Fractyl Health Completes Randomization in REMAIN-1 Pivotal Cohort of Revita® for Post-GLP-1 Weight Maintenance
Topline 6-month pivotal data expected in early Q4 2026 with potential FDA marketing application submission expected in late Q4 2026
Company reiterates cash runway guidance into early 2027, beyond anticipated pivotal data readout
BURLINGTON, Mass., Feb. 26, 2026 (GLOBE NEWSWIRE) -- Fractyl Health, Inc. (NASDAQ:GUTS) (the Company or Fractyl), a clinical stage metabolic therapeutics company focused on pioneering novel approaches to treat obesity and type 2 diabetes, today announced completion of participant randomization in its REMAIN-1 Pivotal Cohort, a double-blind, sham-controlled study evaluating Revita® for weight maintenance following GLP-1 therapy discontinuation.
"Completion of randomization in the REMAIN-1 Pivotal Cohort marks an important milestone as we advance Revita toward the definitive clinical evidence we believe will clearly establish its role in post-GLP-1 weight maintenance," said Harith Rajagopalan, M.D., Ph.D., Co-Founder and Chief Executive Officer of Fractyl Health. "This study was prospectively designed and statistically powered to demonstrate Revita's effect. The clinical insights from our REVEAL-1 and REMAIN-1 Midpoint Cohorts, as well as ongoing follow-up from our Germany Real-World Registry study, informed both the study design and our confidence in this program. With randomization now complete and our balance sheet positioned to support us through and beyond the pivotal readout, our focus is on disciplined execution as we prepare to report topline 6-month results in early Q4 2026. We are grateful to the participants, investigators, and clinical site teams whose commitment has made this progress possible."
Pivotal Study Designed to Deliver Definitive Evidence
The REMAIN-1 Pivotal Cohort is a randomized, double-blind, sham-controlled study evaluating Revita in adults with obesity (BMI ≥30 kg/m2 and ≤45 kg/m2) who achieved ≥15% total body weight loss on tirzepatide. Following GLP-1 discontinuation, participants were randomized 2:1 to receive Revita or a sham endoscopic procedure. The co-primary endpoints are percent total body weight regain (Revita vs sham) at 6 months, and proportion of participants maintaining ≥5% total body weight loss at 12 months (responder rate). All participants receive standardized diet and lifestyle counseling throughout the study.
"The level of patient interest we experienced at Baylor was remarkable. We ultimately trained three endoscopists and installed two consoles to perform the Revita procedure to meet demand during the study," said Mohammed Othman, M.D., Professor of Medicine, Baylor College of Medicine, and a REMAIN-1 Investigator. "Weight regain after GLP-1 discontinuation is a challenge I see regularly in clinical practice, and the enthusiasm from both patients and referring physicians throughout this trial reflects a real and urgent unmet need."
2026 Revita Clinical and Regulatory Milestones
Fractyl is advancing toward multiple anticipated clinical and regulatory milestones across its REMAIN-1 weight maintenance program, supporting a clear and sequential path toward pivotal readout and potential U.S. regulatory submission:
- Q2 2026: U.S. Food and Drug Administration (FDA) feedback on potential for use of the De Novo pathway for Revita.
- Q2 2026: 1-year REVEAL-1 Cohort data.
- Q3 2026: 1-year REMAIN-1 Midpoint Cohort randomized data.
- Early Q4 2026: Topline 6-month randomized data from REMAIN-1 Pivotal Cohort.
- Late Q4 2026: Potential FDA marketing application submission in post-GLP-1 weight maintenance. The timing and form of submission may be informed by FDA feedback on the potential use of the De Novo pathway for Revita, which is currently expected in Q2 2026.
The Company reiterates its previously announced cash runway into early 2027, making it well-positioned to fund operations through key 2026 clinical and regulatory milestones, including the Revita pivotal readout.
