REGN has recently been in the spotlight after the U.S. Food and Drug Administration (FDA) approved Dupixent® (dupilumab) for treating allergic fungal rhinosinusitis in patients aged six and older. While this development is seen as a significant milestone for Regeneron Pharmaceuticals, market reactions indicate a cautious approach from investors.
