Intervention

Drug:
• Itacitinib
Phase 1: Itacitinib administered orally once daily at the protocol-defined dose according to age cohort, with dose reductions or modifications based on safety assessments. Phase 2: Itacitinib administered orally once daily at the recommended dose from Phase 1.
• Corticosteroids
Phase 1 and 2: Methylprednisolone 2 mg/kg IV daily (or prednisone equivalent) or at a dose that is appropriate for the severity of disease as outlined per local treatment guidelines as background treatment.
