About this study

Official title: A Phase I Study of Entrectinib in Combination With ASTX727 (35 mg Decitabine and 100 mg Cedazuridine) in Patients With Relapsed/Refractory TP53 Mutated Acute Myeloid Leukemia (AML)

This phase I trial tests the safety, side effects, and best dose of entrectinib when given with ASTX727 in treating patients with acute myeloid leukemia (AML) that has come back (relapsed) or that does not respond to treatment (refractory) and has a genetic change (mutation) in the TP53 gene. ASTX727 is a combination of cedazuridine and decitabine. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have a greater effect. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Entrectinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells. Giving ASTX727 and entrectinib together may kill more tumor cells in patients with AML.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To determine the maximum tolerated dose (MTD) of decitabine and cedazuridine (ASTX727) combined with entrectinib in relapsed/refractory (R/R) AML patients with TP53 mutations.

SECONDARY OBJECTIVE:

  1. To assess overall safety and preliminary anti-AML activity of combined ASTX727 and entrectinib regimen.

EXPLORATORY OBJECTIVE:

  1. To assess the potential pharmacodynamic changes observed with treatment consisting of entrectinib alone and in combination with decitabine.

OUTLINE: This is a dose-escalation study of entrectinib.

Patients receive entrectinib orally (PO) once daily (QD) on days 1-28 and ASTX727 PO QD on days 1-5. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 3 months for up to 1 year.

What is being measured

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

  1. Incidence of dose limiting toxicities (DLTs)

    Toxicities will be assessed using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE version [v] 5.0).

    Measured: From first dose of study drug (day 1 of cycle 0) to end of cycle 1 (each cycle = 28 days)

Secondary outcomes (8)
  1. Incidence of treatment-related grade >= 3 adverse events

    Treatment-related grade >= 3 adverse events will be tallied and summarized for the entire safety analysis set and within subgroups defined by each participant's assigned entrectinib dose level. AE tabulations will be constructed at both the participant-level and the event-level, with each toxicity summarized by grade (i.e., severity), duration, and system organ class. AE incidence will be reported using frequency counts and percentages with 95% exact binomial confidence intervals (CIs).

    Measured: From first dose of study drug (day 1 of cycle 0) up to 30 days post end of therapy (each cycle = 28 days)

  2. Composite complete remission (CCR) rate

    cCR is defined as the proportion of participants who attain a best response of Complete Remission with incomplete blood count recovery (CRi), Complete Remission (CR), or Complete Remission with Minimal Residual Disease (CRMRD) per 2017 European LeukemiaNet (ELN). Each response endpoint will be computed for both the safety analysis set and the efficacy analysis set, with a fraction's numerator equaling the number of participants achieving the requisite degree of response and the denominator comprising the number of participants in the respective analysis set.

    Measured: From first dose of study drug up to 2 weeks after last dose of study drug, start of new cancer therapy, or transplant, end of study follow up, death (whichever is first), assessed up to 6 months

  3. Overall response rate (ORR)

    Each response endpoint will be computed for both the safety analysis set and the efficacy analysis set, with a fraction's numerator equaling the number of participants achieving the requisite degree of response and the denominator comprising the number of participants in the respective analysis set.

    Measured: From first dose of study drug up to 2 weeks after last dose of study drug, start of new cancer therapy, or transplant (whichever is first), assessed up to 6 months

  4. Clinical benefit rate (CBR)

    Each response endpoint will be computed for both the safety analysis set and the efficacy analysis set, with a fraction's numerator equaling the number of participants achieving the requisite degree of response and the denominator comprising the number of participants in the respective analysis set.

    Measured: From first dose of study drug up to 2 weeks after last dose of study drug, start of new cancer therapy, or transplant (whichever is first), assessed up to 6 months

  5. Proportion transplanted

    The proportion of participants in the safety analysis set who transition to stem cell transplantation will be computed and reported as a percentage with a 95% exact CI.

    Measured: From first dose of study drug up to end of follow-up or death, assessed up to 6 months

  6. Duration of response (DOR)

    Will be estimated by the Kaplan-Meier method and reported with the median and rates at various landmark times (e.g., 3 months, 6 months, 1 year), each accompanied with a 95% complementary log-log CI.

    Measured: From first dose of study drug up to end of follow-up, loss of partial response (PR), progression or death (whichever is first), assessed up to 6 months

  7. Event free survival (EFS)

    Will be estimated by the Kaplan-Meier method and reported with the median and rates at various landmark times (e.g., 3 months, 6 months, 1 year), each accompanied with a 95% complementary log-log CI.

    Measured: From first dose of study drug up to end of follow-up, relapse, progression, start of new cancer therapy, study drug discontinuation due to toxicity or death (whichever is first), assessed up to 6 months

  8. Overall survival (OS)

    Will be estimated by the Kaplan-Meier method and reported with the median and rates at various landmark times (e.g., 3 months, 6 months, 1 year), each accompanied with a 95% complementary log-log CI.

    Measured: From first dose of study drug up to end of follow-up or death, assessed up to 6 months

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 13 inclusion and 14 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 15 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 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.
