Changes in cotherapies after initiation of disease-modifying antirheumatic drug therapy in patients with rheumatoid arthritis.

ABSTRACT: Objective. We hypothesized that initiation of a new disease-modifying antirheumatic drug (DMARD) for treatment of rheumatoid arthritis (RA) would decrease the use of corticosteroids, nonsteroidal antiinflammatory drugs (NSAIDs), and narcotics.Methods. Using administrative databases, we assembled 4 retrospective cohorts of RA patients (1998-2005) and identified 5 groups initiating DMARD regimens: methotrexate (MTX) with (new MTX) or without (first MTX) use of other nonbiologic DMARDs in the previous year; new hydroxychloroquine (HCQ) and/or sulfasalazine (SSZ; new HCQ/SSZ)and new leflunomide (new LEF), both with previous use of MTX; and new tumor necrosis factor ? (TNF?) antagonists(new anti-TNF). We compared within-person differences in any use of cotherapies (? prescription) between the 6 months before and the 6-12 months after DMARD initiation.Results. Among 32,476 DMARD initiators, the prevalence of corticosteroid, NSAID, and narcotic use increased by 15%, 5%,and 6%, respectively, in the 6 months before initiation compared to the previous 6 months, suggesting worsening of the disease. In the 6-12 months after initiation for most initiator groups, more patients stopped using corticosteroids and NSAIDs than started, with overall decreases of 8.9% (95% confidence interval [95% CI] 8.4-9.4%) for corticosteroids and 12.9% (95%CI 12.3-13.4%) for NSAIDs. The proportion of narcotic users changed little (overall decrease of 2.5%; 95% CI 1.9-3.0%).Conclusion. Use of all 3 cotherapies increased in the 6 months before initiation of new DMARD regimens for RA. Use of corticosteroids and NSAIDs decreased modestly 6-12 months after initiation, but there was only a very small decrease in narcotic use. These differential changes require further study.

Project description:IntroductionTo compare biologic disease-modifying antirheumatic drug therapy persistence between biologics among patients with rheumatoid arthritis (RA) who previously used ?1 other biologic.MethodsUsing a large United States administrative claims dataset, we identified adult patients with RA initiating abatacept, adalimumab, certolizumab, etanercept, golimumab, infliximab, or tocilizumab between January 1, 2010 and January 1, 2012 (initiation date = index). Patients were required to have used ?1 other biologic before index. Outcomes were biologic persistence, defined in two alternative ways: (1) time from initiation until switching to a different biologic (time to switch) and (2) time from initiation until switching or the first occurrence of a 90-day gap in treatment with the initiated biologic (time to switch/discontinuation). Rituximab was excluded from analyses due to retreatment based on clinical evaluation, which complicates the measurement of persistence. Multivariable survival analyses compared persistence outcomes between tocilizumab and the other biologics, adjusting for patient characteristics.ResultsThe sample comprised 9,782 biologic initiations; mean age 54 years and 82% female. Compared with tocilizumab, the hazards of switching biologic therapy were significantly higher for abatacept [hazard ratio (HR) = 1.19, P = 0.041], adalimumab (HR = 1.39, P < 0.001), certolizumab (HR = 1.39, P < 0.001), golimumab (HR = 1.20, P = 0.047), and infliximab (HR = 1.33, P < 0.001), but not significantly different for etanercept (HR = 1.19, P = 0.095); the hazards of switching/discontinuing biologic therapy were significantly higher for adalimumab (HR = 1.16, P = 0.014) and certolizumab (HR = 1.15, P < 0.012), but not significantly different for abatacept (HR = 1.08, P = 0.229), etanercept (HR = 0.97, P = 0.644), golimumab (HR = 0.99, P = 0.829), and infliximab (HR = 0.97, P = 0.721).ConclusionsThis is one of the first studies of biologic persistence to focus specifically on patients with RA who are not naïve to biologic treatment. Among patients with RA who previously used ?1 other biologic, tocilizumab-treated patients had similar or significantly better biologic persistence compared with other biologics.

