T Cell Therapy of Opportunistic Cytomegalovirus Infection

September 28, 2023 updated by: Mari Dallas

Antigen Specific Adoptive T Cell Therapy for Opportunistic Cytomegalovirus Infection Occurring After Stem Cell Transplant

The purpose of this study is to determine if a specific type of cell-based immunotherapy, using T-cells from a donor that are specific against cytomegalovirus (CMV) is feasible to treat infections by CMV.

Adoptive T-cell therapy is an investigational (experimental) therapy that works by using the blood of a donor and selecting the T-cells that can respond against a specific infectious entity. These selected T-cells are then infused to the patient, to try to give the immune system the ability to fight the infection. Adoptive T-cell therapy is experimental because it is not approved by the Food and Drug Administration (FDA).

Study Overview

Detailed Description

The primary objective of this study is to determine the feasibility of the treatment of opportunistic cytomegalovirus (CMV) infections after hematopoietic stem cell transplant (HSCT) with virus-specific, antigen-selected T-cells, selected using the CliniMACS prodigy system.

Secondary Objective(s)

  • To describe the safety profile of the infusion of CMV- specific, antigen selected T-cells.
  • To describe the toxicities related to infusion of CMV- specific, antigen selected T-cells.
  • To describe the rate of eradication of opportunistic CMV infections after HSCT and and treatment with CMV-specific, antigen-selected T-cells using the CliniMACS Prodigy System.

This feasibility study will include a single treatment cohort.

Description

Inclusion Criteria:

  • Patients must have received allogeneic hematopoietic stem cell transplant and be greater than 30 days post-transplant at the time of registration
  • Patients must have documented opportunistic CMV infection, or reactivation; the criteria include (both of the following criteria must be met)

    • Patients may have asymptomatic viremia (>1000 copies/ml) OR presence of symptoms secondary to CMV infection, AND
    • Patients must have ONE OF THE NEXT FOUR CRITERIA:

      • Absence of an improvement of viral load after ≥ 14 days of antiviral therapy with ganciclovir, valganciclovir or foscarnet (decrease by at least 1 log, i.e. 10-fold) or
      • New, persistent and/or worsening CMV-related symptoms, signs and/or markers of end organ compromise while on antiviral therapy with ganciclovir, valganciclovir or foscarnet, or
      • Have contraindications or experience adverse effects of antiviral therapy with ganciclovir, valganciclovir or foscarnet.
      • Second recurrence of CMV viremia, CMV-related symptoms, signs and/or markers of end organ compromise.
  • Eastern Cooperative Oncology Group (ECOG) performance status ≤ 3
  • Women of child-bearing potential and men must agree to use adequate contraception (double barrier method of birth control or abstinence) 4 weeks prior to study entry, for the duration of study participation and for 3 months after completing treatment.
  • Subjects must have the ability to understand and the willingness to sign a written informed consent document, or assent document.

Exclusion Criteria:

  • Pregnant or breastfeeding women are excluded from this study.
  • Patients with opportunistic viral infections other than CMV.
  • Patients with active, grade 2-4, acute graft vs. host disease (GVHD), chronic GVHD or any condition requiring high doses of glucocorticosteroid (>0.5 mg/kg/day prednisone or its equivalent) as treatment
  • Treatment with antithymocyte globulin within 28 days of planned infusion of virus - specific, antigen selected T cells.
  • Treatment with virus - specific T cells within 6 weeks (42 days) of planned infusion.

Donor eligibility

  • Related donor of T cells must be at least partially HLA compatible, matching with recipient in at least 3/6 HLA loci (HLA-A, HLA-B, and HLA-DRB1 loci will be considered for this).
  • Must have evidence of a serologic response (i.e. be seropositive) against CMV.
  • Age ≥ 18 years
  • Must meet the criteria for donor selection defined in the Standard Operating Procedures of University Hospitals Seidman Cancer Center Stem Cell Transplant Program
  • Must be capable of undergoing a single standard 2 blood volume leukapheresis or donation of one unit of whole blood

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: CMV specific adoptive t-cells
This study involves a one-time infusion of the experimental CMV specific adoptive t-cells. After this infusion, patients will be followed for 4 weeks.
It is expected that the cell dose will be in the range of 10^3 - 10^5 virus - specific, antigen selected T cells per kg of recipient weight.

  • immunotherapy

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of adverse events
Time Frame: Up to 100 days after transplant
To determine the feasibility of the intervention, the study will record the incidence of adverse events, including graft versus host disease and other complications will be evaluated using binomial distribution theory and their 95% confidence intervals (CIs) will be also estimated using Wilson's method
Up to 100 days after transplant

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Eradication rate of opportunistic CMV infections
Time Frame: Up to 100 days after transplant
The eradication rate will be the disappearance of opportunistic CMV infections with the use of CMV-specific, antigen-selected T cells using the CliniMACS Prodigy System over the total number CMV infections.
Up to 100 days after transplant
response rate
Time Frame: Up to 100 days after transplant
A response rate of 25% is considered unacceptable; and the anticipated response rate is approximately 55% for the study population using the cell therapy.
Up to 100 days after transplant
