Maintenance of efficacy of canakinumab in SJIA at the individual patient level in a 12-week pooled dataset
Pediatric Rheumatology volume 12, Article number: P69 (2014)
Recent advances in the management of SJIA considered the induction or maintenance of inactive disease according to the JADAS 10-CRP (J10) or 27-CRP (J27) scoring system [1, 2]. The maintenance of efficacy of canakinumab (CAN), a selective, human, anti-IL-1β monoclonal antibody, was demonstrated in the withdrawal phase of 2 phase III trials , but was not evaluated at the individual level.
To evaluate the maintenance of efficacy at the level of the individual patient from Week 2 to 12, using the adapted ACR-JIA response criteria (aACR) as well as J10 and J27 on the 12-week pooled data set (3 phase III studies).
For this post-hoc analysis of the CAN Phase III program in SJIA, the change in disease states between Day(D) 15 and D85 of a total of 178 CAN-naïve patients was assessed. Subjects were 2–19 years of age and had active SJIA at enrollment. This shift analysis considered the aACR response and certain disease activity states as defined using J10 and J27: Inactive Disease (ID), Low Disease Activity (LDA), Moderate Disease Activity (MDA); High Disease Activity (HDA).
J10 changes during the study period are provided in Table 1. Results for the J27 were very similar to the J10 observations.
The D15-D85 aACR shift analyses, including only patients who had a D15 and a D85 value, likewise indicated that the majority of patients maintained or improved their response: NR (n=32): 12.5% of patients improved; aACR30 (n=14): 0.0% were maintained/78.6% improved; aACR50 (n=21): 33.3% were maintained/42.9% improved; aACR70 (n=36): 25.0% were maintained/58.3% improved; aACR90 (n=26): 30.8% were maintained/57.7% improved; aACR100 (n=34): 82.4% were maintained.
The great majority of CAN patients either maintained or improved their JADAS status or aACR response level from week 2 to 12. These data confirm the consistent maintenance of efficacy of CAN at the individual level in the first 3 months, irrespective of the measure of response, i.e. aACR criteria or JADAS-derived criteria, and extend previous findings at the study group level.
