ClinConnect Summary

This clinical trial is studying a medication called semaglutide to see how it can help people manage their weight after quitting smoking. The trial focuses on understanding how semaglutide affects body weight and appetite control in individuals who have recently stopped smoking. It is currently looking for participants aged between 18 and 75 who have a body mass index (BMI) of 27 or higher and have been smoking at least five cigarettes a day for the past year. Participants must also be motivated to quit smoking within the next month.

If you decide to participate, you will receive the medication and be monitored throughout the study. You will need to attend regular appointments and may undergo some tests to ensure your health and safety during the trial. It's important to note that certain health conditions, medications, or recent surgeries could prevent you from joining. Overall, this trial aims to help develop better strategies for weight management for those who have quit smoking, which can be a significant challenge for many.
