Reduced Intensity Double Umbilical Cord Blood Transplantation
A Phase II Study of Reduced Intensity Double Umbilical Cord Blood Transplantation Using Fludarabine, Melphalan, and Low Dose Total Body Radiation
This trial will use two cord blood units for transplantation using a reduced intensity regimen rather than using intense doses of chemotherapy and radiation therapy. Two cord blood units (double cord blood) are being used, as the numbers of blood cells in one unit are too few to allow successful growth of these cells.
Because the risk of infection, particularly virus infection, is high after double cord blood transplant, this study seeks to reduce the rise of virus infection by using a reduced intensity regimen without a medicine called antithymocyte globulin (ATG), as used in prior cord blood transplants. Subjects will receive two chemotherapy drugs, melphalan and fludarabine, and low dose of total body radiation (one treatment) instead of the ATG. The number of patients with virus infections in this study will be compared to our prior experience using the ATG.

Ensisijaiset tulostoimenpiteet
Tulosmittaus |
Toimenpiteen kuvaus |
Aikaikkuna |
|---|---|---|
|
Number of Participants With a Clinically Significant Infection
Aikaikkuna: 1 Year
|
The one year significant infection rate (infections requiring medical intervention) after double umbilical cord blood transplant using a novel conditioning regimen of fludarabine/melphalan/low dose total body radiation.
The data is shown as the number of significant infections participants experienced during the first year, measured from the start of treatment.

Toimenpiteen kuvaus |
Aikaikkuna |
|---|---|---|
|
Median Time to Neutrophil Engraftment
Aikaikkuna: From the time of transplantation, until the time of neutrophil engraftment, median duration of 24 days
|
The median number of days measured from the time of transplantation, until the first documented neutrophil engraftment.
neutrophil engraftment is defined as the first of 3 consecutive days of absolute neutrophil count > 500 neutrophils per microliter of blood.
|
From the time of transplantation, until the time of neutrophil engraftment, median duration of 24 days
|
|
Median Time to Platelet Engraftment
Aikaikkuna: From the time of transplantation, until the time of platelet engraftment, median duration of 52 days
|
The time to platelet engraftment is measured from the time of transplantation until the time of first documented platelet engraftment.
Platelet engraftment is defined as a platelet count ≥ 20,000/µL for three consecutive measurements over three or more days.
The first of the three days will be designated the day of platelet engraftment.
Subjects must not have had platelet transfusions during the preceding 3 days or in the following 7 days after the day of engraftment, unless the platelet transfusion is being given specifically to achieve a platelet threshold to allow an elective invasive procedure, such as a central catheter removal.
|
From the time of transplantation, until the time of platelet engraftment, median duration of 52 days
