Abstract

Background Efficacy and safety of canakinumab (CAN), a selective, fully human, anti-interleukin-1β monoclonal antibody, in SJIA is supported by the results of 2 phase III trials. In Trial 1 (4-Wk, randomized placebo (PBO)-controlled1) significantly more CAN than PBO group patients (pts) achieved an aACR-Ped30 response. In Trial 2 (open-label CAN-treatment [Part 1] followed by a randomized PBO-controlled withdrawal phase [Part2]1), CAN allowed successful reduction/ discontinuation of steroids and significantly prolonged time to flare, with a safety profile consistent with expectations for a biologic agent1. Although pts with SJIA suffer from a significant impairment in their HRQoL and functioning2, little is known on the effect of CAN on functional ability and HRQoL.

Objectives To report the patient-reported functional ability and HRQoL outcomes from the Phase III program.

Methods In both studies, functional ability was assessed by the Childhood Health Assessment Questionnaire (CHAQ©), HRQoL by Child Health Questionnaire–Parent Form (CHQ-PF50©) for physical ability and psychosocial health status. The CHQ-PF50 is a generic self-administered instrument designed to capture the physical, emotional, and social components of the health status of children. The CHAQ© contains a disability dimension with 20 multiple choice questionnaire concerning difficulty in performing 8 common activities of daily living as well as a parent’s or patient’s assessment of the child overall well-being and pain intensity on VAS (0–100 mm).

Results In Trial 1, improvement from baseline (BL) CHAQ disability index scores for pts treated with a single injection of CAN vs PBO was observed at Day 15 with further improvement at Day 29 and overall, CAN group had an estimated 0.69 improvement vs PBO in the least square mean (LSM) change from BL (p=0.0002) which was ~3.6 x the MCID of -0.193. At Day 29, significant improvements in estimated difference in LSM from BL for VAS pain intensity (-41.86, p<0.0001), and over time in estimated difference in LSM from BL for CHQ-PF50 physical (PhS) (+12.1, p=0.0012) and psychosocial (PsS) (+7.3, p=0.0017) scores were observed for CAN vs PBO. In Trial 2, similar improvements were observed from BL to end of Part 1 with mean improvements of -1.0 in CHAQ disability score, +21.6 for CHQ-PF50 PhS and +9.1 for the CHQ-PF50 PsS, respectively. During Part 2, both CHQ-PF50 scores improved for CAN group (Table).

Conclusions CAN treatment in pts with SJIA resulted in rapid, sustained, and clinically relevant improvements in pts’ HRQoL, pain, and disability with marked improvement observed by Wk 2 of treatment. These results support the meaningful and rapid improvement of SJIA patients with CAN.
