Summary

This is a single arm, open-label, multi-center, phase II study to determine the efficacy and safety of tisagenlecleucel in de novo HR pediatric and young adult B-ALL patients who received first-line treatment and are EOC MRD positive. The study will have the following sequential phases: screening, pre-treatment, treatment \& follow-up, and survival. After tisagenlecleucel infusion, patient will have assessments performed more frequently in the first month and then at Day 29, then every 3 months for the first year, every 6 months for the second year, then yearly until the end of the study. Efficacy and safety will be assessed at study visits and as clinically indicated throughout the study.

A post-study long term follow-up safety will continue under a separate protocol per health authority guidelines.
