• * NIH Stage 4 acute GVHD of the skin (i.e., generalized erythroderma with bullous formation) within 7 days prior to Day 1.
• * NIH Stage 2 or higher acute GVHD of the liver function (i.e., bilirubin \>3 mg/dL \[SI: \>51 μmol/L\]) within 7 days prior to Day 1.
• * NIH Stage 2 or higher acute GVHD of the gut (i.e., diarrhea \>556 mL/m2/day for pediatric subjects \[or \>1000 mL/day for young adults as applicable, at centers in the United States only\], or severe abdominal pain with or without ileus) within 7 days prior to Day 1.
