A Study of LY3971297 in Healthy Participants and Participants With Obesity and Hypertension

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to measure side effects of LY3971297 injection administered under the skin in healthy participants and obese participants with high blood pressure (BP). Blood tests will be performed to check how much LY3971297 gets into the bloodstream and how long it takes the body to eliminate it. This is a 5-part study. The study duration will be approximately 60 days for Part A and approximately 90 days for Parts B, C, D, and E.

For Part C, to qualify as Chinese for the purpose of this study, all the participants' biological grandparents must be of exclusive Chinese descent and born in China For Part Part D, participants with obesity and hypertension must have a stable dose of antihypertensive medications within the past 3 months prior to screening. For Part D, obesity BMI in the range of 30 to 40 kg/m2, inclusive, with a waist circumference of at least 102 cm for men and at least 89 cm for women. For Part E, to qualify as a participant of the first-generation Japanese origin, the participant, the participant's biological parents, and all of the participants' biological grandparents must be of exclusive Japanese descent and born in Japan. Male participants must agree to adhere to contraception restrictions and female participants must be women not of childbearing potential. Exclusion Criteria: Have a history of or current cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, or neurological disorders Have known or ongoing psychiatric disorders that, in the opinion of the investigator, increases the risks associated with study participation Have blood pressure and/or pulse rate constituting a risk as determined by the investigator. Have a systolic BP of less than 100 mmHg. Diagnosed with orthostatic hypotension defined as a decrease in systolic blood pressure of equal to or greater than 20 mmHg or a decrease in diastolic blood pressure of equal to or greater than 10 mmHg when compared with BP from the supine position. For US sites: have donated blood of more than 500 mL within the previous 3 months of screening or intend to donate blood during the course of the study. For Singapore sites: Have donated blood of more than 450 mL or more in the past 3 months or provided any blood donation within the past 1 month before screening Consume more than 10 cigarettes per day (or the equivalent) or are unable or unwilling to abstain from nicotine. Have alcohol intake that exceeds recommended alcohol consumption limits per local regulation, or are unwilling to stop alcohol consumption 24 hours prior to dosing until discharge. For Part D, has concurrent use or anticipated use of phosphodiesterase 5 inhibitor such as vardenafil, tadalafil, and sildenafil, soluble guanylyl cyclase activators (such as riociguat and vericiguat). For Part D, has concurrent or anticipated use of long-acting nitrates or NO donors. For Part D, has concurrent or anticipated use of beta blockers. For Part D, has current use of more than 3 mechanism of actions for treatment of hypertension.
