Brief Summary
This phase II trial tests the safety and effectiveness of giving chemotherapy with or without venetoclax and/or navitoclax for the treatment of patients with newly diagnosed T-cell acute lymphoblastic leukemia (T-ALL) or T-cell lymphoblastic lymphoma (T-LBL). 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. Venetoclax and navitoclax are in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. They may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving chemotherapy with or without venetoclax and/or navitoclax may be effective treatments for patients with newly diagnosed T-ALL or T-LBL.

Outcome Measures
Primary Outcomes (4)
Incidence of adverse events (Cohorts 1, 2 and 3)
National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events will be used to determine severity of toxicity.
Up to 10 years
Undetectable minimal residual disease (MRD) (Cohort 1)
There will be three primary analyses, each comparing an experimental arm with the shared control arm using Fisher's exact test with a one-sided alpha of 10%. All eligible randomized participants will be used in the efficacy comparison.
At day 29 following induction
Percent of participants with detectable disease in the bone marrow (Cohort 2)
Binomial estimates will be reported along with exact 95% confidence intervals.
At diagnosis and at days 29 and 57
Undetectable MRD (Cohorts 1 and 3)
Binomial estimates will be reported along with exact 95% confidence intervals.
At days 29 and 78
Secondary Outcomes (8)
Rate of complete remission (CR)
End of consolidation therapy
Rate of complete remission with incomplete count recovery (CRi) with and without MRD
End of consolidation therapy
Event free survival
From the date of initial registration on study until the first of the following events: death from any cause, relapse from MRD-negative remission, or completion of protocol therapy without documentation of MRD-negative remission, up to 10 years
Relapse free survival
From the date the participant first achieves CR or CRi until relapse from CR/CRi or death from any cause, up to 10 years
Overall survival
From the day of registration to death from any cause, up to 10 years
- +3 more secondary outcomes
Other Outcomes (3)
Rates of MRD
At day 29 (all cohorts), day 78 (cohorts 1 and 3), and day 57 (cohort 2)
Percentage of participants with ETP and non-ETP immunophenotype
Diagnosis
Association of CR/CRi, event-free survival, relapse-free survival, and overall survival with early thymic precursor (ETP) and non-ETP immunophenotype
Up to 10 years

Eligibility Criteria
You may qualify if:
- Participants must have newly diagnosed T-cell acute lymphoblastic leukemia (T-ALL) or T-lineage lymphoblastic lymphoma (T-LBL) based on 2022 World Health Organization (WHO) criteria. Participants with acute leukemia of ambiguous lineage (ALAL), including mixed phenotype acute leukemia (MPAL), are not eligible for this trial
- For T-ALL, immunophenotyping of the blood or marrow lymphoblasts must be performed by flow cytometry to confirm T-cell lineage and exclude ALAL or MPAL. Appropriate lineage-specific antigens include cytoplasmic or surface CD3 for T lineage, myeloperoxidase (MPO) or monocytic antigens (CD11c, CD14, CD64, lysozyme) for myeloid lineage, and CD19, CD20, CD22, CD79a, CD10 and PAX5 for B lineage. For T-LBL, immunohistochemistry on paraffin embedded tissue alone can be used to establish the diagnosis, although flow cytometry is preferred
- NOTE: Systemic chemotherapy must begin within 72 hours of first dose of intrathecal therapy
- Collection of pretreatment blood and bone marrow specimens must be completed within 14 days prior to registration for all participants. If bone marrow is unable to be aspirated and blood blast percentage is at least 5%, additional blood should be collected as instructed in the study calendar
- Participants must not have received prior induction chemotherapy for T-ALL/LBL. Prior treatments with hydroxyurea, all-trans retinoic acid (ATRA), corticosteroids, leukapheresis to reduce peripheral blast count and prevent complications from leukocytosis, and a single dose of intrathecal cytarabine and/or methotrexate with or without steroids are permitted
- Participants must discontinue strong CYP3A4 inducers within 7 days prior to registration. Dose adjustments for CYP3A4 inhibitors/inducers during protocol therapy are defined in the protocol
- Participants must be 18-60 years old
- Participants must have Zubrod/Eastern Cooperative Oncology Group (ECOG performance status of 0-2
- Participants must have a complete medical history and physical exam within 28 days prior to registration
- Participants with extramedullary disease at diagnosis must have a CT scan with contrast of chest, neck, abdomen, pelvis, or whole body to obtain baseline values within 28 days prior to registration
- Total bilirubin ≤ 1.5 institutional upper limit of normal (ULN). Participants with history of Gilbert's disease or leukemia involving the liver must have total bilirubin ≤ 5 x institutional ULN within 7 days prior to registration
- Aspartate aminotransferase (AST)/ Alanine aminotransferase (ALT) Both must be ≤ 3 × institutional ULN unless related to leukemia involving the liver
- Participants must have a serum creatinine 1.5 ≤ the ULN OR measured OR calculated creatinine clearance ≥ 50 mL/min using the Cockcroft-Gault Formula. This specimen must have been drawn and processed within 7 days prior to registration
- Participants must have a lumbar puncture to determine CNS involvement of ALL within 14 days prior to registration. Intrathecal cytarabine and/or methotrexate administered prior to study registration may count as the first dose of intrathecal therapy required as part of protocol therapy
- Participants must have cardiac ejection fraction \>= 50% by MUGA or 2-D echocardiogram within 28 days before registration. Participants with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, must have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, participants must be class 2B or better
