ARGX Stock Rises On FDA Approval For Expanded VYVGART Use

The U.S. Food and Drug Administration (FDA) on Friday approved a label expansion for VYVGART (efgartigimod alfa-fcab) and VYVGART Hytrulo (efgartigimod alfa and hyaluronidase-qvfc) for adult patients with generalized myasthenia gravis, a chronic autoimmune neuromuscular disease characterized by fluctuating weakness in skeletal and respiratory muscles.

The approved supplemental Biologics License Application (sBLA) expands VYVGART’s indication to include all serotypes of adult patients living with gMG – anti-AChR-Ab positive, anti-MuSK-Ab positive, anti-LRP4-Ab positive, and triple seronegative.

The FDA’s approval allows VYVGART to be used for all adult gMG patients, enhancing its market potential.

The update follows positive results from the Phase 3 ADAPT SERON study and highlights argenx’s commitment to advancing treatments for autoimmune diseases.

William Blair analyst sees Vyvgart approval in all forms of seronegative patients as the bull case outcome for this PDUFA event and will confer an 18% total addressable expansion in gMG for a franchise annualizing over $5 billion and growing at 64% year-over-year.
