Core Viewpoint - Mazdutide, developed by Innovent Biologics, is a dual receptor agonist targeting GCG and GLP-1, showing promising results in weight loss and liver fat metabolism improvement for obese and overweight adults in China [1][2]. Group 1: Clinical Trial Results - The Phase 3 clinical trial GLORY-1 published in NEJM demonstrated that weekly injections of Mazdutide resulted in significant weight loss and safety in obese or overweight Chinese adults [1]. - In the trial, participants receiving Mazdutide showed a reduction in HbA1c of 1.57% for the 4 mg group and 2.15% for the 6 mg group, compared to a 0.14% reduction in the placebo group [5]. - The weight loss observed was 5.61% for the 4 mg group and 7.81% for the 6 mg group, while the placebo group lost only 1.26% [5]. Group 2: Regulatory Approval - Based on the successful clinical trial results, the National Medical Products Administration (NMPA) approved Mazdutide for long-term weight management in adults with obesity or overweight on June 27, 2025 [2]. Group 3: Additional Research Findings - Two additional Phase 3 studies on Mazdutide for treating type 2 diabetes were published back-to-back in Nature, marking a significant achievement for Chinese drug development in the metabolic and endocrine disease field [2][10]. - In a separate study comparing Mazdutide to Dulaglutide, both doses of Mazdutide showed non-inferiority and superiority in reducing HbA1c compared to Dulaglutide, with treatment differences of -0.24% and -0.30% respectively [9]. - The weight loss was significantly greater in the Mazdutide groups, with differences of -3.78% for the 4 mg group and -5.76% for the 6 mg group compared to Dulaglutide [9].
