Long-Term Effectiveness of Adalimumab in Patients with Rheumatoid Arthritis: An Observational Analysis from the Corrona Rheumatoid Arthritis Registry.

Introduction: Current recommendations for the management of rheumatoid arthritis (RA) focus on a treat-to-target approach with the objective of maximizing long-term health-related quality-of-life in patients with RA. Published studies from randomized clinical trials have reported limited data regarding the long-term efficacy and safety of adalimumab in patients with RA. This study aims to evaluate the long-term (10+ years) persistency and effectiveness of adalimumab in patients with RA in a real-world setting.

Discontinuation of Biologic Therapy in Rheumatoid Arthritis: Analysis from the Corrona RA Registry.

Introduction: Despite the availability of multiple effective therapies, discontinuation/switching of treatment is common for many patients with rheumatoid arthritis (RA). This study was designed to examine initiation of biologic disease-modifying anti-rheumatic drugs (bDMARDs) within the Consortium of Rheumatology Researchers of North America (Corrona) RA Registry, and characterize reasons for discontinuation.

Methods: Inclusion criteria were: Corrona-registered adults (≥18 years) with RA (2002-2011); age of RA onset: ≥16 years; ≥6 months' follow-up after initiation of first/subsequent bDMARD.

Impact of rituximab on patient-reported outcomes in patients with rheumatoid arthritis from the US Corrona Registry.

To evaluate the impact of rituximab on patient-reported outcomes (PROs) in a US-based observational cohort of patients with rheumatoid arthritis (RA). Patients with active RA, prior exposure to ≥1 tumor necrosis factor inhibitor (TNFi) and who newly initiated rituximab were identified. Changes in PROs were assessed 1 year after rituximab initiation.

Clinical and demographic factors associated with change and maintenance of disease severity in a large registry of patients with rheumatoid arthritis.

Background: We examined models to predict disease activity transitions from moderate to low or severe and associated factors in patients with rheumatoid arthritis (RA).

Methods: Data from RA patients enrolled in the Corrona registry (October 2001 to August 2014) were analyzed. Clinical Disease Activity Index (CDAI) definitions were used for low (≤10), moderate (>10 and ≤22), and severe (>22) disease activity states.

Sex differences in gout characteristics: tailoring care for women and men.

Background: To characterize the differences between women and men with gout.

Methods: We analyzed a US national cohort of gout patients cared for by rheumatologists.

Results: Compared with the 1012 men with gout, women with gout (n = 262) were older (71 vs.

A window of opportunity for abatacept in RA: is disease duration an independent predictor of low disease activity/remission in clinical practice?

The objective of the study was to examine whether disease duration independently predicts treatment response among biologic-naïve patients with rheumatoid arthritis (RA) initiating abatacept in clinical practice. Using the Corrona RA registry (February 2006-January 2015), biologic-naïve patients with RA initiating abatacept with 12-month (±3 months) follow-up and assessment of disease activity (Clinical Disease Activity Index [CDAI]) at initiation and at 12 months were identified. The primary outcome was mean change in CDAI (ΔCDAI) from baseline to 12 months.

Brief Report: The Role of Rare Protein-Coding Variants in Anti-Tumor Necrosis Factor Treatment Response in Rheumatoid Arthritis.

Objective: In many rheumatoid arthritis (RA) patients, disease is controlled with anti-tumor necrosis factor (anti-TNF) biologic therapies. However, in a significant number of patients, the disease fails to respond to anti-TNF therapy. We undertook the present study to examine the hypothesis that rare and low-frequency genetic variants might influence response to anti-TNF treatment.

Delays in Initiation of Disease-Modifying Therapy in Rheumatoid Arthritis Patients: Data from a US-Based Registry.

Introduction: The goal of this study was to evaluate how frequently rheumatoid arthritis (RA) therapy is instituted promptly and to describe the characteristics of patients who are not treated early upon diagnosis.

Methods: The percentage of patients who at the time of enrollment in the Corrona registry were not receiving any RA-directed therapy was evaluated and their characteristics were summarized. The time to subsequent initiation of any RA-directed therapy was also estimated.

Dosing of Intravenous Tocilizumab in a Real-World Setting of Rheumatoid Arthritis: Analyses from the Corrona Registry.

Introduction: In the United States, the recommended starting dose of intravenous tocilizumab (TCZ) is 4 mg/kg every 4 weeks, with an increase to 8 mg/kg based on clinical response for patients with moderate to severe rheumatoid arthritis; however, data on how TCZ dose is escalated in real life are missing. The objective of this analysis was to describe patterns of early intravenous TCZ dose escalation in a real-world setting using data from the Corrona registry.

Methods: All patients enrolled in the comparative effectiveness substudy (CERTAIN) nested within Corrona who initiated TCZ and completed 3- and 6-month study visits were eligible for inclusion.

Risk of Infection Associated With Subsequent Biologic Agent Use After Rituximab: Results From a National Rheumatoid Arthritis Patient Registry.

Objective: To assess whether the time between the last rituximab infusion and initiation of a different biologic agent influenced infection risk in patients with rheumatoid arthritis (RA).

