Ionis cuts TRYNGOLZA outlook after slower launch despite Q3 revenue growth

Ionis Pharmaceuticals reported third-quarter 2026 revenue of $243M, up from $157M a year earlier, and a GAAP net loss of $110M. The company reduced 2026 TRYNGOLZA sales guidance to approximately $50M from $100M-$110M, citing a slower launch ramp. It reaffirmed total 2026 revenue guidance of $875M-$900M and highlighted continued growth from DAWNZERA and progress across its pipeline.

The lower TRYNGOLZA outlook reduces near-term expectations for Ionis's newest commercial product, while the unchanged total revenue forecast limits the immediate effect on company-wide guidance. Ionis said the slower launch reflects the time needed to establish a new treatment approach and that it remains confident in the drug's long-term potential.
