To explore the novel combination of sirolimus and mycophenolate mofetil (MMF) as graft-vs-host disease (GvHD) prevention in human leukocyte antigen (HLA)-matched related donor peripheral blood stem cell (PBSC) or marrow transplantation (BMT), collectively hematopoietic stem cell transplantation (HSCT). This study will report the toxicities associated with this drug combination.~For all treatments and procedures, Study Day is based on the day of HSCT as Day 0.
A continuation study of sirolimus and mycophenolate mofetil (MMF) for graft-vs-host disease (GvHD) prophylaxis for patients undergoing matched related allogeneic hematopoietic stem cell transplantation (HSCT) for acute and chronic leukemia, myelodysplastic syndrome (MDS), high risk non-Hodgkin lymphoma (NHL), or Hodgkin lymphoma (HL)
