Repeat Transplantation for Relapsed or Refractory Hematologic Malignancies Following Prior Transplantation
CD45A-Depleted Haploidentical Hematopoietic Progenitor Cell and Natural Killer Cell Transplantation for Hematologic Malignancies Relapsed or Refractory Despite Prior Transplantation
Study Overview
Status
Conditions
Detailed Description
PRIMARY OBJECTIVE:
- To estimate engraftment by day +42 post-transplant in patients who receive CD45RA-depleted haploidentical donor progenitor cell transplantation following reduced intensity conditioning regimen that includes haploidentical natural killer (NK) cells.
SECONDARY OBJECTIVES:
- Estimate the incidence of malignant relapse, event-free survival, and overall survival at one-year post-transplantation.
- Estimate incidence and severity of acute and chronic (GvHD).
- Estimate the rate of transplant related mortality (TRM) in the first 100 days after transplantation.
Blood progenitor cells will be collected from adult donors to be used for transplantation. Donor cells will be processed and filtered in a laboratory at St. Jude using a machine called the CliniMACS™ device, and later infused (transplanted) into the participant through his/her veins.
Participants undergo a conditioning regimen beginning Day 21 prior to progenitor cell transplantation that includes chemotherapy medications and natural killer cells in preparation for transplantation. They will then receive T-cell depleted HPC transplant followed by CD45RA-depleted HPC transplant the following day.

---|---|---|
Percentage of Participants Engrafted by Day 42 Post-transplant
Time Frame: Day 42 post transplantation
|
To estimate engraftment by day +42 post-transplant in patients who receive CD45RA-depleted haploidentical donor progenitor cell transplantation following reduced intensity conditioning regimen that includes haploidentical NK cells.
Engraftment is defined as the first of 3 consecutive tests performed on different days of an ANC ≥ 500/mm^3 with evidence of donor cell engraftment.

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Incidence of Malignant Relapse
Time Frame: one year post transplantation
|
The estimate of cumulative incidence of relapse will be estimated using Kalbfleisch-Prentice method.
Death is the competing risk event.
The number of participants with incidence of malignant relapse is given.
Relapse was evaluated using standard WHO criteria for each disease.
|
one year post transplantation
|
Event-free Survival (EFS)
Time Frame: one year post transplantation
|
The Kaplan-Meier estimate of event-free survival (EFS) along with their standard errors will be calculated using the SAS macro (bmacro251-Excel2007\kme) available in the Department of Biostatistics at St. Jude, where EFS = min (date of last follow-up, date of relapse, date of graft failure, date of death due to any cause) - date of transplant, and all participants surviving at the time of analysis without events will be censored.
The number of participants who did not experience any of these events through one year post-transplant is given.
|
one year post transplantation
|
Overall Survival (OS)
Time Frame: one year post transplantation
|
The Kaplan-Meier estimate of OS along with their standard errors will be calculated using the SAS macro (bmacro251-Excel2007\kme) available in the Department of Biostatistics at St. Jude, where OS = min (date of last follow-up, date of death) - date of transplant and all participants surviving at the time of analysis without events will be censored.
The number of participants surviving to one-year post-transplantation is given.

Incidence and Severity of Acute GvHD
Time Frame: 100 days post transplantation
|
The cumulative incidence of acute GvHD will be estimated using Kalbfleisch-Prentice method.

The severity of acute GvHD.
The number of participants with incidence by grade is given.
Participants are graded on a scale from 1 to 4, with 1 being mild and 4 being severe.
