Itacitinib for Low Risk GVHD

Patients with newly diagnosed low risk acute GVHD defined as Minnesota standard risk based on symptoms and Ann Arbor 1 GVHD based on biomarkers were eligible if they met all other eligible criteria (see eligibility criteria below). Enrolled patients were required to start treatment within 4 days of confirmation of Ann Arbor 1 status. Treatment consisted of itacitinib 200 mg daily for 28 days. Patients with a clinical response on day 28 were eligible for a second 28 day cycle of itacitinib 200 mg daily. Missed doses could be made up by extending the treatment duration for up to 2 additional weeks. Medications given for GVHD prophylaxis and topical treatments for GVHD were allowed. Supportive care was provided according to institutional standards. Itacitinib was permanently discontinued after any of the following: administration of 56 doses of itacitinib or initiation of systemic corticosteroids or any other systemic treatment for GVHD or patient withdrawal from the study or general or specific changes in the patient's condition render the patient unacceptable for further treatment in the judgment of the investigator OR ten weeks elapsed since the first dose of itacitinib.
