Umbilical Cord Transplantation for the Elderly Population

August 19, 2019 updated by: Patrick Stiff, Loyola University
While cord blood transplants have been performed safely in elderly patients, many still relapse. The investigators propose to intensify the preparative regimen for this patient group in an attempt to decrease relapses, and combine this with an ex vivo expanded Umbilical Cord Blood (UCB) unit.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Allogeneic stem cell transplantation is a life saving procedure in selected high-risk or recurrent hematologic malignancies and marrow failure syndromes. However its wide application is limited by availability of suitably HLA matched adult donors. Umbilical Cord Blood (UCB) has been increasingly used as an alternative hematopoietic stem cell source for these patients. To date, over 10,000 UCB transplants have been performed in both children32-38 and adults.35,39-44 Its advantages include easier procurement, decreased risk to donors, reduced risk of transmitting infections, the immediate availability of cryopreserved units, and acceptable HLA mismatches. The transplantation of UCB allows a greater degree of HLA mismatching without an unacceptably high incidence of graft versus host disease (GVHD). Adult patients receiving myeloablative cord blood transplants have a 90% chance of engraftment, but carry a 50% rate of transplant related mortality.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Unmanipulated arm
Participants that do not meet criteria for StemEx®, will be registered into the unmanipulated UCB arm and receive the standard conditioning regimen.
Experimental: Stemx Arm
StemEx is a stem/progenitor cell-based product of ex-vivo expanded allogeneic UCB, which is administered to the subject in combination with the non-manipulated portion of the same cord blood unit (CBU). The CBU must be cryopreserved in two portions of which the larger (or equal) CBU portion contains at least 1.5 x 107 total nucleated cells (TNC)/Kg. This portion remains unmanipulated and is transplanted on Day 0. StemEx is derived from the smaller (or equal) CBU portion, which is expanded ex vivo for 21 days starting pre-transplant in the presence of cytokines TPO, IL-6, Flt-3L and SCF at a concentration of 50ng/ml and 5μM tetraethylenepentamine (TEPA)
Biological: StemEx

For patients allocated to StemEx® arm:

  • Day -20: Start small (or equal) portion expansion at processing site. (II) Conditioning Phase
  • Day -6 to -1: Subject receives a RIC regimen containing Fludarabine, Cyclophosphamide and Total Body Irradiation (TBI) (III) Transplantation and Follow-up Phase
  • Day 0: CBU unmanipulated portion transplantation (for StemEx® arm) or unmanipulated CBU transplantation.
  • Day 1: StemEx® transplantation.
  • Day 2 to 3 years: Post transplant follow-up.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Efficacy of StemEx
Time Frame: 100 days
The primary endpoint is to demonstrate the efficacy of StemEx® vs. unmanipulated UCB transplantation in the elderly population (>55years of age) following RIC regimen by demonstrating engraftment with full donor chimerism (>98%) by Day 100 of more than 60% of the patients who received transplants expanded by the StemEx method.
100 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time to engraftment
Time Frame: 42 days
The day of neutrophil engraftment is defined as the first day of 3 consecutive days of an ANC greater than 500/microliter. The platelet recovery is the first of 3 consecutive measurements tested on different days of a platelet count greater than or equal to 20,000 without requiring platelet transfusions in the previous 7 days. Patients will be monitored for donor cell engraftment as evidenced by neutrophil recovery and donor chimerism in the marrow and/or peripheral blood at serial time points post transplant.
