DETECTNET

DistributionAfter 1 to 3 hours of a single dose administration of copper Cu 64 dotatate injection, the maximum radioactivity is observed in adrenal glands, kidney, pituitary glands, spleen, and liver.

Elimination

MetabolismThe metabolism of copper Cu 64 dotatate is unknown.

ExcretionFollowing a single intravenous dose (4.15 ± 0.13 mCi) of Detectnet (n = 6), between 16% to 40% radioactivity of the injected dose was recovered in urine over a 6-hour collection time. Specific Populations The effe...

The efficacy of Detectnet was established in two single-center, open-label studies. Study 1 prospectively evaluated a total of 63 subjects, including 42 patients with known or suspected NET based on histology, conventional imaging, or clinical evaluations and 21 healthy volunteers. Of the 42 patients, 37 (88%) had a history of NETs at the time of Detectnet imaging. Among the total study population of 63 subjects, 28 (44%) were men and 35 (56%) were women with most subjects being white (86%). The mean age of the subjects was 54 years (range 25 to 82 years). Detectnet images from each subject we...

The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity reactions [see Warnings and Precautions ( 5.2 )] Reported adverse reactions include nausea, vomiting, and flushing.

None. None ( 4 ).

Radiation Risk: Ensure safe handling and preparation procedures to protect patients and health care workers from unintentional radiation exposure ( 5.1 ). Advise patients to hydrate before and after administration and to void frequently after administration. ( 2.3 ) Hypersensitivity Reactions: Most reported reactions were rash and pruritus and reversible either spontaneously or with routine symptomatic management. ( 5.2 ) Risk for Image Misinterpretation: Uptake of Detectnet can be seen in a var...

7 DRUG INTERACTIONS Somatostatin Analogs: Somatostatin analogs competitively bind to the same somatostatin receptors as copper Cu 64 dotatate and may affect imaging. Image patients just prior to dosing with somatostatin analogs. For patients on long-acting somatostatin analogs, a wash-out period of 28 days is recommended prior to imaging. For patients on short-acting somatostatin analogs, a washou...
