Key Strengths & Strategy (as disclosed to the SEC)
- The FDA also granted Fast Track designation to ulefnersen.   11   Our Innovative Mid-Stage Pipeline of Investigational Medicines   We also have a rich mid-stage pipeline with numerous potentially transformational investigational medicines, including both Ionis-owned and partnered therapies.
- From inception through December 31, 2025, we recognized more than $2.5 billion in total revenue under this collaboration, including more than $2.0 billion in revenue from SPINRAZA royalties and more than $425 million in R&D revenue.   We have exclusively in-licensed patents related to SPINRAZA from Cold Spring Harbor Laboratory and the University of Massachusetts.
- Our technology enables us to change the function or expression of a gene in a highly specific and directed manner, which, in turn, can help address the root cause of a disease.   For example, a gene called TTR contains instructions to make TTR protein, which can accumulate in tissues and cause disease.
- Our technology can also increase or change the expression of a gene.
Partnerships
- PTC is commercializing WAYLIVRA in Brazil and is pursuing access in additional Latin American countries through its exclusive license agreement with us.   WAYLIVRA's conditional marketing authorization in the EU for FCS and approval in Brazil for FCS we re based on efficacy and safety data from the Phase 3 APPROACH study and supported by results from the Phase 3 COMPASS study.
- From inception through December 31, 2025, we have generated more than $420 million in payments under this collaboration.   Biogen   Marketed Medicines   SPINRAZA   In 2012, we entered into a collaboration agreement with Biogen to develop and commercialize SPINRAZA.   We are receiving tiered royalties ranging from 11 percent to 15 percent on sales of SPINRAZA.
