The goal of this clinical trial is to evaluate the efficacy and safety of venetoclax combined with azacitidine in treating newly diagnosed early T-cell precursor (ETP)-like acute lymphoblastic leukemia (ALL), T-ALL with myeloid mutations, or T/myeloid mixed-phenotype acute leukemia (T/My-MPAL).
Participant population: Patients aged ≥14 years diagnosed with ETP-like leukemia, T-ALL with myeloid mutations, or T/My-MPAL, regardless of sex/gender.
The main question it aims to answer: Does venetoclax plus azacitidine achieve a significantly higher overall response rate (ORR: CR + CRi) compared to historical controls (54% vs. 90%) after two induction cycles?
Comparison group: Researchers will compare ORR outcomes to historical data from conventional chemotherapy regimens to assess treatment superiority.
Participants will:
* Receive two 28-day cycles of venetoclax (oral, 100 mg D1, 200 mg D2, 400 mg D3-28) and azacitidine (75 mg/m²/day SC, D1-7). * Undergo serial bone marrow biopsies, blood tests, and imaging (e.g., PET-CT) for response assessment. * Follow dose adjustment protocols for toxicity management (e.g., neutropenia, thrombocytopenia).
