The study enrolled adult and adolescent (≥12 years of age) patients with a diagnosis of recurrent idiopathic or postcardiac injury pericarditis, defined as two or more recurrences after the first pericarditis episode. Eligible patients could be taking any combination of NSAIDs, colchicine or glucocorticoids. Eligible patients were required to have 1 day or more with pericarditis pain severity 4 or greater on an 11-point Numerical Rating Scale and C reactive protein level of at least 1.0 mg/dL within 7 days before first administration of rilonacept. Pericarditis recurrence required these scores for pericarditis signs/symptoms, whereas clinical response required a pericarditis pain severity score of 2 or less with a C reactive protein level ≤0.5 mg/dL.
