This prospective, randomized, controlled trial evaluates the efficacy and safety of a new targeted drug combined with chemotherapy versus standard chemotherapy alone. Eligible patients were randomized 1:1 to either the treatment or control group.

This study is a prospective, randomized, controlled clinical trial aimed at evaluating the efficacy and safety of the new targeted drug combined with chemotherapy. After signing the informed consent form, patients who met the inclusion/exclusion criteria were randomly assigned to the treatment group and the control group at a ratio of 1:1. Both groups of subjects received standard induction chemotherapy in the first course. Patients in the treatment group would receive corresponding targeted drug combined chemotherapy based on bone marrow PCR testing, while patients in the control group would receive standard chemotherapy. Both the treatment group and the control group would select subsequent treatments based on the chemotherapy efficacy of the subjects. Each subject would undergo regular bone marrow examinations and other evaluations for the underlying disease on a regular basis.

Inclusion Criteria:

1. The subjects were diagnosed with acute T-lymphocytic leukemia (according to the 2016 WHO classification) based on their bone marrow pathology and hematology, and sufficient bone marrow samples were available for PCR analysis;
2. The subjects must have never received anti-leukemia treatment before;
3. Age ≥ 18 years old, gender not restricted;
4. The subjects' Eastern Cooperative Oncology Group (ECOG) performance status score is 0-2;
5. The subjects or their legal representatives must provide written informed consent before undergoing the special examinations or procedures of the study.

Exclusion Criteria:

1. Classified as other types of leukemia according to the WHO 2016 classification;
2. Previously received systemic or local treatments including chemotherapy;
3. Previously underwent hematopoietic stem cell transplantation;
4. Had other tumors in addition to leukemia;
5. Had uncontrolled cardiovascular and cerebrovascular diseases, coagulation disorders, severe infectious diseases, etc.;
6. Patients with a history of allergic reactions to any drugs in this research protocol;
7. Left ventricular ejection fraction ≤ 50%;
8. Laboratory test values at screening (unless caused by leukemia): ALT or AST higher than twice the upper limit of normal, AKP and bilirubin higher than 1.5 times the upper limit of normal, creatinine level higher than 1.5 times the upper limit of normal;
9. Other concurrent and uncontrolled medical conditions that the researcher considers will affect the patient's participation in the study;
10. Psychiatric patients or other patients known or suspected to be unable to fully comply with the study protocol;
11. Pregnant or lactating women;
12. HIV-infected individuals.
