Background Interleukin-1β (IL-1β) is a key driver in the pathogenesis of systemic juvenile idiopathic arthritis (SJIA). Canakinumab (CAN), a selective fully human anti-IL-1β monoclonal antibody, has been shown to be efficacious in the treatment of SJIA.1 Corticosteroids (CS) are a mainstay of therapy for SJIA, however due to the well-known long-term side effects, reduction of CS dosage is desirable.

Objectives To assess patient features that are associated with CS discontinuation with CAN therapy.

Methods As part of the Phase 3 program of CAN, patients (2-19 years of age) with active SJIA received s.c. CAN (4mg/kg to 300 mg max) every four weeks during the maximum 20-week CS-tapering phase.1 CS tapering was to be initiated when at least an adapted ACR50 was achieved and no fever. Here, we present the data specific to CS discontinuation as they pertain to patient baseline features.

Results At baseline 128/177 patients used CS, the median CS dose was 0.27 mg/kg/day (range: 0.02, 1.00). A total of 92/128 (72%) patients using CS at baseline entered the CS-tapering phase, and 57/128 (44.5%; p<0.0001; 90%CI; 37.1, 52.2)1 qualified as CS-tapering successes (primary endpoint). At the end of CS-tapering phase 42 patients were CS-free and 24 had CS dose ≤0.2 mg/kg/day (a secondary endpoint). The 42 patients achieving CS-free status vs. CS users at baseline (n=128) were somewhat older (median age 9 vs. 8 years, and 7/42 [16.7%] vs. 39/128 [30.5%] were <6 years). Additionally, the CS-free patients (n=42) vs. all CS patients (n=128) had at baseline [values are all median (interquartile range)]: fewer joints with active arthritis, 7 (10) vs. 11 (20); lower physician’s global assessment of disease activity, 62 (24) vs. 71.5 (25); limited range of motion (LROM) of 5.5 (10) vs. 10 (25). Conversely, gender, race, and duration of SJIA, CRP, number of flare during the preceding 6 months or specific systemic features (hepatosplenomegaly, lymphadenopathy or serositis) at baseline did not appear to differ between the two groups. Additional information about association of CS-free status and initial CAN response as well other laboratory baseline features will be provided.

Conclusions Canakinumab allowed for successful tapering of CS within 20 weeks in a sizable portion of patients with SJIA and active systemic features requiring CS for disease control. Successful CS discontinuation was more common among somewhat older patients and those with lower physician global ratings, and fewer active and limited joints at baseline.
