Rilonacept

Rilonacept is an IL-1 R/IL1RacP/Fc fusion protein, which binds to soluble IL-1β, preventing it from binding to its receptor, having a longer half-life as compared with anakinra. Nine children with SOJIA were treated with rilonacept in the open-label phase of a randomized controlled, double-blind study.[39] ACR-Pedi 50 responses were impressive, with 55 and 78% attaining this at the end of 2 and 4 weeks, respectively. In those who had fever, an immediate disappearance of the fever was observed. Tolerability was acceptable. In the long-term open-label phase, outcomes at 24 months were recently presented.[40] Responses were sustained and therapy was generally well tolerated. However, two children developed MAS during therapy with rilonacept. A double-blind, randomized, placebo-controlled trial of rilonacept is ongoing.[102]
