Question · Q3 2025
Mike Nedelcovych asked about the LP(a) space, specifically if differences in trial design could salvage pelacarsen's prospects in 2027 if Novartis's Horizon trial fails in 2026. He also inquired if the interesting phase 2 MS data for obexelimab, released after Royalty Pharma's deal announcement, changed their thinking on its peak potential or if MS upside was already considered.
Answer
Marshall Urist, EVP and Head of Research and Investments, stated that if Novartis's Horizon trial fails, differences in trial design and depth of LP(a) lowering could differentiate pelacarsen's outcome, but specific comments are difficult without more details. For obexelimab, he confirmed the MS data validates the mechanism of action, but the near-term funding focus was on IgG4-related disease, which drives the immediate capital need, and MS upside was not the primary driver of the deal.
