|---|---|
| Main Objective: To evaluate the effect of AMG 334 compared to placebo on the change from baseline in monthly migraine days, in subjects with chronic migraine;Secondary Objective: Efficacy: • To evaluate the effect of AMG 334, compared to placebo, on the proportion of subjects with at least 50% reduction from baseline in monthly migraine days, in subjects with chronic migraine • To evaluate the effect of AMG 334, compared to placebo, as measured by the change from baseline on monthly migraine-specific medication treatment usage • To evaluate the effect of AMG 334 compared to placebo as measured by change from baseline on monthly cumulative hours of headache Safety: To evaluate the safety and tolerability of AMG 334;Primary end point(s): Change in monthly migraine days from baseline to the last 4 weeks of the 12-week double-blind treatment phase;Timepoint(s) of evaluation of this end point: Change in monthly migraine days from baseline to the last 4 weeks of the 12-week double-blind treatment phase, calculated based on the following: (number of migraine days during the last 4 weeks of the double-blind treatment phase, ie, between weeks 9 and 12) - (number of migraine days during the 4-week baseline phase) | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Efficacy: • At least a 50% reduction from baseline in monthly migraine days in the last 4 weeks of the 12-week double-blind treatment phase • Change from baseline on monthly migraine-specific medication treatment days in the last 4 weeks of the 12-week double-blind treatment phase •Change from baseline in cumulative monthly headache hours in the last 4 weeks of the 12-week double-blind treatment phase Safety: • Adverse events • Clinical laboratory values and vital signs • Anti-AMG 334 antibodies;Timepoint(s) of evaluation of this end point: For full details, please refer to the schedule of assessments table in the protocol. | — |
