<jats:title>Abstract</jats:title><jats:sec><jats:title>Objective</jats:title><jats:p>To compare the benefits of initiating treatment with methotrexate (MTX) and infliximab (anti–tumor necrosis factor α [anti‐TNFα] monoclonal antibody) with those of MTX treatment alone in patients with rheumatoid arthritis (RA) of ≤3 years' duration.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>RA patients were eligible if they had active disease and no prior treatment with MTX or a TNFα inhibitor. One thousand forty‐nine patients were randomly assigned in a 4:5:5 ratio to 3 treatment groups: MTX–placebo, MTX–3 mg/kg infliximab, and MTX–6 mg/kg infliximab. MTX dosages were rapidly escalated to 20 mg/week, and infliximab or placebo infusions were given at weeks 0, 2, and 6, and every 8 weeks thereafter through week 46.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>At week 54, the median percentage of American College of Rheumatology improvement (ACR‐N) was higher for the MTX–3 mg/kg infliximab and MTX–6 mg/kg infliximab groups than for the MTX–placebo group (38.9% and 46.7% versus 26.4%, respectively; <jats:italic>P</jats:italic> < 0.001 for both comparisons). Patients in the MTX–3 mg/kg infliximab and MTX–6 mg/kg infliximab groups also showed less radiographic progression than those receiving MTX alone (mean ± SD changes in van der Heijde modification of the total Sharp score at week 54: 0.4 ± 5.8 and 0.5 ± 5.6 versus 3.7 ± 9.6, respectively; <jats:italic>P</jats:italic> < 0.001 for each comparison). In addition, physical function improved significantly more in the MTX–3 mg/kg infliximab and MTX–6 mg/kg infliximab groups than in the MTX–placebo group. Infliximab therapy was associated with a significantly higher incidence of serious infections, especially pneumonia.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>For patients with active RA in its early stages, combination therapy with MTX and infliximab provides greater clinical, radiographic, and functional benefits than treatment with MTX alone.</jats:p></jats:sec>
