Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In recent years, immunotherapy (eg. blinatumomab, inotuzumab ozogamicin, CAR-T cells) has demonstrated a high safety and efficacy profile in relapsed/refractory (R/R)B-ALL. The available data suggest that the advancement of immunotherapy from relapsed/refractory (R/R) field to the frontline setting may be an important approach to increase the depth of remission, which ultimately translates into a survival benefit. In this study, the investigators propose a treatment regimen using CAR-T cell therapy as a consolidation method for Ph- B-ALL patients achieving complete remission (CR) with chemotherapy, aiming to reduce the total cycles of chemotherapy and related toxicities, shorten length of hospitalization, and ultimately improve patients' survival and quality of life.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The CAR-T cells were murine-derived second-generation CD19 CAR-T with a co-stimulation domain of 4-1BB, and the infusion dose was 1×10\^6/kg CAR+ cells in a single infusion.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. De novo and primary Ph/BCR-ABL1 negative acute lymphoblastic leukemia diagnosed by the bone marrow cytomorphology, immunophenotyping, cytogenetics and molecular biology according to WHO classification
2. Male or female patients aged 18 years or older
3. CD19 expression on blasts
4. Expected survival time greater than 3 months
5. Adequate end organ function as defined by: Total bilirubin ≤ 1.5 x upper limit of normal(ULN); serum alanine aminotransferase (ALT) and serum aspartate aminotransferase (AST) ≤ 2.5 x ULN or ≤5 x ULN if leukemic involvement of the liver is present; Creatinine ≤ 1.5 x ULN; Serum amylase and lipase ≤ 1.5 x ULN; Alkaline phosphatase ≤ 2.5 x ULN unless considered tumor related; normal electrolytes: Potassium ≥ LLN; Magnesium ≥ LLN; Phosphorus ≥ LLN; Cardiac color Doppler ultrasound ejection fraction ≥ 45%
6. Subject has provided written informed consent prior to any screening procedure

Exclusion Criteria

1. Burkitt lymphoma/leukemia
2. Acute Leukemia of Ambiguous Lineage
3. Clinical manifestations of active CNS or extramedullary involvement with ALL
4. Female patients who are pregnant or breast feeding
5. Uncontrolled active serious infections that could, in the investigator's opinion, potentially interfere with the completion of treatment
6. Known HIV seropositivity
7. Clinically significant ventricular arrhythmias, unexplained syncope (not vasovagal) or sinus block, history of chronic bradycardia with a high degree of atrioventricular (AV) conduction block (unless a permanent pacemaker is implanted)
