Donor Peripheral Blood Stem Cell Transplant in Treating Patients With Hematologic Malignancies

Brief Summary
This phase II trial studies how well donor peripheral blood stem cell (PBSC) transplant works in treating patients with hematologic malignancies. Cyclophosphamide when added to tacrolimus and mycophenolate mofetil is safe and effective in preventing severe graft-versus-host disease (GVHD) in most patients with hematologic malignancies undergoing transplantation of bone marrow from half-matched (haploidentical) donors. This approach has extended the transplant option to patients who do not have matched related or unrelated donors, especially for patients from ethnic minority groups. The graft contains cells of the donor's immune system which potentially can recognize and destroy the patient's cancer cells (graft-versus-tumor effect). Rejection of the donor's cells by the patient's own immune system is prevented by giving low doses of chemotherapy (fludarabine phosphate and cyclophosphamide) and total-body irradiation before transplant. Patients can experience low blood cell counts after transplant. Using stem cells and immune cells collected from the donor's circulating blood may result in quicker recovery of blood counts and may be more effective in treating the patient's disease than using bone marrow.

Outcome Measures
Primary Outcomes (4)
Non-relapse Mortality at 1 Year
Cumulative incidence of death without evidence of disease progression at 1 year
Up to 1 year
Percentage of Participants With Chronic Graft Versus Host Disease
Scored according to the National Cancer Institute criteria. Mild-to-severe chronic GVHD at 2 years.
Up to 2 years post-transplant
Incidence of Grades III/IV Acute Graft Versus Host Disease
Grading determined by organ system stages. Grade III/IV acute graft versus host disease is defined as skin: stage IV, liver: stages II-IV, and/or gastrointestinal tract: stages II-IV.
At day 84
Relapse of Malignancy After Transplantation
Defined by either morphological or cytogenetic evidence of acute leukemia consistent with pre-transplant features, or radiologic evidence of lymphoma progression. When in doubt, the diagnosis of recurrent or progressive lymphoma should be documented by tissue biopsy.
Up to 7 years
Secondary Outcomes (8)
Time to Neutrophil Recovery
Up to day 84 post-transplant
Time to Platelet Recovery
Up to day 84 post-transplant
Incidence of Primary Graft Failure
At day 84
Disease-free Survival
3 years from the date of transplant
Toxicity of Treatment Regimen Determined by Number of Adverse Events Per Organ System
Up to day 90
- +3 more secondary outcomes
Study Arms (1)
Treatment (nonmyeloablative HCT, TBI)
EXPERIMENTALPatients receive fludarabine IV over 30-60 minutes daily on days -6 through -2 and cyclophosphamide IV over 1-2 hours on days -6, -5, and 3-4. Patients undergo total-body irradiation on day -1. Patients undergo donor peripheral blood stem cell transplant on day 0. Patients then receive tacrolimus IV once daily or PO BID on days 5-180 (may be continued if active GvHD is present), mycophenolate mofetil IV or PO TID on days 5-35 (may be continued if GvHD present), and filgrastim IV beginning on day 5 until the ANC is \>= 1,000/mm\^3 for three consecutive days.

Eligibility Criteria
You may qualify if:
- Molecular based human leukocyte antigen (HLA) typing will be performed for the HLA-A, -B, -Cw, -DRB1 and -DQB1 loci to the resolution adequate to establish haplo-identity; a minimum match of 5/10 is required; an unrelated donor search is not required for a patient to be eligible for this protocol if the clinical situation dictates an urgent transplant; clinical urgency is defined as 6-8 weeks from referral or low-likelihood of finding a matched, unrelated donor
- Acute leukemias (includes T lymphoblastic lymphoma); remission is defined as \< 5% blasts with no morphological characteristics of acute leukemia (e.g., Auer rods) in a bone marrow with \> 20% cellularity, peripheral blood counts showing ANC \> 1000/ul, including patients in complete remission with incomplete platelet recovery (CRp); if the marrow has \< 20% cellularity due to treatment related cytotoxicity, but still has \< 5% blasts, an exception may be made to include this patient up to principal investigator (PI) discretion
- Acute lymphoblastic leukemia in high risk first complete remission (CR1) as defined by at least one of the following:
- Adverse cytogenetics including but not limited to t(9;22), t(1;19), t(4;11), mixed lineage leukemia (MLL) rearrangements
- White blood cell counts \> 30,000/mcL
- Patients over 30 years of age
- Time to complete remission \> 4 weeks
- Presence of extramedullary disease
- Minimal residual disease
- Other risk factors determined by the patient's attending physician to be high risk features requiring transplantation
- Acute myelogenous leukemia in high risk CR1 as defined by at least one of the following:
- Greater than 1 cycle of induction therapy required to achieve remission
- Preceding myelodysplastic syndrome (MDS)
- Presence of fms-like tyrosine kinase receptor-3 (Flt3) abnormalities
- French-American-British (FAB) M6 or M7 leukemia, or
- +27 more criteria
You may not qualify if:
- HLA-matched or single allele-mismatched donor able to donate
- Pregnancy or breast-feeding
- Current uncontrolled bacterial, viral or fungal infection (currently taking medication with evidence of progression of clinical symptoms or radiologic findings)
- Patients with primary idiopathic myelofibrosis
- DONOR: Positive anti-donor HLA antibody
