Gallium edotreotide Ga-68 is a radioconjugate consisting of the octreotide derivative edotreotide labeled with gallium 68 (Ga-68). Similar to octreotide, gallium Ga 68-edotreotide binds to somatostatin receptors (SSTRs), especially type 2 receptors, present on the cell membranes of many types of neuroendocrine tumor cells and their metastases, thereby allowing for imaging of SSTR-expressing cells with positron emission tomography (PET). Gallium edotreotide Ga-68 has been authorized in the EU as SomaKit for the diagnosis of gastro-entero-pancreatic neuroendocrine tumors. It was investigated in clinical trials for imaging of brain tumors, pituitary tumors and neuroendocrine tumors of various origin.
