Primary Outcome(s)

Secondary Objective: •To explore the possibility of reducing concomitant steroid treatment
•To determine the long-term efficacy of 8 mg/kg tocilizumab (MRA) with regard to reduction in signs and symptoms

Main Objective: To assess the long-term safety of 8 mg/kg tocilizumab (MRA) as monotherapy or in combination with background DMARD therapy(ies) with regard to adverse events and laboratory result abnormalities.

Primary end point(s): The primary parameters of interest are safety and long-term efficacy.
The following endpoints will be summarized descriptively:
Safety:
• The safety of tocilizumab (MRA) with regard to adverse events and
laboratory result abnormalities.
• Concomitant steroid treatment will be summarized by visit.
• Number of patients who withdraw from treatment.
Efficacy:
• The proportion of patients achieving an ACR20, ACR50 and ACR70
response by visit.
• The proportion of patients who maintain an ACR20, ACR50 or ACR70
response consecutively for 24, 48, 96 and 264 weeks.
• The individual components of the ACR core set will be summarized by
visit.
• Change in Disease Activity Score (DAS28) from baseline to weeks 24,
48, 96 and 264.
• The proportion of patients who are categorical DAS28 responders
(EULAR response) by visit.
• The proportion of patients who remain categorical DAS28 responders
(EULAR response) consecutively for 24, 48, 96 and 264 weeks.
• The proportion of patients who change from monotherapy to
combination treatment by visit.

Timepoint(s) of evaluation of this end point: Safety:

Efficacy:
1. At Week 24 (6 months)
2. At Week 48 (12 months)
3. At Week 96 (24 months)
