Awards & highlights


This trial will compare the effects of a new cancer treatment to the best existing cancer treatment.

Who is the study for?
This trial is for adults with aggressive, well-differentiated GEP-NETs that can't be surgically removed and have shown up on scans. Participants must have tumors with somatostatin receptors but cannot join if they're pregnant, breastfeeding, hypersensitive to the drugs being tested, recently had major surgery or other cancer treatments, or have serious health issues affecting their organs.Check my eligibility
What is being tested?
The COMPOSE study is testing whether a treatment called 177Lu-Edotreotide (a type of PRRT) works better as a first or second option compared to standard therapies like CAPTEM, Everolimus, FOLFOX for certain neuroendocrine tumors. Patients will either receive this new therapy or one of the established treatments.See study design
What are the potential side effects?
Possible side effects include reactions related to radiation exposure from PRRT such as nausea and fatigue; kidney damage; blood cell count changes leading to increased infection risk; liver toxicity; and allergic reactions to any component of the treatment.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
The most common treatments for Neuroendocrine Tumors (NETs) include peptide receptor radionuclide therapy (PRRT) with agents like 177Lu-Edotreotide and 177Lu-Dotatate, and systemic therapies such as everolimus. PRRT targets somatostatin receptors on tumor cells to deliver targeted radiation, effectively killing cancer cells while minimizing damage to healthy tissue. Everolimus is an mTOR inhibitor that interferes with cancer cell growth and proliferation. These mechanisms are important for NET patients as they guide the selection of treatment based on the tumor's receptor status and the patient's overall health, aiming to maximize efficacy and minimize side effects.
