What is the purpose of this trial?

This trial aims to identify effective and manageable treatments for severe obesity in adolescents. It compares two approaches: an intensive behavioral program with 52 weekly sessions and a combination of medication (semaglutide, a drug used for weight management) with less frequent behavioral sessions. The goal is to determine which method better aids young people in losing weight and maintaining healthy habits. Adolescents aged 12 to 17 with severe obesity, who have not recently used anti-obesity medications, might be suitable candidates for participation. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important findings in obesity management.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you have used anti-obesity medications in the last 6 months.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that intensive programs focusing on healthy eating and exercise for childhood obesity are generally well-received. These programs help children manage their weight through lifestyle changes and typically do not cause harmful side effects.

Semaglutide, a medication used in the trial, has also undergone safety studies. Some studies report that mild stomach issues, such as nausea, are common. In rare cases, more serious problems like gallstones have been noted, and a few participants stopped using it due to side effects. However, doctors have not identified any specific health risks for children using semaglutide. The FDA has already approved the medication for adults with obesity, indicating a certain level of safety.

Overall, both the intensive behavioral program and semaglutide have been researched and demonstrate manageable safety for treating childhood obesity. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for childhood obesity because they offer unique approaches compared to standard options. Traditional treatments often focus solely on lifestyle changes or medication alone. The intensive behavioral program provides 52 weekly sessions that integrate both in-person and virtual support, fostering consistent lifestyle changes over time. Meanwhile, the medication arm combines semaglutide—a medication that regulates appetite—with behavioral therapy, offering a dual-action approach to manage weight. These innovative strategies aim to provide more comprehensive support and potentially better outcomes for children struggling with obesity.

What evidence suggests that this trial's treatments could be effective for childhood obesity?

Research has shown that both intensive behavioral programs and the medication semaglutide, studied in this trial, hold promise for treating childhood obesity. Participants in the Intensive Behavioral Program Arm will receive regular counseling sessions to support lifestyle changes. Studies have demonstrated significant drops in BMI (Body Mass Index) after 12 months, with some improvements persisting over time.

Participants in the Medication Arm will receive semaglutide alongside behavioral therapy. Evidence for semaglutide is strong; one study found that teenagers taking semaglutide lost an average of 9.7 kg, with 73% losing at least 5% of their weight by week 68. This medication controls appetite and food intake, aiding in maintaining a healthy weight. Both treatments provide different but effective ways to manage obesity in young people. ^{2 5 6 7 8}

Orlistat is a safe and effective weight loss medication for adolescents aged 12 to 16, showing significant reductions in body mass index (BMI) in most studies, although it can cause gastrointestinal side effects and lower fat-soluble vitamin levels.

Sibutramine also effectively reduces BMI in overweight adolescents, with reductions up to 5.6 kg/m2, but raises concerns due to potential serious side effects like increased blood pressure and suicidal ideation, necessitating further research.

Both short-stay (2 months) and long-stay (6 months) intensive lifestyle treatments for severely obese children resulted in significant reductions in SDS-BMI after one year, indicating that both approaches are effective.

There were no significant differences in outcomes between the two treatment durations, suggesting that the shorter treatment may be preferable due to its lower burden on children and families.

A pilot study involving 30 adolescents with severe obesity showed that 4 weeks of meal replacement therapy followed by 24 weeks of topiramate did not lead to a significant reduction in BMI compared to a placebo group.

However, the topiramate group experienced notable improvements in visceral fat and cholesterol levels, with no adverse effects on neurocognitive function or bone health, suggesting potential metabolic benefits despite the lack of significant weight loss.

Four new obesity drug therapies approved by the FDA since 2012—lorcaserin, phentermine/topiramate, naltrexone/bupropion, and liraglutide 3.0 mg—can lead to weight loss of about 3 to 9% beyond lifestyle changes after one year.

The effectiveness of these drugs varies among individuals, highlighting the importance of personalized treatment plans that consider the benefits and risks for each patient.

Lifestyle modifications are the first recommended approach for obesity treatment, but achieving long-term weight loss through these methods alone is challenging.

For long-term obesity management, the only FDA-approved medications, sibutramine and orlistat, lead to an additional 3% to 5% weight loss compared to placebo after one year, while bariatric surgery is a viable option for patients with a BMI of 40 or higher, or 35-39.9 with severe obesity-related complications.
