Eligibility Criteria

Age 18+ · All Participants · 8 Total Inclusion Criteria

Mark “yes” if the following statements are true for you:
or total cumulative dose of 60 mg If someone takes more than 60 mg of methylprednisolone in 3 days or less, they are likely to experience new organ involvement.
There was no improvement after seven days of primary treatment with methylprednisolone (or equivalent) of greater than or equal to 2mg/kg/day.
Patients who began treatment with methylprednisolone (or equivalent) and had improvement in skin GVHD but not visceral GVHD after seven days were given a greater than or equal to 2mg/kg/day dose.
After myeloid engraftment is confirmed, patients may receive growth factor supplementation.
The patient or someone else who is not involved in their care (in case the patient is not capable of providing verbal consent but capable of signing the ICF) should have given written consent.
Patients who have skin GVHD and develop visceral aGVHD during treatment with methylprednisolone (or equivalent) of greater than or equal to 1mg/kg/day and do not improve after 3 days of greater than or equal to 2mg/kg/day are considered to have organ improvement or progression.
