BACKGROUND: Etanercept and methotrexate are effective in the treatment of rheumatoid arthritis but no data exist on concurrent initiation or use of the combination compared with either drug alone. We aimed to assess combination treatment with etanercept and methotrexate versus the monotherapies in patients with rheumatoid arthritis. METHODS: In a double-blind, randomised, clinical efficacy, safety, and radiographic study, 686 patients with active rheumatoid arthritis were randomly allocated to treatment with etanercept 25 mg (subcutaneously twice a week), oral methotrexate (up to 20 mg every week), or the combination. Clinical response was assessed by criteria of the American College of Rheumatology (ACR). The primary efficacy endpoint was the numeric index of the ACR response (ACR-N) area under the curve (AUC) over the first 24 weeks. The primary radiographic endpoint was change from baseline to week 52 in total joint damage and was assessed with the modified Sharp score. Analysis was by intention to treat. FINDINGS: Four patients did not receive any drug; thus 682 were studied. ACR-N AUC at 24 weeks was greater for the combination group compared with etanercept alone and methotrexate alone (18.3%-years [95% CI 17.1-19.6] vs 14.7%-years [13.5-16.0], p<0.0001, and 12.2%-years [11.0-13.4], p<0.0001; respectively). The mean difference in ACR-N AUC between combination and methotrexate alone was 6.1 (95% CI 4.5-7.8, p<0.0001) and between etanercept and methotrexate was 2.5 (0.8-4.2, p=0.0034). The combination was more efficacious than methotrexate or etanercept alone in retardation of joint damage (mean total Sharp score -0.54 [95% CI -1.00 to -0.07] vs 2.80 [1.08 to 4.51], p<0.0001, and 0.52 [-0.10 to 1.15], p=0.0006; respectively). The mean difference in total Sharp score between combination and methotrexate alone was -3.34 (95% CI -4.86 to -1.81, p<0.0001) and between etanercept and methotrexate was -27 (-3.81 to -0.74, p=0.0469). The number of patients reporting infections or adverse events was similar in all groups. INTERPRETATION: The combination of etanercept and methotrexate was significantly better in reduction of disease activity, improvement of functional disability, and retardation of radiographic progression compared with methotrexate or etanercept alone. These findings bring us closer to achievement of remission and repair of structural damage in rheumatoid arthritis.

OBJECTIVE: To evaluate different methods of presentation and analysis of radiographic data in a rheumatoid arthritis (RA) randomized controlled trial. METHODS: A double-blind randomized controlled trial including 682 patients with active RA who were treated with methotrexate, etanercept, or a combination of the 2 drugs was used for this study. Probability plots of the change from baseline to year 1 were produced to visualize progression, and were compared with usual descriptive statistics. The primary analysis of the trial (based on annualized actual mean change from baseline in total Sharp score at 1 year, using linear imputation) was challenged using various ways of handling missing information with alternative imputation methods, and by various statistical analyses including analysis of covariance (ANCOVA) and mixed model analysis on both raw and log-transformed data. RESULTS: Probability plots provided detailed insight into the differentiated treatment effects between the 3 arms of this study. As adjuncts to formal hypothesis testing, these plots were more useful for presenting data than were summary descriptive statistics or use of preset cutoff points to define lack of progression. Additional analyses presented here support the results obtained with the per-protocol analysis that showed an advantage of the combination treatment compared with the monotherapy arms and for etanercept versus methotrexate alone. Various ways of handling missing information confirmed the robustness of the results. In addition, both ANCOVA and mixed model analyses on raw and on log-transformed data produced similar results. CONCLUSION: We suggest a panel of alternative analysis methods and alternative ways of handling missing information to verify that the radiographic results reported in an randomized controlled trial are not influenced by technical factors, such as interpolation, handling of missing data, and choice of statistical tests.

