About This Study

This phase II trial compares the effect of retreatment with 177Lu-DOTATATE peptide receptor radionuclide therapy (PRRT) to the usual approach of treatment with everolimus, sunitinib, or cabozantinib in patients who have previously received 177Lu-DOTATATE for gastroenteropancreatic neuroendocrine tumor (GEPNET) that has spread from where it first started (primary site) to other places in the body (metastatic) and that cannot be removed by surgery (unresectable).

Who Can Participate

Inclusion Criteria

Patients must be at least \>= 18 years of age
Metastatic, histologically confirmed grade 1 or 2 well-differentiated gastroenteropancreatic neuroendocrine tumours, including NETs of unknown primary thought to be of gastroenterogancreatic origin, with positive Gallium-68 DOTATATE scan, Copper-64 DOTATATE scan or octreotide scan within the last 12 months is recommended but within the last 36 months is allowed. Lesions on Gallium-68 or Copper-64 DOTATATE scan or octreotide scan will be considered positive if the maximum standardized uptake value (SUVmax) of target lesion is \> SUV mean of normal liver parenchyma
7th Edition of the TNM Classification of Malignant Tumours
Have received 3 or 4 cycles of PRRT using 177Lu-DOTATATE or a cumulative exposure of 22,200 MBq (600mCi) or 29,600 MBq (800 mCi) within +/- 10% variation within a 52-week period. No previous targeted alpha therapy is permitted
Have had radiological progression per RECIST 1.1 after prior PRR

Frequently Asked Questions

Q:What is a clinical trial?

A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.

Q:Is it safe to participate?

Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.

Q:Will I be compensated?

Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.

Q:Will I receive a placebo instead of treatment?

When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.

Q:Can I leave a trial if I change my mind?

Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.

Q:How long does a clinical trial last?

Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
