|
E.2.2 | Secondary objectives of the trial |
To evaluate the effect of erenumab compared with placebo on the change in monthly headache days from baseline to week 9 through week 12 of the DBTP. - To evaluate the effect of erenumab compared with placebo on the proportion of subjects with at least 50% reduction in MMDs from baseline to week 9 through week 12 of the DBTP. - To evaluate the effect of erenumab compared with placebo on change in MMDs from baseline to the average of the first 3 months of the DBTP. - To evaluate the effect of erenumab compared with placebo on change in MMDs from baseline to the average of the 6-month DBTP. - To evaluate the effect of erenumab compared with placebo on change in monthly average severity of migraine attacks from baseline to week 9 through week 12 of the DBTP. - To evaluate the effect of erenumab compared with placebo on change in migraine-related disability and productivity as measured by the modified Pediatric Migraine Disability Assessment from baseline to month 3 of the DBTP |
