Trial of Lu-177 DOTATATE (Lutathera®) in Unlicensed Indications
110 participantsStarted 2023-12-18
Plain-language summary
This study is a phase 2, open, single-site trial. The primary objective of this study is to prospectively evaluate the safety and efficacy in participants treated with Lu-177 DOTATATE (Lutathera) in unresectable or metastatic, somatostatin receptor-expressing neuroendocrine tumours (NET) in currently unlicensed indications (eg, bronchial and thymic NET; paraganglioma/phaeochromocytoma; medullary thyroid carcinoma; and those requiring repeat peptide receptor radionuclide therapy (PRRT) with 2 further cycles of Lutathera). The aim is to recruit a total of 75-110 participants. Each patient will receive 4 cycles of Lutathera with 8-12 weeks time interval (except patients requiring repeat PRRT will receive 2 further cycles of Lutathera). The follow-up period will be for 2 years from the date of the last treatment.

Inclusion criteria
. Patients ≥18 years of age.
. Participants capable of giving informed consent
. Presence of unresectable or metastatic, well differentiated, somatostatin receptor positive non gastroenteropancreatic neuroendocrine tumours. Or for those having 2 cycles repeat therapy, GEP NET \> 18 months from start of previous PRRT.
. Patients must have progressive disease based on RECIST Criteria, Version 1.1. In order to make the assessment, two CT (or MRI) scans are required. The oldest scan must not be older than 3 years from the date of enrolment. The most recent scan must not be older than 6 weeks from the date of enrolment.
. Confirmed presence of somatostatin receptors on all target lesions (for target/non-target/measurable lesions definition see RECIST Criteria, Version 1.1) documented by CT/MRI scans, based on positive OctreoScan or Ga68 Dotatate PET imaging within 24 weeks prior to enrolment in the trial.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
To prospectively evaluate safety in participants treated with Lu-177 DOTATATE (Lutathera) in somatostatin receptor-expressing neuroendocrine tumours (NET) in currently unlicensed indications
Timeframe: 4 years
2
To prospectively evaluate tolerability in participants treated with Lu-177 DOTATATE (Lutathera) in somatostatin receptor-expressing neuroendocrine tumours (NET) in currently unlicensed indications
Timeframe: 4 years
3
To prospectively evaluate efficacy in participants treated with Lu-177 DOTATATE (Lutathera) in somatostatin receptor expressing neuroendocrine tumours (NET) in currently unlicensed indications
. The tumour uptake observed in each target lesion (for target/non-target/measurable lesions definition see RECIST Criteria, Version 1.1) using OctreoScan/Tc-99m-SRS should be ≥ normal liver uptake observed on planar imaging.
. The tumour uptake observed in each target lesion (for target/non-target/ measurable lesions definition see RECIST Criteria, Version 1.1) using Ga68 Dotatate PET should be ≥ normal liver uptake observed on PET imaging.
. KPS ≥60.
Exclusion criteria
. Either serum creatinine \>150 μmol/L (\>1.7 mg/dL), or calculated creatinine clearance \<40 mL/min, eventually confirmed by measured creatinine clearance (or measured GFR using isotopic GFR measurement) \<40 mL/min (the measured creatinine clearance/GFR is required only as confirmatory exam).
