Clinical pipeline supports long term

Beyond Vyvgart, Argenx continues to advance a broad pipeline of antibody-based therapies targeting autoimmune and immune-mediated conditions.

In its Q1 2024 update, Argenx reported progress in expanding Vyvgart into additional indications, including chronic inflammatory demyelinating polyneuropathy (CIDP) and immune thrombocytopenia (ITP).
