Key clinical point: Baricitinib 4 mg may be considered for long-term treatment of patients with moderate to severe rheumatoid arthritis (RA) who were either naïve to disease-modifying antirheumatic drugs (DMARDs) or had inadequate response (IR) to methotrexate (MTX).
Major finding: At week 148, low disease activity was achieved in up to 61% of DMARD-naïve patients and 59% of MTX-IR patients initially treated with baricitinib. Baricitinib was well-tolerated.
Study details: Analysis of data from 2 completed (RA-BEGIN [n = 584] and RA-BEAM [n = 1,305]) and 1 ongoing long-term extension (RA-BEYOND) phase 3 trials involving either DMARD-naïve or MTX-IR patients.
Disclosures: The study was supported by Eli Lilly and Company. L Xie, B Jia, A Elias, A Cardoso, R Ortmann and C Walls are full-time employees of Eli Lilly and Company and may own stock or stock options in the company.
