Long-lasting radionuclide therapy for advanced neuroendocrine tumors proves effective

Shawn Chen | Via EurekAlert | June 25, 2018

A first-in-human study presented at the 2018 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) demonstrates the benefits and safety of a new, long-lasting type of radionuclide therapy for patients with advanced, metastatic neuroendocrine tumors (NETs).

Lutathera-177 (177Lu)-DOTATATE (trade name Lutathera), a peptide receptor radionuclide tharapy (PRRT) with radiolabeled somatostatin analogues (peptides), was recently approved by the U.S. Food and Drug Administration for the treatment of NETs. It is the therapeutic part of a nuclear medicine theranostic pairing. Gallium-68 (68Ga)-DOTATATE is the diagnostic agent used in positron emission tomography/computed tomography (PET/CT) scans that first locates and marks the lesions for follow-up with targeted PRRT delivery directly to the tumor cells which express high levels of somatostatin receptors (SSTRs). Because the PRRT binds to receptors expressed by the tumor cells, healthy cells are unharmed… Continue reading.
