Condition(s) targeted: Chronic Migraine

Intervention: cyclobenzaprine hydrochloride (Drug); placebo (Drug)

Phase: Phase 3

Status: Terminated

Sponsored by: Kennedy Medical Group

Official(s) and/or principal investigator(s):

Summary

The primary objective of the study is to evaluate the effectiveness and safety of cyclobenzaprine hydrochloride extended release (Amrix 15mg/day) for the prophylaxis of chronic migraine compared to a placebo medication. A second objective, is to find out whether there is an improvement in quality of sleep and self-reported depression in patients taking Amrix 15mg daily. The hypothesis is that the number of migraine days per month of patients treated with Amrix 15mg daily will be significantly lower than those patients treated with placebo.
