Objective To report 2‐year patient‐reported outcomes (PROs) from the head‐to‐head Abatacept versus Adalimumab Comparison in Biologic‐Naive RA Subjects with Background Methotrexate (MTX) (AMPLE) trial. Methods AMPLE was a phase IIIb, randomized, investigator‐blinded trial. Biologic‐naive patients with rheumatoid arthritis (RA) and an inadequate response to MTX were randomized to subcutaneous (SC) abatacept (125 mg/week) or adalimumab (40 mg every 2 weeks) with background MTX. PROs (pain, fatigue, ability to perform work, and ability to perform daily activities) were compared up to year 2 for patients in each treatment group, as well as those who achieved low disease activity at both years 1 and 2 (responders) and those who did not (nonresponders). Results A total of 646 patients were randomized and treated with SC abatacept (n = 318) or adalimumab (n = 328). Baseline characteristics were balanced between the 2 treatment arms. Comparable improvements in PROs were observed in the abatacept and adalimumab groups over 2 years, with both groups achieving clinically meaningful improvements in PROs from baseline. At year 2, fatigue improved by 23.4 mm and 21.5 mm on a 100‐mm visual analog scale with abatacept and adalimumab, respectively. Clinical responders achieved greater improvements in PROs than nonresponders. Conclusion In biologic‐naive patients with active RA, despite prior MTX, treatment with SC abatacept or adalimumab with background MTX resulted in comparable improvements in PROs, which were highly correlated with physician‐reported clinical response end points.
