A Study of LY4064809 in Healthy Adult Participants

A Phase 1, Open-Label Study to Assess the Relative Bioavailability of Two LY4064809 Formulations in Healthy Adult Participants

The purpose of this study is to find out how much LY4064809 gets into the blood stream and how long it takes the body to get rid of it when it is given as two formulations. For each participant, the study will last about nine weeks. Participants will remain in the clinical research center for about one month.
