New Peer-Reviewed Publication Demonstrates Superior Weight Loss and Improved Body Composition with the Allurion Smart Capsule Combined with Lifestyle Intervention Compared to Lifestyle Intervention Alone

NATICK, Mass.--(BUSINESS WIRE)--Allurion Technologies, Inc. (NYSE: ALUR), a pioneer in metabolically healthy weight loss, today announced the publication of a peer-reviewed, case-controlled study on the use of the Allurion Smart Capsule combined with lifestyle intervention compared to lifestyle intervention alone and its impact on weight loss and body composition.

Published in Obesity Surgery, a leading international journal dedicated to the treatment of obesity and metabolic disease, results from the study demonstrate a significantly higher weight reduction, fat mass loss, and visceral fat loss in patients treated with the Allurion Smart Capsule combined with lifestyle intervention compared to those receiving lifestyle intervention alone. At 36 weeks, Allurion Smart Capsule patients had an average weight reduction of 20% with favorable body composition changes.

The study included 1,143 patients with a body mass index (BMI) of ≥ 30 kg/m².

"This study underscores the synergistic effects of the Allurion Smart Capsule with an individualized lifestyle intervention, with average weight reduction of 20% and nearly twice as much fat reduction at 36 weeks without adverse effects on muscle mass," said Dr. Yannis Raftopoulos, Director of the Weight Management Program at Holyoke Medical Center and Principal Investigator. "This study demonstrated a safety profile better than bariatric surgery and GLP-1 therapy and an efficacy comparable to bariatric surgery and better than real-world, high-dose GLP-1 therapy at a substantially lower cost. This approach has the potential to set a new benchmark in obesity management not only by achieving significant weight loss but also by improving body composition—something not previously reported."

The publication of this peer-reviewed study further bolsters an extensive data set on the safety and efficacy of the Allurion Smart Capsule.

“With over 30 peer-reviewed publications on the Allurion Smart Capsule, we believe there is little doubt that it has a unique value proposition for patients with obesity,” said Dr. Shantanu Gaur, Founder and CEO of Allurion. “This publication demonstrates that using an individualized lifestyle intervention program in conjunction with the Allurion Smart Capsule can lead to significant weight loss with clear improvements in body composition, something patients who undergo bariatric surgery or high-dose GLP-1 therapy struggle to achieve.”

The Allurion Smart Capsule is designed to be swallowed during a brief outpatient visit, filled once in the stomach, and pass naturally after four months. When combined with Allurion’s Virtual Care Suite, patients also receive digital support and remote monitoring aimed to change behaviors and improve outcomes.
