What is eptinezumab?

Eptinezumab (Vyepti) is a prescription medicine used for migraine prevention, to reduce monthly migraine days for chronic migraines and episodic migraines in adults. Eptinezumab is given as an IV infusion every 3 months (four times a year).

Eptinezumab is from a class of medicines called calcitonin gene-related peptide antagonists.

Eptinezumab infusion works by blocking a protein called calcitonin gene-related peptide (CGRP), which is involved in migraines. CGRP levels increase during a migraine attack and may also be involved in the start of a migraine. It is thought that by blocking CGRP, eptinezumab reduces monthly migraine days. 

Eptinezumab brand name is Vyepti, by Lundbeck Seattle BioPharmaceuticals.

Eptinezumab-jjmr infusion received FDA approval on February 22, 2020.
