Strategic Initiatives
Growth programs, investments, and their expected impact
Shifting from a historically R&D-focused organization that partnered off assets to a fully integrated commercial-stage biotechnology company independently launching and marketing its own medicines.
Expected impact: Enables Ionis to capture full commercial value from its wholly owned pipeline, targeting over $5 billion in potential annual peak product revenue from owned medicines.
Expanding the market reach of olezarsen from its initial niche indication in familial chylomicronemia syndrome (FCS) under the brand name TRYNGOLZA into the much larger severe hypertriglyceridemia (sHTG) market.
Expected impact: Increases the peak annual net sales guidance for TRYNGOLZA (olezarsen) to over $3 billion for sHTG.
