Condition/Disease

Chronic migraine

Objectives

Primary Objective: To test the hypothesis that at least one dose of LY2951742 (120 mg or 240 mg/month) is superior to placebo in the prevention of migraine in patients with chronic migraine. Key Secondary Objectives: If either LY2951742 dose (120 mg or 240 mg/month) demonstrates statistically significant superiority to placebo for the primary objective, multiplicity-adjusted testing will be conducted for the following key secondary objectives: Compare LY2951742 versus placebo for the 50% responder rate. Compare LY2951742 versus placebo for the 75% responder rate. Compare LY2951742 versus placebo for the 100% responder rate. Compare LY2951742 versus placebo for changes in functional impairment. Compare LY2951742 versus placebo for changes in the use of acute (symptomatic) migraine treatments. Compare LY2951742 versus placebo for changes in the overall severity of migraine condition.

Endpoints

Primary endpoint: Mean change from baseline in monthly migraine days (MMD) over the 3-month double-blind treatment period.

The Statistical Analysis Plan (SAP) will detail the specific methods for testing the following key secondary endpoints (including testing hierarchy, correlations, and allocation/transfer of Type I error):

Proportion of patients with a ≥50% reduction from baseline in MMD over the 3-month double-blind period.

Proportion of patients with a ≥75% reduction from baseline in MMD over the 3-month double-blind period.

Proportion of patients with a 100% reduction from baseline in MMD over the 3-month double-blind period.

Mean change from baseline to Month 3 in the Migraine-Specific Quality of Life Questionnaire Version 2.1 (MSQ v2.1) Role Function–Restrictive domain score.

Mean change in monthly migraine days requiring acute migraine/headache medications over the 3-month double-blind period.

Mean change from baseline to Month 3 in the Patient Global Impression of Severity (PGI-S) score.
