The first medicine designed to prevent migraines was approved by the Food and Drug Administration on Thursday, ushering in what many experts believe will be a new era in treatment for people who suffer the most severe form of these headaches.
The drug, Aimovig, made by Amgen and Novartis, is a monthly injection with a device similar to an insulin pen. The list price will be $6,900 a year, and Amgen said the drug will be available to patients within a week.
Aimovig blocks a protein fragment, CGRP, that instigates and perpetuates migraines. Three other companies — Lilly, Teva and Alder — have similar medicines in the final stages of study or awaiting F.D.A. approval.
