Can a new injectable drug pass its first human safety test?
NCT ID NCT07767487
First seen Aug 17, 2026 · Last updated Aug 18, 2026 · Updated 1 time
Summary
This early-stage trial is testing an experimental drug called LY4226695 in healthy volunteers to see how safe it is and what side effects it might cause. Participants receive either the drug or a placebo, given as an injection under the skin or into a vein. The study also measures how the body absorbs, processes, and eliminates the drug. Results will help determine whether further testing in patients is warranted.

- If successful, this early study could pave the way for further testing of LY4226695 as a potential treatment for future conditions.
- What could go wrong
- This is a very early Phase 1 trial in a small number of healthy people, so it is primarily about safety and dosing. The drug may cause side effects, and its effectiveness for any disease is unknown.
