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.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
LY4064912 (an experimental drug given as an injection under the skin or into a vein)
What this could lead to
If successful, this could lead to a new weight-loss treatment option for people with overweight or obesity.
What could go wrong
This is a very early Phase 1 trial focused on safety, not weight loss. The drug may cause side effects or fail to work in larger studies.
