Ionis Pharmaceuticals, Inc. announced today the initiation of CORE, the second Phase 3 clinical study of olezarsen, formerly known as IONIS-APOCIII-LRx. The CORE study is evaluating olezarsen in people with severe hypertriglyceridemia (triglyceride levels ≥ 500 mg/dL). Severe hypertriglyceridemia is a life-threatening condition associated with high levels of apoC-III and chylomicronemia, which lead to higher rates of acute pancreatitis, higher risk of cardiovascular disease, and has a high morbidity rate.
