Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multi-center, phase Ib/II trial to evaluate the safety and efficacy of CNCT19 treatment in Children and Adolescent (pediatric) patients with relapsed or refractory B-cell acute lymphoblastic leukemia (r/r B-cell ALL).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This trial is a multi-center, open label, single-arm, phase Ib/II trial to evaluate the safety and efficacy of CNCT19 in Children and Adolescent(aged 3\~18 years old) patients (pediatric) with r/r B-cell ALL.

The phase Ib part of the trial is to evaluate the safety, optimal dose of CNCT19, Pharmacokinetics/Pharmacodynamics(PK/PD)and preliminary efficacy in the treatment of Children and Adolescent patients with r/r B-cell ALL.

The phase II part of the trial is to evaluate the efficacy and safety of CNCT19 in in the treatment of Children and Adolescent patients with r/r B-cell ALL.

The study includes screening, pre-treatment (Cell Product manufacture \& lymphodepletion), CNCT19 infusion , safety and efficacy follow-up, and survival follow-up. All subjects who have received CNCT19 infusion will be followed for up to 2 years.
