Arrowhead Pharmaceuticals, Inc. (NASDAQ:ARWR) today announced results from the Phase 3 PALISADE study of investigational plozasiran in patients with familial chylomicronemia syndrome (FCS), a severe and rare genetic disease which currently has no approved treatments in the U.S. PALISADE successfully met its primary endpoint and all multiplicity-controlled key secondary endpoints, including statistically significant reductions in triglycerides (TGs), apolipoprotein C-III (APOC3), and the incidence of acute pancreatitis (AP). These data were presented today in a late-breaking oral presentation at the European Society of Cardiology (ESC) Congress 2024 and simultaneously published in The New England Journal of Medicine.

Based on these positive findings from the PALISADE study, Arrowhead intends to file a New Drug Application with the United States Food and Drug Administration (FDA) by year-end 2024 and plans to seek regulatory approval with additional global regulatory authorities thereafter.
