About Gelesis100

Gelesis100 is a new approach to weight loss that is designed to employ multiple mechanisms of action along the GI tract to promote satiety, induce weight loss and promote GI health. Gelesis100 is non-systemic and administered orally in capsules containing small hydrogel particles, which are made from two natural components that form a novel 3D structure. The novel hydrogel is manufactured through Gelesis’ multi-step, proprietary process and protected by nine families of patents through 2033, several of which have already been allowed or issued in major markets.

Gelesis100 capsules are taken with water prior to a meal, after which the small hydrogel particles are released from the capsules in the stomach and rapidly absorb water, hydrating to approximately 100 times their original size. Gelesis100 is designed to mix homogeneously with food and travel through the GI tract inducing satiety, reducing hunger, and causing weight loss. Once in the large intestine, Gelesis100 partially degrades and releases most of the water, which is reabsorbed by the body. The small gel particles pass through the body without being absorbed and are eliminated in the same manner as food.

Gelesis100 has been studied in more than 450 patients across five clinical studies throughout the United States, Canada, and Europe and in these studies has shown weight loss, increased satiety, reduced hunger, and a consistently strong safety profile.

About Gelesis

Gelesis is developing a novel mechanobiology platform technology to treat obesity and other chronic diseases related to the GI pathway. Gelesis’ proprietary approach is designed to act mechanically in the GI pathway to potentially alter the course of chronic diseases safely and effectively. In September 2017, Gelesis completed a pivotal trial for weight loss evaluating its lead product candidate Gelesis100. Additionally, Gelesis is conducting a proof-of-concept study for its second candidate, Gelesis200, which is optimised for weight loss and glycaemic control in patients with type 2 diabetes and prediabetes. Novel hydrogel mechanotherapeutics based on the Gelesis platform technology are also being advanced through a pipeline with preclinical studies in other GI-related conditions such as non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH) and inflammatory bowel disease (IBD).

The Gelesis executive and advisory team includes some of the world’s leading experts in obesity, chronic disease research, and clinical development, as well as materials science innovators, commercialisation experts, and entrepreneurs.
