Eptinezumab, sold under the brand name Vyepti, is a medication used to prevent migraines in adults.[2] It is used in those who have at least four migraines per month.[4] It is given by gradual injection into a vein.[2]

Common side effects include runny nose and allergic reactions.[2] While there is no evidence of harm in pregnancy, such use has not been well studied.[2] It is a monoclonal antibody that blocks calcitonin gene-related peptides (CGRP).[2]

Eptinezumab was approved for medical use in the United States in 2020 and Europe and the United Kingdom in 2022.[2][4][7] In the United States it costs about 1,700 USD per dose as of 2022.[8] It is being studied in cluster headaches.[7]

Medical uses

It decreases migraines by about one to two day more per month more than a placebo in those who have frequent headaches.[4]


It is generally started at 100 mg over 30 minutes every three month.[4] This may be increased to 300 mg if needed.[4]


The U.S. Food and Drug Administration (FDA) approved eptinezumab based primarily on evidence from two clinical trials (Trial 1/ NCT02559895 and Trial 2/ NCT02974153) of 1741 subjects with chronic or episodic migraine headaches.[9] Trials were conducted at 212 sites in United States, Georgia, Russia, Ukraine and European Union.[9]

The benefit and side effects of eptinezumab were evaluated in two clinical trials of adult subjects 18 – 71 years of age with a history of migraine headaches.[9] The trials had similar designs.[9]

Trial 1 enrolled subjects with a history of episodic migraine headaches and Trial 2 enrolled subjects with chronic migraine headaches.[9] Subjects were assigned to receive one of two doses of eptinezumab or placebo injections every three months for a total of twelve months in Trial 1, and for a total of 6 months in Trial 2.[9] Neither the subjects nor the health care providers knew which treatment was being given until the trial was completed.[9]

The benefit of eptinezumab in comparison to placebo was assessed based on the change in the number of migraine days per month during the first three-month treatment period.[9]

Legal status

In November 2021, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) recommended the granting of a marketing authorization for the medicinal product Vyepti, intended for the prophylaxis of migraine.[4] The applicant for this medicinal product is H. Lundbeck A/S.[4] Eptinezumab was approved for medical use in the European Union in January 2022.[4]
