Question · Q3 2025
Terence Flynn asked about the AMVUTTRA deal, specifically what differences exist in the current transaction compared to Blackstone's original 2020 deal with Alnylam. He also sought Royalty Pharma's views on the implications for the probability of success of Amgen's olpasiran phase III study, given Amgen's recent report of a slower-than-expected event rate.
Answer
Pablo Legorreta, CEO and Chairman, clarified that the 2020 Blackstone deal was larger and primarily related to Inclisiran, with the 1% AMVUTTRA royalty being a smaller add-on. He highlighted Royalty Pharma's unique perpetual business model, allowing them to hold long-term assets to maturity, unlike closed-end funds, and their differentiated view on AMVUTTRA's sales trajectory and duration. Marshall Urist, EVP Head of Research and Investments, noted that the slower event rate for olpasiran was not surprising given Novartis's similar observation, and while it introduces timing uncertainty, it doesn't change their view on the probability of success for the LP(a) class.
