AbstractOBJECTIVE: Investigate whether the efficacy and safety of intravenous tocilizumab (TCZ) demonstrated at week 52 in patients with early rheumatoid arthritis (RA) are maintained to week 104. METHODS: Methotrexate (MTX)-naive patients with early progressive RA were randomly assigned to double-blind 4 mg/kg TCZ+MTX, 8 mg/kg TCZ+MTX, 8 mg/kg TCZ+placebo or placebo+MTX for 104 weeks. Patients not receiving 8 mg/kg TCZ and not achieving Disease Activity Score-28 joints (DAS28-erythrocyte sedimentation rate (ESR)) < /=3.2 at week 52 switched to escape therapy (8 mg/kg TCZ+MTX). Analyses were exploratory. RESULTS: Intent-to-treat and safety populations included 1157 and 1153 patients, respectively. DAS28-ESR remission ( < 2.6) rates were maintained from weeks 52 to 104 (eg, 8 mg/kg TCZ+MTX, 49.3% to 47.6%). Placebo+MTX and 4 mg/kg TCZ+MTX escape patients' week 104 response rates were 51.4% and 30.5%, respectively. Inhibition of radiographic progression was maintained with 8 mg/kg TCZ (eg, 8 mg/kg TCZ+MTX mean (SD) change from baseline in modified total Sharp score: 0.13 (1.28), week 52; 0.19 (2.08), week 104). The safety profile of TCZ was consistent with that of previous reports. CONCLUSIONS: Patients with early RA treated with TCZ monotherapy or TCZ+MTX maintained clinical benefits during their second year of treatment with no new safety signals. TRIAL REGISTRATION NUMBER: NCT01007435.
