University of Wisconsin, MadisonUsing Novel Imaging to More Safely Treat Neuroendocrine Tumors
Clinical Trial NCT06122610 is designed to study Treatment for Neuroendocrine Tumors, Somatostatin Receptor-positive Neuroendocrine Tumor. It is a Phase 1 interventional trial that is recruiting, having started on March 7, 2025, with plans to enroll 10 participants. Led by University of Wisconsin, Madison, it is expected to complete by February 1, 2026. The latest data from ClinicalTrials.gov was last updated on May 13, 2025.
Brief Summary
The goal of this research is to determine if DetectnetTM PET/CT can be used to make Lutathera therapy safer for patients with neuroendocrine cancer.
Participants will:
- Complete two phases involving 6 visits
- Undergo additional research PET/CT, and possibly SPECT/CT scans
Detailed Description
The goal of this research study is to determine if DetectnetTM PET/CT scanning over several days can be used to deliver Lutathera in a safer manner.
In this research, participants will be asked to complete a screening phase and possibly a dosimetry phase. The screening phase will require 2 visits. The dosimetry phase will also require 3 research visits.

Primary Outcome Measures
Secondary Outcome Measures
| Outcome Measure | Measure Description | Time Frame |
|---|---|---|
Compare pre-therapy and post-therapy voxel-based dosimetry estimates | Absorbed doses to organs will be estimated using radiation dosimetry methods based on both multi-timepoint PET and multi-timepoint SPECT imaging. Mean dose estimates in units of Gy to the index tumor(s) and dose limiting organs (kidneys and bone marrow) will be compared between PET-based dosimetry and SPECT-based dosimetry. Using SPECT-based dosimetry as the gold standard truth, Bland-Altman analysis will be performed for each organ/tumor to compare PET-based dose estimates to SPECT-based estimates. Mean bias and 95% confidence intervals will be calculated. | Baseline and 120 hours post-dose |
| Outcome Measure | Measure Description | Time Frame |
|---|---|---|
Absorbed radiation doses | Absorbed radiation doses from 177Lu-DOTATATE in organs will be summarized with descriptive statistics. | 1 hour post-dose, 4 hours post-dose, 48 hours post-dose, 120 hours post-dose |
Absorbed radiation doses of 64Cu-DOTATATE | Absorbed radiation doses of 177Lu-DOTATATE in organs using 64Cu-DOTATATE as an imagining surrogate will be summarized with descriptive statistics. | 1 hour post-dose, 4 hours post-dose, 48 hours post-dose, 120 hours post-dose |
Compare 3D voxel-based versus model based dosimetry in participants receiving 177Lu_DOTATATE | Absorbed doses to organs will be estimated using radiation dosimetry methods based on multi-timepoint SPECT imaging. Mean dose estimates in units of Gy to the index tumor(s) and dose limiting organs (kidneys and bone marrow) will be compared between 3D voxel-based and model-based dosimetry methods. Using 3D voxel-based dosimetry as the gold standard truth, Bland-Altman analysis will be performed for each organ/tumor to compare 3D voxel-based to model-based methods. Mean bias and 95% confidence intervals will be calculated. | Baseline and 120 hours post-dose |
