Trial Outcomes & Findings for Primary Transplant Donor Derived CMVpp65 Specific T-cells for The Treatment of CMV Infection or Persistent CMV Viremia After Allogeneic Hematopoietic Stem Cell Transplantation (NCT NCT01646645)
NCT ID: NCT01646645
Last Updated: 2020-12-16
Results Overview
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.

Group I
This is a single-arm non-randomized single institution phase 2 trial, designed to evaluate the therapeutic activity of CMVpp65-CTLs generated from seropositive HSCT donors when adoptively transferred into transplant recipients with persistent CMV infection or viremia. Patients eligible for this trial will be consenting recipients of related or unrelated HSCT who have an active CMV infection or persistent CMV viremia for ≥ 2 weeks despite treatment with anti-viral agents or who cannot be maintained on anti-viral therapy due to treatment related toxicity.
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.
