Our Approach

Gelesis100 is a first-in-class therapeutic that is designed to treat the physiological symptoms of hunger without surgery, other invasive procedures or systemically absorbed drugs. It is designed to safely cause significant weight loss.

Gelesis100 is designed to trigger several important weight loss mechanisms in the stomach and small intestine. The product is a highly engineered and proprietary patented hydrogel whose components are materials with Generally Recognized as Safe (GRAS) designation. We believe Gelesis100 represents a breakthrough in material science and has been designed and finely tuned to act in specific ways throughout the gastrointestinal tract (see below):

Our Technology

Gelesis100 capsules administered with water prior to a meal

Particles released & expand in stomach by absorbing water

background image

Particles mix homogenously with food and designed to enhance satiety due to increased volume & elasticity of stomach contents

background image

Increased elasticity of stomach contents designed to delay gastric emptying as stomach contents flow into small intestine

background image

Particles designed to create a diffusion barrier that slows absorption of glucose in small intestine

background image

Particles partially degrade in the large intestine, water is released & reabsorbed by body, and particles are eliminated from body
