Plozasiran in patients with severe hypertriglyceridaemia: 12-month results
Presenting authorGerald WattsGeneral / Preventive / Lipids · The University of Western AustraliaGerald F. Watts is Winthrop Professor of Cardiometabolic and Internal Medicine in the UWA Medical School at the University of Western Australia and a Senior Consultant Physician in the Department of Cardiology at Royal Perth Hospital, where he leads the Cardiometabolic Service and Lipid Disorders Clinic. He trained at Imperial College and King’s College, University of London, and chairs the Familial Hypercholesterolaemia Australasia Network. His research focuses on lipidology, lipoprotein metabolism, familial hypercholesterolaemia, and models of care for high-risk dyslipidaemias.
Twelve-month plozasiran outcomes in severe hypertriglyceridaemia remain pending; this leaves open questions on long-term efficacy and cardiovascular benefit.
Key result
Plozasiran 12-month clinical outcomes in patients with severe hypertriglyceridaemia are currently pending presentation at the ESC Congress 2026.
Expert reaction lands here the moment SHASTA-3/4 reports.
The Phase 3 SHASTA-3 and SHASTA-4 trials of plozasiran (an APOC3-targeting siRNA) in ~750 adults with severe hypertriglyceridemia showed median triglyceride reductions of 79% and 81% at 12 months versus ~27% with placebo, with a statistically significant 78% reduction in acute pancreatitis events (100% in highest-risk patients). The results position plozasiran as a direct competitor to Ionis's olezarsen (Tryngolza), with quarterly dosing and a clean liver safety profile as potential differentiators. Coverage is predominantly from the sponsor's press release, with limited independent expert commentary available before the ESC Congress late-breaker presentation on August 30, 2026.
