New data show 22.1% weight loss at one year with consecutive Allurion Balloons, approaching weight loss surgery outcomes

NATICK, Mass., June 11, 2024--(BUSINESS WIRE)--Allurion Technologies, Inc. (NYSE: ALUR), a company dedicated to ending obesity, today announced three scientific presentations at the American Society for Metabolic and Bariatric Surgery Annual Meeting (ASMBS) taking place in San Diego, California, June 9-13, 2024.

Data from a study of 121 patients across 11 obesity centers treated with two consecutive, four-month Allurion Balloons showed patients achieved 22.1% weight loss on average at one year. In comparison, studies show that patients treated with 12-month endoscopic intragastric balloons achieve 15.4%1 and 16.2%2 total body weight loss*. "We believe these findings underscore the potential of the Allurion Balloon to deliver superior outcomes to other intragastric balloons, approaching those of weight loss surgery,3,4 for patients seeking effective and safe weight loss solutions," said Dr. Shantanu Gaur, Founder and CEO of Allurion.

Evidence from multiple studies indicates that the Allurion Balloon—a procedureless, liquid-filled balloon—has a significantly lower intolerance rate compared to 12-month endoscopic balloons (1-3% vs 14.4%)5, with an overall serious adverse event rate that averages 10 times less than other liquid-filled balloons*.

Presentations also include data from a study analyzing 1,313 conversations from patients across 26 bariatric clinics in 12 countries and Coach Iris – Allurion’s AI-powered weight loss coach – assessing the safety, accuracy, and overall quality of a beta version released in 2023.

Conversations between patients and Coach Iris were reviewed against a unique framework developed in-house and recently presented at IFSO-EC. Named "FAST," this framework is designed to evaluate and monitor the Fidelity, Accuracy, Safety, and Tone of Coach Iris. The text-based, human-like messaging received satisfaction scores of 84% on Fidelity, 79% on Accuracy, 89% on Safety, and 95% on Tone.

Presentations at ASMBS also include data on the impact of digital appetite tracking and eating behaviors in Allurion Balloon Program patients.
