On May 17, 2018, the U.S. Food and Drug Administration approved erenumab-aooe (Aimovig) for the preventive treatment of migraine in adults. Erenumab is a human monoclonal antibody that targets calcitonin gene-related peptide (CGRP) receptor, thereby blocking the activity of CGRP, which is involved in migraine attacks. The treatment is given by once-monthly subcutaneous injections.

The approval was based on data from three clinical trials that compared erenuman-aooe to placebo. Over 2000 participants were included in the studies. In the first study (STRIVE, NCT02456740), which included 955 participants with a history of episodic migraine, patients administered erenumab-aooe experienced, on average, one to two fewer Monthly Migraine Days than those on placebo over a 6 month period. In the second study (ARISE, NCT02483585), which included 577 patients with a history of episodic migraine, patients administered erenumab-aooe experienced, on average, one fewer migraine day per month than those on placebo over a 3 month period. The third study, which evaluated 667 patients with a history of chronic migraine, patients treated with erenumab-aooe experienced, on average, 2.5 fewer monthly migraine days than those receiving placebo over a three month period.
