About this study
Official title: Evaluating the Efficacy of Venetoclax Combined With Azacitidine Induction Therapy of Early T-cell Precursor-like Acute Lymphoblastic Leukemia and T-ALL With Myeloid Mutations
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).
Read the detailed description
This study addresses the unmet need for effective therapies in high-risk T-ALL subtypes, including ETP-like leukemia and T/My-MPAL, which exhibit myeloid-like genetic profiles (e.g., FLT3, DNMT3A, RUNX1 mutations) and poor outcomes under conventional chemotherapy (5-year OS <40%). Preclinical and pilot clinical data demonstrate that venetoclax, a BCL-2 inhibitor, synergizes with azacitidine, a hypomethylating agent, to induce apoptosis in leukemia stem cells by targeting oxidative phosphorylation and epigenetic dysregulation. Building on a pilot study, this Phase II trial employs a single-arm design to validate efficacy in a larger cohort.
Patients receive two induction cycles of venetoclax (oral, 100 mg D1, 200 mg D2, 400 mg D3-28) and azacitidine (75 mg/m² SC D1-7), with response assessed via bone marrow morphology, flow cytometry, and molecular testing (Days 22-35).
Early Efficacy Evaluation: After the first induction cycle (Days 22-35), response is assessed via bone marrow morphology, flow cytometry, and molecular profiling.
Stopping Criteria:
Patients failing to achieve at least partial remission (PR) after Cycle 1 will be withdrawn from the study.
Patients failing to achieve CR or CRi at the end of Cycle 2 will also discontinue study treatment.
Consolidation strategies include allo-HSCT or high dose cytarabine (HiDAC) for fit patients or maintenance therapy for unfit individuals.
Rigorous safety monitoring follows NCI-CTCAE v5.0 criteria, with dose adjustments for hematologic/non-hematologic toxicities.
Statistical analysis includes intent-to-treat and per-protocol populations, with ORR analyzed via exact binomial tests and survival endpoints via Kaplan-Meier/Cox regression. The study integrates translational biomarkers (e.g., BCL-2 expression, mutational profiling) to identify predictors of response, aiming to establish a novel, mechanism-driven regimen for these aggressive leukemias.

| Investigational ( venetoclax, azacytidine) | Experimental | Two cycles induction as venetoclax (oral, 100 mg D1, 200 mg D2, 400 mg D3-28) and azacitidine (75 mg/m² SC D1-7); Consolidation: For fit patients, if those with MRD (Minimal Residual Disease) are negative or refuse to undergo allo-HSCT (Hematopoietic stem-cell transplantation), intermediate-dose (2g/m² q12h, days 1-3) cytarabine-based therapy is administered for 3-4 cycles; if patients are MRD-positive, they undergo allo-HSCT.
For unfit patients, each venetoclax combined with azacitidine treatment cycle is anticipated to be 28 days in length until progression of disease, although cycle delays may occur due to delayed blood count recovery. Receives: Drug: Venetoclax; Drug: Azacitidine; Drug: Cytarabine |

What is this clinical trial studying?
A Phase 2 study testing Venetoclax, Azacitidine and Cytarabine in people with Early T Acute Lymphoblastic Leukemia and T-Acute Lymphoblastic Leukemia, run by yuejun Liu at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 10 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Yue-jun Liu (008613915535177, liuyuejun@suda.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall response rate (ORR) after two treatment cycles of induction therapy (time frame: time from the date of enrollment to 2 cycles of induction before consolidation therapy（100 days）). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jun 2025; AzTrials last refreshed its copy on 8 Nov 2026.
