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.\n\nIn 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.\n\nA 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.\n\nThis 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.\n\nThe results of the study potentially lead to enhanced diagnostic accuracy and patient care in the management of neuroendocrine tumors.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Written informed consent signed\n* \\>18 years old patients of either gender\n* For women in child-bearing age: a negative pregnancy test is required\n* Histologically proven well-differentiated bronchopulmonary (typical or atypical carcinoid) or gastroenteropancreatic neuroendocrine tumors (NET) of all grade (including NET G3 with Ki-67 \\<30 %)\n* Clinical indication to somatostatin receptor (SST) PET/CT imaging for either primary staging, restaging, patient selection to Peptide Receptor Radionuclide Therapy, treatment planning or treatment response assessment\n* Standard of care 68Ga-DOTATOC PET/CT performed or planned within max. 4 weeks prior or after IMP-administration, as clinically indicated\n* At least 3 lesions detected by the previous somatostatin receptor scan, or if 68Ga-DOTATOC PET/CT is negative, a positive NETest not older than 4 weeks should be available in 5 additional patients\n* Estimated eGFR (CKD-EPI) ≥ 45 mL/min\n* If applicable, the last regular somatostatin analogue injection should be administered 2 weeks +/- 1 week prior to SST PET scan for long acting release forms\n\nExclusion Criteria:\n\n* Known hypersensitivity to 61Cu, to NODAGA, to LM3 or to any of the excipients of 61Cu-NODAGA-LM3\n* Prior or planned administration of a radiopharmaceutical within 8 half-lives of the radionuclide used on such radiopharmaceutical including at any time during the current study\n* Initiation or continuation of active anti-tumor treatment between 61Cu-NODAGA-LM3 and 68Ga-DOTATOC PET/CT, except continuation of long acting somatostatin analogues\n* Presence of active infection at screening or history of serious infection within the previous 6 weeks\n* Pregnant or breast-feeding women\n* History of somatic or psychiatric disease/condition that may interfere with the objectives and assessments of the study'}, 'identificationModule': {'nctId': 'NCT06455358', 'briefTitle': '61Cu-NODAGA-LM3 PET/CT for the Detection of Neuroendocrine Tumors (COPPER PET in NET)', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital, Basel, Switzerland'}, 'officialTitle': '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', 'orgStudyIdInfo': {'id': '2023-01981;
