argenx NV ADRPositive Phase 3 myositis data for VYVGART Hytrulo

argenx reported that its ALKIVIA Phase 3 trial of VYVGART Hytrulo in adults with autoimmune myositis met its primary endpoint, with patients showing statistically significant and clinically meaningful improvements in Total Improvement Score over 52 weeks versus placebo and a safety profile consistent with prior studies. This is the first Phase 3 study to show such benefit in immune-mediated necrotizing myopathy, a subtype with no approved targeted therapies, underscoring the potential for VYVGART Hytrulo to address a substantial unmet need across a broad, heterogenous myositis population. The company's narrative projects $9.7 billion revenue and $3.5 billion earnings by 2029, requiring 22.3% yearly revenue growth and about a $1.8 billion earnings increase from $1.7 billion today. Some analysts were already expecting argenx to reach about US$11,000,000,000 in revenue and US$4,500,000,000 in earnings by 2029, so this myositis result may strengthen that more optimistic view or prompt others to reassess how product concentration and future pricing pressure could reshape those forecasts.
