ULTIMATE Study for Weight Loss

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to help find out more about how the Primary Obesity Surgery Endoluminal (POSE) procedure makes patients feel less hungry and fuller faster, leading to weight loss. In this study, USGI Medical wants to see if stomach emptying and gastro-intestinal hormone levels change after a POSE procedure with an increased (as compared to typical) number of anchors placed.

Detailed Description
-----------------
This study will use the USGI Medical Incisionless Operating Platform (IOP) to determine the affects of placing more Suture Anchors per patient (as compared to the current practice) in Primary Obesity Surgery Endoluminal(POSE). USGI wants to see if placing more anchors (particularly in the distal body/antrum region) significantly impacts primary weight loss, satiety, and metabolic outcomes.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Weight Loss | Weight loss will be monitored and recorded on a monthly basis for up to 18 months post POSE with the proportion of subjects achieving ≥25% excess weight loss (EWL) at 12 months (Met Life criteria)being the primary efficacy endpoint | 18 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Gastric emptying | This test consists of determining if there is a Clinically significant change in the duration of a radioactive marker (which is non-absorbable, and free of any food components) in a stomach pre and post POSE. In order to carry out this test, a piece of food is marked with a radioactive isotope and, by using an abdominal gamma camera; detections of radioactivity are made in the stomach during the postprandial period. | Immediately Pre-procedure, & 2 & 6 months post procedure |
