The interleukin-1 β inhibitor canakinumab has also been FDA-approved for systemic JIA. [39] In the beta-SPECIFIC 1 trial, 84% of patients with SJIA treated with canakinumab experienced at least a 30% improvement in symptoms compared with 10% in the placebo group after 15 days of treatment (P< 0.001). [40]

In the open-label beta-SPECIFIC 2 trial, 45% of canakinumab-treated patients who were prescribed corticosteroids were able to reduce steroid use, and one-third of patients completely discontinued corticosteroids. Additionally, the canakinumab-treated patients were nearly 3 times less likely to experience a new flare, with 74% remaining flare-free compared to 25% with placebo (P = 0.003). [40]
