  11. Incidence of cGvHD [ Time Frame: 2 years ]
    cGvHD is defined as the diagnosis of any cGvHD including mild, moderate, severe

  12. Monitoring of donor cell chimerism [ Time Frame: 2 years ]

    To assess pharmacokinetic/pharmacodynamics relationship (comparison of Cmax with safety)

  18. PK parameter: Ctrough versus efficacy [ Time Frame: 24 weeks ]
    To assess pharmacokinetic/pharmacodynamics relationship (comparison of Ctrough with efficacy)

Criteria

Inclusion Criteria:

  • Male or female patients age ≥28 days and <18 years at the time of informed consent.
  • Patients who have undergone alloSCT from any donor source (matched unrelated donor, sibling, haplo-identical) using bone marrow, peripheral blood stem cells, or cord blood. Recipients of myeloablative or reduced intensity conditioning are eligible.
  • Patients with a clinically confirmed diagnosis of grades II-IV aGvHD within 48 hours prior to study treatment start. Patients may have either: Treatment-naïve aGvHD (criteria per Harris et al. 2016) OR Steroid refractory aGvHD as per institutional criteria, or per physician decision in case institutional criteria are not available, and the patient is currently receiving systemic corticosteroids.
  • Evident myeloid engraftment with ANC > 1,000/µl and platelet count >20,000/µl. (Use of growth factor supplementation and transfusion support is allowed.)

Exclusion Criteria:

  • Has received the following systemic therapy for aGvHD: a) Treatment-naïve aGvHD patients have received any prior systemic treatment of aGvHD except for a maximum 72h of prior systemic corticosteroid therapy of methylprednisolone or equivalent after the onset of acute GvHD. Patients are allowed to have received prior GvHD prophylaxis which is not counted as systemic treatment (as long as the prophylaxis was started prior to the diagnosis of aGvHD); OR b) SR-aGvHD patients have received two or more prior systemic treatments for aGvHD in addition to corticosteroids
  • Clinical presentation resembling de novo chronic GvHD or GvHD overlap syndrome with both acute and chronic GvHD features (as defined by Jagasia et al 2015).
  • Failed prior alloSCT within the past 6 months.
  • Presence of relapsed primary malignancy, or who have been treated for relapse after the alloSCT was performed, or who may require rapid immune suppression withdrawal of immune suppression as pre-emergent treatment of early malignancy relapse.
  • Acute GvHD occurring after non-scheduled donor leukocyte infusion (DLI) administered for pre-emptive treatment of malignancy recurrence. Note: Patients who have received a scheduled DLI as part of their transplant procedure and not for management of malignancy relapse are eligible.
  • Any corticosteroid therapy for indications other than aGvHD at doses > 1 mg/kg/day methylprednisolone (or equivalent prednisone dose 1.25 mg/kg/day) within 7 days of Screening. Routine corticosteroids administered during conditioning or cell infusion is allowed.
  • Patients who received JAK inhibitor therapy for any indication after initiation of current alloSCT conditioning.

Other protocol-defined Inclusion/Exclusion may apply.
