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.
This is a single arm, open-label, multi-center, phase II study to determine the efficacy and safety of CTL019 in pediatric patients with r/r B-cell ALL.
