Mazdutide is the world's first dual GCG/GLP-1 receptor agonist approved for weight loss, offering a unique mechanism that enhances weight-loss efficacy while reducing visceral fat and delivering comprehensive metabolic benefits, named by Fierce Pharma as one of the top ten most anticipated drugs globally in 2025.
The increasing prevalence of overweight and obesity in China poses an urgent public health challenge requiring immediate intervention. In April 2025, the National Health Commission officially included "Healthy Weight Management Action" in the "Healthy China 2030" initiative. Under the updated plan, the national health authorities aim to build supportive environments for effective weight management, raise public awareness and behavior skills, and promote healthy lifestyles to curb rising rates of overweight and obesity. Aligned with these national priorities and the 2025 weight management campaign, the approval of mazdutide represents a timely and important milestone. Aiming to be an innovative leader in the cardiovascular and metabolic (CVM) disease area, Innovent is committed to accelerating the delivery of this drug to benefit a broad population in China.
Scientific and effective treatment options for weight loss are urgently needed in China
Overweight and obesity are chronic metabolic diseases characterized by excessive fat accumulation in the body. The pathogenesis of overweight and obesity includes genetic, metabolic, environmental, and behavioral factors. Obesity can significantly increase the risk of various diseases, such as cardiovascular and cerebrovascular, endocrine, specific tumors, respiratory, reproductive, and skeletal diseases, and can seriously affect quality of life[1]. In China, over 500 million adults live with overweight (BMI ≥ 24 kg/m2 and ˂ 28 kg/m2) or obesity (BMI ≥ 28 kg/m2). Nearly 90% of obese adults have comorbidities, including metabolic dysfunction-associated fatty liver disease, which affects around 50% of adults with overweight and over 80% of adults with obesity. The World Obesity Federation (WOF) estimates that obesity costs China around US$283.3 billion in GDP loss in 2020[2]. With such heavy societal burdens, obesity and related chronic diseases have become major public health concerns in China and around the world.
In response to the escalating obesity problem, several national policies and clinical guidelines have underscored the need for structured outpatient weight management and earlier pharmacological intervention. The National Health Commission's "Notice on Effective Outpatient Settings and Management of Weight Management" encourages the development of optimized outpatient care models. Additionally, "Guidelines for the Diagnosis and Treatment of Obesity (2024 Edition)" recommended pharmacotherapy when lifestyle interventions fail to meet weight loss goals. The "Guidelines for Long-term Weight Management and Clinical Application of Drugs for Obese Patients (2024 Edition)" issued by the Chinese Society of Endocrinology further advocates for initiating drug treatment early in patients with obesity-related comorbidities.
Mazdutide is supported by robust clinical data published in multiple high-impact journals, including Nature, the Lancet sub-journals, and the New England Journal of Medicine. As the first marketed dual GCG/GLP-1 receptor agonist , mazdutide has been recommended by multiple clinical guidelines in China[3],[4],[5],[6] and expert consensus on obesity management on account of its innovative mechanism and solid evidence base.
Multiple metabolic benefits of mazdutide in supporting weight management
GCG receptors are mainly expressed in the liver, and GCG receptor agonism can inhibit hepatic fat synthesis and promote hepatic lipolysis. As a dual GCG/GLP-1 receptor agonist weight loss drug, mazdutide can deliver significant weight loss efficacy and metabolic benefits such as waist circumstance and liver fat content reductions to adults with overweight or obesity.
The approval of mazdutide was mainly based on data from GLORY-1, a Phase 3 pivotal clinical study conducted in Chinese adults with overweight or obesity. The primary endpoint and all key secondary endpoints of the study were successfully achieved in 2024. Results showed that at weeks 32 and 48, the percentage of body weight reduction from baseline and the proportions of participants with a body weight reduction of ≥5%，≥10% and ≥15% in the mazdutide 4 mg group and mazdutide 6 mg group were superior to those of the placebo group.
The results of GLORY-1 study have been presented at the American Diabetes Association (ADA) Annual Meeting and published in the New England Journal of Medicine, which have received widespread attention from industry experts and scholars.
Mazdutide addresses a critical unmet need in China by offering effective treatment for weight reduction while also improving cardiometabolic indicators in adults with overweight or obesity. Its use may help reduce the long-term societal and economic burdens associated with obesity-related diseases.
Professor Linong Ji, the Leading Principal Investigator of GLORY-1, Peking University People's Hospital, stated, "Obesity is a chronic disease that demands a coordinated societal response. With China facing a high prevalence of overweight and obesity, the associated cardiometabolic disease burdens continue to rise. There is an urgent need for weight-loss therapies that are both effective and safe, with proven cardiovascular and metabolic benefits. As the principal investigator of this novel dual GCG/GLP-1 receptor agonist with a unique mechanism of action, I'm proud to see our clinical results recognized by China's national regulatory authority and anticipate its subsequent approval for market launch. My fellow researchers and I hope mazdutide will become a valuable therapeutic option for Chinese adults with overweight or obesity."
Dr. Lei Qian from Innovent Biologics, stated, "Mazdutide represents the next-generation dual GCG/GLP-1 receptor agonist. Its clinical development has been made possible by pooling the collective expertise of leading endocrinology experts across China, and its successful approval reflects the NMPA's high recognition of its clinical value and safety. This milestone marks another breakthrough for Innovent in the cardiovascular and metabolic fields. We hope mazdutide will provide another therapeutic option for Chinese adults with overweight or obesity, improve their quality of life, and alleviate societal burdens. Centered on patient needs and innovation, Innovent has established and will continue to expand its rich CVM pipeline with mazdutide as a cornerstone product, aiming to continuously address the public's growing demand for health and quality of life and to serve more patients."
About Obesity/Overweight:
Obesity is a chronic metabolic disease with complex causes, and it serves as a major risk factor for a range of diseases including diabetes, fatty liver disease, cardiovascular and cerebrovascular diseases, kidney disease, joint disorders, sleep-disordered breathing, and cancer. China has the world's largest population of individuals with overweight or obesity, a trend that is likely to rise[7]. Obesity is associated with multiple comorbidities and is a major contributor to reduced life expectancy and quality of life. In 2019, overweight and obesity accounted for 11.1% of deaths from chronic non-communicable diseases in China, nearly doubling from 5.7% in 1990[8].
Despite the chronic nature of obesity and its need for long-term management, treatment options remain limited. While lifestyle interventions remain the cornerstone of treatment, many patients struggle to achieve or maintain meaningful weight reduction. This underscores the urgent need for safe, effective, and sustainable pharmacological interventions.
About Mazdutide:
Innovent entered into an exclusive license agreement with Eli Lilly and Company (Lilly) for the development and potential commercialization of mazdutide, a dual GCG /GLP-1 receptor agonist, in China. As a mammalian oxyntomodulin (OXM) analogue, in addition to the effects of GLP-1 receptor agonists on promoting insulin secretion, lowering blood glucose and reducing body weight, mazdutide may also increase energy expenditure and improve hepatic fat metabolism through the activation of glucagon receptor. Mazdutide has demonstrated excellent weight loss and glucose-lowering effects in clinical studies, as well as reducing waist circumference, blood lipids, blood pressure, serum uric acid, liver enzymes, liver fat content and improved insulin sensitivity.
Mazdutide is approved by NMPA for chronic weight management in adults with overweight or obesity*; and mazdutide currently has another NDA accepted for review by NMPA, for glycemia control in adults with type 2 diabetes.
