CD19 targeted CAR T cell therapy for children with relapsed or refractory B cell leukemia and lymphoma

Official title: A Single-Arm, Open-Label, Multicenter, Phase 1b/2 Study Evaluating the Safety and Efficacy of AUTO1 (Obecabtagene Autoleucel [Obe-cel]) in Pediatric Patients With CD19-positive Relapsed/Refractory (R/R) B Cell Acute Lymphoblastic Leukemia (B ALL) or R/R Aggressive Mature B Cell Non-Hodgkin Lymphoma (B NHL).

Run by Autolus Limited · NCT06173518 · Data updated 2026-11-12

This study is testing a new CAR T cell therapy for children with tough-to-treat B cell leukemia and lymphoma to see if it can help them feel better.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are pediatric patients under 18 years old with relapsed or refractory CD19-positive B ALL or B NHL.

Probably not a fit

Patients with non-CD19-positive malignancies or those who do not meet the age and weight criteria may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase Ib study evaluates the safety and preliminary efficacy of autologous T cells engineered with a chimeric antigen receptor (CAR) targeting CD19 in pediatric patients with relapsed or refractory B cell acute lymphoblastic leukemia (B ALL) and aggressive mature B-cell non-Hodgkin lymphoma (B NHL). The study is single-arm and open-label, involving sequential periods of screening, leukapheresis, lymphodepletion, treatment evaluation, and follow-up. Safety data will be monitored continuously, with an Independent Data Monitoring Committee reviewing the data after specific patient milestones.

Why it matters

Potential benefit: If successful, this therapy could provide a new treatment option for children with difficult-to-treat B cell malignancies.

How similar studies have gone: Other studies using CAR T cell therapy targeting CD19 have shown promising results, indicating potential for success in this approach.
