Is this trial a fit for you?

Likely a good fit

Ideal candidates include pediatric and young adult patients with relapsed or refractory solid tumors or leukemia who are eligible for molecular profiling and potential experimental treatments.

Probably not a fit

Patients with tumors that are not relapsed or refractory to standard treatment 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

MAPPYACTS 2 is an international multicentric clinical initiative aimed at providing tailored therapeutic recommendations based on the molecular characteristics of tumors in pediatric and young adult patients with relapsed or refractory malignancies. The study utilizes advanced genomic techniques, including Whole Exome Sequencing and RNA Sequencing, to identify genomic alterations that may inform targeted treatment options. It also aims to create a comprehensive clinical database to track treatment outcomes and enhance patient care through collaboration among biologists, scientists, and physicians. The program will link to interventional studies and ancillary research to foster the development of new treatment strategies.

Why it matters

Potential benefit: If successful, this approach could lead to more effective and personalized treatment options for children and young adults with difficult-to-treat cancers.

How similar studies have gone: Previous studies utilizing molecular profiling for cancer treatment have shown promise, indicating that this approach is building on established methodologies.
