Abstract
Objectives: To assess dosing, preliminary safety, and efficacy of canakinumab, a fully human anti-interleukin-1β (IL-1β) antibody, in children with systemic juvenile idiopathic arthritis (sJIA) and active systemic features.
Methods: In this open-label, dose-escalation, phase II study, children with sJIA who were ≥ 4 years of age, with fever, and receiving ≤ 0.4 mg/kg/d of corticosteroids, were administered a single subcutaneous (sc) dose of canakinumab, 0.5–9 mg/kg and were re-dosed upon relapse. Response was assessed according to adapted American College of Rheumatology (ACR) pediatric criteria.
Results: 23 Children (aged 4–19 years) with active disease were enrolled; 1 patient was excluded and 3 re-enrolled patients were included twice in the efficacy analysis. By day 15 of the first treatment cycle, 15/25 (60%) of patients achieved an adapted ACR ped 50 with 4 of them achieving inactive disease status. Response was sustained over time with 11/13 patients able to maintain response throughout the study. 8/11 Responders receiving steroids at baseline decreased their steroid dose from 0.38 to 0.13mg/kg/day over the first 5 months, with 4 patients able to discontinue. At a dose of canakinumab 4 mg/kg sc every 4 weeks, the median percentage of patients predicted to relapse within 4 weeks was estimated to be 6% (95% confidence interval, 1% to 21%). Therapy was generally well tolerated and few patients experienced injection-site reactions.
Conclusions: Canakinumab has a promising preliminary safety and efficacy profile in this limited cohort. This trial warrants further studies in a larger population of children with sJIA.
