This trial is for children and young people with high-risk neuroblastoma, a type of cancer. The study tests treatments to see if adding iobenguane I-131 or lorlatinib to standard therapy can improve survival rates. Iobenguane I-131 is a radioactive drug that targets cancer cells, while lorlatinib blocks enzymes that help cancer cells grow.
