Allurion Announces Publication of New Data Demonstrating Continued Weight Loss at One Year On the Allurion Program

NATICK, Mass.--(BUSINESS WIRE)-- Allurion Technologies, Inc. (NYSE: ALUR), a company dedicated to ending obesity, today announced the publication of a study demonstrating an average weight reduction of 10.5% at four months on the Allurion Program, improving to 13.7% at one year. This data indicate that weight loss can not only be maintained by utilizing the Allurion Program, but it can also be increased by taking advantage of the Program's ongoing virtual guidance and support.

In the study, 486 patients at a single, high-volume bariatric center were treated with the Allurion Balloon and assessed monthly with the Allurion App, Connected Scale, and Health Tracker as part of the Allurion Program. Over one year, participants were given virtual access to a team of registered dieticians. A weekly check-up was conducted for the first month, followed by biweekly check-ups for the subsequent three months, and monthly check-ups for the remaining eight months.

"This study is the largest of its kind in Southeast Asia since the Allurion Balloon was introduced in the region. Results demonstrate that the swallowable gastric balloon is an effective solution for patients seeking to lose weight and keep that weight off," said Dr. Nik Ritza Kosai, Associate Professor and Consultant in Gastrointestinal, Obesity and Metabolic Surgery at The National University of Malaysia and lead author of the study. "Furthermore, our findings offer strong evidence that the combination of balloon intervention and one year of virtual supervision can significantly augment weight loss outcomes."

Previous studies evaluating GLP-1 drugs indicate that after discontinuation of the drug and lifestyle intervention program, patients regained approximately two-thirds of the weight they had lost. ^1-3

"While most weight loss is typically observed within the first four months on the Allurion Program while the balloon is in residence, the findings from this study demonstrate that, for these patients, the combination of the Allurion Balloon with a 12-month, structured, virtual support program significantly contributed to improved weight loss after balloon passage," said Dr. Ram Chuttani, Chief Medical Officer of Allurion. "We believe this study validates our approach of combining the Allurion Balloon with systematic evaluation, monitoring, and guidance, offering a more effective pathway to achieving and maintaining successful weight loss outcomes."
