Testing the Combination of Inotuzumab Ozogamicin and Lower Dose Chemotherapy Compared to Usual Chemotherapy for Adults With B-Cell Acute Lymphoblastic Leukemia or B-Cell Lymphoblastic Lymphoma

April 26, 2024 updated by: Alliance for Clinical Trials in Oncology

A Randomized Phase II Study Comparing Inotuzumab Plus Chemotherapy Versus Standard Chemotherapy in Older Adults With Philadelphia-Chromosome-Negative B-Cell Acute Lymphoblastic Leukemia

This phase II trial compares the combination of inotuzumab ozogamicin and chemotherapy to the usual chemotherapy in treating patients with B-cell acute lymphoblastic leukemia or B-cell lymphoblastic lymphoma. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a drug, called CalichDMH. Inotuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD22 receptors, and delivers CalichDMH to kill them. Chemotherapy drugs 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 inotuzumab ozogamicin with chemotherapy may help shrink the cancer and stop it from returning.

Study Overview

Detailed Description

PRIMARY OBJECTIVE:

I. To compare undetectable measurable residual disease (MRD) event-free survival (EFS) rate of the experimental arm (A) to standard arm (B) with EFS defined as time from randomization to occurrence of an event.

SECONDARY OBJECTIVES:

I. To determine overall response rate (complete response [CR], CR + complete remission with incomplete platelet counts [CRp], CR + complete remission with partial hematologic recovery [CRh], CR + complete remission with incomplete blood count recovery [CRi]) at designated time points (after cycle 1, after cycle 2, end of intensive phase) in each treatment arm.

II. To determine rate of flow cytometry MRD-negativity (undetectable or detectable < 10^-4) at designated time points (after cycle 1, after cycle 2, end of intensive phase) in each treatment arm.

III. To compare MRD response by central aspirate multiparameter flow cytometry (Wood lab) to next generation sequencing MRD assessment (clonoSEQ, Adaptive) of blood and bone marrow at designated time points (after cycle 1, after cycle 2, and end of intensive phase) and to determine association with outcome, in each treatment arm.

IV. To determine the event-free survival (EFS) standard-definition (event defined as failure to achieve morphologic remission by cycle 2, hematologic relapse, death), disease-free survival (DFS), overall survival (OS) of each arm (median, 6-month, 1-year, 2-year, 3-year) in each treatment arm.

V. To determine proportion of patients who proceed to allogeneic transplant after initial response (without intervening salvage therapy) in each treatment arm.

VI. To determine rate of liver toxicity (grade 3-5 alanine aminotransferase [ALT] increase, aspartate aminotransferase [AST] increase, bilirubin increase, alkaline phosphatase increase).

VII. To describe the safety and tolerability of each arm including rate of grade 3-5 non-hematologic toxicity and treatment-related mortality (grade 5 toxicity VIII. To determine rate of delays in intensive-phase chemotherapy due to neutropenia and thrombocytopenia (in responding patients).

IX. To assess the baseline variations in comorbidity burden, physical, nutritional, and cognitive function of the study participants, and explore the association between comorbidity burden, physical, nutritional, and cognitive function, and the outcomes of therapy (grade 3-5 non-hematological toxicities, and OS).

X. To explore the longitudinal changes in physical, nutritional, and cognitive function among the experimental and control groups.

XI. To compare the burden of patient-reported symptomatic adverse events between treatment arms using the Patient Reported Outcomes - Common Terminology Criteria for Adverse Events (PRO-CTCAE).

XII. To correlate specific karyotype groups (normal or various primary and secondary chromosomal abnormalities) with clinical and laboratory parameters.

XIII. To correlate specific karyotype groups with response rates, response duration, MRD, and survival in patients treated on this study.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A:

INDUCTION: Patients receive cyclophosphamide intravenously (IV) over 3 hours every 12 hours (Q12H) on days 1-3 of cycles 1, 3, 5, and 7, vincristine IV on days 1 and 8 of cycle 1, 3, 5, and 7, dexamethasone IV or orally (PO) on days 1-4 and 11-14 of cycles 1, 3, 5, and 7, inotuzumab ozogamicin IV over 1 hour on days 2 and 8 of cycles 1-4, methotrexate IV over 24 hours on day 1 of cycles 2, 4, 6, and 8, cytarabine IV over 3 hours Q12H on days 2-3 of cycles 2, 4, 6, and 8, and methylprednisolone IV over 2 hours Q12H on days 1-3. Patients with leukemic blasts expressing CD20 also receive rituximab IV on days 2 and 8 of cycles 1-4. For patients >= 70 years of age, treatment repeats every 28 days for 2 cycles (an additional 2 cycles may be given at the discretion of the principal investigator [PI]) in the absence of disease progression or unacceptable toxicity. For patients < 70 years of age, treatment repeats every 28 days for 8 cycles in the absence of disease progression or unacceptable toxicity.

MAINTENANCE: Patients receive vincristine IV on day 1, prednisone PO daily on days 1-5, mercaptopurine PO twice daily (BID) on days 1-28, and methotrexate PO weekly. Treatment repeats every 28 days for up to 24 cycles or 2 years, whichever comes first, in the absence of disease progression or unacceptable toxicity.

