Tocilizumab (TCZ), abatacept (ABA) and tofacitinib (TOF) appear to have no major safety concerns for treatment of RA patients with hepatitis C virus (HCV) infections.HCV is an infectious disease which continues to present a major therapeutic challenge for clinicians in treating patients with RA. Previous reports demonstrate that the use of TNF targeted therapies in RA patients with HCV infections appear to have no major safety concerns. During short-term therapy with TCZ and ABA, data has shown ...

Two-year treatment of active, moderate-to-severe RA with sarilumab, along with dose reduction in the event of laboratory abnormalities, resulted in durable efficacy outcomes and a safety profile consistent with previous reports involving IL-6R inhibition. Durable long-term safety and efficacy, reduced joint damage progression, and conserving health-related quality of life and work productivity are important goals of therapy in RA.1 Sarilumab significantly reduced disease activity, improved physi...

Pharmacokinetics of Upadacitinib with Clinical Regimens of the Extended-Release Formulation Utilized in Rheumatoid Arthritis Phase 3 Trials

Upadacitinib (UPA) extended release (ER) formulation dosing achieved the target profile that enables single dosing in patients with RA. In early clinical studies, UPA was given as an immediate release (IR) formulation, however patients were noted to experience fluctuations in blood plasma concentrations. To enhance patient compliance in UPA Phase 3 trials, ER tablets have been developed. Here, authors aimed at characterising the pharmacokinetics of UPA single and multiple doses of ER compared wi...

Tapering versus Steady-state Methotrexate in Combination with Tocilizumab for Rheumatoid Arthritis: a Randomised, Double-blind Trial

Methotrexate (MTX) tapering in patients with active, severe RA receiving intravenous tocilizumab (TCZ) was non-inferior to continuing stable MTX doses in maintaining a good/moderate EULAR response. Although MTX and bDMARD combination therapy may produce better response rates than bDMARD monotherapy, one third of patients discontinue or are non-compliant with MTX due to preference or toxicity. This randomised, non-inferiority study investigated the efficacy and tolerability of MTX tapering and ma...

Patient-reported outcomes (PROs) vastly improved in the first 24 weeks post-initiation of tocilizumab (TCZ) therapies compared to methotrexate (MTX) monotherapy in the U-Act-Early trial.U-Act-Early was a two-year, treat-to-target study that compared the safety and efficacy of TCZ and MTX treatment strategies in DMARD-naïve patients with early RA. Sustained remission was classed as more effective in patients given TCZ monotherapy or combination therapy with MTX compared to MTX alone. TCZ therapie...

This study showed that in patients who achieved low disease activity (LDA), it is possible to discontinue tofacitinib without flare in approximately one-third of patients. Patients from the tofacitinib Phase 3 programme and long-term extension study were enroled. Discontinuation was based on physician-patient decision making with informed consent. The primary endpoint was the proportion of patients who remained tofacitinib free at post-treatment Week 52. Of 64 patients treated with tofacitinib w...

In this analysis of the effect of baricitinib on changes in lipid profile, lipoprotein particle size and apolipoprotein content, increases in serum lipids were observed with HDL-C increases correlating with improved clinical outcomes.Eligible patients (N=301) met the inclusion criteria for the Phase 2b randomised, double-blind, placebo-controlled study.1 Patients were assigned in a 2:1:1:1:1 ratio to once-daily doses of placebo or baricitinib 1, 2, 4, or 8 mg, respectively. Those receiving 2 mg,...

Baricitinib in Patients with Refractory Rheumatoid Arthritis

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

Genovese et al.

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...

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

Seoane I,

Ortiz A,

Piris L et al

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...

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

Autoimmunity Reviews Doi: 10.1016/j.autrev.2016.01.010

Iannone et al

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...
