Allurion Presents Data From Largest Ever Real-World Experience of 19,428 Patients at The Obesity Society’s Annual Conference

19,428 patients treated with the Allurion Program across 72 countries lost an average of 12.2% of total body weight

Allurion Technologies, Inc. (NYSE: ALUR), a company dedicated to ending obesity, today announced the presentation of two abstracts at Obesity Week 2024, the annual meeting of The Obesity Society.

The first abstract comprises outcomes data from Allurion’s largest real-world cohort on record. The data, gathered from 19,428 patients across 72 countries treated between 2018 and 2023 with the Allurion Program with results tracked digitally through the Allurion Virtual Care Suite, reveals consistent and significant weight loss outcomes with an average weight reduction of 12.2% at four months across the population.

“While a number of clinical trials have been conducted on intragastric balloons, there has been a persistent lack of large-scale, real-world outcomes data,” said Dr. Shantanu Gaur, Founder and CEO of Allurion. “These data demonstrate that the Allurion Program can consistently and repeatedly achieve clinically meaningful weight loss in a vast and diverse population, adding to the data that have already been published on the Allurion Program in over 26 peer-reviewed publications.”

The second abstract reports on outcomes of the Allurion Program for 27 patients previously treated with liraglutide who did not respond to their GLP-1 treatment. 55% had no weight loss and 45% had weight loss of less than 5% with GLP-1 medications. The study showed that these patients achieved an average weight reduction of 17.6% after just four months on the Allurion Program.

“Clinical studies indicate that, depending on the GLP-1 medication, more than a third of patients do not achieve over 10% TBWL at one year, with lower real-world response rates¹. In addition, it can take 3 months to determine whether treatment is working,” said Dr. Ram Chuttani, Chief Medical Officer and Founding Partner of Allurion. “Our findings suggest that the Allurion Program can be a game-changer for patients who do not respond to GLP-1 treatments,” he added.
