Title: Pediatric Rheumatology – Clinical and Therapeutic Aspects II: Juvenile Arthritis

Session Type: ACR Concurrent Abstract Session

Session Time: 2:30PM-4:00PM

Background/Purpose:   The management of SJIA with biological therapies is aimed to achieve and maintain clinical remission (CR), and accordingly taper corticosteroids (CS). Canakinumab (CAN) demonstrated high inactive disease (ID) rates in about 33% of patients (pts) in Day 15 and 30 respectively in previous studies1. However, little is known about high level response rates in SJIA pts using CAN long-term. The objective of this study was to evaluate the long-term treatment response in terms of safety and efficacy in CAN treated pts with active SJIA.

Methods:   This was an open-label, non-comparative study of CAN-naïve SJIA pts (≥2 to <20 years) receiving subcutaneous CAN 4 mg/kg every 4 weeks. Efficacy was assessed every 3 months by the aACR (30/50/70/90/100) responses compared to baseline (BL), ID or CR (ID for >6 months) and changes in JADAS10-CRP scores over time. Safety was assessed by adverse events (AEs) and serious AEs (SAEs).The results are based on the observed data with imputations to carry the last observation forward.

Results:   Of 123 pts with active SJIA, 70 (57%) had fever and 71 (57.7%) used corticosteroids at BL. Mean CRP was 117.8 mg/L (normal: 0-10 mg/L), and, on average, pts had 9.9 active joints and 8.9 joints with limited motion. A rapid response was observed at Day 15: 59 (51%) and 27 (26%) pts had aACR ≥70 and aACR 100 responses, respectively. These responses were maintained at subsequent time points (Table). At Month 6, CR was achieved in 52 (42.3%) pts. Overall, 33 (26.8%) pts had CR for at least 12 months. At BL, the median CRP score was 22.3, with median changes from BL of −12.0 at Day 15 and −16.8 at last assessment, respectively. At the last assessment, 59 (48.4%) pts had ID (JADAS10 ≤1); 14 (11.5%) had low disease activity (JADAS10 >1 and ≤3.8), while 14 (11.5%) had moderate and 35 (28.7%) had high disease activity. Overall, 24 (33.8%) pts were steroid-free at last assessment. In total, 108 (87.8%) pts had at least 1 AE. Overall, exposure adjusted AE and SAE rate was 8.22 and 54.8 events/pt-years (pyr) respectively, with 183.56 pyr exposure and 40 (32.5%) pts had SAEs; most commonly reported SAEs were disease flares or worsening of SJIA in 13 (10.6%) pts, macrophage activation syndrome in 6 (4.9%) pts, and fever in 4 (3.3%) pts. No deaths occurred in this study.

Conclusion:   CAN treatment was associated with rapid response and sustained therapeutic effect over the long-term in the pts with active SJIA. The safety profile is consistent with other CAN studies. References: 1. Ruperto et al. N Engl J Med. 2012;367:2396-406.
