Testing the Addition of the Anti-cancer Drug Venetoclax and/or the Anti-cancer Immunotherapy Blinatumomab to the Usual Chemotherapy Treatment for Infants With Newly Diagnosed KMT2A-rearranged or KMT2A-non-rearranged Leukemia

A Phase 2 Study of Blinatumomab in Combination With Chemotherapy for Infants With Newly Diagnosed Acute Lymphoblastic Leukemia With Randomization of KMT2A-Rearranged Patients to Addition of Venetoclax

This phase II trial tests the addition of venetoclax and/or blinatumomab to usual chemotherapy for treating infants with newly diagnosed acute lymphoblastic leukemia (ALL) with a KMT2A gene rearrangement (KMT2A-rearranged [R]) or without a KMT2A gene rearrangement (KMT2A-germline [G]). Venetoclax is in a class of medications called B-cell lymphoma-2 (Bcl-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Blinatumomab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. 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. Adding venetoclax and/or blinatumomab to standard chemotherapy may be more effective at treating patients with ALL than standard chemotherapy alone, but it may also cause more side effects. This clinical trial evaluates the safety and effectiveness of adding venetoclax and/or blinatumomab to chemotherapy for the treatment of infants with KMT2A-R or KMT2A-G ALL.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Child
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

• All patients must be enrolled on APEC14B1 and consented to eligibility screening (part A) prior to treatment and enrollment on AALL2321
• Infants (aged 365 days or less) on the date of diagnosis are eligible; infants must be > 36 weeks gestational age at the time of enrollment

• Patients must have newly diagnosed B-acute lymphoblastic leukemia (B-ALL, 2017 World Health Organization [WHO] classification), also termed B-precursor ALL, or acute leukemia of ambiguous lineage (ALAL), which includes mixed phenotype acute leukemia. For patients with ALAL, the immunophenotype of the leukemia must comprise at least 50% B lineage

  • Diagnostic immunophenotype: Leukemia cells must express CD19

Exclusion Criteria:

• Patients with Down Syndrome
• Patients with secondary B-ALL that developed after treatment of a prior malignancy with cytotoxic chemotherapy

• Patients must not have received any cytotoxic chemotherapy for either the current diagnosis of infant ALL or for any cancer diagnosis prior to the initiation of protocol therapy, with the exception of:

  • Steroid pretreatment:

    • PredniSONE, prednisoLONE, or methylPREDNISolone for ≤ 72 hours (3 days) in the 7 days prior to enrollment. The dose of predniSONE, prednisoLONE or methylPREDNISolone does not affect eligibility
    • Inhaled and topical steroids are not considered pretreatment
    • Note: Pretreatment with dexamethasone in the 28 days prior to initiation of protocol therapy is not allowed with the exception of a single dose of dexamethasone used during or within 6 hours prior to or after sedation to prevent or treat airway edema. However, prior exposure to ANY steroids that occurred > 28 days before enrollment does not affect eligibility

  • Intrathecal cytarabine or methotrexate:

    • An intrathecal dose of cytarabine or methotrexate in the 7 days prior to enrollment does not affect eligibility
    • Note: The preference is to defer the diagnostic lumbar puncture with intrathecal chemotherapy to day 1 of induction to allow for cytoreduction of circulating blasts and decrease the potential for central nervous system (CNS) contamination due to a traumatic tap. If done prior to day 1 of induction, these results will be used to determine CNS status

  • Hydroxyurea:

    • Pretreatment with ≤ 72 hours (3 days) of hydroxyurea in the 7 days prior to enrollment does not affect eligibility
• All patients and/or their parents or legal guardians must sign a written informed consent
• All institutional, Food and Drug Administration (FDA) and National Cancer Institute (NCI) requirements for human studies must be met

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Incidence of dose-limiting toxicities (DLTs) (safety phase)		For the duration of the induction + venetoclax cycle
Incidence of DLTs (expansion phase)	For the expansion phase, DLTs of Arm B will be assessed and monitored for the cycles that contain venetoclax (induction, consolidation, and MARMA cycles of Arm B).	During the induction, consolidation, and MARMA cycles
Minimal residual disease (MRD)-negative remission rate	The end of induction MRD-negative remission rate will be compared between Arm A and Arm B. MRD negativity is defined as achievement of complete remission and MRD < 0.01% by flow cytometry. The MRD-negative remission rate at the end of induction between Arm A and Arm B will be compared using a one-sided Z test of proportions with Type I error of 0.15.	At the end of induction

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Event free survival (EFS) rates of infants with KMT2A-R acute lymphoblastic leukemia (ALL)	The EFS rates from date of randomization of Arm B will be compared to Arm A. Comparison of EFS rates between Arm A and Arm B will be based on a one-sided logrank test with Type I error of 0.15.	From date of randomization to treatment failure, first documented relapse following achievement of remission-1, occurrence of a second or secondary malignant neoplasm, or death, assessed up to 3 years
3-year EFS of infants with KMT2A-R ALL	For Arm A, the 3-year EFS rate (representing a plateau rate based on the shape of EFS curves of historical data in this patient population) from the date of randomization will be compared to the stable historical 3-year EFS rate of 35% observed in AALL0631 and other international trials.	From date of randomization to treatment failure, first documented relapse following achievement of remission-1, occurrence of a second or secondary malignant neoplasm, or death, assessed up to 3 years
Proportion of KMT2A-G patients in Arm C who are able to receive all treatment cycles before maintenance	The feasibility of treating of KMT2A-G patients with a high-risk ALL backbone and two cycles of blinatumomab (Arm C) will be assessed. Arm C treatment will be considered feasible for KMT2A-G patients if the proportion of KMT2A-G patients in Arm C who are able to receive all treatment cycles before maintenance (i.e., up to interim maintenance 2) is more than 76.8%. The proportion of patients receiving all cycles before Maintenance will be compared to 76.8% with a one-sample exact test of proportion with Type I error of 0.15.	Up to interim maintenance 2
Pharmacokinetics (PK) of venetoclax in infants	PK samples will be collected from patients enrolled in the safety phase of the study as well as from patients randomized to Arm B in the expansion phase who consent to participate, to determine the major secondary objective of characterizing the PK of venetoclax in infants. PK samples will be evaluated in batches and standard nonlinear mixed effect modeling will be used for model building and refinement of time-concentration data. After model refinement, a non-parametric bootstrap analysis will be performed reporting the 95% confidence intervals for each PK parameter.	On days 7, 10, and 14 of induction

