Gelesis Secures Over $84 Million in New Capital to Support Commercialisation of PLENITY™

Vitruvian Partners leads a $63.4 million equity round, complemented by $21.2 million in new, non-dilutive grant funding and loans to further support commercialisation efforts

BOSTON, Dec. 9, 2019 - Gelesis, a biotechnology company developing a novel hydrogel platform technology to treat obesity and other chronic diseases related to the gastrointestinal (GI) tract, today announced it secured $84.6 million in new capital. In total, Gelesis has obtained nearly $100 million this year to support the US launch of Plenity^TM.

This latest round of equity funding totalling $63.4 million was led by private equity firm Vitruvian Partners and included other investors. The proceeds from the financing will be used primarily to support the US launch of Plenity in the second half of 2020.

"We are delighted to begin this partnership with Vitruvian, whose mission of driving rapid growth and change across industries is very much aligned with our approach to launching this first-of-its-kind product that could potentially make a difference in the lives of people struggling with excess weight," said Yishai Zohar, founder and chief executive officer of Gelesis. "With this new capital, we are well-positioned to enhance our strategic launch initiatives and leverage our early commercial experience as we prepare for large scale commercial availability of Plenity in the US."

Based upon the Gelesis' proprietary manufacturing facility location, the company was also awarded a grant of $12.9 (€11.7) million from the European Regional Development Fund (ERDF), regulated by the Puglia Region of Italy. This builds on the $10.6 (€9.4) million grant announced in April 2019 and brings the total non-dilutive funds secured this year to $23.5 million. The company also further enhanced its financial flexibility by entering into a long-term, low interest $8.3 million loan agreement.

About PLENITY™

PLENITY is an oral, non-systemic, superabsorbent hydrogel which has received FDA clearance as an aid in weight management in overweight and obese adults with a BMI of 25-40 kg/m², when used in conjunction with diet and exercise. It is made by cross-linking two naturally derived building blocks-modified cellulose and citric acid-that create a three-dimensional matrix. PLENITY particles rapidly absorb water in the stomach and homogenously mix with ingested foods. Rather than forming one large mass, it creates thousands of small individual gel pieces with the elasticity (firmness) of solid plant-based foods (e.g., vegetables) without caloric value. The PLENITY hydrogel increases the volume and elasticity of the stomach and small intestine contents and induces a feeling of fullness and satiety. Once it arrives in the large intestine, the hydrogel is partially broken down by enzymes and loses its three-dimensional structure along with most of its absorption capacity. The released water is reabsorbed in the large intestine, and the remaining cellulosic material is eliminated through the body's natural digestive processes. PLENITY is considered a medical device because it achieves its primary intended purpose through mechanical modes of action consistent with mechanobiology constructs.  For more information, visit myplenity.com.

Important Safety Information

●  PLENITY is contraindicated in patients who are pregnant or are allergic to cellulose, citric acid, sodium stearyl fumarate, gelatin or titanium oxide.

●  PLENITY may alter the absorption of medications. Read Sections 6 and 8.3 of the Instructions for Use carefully.

●  Avoid use in patients with the following conditions: esophageal anatomic anomalies, including webs, diverticuli, and rings; suspected strictures (such as patients with Crohn's disease); or complications from prior gastrointestinal (GI) surgery that could affect GI transit and motility.

●   Use with caution in patients with active GI conditions such as gastro-esophageal reflux disease (GERD), ulcers or heartburn.

●   Overall, the most common treatment related adverse events (TRAEs) were GI-related with 38% of adults in the PLENITY group and 28% of adults in the placebo group.

●  The overall incidence of adverse events (AEs) in the PLENITY group was no different from the placebo group.

Rx Only. For the safe and proper use of PLENITY, refer to the Instructions for Use.

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. Gelesis anticipates Plenity will be available by prescription in the US in the second half of 2020. Additionally, Gelesis is developing its second investigational candidate, Gelesis200, a hydrogel optimised for weight loss and glycaemic control in patients with type 2 diabetes and prediabetes. This novel Gelesis hydrogel technology is also being advanced in other GI conditions, such as non-alcoholic steatohepatitis (NASH) and Chronic Idiopathic Constipation (CIC).

The Gelesis executive and advisory team includes some of the world's leading experts in obesity, materials science, chronic disease research, and commercialisation. Gelesis was co-founded by PureTech Health (LSE: PRTC), a clinical-stage biotechnology company dedicated to discovering, developing and commercialising highly differentiated medicines for devastating diseases.
