ClinConnect Summary

This clinical trial is studying a new treatment called GV101 to see how well it helps with weight loss in people who are obese. The trial is designed for adults aged 18 to 70 years who have a body mass index (BMI) between 30 and 45, which means they are considered to have obesity. To be eligible, participants should be generally healthy, have not experienced significant weight changes in the past three months, and be willing to maintain their current diet and exercise routines.

Participants in the trial will receive GV101 or a placebo (a treatment without the active drug) for 16 weeks, and the researchers will measure how much weight they lose compared to those who received the placebo. It's important for potential participants to know that they will need to follow specific guidelines, including avoiding certain medications and lifestyle changes during the study. The trial is not yet recruiting participants, so there will be more information available soon for those who are interested in getting involved.
