Ionis Pharmaceuticals announced that the FDA has approved TRYNGOLZA (olezarsen) as the first and only treatment indicated to reduce triglycerides and the risk of acute pancreatitis in adults with severe hypertriglyceridemia (sHTG, triglycerides ≥500 mg/dL). The drug is given as a 50 mg or 80 mg once-monthly self-administered autoinjector.
The approval is based on Phase 3 CORE and CORE2 data, where TRYNGOLZA lowered fasting triglycerides by up to 72% versus placebo at six months and sustained reductions at 12 months, reduced acute pancreatitis events by up to 91%, and saw 86% of patients with baseline and 12‑month data reach triglyceride levels below 500 mg/dL. The number needed to treat over one year to prevent one acute pancreatitis episode was 20 in the overall cohort and four in the highest‑risk subgroup. TRYNGOLZA will be available for sHTG in the U.S. in July and represents Ionis’ first independent commercial launch in a prevalent condition.
