PureTech's Gelesis Presents New Data at Annual ObesityWeek Congress

PureTech Health plc ("PureTech", LSE: PRTC), a cross-disciplinary biotech company developing 21(st) century medicines, is pleased to note that Gelesis today presented new data from its proprietary hydrogel platform at ObesityWeek 2016, the annual combined congress of the American Society for Metabolic and Bariatric Surgery and The Obesity Society. Data from a first-in-human study of its second product candidate, Gelesis200, demonstrated that administration 10 minutes prior to a meal increased fullness throughout the entire day (P = 0.012) as well as satiety immediately preceding dinner and at 150 minutes and 180 minutes after dinner (P = 0.032 and P = 0.031, respectively). The initial safety results of this study were reported in May 2016 and showed that Gelesis200 was well-tolerated and had a similar safety profile to placebo.

Pharmacokinetic data from its lead, pivotal-stage product, Gelesis100, were also presented and showed that administration of Gelesis100 with metformin hydrochloride 850 mg (immediate release tablet) was safe, well-tolerated, and affected metformin pharmacokinetics similarly to food alone.

Joe Bolen, PhD, Chief Scientific Officer for PureTech Health said: "These clinical results for both Gelesis100 and Gelesis200 represent an important step forward in weight management and glycaemic control in people who are overweight or have obesity as well as those who have prediabetes or type 2 diabetes. We look forward to advancing the Gelesis hydrogel engineering platform to address important medical needs."

Administration of Gelesis200 Increases Fullness and Satiety in People who are Overweight or Have Obesity

Data Presented at Annual ObesityWeek Congress

BOSTON, Massachusetts, November 4, 2016 -- Gelesis, focused on developing first-in-class products to safely induce weight loss and improve glycaemic control, today presented new data for its second product candidate, Gelesis200, at ObesityWeek 2016, the annual combined congress of the American Society for Metabolic and Bariatric Surgery and The Obesity Society. Data from this first-in-human study demonstrated that administration 10 minutes prior to a meal increased fullness throughout the entire day (P = 0.012).

The purpose of the analysis was to determine the effect of Gelesis200 on subject-reported appetite scores following two or three administrations in a single day. In addition to increasing feelings of fullness, administration of Gelesis200 10 minutes prior to breakfast, lunch, and dinner resulted in greater satiety immediately preceding dinner (P = 0.017) and at 150 minutes and 180 minutes after dinner (P = 0.032 and P = 0.031, respectively). Gelesis200 was well-tolerated and its safety profile was similar to placebo in this study.

"Gelesis200 is the second product comprised from our proprietary hydrogel platform, and it has been designed specifically for weight management as well as glycaemic control," said Hassan Heshmati MD, Gelesis Chief Medical Officer. "Together with the safety and tolerability results announced earlier this year from the same study, these new data support the advancement of Gelesis200."

Gelesis also presented pharmacokinetic data for its lead, pivotal-stage product, Gelesis100, which showed that administration of Gelesis100 with metformin hydrochloride 850 mg (immediate release tablet) was safe, well-tolerated, and affected metformin pharmacokinetics similarly to food alone. Since metformin is typically administered with food, these results demonstrated that Gelesis100 could potentially be used safely for weight management in patients with type 2 diabetes who take metformin.

About Gelesis100

Gelesis100 is a pivotal stage treatment for weight loss and glycaemic control, which has demonstrated statistically significant weight loss and safety in its previous studies. The treatment is an orally administered capsule containing small hydrogel particles designed to employ multiple mechanisms of action along the gastrointestinal (GI) tract to induce weight loss and improve glycaemic control. The hydrogel particles, which form a new chemical entity, are synthesized through Gelesis' multi-step, proprietary process using starting materials which are considered Generally Recognized As Safe (GRAS) by the U.S. Food and Drug Administration (FDA) and commonly used in the food industry.

Gelesis100 capsules are taken with water prior to a meal, after which the thousands of small hydrogel particles in each capsule are released from the capsules in the stomach and rapidly absorb water, hydrating to approximately 100 times their original size. The hydrogel particles mix homogeneously with food and travel through the GI tract, inducing weight loss and improving glycaemic control. Once in the large intestine, the particles release most of the water, which is reabsorbed by the body. The microscopic degraded particles are then safely eliminated by the body in the same manner as food.

About Gelesis200

Gelesis200 leverages the proprietary hydrogel technology of Gelesis100 but has been engineered with different physical properties. It takes up slightly less volume than Gelesis100; however, it has more rapid hydration and greater elasticity and viscosity. These characteristics are designed to enhance glycaemic control and weight loss for patients who have prediabetes or type 2 diabetes. Like Gelesis100, Gelesis200 is an orally administered capsule containing small hydrogel particles synthesized through Gelesis' multi-step, proprietary process using starting materials that are considered GRAS by the FDA and commonly used in the food industry.

About Gelesis

Gelesis is focused on the development of novel therapies to induce weight loss and improve glycaemic control in people who are overweight or have obesity, including those with prediabetes and type 2 diabetes. Gelesis100, one of the company's product candidates and a first-in-class therapeutic, is currently being evaluated in a six-month pivotal study. Gelesis is also developing Gelesis200, created from the same proprietary technology platform as Gelesis100, as a product optimized to induce weight loss and improve glycaemic control in patients with type 2 diabetes.

The Gelesis advisory team is comprised of leading experts in obesity and its related comorbidities, clinical research and development and advanced biomaterials, including Caroline Apovian, M.D., Professor of Medicine and Pediatrics at Boston University School of Medicine; Louis J. Aronne, M.D., FACP, Director of the Comprehensive Weight Control Program at Weill Cornell Medicine; Arne Astrup, M.D., Head of Department of Nutrition, Exercise and Sports at University of Copenhagen; Ken Fujioka, M.D., Director of the Nutrition and Metabolic Research Center and the Center for Weight Management at the Scripps Clinic; Allan Geliebter, Ph.D., Senior Attending Psychologist, St. Luke's-Roosevelt Hospital; James Hill, Ph.D., Professor of Medicine and Pediatrics, University of Colorado; Lee M.
