Allurion Technologies submits PMA to FDA, announces additional AUDACITY data

Allurion Technologies (ALUR) announced submission of the fourth and final module of the pre-market approval application to the FDA and additional, supportive analyses from the AUDACITY Study that meet both of the pre-specified co-primary endpoints. Topline results announced previously showed that the AUDACITY Study met its first co-primary endpoint related to responder rate at 48 weeks. Allurion Balloon subjects also exhibited substantially greater weight loss compared to control subjects at 48 weeks, with a mean difference in total body weight loss of 3.77%, resulting in a 2.69% super-superiority margin. This margin was less than the pre-specified 3% super-superiority margin needed to meet the comparative co-primary endpoint and was impacted, in part, by higher-than-expected weight loss in control subjects. Additional analyses submitted in the PMA application were conducted to account for the results seen in the control group. Using imputation methods that account for the variations observed in the control subjects, the mean difference in weight loss between the treatment and control groups at 48 weeks was 4.34% with a super-superiority margin of 3.14%, exceeding the pre-specified 3% super-superiority margin in the second co-primary endpoint. At 40 weeks, using these imputation methods, the mean difference in weight loss between the treatment and control groups was 4.90% with a super-superiority margin of 3.75%, considerably exceeding the pre-specified margin in the second co-primary endpoint.
