Argenx stock dives by a third after late-stage trial didn't meet goals

Argenx stock (BE:ARGX) (ARGX) lost a third of its value as the Amsterdam biotech said a late-stage trial did not meet primary or secondary endpoints. The Phase 3 study was of using efgartigimod subcutaneous in adults with pemphigus vulgaris and pemphigus foliaceus. The company said it will not pursue additional development in pemphigus and plans to prioritize clinical development of efgartigimod in its ongoing severe autoimmune indications.
