Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Acute Myelogenous Leukemia Drug: Gemtuzumab Ozogamicin Drug: Liposome-encapsulated Daunorubicin-Cytarabine Phase 1

Detailed Description:

PRIMARY OBJECTIVES:

I. 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:

I. 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.

V. 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:

I. 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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Maximum tolerated dose (MTD) [ Time Frame: Up to day 42 ]
    MTD is defined as the cohort of participants one cohort below the cohort that develop dose-limiting toxicity (DLT) in at least 2 participants.


Secondary Outcome Measures :
  1. Objective response rate (ORR) [ Time Frame: Up to day 42 ]
    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).

  2. Proportion of participants who go on to receive allogeneic hematopoietic cell transplantation (HSCT) after achieving CR/CRi [ Time Frame: Up to 18 months ]
    The proportion of patients who receive an allogeneic HSCT following a CR/CRi response will be reported along with an exact 95% confidence interval.

  3. Duration of remission [ Time Frame: Up to 18 months ]
    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.

  4. Incidence of toxicities [ Time Frame: Up to day 42 ]
    Measured by the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

  5. Diagnosis of veno-occlusive disease (VOD) [ Time Frame: Up to 18 months ]
    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.

  6. Time to return of normal hematopoiesis [ Time Frame: From day 1 of induction, assessed up to 18 months ]
    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.

  7. Number of participants deceased at day 30 and day 60 [ Time Frame: At 30 and 60 days following the start of induction ]
    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.


Other Outcome Measures:
  1. Genotype at CD33 splicing single nucleotide polymorphism (SNP) RS12459419 [ Time Frame: Up to 18 months ]

    Will be determined by the flow cytometry mean fluorescence intensity (MFI) of the efflux of the fluorescent dye DiOC2 (Diethyloxacarbocyanine iodide) (by malignant cells. Will be assessed by dye efflux assay as described by Walter et al. 2003.

  3. Multidrug resistance activity of leukemia cell multidrug resistance protein 1 (MRD1) [ Time Frame: Up to 18 months ]
    Will be determined by the flow cytometry efflux MFI of the efflux of the fluorescent dye 5-carboxy-2?,7?-dichlorofluorescein diacetate (CDCF) by malignant cells. Will be assessed by dye efflux assay as described by Walter et al. 2003.

  4. Exome sequencing analysis [ Time Frame: Up to 18 months ]
    Tumor deoxyribonucleic acid (DNA) and participant DNA will be measured via Illumina HiSeq3000 sequencing platform to evaluate for associations between participant constitutional genotype (buccal swab sample at enrollment), leukemia genotype (bone marrow aspirate at enrollment and upon relapse), and response to therapy.

  5. Ribonucleic acid (RNA) sequencing analysis [ Time Frame: Up to 18 months ]
    Tumor RNA and participant RNA will be measured via RNA sequencing technique.
