Summary

This study tests a weekly oral medication called ecnoglutide (VRB-101) to see if it can help people with obesity or overweight maintain their weight. Participants must have already been on weekly injections of semaglutide or tirzepatide for at least 6 months. The goal is to find the best dose for weight maintenance while monitoring safety and side effects.
