What this study is testing
The aim of this trial is to determine preliminary activity of the combination treatment with nivolumab and entinostat in children and adolescents with high risk refractory/relapsed/progressive tumors harboring a high mutational load, focal MYC(N) amplification or ATRT-MYC subgroup as well as tumors with high tumor infiltrating lymphocytes (TILs) or a tertiary lymphoid structure (TLS).
