Fractyl Health, Inc. (GUTS) reported that its pivotal REMAIN-1 study met its six-month co-primary endpoint. The trial evaluated the company's Revita procedural therapy against a sham procedure for maintaining weight loss after GLP-1 medication. Results demonstrated a statistically significant reduction in weight regain for patients receiving Revita, with 80% of initial weight loss retained compared to 67% in the control group. Additionally, 32% of Revita patients maintained stable weight or lost more weight, compared with 18% in the sham group, and no procedure- or device-related serious adverse events were observed.

The trial results indicate that the Revita system may offer a durable non-drug alternative to help individuals retain body weight reduction after stopping or reducing weight-loss drugs. The data also highlighted a clear dose-response relationship, as participants receiving full ablation experienced 53% less weight regain than the control group. Showing a favorable safety record alongside statistically significant efficacy strengthens the therapeutic rationale for post-GLP-1 maintenance therapy.

Looking ahead, Fractyl Health plans to submit a De Novo application to the U.S. Food and Drug Administration in the fourth quarter of 2026. Investors and clinicians will also look for 12-month trial outcomes expected in the first quarter of 2027 to confirm long-term efficacy and safety ahead of potential market entrance.
