Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Effect of continued LA-SSA use on the absorbed dose in tumor lesions during PRRT. | SPECT/CT after 4h, 24h, and 5-7 days post-injection | |
| Secondary | Effect of continued LA-SSA use on the absorbed dose in normal tissues during PRRT. | SPECT/CT after 4h, 24h, and 5-7 days post-injection and blood samples at 2h, 4h, 24h and 5-7 days post-injection | |
| Secondary | Effect of continued LA-SSA use on the tumor-to-background ratio. | SPECT/CT after 4h, 24h, and 5-7 days post-injection | |
