Could a diabetes drug boost rectal cancer treatment?
NCT ID NCT07314528
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a weight-loss medication (a GLP-1 drug) to standard chemo-radiation before surgery helps rectal cancer patients with a high BMI. About 42 participants will either get the drug plus standard treatment or standard treatment alone. Researchers will measure weight loss, tumor response, and survival to see if the drug improves outcomes.
