Factors influencing the use of biologic therapy and adoption of treat-to-target recommendations in current european rheumatology practice

Objective: The aim of this study was to identify factors that influence treatment adjustments and adoption of a treat-to-target (T2T) strategy in patients with rheumatoid arthritis (RA) in European practices. Methods: Cross-sectional data were drawn from the Adelphi 2014 RA Disease Specific Programme. Treatment patterns and clinical characteristics were investigated in patients treated with biologic disease-modifying antirheumatic drugs (bDMARDs) vs non-bDMARDs. For the T2T analysis, patients were subdivided into two subsets (RA diagnosis <2 or 652 years) and compared according to the approach used (no target = no T2T approach; pragmatic = target different from remission; and aspirational = target set as remission). Results: Data from 2,536 patients were analyzed (mean age: 52.76 years and mean time since RA diagnosis: 6.05 years). Of the 1,438 patients eligible to receive bDMARDs, 55% did not receive them. Initiation of bDMARDs in a bDMARD-na\uefve patient was prompted by worsening of the disease. In the RA diagnosis <2 years subset, a T2T approach was not adopted in 58% of the patients, whereas 8% and 34% adopted a pragmatic and aspirational approach, respectively. In the RA diagnosis 652 years subset, 45%, 19%, and 36% of the patients adopted a no target, pragmatic, and aspirational approach, respectively. Physician satisfaction with RA control was lower in the RA diagnosis <2 years subset than in the RA diagnosis 652 years subset (65% vs 77% satisfied, respectively; P<0.0001). Conclusion: This analysis shows that the use of bDMARDs remains suboptimal and that a T2T strategy is not universally adopted

Systematic review and network meta-analysis of combination and monotherapy treatments in disease-modifying antirheumatic drug-experienced patients with rheumatoid arthritis: analysis of American College of Rheumatology criteria scores 20, 50, and 70

The objective of this systematic review and meta-analysis was to compare the relative efficacy of EU-licensed bDMARD combination therapy or monotherapy for patients intolerant of or contraindicated to continued methotrexate.Methods: Comprehensive, structured literature searches were conducted in Medline, Embase, and the Cochrane Library, as well as hand-searching of conference proceedings and reference lists. Phase II or III randomized controlled trials reporting American College of Rheumatology (ACR) criteria scores of 20, 50, and 70 between 12 and 30 weeks' follow-up and enrolling adult patients meeting ACR classification criteria for rheumatoid arthritis previously treated with and with an inadequate response to conventional DMARDs were eligible. To estimate the relative efficacy of treatments whilst preserving the randomized comparisons within each trial, a Bayesian network meta-analysis was conducted in WinBUGS using fixed and random-effects, logit-link models fitted to the binomial ACR 20/50/70 trial data.Results: The systematic review identified 10,625 citations, and after a review of 2450 full-text papers, there were 29 and 14 eligible studies for the combination and monotherapy meta-analyses, respectively. In the combination analysis, all licensed bDMARD combinations had significantly higher odds of ACR 20/50/70 compared to DMARDs alone, except for the rituximab comparison, which did not reach significance for the ACR 70 outcome (based on the 95% credible interval). The etanercept combination was significantly better than the tumor necrosis factor-α inhibitors adalimumab and infliximab in improving ACR 20/50/70 outcomes, with no significant differences between the etanercept combination and certolizumab pegol or tocilizumab. Licensed-dose etanercept, adalimumab, and tocilizumab monotherapy were significantly better than placebo in improving ACR 20/50/70 outcomes. Sensitivity analysis indicated that including studies outside the target population could affect the results.Conclusion: Licensed bDMARDs are efficacious in patients with an inadequate response to conventional therapy, but tumor necrosis factor-α inhibitor combination therapies are not equally effective.Keywords: bDMARD, rheumatoid arthritis, etanercept, systematic review, network meta-analysis, comparative effectivenes
