/rheumatology/kex087

The results of this post hoc analysis of two Phase 3 studies of tofacitinib (TOF) show that improvements in health-related quality of life related to TOF treatment are likely to translate into significant reductions in estimated medical expenditure and likelihood of current and future job loss. Data from 399 MTX inadequate responder (IR) patients from ORAL Step, and 716 TNF inhibitor (TNFi)-IR patients from ORAL Standard were included in this analysis. Patients were receiving 5 mg or 10 mg TOF B...

Tofacitinib as induction and maintenance therapy for ulcerative colitis

N Engl J Med. 2017 May 4;376(18):1723-1736. DOI 10.1056/NEJMoa1606910

Tofacitinib, at a dose of 10 mg twice daily, was more effective than placebo for induction of remission and mucosal healing in patients with moderately to severely active ulcerative colitis. Furthermore, maintenance therapy with tofacitinib, at a dose of either 5 mg or 10 mg twice daily, was more effective than placebo in sustaining remission and mucosal healing.

EULAR Recommendations for the Management of Rheumatoid Arthritis with Synthetic and Biological Disease-modifying Antirheumatic Drugs: 2016 Update

Ann Rheum Dis Published Online First: 06March2017. doi:10.1136/annrheumdis-2016-210715

The EULAR 2016 recommendations update, based on three systematic literature reviews (SLRs) and expert opinion, comprises four overarching principles and 12 recommendations compared with 14, respectively, in 2013. These recommendations intend to inform regarding EULAR’s most recent consensus on the management of RA, with the aim of attaining the best outcomes with current therapies.All DMARD types: csDMARDs, bDMARDs, tsDMARD and bsDMARD are addressed, and cost aspects are taken into consideration...

Sarilumab improves Patient-reported Outcomes in Rheumatoid Arthritis Patients with Inadequate Response/Intolerance to Tumour Necrosis Factor Inhibitors

RMD Open 2017;3:e000416. DOI:10.1136/rmdopen-2016-000416

Evidence is presented that treatment with sarilumab demonstrates patient-reported benefits in TNF-IR patients with moderate to severe RA. These improvements complement the clinical efficacy previously reported for sarilumab, and are consistent with those seen in the MOBILITY trial (MTX-IR patients)1, yet in a more difficult-to-treat population.Data were analysed from the 24-week Phase 3 TARGET randomised controlled trial in adult patients with active RA and previous inadequate response or intole...

Analysis of Haematological Changes in Tofacitinib-treated Patients with Rheumatoid Arthritis across Phase 3 and Long-term Extension Studies

Rheumatology 2017;56:46–57.

In this analysis examining haematological changes after tofacitinib (TOF) treatment in patients with RA from pooled Phase 3 and LTE studies, TOF decreased mean lymphocyte counts and slightly increased mean haemoglobin (Hb) levels. The Phase 3 population included patients from six trials (n=4271) of TOF 5- or 10 mg BID, placebo or active comparator up to 24 months. The LTE population (n=4858) included patients from two studies (of up to 84 months), who had participated in Phase 1, 2 or 3 TOF stud...

Peficitinib, a JAK Inhibitor, in Combination with Limited Conventional Synthetic DMARDs in the Treatment of Moderate-to-severe Rheumatoid Arthritis

Arthritis Rheumatol DOI 10.1002/art.40054. Accepted article.

In this Phase 2b study in patients with moderate to severe RA, once-daily peficitinib in combination with limited csDMARDs reduced the symptoms of RA, demonstrated adose-dependent ACR20 response rate over 12 weeks, and showed acceptable tolerability. This 12-week study included patients who had an inadequate response or intolerance to csDMARDs (N=289). Patients were randomised 1:1:1:1:1 to peficitinib 25-, 50-, 100, 150 mg or matching placebo. Statistically significant differences in the ACR20 r...

Baricitinib in Patients with Inadequate Response or Intolerance to Conventional Synthetic DMARDs: Results from the RA-BUILD Study

Ann Rheum Dis 2017;76:88–95.

Baricitinib improved symptoms of RA in the RA-BUILD trial, a Phase 3 study of baricitinib in patients with moderately to severely active RA, refractory to or intolerant to csDMARDs. As well as providing a short-term (24 weeks) benefit, there appeared to be joint damage benefit, considered a marker of long-term disability.RA-BUILD was a 24-week randomised, double-blind, placebo-controlled parallel-group study. Patients were randomised 1:1:1 to receive once-daily doses of placebo (n=228) or barici...
