NCT06734312

Brief Summary

The purpose of this study is to assess the effect of gastric fundal mucosal ablation (GFMA) on weight trajectory following discontinuation of once-weekly semaglutide or tirzepatide in adults with obesity. In this study, GFMA will be performed on patients who have experienced \> 10% weight loss with GLP-1 therapy and who plan to discontinue use of GLP-1 medications for the duration of the study.

Study Arms (1)

Gastric Fundal Mucosal Ablation (GFMA) following discontinuation of GLP-1 therapy

EXPERIMENTAL

Subjects will undergo endoscopic Gastric Fundal Mucosal Ablation (GFMA) following following discontinuation of GLP-1 therapy. This will be performed by an experienced endoscopist specialized in bariatric endoscopy in a single endoscopic session.

Device: Gastric Fundal Mucosal Ablation (GFMA)

Interventions
