A Single-Ascending Dose Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of LY3437943 in Healthy Subjects

This study is being conducted to determine the side effects related to LY3437943 given as a single injection under the skin to healthy participants. Blood tests will be performed to check how much LY3437943 gets into the bloodstream and how long the body takes to get rid of it. Each enrolled participant will receive a single dose of LY3437943 or placebo. The study will last up to approximately 71 days for each participant, including screening.
