Rhea-AI Summary
Gelesis (NYSE: GLS) presented new pre-clinical data at the World of Microbiome Conference in Vienna, showing that their superabsorbent hydrogel, Gel-B, can positively alter gut bacteria communities in high-fat diets, promoting better metabolic health. The study demonstrated significant growth in Akkermansia muciniphila, a beneficial gut bacterium, suggesting Gel-B's potential beyond weight management. Researchers noted improvements in metabolic parameters and gut barrier function, indicating possible advances in obesity treatment.
Positive
Pre-clinical data indicates Gel-B significantly alters gut microbiota for better metabolic health.
Increased levels of Akkermansia muciniphila associated with improved weight and glucose control.
Restoration of Bacteroidetes/Firmicutes ratio linked to obesity management.
Negative
None.
New pre-clinical data presented today at the World of Microbiome Conference suggest adding superabsorbent hydrogelto a high-fat “western-like” diet prevents unfavorable changes in the communities of gut bacteria associated with diet-induced weight gain
BOSTON--(BUSINESS WIRE)--
Gelesis (NYSE: GLS), a consumer-focused biotherapeutics company and the maker of Plenity®, released today a poster presentation at the World of Microbiome annual meeting in Vienna. The pre-clinical study showed administration of one of the company’s proprietary superabsorbent hydrogels, Gel-B, significantly shifted the composition of the microbiome to a profile correlated with better metabolic health, including improved weight and glucose control. Adding Gel-B to a high-fat diet exponentially encouraged the growth of Akkermansia muciniphila, a bacteria associated with thickened mucosal lining of the gut, improved gut barrier function, and lean body mass. Furthermore, benchtop studies indicated that the 3-D structure and unique properties of Gel-B is required to support the increased growth of Akkermansia. These data suggest that superabsorbent hydrogels may offer additional therapeutic mechanisms promoting metabolic health beyond their space occupying properties.

“Obesity is a complex disease and recent research has shown that alterations of the gut microbiome may be one cause. It follows that interventions used to modify the microbiome could be important tools for the treatment of obesity,” said Neil Floch, MD, a bariatric surgeon and expert on obesity treatment at Nuvance Health in Norwalk, CT. “I look forward to seeing more clinical studies on this new class of materials and their potential mechanical benefits on gut health and the microbiome.”
Gelesis’ superabsorbent hydrogels are inspired by the composition and mechanical properties (elasticity or firmness) of ingested raw vegetables. They are taken by capsules with water before a meal to create a much larger volume of small, non-aggregating hydrogel pieces that act locally in the digestive system without adding any additional calories.
This new study aimed to define the gut microbiota associated with observed metabolic improvement and uncover how Gel-B may be driving compositional changes to these microbiota communities. After being fed a high fat diet (45% lard) for 12 weeks, the studied groups of mice were treated with a combination high fat diet and Gel-B, or a control of high fat diet alone for an additional 12 weeks. Fecal samples were collected at study weeks 12, 16, and 24. Results showed that mice fed Gel-B treatment in addition to a high fat diet had gut microbiota changes, including:
Restoration of the Bacteroidetes/Firmicutes ratio, which is often out of balance in patients with obesity
Increase in Verrucomicrobia driven exclusively by Akkermansia muciniphila
The increased abundance of Akkermansia muciniphila was confirmed in benchtop studies, where results indicated that the 3-D structure of Gel-B was required for this phenomenon. Un-crosslinked modified cellulose, a linear fiber with a much lower elastic response which is used as a building block of Gel-B, did not support the growth of this species.
“We were excited to see that, along with weight loss and changes in gut permeability, we saw beneficial changes in the gut microbiota,” said Maria Rescigno, PhD, Group Leader of the Mucosal Immunology and Microbiota Unit at Humanitas University in Milan, and one of the lead investigators on the study. “Most pronounced was an increase in Akkermansia muciniphila, which is known to be associated with metabolic health.”

In previous studies, administration of one of these hydrogels, Gel-B, in addition to a high-fat diet, blunted weight gain, reversed gut atrophy, improved metabolic parameters, and restored gut barrier function.
