▎Mazdutide Research
What is the research background of Mazdutide?
The prominent issue of global obesity and related diseases:
Overweight and obesity have become increasingly severe global public health challenges. According to the World Obesity Atlas, the number of obese people globally reached 764 million in 2020 and is expected to rise to 1 billion by 2030. Obesity can trigger numerous health complications, such as cardiovascular diseases and type 2 diabetes, which seriously affect the individual's quality of life and global medical resources. This has driven researchers to explore effective treatment methods, especially new drugs.
The development foundation of incretin-based drugs:
Since the concept of incretin was proposed in 1932, related research has been steadily advancing. In 1987, GLP-1 was identified as a key regulator of insulin secretion in the pancreas, and treatment regimens for type 2 diabetes based on incretin were developed. In 2005, exenatide, the world's first GLP-1 receptor agonist (GLP-1RA), was approved for marketing, laying a solid theoretical and practical foundation for the research and development of new incretin-based drugs like Mazdutide. Mazdutide is an analog of mammalian oxyntomodulin (OXM). As a new-generation dual agonist targeting GLP-1R and GCGR, it has a unique dual-action mechanism and broad prospects in the treatment of weight loss and related diseases.
What is the mechanism of action of Mazdutide?
Agonistic effect on the glucagon-like peptide-1 (GLP-1) receptor:
GLP-1 is an intestinal hormone that can promote insulin secretion and inhibit glucagon secretion in a glucose concentration-dependent manner, thereby reducing blood glucose levels [1]. As a GLP-1 receptor agonist, Mazdutide mimics the action of GLP-1, enhancing insulin secretion and reducing glucagon release, which helps regulate blood glucose. Moreover, GLP-1 receptor agonists can delay gastric emptying, enhance satiety, and reduce food intake, which is beneficial for weight control [1, 2].
Agonistic effect on the glucagon receptor:
Glucagon can promote the breakdown of liver glycogen and gluconeogenesis, leading to an increase in blood glucose. Mazdutide, by activating the glucagon receptor, can regulate multiple aspects of glucose metabolism, achieving fine regulation of blood glucose. Glucagon also promotes lipolysis, helping to reduce fat accumulation and lower body weight [1, 2].
Regulatory effect on blood pressure:
Mazdutide can reduce both systolic and diastolic blood pressure. On the one hand, it lowers blood pressure by regulating glucose and lipid metabolism and improving vascular endothelial function; on the other hand, it may affect blood pressure regulation mechanisms such as the renin-angiotensin system.
What is the specific mechanism of Mazdutide for weight loss?
Regulation of blood glucose and metabolism:
As a dual agonist of the glucagon-like peptide-1 (GLP-1) and glucagon receptors, one of the multiple physiological effects of GLP-1 is to regulate blood glucose levels. It promotes insulin secretion, inhibits glucagon secretion, reduces blood glucose[1], delays gastric emptying, increases satiety, and reduces food intake. Glucagon, on the other hand, promotes lipolysis and energy consumption. Therefore, Mazdutide activates both receptors and regulates blood glucose metabolism to achieve weight loss. Studies have shown that Mazdutide can reduce body weight, blood pressure (systolic and diastolic), total cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein levels[3], indicating that it can lead to weight loss and improve obesity-related metabolic disorders.
Influence on appetite and energy intake:
Mazdutide may achieve weight loss by influencing appetite and energy intake. In some clinical trials, participants experienced gastrointestinal reactions such as decreased appetite after using Mazdutide[3]. This may be caused by the direct action of Mazdutide on the gastrointestinal tract or through regulation by the central nervous system. Regardless of the mechanism, decreased appetite and gastrointestinal side effects will reduce energy intake and promote weight loss. In addition, Mazdutide may affect appetite by regulating neurotransmitters and hormones in the brain. For example, GLP-1 can act on the hypothalamus to regulate appetite and energy balance[4].
What are the specific action pathways of Mazdutide in regulating blood glucose?
