Lutathera ? : The First FDA- and EMA-Approved Radiopharmaceutical for Peptide Receptor Radionuclide Therapy

摘要

As the first radiopharmaceutical for Peptide Receptor Radionuclide Therapy (PRRT), Lutathera ? was approved by the EMA in 2017 and the FDA in 2018 for the treatment of somatostatin receptor (SSTR) positive gastroenteropancreatic neuroendocrine tumors. Using the concept of PRRT, Lutathera ? combines the radionuclide 177 Lu with the somatostatin analogue DOTA-TATE, thus delivering ionizing radiation specifically to tumor cells expressing somatostatin receptors. As a result, DNA single- and double-strand breaks are provoked, in case of double-strand breaks leading to cell death of the tumor and its SSTR-positive lesions.
