Understanding why CAR T cells don't last in leukemia treatment
Official title: Determining the Mechanisms of Loss of CAR T Cell Persistence
Run by University College, London · NCT05809284 · Data updated 2026-11-12
This study looks at kids and young adults with leukemia to see why CAR T cells don't stick around long enough after treatment and what might help them last longer.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are children and young adults aged 25 years or younger with relapsed or refractory acute lymphoblastic leukemia who are scheduled to receive CAR T-cell treatment.
✕Probably not a fit
Patients receiving an alternate CD19-directed CAR T-cell product on a clinical trial 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 observational study focuses on pediatric and young adult patients with acute lymphoblastic leukemia (ALL) who are set to receive CD19-targeted CAR T-cell therapy. It aims to investigate the persistence of CAR T cells over time and identify the factors that may influence their longevity. By monitoring these patients, researchers hope to gather valuable data that can inform future treatments and improve outcomes for ALL patients.
Why it matters
Potential benefit: If successful, this study could lead to improved CAR T cell therapies that enhance treatment effectiveness for leukemia patients.
How similar studies have gone: While this study explores a specific aspect of CAR T cell therapy, similar studies have shown promise in understanding CAR T cell dynamics and improving treatment outcomes.
