NCT ID NCT05460533

First seen Nov 01, 2025 · Last updated May 01, 2026 · Updated 26 times

Summary

This study tests whether giving a second, early infusion of the CAR T-cell therapy tisagenlecleucel can keep the immune system's B cells suppressed for at least 6 months in children and young adults with relapsed or hard-to-treat B-cell acute lymphoblastic leukemia. About 30 participants who already received one dose and have extra cells available will get an early reinfusion. The goal is to reduce the rate of losing B-cell aplasia from 26% to below 10%, which may help prevent the cancer from coming back.
