The purpose of this study is to test the safety and efficacy of the investigational drug called Selpercatinib in children whose cancers have a specific genetic change (RET-fusion or RET-mutation). Selpercatinib has been FDA-approved for adults and pediatric patients 12 years of age or older for certain types of lung and thyroid cancers. Selpercatinib is administered in capsule form, liquid suspension, or may also be administered by a feeding tube for subjects who are unable to swallow.
The purpose of this study is to test the safety and efficacy of the investigational drug called repotrectinib in children whose cancers have specific genetic changes (in the ALK, ROS1, or NTRK1-3 genes). This is the first study using this drug in children under 12 years of age. Repotrectinib is administered in capsule form or liquid suspension.
The purpose of the Phase 2 portion of this study is to evaluate the safety and efficacy of the study drug called palbociclib when given in combination with two other drugs (temozolomide and irinotecan) in patients with Ewing sarcoma and when given in combination with topotecan and cyclophosphamide in patients with neuroblastoma.
This study involves taking a study drug called Lutathera. The overall goal of this study is to see if Lutathera is safe in adolescent subjects with either a gastroenteropancreatic neuroendocrine tumor (GEP-NET), or a pheochromocytoma and/or paraganglioma (PPGL). This study will also look at the levels of radioactivity after Lutathera administration.
