Copper (64Cu) oxodotreotide, sold under the brand name Detectnet, is a radioactive diagnostic agent used in positron emission tomography (PET) of neuroendocrine tumors (NETs).[1] Specifically it is used in adults with somatostatin receptor positive disease.[1] It is given by injection into a vein.[1]

Common side effects include nausea, vomiting, and flushing.[1] Other side effects include radiation exposure and allergic reactions.[1] It interacts with somatostatin analogs.[1] Use during pregnancy may harm the baby.[1] It works by binding to somatostatin receptor, particularly subtype 2 receptors.[1]

Copper (64Cu) oxodotreotide was approved for medical use in the United States in 2020.[1] In the United States it costs about 3,900 USD for a vial as of 2022.[2]

Medical uses


It is typically used at a dose of 148 MBq (4 mCi).[1]


The U.S. Food and Drug Administration (FDA) approved copper 64Cu dotatate based on data from two trials that evaluated 175 adults.[3]

Trial 1 evaluated adults, some of whom had known or suspected NETs and some of whom were healthy volunteers.[3] The trial was conducted at one site in the United States (Houston, TX).[3] Both groups received copper 64Cu dotatate and underwent PET scan imaging.[3]

Trial 2 data came from the literature-reported trial of 112 adults, all of whom had history of NETs and underwent PET scan imaging with copper 64Cu dotatate.[3] The trial was conducted at one site in Denmark.[3] In both trials, copper 64Cu dotatate images were compared to either biopsy results or other images taken by different techniques to detect the sites of a tumor.[3] The images were read as either positive or negative for presence of NETs by three independent image readers who did not know participant clinical information.[3]
