Differences Between Patients Randomized to MMF-30 (Control Cohort) and MMF-15 (Investigational Cohort) Diagnosed With Chronic Graft vs Host Disease (GVHD)

Arm I (MMF-15, Sargramostim)

Patients receive mycophenolate mofetil (MMF) PO or IV BID on days 0-15 and sargramostim SC from post-transplant day 4 until neutrophil engraftment. mycophenolate mofetil: Given PO, by mouth, orally or IV, intravenous medication administration. Sargramostim: GM-CSF beginning post-transplant day 4 and continuing until hematopoietic reconstitution. Patients in the MMF-15 cohort will receive sargramostim (GM-CSF) 250 mcg/m2/day beginning on post-transplant day 4 and continuing until neutrophil engraftment. Patients receiving GM-CSF will also receive inhaled corticosteroids, fluticasone (Flovent) 2 puffs twice daily, starting on post-transplant day 4 and stopping after cessation of GM-CSF, to diminish the risk of pneumonitis. Note: At investigator discretion, patients in the MMF-15 cohort who have preexisting pulmonary risk factors, will be permitted to receive G-CSF.

Arm II (MMF-30, Filgrastim)

Patients receive mycophenolate mofetil PO or IV BID on days 0-30 and filgrastim from post-transplant day 4 until neutrophil engraftment. mycophenolate mofetil: Given PO, by mouth, orally or IV, intravenous medication administration. Filgrastim: G-CSF beginning post-transplant day 4 and continuing until hematopoietic reconstitution. Patients in the MMF-30 cohort will receive filgrastim (G-CSF) 5 mcg/kg/day beginning on post-transplant day 4 and continuing until neutrophil engraftment.
