Allogeneic Hematopoietic Stem Cell Transplantation for High-Risk Hematologic Malignancies Using One Haploidentical Donor
- Conditions
- Hematopoietic/Lymphoid Cancer
- Interventions
- Radiation: Total-Body Irradiation (TBI)Biological: Donor Lymphocyte Infusion (DLI)Procedure: Allogeneic hematopoietic stem cell transplantation (HSCT)
- Registration Number
- NCT01982682
- Brief Summary
This phase II trial studies how well total-body irradiation, donor lymphocyte infusion, and cyclophosphamide before donor stem cell transplant works in treating patients with high-risk hematologic malignancies. Giving total-body irradiation, donor lymphocyte infusion, and chemotherapy before a donor stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Removing the T cells from the donor cells before transplant and giving tacrolimus and mycophenolate mofetil may stop this from happening.
- Detailed Description
PRIMARY OBJECTIVES:
1) To assess 1 year relapse free survival in high risk patients undergoing hematopoietic stem cell transplant (HSCT) using the Thomas Jefferson University (TJU) 2 step approach with 2 days inserted between the last fraction of total-body irradiation (TBI) and the infusion of donor T cells (donor lymphocyte infusion \[DLI\]).
SECONDARY OBJECTIVES:
1. To assess regimen related toxicity in this updated conditioning regimen, graft-versus-host disease (GVHD) incidence and severity, and overall survival in patients undergoing treatment on this protocol.
2. To assess the consistency and pace of engraftment.
3. To assess the pace of T cell and B cell immune recovery.
OUTLINE:
CONDITIONING REGIMEN: Patients undergo TBI twice daily (BID) on days -10 to -8, undergo DLI on day -6, and receive cyclophosphamide intravenously (IV) over 2 hours on days -3 and -2.
TRANSPLANT: Patients undergo cluster of differentiation (CD) 34+ selected allogeneic HSCT on day 0.
GVHD PROPHYLAXIS: Patients receive tacrolimus IV or orally (PO) beginning on day -1 with taper beginning by day 42, and mycophenolate mofetil IV BID on days -1 to 28.
After completion of study treatment, patients are followed up for 1 year.

This treatment is for patients with high risk hematologic malignancies. High risk is defined as:
- Any patient with a hematologic malignancy with residual disease after treatment with 1 or more chemotherapy regimens in whom achievement of remission with additional chemoradiotherapy is felt to be unlikely
- Patients without morphologic evidence of disease but with high risk features which would predict for relapse despite remission at HSCT such as adverse cytogenetics, 3rd or greater CR (complete response), or failure to recover peripheral blood counts to normal ranges. While these patients do not have detectable disease by current methods, like all patients they have non-detectable disease which in their case is highly aggressive.
-
Patients must have one related donor who is HLA (human leukocyte antigen) mismatched in the GVHD direction at two or more HLA loci

- Primary Outcome Measures
Name Time Method Count of Participants That Experience 1 Year Relapse Free Survival After Undergoing Hematopoietic Stem Cell Transplantation (HSCT) Using the Thomas Jefferson University 2 Step Approach Up to 1 year after HSCT
- Secondary Outcome Measures
Name Time Method Median Pace of T Cell Immune Recovery at 28 Days Post Hematopoietic Stem Cell Transplantation (HSCT) At 28 days post HSCT An excess amount of residual T-lymphocytes in the Peripheral Blood Stem Cell Collection (PBSC) product may increase the risk of GVHD. The ideal amount of T-cells left in the PBSC product is no greater than 5x104/kg. Every effort will be made to keep T-cell amounts to below this threshold. The median pace of T-cell immune recovery at 28 days will be monitored by collecting cluster of differentiation (CD24) and (CD38).
Median Pace of T Cell Immune Recovery at 90 Days Post Hematopoietic Stem Cell Transplantation (HSCT) 90 days post HSCT An excess amount of residual T-lymphocytes in the Peripheral Blood Stem Cell Collection (PBSC) product may increase the risk of GVHD. The ideal amount of T-cells left in the PBSC product is no greater than 5x104/kg. Every effort will be made to keep T-cell amounts to below this threshold. The median pace of T-cell immune recovery at 90 days will be monitored by collecting cluster of differentiation (CD24) and (CD38).
Count of Participants That Experienced Death as a Result of Graft-versus-host Disease (GVHD) Up to 1 year after HSCT Graft versus host disease was clinically characterized based on 4 stages of progression for three major body areas, skin, liver, gut. Subjects who experienced life threatening reactions in their skin, liver and gut ultimately experienced functional impairment and expired.
Life threatening reactions in the Skin were characterized by desquamation (the shedding of the outer layers of skin) and bullae (a bubblelike cavity filled with air or fluid, in particular).
Life threatening reactions in the Liver were characterized by Bilirubin, \> 15 mg/dl Life threatening reactions in the Gut were characterized by Pain +/- ileus (a painful obstruction of the ileum or other part of the intestine.)Number of Participants With Successful Engraftment Up to 1 year after HSCT Will be reported descriptively. Successful engraftment is defined as ANC (absolute neutrophil count, the number of white blood cells (WBCs) that are neutrophils) ≥ 0.5x109/L for at least 30 days and Platelet engraftment \> 20,000 with no transfusion x 7 days.
