Seoul, South Korea – In a groundbreaking development for the treatment of obesity in East Asia, a new clinical trial led by researchers at Bundang Seoul National University Hospital has demonstrated the significant efficacy of Semaglutide in patients with a Body Mass Index (BMI) of 25 or higher. Published today in the prestigious Lancet Diabetes & Endocrinology, the study reveals an average weight reduction of 16.0% and a substantial 11.9cm decrease in waist circumference – results that could reshape medical guidelines and insurance coverage across the region.
First-of-Its-Kind Trial Targets East Asian Obesity Standards
What sets this research apart is its focus on East Asian obesity standards. Traditionally, obesity treatment has largely been based on Western BMI thresholds. This study is the first randomized controlled trial to specifically apply the BMI 25kg/㎡ criterion, more commonly used to define obesity in East Asian populations, where genetic and metabolic factors can differ significantly. This is a critical step towards personalized medicine and more effective treatment strategies.
The three-phase (3B) clinical trial, conducted across 12 institutions in Korea and Thailand, involved 150 non-diabetic patients. Participants were divided into groups receiving Semaglutide or a placebo, alongside lifestyle controls, for a period of 44 weeks. The results were striking: the Semaglutide group experienced a 16.0% average weight loss compared to just 3.1% in the placebo group. Furthermore, over 53% of those on Semaglutide achieved a weight loss of more than 15%, a rate approximately 12 times higher than the placebo group.
Beyond Weight Loss: Improving Abdominal Obesity and Safety Profile
The benefits extended beyond overall weight reduction. The 11.9cm reduction in waist circumference demonstrates a significant improvement in abdominal obesity, a key risk factor for cardiovascular disease, type 2 diabetes, and other health complications. This is particularly important in East Asian populations, who are predisposed to visceral fat accumulation.
Addressing concerns about side effects, the study found that 89.1% of the Semaglutide group experienced gastrointestinal symptoms like nausea, constipation, and diarrhea. However, a comparable 77.6% of the placebo group also reported these issues, suggesting the side effects weren’t significantly different between the two groups. Professor Lim Soo-sang, the lead researcher, emphasized that these adverse reactions are typical of GLP-1 receptor agonists and generally manageable.
Semaglutide: A Deeper Dive into the Science and Future Implications
Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, originally developed for the treatment of type 2 diabetes. GLP-1s work by mimicking the effects of the naturally occurring GLP-1 hormone, which regulates appetite and blood sugar levels. Its effectiveness in promoting weight loss has led to its increasing use – and now, stronger evidence for its efficacy – in obesity management.
Professor Lim, who also led a prior 3A clinical trial in 2022 paving the way for Semaglutide’s introduction to Korea, believes this latest research will be instrumental in shaping future medical guidelines and insurance policies. “This study provides a robust foundation for incorporating Semaglutide as a viable treatment option for East Asian patients diagnosed with obesity, even at relatively lower BMI levels,” he stated. The findings open the door for broader access to this potentially life-changing medication.
The implications of this study extend beyond individual patient care. As obesity rates continue to rise globally, particularly in Asia, effective and culturally-sensitive treatment strategies are urgently needed. Semaglutide, backed by this rigorous research, represents a significant step forward in addressing this growing public health challenge.
