3. Patient with relapsed or refractory CD19 positive B-acute lymphoblastic leukaemia (B-ALL).
4. Estimated life expectancy = 12 weeks (according to investigator’s judgement).
5. Eastern Cooperative Oncology Group (ECOG) performance status < 2
6. Adequate organ functions including renal and hepatic function based on the last assessment performed within the Screening Period, defined as:
- creatinine clearance = 30 mL/min (assessed as GFR using the Cockcroft & Gault formula)
- Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) < 3 x ULN (upper limit of normal)
- Total bilirubin < 1.5 x ULN (Except Gilbert’s Syndrome confirmed by UGT1A1 gene mutation)
7. Women of childbearing potential must have been tested negative in a serum pregnancy test within 7 days prior to inclusion.
8. Written informed consent obtained prior any study-specific procedure.

11. Foreseeable poor compliance to the study procedures.
12. Previous treatment with investigational gene or cell therapy medicine products.
13. Use of other investigational products or other anti-leukaemic therapy within 5 half-lives or within 14 days prior to UCART19 administration, whichever is a shorter duration, participation in non-interventional registries or epidemiological studies is allowed.
14. CD19 negative B-cell leukaemia.
16. Burkitt cell (L3 ALL) or mixed lineage acute leukaemia.

21. Autologous HSCT within 6 weeks or allogeneic HSCT within 3 months prior Screening.
22. Use of rituximab and other anti CD 20 antibodies known to have the same epitope as rituximab or anti CD20 for which the epitope is unknown within 6 months prior to Screening.
23. Presence of donor-specific anti-HLA antibodies.
24. Active acute or chronic GvHD requiring therapy.
25. Patient with autoimmune disease treated with immunosuppressive agents, e.g. corticosteroids > 1 mg/kg, within 5 days prior to administration of UCART19. Infliximab must be stopped at least 45 days prior to administration of UCART19.

30. Any major surgery within 3 months prior to Screening.
31. Abnormal findings during the Screening period, any other medical condition(s) or laboratory findings that, in the opinion of the investigator, might jeopardize the patient’s safety.
32. Any planned medical/surgical treatment that might interfere with the ability to comply with the study requirements.
33. Evidence of another malignancy within 2 years prior to Screening (except in situ basal or squamous cervix or skin cell carcinoma).
34. Any mental condition rendering the patient unable to understand the nature, scope and possible consequences of the study, and/or evidence of an uncooperative attitude.
