Investigating molecular signatures in pediatric chronic myeloid leukemia

CML Pediatric ITK Response According to Molecular Identification at Diagnosis (CML Piramid

Observational University Hospital, Bordeaux · NCT05605379

This study is trying to find out if certain gene changes in children with chronic myeloid leukemia can help predict how well they will respond to a specific type of cancer treatment.

What this trial studies

This observational study aims to identify molecular signatures that predict the response to tyrosine kinase inhibitors (TKIs) in children diagnosed with chronic myeloid leukemia (CML). By analyzing DNA and RNA samples from pediatric patients at diagnosis, the study will explore the mutation status of 64 genes and their association with treatment outcomes. The research will also include a comparative analysis of gene expression profiles between patients who achieve complete cytogenetic response and those who do not. The goal is to enhance understanding of the molecular landscape of pediatric CML and improve treatment strategies.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 18 years or younger diagnosed with chronic phase chronic myeloid leukemia and who have a Philadelphia chromosome.

Not a fit: Patients diagnosed with chronic myeloid leukemia in accelerated or blastic phases, or those over 18 years of age, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized treatment approaches for children with chronic myeloid leukemia, improving their response to therapy.

How similar studies have performed: While there have been limited studies on the molecular status of pediatric CML, this approach of using next-generation sequencing to identify predictive signatures is relatively novel.
