速递｜与司美格鲁肽相当！Wave公布siRNA药物临床前数据，展示其治疗肥胖和代谢疾病的潜力

Core Viewpoint - Wave Life Sciences Ltd. presents promising preclinical data for its candidate drug WVE-007, which targets INHBE mRNA to reduce fat mass without compromising muscle quality, potentially lowering the risk of metabolic diseases such as type 2 diabetes and coronary artery disease [1][7]. Group 1: Mechanism and Efficacy - WVE-007 is a GalNAc-modified siRNA that significantly downregulates INHBE mRNA and its product Activin E protein, which inhibits fat breakdown in obesity [2]. - A single administration of WVE-007 results in weight loss comparable to the widely used GLP-1 receptor agonist semaglutide [3]. - The drug effectively reduces visceral fat, decreases adipocyte size, and preserves muscle mass, supporting weight loss through the restoration of adipose tissue function [4]. Group 2: Inflammatory Response - WVE-007 significantly inhibits the recruitment of pro-inflammatory M1 macrophages while maintaining levels of anti-inflammatory M2 macrophages, demonstrating strong anti-inflammatory potential [5]. Group 3: Combination and Maintenance Therapy - When used in conjunction with semaglutide, INHBE-siRNA can double the weight loss effect, indicating a synergistic therapeutic potential [6]. - After discontinuation of semaglutide, INHBE-siRNA significantly slows weight regain, suggesting it could serve as a maintenance or transitional therapy for GLP-1 treatments [7]. Group 4: Genetic Insights and Future Prospects - Individuals carrying INHBE gene loss-of-function variants often exhibit healthier metabolic profiles, including reduced abdominal fat, lower triglyceride levels, and decreased risks of type 2 diabetes and cardiovascular diseases [7]. - The Chief Scientific Officer of Wave emphasizes that if clinical trials confirm these mechanisms, WVE-007 could revolutionize obesity treatment by offering a new pathway that requires only one to two injections per year for healthy weight loss while preserving muscle mass [7].
