Overview

lutetium Lu 177 dotatate + sunitinib malate is a combination therapy being investigated for the treatment of metastatic or unresectable pancreatic neuroendocrine tumors (pNETs). The combination pairs **lutetium Lu 177 dotatate** (Lutathera), a peptide receptor radionuclide therapy (PRRT), with **sunitinib malate** (Sutent), a multi-targeted receptor tyrosine kinase inhibitor. Lutetium Lu 177 dotatate consists of a somatostatin analogue (dotatate) linked to the beta-emitting radioisotope lutetium-177, which targets and destroys cells expressing somatostatin receptor type 2 (SSTR2). Sunitinib malate complements this by inhibiting several kinases involved in tumor growth and angiogenesis, including vascular endothelial growth factor receptors (VEGFR) and platelet-derived growth factor receptors (PDGFR). This combination is currently being evaluated in a Phase I trial (NCT05687123) sponsored by the National Cancer Institute (NCI) to determine safety and potential synergistic effects in patients with somatostatin receptor-positive pNETs.