Methods: Patients with RA who newly initiated rituximab within the Consortium of Rheumatology Researchers of North America registry were included if they switched to a nonrituximab biologic agent and had ≥1 followup visit within 12 months of switching. Patients were categorized by duration of time between their last rituximab infusion and initiation of a subsequent biologic agent (≤5 months, 6-11 months, and ≥12 months).

Points to consider for reporting, screening for and preventing selected comorbidities in chronic inflammatory rheumatic diseases in daily practice: a EULAR initiative.

In chronic inflammatory rheumatic diseases, comorbidities such as cardiovascular diseases and infections are suboptimally prevented, screened for and managed. The objective of this European League Against Rheumatism (EULAR) initiative was to propose points to consider to collect comorbidities in patients with chronic inflammatory rheumatic diseases. We also aimed to develop a pragmatic reporting form to foster the implementation of the points to consider.

Comparative effectiveness of biologic monotherapy versus combination therapy for patients with psoriatic arthritis: results from the Corrona registry.

Objectives: To characterise the comparative effectiveness of combination therapy (a tumour necrosis factor inhibitor (TNFi) and a conventional synthetic disease-modifying antirheumatic drug (csDMARD) such as methotrexate) and monotherapy (TNFi only) for psoriatic arthritis (PsA) from a large US registry.

Methods: The analysis included adult patients with PsA who were enrolled in the Corrona database (ClinicalTrials.gov, NCT01402661), had initiated a TNFi, were biologic naïve, and had a follow-up visit ≥90 days after drug initiation.

Characteristics Associated with Biologic Monotherapy Use in Biologic-Naive Patients with Rheumatoid Arthritis in a US Registry Population.

Introduction: The aim of this study was to describe factors associated with initiating a biologic as monotherapy vs in combination with a conventional disease-modifying antirheumatic drug (DMARD) in biologic-naive patients with rheumatoid arthritis (RA) enrolled in the Corrona registry.

Methods: First biologic initiations were classified as monotherapy (Bio MT) or combination therapy (Bio CMB). Baseline demographic and clinical characteristics were evaluated.

Effectiveness of Rituximab for the Treatment of Rheumatoid Arthritis in Patients with Prior Exposure to Anti-TNF: Results from the CORRONA Registry.

Objective: To characterize the real-world effectiveness of rituximab (RTX) in patients with rheumatoid arthritis.

Methods: Clinical effectiveness at 12 months was assessed in patients who were prescribed RTX based on the Clinical Disease Activity Index (CDAI). Change in CDAI was calculated (CDAI at 12 mos minus at initiation).

Evaluation of the effect of tofacitinib on measured glomerular filtration rate in patients with active rheumatoid arthritis: results from a randomised controlled trial.

Introduction: Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). During the clinical development programme, increases in mean serum creatinine (SCr) of approximately 0.07 mg/dL and 0.

TYK2 protein-coding variants protect against rheumatoid arthritis and autoimmunity, with no evidence of major pleiotropic effects on non-autoimmune complex traits.

Despite the success of genome-wide association studies (GWAS) in detecting a large number of loci for complex phenotypes such as rheumatoid arthritis (RA) susceptibility, the lack of information on the causal genes leaves important challenges to interpret GWAS results in the context of the disease biology. Here, we genetically fine-map the RA risk locus at 19p13 to define causal variants, and explore the pleiotropic effects of these same variants in other complex traits. First, we combined Immunochip dense genotyping (n = 23,092 case/control samples), Exomechip genotyping (n = 18,409 case/control samples) and targeted exon-sequencing (n = 2,236 case/controls samples) to demonstrate that three protein-coding variants in TYK2 (tyrosine kinase 2) independently protect against RA: P1104A (rs34536443, OR = 0.

Identifying factors associated with concordance with the American College of Rheumatology rheumatoid arthritis treatment recommendations.

Background: Factors associated with care concordant with the American College of Rheumatology (ACR) recommendations for the use of disease-modifying antirheumatic drugs (DMARDs) in rheumatoid arthritis (RA) are unknown.

Methods: We identified a national cohort of biologic-naive patients with RA with visits between December 2008 and February 2013. Treatment acceleration (initiation or dose escalation of biologic and nonbiologic DMARDs) in response to moderate to high disease activity (using the Clinical Disease Activity Index) was assessed.

Golimumab, a new human anti-tumor necrosis factor alpha antibody, administered intravenously in patients with active rheumatoid arthritis: Forty-eight-week efficacy and safety results of a phase III randomized, double-blind, placebo-controlled study.

Objective: To assess the efficacy and safety of intravenous administration of golimumab in patients with rheumatoid arthritis (RA).

Methods: Adult patients with RA in whom disease activity was persistent despite treatment with methotrexate (MTX) at a dosage of 15-25 mg/week for > or = 4 weeks were randomized to receive intravenous infusions of placebo plus MTX or intravenous infusions of golimumab at a dose of 2 mg/kg or 4 mg/kg, with or without MTX, every 12 weeks through week 48. Patients with <20% improvement in the swollen and tender joint counts could enter early escape and receive additional active treatment (week 16) or could have their dose regimen adjusted (week 24).
