Summary

This trial is testing a new cancer drug combo to see if it's safe and effective. So far it's looking good, with few side effects.

Who is the study for?
This trial is for children with solid tumors, including CNS tumors, that have worsened or not responded to standard treatments. They must be mostly recovered from previous therapies and have a performance status score of ≥40. Participants need measurable disease and agree to use contraception. Exclusions include severe diseases, uncontrolled blood pressure, recent major surgery or bleeding events, certain anticoagulation therapies, prior cabozantinib treatment, inability to swallow tablets, allogeneic stem cell transplant recipients or TBI patients.
What is being tested?
The study tests the safety and appropriate dosing of cabozantinib combined with 13-cis-retinoic acid in pediatric patients whose solid tumors are resistant to standard care. It aims to find the highest dose that can be given without causing serious side effects (maximum tolerated dose) by gradually increasing doses among participants.
What are the potential side effects?
Potential side effects may include toxic reactions affecting various organs due to cabozantinib and 13-cis-retinoic acid combination therapy. Specific risks could involve gastrointestinal issues like perforation or fistula formation; bleeding complications; high blood pressure; bone marrow suppression leading to low blood counts.
