Study Summary
This trial is testing the side effects and best dose of triapine when given with lutetium Lu 177 dotatate for neuroendocrine tumors. Triapine may stop tumor growth by blocking enzymes needed for cell growth. Lutetium Lu 177 dotatate is a radioactive drug that carries radiation directly to tumor cells. Giving triapine and lutetium Lu 177 dotatate together may be a good way to treat neuroendocrine tumors.
Who is the study for?
Adults with well-differentiated neuroendocrine tumors and positive dotatate scans who have failed at least one cancer treatment. They must show disease progression, have measurable disease, be in good physical condition (ECOG 0-2), and meet specific blood criteria. Excluded are those under 18, pregnant or breastfeeding women, recent major surgery patients, individuals unable to absorb oral meds properly, anyone with uncontrolled heart failure or other serious illnesses.Check my eligibility
What is being tested?
The trial is testing the combination of Triapine and Lutetium Lu 177 Dotatate for treating neuroendocrine tumors. Triapine blocks enzymes needed for tumor growth while Lutetium Lu 177 Dotatate delivers radiation directly to tumor cells. The study aims to find the best dose and assess side effects.See study design
What are the potential side effects?
Potential side effects include reactions related to blocking cell growth enzymes by Triapine and radiation exposure from Lutetium Lu 177 Dotatate which may affect normal cells despite its targeted approach. Specific side effects will be monitored as part of determining the safest effective dose.

Experimental Treatment
Group I: Treatment (lutetium Lu 177 dotatate, triapine)Experimental Treatment5 Interventions
Patients receive lutetium Lu 177 dotatate IV for 30 to 40 minutes on day 1 of each cycle and triapine PO on days 1 throughout 14 of each cycle. Cycles repeat every 56 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan or MRI scan throughout the trial. Patients undergo blood specimen collection on study.
