Systematic review of 11 studies involving 2,107 patients reports average weight reduction of 12.5% with significant improvements in metabolic health

Allurion Technologies, Inc. (NYSE: ALUR), a company dedicated to ending obesity, today announced the publication of a systematic review and meta-analysis evaluating the effectiveness and safety of the Allurion Program. The analysis reviewed studies conducted between 2016 and 2024 and included data from 11 observational studies comprising a total of 2,107 patients.

The results of the meta-analysis demonstrated a mean weight reduction of 12.5% and significant reduction in body mass index (BMI) of 4.75 kg/m² at four months. Importantly, the analysis also confirmed the safety of the Allurion Balloon, with a rate of serious adverse events reported of just 0.90%.

“The safety and effectiveness of the Allurion Balloon have been well-established in 26 peer-reviewed journal articles and with over 150,000 patients treated around the world,” said Dr. Ram Chuttani, Chief Medical Officer and Founding Partner of Allurion. "This new meta-analysis not only highlights the significant reductions in BMI and weight loss achieved by patients but also underscores the metabolic benefits of our program."

The study’s findings are further supported by the observed improvements in metabolic health parameters, particularly in HDL cholesterol, triglycerides, and glycemia, indicating the broad-reaching benefits of the Allurion Program beyond just weight reduction.
