ClinConnect Summary

This clinical trial is designed to compare two treatments, semaglutide injection and Wegovy®, to see which one helps people lose more weight. The study is focused on adults aged 18 to 75 who have a body mass index (BMI) of 28 or higher and have previously tried to lose weight without success. To participate, individuals must be willing to sign a consent form and meet certain health criteria, such as not having specific blood sugar issues or severe mental health conditions.

Participants in this trial can expect to receive either the semaglutide injection or Wegovy® for a set period, and their weight loss progress will be monitored. The trial is not yet recruiting participants, so there’s still time to learn more before it begins. It’s important for interested individuals to consider their overall health and any recent weight changes or treatments they’ve had, as these factors will determine their eligibility for the study.