Project description:IntroductionSome patients with rheumatoid arthritis (RA) using tumor necrosis factor inhibitors (TNFi) experience inefficacy or lack of tolerability and hence switch to another TNFi (cycling) or to a therapy with another mode of action (switching). This study examined patient characteristics, prescribing patterns and treatment practice for RA in the United States.MethodsData were from the Adelphi Disease Specific Programme (Q2-Q3 2016). Rheumatologists completed a survey and patient record forms for adult patients with RA who had received ≥ 1 targeted therapy. Patients were grouped by class of first-used targeted therapy, and monotherapy vs. combination therapy. TNFi patients who received ≥ 1 targeted therapy were classified as cyclers or switchers. Univariate analyses compared patient characteristics and physician factors across the analysis groups.ResultsOverall, 631 patients received ≥ 1 targeted therapy; 535 were prescribed a TNFi as first targeted therapy, 53 a nonTNFi biologic disease-modifying antirheumatic drug (bDMARD), and 43 tofacitinib. Of 577 patients with known conventional synthetic (cs) DMARD status, 18.7% were prescribed monotherapy and 81.3% combination therapy. Combination therapy patients received significantly more concomitant medications prior to initiation of first targeted therapy than monotherapy patients (P < 0.05). The top reason for physicians to prescribe first use targeted therapy was strong overall efficacy (79.9%). Of 163 patients who progressed to second targeted therapy, 60.7% were cyclers. A lower proportion of cyclers persisted on their first use targeted therapy versus switchers (P = 0.03). The main reason physicians gave for switching patients at this stage was worsening condition (46.6%).ConclusionsMost patients were prescribed a TNFi as their first targeted therapy; over half then cycled to another TNFi. This suggests other factors may influence second use targeted treatment choice and highlights the need for greater understanding of outcomes associated with subsequent treatment choices and potential benefits of switching.

Project description:OBJECTIVES:To determine whether patients with early rheumatoid arthritis (ERA) have cardiovascular disease (CVD) that is modifiable with disease-modifying antirheumatic drug (DMARD) therapy, comparing first-line etanercept (ETN) + methotrexate (MTX) with MTX strategy. METHODS:Patients from a phase IV ERA trial randomised to ETN+MTX or MTX strategy±month 6 escalation to ETN+MTX, and with no CVD and maximum one traditional risk factor underwent cardiovascular magnetic resonance (CMR) at baseline, years 1 and 2. Thirty matched controls underwent CMR. Primary outcome measure was aortic distensibility (AD) between controls and ERA, and baseline to year 1 AD change in ERA. Secondary analyses between and within ERA groups performed. Additional outcome measures included left ventricular (LV) mass and myocardial extracellular volume (ECV). RESULTS:Eighty-one patients recruited. In ERA versus controls, respectively, baseline (geometric mean, 95% CI) AD was significantly lower (3.0×10-3 mm Hg-1 (2.7-3.3) vs 4.4×10-3 mm Hg-1 (3.7-5.2), p<0.001); LV mass significantly lower (78.2 g (74.0-82.7), n=81 vs 92.9 g (84.8-101.7), n=30, p<0.01); and ECV increased (27.1% (26.4-27.9), n=78 vs 24.9% (23.8-26.1), n=30, p<0.01). Across all patients, AD improved significantly from baseline to year 1 (3.0×10-3 mm Hg-1 (2.7-3.4) to 3.6×10-3 mm Hg-1 (3.1-4.1), respectively, p<0.01), maintained at year 2. The improvement in AD did not differ between the two treatment arms and disease activity state (Disease Activity Score with 28 joint count)-erythrocyte sedimentation rate-defined responders versus non-responders. CONCLUSION:We report the first evidence of vascular and myocardial abnormalities in an ERA randomised controlled trial cohort and show improvement with DMARD therapy. The type of DMARD (first-line tumour necrosis factor-inhibitors or MTX) and clinical response to therapy did not affect CVD markers.

