Is this trial a fit for you?
✓Likely a good fit
Healthy adults aged adult (based on BMI 18.5–35 kg/m2) who meet sex-specific contraception and non-childbearing criteria and, for Parts B and C, fulfill the regional grandparent ancestry requirements.
✕Probably not a fit
Some participants may not experience direct benefits from LY4226695, and all participants may discontinue due to adverse effects or unrelated withdrawal.

What this trial studies
This early-phase interventional trial examines the safety, tolerability, and pharmacokinetics of LY4226695 compared with placebo in healthy participants. The study includes multiple parts with short stays in a Clinical Research Unit to monitor effects and collect blood samples over about 64 to 92 days. Participants undergo periodic inpatient visits to assess how the drug behaves in the body and what side effects may occur. Parts B and C include specific geographic eligibility for Chinese and Japanese cohorts, respectively.
Why it matters
Potential benefit: If successful, the trial could help determine safe dosing and characterize how LY4226695 acts in the body in healthy adults.
How similar studies have gone: Prior early-phase studies in healthy volunteers have provided safety and pharmacokinetic data for similar compounds, but the exact LY4226695 findings will be determined in this trial.
