Brief Summary

This is a single arm, open-label, multi-center, phase II study to determine the efficacy and safety of tisagenlecleucel in de novo HR pediatric and young adult B-ALL patients who received first-line t...

Eligibility Criteria

Inclusion

  • CD19 expressing B-cell Acute Lymphoblastic Leukemia
  • 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.
  • Age 1 to 25 years at the time of screening
  • Lansky (age \< 16 years) or Karnofsky (age ≥ 16 years) performance status ≥ 60%
  • 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
  • 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

  • M3 marrow at the completion of 1st line induction therapy
  • 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.
  • Philadelphia chromosome positive ALL
  • Hypodiploid: less than 44 chromosomes and/or DNA index \< 0.81, or other clear evidence of a hypodiploid clone
  • Prior tyrosine kinase inhibitor therapy
  • 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.
  • 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)
  • 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.
