61Cu-NODAGA-LM3 PET/CT for the Detection of Neuroendocrine Tumors (COPPER PET in NET)

Neuroendocrine Tumors Clinical Trial

Official title:
61Cu-NODAGA-LM3 PET/CT for the Detection of Neuroendocrine Tumors: The COPPER PET in NET Study A Prospective, Open-label, Randomized, Controlled, Single Centre, Phase I/II PET/CT Study

Clinical Trial Summary

The goal of this monocentric, open-label, randomized-controlled, reader-blind clinical study is to assess the safety of the radiolabeled somatostatin receptor ligand, 61Cu-NODAGA-LM3, and its sensitivity in comparison to the standard of care, 68Ga-DOTATOC, for PET/CT imaging in patients with well differentiated bronchopulmonary and gastroenteropancreatic neuroendocrine tumors.

Clinical Trial Description

Neuroendocrine tumors (NET) originate from neuroendocrine cells and are most commonly found in the gastro-intestinal tract, pancreas and lung. Many NET grow slowly and are asymptomatic, leading to up to 50% being metastatic at diagnosis. Overexpression of somatostatin receptor subtype 2 (SST2) is a characteristic of NET and presents an important molecular target for the management of these tumors. In Switzerland, two radiolabeled somatostatin analogues, gallium-68-labeled (68Ga)-DOTATOC and 68Ga-DOTATATE, are used for SST PET/CT imaging of well-differentiated neuroendocrine tumors. While these radiolabeled SST agonists provide high clinical performance and can be locally produced, they face limitations such as high costs, limited production capacity, short half-life hindering shipment to smaller centers, and high physiological uptake in organs like the liver, complicating tumor detection. A novel copper-61 (61Cu) labeled somatostatin receptor antagonist, 61Cu-NODAGA-LM3, shows promise as an imaging agent for SST2 expressing tumors. It offers a longer half-life, enhanced tumor uptake and retention compared to established radiolabeled SST agonists, and improves image contrast. This study aims to compare the safety and sensitivity of 61Cu-NODAGA-LM3 to the standard of care, 68Ga-DOTATOC, for SST PET/CT imaging in patients with well-differentiated bronchopulmonary and gastroenteropancreatic neuroendocrine tumors. The results of the study potentially lead to enhanced diagnostic accuracy and patient care in the management of neuroendocrine tumors. ;
