Peter Lawson's questions to Karyopharm Therapeutics (KPTI) leadership • Q2 2025
Question
Peter Lawson of Barclays Capital inquired about the key drivers for XPOVIO revenue in the quarter, specifically the contribution from volume, pricing, and inventory. He also asked about the company's confidence that the encouraging blinded safety data for myelofibrosis will hold up once unblinded.
Answer
CEO Richard Paulson noted that inventory was relatively consistent and that revenue drivers were a balance of consistent demand and an improved gross-to-net percentage following a one-time returns issue in the prior quarter. Chief Medical Officer Reshma Rangwala expressed confidence in the blinded safety data trends, noting that multiple snapshots over time have shown a consistent and favorable evolution compared to stable historical data for ruxolitinib monotherapy, which strengthens the extrapolation.
