Summary

This trial is testing a new drug called LY3971297, which is given as an injection under the skin. The study includes both healthy people and obese people with high blood pressure. Researchers will take blood samples to see how much of the drug enters the bloodstream and how long it stays in the body.

Who is the study for?
This trial is for healthy individuals or those with obesity and high blood pressure. Healthy participants should have a BMI of 18.5 to 35 kg/m2, while obese participants need a BMI of 30 to 40 kg/m2 and meet specific waist measurements. Certain parts require Chinese or Japanese descent. Participants must not have significant health issues, psychiatric disorders, risky blood pressures, recent large blood donations, heavy nicotine or alcohol use, nor take certain medications.
What is being tested?
The study tests LY3971297 injections in different groups: healthy people and those with obesity plus high BP. It checks the drug's safety profile by observing side effects and measures how it's absorbed and cleared from the body over approximately two to three months.
What are the potential side effects?
Specific side effects are not listed but will be monitored throughout the trial as part of its purpose is to measure them when LY3971297 is administered under the skin.
