*Complete response was defined as resolution of the baseline flare at day 15 (PGA score <2 plus CRP ≤10 mg/L or a reduction by ≥70% from baseline) and no new flare (PGA score ≥2 and CRP ≥30 mg/L) up to Week 16.1
†Complete response was defined as composite of PGA of autoinflammatory disease activity, and assessment of no or minimal skin disease, and CRP or SAA values <10 mg/L. PGA of disease activity was based on a composite of the following symptoms: urticarial skin rash, arthralgia, myalgia, headache/migraine, conjunctivitis and fatigue/malaise.2
