What was measured

The participant's assessment of their current level of pain on a 100 mm horizontal visual analog scale (VAS), where the left-hand extreme of the line (0 mm) was described as "no pain" and the right-hand extreme (100 mm) as "unbearable pain". The percentage change from baseline at each post-baseline visit was calculated as: \[(post-baseline value minus baseline value) divided by Baseline value\]\*100. A negative percentage change from baseline score indicates an improvement.

Analysis population: Intent-to-treat population, LOCF was used. "N" indicates the number of participants with non-missing data at each time point.

Groups in this outcome

Placebo + MTX

Participants received placebo intravenous infusion on Days 1 and 15. From Week 16 onwards, participants could switch to receive rituximab 0.5 g (on Days 1 and 15) every 24 weeks for up to 5 years if they were not in clinical remission and safety criteria were met. Placebo and rituximab infusions were preceded with 100 mg intravenous methylprednisolone. Participants also received a stable dose of 10-25 mg/week of MTX and ≥ 5 mg/week folic acid for the duration of their participation in the study. All participants entered a 48-week safety follow-up (SFU) period following the treatment period.

Rituximab 2 x 0.5 g + MTX

Participants received 0.5 g rituximab administered by intravenous infusion on Days 1 and 15. After Week 24, participants received further courses of rituximab every 24 weeks for up to 5 years if they were not in clinical remission and safety criteria were met. Rituximab infusions were preceded with 100 mg intravenous methylprednisolone. Participants also received a stable dose of 10-25 mg/week of methotrexate and ≥ 5 mg/week folic acid for the duration of their participation in the study. All participants entered a 48-week safety follow-up (SFU) period following the treatment period.

Rituximab 2 x 1.0 g + MTX

Participants received 1.0 g rituximab administered by intravenous infusion on Days 1 and 15. After Week 24, participants received further courses of rituximab every 24 weeks for up to 5 years if they were not in clinical remission and safety criteria were met. Rituximab infusions were preceded with 100 mg intravenous methylprednisolone. Participants also received a stable dose of 10-25 mg/week of methotrexate and ≥ 5 mg/week folic acid for the duration of their participation in the study. All participants entered a 48-week safety follow-up (SFU) period following the treatment period.
