About this study

Official title: A Phase 1, First in Human Study of Adoptive T Cell Therapy With T Cells Stimulated by Dendritic Cell (DC)/Tumor Fusions in Combination With Decitabine and Venetoclax in Patients With Acute Myeloid Leukemia (AML)

The goal of this research study is to test if the combination of a new T cell therapy (dendritic cell (DC) / acute myeloid leukemia (AML) primed T cells), vaccine (DC/AML fusion vaccine) and standard of care decitabine and venetoclax is feasible and safe and effective for treatment of acute myeloid leukemia (AML).

The names of the study drugs involved in this study are:

  • DC/AML fusion vaccine (immune cell vaccine)
  • Granulocyte-macrophage colony-stimulating factor (GM-CSF) (a type of growth factor or hormone)
  • DC/AML Primed T cells (immune cells)
  • Decitabine (a type of chemotherapy drug)
  • Venetoclax (a type of antineoplastic agent)
Read the detailed description

The study is a dose escalation phase I clinical trial to evaluate the feasibility, safety, clinical and immune effects of adoptive T cell therapy with DC/AML Primed T cells in participants with acute myeloid leukemia (AML) treated with decitabine and venetoclax.

The U.S. Food and Drug Administration (FDA) has not approved DC/AML Vaxprimed T cells as a treatment for any disease. This is the first time that DC/AML Primed T cells will be given to humans.

The U.S. Food and Drug Administration (FDA) has not approved DC/AML fusion vaccine as a treatment for any disease. The U.S. Food and Drug Administration (FDA) has approved GM-CSF, decitabine and venetoclax as treatment options for acute myeloid leukemia (AML).

It is expected that about 30 people will take part in this research study

Dose-EscalationExperimentalA standard 3+3 dose escalation design will be used to find the maximum tolerated dose (MTD) of T cells. If less than 1 out of 3 or less than 2 out of 6 participants experience a dose-limiting toxicity (DLT) in a given cohort then escalation will proceed to the next dosing level. If 2 out of 6 participants experience a DLT then the prior dose level will be defined as the MTD. An additional 12 participants will be treated at the MTD. -Cycles 5 - 7 (42-day cycles): * Days 1 - 5: predetermined dose of Decitabine 1x daily * Day 15: predetermined dose of DC/AML Primed T cells 1x daily * Days 1 - 14: predetermined dose of Venetoclax 1x daily * Day 29: predetermined dose of DC/AML fusion vaccine 1x daily * Day 29: predetermined dose of GM-CSF 1x daily Follow up visits monthly for 6 months Longer term follow up every 3 months for 2 years then yearly for 3 years

What is being measured

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

  1. Successful Manufacture and Administration Rate of Vaccine-Educated T Cells

    Successful manufacture and administration rate is defined as the proportion of enrolled participants for whom autologous vaccine-educated T cells are successfully manufactured and administered per protocol.

    Measured: 28 weeks

  2. Maximum Tolerated Dose (MTD) of Vaccine-Educated T Cells

    The MTD is defined as the highest dose level that one or fewer participants experiences a dose-limiting toxicity (DLT) or one dose level below the maximum administered dose level where two or more participants experience a DLT.

    Measured: 56 Days

  3. Toxicity Rate of Vaccine-Educated T Cells, Including CRS, Neurotoxicity, and Infections

    Toxicity rate of vaccine-educated T cells is defined as the proportion of participants who experience at least one toxicity, including cytokine release syndrome, neurotoxicity, or infections, out of all participants who receive at least one T-cell infusion.

    Measured: 5 years

Secondary outcomes (4)
  1. Relapse-Free Survival (RFS) at 1 Year Post Administration of Vaccine Educated T Cells

    RFS based on Kaplan-Meier method is defined as the time from the first T-cell infusion to the first documented disease relapse or death from any cause. Participants without relapse will be censored at the last disease assessment. Relapse is defined as the reappearance of blasts in the blood, or a bone marrow aspirate and biopsy showing >5% blasts, not attributable to another cause. If there are no circulating blasts, a repeat bone marrow performed >1 week later documenting more than 5% blasts is necessary to meet criteria for relapse.

    Measured: 1 year

  2. Relapse-Free Survival (RFS) at 2 Years Post Administration of Vaccine Educated T Cells

    RFS based on Kaplan-Meier method is defined as the time from the first T-cell infusion to the first documented disease relapse or death from any cause. Participants without relapse will be censored at the last disease assessment. Relapse is defined as the reappearance of blasts in the blood, or a bone marrow aspirate and biopsy showing >5% blasts, not attributable to another cause. If there are no circulating blasts, a repeat bone marrow performed >1 week later documenting more than 5% blasts is necessary to meet criteria for relapse.

    Measured: 2 years

  3. MRD Negative Conversion Rate

    MRD negative conversion rate is defined as the proportion of participants who convert from MRD-positive status at baseline to MRD-negative status at a subsequent post-baseline assessment,

    Measured: MRD samples are collected up to 6 months after the last cell therapy dose.

  4. Median Overall Survival (OS)

    Overall survival (OS), estimated using the Kaplan-Meier method, is defined as the time from registration to death from any cause. Participants without a death event will be censored at the last date they are known to be alive.

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing DC/AML Fusion Vaccine, T-Cell Therapy and Decitabine in people with Acute Myeloid Leukemia and Acute Myeloid Leukemia, in Relapse, run by David Avigan 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 17 inclusion and 24 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: looking for participants now, as of the sponsor's last update on 5 May 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 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?

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?

Contact David Avigan, MD (617-667-9920, davigan@bidmc.harvard.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Successful Manufacture and Administration Rate of Vaccine-Educated T Cells (time frame: 28 weeks). The study lists 3 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 5 May 2026.
