A new intravenous treatment for the prevention of migraine has been approved by the US Food and Drug Administration on the basis of trial data showing that patients had a sustained reduction in their disease episodes for a period of months after receiving the drug. The treatment, Vyepti (eptinezumab), is a monoclonal antibody that binds to the human calcitonin gene-related peptide with the result that migraine attacks are reduced. It was developed by Alder BioPharmaceuticals Inc, a company that was acquired by H. Lundbeck A/S of Denmark in 2019.
