Explore how the 12.7-hour half-life of 64Cu supports flexible scheduling and the advantages of cyclotron production.
Dosing & Administration
Ready-made doses allow for quick and simple preparation3
Detectnet is supplied in single-dose vials.3
In adults, the recommended dose of Detectnet is 4 mCi (148 MBq), providing an effective radiation dose of 4.7 mSv.3
Detectnet should be administered as an intravenous injection over 1 minute, adhering to appropriate radiation safety measures.3 All vials of Detectnet will contain an activity of 4 mCi at 1700 CST with an expiration of 1900 CST.3 Therefore, there is enough drug activity in the vial at day of administration from the earliest morning appointment until the end of the work day.

Q&A
How does production of copper Cu 64 dotatate differ from Gallium Ga 68 dotatate?
Unlike Gallium Ga 68 dotatate, copper Cu 64 dotatate uses daily centralized production and distribution, and is not dependent on a generator schedule.1,5
Are there differences in how copper Cu 64 dotatate and Gallium Ga 68 dotatate are prepared?
With copper Cu 64 dotatate, there is no kit preparation required,3 which helps simplify workflows and support efficient patient throughput.3,5,6
How does the half-life of copper Cu 64 dotatate compare with Gallium Ga 68 dotatate in supporting practice workflows?
The 12.7‑hour half-life of copper Cu 64 dotatate helps maintain dose viability over a wider dosing and imaging window, minimizing time-sensitive workflow disruptions.1,2

IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Radiation Risk:
Diagnostic radiopharmaceuticals, including Detectnet, contribute to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk of cancer. Ensure safe handling and preparation procedures to protect patients and health care workers from unintentional radiation exposure. Advise patients to hydrate before and after administration and to void frequently after administration.
Hypersensitivity Reactions:
Hypersensitivity reactions following administration of somatostatin receptor imaging agents predominantly consisted of cutaneous reactions such as rash and pruritus. Reactions reversed either spontaneously or with routine symptomatic management. Less frequently hypersensitivity reactions included angioedema or cases with features of anaphylaxis.
Risk for Image Misinterpretation:
The uptake of copper Cu 64 dotatate reflects the level of somatostatin receptor density in NETs, however, uptake can also be seen in a variety of other tumors that also express somatostatin receptors. Increased uptake might also be seen in other non-cancerous pathologic conditions that express somatostatin receptors including thyroid disease or in subacute inflammation, or might occur as a normal physiologic variant (e.g., uncinate process of the pancreas).
A negative scan after the administration of Detectnet in patients who do not have a history of NET disease does not rule out disease.
ADVERSE REACTIONS
In clinical trials, adverse reactions occurred at a rate of < 2% and included nausea, vomiting and flushing. In published trials nausea immediately after injection was observed.
DRUG INTERACTIONS
Somatostatin Analogs:
Non-radioactive somatostatin analogs and copper Cu 64 dotatate competitively bind to somatostatin receptors (SSTR2). Image patients just prior to dosing with somatostatin analogs. For patients on long-acting somatostatin analogs, a washout period of 28 days is recommended prior to imaging. For patients on short-acting somatostatin analogs, a washout period of 2 days is recommended prior to imaging.
USE IN SPECIFIC POPULATIONS
Pregnancy:
All radiopharmaceuticals, including Detectnet have the potential to cause fetal harm depending on the fetal stage of development and the magnitude of the radiation dose. Advise a pregnant woman of the potential risks of fetal exposure to radiation from administration of Detectnet.
Lactation:
Advise a lactating woman to interrupt breastfeeding for 12 hours after Detectnet administration in order to minimize radiation exposure to a breastfed infant.
Pediatric Use:
The safety and effectiveness of Detectnet have not been established in pediatric patients.
Geriatric Use:
In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
OVERDOSAGE
In the event of a radiation overdose, the absorbed dose to the patient should be reduced where possible by increasing the elimination of the radionuclide from the body by reinforced hydration and frequent bladder voiding. A diuretic might also be considered.
INDICATIONS AND USAGE
Detectnet is indicated for use with positron emission tomography (PET) for localization of somatostatin receptor positive neuroendocrine tumors (NETs) in adult patients.
