The primary outcome measure was clinically inactive disease according to the provisional American College of Rheumatology (ACR) criteria, without glucocorticoids, at 12 months. Secondary outcome measures included Patient\u2010Reported Outcomes Measurement Information System (PROMIS) pain interference and mobility scores, inactive disease as defined by the clinical Juvenile Arthritis Disease Activity Score in 10 joints (JADAS\u201010), and the ACR Pediatric 70 criteria (Pedi 70).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 400 patients enrolled, 257 (64%) began the step\u2010up plan, 100 (25%) the early combination plan, and 43 (11%) the biologic first plan. After propensity score weighting and multiple imputation, clinically inactive disease according to the ACR criteria was achieved in 37% of those on the early combination plan, 32% on the step\u2010up plan, and 24% on the biologic first plan (<jats:italic>P<\/jats:italic> = 0.17). Inactive disease according to the clinical JADAS\u201010 (score \u22642.5) was also achieved in more patients on the early combination plan than the step\u2010up plan (59% versus 43%; <jats:italic>P<\/jats:italic> = 0.03), as was ACR Pedi 70 (81% versus 62%; <jats:italic>P<\/jats:italic> = 0.008), but generalizability was limited by missing data.

Twenty serious adverse events were reported (mostly infections).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Achievement of clinically inactive disease without glucocorticoids did not significantly differ between groups at 12 months.
