Combined Infusion of Cytotoxic T-Lymphocytes and Vaccination (CYNTAX)

November 21, 2016 updated by: David Gottlieb, University of Sydney

Combined Infusion of Cytotoxic T-Lymphocytes and Vaccination to Enhance Infection-Specific Immune Reconstitution Post-Allogeneic Stem Cell Transplantation

To assess the safety and biological efficacy of prophylactically administered donor-derived multi-infection specific cytotoxic T lymphocytes (CTLs) (targeting cytomegalovirus (CMV), Adenovirus (Adv), Epstein Barr virus (EBV), Varicella-Zoster virus (VZV), Influenza (Flu), BK virus (BKV), and Aspergillus (Asp)) combined with early immunisation with Influenza and VZV vaccines for the prevention of viral and fungal infection following allogeneic blood or marrow stem cell transplantation.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will analyse the safety and biological efficacy of administering the investigational products (donor-derived T cells stimulated with viral and fungal antigen expressing DC combined with Flu and VZV immunisation), for the prophylaxis of viral and fungal reactivation and/or infection following allogeneic blood or marrow transplantation. The cells will be given prophylactically a minimum of 28 days after transplantation followed by administration of the Flu and VZV vaccines 24 to 72 hours later. The AIMS are to study the safety of combining CTL infusions and vaccination as well as their effect on reconstitution of infection-specific immunity, viral and Aspergillus reactivation and infection rates after transplantation, viral load, and use of antiviral and antifungal pharmacotherapy for specific infections. The investigators will also evaluate the safety of infusions and vaccinations with respect to the development adverse events within the first 12 months post transplant.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
