About this study

Official title: A Phase II Study of Venetoclax in Combination With Azacitidine in the Post-Transplant Setting for AML, T Cell Leukemia, and Mixed Phenotype Acute Leukemia

This phase II trial studies how well venetoclax and azacitidine work for the treatment of acute myeloid leukemia after stem cell transplantation. Venetoclax may stop the growth of cancer cells by blocking BCL-2, a protein needed for cancer cell survival. Chemotherapy drugs, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving venetoclax and azacitidine after a stem cell transplant may help control high risk leukemia and prevent it from coming back after the transplant.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To determine relapse-free survival after the use of venetoclax in combination with azacitidine given as maintenance therapy or for eradication of minimal residual disease in patients with high risk acute myeloid leukemia (AML) after hematopoietic stem cell transplantation (HSCT).

SECONDARY OBJECTIVES:

  1. To determine the safety and toxicity of venetoclax in combination with azacitidine (type, frequency, severity of adverse events [AEs] and relationship of AEs to venetoclax)
  2. To determine response duration, overall survival.
  3. To determine Incidence of acute and chronic graft versus host disease (GVHD)
  4. To perform matched pairs analysis to obtain bias corrected treatment comparisons of Venetoclax + Vidaza (V+V) to standard therapy in AML patients with no evidence of disease (AML D-) subgroup.

EXPLORATORY OBJECTIVE:

  1. To investigate possible relationships between baseline protein and gene expression signatures/mutation profile and BH3 profiling in predicting relapse-free survival time to the combination. This exploratory analysis will be done for the data from the entire study, accounting for the noted biological variables covariates, as well as disease status and whether or not the patient had AML, by fitting a Bayesian time-to-event regression model with RFS the outcome variable.

OUTLINE:

Patients receiving venetoclax and azacitidine for maintenance after allogeneic stem cell transplantation, receive azacitidine subcutaneously (SC) on days 1-5 and venetoclax orally (PO) once daily (QD) on days 1-7. Patients receiving venetoclax and azacitidine for minimal residual disease after allogeneic stem cell transplant, receive azacitidine SC on days 1-7 and venetoclax PO QD on days 1-14. Treatment repeats every 4-8 weeks for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

What is being measured

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

  1. Relapse-free survival (RFS) time

    Summary statistics for RFS time will be computed for all patients and within each (disease status, disease type) subgroup. RFS time distributions will be estimated within each subgroup using the method of Kaplan and Meier.

    Measured: From the date of first administration of venetoclax + azacitidine (vidaza) (V+V), assessed up to 60 days after last V+V dose

Secondary outcomes (5)

  1. Overall survival (OS) time

    Summary statistics for OS time will be computed for all patients and within each (disease status, disease type) subgroup. OS time distributions will be estimated within each subgroup using the method of Kaplan and Meier.

    Measured: Up to 60 days after last V+V dose

  2. Incidence of severe (grade 3 or 4) infection

    Will be summarized, and relevant parameters will be estimated under appropriate Bayesian models.

    Measured: Up to 60 days after last V+V dose

  3. Graft-versus-host disease

    Will be summarized, and relevant parameters will be estimated under appropriate Bayesian models.

    Measured: Up to 60 days after last V+V dose

  4. Incidence of other inter-current adverse events during follow up

    Will be summarized, and relevant parameters will be estimated under appropriate Bayesian models.

    Measured: Up to 60 days after last V+V dose

  5. Non-relapse mortality

    Defined as death from any cause, within 90 days from the start of V+V treatment that is not preceded by disease recurrence. Will be summarized, and relevant parameters will be estimated under appropriate Bayesian models.

    Measured: Within 90 days from the start of V+V treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Azacitidine and Venetoclax in people with Acute Bilineal Leukemia and Acute Biphenotypic 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?

The sponsor lists 53 inclusion and 17 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: under way, not looking for participants, as of the sponsor's last update on 5 Oct 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 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?

Relapse-free survival (RFS) time (time frame: From the date of first administration of venetoclax + azacitidine (vidaza) (V+V), assessed up to 60 days after last V+V dose). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04128501.

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 Oct 2026.
