T Cell Therapy of Opportunistic Cytomegalovirus Infection

NCT02982902

Description:

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).

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.

Eligibility Criteria

        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.

        Donor eligibility

Primary Outcome Measures

Measure:Incidence of adverse events
Time Frame:Up to 100 days after transplant
Safety Issue:
Description: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

Secondary Outcome Measures

Measure:Eradication rate of opportunistic CMV infections
Time Frame:Up to 100 days after transplant
Safety Issue:
Description: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.
Measure:response rate
Time Frame:Up to 100 days after transplant
Safety Issue:
Description:A response rate of 25% is considered unacceptable; and the anticipated response rate is approximately 55% for the study population using the cell therapy.
