Gelesis, a clinical stage biotechnology company focused on the development of first-in-class products to safely induce weight loss and improve glycemic control, announced today that it has closed a $31.5 million growth financing round. New institutional investors, including Cormorant Asset Management, joined current investors Invesco Asset Management, PureTech and the Priztker/Vlock Family Office in this financing round.

The financing brings the total capital raised since inception to over $90 million.

Gelesis plans to use the proceeds from the financing to enable completion of a six-month U.S. Food and Drug Administration (FDA) pivotal trial of Gelesis100 with topline data expected to be available in the first half of 2017, as well as to support commercial readiness activities in preparation for a potential launch.

Gelesis100 is a first-in-class, orally administered capsule containing small hydrogel particles designed to employ multiple mechanisms of action along the gastrointestinal tract to safely induce weight loss and improve glycemic control in overweight and obese patients.

In a multicenter, double-blind, placebo-controlled proof-of-concept study, Gelesis100 showed statistically significant weight loss in overweight and obese subjects, with particularly dramatic weight loss in prediabetics. In July 2015, Gelesis announced the expansion of the Gelesis100 GLOW study to multiple U.S. sites, allowing it to serve as a U.S. pivotal trial. The expansion of the GLOW study accelerated the clinical timeline by approximately one year, and Gelesis anticipates enrolling patients in U.S. sites in 2016 and filing for FDA approval in the first half of 2017.

Funds will also be used for the expected completion of first-in-human studies of its glycemic control product, Gelesis200, with anticipated read-out of a three-month proof-of-concept study expected in the second half of 2016. Gelesis200 was created with the same proprietary technology platform as Gelesis100 and its properties are optimized to improve glycemic control in patients with prediabetes and type 2 diabetes who may or may not require weight loss.

'We appreciate the support of Gelesis' new and existing investors as we aim to bring novel therapies to the market to address the obesity and diabetes epidemics,' said Yishai Zohar, Co-founder and Chief Executive Officer of Gelesis.

'We look forward to completing our U.S. pivotal trial of Gelesis100 and, if approved, we believe it has the potential to address the significant unmet need for an orally dosed, safe and efficacious therapy to induce weight loss and improve glycemic control.'
