Participants received placebo on day 1 and at weeks 4 and 8 by subcutaneous injection during the double-blind treatment phase. In the open-label treatment phase participants received 70 mg erenumab QM from week 12 to week 264 (last dose). After Protocol Amendment 3, participants still on study had their dose increased to 140 mg QM.
