Lutathera (lutetium Lu 177 dotatate), a Lu-177-labeled somatostatin analogue, is a radioactive drug used to treat somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

How It Works:

  • Lutathera is a Lu-177-labeled somatostatin analogue, meaning it binds to somatostatin receptors found on GEP-NET cells.
  • Once attached, the radioactive component (Lu-177) delivers targeted radiation to the tumor, helping to kill cancer cells while minimizing damage to surrounding healthy tissue.

FDA Approval:

Lutathera was FDA-approved in January 2018 for the treatment of GEP-NETs, a rare group of cancers that develop in the:

  • Pancreas
  • Stomach
  • Intestines
  • Colon
  • Rectum

It is currently approved for people ages 12 years and older.
