Groups Question FDA Weight Loss Paper
The Obesity Action Coalition and American Society for Metabolic and Bariatric Surgery say an FDA discussion paper on benefit/risk approaches for weight loss medical devices may not recognize that treating the chronic disease of obesity requires a full continuum of care. The groups’ comment letter says that discussion paper use of language quantifying weight loss treatment as short-term or long-term when applied to devices might not reflect real-world care. The groups also say the agency should consider using a staging system to differentiate care for those who are well versus those who are sick.
In their letter, the Association for Bariatric Endoscopy, the American College of Gastroenterology, the American Gastroenterological Association, and the American Society for Gastrointestinal Endoscopy say a statement in the discussion paper could be interpreted to mean that FDA will require sponsors to perform randomized controlled trials with a sham control arm when this is possible. “Comparing open-label and sham-controlled studies with the same categorization scheme is problematic,” the groups say. They recommend that the proposed benefit categorization should only be used if all future studies are open-label.
