E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the effect of AMG 334 compared to placebo on the proportion of patients with at least 50% reduction from baseline in monthly migraine days |
|
E.2.2 | Secondary objectives of the trial |
-To evaluate the effect of AMG 334 compared to placebo on the change from baseline of monthly migraine days
-To evaluate the effect of AMG 334 compared to placebo on the "impact on everyday activities" domain as measured by the MPFID; -To evaluate the effect of AMG 334 compared to placebo on the "physical impairment" domain as measured by the Migraine Physical Function Impact Diary (MPFID); -To evaluate the effect of AMG 334 compared to placebo on change from baseline; -To evaluate the effect of AMG 334 compared to placebo on the proportion of patients with at least 75% reduction from baseline in monthly migraine days; -To evaluate the effect of AMG 334 compared to placebo on the proportion of patients with a 100% reduction from baseline in monthly migraine days; -To evaluate the safety, tolerability, and immunogenicity of AMG 334, -To evaluate clinical benefit as assessed by the investigator during the PTA Open-Label
