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

Recruiting now · Phase 1/Phase 2

Conditions studied: Neuroendocrine Tumors

In brief

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.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Written informed consent signed
• >18 years old patients of either gender
• For women in child-bearing age: a negative pregnancy test is required
• Histologically proven well-differentiated bronchopulmonary (typical or atypical carcinoid) or gastroenteropancreatic neuroendocrine tumors (NET) of all grade (including NET G3 with Ki-67 <30 %)
• 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
• Standard of care 68Ga-DOTATOC PET/CT performed or planned within max. 4 weeks prior or after IMP-administration, as clinically indicated
• 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
• Estimated eGFR (CKD-EPI) ≥ 45 mL/min
• 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

You may not qualify if…

• Known hypersensitivity to 61Cu, to NODAGA, to LM3 or to any of the excipients of 61Cu-NODAGA-LM3
• 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
• Initiation or continuation of active anti-tumor treatment between 61Cu-NODAGA-LM3 and 68Ga-DOTATOC PET/CT, except continuation of long acting somatostatin analogues
• Presence of active infection at screening or history of serious infection within the previous 6 weeks
• Pregnant or breast-feeding women
• History of somatic or psychiatric disease/condition that may interfere with the objectives and assessments of the study
