NEJM：口服版司美格鲁肽，减肥新选择

Core Viewpoint - The rising global obesity rates are leading to increased risks of diseases such as type 2 diabetes and cardiovascular diseases. GLP-1 class weight loss drugs, particularly Semaglutide, are rapidly gaining popularity and transforming the obesity treatment landscape [2][11]. Group 1: Clinical Study Overview - A clinical study published in the New England Journal of Medicine evaluated the efficacy and safety of oral Semaglutide at a dose of 25 mg for weight management in overweight or obese adults without diabetes over a 71-week period [2][3]. - The study involved 307 participants from 22 centers in Canada, Germany, Poland, and the USA, randomly assigned to receive either oral Semaglutide or a placebo [5]. Group 2: Weight Loss Results - By week 64, participants taking oral Semaglutide experienced an average weight loss of 13.6%, compared to 2.2% in the placebo group, resulting in a difference of 11.4 percentage points [7]. - The proportion of participants achieving weight loss of at least 5% was 79.2% in the Semaglutide group versus 31.1% in the placebo group [7]. Group 3: Cardiovascular and Metabolic Improvements - Oral Semaglutide showed significant advantages in various cardiovascular and metabolic risk factors, including reductions in body weight, waist circumference, and improvements in glycemic control [8]. - Among participants with prediabetes, 71.1% in the Semaglutide group normalized their blood sugar levels by week 64 [8]. Group 4: Safety and Adverse Events - Adverse events were reported in 93.1% of the Semaglutide group compared to 85.3% in the placebo group, with gastrointestinal events being the most common [8]. - The incidence of nausea was 46.6% in the Semaglutide group versus 18.6% in the placebo group, while vomiting rates were 30.9% and 5.9%, respectively [8]. Group 5: Conclusion and Future Implications - The study concluded that a daily oral dose of 25 mg Semaglutide is an effective weight management option for overweight or obese adults and may provide a non-injection alternative for GLP-1 based treatments [11]. - This research lays the groundwork for further formulation testing of this significant weight loss medication, potentially leading to more user-friendly oral tablet forms [11].
