About this study

Official title: A Phase Ib Trial With Dose Expansion Evaluating CPX-351 Plus Gemtuzumab Ozogamicin for Relapsed Acute Myelogenous Leukemia

This phase Ib trial studies the best dose of gemtuzumab ozogamicin when given together with CPX-351 in treating patients with acute myeloid leukemia that has come back after it was previously in remission. CPX-351 is a chemotherapy, which works 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. Gemtuzumab ozogamicin is a monoclonal antibody, called gemtuzumab, linked to chemotherapy called calicheamicin. Gemtuzumab attaches to CD33 (transmembrane receptor) positive cancer cells in a targeted way and delivers ozogamicin to kill them. Giving CPX-351 and gemtuzumab ozogamicin may work better in treating patients with acute myeloid leukemia, compared to giving only one of these therapies alone.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the phase II dose of the combination liposome-encapsulated daunorubicin-cytarabine (CPX-351) plus gemtuzumab ozogamicin (GO) by means of estimating maximum tolerated dose (MTD) in participants with relapsed acute myeloid leukemia (AML).

SECONDARY OBJECTIVES:

  1. To estimate the remission rate (complete remission plus complete remission with incomplete hematologic recovery) of participants in the MTD cohort who receive CPX-351 plus GO.

II. To evaluate CPX-351 plus GO as a bridge to allogeneic hematopoietic stem cell transplantation (HSCT) in participants with relapsed AML.

III. To estimate the duration of remission. IV. To evaluate for toxicity by means of Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

  1. To evaluate for the development of veno-occlusive disease at any point during the study in participants treated with CPX-351 plus GO.

VI. To evaluate time to return of normal hematopoiesis after induction therapy. VII. To evaluate 30- and 60-day survival.

EXPLORATORY OBJECTIVES:

  1. To evaluate if there is a difference in remission rate based on CD33 splicing single nucleotide polymorphism (SNP) genotype (CC, TC, or TT) in participants receiving CPX-351 plus GO.

II. To evaluate the impact that leukemia cell multidrug resistance activity have on achieving remission after treatment with CPX-351 plus GO.

III. To evaluate the possible associations of participant constitutional genotype, leukemia genotype, and response to therapy.

IV. To evaluate the possible associations of participant ribonucleic acid (RNA) expression, leukemia RNA expression, and response to therapy.

OUTLINE: This is a dose-escalation study of gemtuzumab ozogamicin when given in combination with liposome-encapsulated daunorubicin-cytarabine.

INDUCTION: Patients receive liposome-encapsulated daunorubicin-cytarabine intravenously (IV) over 90 minutes on days 1, 3, and 5, and gemtuzumab ozogamicin IV over 2 hours on day 7 in the first cohort of study participants, days 4 and 7 in the second cohort of study participants, or days 1, 4, and 7 in the third cohort of study participants, in the absence of disease progression or unacceptable toxicity. The dose expansion cohort will receive the above treatment schedule that is determined to be the maximum tolerated dose.

CONSOLIDATION: Patients who achieve complete remission (CR)/CR with incomplete hematologic recovery (CRi) receive consolidation therapy at the discretion of the treating physician and/or proceed to allogeneic HSCT.

What is being measured

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

  1. Maximum tolerated dose (MTD)

    MTD is defined as the cohort of participants one cohort below the cohort that develop dose-limiting toxicity (DLT) in at least 2 participants.

    Measured: Up to day 42

Secondary outcomes (7)
  1. Objective response rate (ORR)

    Objective response, including complete remission (CR) plus complete remission with incomplete hematologic recovery (CRi), after induction therapy will be measured using the International Working Group (IWG) Response Criteria in acute myeloid leukemia (AML).

    Measured: Up to day 42

  2. Proportion of participants who go on to receive allogeneic hematopoietic cell transplantation (HSCT) after achieving CR/CRi

    The proportion of patients who receive an allogeneic HSCT following a CR/CRi response will be reported along with an exact 95% confidence interval.

    Measured: Up to 18 months

  3. Duration of remission

    Evaluated in participants that achieve CR/CRi, and defined as number of days that elapse from first day CR/CRi to the first day that bone marrow blasts >= 5%. The median duration of remission will be reported in patients who achieved CR/CRi, along with the corresponding range.

    Measured: Up to 18 months

  4. Incidence of toxicities

    Measured by the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

    Measured: Up to day 42

  5. Diagnosis of veno-occlusive disease (VOD)

    The diagnosis of veno-occlusive disease is based on the Baltimore criteria: Bilirubin > 2.0 mg/dL, plus, painful hepatomegaly, ascites, and weight gain > 5% basal since initiating therapy with gemtuzumab ozogamicin (GO). The proportion of patients who develop VOD will be reported along with an exact 95% confidence interval.

    Measured: Up to 18 months

  6. Time to return of normal hematopoiesis

    Defined as the number of days from day 1 of induction to ANC (absolute neutrophil count) >= 1000/uL (upper limit) and platelet count >= 100,000/uL. Will be reported along with the corresponding range.

    Measured: From day 1 of induction, assessed up to 18 months

  7. Number of participants deceased at day 30 and day 60

    Mortality is defined as death having occurred in any participant that receives at least one dose of experimental therapy. Kaplan-Meier methods will estimate the overall survival at day 30 and day 60 following the start of induction. The survival estimate at these two time points will be reported along with a 95% confidence interval.

    Measured: At 30 and 60 days following the start of induction

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Gemtuzumab Ozogamicin and Liposome-encapsulated Daunorubicin-Cytarabine in people with Acute Myelogenous Leukemia, run by Jonsson Comprehensive Cancer Center at 5 sites 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 11 inclusion and 11 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: stopped early, as of the sponsor's last update on 18 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites 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?

The study was stopped early (reason given: slow accrual). Results are not available in the source record.

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?

Maximum tolerated dose (MTD) (time frame: Up to day 42). 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 NCT03904251, which also lists 1 linked publication.

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 18 Nov 2023.
