After stopping weight-loss drugs, people given a procedure kept about 80% of lost weight
Fractyl Health (GUTS) reported positive six-month results from its REMAIN-1 study, showing that patients treated with its Revita DMR System maintained 80% of weight loss after stopping GLP-1 therapy, compared to 67% in the control group. The study met its primary endpoint with high statistical significance. Fractyl plans to submit a De Novo marketing application to the FDA in late 2026 and anticipates a potential U.S. launch in early 2028. The company will host a webcast to discuss the results.
