NCT01967537 ↗	Evaluation of 68Gallium-DOTATATE PET/CT for Detecting Neuroendocrine Tumors	Completed	National Cancer Institute (NCI)	Phase 2	2013-10-18	Background: - Neuroendocrine tumors (NETs) are rare but have been more common over the past decade. The only treatment for NETs is surgery, but most are found when they are too advanced for surgery. Researchers are looking for the best way to find NETs earlier, so that surgery can be successful. They want to test if the study drug can be used along with imaging devices to detect NETs. Objectives: - To see how well a new experimental imaging agent, 68Gallium-DOTATATE, detects unknown primary and metastatic NETs in the gastrointestinal system and pancreas. Eligibility: - Adults over 10 years old with a suspected NET or family history of NET. Design: - Participants will be screened with a medical history and physical exam, and have a blood test. - Participants will undergo three scans. For all of these, a substance is injected into their body, they lie on a table, and a machine takes images. - A standard computed tomography (CT) scan of the chest, abdomen, and pelvis. - An octreotide scintigraphy Single photon emission computed tomography (SPECT)/CT. - A 68Gallium-DOTATATE positron emission tomography (PET)/CT. The study drug is injected into a vein, usually in the arm. Low-dose X-rays go through the body. For about 40 minutes a large, donut-shaped device takes images of the body. The entire session takes 90 to 120 minutes. - Researchers will compare images from the three scans. - Participants will have 1 follow-up visit each year for 5 years. At this visit, they will have a medical exam, blood taken, and a CT scan.

Gallium Dotatate (Ga-68) Clinical Trials, Market Analysis, and Future Projections

Last updated: February 20, 2026

What is the current status of clinical research on gallium dotatate (Ga-68)?

Gallium dotatate (Ga-68) is used primarily in imaging neuroendocrine tumors (NETs). As of 2023, over 70 clinical trials have evaluated Ga-68's efficacy and safety, with most data confirming high sensitivity and specificity in detecting NETs. The most prominent phase III trial was the NETTER-1 study, completed in 2017, demonstrating Ga-68 dotatate PET/CT's superior diagnostic accuracy over conventional imaging modalities such as SPECT.

Additional ongoing studies explore expanding indications, including imaging of non-NET tumors and evaluating Ga-68's diagnostic performance in early-stage disease, with many trials expected to complete by 2025.

How does Ga-68 perform in clinical diagnostics?

Ga-68 dotatate PET/CT shows detection rates exceeding 90% in well-differentiated NETs, outperforming previous imaging methods:

Parameter	SPECT (In-111)	Ga-68 PET/CT
Sensitivity	~78%	>90%
Specificity	~100%	~95%
Detection of lesions	Fewer false positives	Higher resolution, fewer missed lesions

The improved resolution is attributed to the higher spatial resolution of PET over SPECT. It enables better staging, leading to altered management in approximately 30% of cases in clinical settings, as reported in multiple retrospective analyses.
