Number of Participants With a Complete Response Primary · 3 years

The endpoint of this study is complete response, defined as the clearance of the CMV infection 3-7 weeks following completion of the last cycle of CMV CTLs. The evaluation of treatment efficacy will be assessed separately for patients receiving CMV specific T cells from their transplant donor.

Sponsor's own description

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.
