Overview
Brief Summary
This open-label single arm study will evaluate the efficacy and safety of tocilizumab added to traditional disease-modifying antirheumatic drugs (DMARDs) in patients with moderate to severe active rheumatoid arthritis and an inadequate response to DMARDs. Patients will receive tocilizumab 8 mg/kg by intravenous infusion every 4 weeks for 24 weeks, in addition to their current non-biologic DMARDs at stable doses. Anticipated time on study treatment is 24 weeks, and the target sample size is 200.

Outcomes
Primary Outcomes
Health Assessment Questionnaire (HAQ) Score
Time Frame: Weeks 0, 4, 8, 12, 16, 20, and 24 and Withdrawal Visit
HAQ includes 20 questions concerning participant's activities of daily life, grouped in 8 scales of 2 to 3 questions for each activity. To respond to each question, a four-level response (score of 0 to 3 points), with higher scores showing larger functional limitations, was chosen. Scoring was as follows with respect to performance of participant's everyday activities: 0 (equals)=without difficulties; 1=with some difficulties; 2=with great difficulties; and 3=unable to perform these actions at all. Minimum score was 0, maximum score was 3. Withdrawal Visit is the final visit prior to the withdrawal of the subject from the study.
Percentage of Participants With an HAQ Score Decrease of 20 Percent (%), 50%, and 70% During Tocilizumab Treatment
Time Frame: Weeks 4, 8, 12, 16, 20, and 24
HAQ includes 20 questions concerning participant's activities of daily life, grouped in 8 scales of 2 to 3 questions for each activity. To respond to each question, a four-level response (score of 0 to 3 points), with higher scores showing larger functional limitations, was chosen. Scoring was as follows with respect to performance of participant's everyday activities: 0=without difficulties; 1=with some difficulties; 2=with great difficulties; and 3=unable to perform these actions at all. Minimum score was 0, maximum score was 3.
Change in HAQ Score at Week 24
Time Frame: Baseline and Week 24
HAQ includes 20 questions concerning participant's activities of daily life, grouped in 8 scales of 2 to 3 questions for each activity. To respond to each question, a four-level response (score of 0 to 3 points), with higher scores showing larger functional limitations, was chosen. Scoring was as follows with respect to performance of participant's everyday activities: 0=without difficulties; 1=with some difficulties; 2=with great difficulties; and 3=unable to perform these actions at all. Minimum score was 0, maximum score was 3.
