Semaglutide leads to substantial, sustained weight loss over 2 years
Overweight (≥1 weight-related comorbidity) or obese adults treated with semaglutide had substantial, sustained weight loss over 104 weeks compared with placebo, according to a study.
In the STEP 5 trial, 304 participants (236 of which were female) were randomly assigned to semaglutide 2.4 mg (n = 152) or placebo (n = 152). Overall, 92.8% completed the trial. All participants had efficacy assessed.
From baseline to week 104, there was a mean body weight change of -15.2% in the semaglutide group compared with -2.6% with placebo group and 77.1% of participants in the semaglutide group achieved weight loss ≥5% compared with 34.4% in the placebo group.
Gastrointestinal adverse events were reported in 82.2% of participants in the semaglutide group compared with 53.9% in the placebo group.