OBJECTIVE: To compare patient reported measures of function, health related quality of life (QoL), and satisfaction with medication among patients with rheumatoid arthritis (RA) treated with methotrexate (MTX), etanercept, or both for up to 1 year. METHODS: In a 52 week, double blind, clinical trial, patients with active RA were randomised to receive etanercept 25 mg twice weekly, methotrexate up to 20 mg weekly, or combination therapy. The Health Assessment Questionnaire (HAQ) disability index, EuroQoL health status visual analogue scale (EQ-5D VAS), patient global assessment, and patient general health VAS were administered at baseline and weeks 2, 4, 8, 12, 16, 20, 24, 32, 40, 48, and 52. Satisfaction with the medication was compared at 52 weeks. RESULTS: Of 682 enrolled patients, 522 completed 52 weeks of treatment. Mean improvement from baseline in HAQ score was 0.65, 0.70, and 1.0 for MTX, etanercept, and the combination, respectively. The mean percentage and absolute improvement in the HAQ was significantly higher (p<0.01) for combination therapy than for either of the monotherapies. Combination therapy produced significantly more rapid achievement of HAQ < or =0.5 sustained for 6 months than either of the monotherapies (p<0.01). Compared with patients receiving monotherapy, those receiving combination therapy achieved a significantly better (p<0.05) health state as measured by the EQ-5D VAS (mean (SD) 63.7 (3.2), 66.8 (3.2), 72.7 (3.1) for MTX, etanercept, and the combination, respectively). Results were similar for other assessments (p<0.01). Patients in combination and etanercept groups were significantly more likely (p<0.0001, p = 0.0009, respectively) to report satisfaction with the medication. CONCLUSIONS: Combination therapy with etanercept and methotrexate improved function, QoL, and satisfaction with the medication significantly more than monotherapy.

OBJECTIVE: To evaluate the efficacy, including radiographic changes, and safety of etanercept and methotrexate (MTX), used in combination and alone, in patients with rheumatoid arthritis (RA) in whom previous treatment with a disease-modifying antirheumatic drug other than MTX had failed. METHODS: Patients with RA were treated with etanercept (25 mg subcutaneously twice weekly), oral MTX (up to 20 mg weekly), or combination therapy with etanercept plus MTX through a second year, in a double-blinded manner. Clinical response was assessed using American College of Rheumatology (ACR) criteria and the Disease Activity Score (DAS), in a modified intent-to-treat analysis with the last observation carried forward (LOCF) and in a population of completers. Radiographs of the hands, wrists, and forefeet were scored for erosions and joint space narrowing at annual intervals. RESULTS: A total of 503 of 686 patients continued into year 2 of the study. During the 2 years, significantly fewer patients receiving combination therapy withdrew from the study (29% of the combination therapy group, 39% of the etanercept group, and 48% of the MTX group). Both the LOCF and the completer analyses yielded similar results. The ACR 20% improvement (ACR20), ACR50, and ACR70 responses and the remission rates (based on a DAS of &lt;1.6) were significantly higher with combination therapy than with either monotherapy (P&lt;0.01). Similarly, improvement in disability (based on the Health Assessment Questionnaire) was greater with combination therapy (P&lt;0.01). The combination therapy group showed significantly less radiographic progression than did either group receiving monotherapy (P&lt;0.05); moreover, radiographic progression was significantly lower in the etanercept group compared with the MTX group (P&lt;0.05). For the second consecutive year, overall disease progression in the combination therapy group was negative, with the 95% confidence interval less than zero. Adverse events were similar in the 3 treatment groups. CONCLUSION: Etanercept in combination with MTX reduced disease activity, slowed radiographic progression, and improved function more effectively than did either monotherapy over a 2-year period. No increase in toxicity was associated with combination treatment with etanercept plus MTX.

