T-Cell Depletion, Donor Hematopoietic Stem Cell Transplant (HSCT), and T-Cell Infusions in Treating Patients With Hematologic Cancer or Other Diseases

April 18, 2017 updated by: Jaroslaw Maciejewski, The Cleveland Clinic

Phase II Feasibility Study of T-Cell Depletion in Allogeneic Unrelated Bone Marrow Transplantation (MUD ALLO BMT) Followed by Delayed T-Cell Infusions

RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, 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. Removing the T cells from the donor cells before transplant may stop this from happening. Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help destroy any remaining cancer cells (graft-versus-tumor effect).

PURPOSE: This phase II trial is studying T-cell depletion in donor stem cell transplant followed by delayed T cell infusions in treating patients with hematologic cancer or other disease.

Study Overview

Detailed Description

OBJECTIVES:

Primary

  • Determine if T-cell depletion of a peripheral blood progenitor cell (PBPC) graft followed by delayed add-backs of defined doses of donor lymphocytes decreases the rate of graft-versus-host disease and its complications in matched unrelated donor (MUD) allogeneic peripheral blood progenitor cell (PBPC) transplantation in patients with hematologic cancers or other diseases.
  • Determine whether targeted T-cell dosages in the PBPC graft can be achieved in these patients by positive CD34+ selection using the Baxter Inc. Isolex 300i v. 2.5.
  • Determine the effects of T-cell depletion on the rate of engraftment in these patients.
  • Develop a matched unrelated donor (MUD) allogeneic transplantation regimen that will decrease overall treatment-related mortality in these patients.

OUTLINE: This is a non-randomized study.

  • Myeloablative preparative regimen: Patients receive cyclophosphamide IV once daily on days -5 and -4 followed by total body irradiation twice daily on days -3, -2, and -1. Patients also receive tacrolimus on day -1 administered by continuous IV infusion over 24 hours.
  • Peripheral blood progenitor cell graft transplantation: Patients receive T-cell depleted, peripheral blood progenitor cells (PBPC) by IV infusion on day 0. Beginning 1 day after completion of the PBPC infusion, patients receive filgrastim (G-CSF) subcutaneously once daily until blood counts recover.
  • Post transplantation T cell add-backs: Patients receive defined doses of donor T cells by IV infusion on days 45 and 100, in the absence of active graft-versus-host disease (GVHD) requiring steroids*.

NOTE: *A T cell add-back may be given in the presence of GVHD, if the investigator considers the risk from relapse or overwhelming viral infection to outweigh the risk of exacerbating GVHD.

Patients will be followed periodically for relapse and survival.

Experimental: T-Cell Depletion Transplant

Our protocol is designed to attempt to improve the current results of matched unrelated donor (MUD) allo bone marrow transplant (BMT) and will be a major step towards the introduction and refinement of graft engineering. Our approach will address in a rational fashion all major technical and clinical aspects of MUD allo BMT.

Peripheral blood lymphocyte therapy; cyclophosphamide, tacrolimus, peripheral blood stem cell transplantation; total-body irradiation; 'allogeneic hematopoietic stem cell transplantation'

T-cell depletion will be accomplished using CD34 selection with the Baxter Isolex 300i v. 2.5 device. The desirable T-cell dose will be >0.5 x 105 but <1.0 x 105 CD3+ cells per kg. The targeted CD34 cell dose will be >2 x 106 cells/kg.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Treatment-related Mortality (TRM)
Time Frame: 180 days after transplant
The complication rate in matched unrelated donor (MUD) allogeneic bone marrow transplant (allo BMT) is known to be high. Graft failure and severe graft versus host disease (GvHD) are the most significant contributors to treatment related mortality (TRM). This treatment regimen will be considered unacceptable if the number of patients that experience TRM is 55% or greater, and effective if TRM is 33% or less.
