Abstract

Abstract : Background: Canakinumab (CAN) leads to improvement for patients (pts) with systemic juvenile idiopathic arthritis (SJIA) 1 . However, little is known about potential differences in response to CAN treatment between pts with vs. without SJIA associated fever at the time of the first CAN administration. Objectives: To evaluate the long-term efficacy and safety profile of CAN-naïve children with SJIA pts with and without SJIA associated fever. Methods: Pts aged 2-20 yrs with SJIA with and without SJIA associated fever at enrollment received open-label CAN 4mg/kg s.c. every 4 wks. Every 3 months, response to CAN was measured by adapted JIA ACR response criteria (aACR/JIA); juvenile arthritis disease activity score [JADAS]; clinical inactive disease; clinical remission on medication [6 months continuous clinical inactive disease]. Safety was assessed monthly. Results: Data on 122/267 pts, 53 (43%) with and 69 (57%) without SJIA associated fever, were available for analysis with a median 94 wk study duration. At Wk4, ∼75% of both subgroups had responded (≥aACR/JIA30), increasing to 90% at Wk12. At Wk2, ∼21% of both subgroups had inactive disease; 44% at Wk8; 60% at Wk20 and then 60-70% for the remainder of the trial. Clinical remission on medication was achieved in about 29% of pts in both subgroups with ∼22% maintaining it for ≥12 consecutive months. At baseline, the median JADAS score was 21.5 with 8 (7.5%) and 99 (92.5%) pts meeting the criteria for moderate (JADAS >3.8 and ≤10.5) and high disease activity (JADAS >10.5), respectively. At Day15, the median JADAS was 6.8 and 1.5 at the last assessment. In addition, at the last assessment, 53 (48%) pts were rated as inactive disease (JADAS ≤1); 10 (9%) with low active disease activity (JADAS >1 and ≤3.8); while 14 (13%) had moderate and 31 (28%) with high disease activity. A similar long-term safety profile to the pivotal program in children with fever at enrollment was observed in these CAN-naïve pts with or without fever. The most common type of adverse event (AE) reported was infection (0.56 infections/100 PT-days) typically involving the upper respiratory tract. Fifteen pts discontinued due to an AE and 40 had >1 SAE (mostly infections, macrophage activation syndrome [MAS], or flare-associated) and no deaths. Eight cases of MAS (0.013 events/100 pt-days) were reported. Conclusions: Canakinumab provides similar efficacy (inactive disease, clinical remission) in SJIA pts with and without SJIA associated fever at treatment onset. The long-term safety profile was acceptable and similar to the pivotal program in SJIA children with fever at enrollment. References: Ruperto et al. N Engl J Med. 2012; 367: 2396-406.
