What believers are saying

  • May 8, 2026 FDA approval opened VYVGART to all adult gMG serotypes.
  • August 17, 2026 ALKIVIA met primary endpoint in autoimmune myositis, adding a multibillion-dollar indication.
  • September 29, 2026 AANEM data extended VYVGART into ocular MG and longer-duration CIDP use.

What critics are saying

  • UCB's RYSTIGGO and J&J's nipocalimab attack the same FcRn market by 2027.
  • VYVGART concentration remains extreme; one franchise drove $2.8 billion first-half 2026 sales.
  • If ALKIVIA or upcoming myositis filings disappoint, argenx loses its next blockbuster expansion.

What makes argenx unique

  • VYVGART is first-and-only approved for all adult gMG serotypes after May 8, 2026.
  • argenx scaled $1.5 billion Q2 2026 product sales with 60% year-over-year growth.
  • August 27, 2026 Forte acquisition added FB102, broadening the immunology pipeline.

Argenx shares drop 15% as Vyvgart fails Sjögren's trial despite celiac drug success

Argenx shares dropped 15% on Thursday after the Dutch biotech announced its blockbuster drug Vyvgart failed to help patients with Sjögren's disease. An independent monitoring board recommended ending the Phase 3 study "for futility" following an interim analysis. The timing surprised analysts, who weren't expecting results until the second half of 2027. Success in Sjögren's could have generated up to $1.4 billion in peak sales for that indication alone. A separate announcement of successful Phase 2 research into a celiac disease drug failed to offset investor concerns. Argenx acquired the medicine, FB102, through a $2.2 billion takeover of Forte Biosciences this year. TD Securities analyst Yaron Werber models $988 million in peak sales for the celiac drug. Despite the setback, Argenx maintains a market cap of around $50 billion. Vyvgart sales reached $1.5 billion in the second quarter alone.

Argenx, a biopharmaceutical company with a market capitalisation near $60 billion, has caught the attention of Wall Street analysts. Ten analysts predict the biotech stock will reach at least $1,200 over the next 12 months, up from around $919 as of 2 October 2026. Wells Fargo and UBS set the highest price targets at $1,415 and $1,400 respectively, representing potential gains exceeding 50%. The average price target amongst 21 analysts stands at approximately $1,182, suggesting 29% upside. All but one analyst recommends buying the stock. Argenx's optimism stems from strong performance, delivering $1.5 billion in global product net sales last quarter, up 60% year over year. Its flagship drugs Vyvgart and Vyvgart Hytrulo drive growth, with additional approvals for autoimmune diseases potentially forthcoming.

argenx to Present New VYVGART Data in MG and CIDP, Plus Pipeline Results, at AANEM 2026.

argenx to Present New VYVGART Data in MG and CIDP, Plus Pipeline Results, at AANEM 2026. 09/30/2026 Key Takeaways * argenx will present data on its portfolio and pipeline at the AANEM Annual Meeting and the MGFA Scientific Session, September 29 to October 2 in Orlando, Florida, including four oral presentations and dozens of posters. * New VYVGART (efgartigimod) results include deepening improvement in ocular myasthenia gravis (MG), sustained one-year efficacy in anti-AChR antibody-negative generalized MG (gMG), real-world data on earlier treatment, and long-term and switch data in chronic inflammatory demyelinating polyneuropathy (CIDP). * argenx will also present Phase 2 empasiprubart data in multifocal motor neuropathy (MMN) and Phase 1b adimanebart data in DOK7 congenital myasthenic syndrome (CMS). argenx, an Amsterdam-based immunology company, announced it will present clinical, long-term, and real-world data for VYVGART (intravenous efgartigimod alfa-fcab) and VYVGART Hytrulo (subcutaneous efgartigimod alfa and hyaluronidase-qvfc), along with results for two pipeline candidates. Chief Medical Officer Luc Truyen, M.D., Ph.D., said the data show how far the evidence for VYVGART reaches, across years of treatment and into patient populations historically left out of clinical trials. In MG, the company will present three sets of findings: * Ocular MG. In the Phase 3 ADAPT OCULUS study, patient-reported ocular scores on the Myasthenia Gravis Impairment Index (MGII) improved further after two VYVGART cycles beyond the placebo-controlled period. Scores went from -4.5 to -6.8 points in patients with anti-AChR antibodies and from -2.7 to -4.5 points in triple-seronegative patients. The company says the results build on evidence for VYVGART's potential as the first targeted treatment for ocular MG.
