Question · Q4 2025
Craig asked about WVE-007's biodistribution to muscles, given it's a liver-directed agent, and how WVE-007's benefit on liver fat would coexist with WVE-008 for PNPLA3 I148M liver disease over longer periods.
Answer
Paul Bolno, President and CEO, clarified that WVE-007 is a GalNAc conjugated siRNA, designed for active receptor-mediated uptake in the liver, making it the target organ for delivery with no expected distribution to muscles. Regarding WVE-008, Erik Ingelsson, Chief Scientific Officer, explained that it directly addresses the PNPLA3 I148M genetic mutation, which drives a broad range of liver diseases beyond just MASH, by correcting the causal variant and restoring enzyme functionality to repair cells and prevent fibrosis. This mechanism is distinct from WVE-007's fat reduction pathway.
