Evidence summary

IL-6 is elevated in TRAPS and drives SAA production. Case reports show tocilizumab can control disease when both etanercept and anakinra/canakinumab fail. First reported by Lane et al. 2011 in a patient refractory to prior biologics. Considered for refractory cases, particularly where SAA remains elevated.
