25 June 2026

US biotech Ionis Pharmaceuticals (Nasdaq: IONS) yesterday announced that the US Food and Drug Administration (FDA) has approved Tryngolza (olezarsen) as an adjunct to diet to reduce triglycerides (TG) and the risk of acute pancreatitis in adults with severe hypertriglyceridemia (sHTG: TG greater than or equal to 500mg/dL).

Tryngolza is available in a 50mg or 80mg dose and is self-administered once monthly via an autoinjector. sHTG is characterized by an increased risk of acute pancreatitis, which causes debilitating abdominal pain that often leads to repeated and prolonged hospitalization, permanent organ damage and can be life-threatening.
