Study Details

Study Description

Brief Summary

This phase I/II trial studies the side effects and best dosing frequency of gemtuzumab ozogamicin when given in combination with granulocyte colony stimulating factor (G-CSF), cladribine, cytarabine and mitoxantrone (GCLAM) and to see how well they work in treating participants with acute myeloid leukemia or high-grade myeloid tumors (neoplasms) that have not been previously treated. Antibody-drug conjugates, such as gemtuzumab ozogamicin, act by directly delivering toxic chemotherapy to cancer cells. Granulocyte colony stimulating factor is a growth factor used to stimulate leukemia cells and render them more sensitive to chemotherapy drugs. Drugs used in chemotherapy, such as cladribine, cytarabine and mitoxantrone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving gemtuzumab ozogamicin in combination with G-CSF, cladribine, cytarabine and mitoxantrone hydrochloride may work better in treating participants with acute myeloid leukemia or high-grade myeloid neoplasm.

Phase 1/Phase 2

Detailed Description

PRIMARY OBJECTIVES:
  1. To determine the maximum-tolerated dose (MTD) of gemtuzumab ozogamicin (GO) when added to GCLAM in patients with newly-diagnosed AML requiring induction chemotherapy. (Phase I) II. To evaluate the 6-month and 1-year event-free survival (EFS) rate with GO + GCLAM treated at the MTD. (Phase II)
SECONDARY OBJECTIVES:
  1. Describe, within the limits of a phase 1/2 study, the toxicity profile of the study regimen.

  2. Compare, within the limits of a phase 1/2 study, measurable residual disease (MRD) rates with GO + GCLAM at the MTD to patients treated previously with GCLAM alone.

  3. Estimate, within the limits of a phase 1/2 study, the relationship between MRD status after induction therapy and relapse risk/time to relapse as well as relapse-free and overall survival.

  4. Compare, within the limits of a phase 1/2 study, complete remission rates with GO + GCLAM at the MTD to patients treated previously with GCLAM alone.

  5. Compare, within the limits of a phase 1/2 study, overall survival rates with GO + GCLAM at the MTD to patients treated previously with GCLAM alone VI. Evaluate, within the limits of a phase 1/2 study, the impact of GO dosing regimens on the duration of cytopenias.

  6. Collect biological specimens for use for the future laboratory investigation of biomarkers for response to GO.

OUTLINE: This is a phase I dose escalation study of gemtuzumab ozogamicin followed by a phase II study.

INDUCTION THERAPY: Participants receive gemtuzumab ozogamicin intravenously (IV) either as a single dose on day 1, or as three doses on days 1, 4, and 7. Participants also receive G-CSF subcutaneously (SC) on days 0-5, cladribine IV over 2 hours on days 1-5, cytarabine IV over 2 hours on days 1-5, and mitoxantrone hydrochloride IV on days 1-3. Patients who do not achieve a CR or CRi following the first cycle of induction are eligible for a second cycle, which is given without gemtuzumab ozogamicin. Participants with a complete remission (CR) or complete remission with incomplete count recovery (CRi) may then proceed to Post-Remission Therapy.

POST-REMISSION THERAPY: Participants receive G-CSF, cladribine, and cytarabine as in Induction Therapy during cycle 1, and cytarabine IV every 12 hours on days 1-6 of cycles 2-3. Treatment repeats every month for up to 3 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, participants are followed up every 3 months for 5 years.

  • Outcome Measures

    Primary Outcome Measures

    1. Maximum tolerated dose (MTD) of gemtuzumab ozogamicin (GO) when added to GCLAM (Phase 1) [At time of count recovery, second cycle of treatment, response assessment or removal from protocol (at approximately 1 month).]

      Defined as the highest dose studied in which the incidence of Dose Limiting Toxicity (DLT) is ≤33% (≤4 of 12 patients experiencing DLT), defined as any Grade 3 non-hematologic toxicity lasting >48 hours that results in >7-day delay of the subsequent treatment cycle, with the exception of febrile neutropenia or infection or toxicities secondary to febrile neutropenia or infection, or any Grade ≥4 non-hematologic toxicity except febrile neutropenia/infection (or toxicities secondary to febrile neutropenia or infection) unless felt to be a direct consequence of treatment-related toxicity (e.g. intestinal infection following mucosal barrier breakdown), and with the exception of constitutional symptoms if recovery to Grade ≤2 within 14 days. The National Cancer Institute Common Terminology Criteria for Adverse Events v5.0 will be used.

    2. Event-free survival (EFS) rate (Phase 2) [From the start of study treatment, assessed at 6 months and 1 year]

      A two-stage design will be used to evaluate the EFS. Patients treated at the maximum tolerated dose (MTD) from the phase 1 portion of the trial will be used in the phase 2 analysis. If censoring occurs, secondary analyses analyzing 6-month or 1-year EFS accounting for censoring will be done, including estimating 6-month or 1-year EFS using the Kaplan-Meier method. The first stage of the two-stage phase 2 design will evaluate 30 patients. If 20 or more of the first 30 patients are alive without event at 6-months after study registration, an additional 30 patients will be enrolled. If 46 or more of the 60 patients treated at the MTD are alive and without event at 6-months after study registration, the study will consider the regimen of interest for further investigation.

    Secondary Outcome Measures

    1. Remission rates [Up to 5 years]

      Will be estimated and 95% confidence intervals will be calculated. Regression models (logistic regression for binary endpoints, Cox regression for time-to-event endpoints [Cox models for the hazard of the subdistribution for events with competing risks]) will be used to compare outcomes with patients who have received GCLAM without GO at our institution, controlling for measured prognostic factors.

    2. Measurable residual disease (MRD) rates [Up to 5 years]

      Will be estimated and 95% confidence intervals will be calculated. Regression models (logistic regression for binary endpoints, Cox regression for time-to-event endpoints [Cox models for the hazard of the subdistribution for events with competing risks]) will be used to compare outcomes with patients who have received GCLAM without GO at our institution, controlling for measured prognostic factors.

    3. Incidence of adverse events reported using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 [Up to 5 years]

      Will be estimated and 95% confidence intervals will be calculated. Regression models (logistic regression for binary endpoints, Cox regression for time-to-event endpoints [Cox models for the hazard of the subdistribution for events with competing risks]) will be used to compare outcomes with patients who have received GCLAM without GO at our institution, controlling for measured prognostic factors.

    4. EFS [Up to 5 years]

      Will be estimated using the Kaplan-Meier method. Regression models (logistic regression for binary endpoints, Cox regression for time-to-event endpoints [Cox models for the hazard of the subdistribution for events with competing risks]) will be used to compare outcomes with patients who have received GCLAM without GO at our institution, controlling for measured prognostic factors.

    5. Relapse-free survival [Up to 5 years]

      Will be estimated using the Kaplan-Meier method. Time to relapse will be estimated using non-parametric estimates of the cumulative incidence curve with death analyzed as a competing event. Regression models (logistic regression for binary endpoints, Cox regression for time-to-event endpoints [Cox models for the hazard of the subdistribution for events with competing risks]) will be used to compare outcomes with patients who have received GCLAM without GO at our institution, controlling for measured prognostic factors.

    6. Overall survival [Up to 5 years]

      Will be estimated using the Kaplan-Meier method. Regression models (logistic regression for binary endpoints, Cox regression for time-to-event endpoints [Cox models for the hazard of the subdistribution for events with competing risks]) will be used to compare outcomes with patients who have received GCLAM without GO at our institution, controlling for measured prognostic factors.
