BACKGROUND: Real-world studies assessing the comparative effectiveness of biologic or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) as first-line targeted therapy are scarce. We analyzed the real-world persistence and effectiveness of etanercept (ETN), adalimumab (ADA), and Janus kinase inhibitors (JAKis) as first-line therapy in b/tsDMARD-naïve patients with rheumatoid arthritis (RA).
METHODS: Adults (≥ 18 years) enrolled in the CorEvitas RA Registry and initiating ETN, ADA, or a JAKi (alone or in combination with csDMARDs) between November 2012 and June 2021 were included if they had 6 and/or 12 months' follow-up. Treatment persistence and effectiveness outcomes including the change in Clinical Disease Activity Index (CDAI) and patient-reported outcomes (PROs) were evaluated at follow-up, adjusting for covariates using linear and logistic regression models. An exploratory analysis for patients on monotherapy was also conducted.
RESULTS: Of 1059 ETN, 1327 ADA, and 581 JAKi initiators; 803 ETN, 984 ADA, and 361 JAKi initiators had 6 months' follow-up. JAKi initiators were older and had a relatively longer disease duration than ETN or ADA initiators (mean age: 61.3 vs 54.5 and 55.5 years; mean duration of RA: 8.1 vs 5.7 and 5.6 years). Unadjusted mean improvements in CDAI and PROs were similar between the groups at 6 months, except the proportion achieving LDA, remission, and MCID in CDAI, which were numerically higher in the ETN and ADA groups vs JAKi group (LDA: 43.4% and 41.9% vs 32.5%; remission: 18.2% and 15.1% vs 11.5%; MCID: 46.5% and 47.8% vs 38.0%). Adjusted effectiveness results did not reveal statistically significant differences between treatment groups at 6 months, with an exception in MCID (odds ratio [95% CI] for JAKi vs ETN: 0.65 [0.43-0.98]). At 6 months, 68.2% of ETN, 68.5% of ADA, and 66.5% of JAKi initiators remained on therapy. The findings at 12 months' follow-up and sensitivity analysis among monotherapy initiators also showed no differences in effectiveness outcomes between the groups.
CONCLUSIONS: This analysis of real-world data from the CorEvitas RA Registry did not show differences in clinical effectiveness and treatment persistence rates in b/tsDMARD-naïve patients initiating ETN, ADA, or JAKi as first-line targeted therapy either alone or in combination with csDMARDs.
INTRODUCTION: Etanercept (ETN) has been shown to slow radiographic progression of rheumatoid arthritis (RA) and psoriatic arthritis (PsA) in clinical trials. This real-world, non-interventional study assessed radiographic progression in patients with RA or PsA treated with ETN for ≤ 36 months in outpatient care in Germany (NCT01623752).
METHODS: Patients with RA or PsA attended ≤ 10 visits across two study phases (phase 1: seven visits, baseline to month 18; phase 2: three visits until month 36). Radiographs were taken at baseline (Rx1), months 12-18 (Rx2), and/or months 30-36 (Rx3). Historic radiographs (Rx0) taken 12-48 months pre-baseline were also evaluated (if available). The primary endpoint was the change in modified total Sharp score (mTSS). The erosion score (ES) and joint space narrowing score (JSN) were also evaluated.
RESULTS: Overall, 1821 patients were enrolled (RA: n = 1378; PsA: n = 440). In patients with Rx1 and Rx2 (RA: n = 511; PsA: n = 167), the mean mTSS remained stable for both disease groups, and the annualized median change in mTSS was 0. In patients with Rx0, Rx1, and Rx2 (RA: n = 180; PsA: n = 47), annualized radiographic progression in mTSS, ES, and JSN was larger in the pre-ETN treatment phase than during ETN treatment in both disease groups. The percentage of patients with radiographic non-progression was higher during ETN treatment versus pre-ETN. Improvement in clinical disease activity and patient-reported outcomes was also observed.
CONCLUSIONS: This was the first real-world, non-interventional study to report systematically collected radiographic data in a large cohort of patients with RA or PsA under treatment with a biologic. In patients with available radiographic data, mean radiographic progression was lower and the proportion of patients without progression was greater during ETN treatment than in the pre-ETN period.
OBJECTIVE: To evaluate the impact of methotrexate (MTX) dosage on clinical, functional and quality of life outcomes in patients with rheumatoid arthritis (RA) from two previous etanercept (ETN) trials after 24 months of treatment.
METHODS: Patients with active RA in the ETN+MTX combination treatment arms of the Trial of Etanercept and Methotrexate with Radiographic Patient Outcomes (TEMPO) and COmbination of Methotrexate and ETanercept in Active Early Rheumatoid Arthritis (COMET) studies were pooled in this post hoc analysis and stratified by MTX dosage at 24 months, having MTX monotherapy groups as control: low dose, <10.0 mg/week; medium dose, 10.0-17.5 mg/week; and high dose, >17.5 mg/week. Data from these patient subgroups were included in descriptive summaries of demographic and disease characteristics at baseline. The following outcomes at 24 months were also evaluated for each subgroup: Disease Activity Score in 28 joints (DAS28) low disease activity (LDA) and remission; American College of Rheumatology 20%, 50% and 70% improvement criteria (ACR20, 50 and 70) responses; and changes from baseline in DAS28, Health Assessment Questionnaire Disease Index (HAQ-DI) and EuroQol 5-dimensions visual analogue scale (EQ-5D VAS).
RESULTS: Baseline demographics were similar between the low, medium and high MTX dose groups in the ETN+MTX combination and MTX monotherapy arms, with the exception of disease duration (ETN+MTX low 5.5; medium 5.1; high 0.8 years vs MTX low 8.3; medium 4.7; high 0.8 years). Responses to ETN+MTX combination therapy at 24 months were consistently high across MTX dosage groups, with very similar rates of DAS28 LDA/remission and ACR20/50/70. Improvements in DAS28, HAQ-DI and EQ-5D VAS were also not dependent on MTX dosage in the combination treatment arm.
CONCLUSIONS: Patients with RA in the TEMPO and COMET trials who received ETN+MTX showed similar efficacy outcomes at 24 months, regardless of MTX dosage.
