Primary Transplant Donor Derived CMVpp65 Specific T-cells for The Treatment of CMV Infection or Persistent CMV Viremia After Allogeneic Hematopoietic Stem Cell Transplantation

A Phase II Trial of Primary Transplant Donor Derived CMVpp65 Specific T-cells for The Treatment of CMV Infection or Persistent CMV Viremia After Allogeneic Hematopoietic Stem Cell Transplantation

• Status: Completed
• Phase: Phase 2

Summary

The purpose of this study is to see how well transfusions of T-cells work in treating CMV. T-cells are a type of white blood cell that helps protect the body from infection. A transfusion is the process by which blood from one person is transferred to the blood of another. In this case, the T-cells are made from the blood of donors who are immune to CMV. The T-cells are then grown and taught to attack the CMV virus in a lab.

Conditions

• Cytomegalovirus

Interventions

Type	Name	Description
BIOLOGICAL	CMV-pp65 CTLs	Patients will be treated with CMVpp65-CTLs derived from their transplant donor. These will be patients with CMV seropositive transplant donors who have previously provided leukocytes for generation of CMVpp65-CTL and for whom such CMVpp65-CTL are available. The T-cells to be infused will be selected based on criteria mentioned in section 4.0 from our bank of GMP grade CMVpp65-CTL. T-cells will be administered by bolus intravenous infusion. In this phase II trial, patients will be treated at doses of 1 x 106 CMVpp65-CTL/kg/dose/week for 3 weeks. Patients will be observed for the following 3 weeks. Additional 3 week courses of CMVpp65-CTL may be administered if levels of CMV DNA in blood are still detectable despite disease stabilization or improvement.
