What was measured

Total Erosion Score is determined by evaluation of fourteen sites in each wrist and hand and six joints in each foot using an eight-point scale from 0 (normal: no erosions) to 3.5 (Very severe; erosions of 100% of the articular surfaces. The Total Erosion Score at Week 24 - Total Erosion Score at baseline is calculated.

Analysis population: Participants from the modified intent-to-treat population (includes patients with a screening and at least one post-baseline radiographic evaluation, grouped as randomized) who had data available at Week 24 for analysis.

Groups in this outcome

Placebo + Methotrexate

Placebo intravenously on Days 1 and 15 + a background of methotrexate orally at a dose of 7.5 mg escalating by 2.5 mg a week every 1-2 weeks to achieve: 15 mg per week by Week 4 and 20 mg per week by Week 8. From Week 104 participants were eligible to receive Rituximab 2 X 0.5 g or Rituximab 2 X 1.0 g every 24 weeks.

Rituximab (0.5 g x 2) + Methotrexate

Rituximab intravenously at a dose of 0.5 g on Days 1 and 15 + a background of methotrexate orally at a dose of 7.5 mg escalating by 2.5 mg a week every 1-2 weeks to achieve: 15 mg per week by Week 4 and 20 mg per week by Week 8. Subsequent Rituximab treatment courses were given at 24 week intervals for 5 years provided the Disease Activity Score 28 Joint Count- Erythrocyte Sedimentation Rate (DAS-ESR) result was ≥2.6

Rituximab (1.0 g x 2) + Methotrexate

Rituximab intravenously at a dose of 1.0 g on Days 1 and 15 + a background of methotrexate orally at a dose of 7.5 mg escalating by 2.5 mg a week every 1-2 weeks to achieve: 15 mg per week by Week 4 and 20 mg per week by Week 8. Subsequent Rituximab treatment courses were given at 24 week intervals for 5 years provided the Disease Activity Score 28 Joint Count- Erythrocyte Sedimentation Rate (DAS-ESR) result was ≥2.6
