  • Patients aged ≥18 years old with relapsed/refractory AML with MAPK pathway mutations e.g. N or KRAS, PTPN11, NF1 etc. are eligible if they are not eligible for potentially curative therapy such as more effective salvage therapy or hematopoietic stem cell transplantation or who refuse these options at the time of enrollment.
  • Patient must be receiving protocol therapy as salvage 1 or 2.
  • Patients aged ≥ 18 years old, with MDS or CMML treated with hypomethylating agent (HMA) therapies who progress to AML and have no available therapies or are not candidates for available therapies, will be eligible at the time of progression to AML.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status ≤2
  • Temporary prior measures such as apheresis while eligibility work-up is being performed are allowed and not counted as a prior salvage
  • In the absence of rapidly progressing disease, the interval from prior treatment to time of initiation of protocol therapy will be at least 2 weeks or at least 5 half-lives (whichever is longer). The half-life for the therapy in question will be based on published pharmacokinetic literature (abstracts, manuscripts, investigator's brochures, or drug-administration manuals) and will be documented in the protocol eligibility document.
  • The toxicity from prior therapy should have resolved to Grade ≤1, however alopecia and sensory neuropathy Grade ≤2 not constituting a safety risk based on investigators judgement is acceptable.
  • The use of chemotherapeutic or anti-leukemic agents is not permitted during the study with the following c: (1) intrathecal (IT) therapy for patients with controlled CNS leukemia at the discretion of the PI. (2) Use of 1-2 doses of cytarabine (up to 1.5 g/m2 each dose) for patients with rapidly proliferative disease is allowed up to 7 days before the start of study therapy (7 days washout). Since the anti-leukemia effect of HMA-therapies and kinase inhibitors may be delayed, use of hydroxyurea for patients with rapidly proliferative disease is allowed on study and before the start of study therapy and will not require a washout. These medications will be recorded in the case-report form. (Rationale: Patients with kinase mutations can have very proliferative disease and the combination can induce differentiation in patients as part of response)
  • Concurrent therapy for CNS prophylaxis or continuation of therapy for controlled CNS disease is permitted. Patients with a known history of CNS disease must have been treated with CNS directed therapy, have at least 2 consecutive LPs with no evidence of CNS leukemia, and must be clinically stable for at least 4 weeks prior to enrollment and have no ongoing neurological symptoms that in the opinion of the treating physician are related to the CNS disease
  • Serum biochemical values with the following limits:
  • Patients must have adequate renal function as demonstrated by a creatinine clearance (CrCl) ≥ 50 mL/min calculated by either the Cockcroft-Gault formula, Modification of Diet in Renal Disease (MDRD) eGFR or measured by 24 hours' urine collection. For patients with BMI >23, Adjusted body weight and not Ideal Body Weight is the recommended parameter29, 30.
  • Total bilirubin <1.5 x ULN unless considered due to Gilbert's syndrome
  • Aspartate aminotransferase or alanine aminotransferase ≤2.0 x ULN (aspartate aminotransferase or alanine aminotransferase ≤3.0 x ULN if deemed related to leukemia by the treating physician)
  • White blood cell count <15 x 109/L. Hydroxyurea may be used to reduce the WBC count to ≤ 15x109/L.
  • Ability to understand and provide signed informed consent.
  • Females must be surgically or biologically sterile or postmenopausal (amenorrheic for at least 12 months) or if of childbearing potential, must have a negative serum or urine pregnancy test within 72 hours before the start of the treatment.
  • Women of childbearing potential must agree to use an adequate method of contraception during the study and until 4 months after the last treatment. Males must be surgically or biologically sterile or agree to use an adequate method of contraception during the study until 3 months after the last treatment.

About this study

To find the recommended dose of the study drugs ASTX727 and ASTX029 that can be given to patients with relapsed/refractory AML. The goal of Part 2 of the study is to learn if the dose of study drugs found in Part 1B can help to control AML.

Read the detailed description

Primary Objectives:

To determine the safety and recommended phase 2 dose (RP2D) of ASTX727 in combination with ASTX029 in patients with relapsed/refractory AML.

Secondary Objectives:

  • To assess the CR+CRi+PR and MLFS rate within 6 cycles of treatment initiation of ASTX727 in combination with ASTX029 in patients with relapsed refractory AML.
  • To determine the duration of response (DOR), event-free survival (EFS), overall survival (OS), minimal/measurable residual disease (MRD) status at response and best MRD response attained by flow-cytometry, 4- and 8-week mortality
  • To investigate correlations of response to these combinations with a pre- therapy, on-therapy, and progression 81-gene panel of gene mutations in AML.

Exploratory Objectives:

  • To investigate possible relationships between response and non-response to the combinations with myeloid mutation panel.
  • To identify leukemic subpopulations and how their signaling state in disease relates to clinical outcomes by Flow cytometry or CyTOF (mass cytometry) on patients' bone marrow samples and/or peripheral blood baseline, on treatment, remission and relapse and potentially other time-points on study.
  • To store and/or analyze surplus blood or tissue including bone marrow, if available, for potential future exploratory research into factors that may influence development of AML and/or response to the combination (where response is defined broadly to include efficacy, tolerability or safety).

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing ASTX727 and ASTX029-01 in people with Acute Myeloid Leukemia, run by M.D. Anderson Cancer Center.

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 23 inclusion and 21 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: withdrawn, as of the sponsor's last update on 12 Mar 2025. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Primary Outcome Measure (time frame: Through study completion; an average of 1 year.). 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 NCT06113289.

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 12 Mar 2025.
