Clinical Study of Hospital-manufactured CD19 CAR-T in Children and Adolescents With Acute Lymphoblastic Leukemia

Q: Who can participate in NCT05210907?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

Q: How do I contact the trial site for NCT05210907?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Q: Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.

A Phase Ib, Clinical Trial of Hospital-manufactured CD19 Chimeric Antigen Receptor T Cells (SNUH-CD19-CAR-T) in Children and Adolescents With Relapsed or Refractory CD19 Positive Acute Lymphoblastic Leukemia

Clinical Study of Hospital-manufactured CD19 CAR-T in Children and Adolescents With Acute Lymphoblastic Leukemia (NCT05210907) is a Phase 1 interventional studying B-cell Acute Lymphoblastic Leukemia, sponsored by Seoul National University Hospital. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

Chimeric antigen receptor T cells (CAR-T cells) have been developed to treat relapsed and refractory hematological malignancies with promising outcome in patients with very poor prognosis. The purpose of this clinical study is to produce the CD19\[cluster of differentiation antigen 19\] CAR-T (SNUH-CD19-CAR-T) at the investigational site and to evaluate safety and efficacy of SNUH-CD19-CAR-T in children and adolescent with relapsed/refractory B-cell acute lymphoblastic leukemia.

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For B-cell Acute Lymphoblastic Leukemia, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 5 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Who May Qualify: - 1\. Relapsed or refractory CD19 Positive Acute Lymphoblastic Leukemia. All subjects must be younger than 26 years old at the time of obtaining willing to sign a consent form a. 2nd or greater BM\[bone marrow\] relapse OR b. Any BM relapse after allogeneic SCT\[stem cell transplant\] and must be ≥ 6 months from SCT at the time of SNUH\_CD19\_CAR-T infusion OR c .Refractory as defined by not achieving a CR after 2 cycles of a standard chemotherapy regimen or chemorefractory as defined by not achieving a CR after 1 cycle of standard chemotherapy for relapsed leukemia OR d. Ineligible for allogeneic SCT because of: - Severe comorbid disease - Other contraindications to allogeneic SCT conditioning regimen - Lack of suitable donor 2\. Documentation of CD19 tumor expression in bone marrow or peripheral blood by flow cytometry. 3\. Karnofsky (age ≥ 16 years) or Lansky (age \< 16 years) performance status ≥ 50 at screening Who Should NOT Join This Trial: 1. Evidence of uncontrolled hepatitis B virus (HBV) or hepatitis C virus (HCV) based on assessment done by treating physicians. 2. Known human weakened immune system virus (HIV) infection. 3. Presence of clinically active uncontrolled infection based on assessment done by treating physicians. Infections are considered controlled if appropriate therapy has been instituted and, at the time of screening, no signs of progression are present. Persisting fever without other signs or symptoms will not be interpreted as progressing infection. 4. Pregnant or nursing (lactating) women. Always talk to your doctor about whether this trial is right for you.
