|Official Title:||A Phase 1/2 Multi-Center Study Evaluating the Safety and Efficacy of KTE-X19 in Pediatric and Adolescent Subjects With Relapsed/Refractory B-precursor Acute Lymphoblastic Leukemia or Relapsed/Refractory B-Cell Non-Hodgkin Lymphoma (ZUMA-4)|
|Actual Study Start Date :||February 1, 2016|
|Estimated Primary Completion Date :||August 2023|
|Estimated Study Completion Date :||August 2038|
Experimental: Single Arm
A conditioning chemotherapy regimen of fludarabine and cyclophosphamide will be administered followed by a single infusion of CAR transduced autologous T cells administered intravenously at a target dose of 2 x 10^6 anti-CD19 CAR+ T cells/kg or 1 x 10^6 anti-CD19 CAR+ T cells/kg
- Phase 1: Percentage of Participants Experiencing Adverse Events Defined as Dose-Limiting Toxicities (DLT) [ Time Frame: Up to 28 days ]Dose-limiting toxicity is defined as protocol-defined KTE-X19-related events with onset within the first 28 days following KTE-X19 infusion.
- Phase 2: Overall Complete Remission Rate in the ALL Cohort [ Time Frame: Up to 24 months ]Overall complete remission rate will be determined per independent review.
- Phase 2: Objective Response Rate in the NHL Cohorts [ Time Frame: Up to 24 months ]Objective Response Rate will be determined per investigator review.
- Minimum Residual Disease Negative Remission Rate in the ALL Cohort [ Time Frame: Up to 3 months ]Minimal residual disease (MRD) response rate is defined as MRD < 10^-4 per the standard assessment.
- Allogeneic Stem Cell Transplant Rate in the ALL Cohort [ Time Frame: Up to 24 months ]The incidence of allogeneic stem cell transplant will be analyzed.
- Changes Over Time in PRO Scores in the ALL Cohort [ Time Frame: Up to 15 years ]
- Overall Complete Remission Rate in the ALL Cohort [ Time Frame: Up to 15 years ]
- Relapse-Free Survival for the ALL Cohort [ Time Frame: Up to 24 months ]Relapse-Free Survival is defined as the time from the KTE-X19 infusion date to the date of disease relapse or death from any cause.
- Progression Free Survival in the NHL Cohort [ Time Frame: Up to 15 years ]
- Overall Survival in the ALL and NHL Cohorts [ Time Frame: Up to 15 years ]Overall survival is defined as the time from KTE-X19 infusion to the date of death from any cause.
- Duration of Remission in the ALL and NHL Cohorts [ Time Frame: Up to 24 months ]Duration of remission is defined as the time between the participant's first complete response per independent review to relapse or any death in the absence of documented relapse.
- Percentage of Participants with Anti-KTE-X19 Antibodies in Blood in the ALL and NHL Cohorts [ Time Frame: Up to 15 years ]
- Percentage of Participants Experiencing Adverse Events and Common Terminology Criteria for Adverse Events (CTCAE) Grade Changes in Safety Laboratory Values in ALL and NHL Cohorts [ Time Frame: Up to 15 years ]