OBJECTIVE: The Trial of Etanercept and Methotrexate with Radiographic Patient Outcomes (TEMPO) is a 3-year, double-blind, multicenter study evaluating the efficacy and safety of etanercept, methotrexate, and the combination of etanercept plus methotrexate in patients with active rheumatoid arthritis (RA). The results after 1 and 2 years of the study have been previously reported. Here we provide the 3-year clinical and radiographic outcomes and safety of etanercept, methotrexate, and the combination in patients with RA. METHODS: In this randomized, double-blind, multicenter TEMPO study, 682 patients received etanercept 25 mg twice weekly, methotrexate &lt;/=20 mg weekly, or the combination. Key efficacy assessments included the Disease Activity Score (DAS) and the DAS in 28 joints. RESULTS: Combination therapy resulted in significantly greater improvement in the DAS and in more patients with disease in remission than either monotherapy. This finding was confirmed by longitudinal analysis; patients receiving combination therapy were more than twice as likely to have disease in remission than those receiving either monotherapy. Independent predictors of remission included male sex, lower disease activity, lower level of joint destruction, and/or better physical function. Combination and etanercept therapy both resulted in significantly less radiographic progression than did methotrexate (P &lt; 0.05). Etanercept and combination treatment were well tolerated, with no new safety findings. CONCLUSION: Etanercept plus methotrexate showed sustained efficacy through 3 years and remained more effective than either monotherapy, even after adjustment for patient withdrawal. Combination therapy for 3 years led to disease remission and inhibition of radiographic progression, 2 key goals for treatment of patients with RA.

BACKGROUND: Whereas many patients respond quickly to treatment with tumour necrosis factor (TNF) inhibitors, some patients may experience significant but delayed responses. OBJECTIVE: To evaluate the clinical response between 12 and 24 weeks in subjects with rheumatoid arthritis from the Trial of Etanercept and Methotrexate with Radiographic Patient Outcomes. METHODS: Clinical response was assessed at 24 weeks in 12-week non-responders, according to American College of Rheumatology (ACR) response criteria. The proportion of subjects who successfully maintained response to 52 weeks was analysed, as were radiographic outcomes. RESULTS: Data from 682 subjects were included in the analysis. Non and partial responders in all three groups (etanercept, methotrexate and etanercept plus methotrexate) at week 12 showed an improvement in responses at week 24. Over 80% of the week 24 ACR20/50/70 responders in the etanercept plus methotrexate arm sustained their response to 52 weeks. In the etanercept arms, a delayed clinical response was not associated with increased radiographic progression at week 52. CONCLUSION: A significant proportion of non and partial responders to etanercept with or without methotrexate therapy at week 12 achieved a good clinical response or improved their overall clinical response at week 24. Discontinuing TNF inhibitor therapy at 12 weeks may be premature in some rheumatoid arthritis patients.

Objective. This analysis examined clinical and radiographic responses to methotrexate (MTX), etanercept (ETN), and combination ETN and MTX in patients with moderate versus severe rheumatoid arthritis (RA) in both early and late disease. Methods. Data from the Trial of Etanercept and Methotrexate With Radiographic Patient Outcomes (TEMPO) and the Early Rheumatoid Arthritis trials were used. Patients were classified with moderate or severe RA based on Disease Activity Score including 28-joint count (DAS28). Outcomes included DAS28 remission, DAS28 low disease activity, Health Assessment Questionnaire (HAQ), American College of Rheumatology (ACR) scores, Total Sharp Score (TSS) progression, no radiographic progression (annualized change in TSS ≤ 0), change from baseline in TSS, and the change in TSS for patients who had radiographic progression (TSS > 0). Results. Patients with moderate disease generally achieved better clinical outcomes than patients with severe disease, including significant differences in DAS28 remission, low disease activity, and HAQ≤ 0.5 at Month 12. Patients with baseline severe disease had higher ACR and DAS responses than patients with moderate disease. Conclusion. Patients with severe RA disease activity achieved substantial clinical improvement with high-dose MTX and/or ETN treatment, but patients with moderate disease were more likely to reach a lower disease activity state. These findings were independent of disease duration. The results support the opportunity for excellent clinical outcomes, particularly with combination therapy, in patients with moderate RA.
