Definition

A radioactive drug used to treat adults and children aged 12 years and older with gastroenteropancreatic neuroendocrine tumors that are somatostatin receptor positive. It is also being studied in the treatment of other types of cancer. Lutathera binds to a protein called somatostatin receptor, which is found on some neuroendocrine tumor cells. Lutathera builds up in these cells and gives off radiation that may kill them. It is a type of radioconjugate and a type of somatostatin analog. Also called lutetium Lu 177-dotatate.
