What was measured

Percentage of patients without radiographic progression at Week 52, defined as change in total modified Sharp score (TMSS) \<= 0. TMSS is the sum of the erosion score (ES) and the joint space narrowing (JSN) score and has a range of 0 to 398. The ES is the sum of joint scores collected for 46 joints and has a range of 0 to 230. The JSN is the sum of joint scores collected for 42 joints and has a range of 0 to 168. A score of 0 would indicate no change.

Analysis population: Modified intent-to-treat population includes patients with a screening and at least one post-baseline radiographic evaluation, grouped as randomized. Patients with missing data are classified as progressing.

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
