Wave Life Sciences to Present Preclinical Data Supporting Therapeutic Potential of WVE-007 for Obesity at ObesityWeek® 2025

Core Insights - Wave Life Sciences Ltd. presented preclinical data for WVE-007, a GalNAc-siRNA therapeutic aimed at treating obesity by promoting fat loss while preserving muscle mass with infrequent dosing [1][3][12] - The investigational therapy demonstrated significant reductions in Activin E levels, leading to weight loss and improved metabolic health in preclinical models and ongoing clinical trials [1][7][14] Group 1: Preclinical Data and Mechanism - WVE-007 targets INHBE mRNA, which is linked to lower levels of unhealthy visceral fat and reduced risk of type 2 diabetes and cardiovascular disease [2][3] - In preclinical studies, WVE-007 resulted in adipocyte shrinkage, decreased pro-inflammatory macrophages, reduced fibrosis, and enhanced insulin sensitivity in visceral adipose tissue [1][14] - The treatment showed a significant weight loss effect in mice, with no loss of skeletal muscle mass, indicating a healthy weight loss profile [5][14] Group 2: Clinical Trial Progress - The ongoing INLIGHT clinical trial is evaluating WVE-007 in adults with overweight or obesity, focusing on safety, tolerability, and metabolic health [11] - Recent data from the trial showed dose-dependent reductions in Activin E levels, with reductions of up to 85% observed one month after a single dose [7][11] - The treatment was reported to be safe and well-tolerated, leading to the expansion of dosing cohorts in the trial [8][11] Group 3: Future Expectations - Wave Life Sciences anticipates multiple clinical data updates from the INLIGHT trial, including body composition and weight data, starting in Q4 2025 [9] - The company aims to demonstrate the potential for WVE-007 to provide effective obesity treatment with infrequent dosing, potentially only once or twice a year [3][9]
