James Gordon's questions to argenx SE (ARGX) leadership • Q2 2025
Question
James Gordon from JPMorgan Chase & Co. asked about the CIDP launch dynamics, questioning if Vyvgart use is expanding into IVIG-naive patients beyond the initial target population, and also inquired about the future outlook for gross margin given cost reduction efforts and royalty payments.
Answer
CFO Karl Gubitz projected the gross margin to remain around 11%, as reduced manufacturing costs from scaling up are expected to be offset by increasing royalty payments to Halozyme as the subcutaneous formulation's share grows. COO Karen Massey added that 85-90% of CIDP patients are still IVIG switches, consistent with the initial strategy, and that expanding to earlier lines of treatment will depend on securing payer access over time.
