Brief summary

The purpose of this study is to evaluate how well LY3375880 (study drug) is tolerated in healthy participants and what side effects may occur. The study drug will be administered either subcutaneously (SC) under the skin or intravenously (IV) into a vein in the arm. This is a two-part study. Participants will enroll in only one part. Part one will last about 16 weeks including screening and follow-up. This part will include 2 nights at the study site. Part two will last about 20 weeks including screening and follow-up. This part will include 2 nights at the study site for each dose.
