Ionis Pharmaceuticals and Sobi have announced the approval of Tryngolza (olezarsen) in the European Union (EU) for adults with familial chylomicronemia syndrome (FCS).\u00a0<\/p>\n

Tryngolza is a ribonucleic acid (RNA)-targeted therapy designed to reduce the production of apoC-III, a protein involved in triglyceride metabolism.\u00a0<\/p>\n It is already approved in the US and is also under evaluation for severe hypertriglyceridemia (sHTG), characterised by fasting triglyceride levels of 500mg\/dL or higher.\u00a0<\/p>\n The EU approval follows a favourable recommendation from the European Medicines Agency\u2019s Committee for Medicinal Products for Human Use (CHMP).\u00a0<\/p>\n Ionis CEO Brett Monia stated: \u201cThe EU approval of Tryngolza is a significant advance for the treatment of FCS.\u00a0<\/p>\n \u201cTryngolza has the potential to be a transformative treatment option for FCS patients in the EU who are at risk of debilitating and life-threatening acute pancreatitis attacks.\u00a0<\/p>\n \u201cWe are proud to work with Sobi, a long-standing partner of Ionis and the FCS community, to make Tryngolza available to people with FCS in the EU.\u201d\u00a0<\/p>\n The EU approval is supported by data from the Phase III Balance trial, which evaluated the efficacy and safety of olezarsen in FCS patients. \u00a0<\/p>\n The therapy showed significant reductions in fasting triglyceride levels at six months and maintained them over a year.\u00a0<\/p>\n It also showed a significant decrease in acute pancreatitis incidents.\u00a0<\/p>\n Results from the study, published in The New England Journal of Medicine, indicated a favourable tolerability and safety profile for Tryngolza.\u00a0<\/p>\n In March 2025, Ionis and Sobi entered a licence agreement<\/a> for the commercialisation of Tryngolza.\u00a0<\/p>\n Sobi holds exclusive rights to market the drug outside the US, Canada and China.\u00a0<\/p>\n \n Sign up for our daily news round-up!
