Run by Rennes University Hospital · NCT06649253 · Data updated 2026-11-12

This study looks at how the CD9 gene might affect relapses in children with B-acute lymphoblastic leukemia to help find better ways to diagnose and treat the disease.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are children under 18 years old with a confirmed diagnosis of B-ALL.

Probably not a fit

Patients with isolated extramedullary involvement or those under legal protection may not benefit from this study.

What this trial studies

This project focuses on B-acute lymphoblastic leukaemia (B-ALL), the most common cancer in children, particularly examining the role of the CD9 gene in patient relapses. The study involves collecting bone and blood samples from newly diagnosed patients at three critical points during their treatment. Researchers aim to understand how non-coding RNAs regulate CD9 expression, which may serve as a marker for potential relapses. If successful, this could lead to new diagnostic and therapeutic strategies for managing B-ALL.

Why it matters

Potential benefit: If successful, this study could provide new diagnostic and prognostic markers for predicting relapses in pediatric B-ALL patients.

How similar studies have gone: While the specific approach of targeting CD9 regulation in B-ALL is novel, similar studies have shown promise in understanding gene regulation in cancer.
