Fractyl Health and Bariendo Sign Letter of Intent to Prepare for Potential Offering of Revita® Across its Bariatric and Metabolic Endoscopy Centers Nationwide

Collaboration is designed to implement a highly scalable clinical pathway for Revita in post GLP-1 weight maintenance, pending FDA approval, potentially benefiting millions of eligible patients

Rising interest from patients and payers for an off-ramp from GLP-1 drugs is fueling significant demand for endoscopic alternatives designed to restore health rather than manage disease

BURLINGTON, Mass. and SAN FRANCISCO, June 04, 2025 (GLOBE NEWSWIRE) -- Fractyl Health, Inc. (Nasdaq: GUTS) (the Company or Fractyl), a metabolic therapeutics company focused on pattern-breaking approaches that treat root causes of obesity and type 2 diabetes (T2D), and Bariendo Inc. (Bariendo), the first all-in-one obesity care platform with cost-effective and durable endoscopic treatments for the rising obesity epidemic, today announced the signing of a non-binding Letter of Intent (the LOI) to explore a future collaboration centered on Fractyl’s investigational Revita procedure as a durable off-ramp for weight maintenance following GLP-1 drug discontinuation.

This agreement comes as Fractyl prepares for three key data readouts from its ongoing pivotal study of Revita: REVEAL-1 Cohort open-label data expected in June 2025; REMAIN-1 Midpoint Cohort data expected in the third quarter of 2025; and 6-month primary endpoint data from the REMAIN-1 Pivotal Cohort expected in the second half of 2026. Together, these clinical milestones are designed to demonstrate Revita’s potential to help maintain weight loss after GLP-1 discontinuation and inform its possible role in supporting durable metabolic outcomes.

Revita is an outpatient endoscopic procedure that involves resurfacing the mucosal lining of the duodenum, the first part of the small intestine just after the stomach, which is responsible for breaking down food into absorbable nutrients. Revita targets the duodenal lining, which can become thickened by high-fat and high-sugar diets, altering key nutrient sensing and signaling mechanisms in the gut and driving obesity and metabolic disease. By resurfacing and reversing the pathology of the duodenal lining, if approved by the U.S. Food and Drug Administration (FDA), Revita has the potential to become the first disease-modifying therapy that targets a root cause of obesity.

Bariendo brings to the partnership a scalable, physician-driven platform designed to deliver a holistic approach to obesity, including metabolic endoscopic solutions at the nation’s largest network of high-volume hospital and ambulatory endoscopy centers across the United States. Bariendo’s mission is to commercialize and scale long-term solutions to obesity that don’t require ongoing medication use, empowering people to live healthier lives free from the burden of chronic disease. This model is well-aligned with the purpose of Revita, which is being developed as potentially the first outpatient endoscopic procedure targeting post-GLP-1 weight maintenance.

The explosion of GLP-1 usage has led to the observation that most patients rapidly discontinue drug therapy and face the risk of rapid weight regain after stopping their drugs. Fractyl and Bariendo see an urgent need for an effective “off-ramp” solution that may enable patients to maintain their hard-won weight loss without chronic pharmacology. Under the terms of the LOI, Bariendo has expressed its intent to work with Fractyl to develop its operational readiness and planning for potential integration of Revita into its clinical offerings, pending FDA approval. The collaboration will focus on pre-commercial preparation, including clinical workflow design, provider education, health economic analysis, and the development of referral pathways.



“Obesity is one of the most prevalent diseases in America¹, and a major contributor to the nation’s leading causes of death, like heart attacks, diabetes, and cancer. Bariendo is aiming to address this global health crisis with patient-centric, science-based solutions, combining the latest in endoscopic procedures, anti-obesity medicine and concierge care,” said Dr. Christopher Thompson, Co-Founder of Bariendo. “We have observed tremendous inbound interest from patients and payers for an off ramp from GLP-1s and are excited to partner with Fractyl as they develop Revita, which we believe has the potential to address the largest remaining unmet need in obesity: weight maintenance.”

“This agreement reflects growing recognition of Revita’s potential to address a major unmet need in post-GLP-1 care, as reflected in recruitment velocity in our REMAIN-1 pivotal study,” said Harith Rajagopalan, M.D., Ph.D., Co-Founder and Chief Executive Officer of Fractyl. “In the study, we have observed extraordinary interest from patients and providers in a holistic approach to durable weight maintenance that includes a time-limited period of weight loss ‘induction therapy’ with GLP-1 drugs followed by weight maintenance with Revita and diet/lifestyle intervention. Bariendo is an ideal partner to enable the translation of this care pathway in the REMAIN-1 study to accelerate widespread clinical adoption of Revita pending FDA approval. We believe this collaboration with Bariendo is an important early step toward shaping how durable metabolic interventions will be delivered at scale.”

About Fractyl Health

Fractyl Health is a metabolic therapeutics company focused on pioneering new approaches to the treatment of metabolic diseases, including obesity and T2D. Despite advances in treatment over the last 50 years, obesity and T2D continue to be rapidly growing drivers of morbidity and mortality in the 21st century. Fractyl’s goal is to transform metabolic disease treatment from chronic symptomatic management to durable disease-modifying therapies that target the organ-level root causes of disease.

About Revita^®

Fractyl Health’s lead product candidate, Revita, is based on the Company’s insights surrounding the potential role of the gut in obesity. Revita is designed to remodel the duodenal lining via hydrothermal ablation (i.e. duodenal mucosal resurfacing) to reverse damage to intestinal nutrient sensing and signaling mechanisms caused by chronic high-fat and high-sugar diets that are a root cause of metabolic disease. In the U.S., Revita is for investigational use only under U.S. law. Revita has U.S. FDA Breakthrough Device designation in weight maintenance for people with obesity who discontinue GLP-1 based drugs. A pivotal study of Revita in patients with obesity after discontinuation of GLP-1 based drugs, called REMAIN-1, was initiated in the third quarter of 2024 and has completed enrollment.
