  • White blood cell (WBC) count < 25,000 cells/μL before administration of VenBom on Cycle 1 Day 1. Note: During Cycle 1 only, hydroxyurea may be used to control the level of circulating leukemic blast cell counts to not lower than 10,000 cells/μL.
  • Platelet count ≥ 20,000 cells/μL before administration of VenBom on Cycle 1 Day 1. Note: Transfusions permitted to achieve this threshold.
  • Suitable venous access to allow for all study related-blood sampling (safety and research).
  • Estimated life expectancy, in the judgment of the Investigator, that will permit receipt of at least 3 months of treatment.
  • Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care or other benefits to which they are entitled to receive.
  • Female patients who:
  • Are postmenopausal (No menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However, in the absence of 12 months of menorrhoea, a single FSH measurement is insufficient.), OR
  • Are surgically sterile, OR
  • If they are of childbearing potential: Agree to practice 1 highly effective method and 1 additional effective (barrier) method of contraception, at the same time, from the time of signing the informed consent through 4 months after the last dose of study drug (female and male condoms should not be used together), OR Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the patient. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception).

  • Agree to practice effective barrier contraception during the entire study treatment period and through 4 months after the last dose of study drug (female and male condoms should not be used together), OR
  • Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the patient. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods for the female partner] withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception).

Study groupRoleWhat they receive
Part 1: VenBom Dose Escalation/De-Escalation CohortExperimentalParticipants in this group will receive Venetoclax and Bomedemstat (VenBom) in a dose escalation/de-escalation design to determine the maximum tolerated dose (MTD). Participants will receive VenBom for 21 days on (Days 1-21) and seven days off (Days 22-28) during a 28-day cycle for three months. Doses will be administered as follows: * Dose Level -2: 0.375 mg/kg daily (d) Bomedemstat and 200 mg/d Venetoclax; * Dose Level -1: 0.75 mg/kg/d Bomedemstat and 200 mg/d Venetoclax; * Dose Level 1 (Starting): 1.5 mg/kg/d Bomedemstat and 200 mg/d Venetoclax; * Dose Level 2: 3 mg/kg/d Bomedemstat and 200 mg/d Venetoclax; * Dose Level 3: 3 mg/kg/d Bomedemstat and 400 mg/d Venetoclax. Participants will receive three cycles of VenBom, but may continue to receive treatment as long as receiving clinical benefit or until disease progression. Participants starting at dose levels -2, -1, or 1 receive 100 mg Venetoclax on Cycle 1 Day 1.
Receives: Drug: Bomedemstat; Drug: Venetoclax
Part 2: VenBom Expansion CohortExperimentalParticipants in this group will receive VenBom therapy at the most appropriate dose determined in Part 1. Participants will continue to receive treatment as long as receiving clinical benefit or until disease progression.
Receives: Drug: Bomedemstat; Drug: Venetoclax

What is being measured

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

  1. Incidence of Treatment-Emergent Toxicity

    Toxicity is defined as including dose limiting toxicities (DLTs), serious adverse events (SAEs) and adverse events (AEs) in study participants. Toxicity will be assessed using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, per physician discretion.

    Measured: Up to 72 weeks

  2. Recommended Phase 2 Dose (RP2D)

    The RP2D of combination VenBom therapy will be determined as the maximum tolerated dose of study treatment as assessed by treating physician using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.

    Measured: Up to 72 weeks

Secondary outcomes (2)
  1. Overall Response Rate (ORR)

    Rate of participants achieving complete response (CR), CR with incomplete neutrophil or platelet recovery (CRi), CR with incomplete hematologic recovery (CRh), partial remission (PR), or morphologic leukemia free state (MLFS) response to study treatment. Response will be assessed by treating physician using the modified 2017 European LeukemiaNet (ELN) AML Response Criteria.

    Measured: Up to 72 weeks

  2. Proportion of Participants with Measurable Residual Disease

    Proportion of patients with measurable residual disease (MRD) evaluated by multiparameter flow cytometry (MFC) at each bone marrow aspirate collection.

    Measured: Up to 72 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Bomedemstat and Venetoclax in people with Acute Myeloid Leukemia and Refractory Acute Myeloid Leukemia, run by Terrence J Bradley, MD 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 22 inclusion and 29 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 8 Jan 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 Alessia Zoso, PhD (305-243-2373, azoso@med.miami.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Treatment-Emergent Toxicity (time frame: Up to 72 weeks). 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 8 Jan 2026.
