Brief Summary:

In this trial, we aim to improve the outcomes of haplo cord transplant. Haplo cord transplant is a novel and promising way to improve transplant outcomes. We hypothesize that identification of a graft that is at least 5/6 matched and inherited paternal antigen (IPA) targeted (i.e., cord blood grafts share one or more IPA antigens with the prospective recipient) is more important to the outcome of haplo cord transplant than the nucleated cell dose. The identification of such a graft for a large proportion of the subjects may necessitate accepting a lower umbilical cord graft dose.

In addition to a umbilical cord blood transplant, recipients will receive stem cells from a family member ( a haplo-identical donor) . After collection and prior to infusion, these cells will be purified using a device called a CliniMACS CD34 selection device. The subject will undergo a chemotherapy conditioning regimen prior to transplantation. No experimental drugs are used in this study, and the combinations of drugs that will be used in the conditioning regimen are combinations that have been used in the past.

Detailed Description:

This is a clinical trial for subjects with hematologic malignancies ( acute leukemia, myeloproliferative disorders, lymphoma, myeloma) who are in need of a donor stem cell transplant, and for whom an umbilical cord blood transplant is thought to be the best option. As donors for allogeneic transplant, we typically try to use related family members, such as brothers or sisters, or volunteer donors who are 'HLA matched', i.e. share similar proteins on their cells. This study is for subjects for whom such a matched sibling donor or a matched unrelated donor is not available.

For such subjects a commonly used transplant procedure is to use stem cells from one or two umbilical cords (UCB) from a newborn. These umbilical cord blood grafts, despite not completely matching the recipient, cause few problems with graft vs host disease (a common complication of transplant). But they tend to grow very slowly and subjects often have very prolonged hospital stays and are at high risk for complications due to low blood counts. Umbilical cord blood transplant will be the standard arm for this protocol.

This study uses a new method of bone marrow transplantation called combined haplo-identical cord (haplo-cord) transplantation. In this procedure, cells from a related donor who shares half of the HLA proteins ( haplo-identical) are collected from the blood, as well as cells from an umbilical cord, and then both are transplanted. It is hoped that by using cells from a haplo-identical relative, subjects will have a faster recovery and require fewer transfusions. Over time the haplo-identical cells from the relative are replaced by the cells from the cord blood. The combined transplantation of haplo-identical stem cells and cord blood has previously been used in approximately 60 subjects with very encouraging results.

Traditionally it has been felt that the most important determinant of outcome of an UCB stem cell transplant is the cord blood cell dose. The second determinant is the degree of matching between donor and recipient. Many times, we have difficulty identifying UCB units of sufficient cell dose that are well matched. Of interest,in our prior study of haplo-cord SCT indicated outcomes seemed independent of the UCB cell dose. If this preliminary observation is correct, we may be able to improve the outcomes of haplo cord transplant further by accepting lower threshold UCB doses and rather focusing on optimal matching (including matching for HLA and another characteristic called IPA). This is the primary objective of this study.

Arm Intervention/treatment
Experimental: All Patients

Haplo-cord transplantation:

All subjects will receive a conditioning regimen of chemotherapy prior to stem cell transplantation. No experimental drugs are used in this study, and the combinations of drugs that will be used in the conditioning regimen are combinations that have been used in the past.

For the transplant component of treatment, subject will receive umblical cord blood. The study involves transplantation of unlicensed units of cord blood. Therefore, these are considered investigational products.

In addition to the umbilical cord blood unit, recipients will receive stem cells from a family member ( a haplo-identical donor). After collection and prior to infusion, these cells will be purified using a device called a CliniMACS CD34 selection device.

Device: CliniMACS® CD34 Reagent System
The stem cells from the haplo-identical donor will be purified by a procedure called CD34 selection before they are given to the subject. A special device called the CliniMACS® CD34 Reagent System, which is not FDA approved, will be used for this purpose. The manufacturer of the device, Miltenyi Biotec, is providing the researchers access to the device for use in this research study. Because the stem cells from the haplo-identical donor are treated using the CliniMACS CD34 selection device, they cells are considered investigational.

Drug: Fludarabine
Administer 30 mg/m2 /day intravenously x 5 days (Day -7 to Day -3) of a total dose of 150 mg/m2. Fludarabine will be dosed according to actual body weight.

Drug: Melphalan
Administer 70mg/m2/day intravenously x 2 days. Melphalan will be dosed according to actual body weight. Cryotherapy with ice chips will be administered to prevent mucositis

Drug: Rabbit ATG (rATG)
Administer 1.5 mg/kg/day intravenously x 4 days, total 6 mg/kg. ATG will be dosed according to actual body weight. The first dose will be infused over at least six hours, and subsequent doses over at least 4 hours. Pre-medications include acetaminophen 650 mg by mouth, diphenhydramine 25-50 mg by mouth or intravenously, and methylprednisolone 2 mg/kg (1 mg/ kg at the initiation and 1 mg/kg half-way through anti-thymocyte globulin administration).




Primary Outcome Measures :
  1. Lowest threshold of umbilical cord nucleated cell dose for haplo-cord transplants. [ Time Frame: 100 days ]
    We aim to identify the lowest threshold of umbilical cord nucleated cell dose that can be utilized assure durable umbilical cord blood engraftment in the haplo-cord transplants. The threshold will be defined as the lowest dose which assures cord blood engraftment occurs in at least 80% of subjects.


Secondary Outcome Measures :
  1. Long-term survival of subjects undergoing haplo-cord transplants [ Time Frame: 5 years after transplant ]
    Evaluate the long term outcome of subjects undergoing haplo cord transplants using an optimally matched umbilical cord blood (UCB) graft (i.e. Survival, profession-free survival (PFS), Relapse, transplant-related mortality (TRM), toxicities, infections and GVHD)

  2. Impact of IPA targeting on transplant outcome [ Time Frame: 5 years from transplantation ]
    As much as possible, UCB units will be chosen to be IPA targeted. This is not always possible. We will therefore also retrospectively analyze transplant outcomes and correlate with IPA status.

  3. Impact of NIMA matching on transplant outcome [ Time Frame: 5 years from transplantation ]
    As much as possible, UCB units will be chosen to be NIMA matched. This is not always possible. We will therefore also retrospectively analyze transplant outcomes and correlate with NIMA status.
