Depreotide is an ingredient in the diagnostic aid (radioactive imaging agent). Technetium Tc 99m labeled depreotide is a scintigraphic imaging agent that identifies somatostatin receptor-bearing pulmonary masses in patients presenting with pulmonary lesions on computed tomography and/or chest x-ray who have known malignancy or who are highly suspect for malignancy. Adverse events were evaluated in clinical studies of 647 adults. Deaths did not occur during the clinical study period. After Technetium Tc 99m Depreotide Injection, serious adverse events were not reported. Headache was the most commonly reported adverse event. EMA withdrew depreotide containing agent NeoSpect.
