|Condition or disease||Intervention/treatment||Phase|
|B-cell Acute Lymphoblastic Leukemia||Biological: CTL019||Phase 2|
This was a initially a one cohort, open-label, multi-center, phase II study to determine the efficacy and safety of CTL019 in pediatric patients with r/r B-cell ALL. This main cohort completed enrollment. Two new cohorts were added via an amendment, Cohort 1 for high risk B-cell ALL patients at first relapse, and Cohort 2 for feasibility and safety of CTL019 in high risk B-cell ALL in patients that relapsed <6 months post allo-HSCT. Due to lack of recruitment, both of these cohorts have halted recruitment. This decision was not related to any safety issue.
The study had the following sequential phases: Screening, Pre-Treatment (Cell Product Preparation & Lymphodepleting Chemotherapy), Treatment and Primary Follow-up, Secondary Follow-up (if applicable) and Survival Follow-up. The total duration of the study is 5 years from CTL019 cell infusion.

Experimental: Single dose of CTL019
Pediatric patients with relapsed or refractory B-cell ALL who were treated with single dose of tisagenlecleucel (CTL019).
Tisagenlecleucel was administered as a single iv infusion. Dose: 2.0 to 5.0x106 tisagenlecleucel per kg body weight (for patients ≤ 50 kg) or 1.0 to 2.5x108 tisagenlecleucel (for patients >50 kg).
- Percentage of Participants With Overall Remission Rate (ORR) as Determined by IRC Assessment. [ Time Frame: during the 3 months after tisagenlecleucel administration ]Evaluating the efficacy of tisagenlecleucel therapy from all manufacturing facilities as measured by overall remission rate (ORR) during the 3 months after tisagenlecleucel administration. ORR included complete response (CR) and CR with incomplete blood count recovery (CRi) as determined by an Independent Review Committee ( IRC) assessment.
- Percentage of Patients Who Achieve Best Overall Response (BOR) or CR or CRi With an MRD Negative Bone Marrow by Central Analysis Using qPCR [ Time Frame: 3 months ]
- Percentage of Patients Who Achieve CR or CRi at Month 6 Without SCT Between CTL019 Infusion and Month 6 Response Assessment. [ Time Frame: 6 months ]
- Duration of Remission (DOR) [ Time Frame: 60 months ]
- Percentage of Patients Who Achieve CR or CRi With Minimal Residual Disease Negative Bone Marrow [ Time Frame: 3 months ]
- Relapse-free Survival [ Time Frame: 60 months ]
- Event-free Survival [ Time Frame: 60 months ]
- Overall Survival [ Time Frame: 60 months ]
- Response at Day 28 +/- 4 Days [ Time Frame: 1 month ]
- Impact of Baseline Tumor Burden on Response [ Time Frame: 60 months ]
- Percentage of Patient Who Achieve CR or CRi and Then Proceed to SCT While in Remission Before Month 6 Response Assessment [ Time Frame: 6 months ]
- Quality of Response Using MRD Disease Assessments Before Treatment at Day 28 +/-4 Days After Treatment Using Central Assessments by qPCR and Before SCT by Local Assessment (Flow or PCR) [ Time Frame: 60 months ]
- Safety of CTL019 Therapy [ Time Frame: 60 months ]
- Characterize in Vivo Cellular PK Profile of CTL019 Cells in Target Tissues [ Time Frame: 60 months ]
- Prevalence and Incidence of Immunogenicity to CTL019 [ Time Frame: 60 months ]
- Effects of CTL019 Therapy on Patient Reported Outcomes [ Time Frame: 60 months ]
- Derivation of a Score to Predict Cytokine Release Syndrome [ Time Frame: 3 months ]
- Describe the Profile of Soluable Immune Factors That May be Key to Cytokine Release Syndrome [ Time Frame: 6 months ]
- Describe Levels of B and T Cells (Blood and Bone Marrow) Prior to and Following CTL019 Infusion for Safety Monitoring [ Time Frame: 3 months ]
