NCT ID NCT07152002
First seen Jun 25, 2026 · Last updated Sep 15, 2026 · Updated 5 times
Summary
This early-stage study is testing an experimental drug called LY4064912 in 144 healthy volunteers and people with overweight or obesity. The main goal is to check safety and how the body handles the drug, not yet to prove it works for weight loss. Participants will receive either the drug or a placebo by injection or IV infusion, and researchers will monitor side effects and measure drug levels in the blood.
