Clinical trial: 3 patients in the non-GVHD group and 3 patients in the GVHD group received FK/MMF/mini-dose MTX on a clinical trial; 2 patients in the non-GVHD group received FK/MTX/bortezomib on the BMT CTN 1203 trial, and 1 patient in the GVHD group received FK/MTX/maraviroc on the BMT CTN 1203 trial.
