Fractyl Health Announces Groundbreaking Data from REMAIN-1 Midpoint Cohort Showing Revita^®

Maintained Weight Loss After GLP-1 Discontinuation

Pilot study met key 3-month efficacy endpoint with strong statistical significance (p=0.014); Revita-treated patients lost an additional 2.5% total body weight after stopping GLP-1 drugs vs. 10% regain in sham-treated patients

Revita procedure demonstrated excellent safety and tolerability to date, consistent with prior clinical studies

Results validate pivotal study design and reinforce Revita’s potential to be the first therapy for post-GLP-1 weight maintenance

BURLINGTON, Mass., September 26, 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), today announced groundbreaking results from the REMAIN-1 Midpoint Cohort, supporting the potential for Revita to be the first therapy to preserve weight loss after GLP-1 drug discontinuation. At 3 months, Revita-treated patients lost an additional 2.5% total body weight after stopping tirzepatide, while sham patients regained 10% (p=0.014). These results are clinically and statistically significant and provide randomized, blinded evidence that drug-free, durable weight maintenance is possible. They further support Revita as a potential first-in class treatment in a new therapeutic category in obesity care: post-GLP-1 weight maintenance.

“One of the biggest challenges in obesity medicine today is what happens when patients stop GLP-1 therapy, whether because of cost, insurance coverage, or side effects. We know weight regain almost always follows,” said Shelby Sullivan, M.D., Professor of Medicine at the Geisel School of Medicine at Dartmouth University. “The REMAIN-1 3-month results are the first randomized, controlled evidence suggesting that a one-time endoscopic procedure may help maintain drug-free weight loss after GLP-1 discontinuation. The treatment difference we saw in this study, with Revita patients continuing to lose weight while sham patients rapidly regained weight, is striking. If these findings continue to hold with more data, duodenal mucosal resurfacing could represent a novel and much-needed solution to the largest gap in obesity care: post-GLP-1 weight maintenance.”

REMAIN-1 Midpoint Cohort Study Design

The REMAIN-1 Midpoint Cohort (N=45) is a randomized, double-blind, sham-controlled study designed to evaluate Revita in adults with obesity who achieved at least 15% total body weight loss with tirzepatide. After discontinuing the drug, participants were randomized 2:1 to Revita or a sham endoscopic procedure. The key efficacy endpoint was total body weight change in Revita versus sham at 3 months.

The Midpoint Cohort is designed to be identical to the ongoing Pivotal Cohort, serving as an early readout to reinforce confidence in the pivotal program and provide initial validation of the study design and endpoints.

Key Findings

Data shared are for the treatment period of up to 3 months. The Midpoint Cohort is ongoing, with 6-month randomized data expected in Q1 2026.

“These results are a defining milestone for Fractyl and the obesity community. For the first time, randomized, blinded data show that Revita may dramatically prevent weight regain after GLP-1 discontinuation at 3 months. This is a compelling demonstration that targeting the gut may provide a remarkable and clinically significant improvement in obesity,” said Harith Rajagopalan, M.D., Ph.D., Co-Founder and Chief Executive Officer of Fractyl Health. “The implications are profound. Patients want durable weight loss without the need for chronic medical therapy. The Revita clinical profile in this study suggests we have the potential to create a new standard of care in obesity with a disease-modifying intervention that allows us to progress from chasing weight loss to sustaining health with a durable metabolic reset.”

Upcoming Milestones

The REMAIN-1 Midpoint Cohort is ongoing, with 6-month data expected in Q1 2026. The REMAIN-1 Pivotal Cohort has completed enrollment, and the Company remains on track to randomize patients in early 2026 and deliver 6-month topline primary endpoint data and potentially file a PMA in H2 2026. These milestones are designed to evaluate Revita as the first potential therapy for post-GLP-1 weight maintenance and to open a new therapeutic category in obesity care.

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 drugs. A pivotal study of Revita in patients with obesity after discontinuation of GLP-1 drugs, called REMAIN-1, was initiated in the third quarter of 2024 and has completed enrollment.
