About this study
Official title: Treatment of CMV Infections With Viral-Specific T Cells Against CMV in Pediatric and Adult Immunocompromised Patients or Recipients of Allogeneic Stem Cell Transplantation
The present trial will consist of the treatment of 20 pediatric and adult Hematopoietic Stem Cell Transplantation (HSCT) recipients or immunocompromised participants diagnosed with opportunistic Cytomegalovirus (CMV) infections with virus-specific, antigen-selected T-cells. CMV-specific T-cells will be isolated from donor leukapheresis products using the CliniMACS® Prodigy. Prior studies on transfer of CMV specific T-cells have been shown to be safe and efficacious in the treatment of CMV infections.
The main trial objective is to evaluate the feasibility and safety of CMV-specific T-cell transfer in adult and pediatric participants suffering from CMV infections or reactivation following HSCT or due to other immunocompromised states (e.g.; primary immunodeficiency, cytotoxic therapy).
Participants will be followed for one year.

What is being measured
The primary outcome is the main question the study is designed to answer.
Feasibility: Number of Participants Who Drop-Out Before T-Cell Transfer
The feasibility of this intervention will in part be accomplished by measuring the number of dropped out participants before T-Cell Transfer.
Measured: up to 21 days from enrollement
Feasibility: Number of Days from Participant Enrollment to Administration of CMV-VST
The feasibility of this intervention will in part be accomplished by measuring the amount of time from participant enrollment to administration of Cytomegalovirus-Viral Specific T-Cells (CMV-VST).
Measured: up to 21 days from enrollment
Feasibility: Successful production of CMV-VST from donors
The feasibility of this intervention will be assessed by quantifying the number of successful productions of Cytomegalovirus-Viral Specific T-Cells (CMV-VST) on an intent to treat basis.
Measured: up to 21 weeks from enrollment
Safety: Number of Subjects who experience infusion-related adverse events following CMV-VST infusion
Incidence assessed by monitoring vital signs and specific adverse events
Measured: up to 4 hours after CMV-VST infusion
Safety: Number of Subjects who experience newly occurring acute GVHD grade 1
Incidence of subjects who experience newly occurring acute GVHD grade 1
Measured: up to 12 weeks from CMV-VST infusion
Safety: Number of subjects experiencing newly occurring acute GVHD grade ≥ 2 or experience aggravation of pre-existing acute GVHD
Incidence of newly occurring acute GVHD grade ≥ 2 or increase in grade of pre-existing acute GVHD
Measured: up to 12 weeks from CMV-VST infusion
Safety: Number of subjects experiencing chronic GVHD
Incidence of chronic GVHD
Measured: up to 12 weeks from CMV-VST infusion
The number of severe infusion-related adverse events or severe non-hematological adverse events
Incidence of infusion-related adverse events ≥ grade 3 and non-hematological adverse events ≥ grade 4 after CMV-VST, which are not due to pre-existing infection or original malignancy or pre-existing condition
Measured: up to 28 days from CMV-VST infusion
Safety: Time to Occurrence of GVHD
Time to occurrence of acute GVHD of any grade or to occurrence of chronic GVHD will be evaluated using the Kaplan-Meier method to assess incidence and severity of acute or chronic GVHD from day of T-cell transfer. The first day of GVHD onset at a certain grade will be used to calculate a cumulative incidence curve for that GVHD grade, acute or chronic. Overall cumulative incidence curves will be computed along with the 95% confidence intervals until Week 12 after T-cell transfer with death considered as a competing risk.
Measured: up to 12 weeks from CMV-VST infusion
Secondary outcomes (7)

Measured: up to 12 weeks from CMV-VST infusion
Efficacy: Time to ≥1 log change in viral load
Evaluation of efficacy will in part be measured by time to ≥1 log change in viral load in days.
Measured: up to 12 weeks from CMV-VST infusion

Measured: up to 12 weeks from CMV-VST infusion
Efficacy: Time to CMV Clearance
Evaluation of efficacy will in part be measured by the time to CMV clearance (defined as negative PCR) from Day 0 to first day of two subsequent negative CMV PCR studies.

Measured: up to 12 weeks from CMV-VST infusion
Efficacy: Number of CMV Reactivations Following Initial Viral Clearance
Evaluation of efficacy will in part be measured by the number of CMV reactivations following initial viral clearance until Week 52.
Measured: up to 52 weeks from CMV-VST infusion

Evaluation of efficacy will in part be measured by the overall survival. Overall survival rate (OS): time from T-cell transfer (Day 0) to death or last follow-up throughout the study from Day 1 to Week 52.
Measured: up to 52 weeks

The present trial will consist of the treatment of 20 pediatric and adult Hematopoietic Stem Cell Transplantation (HSCT) recipients or immunocompromised participants diagnosed with opportunistic Cytomegalovirus (CMV) infections with virus-specific, antigen-selected T-cells. CMV-specific T-cells will be isolated from donor leukapheresis products using the CliniMACS® Prodigy. Prior studies on transfer of CMV specific T-cells have been shown to be safe and efficacious in the treatment of CMV infections.
The main trial objective is to evaluate the feasibility and safety of CMV-specific T-cell transfer in adult and pediatric participants suffering from CMV infections or reactivation following HSCT or due to other immunocompromised states (e.g.; primary immunodeficiency, cytotoxic therapy).
Participants will be followed for one year.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing CMV-specific T-cells in people with CMV Infection and Cytomegalovirus Infections, run by University of Wisconsin, Madison at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 15 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 31 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: Slow accrual). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Feasibility: Number of Participants Who Drop-Out Before T-Cell Transfer (time frame: up to 21 days from enrollement). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Oct 2024.
