Cytokines in rheumatoid arthritis – shaping the immunological landscape

Nat Rev Rheumatol. 2016 Jan;12(1):63-8

McInnes I,

Buckley C,

Isaacs J

Cytokine-mediated pathways are central to the pathogenesis of rheumatoid arthritis and there has been great advances in understanding and clinical application in the last 20 years. McInnes and colleagues provide a timely and succinct overview the roles of cytokine families in the various phases and tissue compartments of this disease. They particularly review the combinatorial role played by cytokines in mediating the overlapping innate and adaptive immune responses associated with disease onset...

VX-509 (decernotinib) is a novel oral, selective inhibitor of JAK-3. JAK-3 is a member of the JAK signalling family that is primarily expressed in hematopoietic cells and associates with only the common γ-chain making it a promising therapeutic drug target. A phase IIb 24-week study of VX-509 in 358 patients with RA, who had prior inadequate response to MTX, uses ACR20 response rate and DAS28-CRP change at Week 12 to assess the efficacy of VX-509. Patients were administered either placebo+MTX or...

RA patients have increased risk of CVD compared with the general population that is not fully explained by traditional risk factors. This is a post-hoc analysis of data from a clinical trial that compared IL-6 and TNF-α signaling inhibition to compare changes in lipids and lipid-associated CV risk markers in 324 patients treated with TCZ IV q4w or ADA SC q2w for 24 weeks. HDL-SAA and sPLA2 IIA is also measured in an additional subpopulation of 87 and 97 TCZ and ADA patients, respectively.Greater...

Incidence and complications of interstitial lung disease in users of tocilizumab, rituximab, abatacept and anti-tumor necrosis factor α agents, a retrospective cohort study

Interstitial lung disease (ILD) is a common extra-articular condition for RA patients. This retrospective cohort study of health insurance databases investigates the ILD incidence and exacerbation between ABA, TCZ, RTX, and anti-TNFα agents in adult RA patients with prior biologic therapy. Two definitions of ILD were used: one specific, one sensitive; descriptive results were produced for both. In patients with no history of ILD, the overall incidence rate of ILD ranged from 1.8% to 6.4% (depend...

RA presents a significant health and socioeconomic burden particularly in physical functioning, fatigue, and emotional roles. A phase III 6-month study of tofacitinib in patients with active RA, who had prior inadequate responses to cDMARDs or bDMARDs, uses patient-reported outcomes (PROs) to assess the impact on quality of life. Patients were randomized 4:4:1:1 to receive tofacitinib 5 or 10 mg BID, or placebo for 3 months followed by tofacitinib 5 or 10 mg BID. At month 3, tofacitinib 5 and 10...

Tofacitinib regulates synovial inflammation in psoriatic arthritis, inhibiting STAT activation and induction of negative feedback inhibition

Psoriatic arthritis (PsA) is a chronic inflammatory arthritis associated with psoriasis (Ps) and characterised by synovitis and progressive destruction of articular cartilage and bone. Recently developed agents for PsA target IL12p40, IL-6 and IL-17, several of which signal through the JAK family of receptor-associated tyrosine kinases. Tofacitinib is a drug of the JAK inhibitor class and is currently approved for the treatment of RA in 27 countries. This study evaluated the effect of tofacitini...

Biological DMARDs have markedly changed the management and outcome of rheumatoid arthritis. Most international guidelines recommend the use of biological DMARDs in combination with MTX or other synthetic DMARDs (sDMARDs) (where MTX is not tolerated or contraindicated), based primarily on the observation that MTX enhances the efficacy of TNF antagonists in both clinical trials and observational studies.This study examined the effectiveness of tocilizumab (TCZ), an anti-IL-6 monoclonal antibody, ...

This Phase II study assessed the safety and efficacy of olokizumab in Asian patients with moderate-to-severe rheumatoid arthritis, previously exposed to anti-TNF therapy. After 12 weeks of treatment, olokizumab was found to rapidly improve disease activity in patients who had previously failed anti-TNF therapy. There was also a significant decrease in ACR20 and ACR50 responder rates at week 12. The safety findings were consistent with the safety profile expected for this drug class. These findin...

Cost-effectiveness of Tofacitinib in the Treatment of Moderate to Severe Rheumatoid Arthritis in South Korea

This study evaluated the cost-effectiveness of introducing tofacitinib, an oral Janus kinase inhibitor, to the treatment of Korean patients with RA and an inadequate response to conventional DMARDs. The model showed that the inclusion of tofacitinib as a treatment strategy for moderate to severe RA is cost-effective; this conclusion was considered robust based on multiple sensitivity analyses.First-line tofacitinib used before the standard of care (base-case analysis) increased both treatment c...

This study compared the clinical outcomes at one year after the treatment either abatacept or tocilizumab in routine clinical practice. This study employed propensity score matching and demonstrated that abatacept and tocilizumab had comparable continuing efficacies, and that treatment with the drugs resulted in comparable clinical and functional remission rates. Additionally, abatacept and tocilizumab showed similar effectiveness with or without MTX.While clinical efficacies, including SDAI, w...
