Abstract

Objective: Two randomised controlled trials, AMBITION (NCT00109408) and ADACTA (NCT01119859), showed tocilizumab (TCZ) monotherapy superior to methotrexate (MTX) and adalimumab (ADA) monotherapy, respectively, for improving rheumatoid arthritis (RA) disease activity. This study compared the benefit of TCZ versus MTX or ADA monotherapy for improving patient-reported outcomes (PROs) in patients with RA.Methods: PROs included patient global assessment (PtGA), pain, Health Assessment Questionnaire Disability Index (HAQ-DI), Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue and Short Form-36 (SF-36) physical component summary (PCS) and mental component summary (MCS) and eight domain scores. Outcomes included proportions of patients reporting changes from baseline in PRO scores ≥minimum clinically important differences (MCID) and ≥age-matched and gender-matched normative values at 24 weeks.Results: In AMBITION, TCZ-treated patients reported significantly greater mean improvements in HAQ (-0.7 vs -0.5), FACIT-Fatigue (8.7 vs 5.7), SF-36 PCS (9.8 vs 7.8) and five SF-36 domains at week 24 than with MTX; 45.0%-84.0% of TCZ-treated patients reported improvements ≥MCID, and 24.3%-52.1% reported scores ≥normative values across all PROs versus 39.4%-81.8% and 14.5%-45.0%, respectively, with MTX. In ADACTA, TCZ-treated patients reported significantly greater improvements in PtGA (-42.3 vs -31.8), pain (-40.1 vs -28.7), SF-36 MCS (7.9 vs 5.0) and three SF-36 domains than with ADA; 57.7%-83.3% of TCZ-treated patients reported improvements ≥MCID, and 22.1%-49.3% reported scores ≥normative values across all PROs versus 13.6%-37.8%, respectively, with ADA.Conclusions: TCZ monotherapy resulted in more patients reporting clinically meaningful PRO improvements and PRO scores ≥normative values compared with MTX or ADA monotherapy.