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
3-year EFS of infants with KMT2A-R ALL treated on Arm B	Summary statistics will be calculated. When appropriate, comparisons of the endpoints will be conducted between patients who achieved MRD-negative remission vs those who did not, between arms, or between patients with different baseline characteristics. Analyses will be descriptive and exploratory. Arm B will be compared to Arm A as described above and to historical 3-year EFS. Comparison will be based on a one-sample test of proportion with one-sided Type I error of 0.15.	From date of randomization to treatment failure, first documented relapse following achievement of remission-1, occurrence of a second or secondary malignant neoplasm, or death, assessed up to 3 years
3-year EFS of infants with KMT2A-G ALL treated on Arm C	Summary statistics will be calculated. When appropriate, comparisons of the endpoints will be conducted between patients who achieved MRD-negative remission vs those who did not, between arms, or between patients with different baseline characteristics. Analyses will be descriptive and exploratory. The 3-year EFS rate from date of enrollment of KMT2A-G patients in Arm C will be estimated with the Kaplan-Meier method.	From date of randomization to treatment failure, first documented relapse following achievement of remission-1, occurrence of a second or secondary malignant neoplasm, or death, assessed up to 3 years
Use of high-throughput sequencing (HTS) for MRD detection in infant ALL compared to centralized flow cytometry	Pre-treatment HTS clonality and HTS MRD tracking results will be collected and compared to the required centralized flow cytometry-based MRD data to evaluate the feasibility and prognostic utility of HTS MRD evaluation in the infant ALL population.	Up to 3 years
PK of calaspargase pegol in infants with ALL	PK of calaspargase pegol will be analyzed by monitoring asparaginase activity levels. Once a PK model is developed for calaspargase pegol, standard regression analysis will be used to describe the relationship between drug exposure and asparaginase activity. Additionally, asparaginase-associated toxicities will be described for the entire study population and correlated with activity levels when possible. The result of this analysis will be an estimation of potential optimal exposure expected to yield the maximum efficacy while limiting toxicity. These analyses will be exploratory and descriptive.	At completion of the trial, up to 3 years
Incidence of CD19-negative relapse and myeloid switch relapse with protocol therapy	For patients who experience relapse, will collect information regarding the immunophenotype of the leukemic blasts at time of relapse. Will report on the rate of CD19 negative relapse as well as myeloid switch relapse for all patients enrolled on study. This analysis will be exploratory and descriptive.	At the time of relapse, up to 3 years
Impact of venetoclax in combination with chemotherapy on T-cell subsets and function	BCL-2 inhibition is reported to alter T-cell subsets, including increased activation, enhanced cytotoxicity against leukemia cells and heightened resistance to cell death. Peripheral blood and bone marrow samples will be collected prior to and following the first course of venetoclax to evaluate effects on T-cell subsets and function following venetoclax exposure.	Prior to and following the first course of venetoclax
Feasibility of T-cell collection and success of T-cell manufacturing for infants with KMT2A-R ALL who receive chimeric antigen receptor T-cell therapy	For patients that undergo T-cell collection, will collect data regarding the feasibility of T-cell collection in the context of protocol therapy. Additionally, for patients who proceed with CAR T-cell therapy after coming off protocol therapy, will collect data regarding the success of T-cell manufacturing, infusion and response to therapy in this young population, as the success of this subsequent therapy may be heavily impacted by the effect of protocol therapy on T-cell function. These analyses will be exploratory and descriptive.	After coming off protocol therapy
Predictors of response and resistance to venetoclax and overall protocol therapy	Will study the inter- and intra- patient variability in the expression of apoptotic proteins (e.g., BCL-2, MCL-1, BCL-XL) and apoptotic priming at diagnosis and identify changes that occur during induction therapy in relationship to venetoclax exposure. Will then determine whether the state of BCL-2 specific apoptotic priming correlates with outcome. Will also integrate genomic and molecular features (such as developmental state, signaling, epigenomic, transcriptomic, proteomic and metabolomic states) before and after venetoclax exposure, for those assays where this type of analysis is feasible, to determine biomarkers of response and resistance to therapy for infants with ALL.	Before and after venetoclax exposure, up to 3 years
Impact of subsequent anti-cancer therapy on overall survival	For all patients who remain in study follow-up after coming off protocol therapy, data will be collected regarding subsequent cancer directed therapies received as well as relapse and survival status in order to evaluate the impact of subsequent cancer directed therapy on the overall survival of patients enrolled on this study. These analyses will be exploratory and descriptive.	After coming off protocol therapy
