Novo Nordisk A/SLate-stage STEP Young trial met its primary endpoint, with 40.4% of semaglutide-treated children no longer classified as obese, potentially expanding Wegovy's addressable market.
Novo Nordisk's late-stage STEP Young trial found that 40.4% of children treated with semaglutide, the active ingredient in Wegovy, were no longer classified as having obesity after 68 weeks, compared with none receiving placebo. The trial met its primary endpoint, with semaglutide demonstrating a superior reduction in body mass index at week 68 versus placebo, though all participants also received lifestyle modifications including a reduced-calorie diet and increased physical activity. The result could expand the addressable market for Wegovy, as GLP-1 weight-loss drugs are not currently approved for children under 12 in the U.S., and a study published September 4 in the Pediatrics journal found that GLP-1 prescribing among children ages 8 to 11 with obesity and without diabetes increased roughly 310-fold from 2019 to 2026. The timing is significant as Novo seeks new growth drivers against Eli Lilly; in the REDEFINE 4 trial, Novo's next-generation candidate CagriSema produced 23.0% weight loss after 84 weeks versus 25.5% with Lilly's tirzepatide and failed the primary endpoint of non-inferiority. Hedge funds holding Novo Nordisk increased to 59 in Q2 from 55 in Q1, though positioning was mixed, and short interest rose around 15% to 33.83 million shares as of August 14.

Eli Lilly and CompanyNovo's Wegovy shows promise in pediatric obesity, expanding its market against Lilly, while Lilly's tirzepatide is cited as the comparator that beat CagriSema.
