A Study of LY3549492 in Healthy Participants

Study Overview
=================
Brief Summary
-----------------
The main purpose of this study is to evaluate the safety and tolerability of LY3549492 in healthy participants. The blood tests will be performed to check how much LY3549492 gets into the bloodstream and how the body handles LY3549492. This study includes two parts and will last up to approximately 76 days for each participant, including screening.
