Conditions

Healthy, Type 2 Diabetes Mellitus

Brief summary

The main purpose of this study is to assess the safety and tolerability of a single dose of LY3938577 in healthy participants and participants with Type 2 Diabetes Mellitus (T2DM) (Part A) and multiple doses of LY3938577 in participants with T2DM (Part B). The study will last approximately 6 weeks for Part A and approximately 10 weeks for Part B respectively.
