Testing Lutetium Lu 177 Dotatate in Patients With Somatostatin Receptor Positive Advanced Bronchial Neuroendocrine Tumors

What this study is about

This phase II trial studies the effect of lutetium Lu 177 dotatate compared to the usual treatment (everolimus) in treating patients with somatostatin receptor positive bronchial neuroendocrine tumors that have spread to other places in the body (advanced). Lutetium Lu 177-dotate is a radioactive drug.

View original scientific description

This phase II trial studies the effect of lutetium Lu 177 dotatate compared to the usual treatment (everolimus) in treating patients with somatostatin receptor positive bronchial neuroendocrine tumors that have spread to other places in the body (advanced). Lutetium Lu 177-dotate is a radioactive drug. It binds to a protein called somatostatin receptor, which is found on some neuroendocrine tumor cells. Lutetium Lu 177-dotatate builds up in these cells and gives off radiation that may kill them.

Primary outcome measures

Median progression-free survival (PFS)

Time frame: From randomization until either radiographic progression confirmed by central radiology review or death, assessed up to 5 years from study registration

Will be compared between patients with a bronchial neuroendocrine tumor receiving lutetium Lu 177 dotatate to those receiving everolimus. The distribution of PFS will be estimated using the Kaplan Meier method. Will be tested using a one-sided stratified log rank test. The median PFS, along with 90% confidence intervals (CIs), will be estimated for the two treatment groups.

Who can participate

This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

Non-measurable disease includes disease smaller than these dimensions or lesions considered truly non-measurable including: leptomeningeal disease, bone metastases, ascites, pleural or pericardial effusion, lymphangitic involvement of skin or lung
  • REGISTRATION: Confirmation of SSTR positivity by Alliance Imaging Core Lab (ICL) at Imaging and Radiation Oncology Core (IROC) Ohio central radiographic review

Frequently asked questions

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.

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.

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.

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.

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.

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.
