a biotechnology company focused on developing first-in-class products to
safely induce weight loss and improve glycemic control, today announced
positive results from a first-in-human study of Gelesis200, its
next-generation product designed for patients with type 2 diabetes.
Gelesis200 is a novel oral capsulated device that seeks to induce weight
loss and improve glycemic control in patients with type 2 diabetes.
Results from the study showed Gelesis200 was generally well-tolerated.
No serious adverse events (AEs) were reported, and the total number of
AEs reported in the active treatment arms was comparable to the total
number of AEs reported in the placebo arms.
“We are pleased with the safety and tolerability Gelesis200 demonstrated
in this first-in-human study,” said Hassan Heshmati, M.D., Chief Medical
Officer of Gelesis. “Our next step will be to assess Gelesis200 in a
three-month proof-of-concept study – expected to read out in the first
half of 2017 – with the goal of ultimately offering a novel weight
management and glycemic control product for patients with type 2
The primary objective of this single-center, randomized, double-blind,
placebo-controlled, two-cohort, four-arm, crossover study was to
evaluate the safety and tolerability of Gelesis200 following two or
three administrations of 2.10 g in a single day – before breakfast and
lunch or before breakfast, lunch and dinner – in adults who are
overweight or have obesity but are otherwise considered healthy. The
study was conducted in 24 male subjects with body mass indexes ranging
from 28 to 33.
The data also indicated that administering Gelesis200 three times in a
single day did not result in more AEs than administering it two times in
a single day. Further, the timing of administration of Gelesis200 (10
minutes versus 30 minutes before a meal) did not affect the number of
The majority of AEs reported in the active treatment arms were mild, the
most common of which were gastrointestinal-related and headache.
Gelesis200 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 glycemic
control in patients with type 2 diabetes. The hydrogel particles are
synthesized through Gelesis’ multi-step, proprietary process using
starting materials that are considered Generally Recognized as Safe
(GRAS) by the U.S. Food and Drug Administration and commonly used in the
Gelesis200 capsules are taken with water prior to a meal, after which
the hydrogel particles are released from the capsules in the stomach and
rapidly absorb water, hydrating to approximately 85 times their original
size to generate a feeling of fullness. Gelesis200’s high elastic
response and accelerated absorption mechanism makes it a prime candidate
for potentially achieving glycemic control in people with type 2
diabetes through multiple mechanisms of action through the GI. Once in
the large intestine, the particles release most of the water, which is
reabsorbed by the body. The microscopic degraded particles are then
eliminated by the body in the same manner as food.
is focused on the development of novel therapies to induce weight loss
and improve glycemic 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 glycemic control in patients with type 2
