A Study of LY3502970 in Chinese Participants With Obesity or Are Overweight With Weight-related Comorbidities

June 19, 2026 updated by: Eli Lilly and Company

A Multiple Dose Titration Study to Investigate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of LY3502970 in Chinese Participants Who Have Obesity or Are Overweight With Weight-related Comorbidities

The main purpose of this study is to learn about the safety and tolerability of LY3502970 when given to Chinese participants with obesity or overweight with weight-related comorbidities. Blood tests will be performed to investigate how the body processes the study drug and how the study drug affects the body. Each enrolled participant will receive LY3502970, or placebo given orally. For each participant, the study will last about approximately 22- and 30-weeks for both cohort 1 and 2, respectively including screening period.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
