(Nasdaq: WVE), a clinical-stage biotechnology company focused on unlocking the broad potential of RNA medicines to transform human health, today announced positive interim data from the lowest therapeutic cohort of the ongoing first-in-human INLIGHT trial evaluating WVE-007, an investigational INHBE GalNAc-siRNA using Wave’s proprietary SpiNA design, for the treatment of obesity. In this interim assessment, a single 240 mg dose of WVE-007 led to an improvement in body composition characterized by reductions in total and visceral fat mass at three months and an increase in lean mass. There was also a favorable safety profile as well as durable reductions in serum Activin E that support potential once or twice-yearly dosing. These results add to a growing body of data supporting the silencing of INHBE and its downstream protein product (Activin E) as a therapeutic approach to obesity with strong evidence from human genetics. Individuals who have a protective loss-of-function variant in one copy of the INHBE gene have a healthier body composition and cardiometabolic profile, inc...
