Abstract
Objectives: Limited information is available on patients with non-systemic juvenile idiopathic arthritis (nsJIA) receiving biologics in Japan. The types of biologics, treatment duration, prior and concomitant treatments, administration routes (intravenous [IV] or subcutaneous [SC] injection), and patient characteristics were investigated.
Methods: We investigated nsJIA, excluding psoriatic arthritis and ankylosing spondylitis, using data from a Japanese hospital claims database (2008-2024).
Results: Of the 4191 nsJIA patients in the database, 965 (23.0%) received one or more biologics. For the first biologic, the most common were antitumour necrosis factor (anti-TNF) drugs (55.3% overall; adalimumab SC, 32.1%; etanercept SC, 9.8%; infliximab IV, 9.2%; others, < 2.1% each), followed by anti-interleukin-6 (anti-IL-6) drugs (39.9% overall; tocilizumab, 39.1% [IV, 32.4%; SC, 6.6%]; others, ≤ 0.7%), abatacept IV or SC (3.7%), and canakinumab SC (1.0%). Of the patients receiving anti-TNF and anti-IL-6 drugs, 40% and 58% continued treatment for ≥1 year, respectively. The most common conventional synthetic disease-modifying antirheumatic drug (csDMARD) administered prior to anti-TNF and anti-IL-6 drugs was methotrexate [39.0% (anti-TNF) and 33.5% (anti-IL-6)], with others at ≤ 3.6%. The most common csDMARD used concomitantly was also methotrexate [66.9% (anti-TNF) and 50.4% (anti-IL-6)], with others < 8.6%.
Conclusions: Our study describes the real-world usage of biologics for nsJIA in Japan.
