Tofacitinib or adalimumab versus placebo: patient-reported outcomes from a phase 3 study of active rheumatoid arthritis

Strand et al. Rheumatology (Oxford). 2016 Feb 29. doi:pii: kev442. [Epub ahead of print]

RA not only affects the physical aspects of a patient’s health but also has an impact on the psychological well-being causing a significant disease burden. This paper reports on the patient-reported outcomes (PROs) from the ORAL Standard study. This study investigated tofacitinib 5mg BID, 10mg BID, adalimumab vs. placebo over 12 months with a primary endpoint at month 3. All treatment groups showed significant improvements over placebo in HAQ-DI, PtGA and Pain with LSM changes in baseline sustai...

Clinical Relevance of VPAC1 Receptor Expression in Early Arthritis: Association with IL-6 and Disease Activity

 PLoS ONE 11(2): e0149141. doi:10.1371/journal. pone.0149141

VPAC1 and VPAC2 both mediate anti-inflammatory and immunoregulatory responses in RA. Both these are receptors of vasoactive intestinal peptide (VIP), a broadly distributed peptide found in neural, endocrine and immune cells, which triggers biological response when interacting with the aforementioned receptors. It has recently been described in Martinez et al. that those patients with low levels of VIP have worse disease outcome.1This study analyzed 250 blood samples from the Princesa early Arthr...

Comparative effects of biologics on cardiovascular risk among older patients with rheumatoid arthritis

Ann Rheum Dis 2016;0:1–6 doi:10.1136/ annrheumdis-2015-207870 [Epub ahead of print]

Since RA patients are at an increased risk of a CV event, there have been several studies to determine if RA treatments alter this risk. In a retrospective study, Zhang and colleagues assess the risk of CV events in patients initiating bDMARDs.Using Medicare medical and pharmacy claims data, the incidence rate (IR) of acute myocardial infarction (AMI) and of a composite CHD* was calculated across RA patients initiating 8 different biologics: ABA, ADA, CER, ETA, GOL, INF, RIT, and TOC. There were...

Pregnancy outcome after tocilizumab therapy in early pregnancy – a case series from the German Embryotox Pharmacovigilance Center

Reproductive Toxicology doi:10.1016/j.reprotox.2016.01.002

MTX users have an increased incidence of spontaneous abortions (SABs) compared to baseline risk (42.5%1 vs. 13-17%2). Tocilizumab (TCZ) has been shown to have similar efficacy with or without MTX. There is currently limited data on the effect of TCZ on pregnancy, but with more safety data, TCZ could be an alternative for RA patients of reproductive age. The patients were enrolled at Embryotox Berlin, a pharmacovigilance center providing risk assessment during pregnancy, between 2011 and 2014 dur...

Comparison of adding tocilizumab to methotrexate with switching to tocilizumab in patients with rheumatoid arthritis with inadequate response to methotrexate: 52-week results from a prospective, randomised, controlled study (SURPRISE study)

Ann Rheum Dis 2016 Jan 5 DOI: 10.1136/annrheumdis-2015-208426 [Epub ahead of print

MTX is the primary drug in RA management because of its long-term effectiveness and safety profile; however, in patients who have insufficient response (IR) to MTX, treatment adjustments are needed – either to combine a bDMARD with MTX or to switch to a bDMARD from MTX. In the SURPRISE study, the efficacy and safety of adding TCZ to MTX (ADD-ON) or switching MTX to TCZ (SWITCH) was evaluated in 233 patients with moderate to highly active RA who were randomised 1:1. Both treatment groups were adm...

Impact of obesity on the clinical outcome of rheumatologic patients in biotherapy

Autoimmunity Reviews Doi: 10.1016/j.autrev.2016.01.010

Obesity is increasingly becoming a public health concern as its prevalence continues to grow in the United States and Western nations. Obesity has been shown to be an inflammatory condition that impacts multiple tissues and systems, including the immune system possibly linking to rheumatic diseases. In this review, Iannone et al overview the epidemiology and clinical outcomes of PsA and/or RA patients with comorbid obesity.Large cohort and prospective studies in Italy, the US, and the UK have s...

Systematic review and meta-analysis of serious infections with tofacitinib and biologic disease-modifying antirheumatic drug treatment in rheumatoid arthritis clinical trials

Arthritis Res Ther. 2015 Dec 15;17(1):362

Tofacitinib is an oral Janus kinase inhibitor for the treatment of RA. By modulating the signalling of cytokines that are integral to lymphocyte activation, proliferation, and function, tofacitinib may suppress multiple elements of immune response. A systematic literature search including all biologics and tofacitinib procured 66 RCTs and 22 LTEs that were included in a meta-analysis to provide estimated incidence rates, risk ratios, and risk differences of serious infection for each therapy. Es...

Cytokines in rheumatoid arthritis – shaping the immunological landscape

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

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...

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

Arthritis Research & Therapy (2015) 17:319 DOI: 10.1186/s13075-015-0835-7

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...

Effectiveness of tocilizumab with and without synthetic disease-modifying antirheumatic drugs in rheumatoid arthritis: results from a European collaborative study

Ann Rheum Dis. 2015 Sep 15. doi:10.1136/ annrheumdis-2015-207760

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, ...
