Participant Flow

A study of itacitinib in combination with corticosteroids for the treatment of Grades II to IV acute graft-versus-host disease (aGVHD) in pediatric participants 28 days to \< 18 years old who were naïve to corticosteroids. The study was conducted from 31-Dec-2019 to 17-Feb-2020.

A total of 2 participants were screened and included in the study.