ARM B:

INDUCTION: Patients receive cyclophosphamide IV over 3 hours Q12H on days 1-3 of cycle 1, 3, 5, and 7, vincristine IV on days 1 and 8 of cycles 1, 3, 5, and 7, dexamethasone IV or PO on days 1-4 and 11-14 of cycle 1, 3, 5, and 7, doxorubicin IV over 24 hours on day 4 of cycles 1, 3, 5, and 7, methotrexate IV over 24 hours on day 1 of cycles 2, 4, 6, and 8, cytarabine IV over 3 hours Q12H on days 2-3 of cycles 2, 4, 6, and 8, and methylprednisolone IV over 2 hours Q12H on days 1-3 of cycles 2, 4, 6, and 8. Patients with leukemic blasts expressing CD20 also receive rituximab IV on days 2 and 8 of cycles 1-4. For patients >= 70 years of age, treatment repeats every 28 days for 2 cycles (an additional 2 cycles may be given at the discretion of the PI) in absence of disease progression or unacceptable toxicity. For patients < 70 years of age, treatment repeats every 28 days for 8 cycles in the absence of disease progression or unacceptable toxicity.

MAINTENANCE: Patients receive vincristine IV on day 1, prednisone PO daily on days 1-5, mercaptopurine PO BID on days 1-28, and methotrexate PO weekly. Treatment repeats every 28 days for up to 24 cycles or 2 years, whichever comes first, in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 2 months until 1 year after completion of therapy, every 3 months until 2 years after completion of therapy, and then every 6 months until 5 years from study registration.

Description

Inclusion Criteria:

  • PRE-REGISTRATION ELIGIBILITY CRITERIA (STEP 0)
  • Research bone marrow or peripheral blood submission

    * This bone marrow or peripheral blood submission is mandatory prior to registration/randomization as baseline for real-time MRD analysis. The bone marrow sample should be from the first aspiration (i.e., first pull). Aspirate needle should be redirected if needed to get first pull bone marrow aspirate. It should be obtained as soon after pre-registration as possible

  • REGISTRATION INCLUSION CRITERIA (STEP 1)
  • Diagnosis of B-cell acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LBL) per World Health Organization (WHO) 2016 criteria. Patients must have >= 5% blasts in the bone marrow or blood. Patients with lymphoblastic lymphoma (LBL) without measurable marrow involvement (>= 5% blasts) are not eligible

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Arm A (inotuzumab ozogamicin, chemotherapy)

Induction: For cycles 1-4 on days 2 and 8, patients receive inotuzumab ozogamicin IV and IT chemotherapy consisting of alternating Cytarabine and Methotrexate. Patients with leukemic blasts expressing CD20 also receive rituximab IV on days 2 and 8 of cycles 1-4. For cycles 1,3,5,7, patients receive cyclophosphamide intravenously (IV) on days 1-3, mesna IV, vincristine IV on days 1 and 8, and dexamethasone IV or orally (PO) on days 1-4 and 11-14. For cycles 2,4,6,8, patients receive methotrexate on day 1, cytarabine IV on days 2-3, and methylprednisolone on days 1-3. Patients >= 70 years of age receive either 2 or 4 cycles of treatment. Patients < 70 years of age receive up to 8 cycles of treatment.

Maintenance: Patients receive vincristine IV on day 1, prednisone PO on days 1-5, mercaptopurine PO on days 1-28, and methotrexate PO weekly. Treatment occurs for up to 24 cycles or 2 years, whichever comes first, in the absence of disease progression or unacceptable toxicity.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Event-free survival
Time Frame: From randomization to failure to achieve measurable residual disease (MRD)-negative complete response (CR) after two cycles of chemotherapy, relapse, or death from any causes, assessed at 2 months (after 2 cycles of treatment)
Will be evaluated using the methods of Kaplan-Meier as well as Cox regression models.

Time Frame: From randomization to the time of death due to any cause, assessed up to 5 years
Will be evaluated using the methods of Kaplan-Meier as well as Cox regression models.
From randomization to the time of death due to any cause, assessed up to 5 years
Complete remission rate
Time Frame: Up to 5 years
The proportion of patients who achieve complete remission or any response to induction therapy will be summarized as the proportion of patients who achieve any type of response to induction therapy divided by the number of all evaluable patients registered to this trial and who received at least one dose of induction therapy. Corresponding 95% binomial confidence intervals will also be calculated. In a similar manner, the investigators will also evaluate the overall induction response rates. All evaluable patients will be used for this analysis.
Up to 5 years
Overall response rate
Time Frame: Up to 5 years
Overall response rate (CR/CRi, CR/complete remission with incomplete platelet counts [CRp], CR/complete remission with partial hematologic recovery [CRh]). The proportion of patients who achieve complete remission or any response to induction therapy will be summarized as the proportion of patients who achieve any type of response to induction therapy divided by the number of all evaluable patients registered to this trial and who received at least one dose of induction therapy. Corresponding 95% binomial confidence intervals will also be calculated. In a similar manner, the investigators will also evaluate the overall induction response rates. All evaluable patients will be used for this analysis.
Up to 5 years
MRD-negativity rate
Time Frame: Up to end of cycle 8 (1 cycle = 28 days)
MRD-negativity by flow cytometry will be evaluated at designated time point (after cycle 1, after cycle 2, end of intensive phase). Will also compare MRD assessment by centralized aspirate flow cytometry (Wood lab) to next generation sequencing (clonoSEQ, Adaptive) of blood and bone marrow at designated time points; and determine association with outcome.
Up to end of cycle 8 (1 cycle = 28 days)
Event-free survival
Time Frame: Up to 5 years
Event defined as failure to achieve Complete Response (CR)/Complete Remission with Incomplete Blood Count Recovery (CRi)/Complete Remission with Partial Hematological Recovery (CRh)/Complete Remission with Incomplete Platelet Counts (CRp), relapse, death.
Up to 5 years
Rate of grade 3-5 adverse events
Time Frame: Up to 5 years
The proportion of patients experiencing a grade 3+ adverse events or toxicities will be described for each treatment arm, but will also be compared between the arms using Fisher's exact tests.
Up to 5 years
