A clinical study to provide the opportunity to be treated with CTL019, an investigational gene therapy, for children and adolescent patients with a recurrent form of B-cell acute lymphoblastic leukaemia after the closure of the Novartis single-arm phase II pivotal registration trial (Study CCTL019B2202) and to collect additional safety information.

Phase 1

Inclusion Criteria

Patients eligible for inclusion in this program have to meet all of the following criteria:
1. Relapsed or refractory B-cell ALL in pediatric or young adult patients
2. For relapsed patients, CD19 tumor expression demonstrated in bone marrow or peripheral blood by flow cytometry within 3 months of study entry with adequate organ function.
3. Adequate organ function as defined in the protocol.
4. Bone marrow with = 5% lymphoblasts by morphologic assessment at Screening
5. Life expectancy > 12 weeks.
6. Age < 26 years of age at the time of Screening.
7. Karnofsky (age = 16 years) or Lansky (age < 16 years) performance status = 50 at Screening.
8. Patients previously treated with blinatumomab who have detectable leukemia and documented CD19+ expression (via flow cytometry) and confirmed absence of CD19- leukemic blasts at Screening may be included.
9. Signed written informed consent form (ICF) and assent form if applicable must be obtained prior to any study procedures
10. Must meet the institutional criteria to undergo leukapheresis or have an acceptable, stored leukapheresis product.
11. Once all other eligibility criteria are confirmed, must have a leukapheresis product of nonmobilized cells received and accepted by
the manufacturing site. Note: Leukapheresis product will not be shipped to or assessed for acceptance by the manufacturing site until
documented confirmation of all other eligibility criteria is received.

Other protocol-defined inclusion criteria may apply.

Exclusion Criteria

Exclusion Criteria:
1. Isolated extra-medullary disease relapse.
2. Patients with concomitant genetic syndromes associated with bone marrow failure states: such as patients with Fanconi anemia, Kostmann syndrome, Shwachman syndrome or any other known bone marrow failure syndrome. Patients with Down Syndrome will not be excluded.
3. Patients with Burkitt's lymphoma/leukemia.
4. Prior malignancy, except carcinoma in situ of the skin or cervix treated with curative intent and with no evidence of active disease.
5. Prior treatment with any gene therapy product.
6. Prior treatment with any anti-CD19/anti-CD3 therapy, or any other anti-CD19 therapy, except for patients pre-treated with linatumomab
who fulfill inclusion criterion no. 8.
7. Presence of active or prior hepatitis B or C as indicated by serology (for detailed criteria see Appendix 2 of main protocol). Serology must be repeated, if the interval between testing at Screening and CTL019 infusion exceeds 8 weeks.
8. HIV positivity as indicated by serology. Serology must be repeated, if the interval between testing at Screening and CTL019 infusion exceeds 8 weeks.
9. Presence of grade 2 to 4 acute or extensive chronic graft versus host disease (GVHD).
10. Active CNS involvement by malignancy.
11. Uncontrolled acute life threatening bacterial, viral or fungal infection at Screening.
12. Previous or concurrent malignancy (exceptions defined in the protocol)
13. Intolerance to the excipients of the CTL019 cell product (i.e. dimethyl sulfoxide).
14. Cardiac or cardiac repolarization abnormality.
15. Patients enrolled in this study are not permitted to participate in additional parallel investigational drug or device studies.
16. Patient has an investigational medicinal product within the last 30 days prior to screening.
17. The following medications are excluded:
a. Steroids,
b. Allogeneic cellular therapy,
c. GVHD therapies,
d. Chemotherapy,
e. CNS disease prophylaxis,
f. Radiotherapy,
g. Anti-T cell antibodies.
18. Pregnant or nursing (lactating) women.
19. Women of child-bearing potential
20. Sexually active males must use a condom during intercourse while taking study treatment and for at least 12 months after the CTL019
infusion and until CAR T cells are no longer present by qPCR on 2 consecutive tests.

Other protocol-defined exclusion criteria may apply.
