Summary

This study was designed to test two immunotherapy drugs, nivolumab and ipilimumab, in children and young adults with cancers that returned or didn't respond to treatment and had many genetic mutations. The goal was to see if the drug combination was safe and could shrink tumors. However, the trial was withdrawn before enrolling any participants, so no results are available.
