Transplantation of Umbilical Cord Blood Following Chemotherapy for Blood Cancers (Cord Blood)

February 14, 2020 updated by: Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins

Transplantation of Expanded and Unexpanded Umbilical Cord Blood Units Following Myeloablative Chemotherapy for Hematologic Malignancies

This study is to evaluate the safety of transplantation of two cord blood products, including toxicities in patients following high-dose, myeloablative chemotherapy for blood malignancies. It is also to determine if the use of two cord products results in an improvement in neutrophil engraftment.

Detailed Description

The success of BMT as a curative option for patients with malignancies is frequently limited by the inability to identify an appropriate donor in time for transplantation.

Transplantations utilizing umbilical cord blood stem cells are increasingly successful. Data suggest that there are fewer and less developed T-cells in cord products when compared to bone marrow and so are likely to produce less graft-vs.-host disease (GVHD) even in the mismatched setting. In addition, the grafts are easily available second to the ease of collection as compared with other sources such as bone marrow and peripheral blood stem cells (PBSCs). The ability to build cord blood repositories containing samples with HLA types from minorities has and will continue to increase the likelihood of finding suitable products for under represented minorities such as African-Americans, Hispanic populations and mixed ethnic populations.

Unfortunately, limitations remain, secondary to the time to engraftment when the cell dose is less than optimal, resulting in delayed or failed engraftment. In addition, increased cell dose appears to be associated with disease free survival. Therefore, this modality of transplant is generally limited to smaller patients. This protocol evaluates the infusion and engraftment of two cord blood products - one that has been expanded ex vivo and one that has not been expanded following myeloablative chemotherapy for the treatment of hematological malignancies.

Primary Objective:

-To evaluate the safety of transplantation of two cord products including an expanded unit including infusional toxicities and potential immunologic competition.

Secondary Objective:

-To determine if the use of two cord products results in an improvement in neutrophil engraftment (ANC>500) in subjects as demonstrated by engraftment <=21 days.

Tertiary Objectives:

Patients will be compared with patients participating in other trials at our institution and to those who receive therapy as per standard of care.

  • To evaluate the rate, extent, and durability of hematopoietic reconstitution and in particular to determine the relative contribution of each cord unit in early engraftment and long-term engraftment
  • To estimate the rate and severity of graft-vs-host disease
  • To estimate the rates of infectious complications
  • To obtain preliminary data regarding disease-free and overall survival
  • To collect samples for future studies of immune reconstitution and for future studies in the laboratory regarding disease and the immune system

We will be able to track the fate of both the unmanipulated and expanded CB progenitors by evaluating differences in the cord products and the recipient by evaluation of sex mismatch, HLA type and/or restriction length polymorphisms (RFLPs). If the expanded CB cells are detected in the patients long-term, this will give us confidence to use expanded CB as the sole hematopoietic progenitor cell support, in future studies.

The major risk is non-engraftment of either one or both of the cord blood units. Non-engraftment of one of the units may lead to prolonged cytopenia and a marked increased risk for infection. Failure of either unit to engraft as defined as failure to detect cells from either cord blood product at Day +60 is likely to result in the death of the subject. There is the possibility of failure of long-term engraftment from both cords. This would be fatal unless an alternative donor option was identified or the unlikely event of autologous reconstitution of bone marrow. There is a possibility of an immune competition of both cord blood products . This could result in the loss of the cord product that would have been responsible for long term engraftment. There is a possibility of the expanded cord product to fail release testing. In this event, only the unexpanded cord would be infused and would likely result in delayed engraftment.

As with all cellular products there are risks associated with the infusion including but not limited to anaphylaxis, transfusion reaction, hemolysis, side-effects of the DMSO that the product is stored in (bradycardia, hypothermia, neurologic changes). The expanded product will be washed however there remains a small chance that a small amount of growth factor remains. The risk associated with these will be allergic.

Experimental: Receive two cord blood units
One cord blood unit will be thawed on day -14 before transplantation and selected using the CliniMACS for primitive cells that express CD133. These cells will be expanded ex vivo for a total of 14 days, using a two-stage procedure. On Day 0 the expanded cells will be harvested, washed three times with CliniMACS buffer (Miltenyi) plus 1% HSA per standard laboratory and clinical practice and the expanded cell product will be infused to a patient who has been prepared with a standard, myeloablative preparative regimen. A second, unexpanded, cord blood product will be infused on Day +1 for safety.
Biological: Ex vivo expansion of cord blood
Day 0: the expanded cell product will be infused to patient; Day +1: A second, unexpanded, cord blood product will be infused
