Engineered immune cells take aim at stubborn childhood leukemia
NCT ID NCT03876769
First seen Jun 25, 2026 · Last updated Aug 20, 2026 · Updated 4 times
Summary
This phase II trial tests a personalized cell therapy called tisagenlecleucel (Kymriah) in children and young adults with high-risk B-cell acute lymphoblastic leukemia who still have detectable cancer cells after initial chemotherapy. The treatment involves collecting the patient's own immune cells, genetically modifying them to recognize and attack leukemia cells, and infusing them back. The study aims to see if this approach can prevent relapse and improve survival without needing a stem cell transplant.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tisagenlecleucel (a CAR-T cell therapy made from the patient's own immune cells)
- What this could lead to
- If successful, this could offer a way to eliminate remaining leukemia cells without needing a stem cell transplant, potentially improving long-term survival.
- What could go wrong
- This is a phase II trial with 121 participants, so results are still preliminary. CAR-T therapy can cause serious side effects like cytokine release syndrome and neurological problems.

Inclusion Criteria: 1. CD19 expressing B-cell Acute Lymphoblastic Leukemia 2. De novo NCI HR B-ALL who received first-line treatment and are MRD ≥ 0.01% at EOC. EOC bone marrow MRD will be collected prior to screening and will be assessed by multi-parameter flow cytometry using central laboratory analysis. 3. Age 1 to 25 years at the time of screening 4. Lansky (age \< 16 years) or Karnofsky (age ≥ 16 years) performance status ≥ 60% 5. Adequate organ function during the screening period: A. Renal function based on age/gender B. ALT ≤ 5 times ULN for age C. AST ≤ 5 times ULN for age D. Total bilirubin \< 2 mg/dL (for Gilbert's Syndrome subjects total bilirubin \< 4 mg/dL) E. Adequate pulmonary function defined as: * no or mild dyspnea (≤ Grade 1) * oxygen saturation of \> 90% on room air F. Adequate cardiac function defined as LVSF ≥ 28% confirmed by echocardiogram or LVEF ≥ 45% confirmed by echocardiogram or MUGA within 6 weeks of screening 6. Prior induction and consolidation chemotherapy allowed: 1st line subjects: ≤ 3 blocks of standard chemotherapy for first-line B-ALL, defined as 4-drug induction, Berlin-Frankfurt-Münster (BFM) consolidation or Phase 1b, and interim maintenance with high-dose methotrexate. Exclusion Criteria: 1. M3 marrow at the completion of 1st line induction therapy 2. M2 or M3 marrow or persistent extramedullary disease at the completion of first-line consolidation therapy or evidence of disease progression in the peripheral blood or new extramedullary disease prior to enrollment. Patients with previous CNS disease are eligible if there is no active CNS involvement of leukemia at the time of screening. 3. Philadelphia chromosome positive ALL 4. Hypodiploid: less than 44 chromosomes and/or DNA index \< 0.81, or other clear evidence of a hypodiploid clone 5. Prior tyrosine kinase inhibitor therapy 6. Subjects with concomitant genetic syndromes associated with bone marrow failure states: such as subjects with Fanconi anemia, Kostmann syndrome, Shwachman syndrome or any other known bone marrow failure syndrome. Subjects with Down syndrome will not be excluded. 7. Subjects with Burkitt's lymphoma/leukemia (i.e. subjects with mature B-ALL, leukemia with B-cell \[sIg positive and kappa or lambda restricted positivity\] ALL, with FAB L3 morphology and /or a MYC translocation) 8. Has had treatment with any prior anti-CD19 therapy 9. Treatment with any prior gene or engineered T cell therapy Other protocol-defined inclusion/exclusion may apply.
