About this study

Official title: An Exploratory Clinical Study of Multivirus-specific T Cells in the Treatment of Refractory Cytomegalovirus and/or Epstein-Barr Virus Infection After Allogeneic Hematopoietic Stem Cell Transplantation

To evaluate the safety and tolerability of partial HLA-matched VSTs against both CMV and EBV viruses in recipients of allogeneic hematopoietic stem cells with refractory viral infections (CMV and/or EBV).

Preliminary evaluation of the efficacy of partial HLA-matched VSTs against both CMV and EBV viruses in recipients of allogeneic hematopoietic stem cells with refractory viral infections (CMV and/or EBV); To monitor the duration and expansion of multi-virus VSTs cells after infusion.

Read the detailed description

This study consists of two parts: (1) The first stage is the safety evaluation of multi-virus VSTs and the exploration of DLT and MTD; (2) The second phase is to evaluate the safety and efficacy of multi-viral VSTs in selecting appropriate doses in the first phase.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Virus specific T cellsBiological

    Subjects will receive partial HLA-matched viral-specific T cells (VSTs) against both CMV and EBV on one of the following dose levels:

    Level One: 1 x 10^7 cells/m2 Level Two: 2 x 10^7cells/m2 Level Three: 5x 10^7 cellss/m2

Study groups in NCT06075927
Study groupRoleWhat they receive
VSTs infusionExperimentalPhase I (dose escalation) : An open, single-arm, dose-escalation clinical study to explore the safety, tolerability, and cytodynamic characteristics of CMV and EBV-specific T cells (VSTs), with initial efficacy observations. Subjects enrolled with refractory CMV and/or EBV infection after allogeneic hematopoietic stem cell transplantation were subjected to a 3+3 dose-climb test. Exploring the safety, dose-limiting toxicities (DLT) and maximum tolerated dose (MTD) of intravenous infusion of multi-virus VSTs. (2) Phase II (dose expansion) : According to the clinically recommended or safe and effective dose determined by the phase I climb test, the extended study of 1-2 dose groups with 20 cases per dose was performed after joint review by the investigators and project collaborators.
Receives: Biological: Virus specific T cells

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Assessment of safety and toxicity outcomes in subjects receiving VSTs infusion

    Number of participants with treatment-related adverse events as assessed by CTCAE v5.0, and graft-versus-host-disease will be summarized using descriptive statistics for each dose level

    Measured: within 56 days after the first VSTs infusion

  2. Assessment of antiviral efficacy of VSTs infusion

    Antiviral efficacy including clinical signs of viral infections, virus reinfection, and laboratory measurement of viral load after VSTs infusion will be determined

    Measured: within 56 days after the first VSTs infusion

Secondary outcomes (1)
  1. Virus-specific immune reconstitution

    Laboratory measurement of virus-specific immune reconstitution before and after VSTs infusion will be tested

    Measured: within 56 days after the first VSTs infusion

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Virus specific T cells in people with CMV Infection and EBV Infection, run by Peking University People's Hospital.

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 9 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 10 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yuanjie Ding (010-88325948, rmkyc@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assessment of safety and toxicity outcomes in subjects receiving VSTs infusion (time frame: within 56 days after the first VSTs infusion). The study lists 2 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 10 Oct 2023.
