NCT06455358

Brief 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.

Outcome Measures

Primary Outcomes (3)

  • Frequency of adverse events (number)

    The safety of 61Cu-NODAGA-LM3 is assessed in a primary safety analysis that is descriptive in nature and is performed in the safety analysis set, including information about the frequency (number) of adverse events.

    from Baseline up to 18 hours post injection

  • Severity of adverse events assessed by CTCAE 5.0

    The safety of 61Cu-NODAGA-LM3 is assessed in a primary safety analysis that is descriptive in nature and is performed in the safety analysis set, including information about the severity of adverse events. Severity will be graded as per CTCAE (Common Terminology Criteria for Adverse Events) Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting ageappropriate instrumental ADL (Activities of Daily Living). Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL. Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE.

    from Baseline up to 18 hours post injection

  • Assessment of the sensitivity of 61Cu-NODAGA-LM3 PET/CT

    The sensitivity of 61Cu-NODAGA-LM3 PET/CT acquired \~ 1h p.i. is compared with that of the standard of care 68Ga-DOTA-TOC PET/CT acquired \~1h p.i.. Sensitivity is determined based on the adjudication of all suspected lesions (union of the sets of lesions detected by two blinded independent readers) against a gold standard. The gold standard is defined either as a biopsy whenever possible and if clinically indicated or a comparison to the best imaging modality for the patient given case 2 - 7 months during follow up. After all "true" lesions are identified on all images, it is determined whether or not a given lesion has been identified on the 61Cu-NODAGA-LM3 PET/CT and on the 68Ga-DOTA-TOC PET/CT scans.

    1 hour post injection

Secondary Outcomes (13)

  • Positive predictive value of 61Cu-NODAGA-LM3 PET/CT

    1 hour and 3 hours post injection

  • Dosimetry of 61Cu-NODAGA-LM3

    1 hour, 3 and 18 hours post injection

  • Biodistribution of 61Cu-NODAGA-LM3

    1 hour and 3 hours post injection

  • Peak plasma concentration (Cmax) of 61Cu-NODAGA-LM3

    Baseline, 2, 5, 10, 20, and 30 min, 1 hour, 2, 4, and 18 hours post injection

  • Blood clearance of 61Cu-NODAGA-LM3

    Baseline, 2, 5, 10, 20, and 30 min, 1 hour, 2, 4, and 18 hours post injection

  • +8 more secondary outcomes

Other Outcomes (4)

  • Optimal injected activity of 61Cu-NODAGA-LM3

    1 hour and 3 hours post injection

  • Tumor detection rate of 61Cu-NODAGA-LM3 PET/CT

    1 hour and 3 hours post injection

  • Correlation of tumor and organ uptake on 61Cu-NODAGA-LM3 PET/CT and quantitated post-treatment SPECT/CT

    1 hour and 3 hours post injection

  • +1 more other outcomes
