A Study of LY3025876 in Participants With Diabetes

This study will also evaluate how much of the study drug enters the blood stream and how long
it takes for the body to remove the study drug. Information about any side effects that may
occur will also be collected. Participants will continue their usual diet and exercise
program and may remain on their physician-prescribed dose of metformin.

Each part of the study is expected to last 10 to 12 weeks on average, not including
screening. Participants may only enroll in one part.
