A Study of Baricitinib (LY3009104) in Healthy Chinese Participants

Phase 1

Completed

Brief Summary: The main purpose of this study is to investigate the safety and tolerability of the study drug known as baricitinib in healthy Chinese participants. The study will measure how the body absorbs, breaks down and gets rid of baricitinib. The study will last about 20 days, not including screening. This study is for research purposes only, and is not intended to treat any medical condition.

Primary Outcome Measures

Name	Time	Method
Number of Participants With One or More Clinically Significant Event(s)	Baseline through Study Completion (up to Day 20)	Clinically significant events were defined as a moderate to severe adverse event, abnormal clinical sign, or clinical laboratory finding that may pose risk to the well-being of the participant. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Event module.
