Lutathera in Somatostatin Neuroendocrine Tumors
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.