Project description:Recent research suggests that rheumatoid arthritis increases the risk of venous thromboembolism. This study compared the risk of venous thromboembolism in patients with newly diagnosed rheumatoid arthritis initiating a biologic disease-modifying antirheumatic drug (DMARD) with those initiating methotrexate or a nonbiologic DMARD.We conducted a population-based cohort study using US insurance claims data (2001-2012). Three mutually exclusive, hierarchical DMARD groups were used: (1) a biologic DMARD with and without nonbiologic DMARDs; (2) methotrexate without a biologic DMARD; or (3) nonbiologic DMARDs without a biologic DMARD or methotrexate. We calculated the incidence rates of venous thromboembolism. Cox proportional hazard models stratified by propensity score (PS) deciles after asymmetric PS trimming were used for 3 pairwise comparisons, controlling for potential confounders at baseline.We identified 29,481 patients with rheumatoid arthritis with 39,647 treatment episodes. From the pairwise comparison after asymmetric PS trimming, the incidence rate of hospitalization for venous thromboembolism per 1000 person-years was 5.5 in biologic DMARD initiators versus 4.4 in nonbiologic DMARD initiators and 4.8 in biologic DMARD initiators versus 3.5 in methotrexate initiators. The PS decile-stratified hazard ratio of venous thromboembolism associated with biologic DMARDs was 1.83 (95% confidence interval [CI], 0.91-3.66) versus nonbiologic DMARDs and 1.39 (95% CI, 0.73-2.63) versus methotrexate. The hazard ratio of venous thromboembolism in biologic DMARD initiators was the highest in the first 180 days versus nonbiologic DMARD initiators (2.48; 95% CI, 1.14-5.39) or methotrexate initiators (1.80; 95% CI, 0.90-3.62).The absolute risk for venous thromboembolism was low in patients with newly diagnosed rheumatoid arthritis. Initiation of a biologic DMARD seems to be associated with an increased short-term risk of hospitalization for venous thromboembolism compared with initiation of a nonbiologic DMARD or methotrexate.

Project description:ObjectiveWe undertook this phase III study to evaluate baricitinib, an orally administered JAK-1/JAK-2 inhibitor, as monotherapy or combined with methotrexate (MTX) compared to MTX monotherapy in patients with active rheumatoid arthritis (RA) who had received no or minimal conventional synthetic disease-modifying antirheumatic drugs (DMARDs) and who were naive to biologic DMARDs.MethodsA total of 588 patients were randomized 4:3:4 to receive MTX monotherapy (once weekly), baricitinib monotherapy (4 mg once daily), or the combination of baricitinib and MTX for 52 weeks. The primary end point assessment was a noninferiority comparison of baricitinib monotherapy to MTX monotherapy based on the proportion of patients meeting the American College of Rheumatology 20% improvement criteria (achieving an ACR20 response) at week 24.ResultsThe study met its primary objective. Moreover, baricitinib monotherapy was found to be superior to MTX monotherapy at week 24, with a higher ACR20 response rate (77% versus 62%; P ≤ 0.01). Similar results were observed for combination therapy. Compared to MTX monotherapy, significant improvements in disease activity and physical function were observed for both baricitinib groups as early as week 1. Radiographic progression was reduced in both baricitinib groups compared to MTX monotherapy; the difference was statistically significant for baricitinib plus MTX. The rates of serious adverse events (AEs) were similar across treatment groups, while rates of some treatment-emergent AEs, including infections, were increased with baricitinib plus MTX. Three deaths were reported, all occurring in the MTX monotherapy group. Malignancies, including nonmelanoma skin cancer, were reported in 1 patient receiving MTX monotherapy, 1 receiving baricitinib monotherapy, and 4 receiving baricitinib plus MTX.ConclusionBaricitinib alone or in combination with MTX demonstrated superior efficacy with acceptable safety compared to MTX monotherapy as initial therapy for patients with active RA.
