High Dose Cyclophosphamide, Tacrolimus, and Mycophenolate Mofetil in Preventing Graft Versus Host Disease in Patients With Hematological Malignancies Undergoing Myeloablative or Reduced Intensity Donor Stem Cell Transplant
A Pilot Study of Post-transplant High Dose Cyclophosphamide (PTCY) as Part of Graft-Versus-Host Disease (GVHD) Prophylaxis in T-Cell Replete HLA-Mismatched Unrelated Donor (MMUD) Ablative and Reduced Intensity Hematopoietic Cell Transplantation (HCT) for Hematological Malignancies

Brief Summary
This pilot phase II trial studies how well high dose cyclophosphamide, tacrolimus, and mycophenolate mofetil work in preventing graft versus host disease in patients with hematological malignancies undergoing myeloablative or reduced intensity donor stem cell transplant. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft versus host disease). Giving high dose cyclophosphamide, tacrolimus, and mycophenolate mofetil after the transplant may stop this from happening.

Outcome Measures
Primary Outcomes (1)
Graft-Versus-Host Disease-Free, Relapse-Free Survival (GRFS) at 1 Year
Estimates will be calculated using the Kaplan-Meier method, Greenwood formula will be used to calculate standard error (SE), and log-log transformation method will be used to construct 95% confidence intervals. Graft versus host disease (GVHD, acute and chronic), disease status and vital status will be monitored per clinical standard operating procedure. For this endpoint failure is defined as the first occurrence of grade 3 or 4 acute GVHD, or moderate/severe chronic GVHD, or disease relapse (for patients in complete remission at the start of conditioning) or disease progression (for patients with active disease at the start of conditioning) or death (from any cause). Patients not experiencing any of these will be censored at his/her date of last contact.
From stem cell infusion to grade 3-4 acute graft versus host disease (GVHD), moderate-severe chronic GVHD, relapse, progression or death (from any cause), whichever occurs first, assessed for up to 1 year.
Secondary Outcomes (2)
Acute Graft Versus Host Disease (aGVHD) of Grades 2-4 According to the Consensus Grading
Up to 100 days post-stem cell infusion
Overall Survival (OS) at 1 Year
From start of transplant to death, or last follow up, whichever occurs first, assessed for up to 1 year.
Study Arms (3)
Regimen A (fludarabine, melphalan, PBSC HCT, GVHD prophylaxis)
EXPERIMENTALPatients receive fludarabine phosphate IV over 60 minutes on days -7 to -3 and melphalan hydrochloride IV over 20 minutes on day -2. Patients undergo PBSC HCT on day 0. Patients receive cyclophosphamide IV over 1-2 hours on days 3-4, mycophenolate mofetil IV or PO TID beginning on days 5 and stopping on day 35 if no severe GVHD is present-35, and tacrolimus IV continuously on days 5-180 with a taper beginning on day 90 in the absence of disease progression or unacceptable toxicity.
Regimen B (fludarabine, busulfan, PBSC HCT, GVHD prophylaxis)
EXPERIMENTALPatients receive fludarabine phosphate IV over 1-3 hours and busulfan IV over 3 hour on days -5 to -2. Patients undergo PBSC HCT on day 0. Patients receive cyclophosphamide IV over 1-2 hours on days 3-4, mycophenolate mofetil IV or PO TID beginning on days 5 and stopping on day 35 if no severe GVHD is present-35, and tacrolimus IV continuously on days 5-180 with a taper beginning on day 90 in the absence of disease progression or unacceptable toxicity.
Regimen C (fludarabine, TBI, PBSC HCT, GVHD prophylaxis)
EXPERIMENTALPatients receive fludarabine phosphate IV over 60 minutes on days -7 to -5 and TBI BID on days -4 to -1. Patients undergo PBSC HCT on day 0. Patients receive cyclophosphamide IV over 1-2 hours on days 3-4, mycophenolate mofetil IV or PO TID beginning on days 5 and stopping on day 35 if no severe GVHD is present-35, and tacrolimus IV continuously on days 5-180 with a taper beginning on day 90 in the absence of disease progression or unacceptable toxicity.
