Evidence summary

IL-1 receptor antagonist that blocks both IL-1α and IL-1β signalling. Despite TRAPS being a TNF receptor disease, IL-1 blockade is the most effective treatment because the pathogenic cascade converges on IL-1β via mitochondrial ROS and NLRP3 activation. Eurofever data shows ~90% efficacy with ~67% complete remission. Can be used on-demand for milder cases or continuously for severe disease.
