Abstract

BACKGROUND: A once-weekly, 2.4-mg dose of subcutaneous semaglutide, a glucagon-like peptide-1 receptor agonist, is used to treat obesity in adults, but assessment of the drug in adolescents has been lacking. METHODS: In this double-blind, parallel-group, randomized, placebo-controlled trial, we enrolled adolescents (12 to <18 years of age) with obesity (a body-mass index [BMI] in the 95th percentile or higher) or with overweight (a BMI in the 85th percentile or higher) and at least one weight-related coexisting condition. Participants were randomly assigned in a 2:1 ratio to receive once-weekly subcutaneous semaglutide (at a dose of 2.4 mg) or placebo for 68 weeks, plus lifestyle intervention. The primary end point was the percentage change in BMI from baseline to week 68; the secondary confirmatory end point was weight loss of at least 5% at week 68. RESULTS: A total of 201 participants underwent randomization, and 180 (90%) completed treatment. All but one of the participants had obesity. The mean change in BMI from baseline to week 68 was -16.1% with semaglutide and 0.6% with placebo (estimated difference, -16.7 percentage points; 95% confidence interval [CI], -20.3 to -13.2; P<0.001). At week 68, a total of 95 of 131 participants (73%) in the semaglutide group had weight loss of 5% or more, as compared with 11 of 62 participants (18%) in the placebo group (estimated odds ratio, 14.0; 95% CI, 6.3 to 31.0; P<0.001). Reductions in body weight and improvement with respect to cardiometabolic risk factors (waist circumference and levels of glycated hemoglobin, lipids [except high-density lipoprotein cholesterol], and alanine aminotransferase) were greater with semaglutide than with placebo. The incidence of gastrointestinal adverse events was greater with semaglutide than with placebo (62% vs. 42%). Five participants (4%) in the semaglutide group and no participants in the placebo group had cholelithiasis. Serious adverse events were reported in 15 of 133 participants (11%) in the semaglutide group and in 6 of 67 participants (9%) in the placebo group. CONCLUSIONS: Among adolescents with obesity, once-weekly treatment with a 2.4-mg dose of semaglutide plus lifestyle intervention resulted in a greater reduction in BMI than lifestyle intervention alone.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Semaglutide 2.4 mg is approved by FDA/EMA from age 12.

    “Approved by FDA/EMA from age 12.”

    From Precision obesity medicine: A phenotype-guided framework for pharmacologic therapy across the lifespan (2025) · cites this paper as [113]

    The paper’s introductory passage in the Abstract > Conclusions section says that, for adolescents aged 12 or older, the FDA had approved liraglutide, orlistat, and phentermine–topiramate, while the EMA had approved only liraglutide. It describes semaglutide 2.4 mg as approved for adults, not adolescents. No page numbers are available in our copy. (LLM, conf=0.89)

    Checked by a reasoning model — may be wrong.

  • In STEP TEENS, 73% achieved ≥5% weight loss and there was significant amelioration of CVD factors (e.g., waist circumference, ALT, HbA1c) and no adverse impact on pubertal development and bone health.

    “73% achieved ≥ 5% weight loss and with significant amelioration of CVD factors (e.g. waist circumference, ALT and HbA1c) and no adverse impact on pubertal development and bone health [113].”

    From Precision obesity medicine: A phenotype-guided framework for pharmacologic therapy across the lifespan (2025) · cites this paper as [113]

    The Results (Efficacy Outcomes) report that 73% of the semaglutide group lost at least 5% of body weight and that waist circumference, glycated hemoglobin, and ALT were lower than with placebo at week 68. The Results (Safety) and Discussion report no apparent effect on pubertal development during the trial. Our copy does not report an assessment of bone health, so it does not support that part of the claim. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Similar efficacy to that in adults was achieved with once-weekly subcutaneous injections of 2.4 mg semaglutide in the STEP Teens trial among adolescents aged 12-18 years.

    “Similar efficacy was achieved with once-weekly subcutaneous injections of 2.4 mg semaglutide in the STEP Teens trial among adolescents aged 12–18 years [80]”
  • In the STEP TEENS trial, adolescents achieved a −16.1% mean BMI reduction vs +0.6% in the placebo group.

    “In the STEP TEENS trial, adolescents achieved a − 16.1% mean BMI reduction vs. + 0.6% in the placebo group.”
  • Similar efficacy to 2.4 mg once weekly injected semaglutide was achieved in adolescents with comorbidities (STEP Teens) and with a high dose (50 mg once daily) of the oral formulation of semaglutide in adults (OASIS-1).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
