PRESS RELEASE

Key Weight Loss and Safety Data Presented for the Obalon Swallowable Gas-Filled Balloon System at the 35th ASMBS Annual Meeting at Obesity Week 2018

Clinical results presented from over 1,300 patients treated at 108 sites with Obalon’s non-surgical weight loss solution in commercial setting

SAN DIEGO, Nov. 15, 2018 (GLOBE NEWSWIRE) -- Obalon Therapeutics, Inc. (NASDAQ:OBLN), a vertically integrated medical technology company with the first and only FDA-approved swallowable, gas-filled intragastric balloon system for the treatment of obesity, announces that clinical data from a large-scale commercial use study was presented at the American Society for Metabolic and Bariatric Surgery (ASMBS) Annual Meeting at Obesity Week 2018 by Rachel Moore, M.D., Bariatric Surgeon and Weight Loss Specialist. The presentation of the 1,300+ patient data set titled, The First Year of Commercial Experience with a Swallowable, Gas-filled, 3- Balloon System, demonstrates the real-world utility of the Obalon Balloon System, with weight loss and safety results from 108 treatment sites in the United States.

Average weight loss data on patients receiving three balloons and six months of therapy was 21.7 pounds, resulting in a 9.9% reduction in total body weight and a 3.5 point decrease in BMI compared to baseline values.  Of note, the top quartile of those patients lost an average of 39 pounds, resulting in a 16.8% reduction in total body weight and a 6.2 point decrease in BMI compared to baseline values. Consistent with prior controlled clinical trial results, the rate of serious adverse events (SAEs) reported was 0.14%, with SAEs occurring in two of the 1,343 patients evaluated for safety. No deaths were reported. Non-serious adverse events occurred in 14.3% of patients, also consistent with prior controlled clinical trial results.

88% of patients treated received three balloons and achieved weight loss that was statistically higher than patients receiving only one or two balloons. 82% of patients completed all six months of therapy and 97% completed at least three months of therapy.

“This large real-world data set validates the Obalon Balloon System as an important tool for battling the obesity epidemic,” said Dr. Moore. “The clinically meaningful weight loss and excellent safety profile can provide clinicians and patients with an important weight loss option for patients who may not qualify for or will not consider bariatric surgery.”
