PRIMARY OBJECTIVES:
I. To evaluate if the end of induction minimal residual disease (MRD)-negative rate is higher in patients with T-ALL treated with dasatinib compared to similar patients treated with 4-drug induction on AALL1231.
II. To evaluate if the end of induction MRD-negative rate is higher in patients with early T precursor (ETP) or near-ETP ALL treated with venetoclax compared to similar patients treated with 4-drug induction on AALL1231.
SECONDARY OBJECTIVES:
I. To assess the event free and overall survival of patients treated with this therapy.
II. To compare grade 4 toxicities, event-free survival (EFS) and overall survival (OS) of patients treated with this therapy in induction and re-induction to toxicities of similar patients treated on TOT17.
EXPLORATORY OBJECTIVES:
I. To describe response patterns in patients with T-acute lymphoblastic lymphoma (T-LLy) treated with this therapy.
II. To describe response patterns in patients with mixed phenotype acute leukemia/lymphoma (MPAL) treated with this therapy.
III. To describe the kinetics of high-throughput sequencing (HTS)- based MRD response during therapy to that of MRD assessed by flow cytometry using bulk tumor, single cell and cell free genomic approaches.
IV. To assess the impact of germline and somatic variants on treatment response and toxicity.
V. To compare network-based Bayesian inference of drivers (NETBID) and pharmacotyping predicted dasatinib and venetoclax sensitivity to response to treatment.
VI. To assess the impact of this therapy on neurocognitive and quality of life outcomes.
