NCT ID NCT07592546
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 4 trial will study 240 adults aged 35-55 with class I/II obesity to see if weight loss from semaglutide (Ozempic/Wegovy) improves brain health. Participants will take the drug weekly for 80 weeks and undergo MRI scans, cognitive tests, and blood work. The study also includes a lean control group for comparison. The goal is to understand how excess body fat affects the brain and whether weight loss can reverse any abnormalities.
