Fractyl Health Reports Potent and Durable Two-Year Real-World Outcomes with Revita® Showing Sustained Weight Loss and Improved Glucose Control After a Single Procedure
Rhea-AI Summary
Fractyl Health (NASDAQ:GUTS) has reported compelling two-year real-world outcomes for its Revita® procedure from the Germany Real-World Registry study. The data shows a median 9.6% weight loss and 1.6% HbA1c reduction in patients with type 2 diabetes, sustained over two years after a single procedure.
The study involved 9 participants with a median baseline weight of 104 kg and HbA1c of 9.6%. After treatment, 7 out of 8 participants achieved ≥5% weight reduction, with median HbA1c improving from 9.6% to 7.0% at two years. Notably, no device or procedure-related serious adverse events were reported.
The company expects key data readouts from its pivotal REMAIN-1 study in Q3 2025, focusing on post-GLP-1 weight maintenance, with primary endpoint data anticipated in H2 2026.
Positive
- Sustained median weight loss of 9.6% maintained for two years after single procedure
- Significant HbA1c reduction of 1.6% maintained through 2-year follow-up
- No device or procedure-related serious adverse events reported to date

- Results consistent across both controlled studies and real-world settings
Negative
- Small sample size of only 9 participants with 2-year follow-up data
- One participant experienced 4.5% weight gain
- Three patients remained dependent on GLP-1 drugs throughout the study period

New real-world findings are consistent with prior two-year clinical data from studies conducted outside the United States, reinforcing Revita’s potential for long-term metabolic control ahead of pivotal REMAIN-1 readouts
Company anticipates key data readouts from randomized Revita studies in post-GLP-1 weight maintenance starting in Q3 2025
BURLINGTON, Mass., Aug. 05, 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 2-year follow-up data from the Germany Real-World Registry study that showed a single Revita procedure led to durable weight loss and improved glucose control in people with obesity and advanced T2D. These data underscore Revita’s potential to provide a potent and durable non-drug alternative for patients struggling with long-term metabolic control.
Two-Year Data in Germany Show Sustained Weight Loss and Glycemic Improvement in Patients with Obesity and Advanced T2D
The Germany Real-World Registry study is a prospective, post-market, clinical follow-up study to evaluate the Revita procedure in patients with inadequately controlled T2D. Participants had a baseline HbA1c between 7–
At baseline, the first 9 participants with 2 years of follow-up had a median age of 62 years, median weight of 104 kg (229 lbs.; BMI 32 kg/m²), and a median HbA1c of
After a single Revita procedure, these 9 participants achieved a median weight loss of
In this cohort, weight loss and glucose improvements began as early as one month after the Revita procedure and were sustained through 2 years of follow-up (see data table). These findings highlight the potential of a single Revita treatment to deliver durable weight maintenance in a real-world setting.

“We now have real-world evidence that a single Revita procedure can deliver durable improvements in both weight and glucose control that last for two years,” said Harith Rajagopalan, M.D., Ph.D., Co-Founder and Chief Executive Officer of Fractyl Health. “These results reinforce what we saw in earlier clinical studies in people living with obesity and type 2 diabetes. The consistency of these outcomes, across both controlled studies and real-world care, speaks to the potential impact of Revita as a one-time, non-drug solution. With randomized data from our pivotal REMAIN-1 study expected in the third quarter of this year, we are moving closer to offering a new option for long-term weight maintenance after GLP-1 therapy.”
Thirty-four participants are currently enrolled in the Germany Real-World Registry study. While the study is no longer enrolling new patients, Fractyl will continue protocol-defined follow-up of participants and share outcomes on an ongoing basis.
Revita is being studied in an ongoing IDE-approved REMAIN-1 pivotal study to evaluate its potential safety and efficacy in post-GLP-1 weight maintenance. These new findings from Germany add real-world momentum to Fractyl’s upcoming pivotal trial readouts, including Midpoint Cohort data from its ongoing REMAIN-1 study, which is expected in Q3 2025, and primary endpoint data from the Pivotal Cohort, anticipated in H2 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 for patients with obesity.

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 enrollment is now complete.
