(RTTNews) - Fractyl Health, Inc. (GUTS) announced positive one-year randomized data from the REMAIN-1 Midpoint Cohort, demonstrating that its Revita duodenal mucosal resurfacing (DMR) system can help maintain weight loss after stopping GLP-1 therapy.

Fractyl Health is a clinical-stage metabolic therapeutics company focused on novel procedural approaches to obesity and type 2 diabetes management. Its Revita DMR system designed to provide a durable weight maintenance beyond pharmacologic therapy.

REMAIN-1 is a randomized, sham-controlled study evaluating Revita in patients who discontinued GLP-1 therapy. The Midpoint Cohort included 45 participants. The trial was designed to assess whether Revita could sustain weight loss and reduce weight regain after GLP-1 withdrawal, with FDA-mandated co-primary endpoints measuring weight-maintenance durability and responder rates.

•In the modified intention-to-treat population (N=45), a single Revita procedure reduced weight regain by approximately 40% versus sham at one year (7.8% vs 13.0% of body weight).

•Patients receiving complete duodenal ablation (>14 cm) maintained approximately 81% of GLP-1-induced weight loss at one year compared with 48% in sham participants, reflecting a >60% reduction in weight regain.

•In an optimized subgroup with higher GLP-1 run-in weight loss (=17.5%) approximately 84% of GLP-1-induced weight loss at one year versus 46% with sham.

•The FDA-mandated co-primary endpoint of responder rate (maintaining at least 5% total body weight loss at one year) was achieved by 73% of Revita patients in the Midpoint Cohort, rising to 91% in those with complete ablation.

These results reinforce Revita's potential as the first durable procedural therapy for post-GLP-1 weight maintenance, addressing a critical unmet need for patients who struggle with weight regain after discontinuing injectable therapies.

Fractyl anticipates topline six-month randomized data from the REMAIN-1 Pivotal Cohort in early Q4 2026, followed by a potential FDA De Novo marketing application submission in late Q4 2026.
