He receives tacrolimus and low-dose methotrexate as prophylaxis for graft-vs-host disease. One month after blood count recovery, he develops a skin rash despite ongoing tacrolimus therapy. A skin biopsy confirms grade II acute graft-vs-host disease. How should this case be pharmacologically managed at this point?
