Core Insights - The global weight loss drug market has entered a "dual-target era" with the approval of the first GCG/GLP-1 dual receptor agonist, Mazdutide, by China's National Medical Products Administration (NMPA) [1][6][15] - Novo Nordisk also presented its new GLP-1/insulin receptor dual agonist, Amycretin, at the 85th American Diabetes Association (ADA) Scientific Sessions [4][11] Group 1: Mazdutide - Mazdutide is the first approved GCG/GLP-1 dual receptor agonist, utilizing a unique mechanism to achieve metabolic regulation through dual pathways [8][10] - In the Phase III GLORY-1 study, the 6mg dose group achieved an average weight loss of 14.8% after 48 weeks, with nearly half of the patients losing over 15% of their body weight [9][10] - The drug also significantly improved metabolic indicators, with an 80.24% average reduction in liver fat content (LFC) in the 6mg group, and 77.3% of patients achieving liver fat resolution [10][14] Group 2: Amycretin - Amycretin, developed by Novo Nordisk, is a long-acting GLP-1 and insulin receptor dual agonist that shows significant weight loss effects in clinical trials [11][13] - In the Phase Ib/IIa study, the high-dose group (60mg) achieved an average weight loss of 24.3% after 36 weeks, significantly outperforming existing GLP-1 drugs [13] - The safety profile of Amycretin is favorable, with most adverse reactions being mild to moderate gastrointestinal symptoms, and a low discontinuation rate of less than 5% [13][14] Group 3: Market Implications - The approval of Mazdutide and Amycretin provides safer and more effective treatment options for the approximately 500 million adults in China who are overweight or obese [14] - Despite the presence of 14 other tri-target weight loss drugs in clinical development, Mazdutide and Amycretin are expected to maintain a leading advantage in the next 3-5 years due to their first-in-class status and validated clinical efficacy [14][15] - The competition between these two drugs reflects the growing demand for healthier living among millions of obese patients, indicating a shift towards comprehensive management of metabolic syndromes beyond just weight loss [15]
