Detailed Description:
Phase 2, multicenter, randomized, double-blind, placebo-controlled study of patients with chronic migraine. Approximately 651 subjects will be randomized to receive either placebo, or one of two AMG 334 subcutaneous (SC) doses every month for the duration of the 12-week double-blind treatment phase. There will also be safety follow-up visit after the treatment phase.
