About Gelesis

Gelesis is developing a novel hydrogel platform technology to treat overweight and obesity and 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 certain chronic diseases. In April 2019, Gelesis received FDA clearance for its lead product candidate, Plenity™, as an aid for weight management in overweight and obese adults with a Body Mass Index (BMI) of 25-40 kg/m2, when used in conjunction with diet and exercise. Plenity is currently available in limited supply in the U.S. Additionally, Gelesis is developing its second investigational candidate, Gelesis200, a hydrogel optimized for weight loss and glycemic control in patients with type 2 diabetes and prediabetes. Novel hydrogel mechanotherapeutics based on the Gelesis platform technology are also being advanced in other GI inflammatory conditions, such as non-alcoholic steatohepatitis (NASH) and Chronic Idiopathic Constipation (CIC).

Gelesis was also named one of Fast Company’s Most Innovative Companies for 2020.

The Gelesis executive and advisory team includes some of the world’s leading experts in obesity, materials science, chronic disease research, and commercialization. Gelesis was co-founded by PureTech Health (LSE: PRTC). For more information, visit or connect with us on Twitter @GelesisInc.
