What the trial is, and whether it could suit you
This is a phase 2 clinical trial targeting pediatric and adolescent patients diagnosed with CD19-positive B-ALL, considered very high-risk group. The study aims to administer CD19 CAR-T therapy as an alternative to hematopoietic stem cell transplantation in patients eligible for such transplantation. The trial includes patients aged 25 or younger.

📋 Eligibility rules (as published)
Inclusion Criteria:
* Subject eligibility criteria include individuals who are under the age of 25 at the time of SNUH-CD19-CAR-T administration. Confirmation of B-cell acute lymphoblastic leukemia diagnosed at the initial assessment by a treating physician for the first diagnosis is required. Immunophenotypic analysis of CD19 expression on leukemia cells must be confirmed through immune profiling at the time of the initial diagnosis of B-cell acute lymphoblastic leukemia. In patients experiencing hematologic relapse of B-cell acute lymphoblastic leukemia, CD19 expression should also be confirmed at the time of relapse confirmation.
Patients must achieve hematologic complete remission defined as less than 5% blasts in the bone marrow after the first-line or second-line chemotherapy (first salvage therapy). Eligible patients for hematopoietic stem cell transplantation, defined by indications for transplantation, include those meeting at least one of the following criteria:
1. Philadelphia chromosome-positive due to t(9;22)(q34;q11) translocation.
2. Hypodiploidy defined by fewer than 44 chromosomes.
3. E2A-HLF gene fusion due to t(17;19) translocation.
4. Detection of minimal residual disease (MRD) positive at 0.01% or higher by next-generation sequencing confirmed after consolidation therapy and maintenance therapy.
5. Failure of the first-line therapy.
6. Cases not meeting any of the above criteria but deemed eligible for hematopoietic stem cell transplantation based on the investigator's judgment.
Exclusion Criteria:
* Patients who have undergone hematopoietic stem cell transplantation.
* Individuals for whom an adequate or sufficient leukapheresis product suitable for the production of SNUH-CD19-CAR-T cannot be obtained or is unavailable.
* Those known to be infected with the human immunodeficiency virus (HIV).
* Presence of uncontrolled active infections, determined by the investigator's assessment. If appropriate treatment has been administered for the infection, and there are no signs of progression at the time of enrollment, it is considered controlled. Persistent fever without other symptoms is not interpreted as progressive infection.
* Women who are pregnant or breastfeeding.
* Individuals deemed clinically inappropriate for participation in the clinical trial based on the investigator's clinical judgment.
