Characterize Obesity as a Chronic Disease: Lilly
Eli Lilly, which recently obtained FDA approval for its Zepbound (tirzepatide) as a weight-loss drug, says that as the agency revises its 2007 guidance on developing products for weight management it should clearly state that obesity is a complex, chronic disease. In a comment letter, Lilly says such a characterization should be reflected in approved product labeling.
The company also calls on FDA to “incorporate the most recent scientific understanding of obesity into the revised draft guidance.” In particular, it says the agency should consider whether Body Mass Index alone is a reliable and equitable indicator of obesity. Lilly recommends that in addition to overall weight reduction, new clinical endpoints that include measures of adiposity are needed for future clinical trials of weight loss products
The company calls for a prompt revision of the guidance “in a manner that reflects the evolving view of obesity as a disease, provides updated recommendations for industry on appropriate criteria for identifying patients with obesity for inclusion in clinical trials, and addresses the need for new measures of effectiveness that can adequately support the development of new treatments for obesity.”
