Repeat Transplantation for Relapsed or Refractory Hematologic Malignancies Following Prior Transplantation

April 24, 2017 updated by: St. Jude Children's Research Hospital

CD45A-Depleted Haploidentical Hematopoietic Progenitor Cell and Natural Killer Cell Transplantation for Hematologic Malignancies Relapsed or Refractory Despite Prior Transplantation

This pilot phase II trial studies how well a new reduced intensity conditioning regimen that includes haploidentical donor NK cells followed by the infusion of selectively T-cell depleted progenitor cell grafts work in treating younger patients with hematologic malignancies that have returned after or did not respond to treatment with a prior transplant. Giving chemotherapy and natural killer cells before a donor progenitor cell transplant may help stop the growth of cells in the bone marrow, including normal blood-forming cells (progenitor cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's cells. When the healthy progenitor cells from a related donor are infused into the patient they make red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Removing specific T cells from the donor cells before the transplant may prevent this.

Study Overview

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.

Measure Description
Time Frame

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.
