Baricitinib in Patients with Refractory Rheumatoid Arthritis

N Engl J Med. 2016 Mar 31;374(13):1243-52. doi: 10.1056/NEJMoa1507247

For patients who have an inadequate response or unacceptable side effects associated with biologic DMARDs, the options for treatment beyond conventional DMARDs are limited. This phase 3 trial of the JAK 1/2 inhibitor, baricitinib, studied its efficacy in bDMARD-IR patients. 527 patients were randomized to either baricitinib 2mg, 4mg or placebo for up to 24 weeks. At week 12 the primary endpoints were tested hierarchically to control type 1 error; these endpoints were ACR20, HAQ-DI score, DAS28-C...
Increased inflammation and CV disease have been associated with lower total cholesterol (TC) and low density lipoprotein (LDL-C) levels in RA patients – an apparent paradox to what is observed in the general population. Previously, reduced high-density lipoprotein (HDL-C) levels have been associated with increased risk of CV, and an inverse relationship observed with levels of HDL-C level and C-reactive protein (CRP).This analysis of the literature with regard to studies using DMARDs in RA patie...
Biologics are used to treat several inflammatory diseases, including RA, PsO, PsA, and AS; however, the cost of biologic therapies is high compared to non-biologic DMARDs. By using evidence-based assessment of comparative costs between biologics, healthcare resources can be properly allocated. This study used medical and pharmacy claims data to assess the utilitisation and cost of biologic treatment for RA, PsO, PsA, and AS. ETN (45%), ADA (32%), and INF (9%) were the most common medications and...

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...
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...
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...
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...
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...

One of the major challenges of RA treatment is choosing the correct treatment and dose for the individual patient, as treatment response can be heterogeneous. To help select the appropriate treatment, there is a need for effective and non-invasive ways to monitor disease activity and progression. In the LITHE study, Bay-Jensen et al. investigate whether early biomarker measurements could predict early joint protection response to TCZ. The biomarkers (CRPM, VICM, C1M, C2M, C3M, and CTX-I/OC [bone...
