The main purpose of this study is to assess two formulations of LY3819469 based on the amount that gets into the blood stream and how long it takes the body to get rid of it, when given to healthy participants. The information about any adverse effects experienced will be collected and the tolerability of LY3819469 will also be evaluated.

Screening is required within 28 days prior to the enrolment. For each participant, the total duration of the clinical trial will be about 17 weeks including screening and follow-up periods.
