What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 36 participants in total. It began in 2024-12 with a primary completion date of 2025-12-30.

Brief Summary

Precursor B cell acute lymphoblastic leukemia (B-ALL) is an aggressive type of leukemia, with high relapse rate and poor long term survival in adults. Philadelphia chromosome positive (Ph+) ALL is defined as ALL with translocation between chromosomes 9 and 22. And t(9;22)(q34;q11) is the most common chromosomal abnormality in ALL. Before the emergence of TKI, the prognosis of Ph+ ALL was extremely poor, and the long-term survival rate was only 10%-35%. Ph+ ALL accounts for about 30% of adult ALL. In this study, the investigators propose a treatment approach that combines Venetoclax with Olverembatinib and Predinisone in Ph+ B-ALL adults. The study aims to answer the safety and efficacy of this treatment regimen, and further improve the survival for those participants.

Eligibility Criteria

Inclusion Criteria: 1. Before enrollment, the patient must be diagnosed with de novo precursor B-cell acute lymphoblastic leukemia and positive for Philadelphia chromosome (presence of t(9;22) and/or BCR::ABL1 positive and/or FISH positive). The diagnostic criteria refer to the 2022 WHO classification; 2. Age ≥ 18 years; 3. Eastern Cooperative Oncology Group (ECOG) performance status score of 0-2; 4. Expected survival time ≥ 3 months; 5. No organ dysfunction that would restrict the use of this protocol during the screening period; 6. Understand the study and sign the informed consent form. 7. Men, women of childbearing age (only postmenopausal women who have been menopausal for at least 12 months can be considered infertile), and their partners voluntarily take effective contraceptive measures deemed effective by the investigator during the treatment period and for at least 12 months after the last dose of the study drug. Exclusion Criteria: 1. Accelerated phase or blast crisis of chronic myeloid leukemia; 2. Subjects with involvement of the central nervous system (CNS) or accompanied by extramedullary lesions; 3. Subjects who have received systemic anti-leukemia treatment (including but not limited to TKI, radiotherapy or chemotherapy, except for the allowed pretreatment); 4. Subjects with a history of myocardial infarction within 12 months, or have clinical manifestations of heart disease (including but not limited to unstable angina pectoris, congestive heart failure, uncontrolled hypertension and uncontrolled arrhythmia, etc.); left ventricular ejection fraction (LVEF) on echocardiography \<50%; 5. Diseases with abnormal functions of organs such as lung, liver, and kidney that may limit the patient's participation in this trial (including but not limited to severe infection, uncontrolled diabetes, active tuberculosis, asthma, COPD, bronchiectasis, etc.); 6. History of other malignancies within the past 5 years, excluding localized thyroid cancer and in situ skin cancer; 7. Serum total bilirubin \> 1.5 ULN (upper limit of normal); ALT or AST \> 2.5 ULN; serum creatinine \> 1.5 ULN; 8. Known HIV infection; 9. Conditions affecting the use of the study drug as assessed by the investigator; 10. Unable to understand or comply with the study protocol.
