  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Diagnosis of untreated "high-grade" myeloid neoplasm (>=10% blasts in blood or bone marrow) or AML other than acute promyelocytic leukemia (APL) with t(15;17)(q22;q12) or variants according to the 2016 World Health Organization (WHO) classification.

About this study

Official title: Randomized Phase 2 Trial of CPX-351 (Vyxeos) vs. CLAG-M (Cladribine, Cytarabine, G-CSF, and Mitoxantrone) in Medically Less-Fit Adults With Acute Myeloid Leukemia (AML) or Other High-Grade Myeloid Neoplasm

This phase II trial studies how well CPX-351 or the CLAG-M regimen (consisting of the drugs cladribine, cytarabine, G-CSF, and mitoxantrone) works in treating medically less-fit patients with acute myeloid leukemia or other high-grade myeloid neoplasms. Drugs used in chemotherapy, such as CPX-351, cladribine, cytarabine, G-CSF, and mitoxantrone, 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 CPX-351 or the CLAG-M regimen at doses typically used for medically-fit patients with acute myeloid leukemia may work better than reduced doses of CPX-351 in treating medically less-fit patients with acute myeloid leukemia or other high-grade myeloid neoplasms.

Read the detailed description

OUTLINE: Patients are randomized to 1 of 2 arms in a 1:1 fashion. ARM I = CPX-351; ARM II = CLAG-M.

ARM I (INDUCTION): Patients receive CPX-351 intravenously (IV) over 90 minutes on days 1, 3, and 5 in the absence of disease progression or unacceptable toxicity. Patients who achieve a response other than an MRDneg CR receive a second course of CPX-351 intravenously IV over 90 minutes on days 1, 3, and 5 in the absence of disease progression or unacceptable toxicity.

ARM I (POST-REMISSION): Patients who achieve a CR or CR with incomplete hematologic recovery (CRi) receive a reduced dose of CPX-351 IV over 90 minutes on days 1, 3, and 5 for up to 4 additional courses in the absence of disease progression or unacceptable toxicity.

ARM II (INDUCTION): Patients receive cladribine IV over 2 hours on days 1-5, cytarabine IV over 2 hours on days 1-5, G-CSF subcutaneously (SC) on days 0-5, and mitoxantrone IV over 60 minutes on days 1-3 in the absence of disease progression or unacceptable toxicity. Patients who achieve a response other than an MRDneg CR receive a second course of cladribine IV over 2 hours on days 1-5, cytarabine IV over 2 hours on days 1-5, G-CSF SC on days 0-5, and mitoxantrone IV over 60 minutes on days 1-3 in the absence of disease progression or unacceptable toxicity.

ARM II (POST-REMISSION): Patients who achieve a CR/CRi receive an intermediate dose of cytarabine IV over 2 hours on days 1-6 for up to 4 additional courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically for up to 5 years.

What is being measured

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

  1. 3-month Overall Survival (OS)

    Will evaluate whether CPX-351 or cladribine, cytarabine, granulocyte colony-stimulating factor (G-CSF), and mitoxantrone (CLAG-M), at doses typically used for medically-fit adults with AML, improve 3-month overall survival in medically-unfit adults with AML compared to attenuated dose CPX-351 as used in our previous institutional trial (32 units/m2 per dose).

    Measured: Up to 3 months from date of start of protocol therapy

Secondary outcomes (10)
  1. Complete Remission (CR) Rates

    Will compare CR rates between the study arms.

    Measured: Up to 5 years post treatment

  2. MRDneg CR Rates

    Will compare MRDneg CR rates between the study arms.

    Measured: Up to 5 years post treatment

  3. Response Duration

    Will compare response duration between the study arms.

    Measured: Up to 5 years post treatment

  4. Relapse-free Survival

    Will compare RFS between the study arms.

    Measured: Up to 5 years post treatment

  5. Incidence of Adverse Events

    Will use the CTCAE (National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events) version 5.0 for toxicity and adverse event reporting. Will describe the toxicity profile and infectious complications of each study treatment.

    Measured: AEs were recorded from the time of first exposure to the therapy (start of the first drug administration infusion on day 1) until 4 weeks after the last dose. All-Cause Mortality was monitored from study start to data cut-off dates 5/27/2020 to 9/18/2025

  6. 30-day Mortality Rate

    30-day mortality rate from start of treatment

    Measured: At 30 days

  7. 60-day Mortality

    60-day mortality rate from start of treatment

    Measured: At 60 days

  8. Quality of Life (QOL): Questionnaire

    QOL of patients will be assessed longitudinally using the European Organization for Research and Treatment of Cancer (EORTC) core QOL questionnaire (QLQ-C30) and the newly developed acute myeloid leukemia-specific QOL instrument.

    QOL measures for Global Health Status (GHS), Functional Score, and Symptom Score were scored on a 0-100 scale with lower scores indicating worse outcomes.

    Measured: Up to 5 years post treatment

  9. Patient Use of Medical Resources (e.g. Transfusions)

    Electronic medical chart review to enumerate the number of platelet and red blood cell transfusions administered.

    Measured: Up to 5 years post treatment

  10. Patient Use of Medical Resources (e.g. Transfusions)

    Electronic medical chart review to enumerate the number of days spent on IV antimicrobial therapy and the number of days spent in the ICU.

    Measured: Up to 5 years post treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Liposome-encapsulated Daunorubicin-Cytarabine, Cladribine and Cytarabine in people with Acute Myeloid Leukemia and Myeloid Neoplasm, run by Fred Hutchinson 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 8 inclusion and 6 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: finished, as of the sponsor's last update on 29 Jun 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?

Yes. Results are posted in the registry (first posted 14 May 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

3-month Overall Survival (OS) (time frame: Up to 3 months from date of start of protocol therapy). 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 29 Jun 2026.
