Study Description

Brief Summary

The main purpose of this study is to evaluate the safety and tolerability of the study drug known as LY3540378 in healthy participants following single and multiple doses (Parts A and

  1. and multiple doses in Japanese (Part C) and Chinese (Part D) healthy participants. Blood tests will be performed to check how much LY3540378 gets into the bloodstream and how long it takes the body to eliminate it. This is a 4-part study and may last up to 70, 113, 113 and 113 days for each participant in Parts A, B, C, and D respectively.

Outcome Measures

Primary Outcome Measures

  1. Number of Participants with One or More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration [Baseline up to Day 113]

    A summary of SAEs and other non-serious adverse events (AEs), regardless of causality, will be reported in the Reported Adverse Events module

Secondary Outcome Measures

  1. Pharmacokinetics (PK): Maximum Concentration (Cmax) of LY3540378 [Predose on Day 1 through Day 113]

    PK: Cmax of LY3540378

  2. PK: Area Under the Concentration Versus Time Curve (AUC) of LY3540378 [Predose on Day 1 through Day 113]

    PK: AUC of LY3540378