Stimulation of insulin secretion:
Glucagon-like peptide-1 (GLP-1) receptor agonists can stimulate insulin secretion. As a dual agonist of GLP-1 and glucagon receptors, Mazdutide may activate the GLP-1 receptor to prompt pancreatic islet β cells to secrete insulin. Insulin is a key hormone for reducing blood glucose, which can promote cells to take up glucose and lower blood glucose levels[1].
Inhibition of glucagon secretion:
At the same time, Mazdutide may act on the glucagon receptor to inhibit glucagon secretion. Glucagon and insulin are antagonistic to each other in blood glucose regulation, and reducing its secretion is conducive to lowering blood glucose[1].
Regulation of glucose metabolism:
Mazdutide may regulate glucose metabolism at multiple levels to exert its hypoglycemic effect, such as affecting the glucose metabolism in the liver, muscle, and adipose tissues. In the liver, it reduces the breakdown of liver glycogen and gluconeogenesis, decreasing the production of blood glucose; in muscle tissue, it promotes the uptake and utilization of glucose; in adipose tissue, it regulates lipid metabolism, reduces the release of free fatty acids, and indirectly affects blood glucose[1, 3].
Influence on appetite and energy intake:
Studies have found that Mazdutide can reduce appetite and energy intake, possibly by acting on receptors in the central nervous system and regulating the appetite signaling pathway. Reducing food intake can lower the source of blood glucose and help control blood glucose levels[3, 5].

What are the applications of Mazdutide?
Treatment of type 2 diabetes:
A randomized, double-blind, placebo-controlled Phase 2 trial showed that Mazdutide, a weekly-administered dual agonist of glucagon-like peptide 1 (GLP-1) and glucagon receptors, demonstrated good efficacy and safety in Chinese patients with type 2 diabetes[1].
Application in weight loss:
Research on patients with and without diabetes: A systematic review and meta-analysis showed that Mazdutide can effectively reduce the body weight of adults with or without diabetes[3]. The research included seven randomized controlled trials with a total of 680 participants. The results showed that compared with the placebo, Mazdutide led to a more significant reduction in body weight (mean difference [MD] = -6.22%, 95% confidence interval [CI]: -8.02% to -4.41%, I² = 90.0%) (Nalisa D L, 2024). Subgroup and meta-regression analyses found that patients without diabetes had more significant weight loss, and patients treated for 24 weeks had more prominent weight reduction compared to those treated for 12 - 20 weeks[3].
Application in Chinese adults with overweight or obesity:
A mid-term analysis of a randomized, two-part (low dose up to 6mg and high dose 9mg), double-blind, placebo-controlled Phase 2 trial conducted in Chinese adults with overweight or obesity showed that Mazdutide was safe and effective in this population during the 24-week treatment period, bringing about significant and clinically meaningful weight loss [2]. In the study, adults with overweight (BMI ≥ 24 kg/m²) accompanied by hyperphagia and/or at least one obesity-related comorbidity, or adults with obesity (BMI ≥ 28 kg/m²) were randomly assigned to receive weekly Mazdutide at doses of 3mg, 4.5mg, 6mg or a matching placebo. The results showed that from the baseline to the 24th week, the mean percentage change in body weight was -6.7% (standard error 0.7) in the 3mg Mazdutide group, -10.4% (0.7) in the 4.5mg group, -11.3% (0.7) in the 6mg group, and 1.0% (0.7) in the placebo group. Compared with the placebo, the treatment difference ranged from -7.7% to -12.3% (all p < 0.0001) [2].
In conclusion, as an innovative dual-target agonist, through multiple mechanisms such as regulating blood glucose, promoting fat metabolism, and inhibiting appetite, Mazdutide can effectively improve the blood glucose levels of patients with type 2 diabetes and help obese people lose weight. It injects new vitality into the treatment of metabolic diseases and is expected to alleviate the global burden of obesity and related diseases.
