Study start date: February 4, 2020

Actual date on which the first participant was enrolled.

This clinical trial aims to explore the effects of an endoscopic procedure called Endoscopic Sleeve Gastroplasty (ESG) in comparison to standard medical treatment. The study focuses on individuals who are managing their weight and related health factors. By comparing ESG to standard medical care, the trial seeks to understand if ESG can offer improved outcomes. The potential benefits could include enhanced weight loss, better management of metabolic risk factors, improved quality of life, increased feelings of fullness, and changes in gut bacteria and digestive system function. The study lasts for 36 months and includes an open-label extension where participants in the standard therapy group may opt for the ESG procedure if they do not achieve sufficient weight loss results after 6 months. During the study, participants in the ESG group undergo the endoscopic procedure, while those in the standard therapy group receive conventional medical care. The primary goal is to measure the total body weight loss percentage. Secondary goals include assessing changes in metabolic risk factors like cholesterol levels, body measurements, body composition, quality of life, gastroesophageal reflux disease, non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, feelings of fullness, and gut bacteria. Additionally, the study will explore changes in gut hormones and digestive system function. Participants who do not achieve significant weight loss results in the standard therapy group may have the option to undergo the ESG procedure after 6 months.
