A secondary analysis of a trial of 2.4mg semaglutide (Wegovy) found nearly half of the teenage participants with obesity returned to normal weight or fell below the obesity threshold. The trial, results of which were published in Obesity, added semaglutide to dietary advice and a daily goal of 60 minutes of moderate- to high-intensity physical activity.
During the 68-week STEP TEENS trial, 44.9% of participants (aged 12–18 with obesity) returned to either normal weight or went down to the overweight category while on treatment compared with only 12.1% of those on placebo. At the end of the trial, 25% of the treatment group dropped to normal weight compared to just 2% for placebo.
“These results underscore the high degree of clinical effectiveness of semaglutide in adolescents with obesity,” said first author Aaron S. Kelly, PhD, in a statement. “In a practical sense, we see that semaglutide reduced weight to a level below what is defined as clinical obesity in nearly 50% of the teens in our trial, which is historically unprecedented with treatments other than bariatric surgery.”
An ‘important piece to the puzzle’ of the obesity problem
“A question I get a lot is, ‘Is this going to solve the obesity problem? Should we just give it to everybody’?” said Kelly, who is at the University of Minesota. “No and no. It’s not going to solve the obesity problem, but it’s an important piece to the puzzle in helping to solve it, especially for those who already have obesity.”
The trial’s initial results saw a an average BMI reduction 16.1% with semaglutide compared with a 0.6% increase with placebo at week 68. On average, participants on semaglutide lost 15.3 kg, while those on placebo gained 2.4 kg.
“The degree of body weight reduction is unprecedented,” lead study author Daniel Weghuber, MD, of Paracelsus Medical University, told MedPage Today at the ObesityWeek meeting, when the results were presented. “After years of frustration, all of a sudden patients were actually losing weight. They’d never seen that before.”
These results led to the approval for ages 12 and older by the FDA in December 2022, after being approved for adults in June 2021. The study also found a slightly superior but non-significant effect in females than males, despite not being set up to measure sex differences. The same was true for ages 12–14 vs 15–18.

Good news for obese patients and hopefully access will be available to all who need it
