Obesity Clinical Trial - ACE Stapler Sub Study

Status Completed

Clinical Trial Summary

Obesity and its associated conditions have reached epidemic proportions. Estimates are that about one third of the adults in the United States have obesity. At this moment there are many therapeutic approaches for the treatment of obesity. But, efficacy of most treatment options are limited and so far surgical intervention has been proven to be the only strategy to overcome severe obesity. However, bariatric surgery has limitations and risks, which might be minimized by non-incisional endoscopic procedures.

BaroSense developed a new device, called the Articulating Circular Endoscopic (ACETM) Stapler, which can be used in the treatment of obesity. It is a trans-oral procedure, which intends to reduce the ability of the stomach to expand by creating plications in the region of the fundus and greater curvature. In contrast with other bariatric surgery it is endoscopically performed, reversible and if it fails most future surgical options are still open.

The main study ('Open, prospective study to evaluate the safety and preliminary effectiveness of the BaroSense ACE™ Stapler for the treatment of obesity', multicenter study (MUMC+, AMC and St. Antonius), accepted by MEC AMC) seeks to determine the safety and efficacy of this plicating system for patients with severe obesity.

In this sub-study the investogators want to unravel the exact mechanism and provide more information about the efficacy of the BaroSense ACE™ Stapler. Therefore the authors will measure changes in various parameters that are known to affect weight loss and metabolism, before and after gastric plication (by using the BaroSense ACE™ Stapler) in overweight subjects (these parameters will only be measured in patients at MUMC+). These parameters are post-prandial satiety, food-reward and related brain signalling, gastric emptying, behaviour towards food, food intake, satiety hormone release, microbiota composition and inflammatory markers.

Objectives:

Aim of the present study will be to assess the effect of the BaroSense ACE™ stapler on postprandial satiety, food-reward and related brain signalling, gastric emptying, behaviour towards food, food intake, hormone release, microbiota composition and inflammatory markers.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
