About this study

Official title: Anti-Viral Central Memory CD8 Veto Cells in Haploidentical Hematopoietic Stem Cell Transplantation

This phase I/II trial studies how well cytokine-treated veto cells work in treating patients with hematologic malignancies following stem cell transplant. Giving chemotherapy and total-body irradiation before a stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient, they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Cytokine-treated veto cells may help the transplanted donor cells to develop and grow in recipients without causing graft-versus-host-disease (GVHD - when transplanted donor tissue attacks the tissues of the recipient's body).

Read the detailed description

PRIMARY OBJECTIVE:

  1. To determine the optimal dose of anti-viral veto cells, defined as the dose which achieves engraftment without severe graft-vs-host disease (GVHD) at 42 days after non-myeloablative megadose T cell depleted haploidentical hematopoietic cell transplantation (HCT).

SECONDARY OBJECTIVES:

  1. Toxicity. II. Response rate. III. Time to progression. IV. Infections. V. Immune reconstitution. VI. Overall survival up to 1 year.

OUTLINE: This is a dose-escalation study of cytokine-treated veto cells.

CONDITIONING REGIMEN: Patients receive anti-thymocyte globulin (ATG) intravenously (IV) over 4 hours on days -9 to -7 and fludarabine IV over 1 hour on days -6 to -3, then undergo total body irradiation (TBI) on day -1.

TRANSPLANT: Patients undergo peripheral blood stem cell transplantation (PBSCT) IV over 30-60 minutes on day 0.

GVHD PROPHYLAXIS: Patients receive cyclophosphamide IV over 3 hours on days +3 and +4 and cytokine-treated veto cells IV over 30-60 minutes on day +7.

After completion of stem cell transplant, patients are followed up once a week for 4 weeks, once a month for 3 months, and then periodically for one year.

What is being measured

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

  1. Optimal dose of donor-derived cytokine-treated veto cells

    For the purpose of dose-finding, toxicity is defined as steroid resistant grade 3 or 4 graft-versus-host-disease (GVHD), or death from any cause, within 42 days of veto cell infusion.

    Measured: Within 42 days of cytokine-treated veto cell infusion

  2. Efficacy of veto cells

    Efficacy is defined as the patient being alive and engrafted at day 42 post veto cell infusion.

    Measured: At day 42 post cytokine-treated veto cell infusion

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Anti-Thymocyte Globulin, Cyclophosphamide and Cytokine-treated Veto Cells in people with Acute Lymphoblastic Leukemia and Acute Myeloid Leukemia, run by M.D. Anderson Cancer Center 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?

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: under way, not looking for participants, as of the sponsor's last update on 11 Jun 2026. 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 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?

This study is still under way. Results are not available in the source record yet.

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?

Optimal dose of donor-derived cytokine-treated veto cells (time frame: Within 42 days of cytokine-treated veto cell 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 11 Jun 2026.
