CEO Brett Monia said ""

In Tryngolza (olezarsen) for SHTG (severe hypertriglyceridemia) approved by the FDA in June 2026. The Phase 3 CORE data, and from 2 other Phase 3 trials, were positive. Showed pancreatitis reduction. Estimated U.S. sHTG patients over 1 million. Has adjusted price for this much larger population. Tryngolza (olezarsen) peak sales guidance to greater than $3 billion per year. The EU accepted an indication extension application in March. Sales for FCS should benefit from broader access. Changed annual wholesale acquisition price to $40,000, including both FCS and SHTG. About 1 million Americans have high-risk sHTG.

In Q3 2026 the FDA approved Zilganersen for Alexander disease. Licensed outside the US to Recordati.

In Q4 2026 Bepirovirsen for chronic hepatitis B approved by FDA. Partnered with GSK.

Biogen will advance Diranersen (IONIS-MAPTRx / BIIB080), a potential treatment for Alzheimer’s disease, into Phase 3 development.

Dawnzera launch is going well. Largely a switch market. Estimated full year sales of $110 to $120 millon.
