Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multi-center, open-label, 2-group randomized pivotal study evaluating a minimally invasive weight loss procedure. The intent is to evaluate the safety and effectiveness of POSE2.0 (sutures placed in the mid + distal body without placement in the fundus), with a moderate intensity diet and exercise program, as compared to diet and exercise alone. The procedure will be performed using the g-Cath EZ Delivery Catheter with Snowshoe Suture Anchors (AKA g-Cath or g-Cath EZ) and associated devices (g-Prox EZ, g-Lix and Transport), known collectively as the Incisionless Operating Platform (IOP).

9. Have not taken any prescription or over-the-counter weight loss medications in the last 6 months, with exception of medications used to manage T2D so long as the subject has been on a stable dose and weight has persisted.
