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 > or = 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 < or =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.
