About

The main purpose of this study is to determine the tolerability and side effects related to LY3875383 given as a single injection under the skin to healthy participants and participants with elevated triglyceride (TG) levels.The study will also assess how fast LY3875383 gets into the blood stream and how long the body takes to get rid of it. Each enrolled participant will receive a single dose of either LY3875383 or placebo.The study will be conducted in four parts (A, B, C and D) and may last up to approximately 28 to 56 weeks including screening.

Enrollment: 41 patients

For Part D:

• Have history of high triglyceride (lipid) level between 150 mg/dL and 500 mg/dL inclusive at pre-screening or based on medical history and confirmed at screening and Low-density lipoprotein cholesterol (LDL-C) level of ≥40 mg/dL.
• Participants must be on a stable moderate or high-intensity dose of a statin for at least 8 weeks before screening and plan to continue the same medication and dose throughout the study duration.
