Ionis Pharmaceuticals Inc Q3 2021 Earnings Call Summary

The following is excerpted from the question-and-answer section of the transcript.

Question: Gary Jay Nachman - BMO Capital Markets Equity Research - Analyst : So first on eplontersen for TTR-PN. Depending on the data in the Phase III mid next year, how do you expect it will be used in that market? How much could it potentially expand addressable patients relative to TEGSEDI? And how will you promote it? Will you rebuild your infrastructure there? And then on SPINRAZA, just how long do you think it will take for Biogen to run the ASCEND study? Is that something that could potentially update the label? And are physicians currently using higher dosing on their own for risky failures to the extent that you're aware of that?

Question: Jessica Macomber Fye - JPMorgan Chase & Co, Research Division - Analyst : Just 2. First, how should we interpret the IGF-1 AUC data for cimdelirsen in acromegaly. Can you talk about how these patients IGF-1 levels looked relative to the upper limit of normal after treatment? And then on PCSK9, thinking beyond the subcu version to an oral. Are you still eager to pursue that path? Or is it still too early to say? And assuming you'll eventually need an outcome study for either agent, would you envision ultimately developing both subcu and oral in parallel or choose one over the other?
