Data pooled from the phase 2 CM, STRIVE, ARISE, LIBERTY, and EMPOwER studies (safety analysis set). The summary shows TEAEs with onset day within the first 3 months (91 days) from the first administration of erenumab/placebo. Preferred terms are sorted in descending frequency of AEs in the 70/140 mg column and then alphabetically. A participant with multiple AEs is counted only once in the “at least one AE” row. A participant with multiple AEs with the same preferred term is counted only once for that preferred term
