Effects of fremanezumab on migraine-associated symptoms and medication use in Japanese and Korean patients with episodic migraine: Exploratory endpoint analysis of a multicenter, randomized, double-blind, placebo-controlled trial
Abstract
OBJECTIVE: To describe exploratory endpoints from a previous phase 2b/3 placebo-controlled trial conducted in Japan and Korea, specifically investigating the effect of fremanezumab or placebo on migraine-associated symptoms and acute headache medication use in patients with episodic migraine (EM).
BACKGROUND: EM is associated with non-head pain symptoms, including nausea, vomiting, photophobia, or phonophobia, which contribute substantially to the disease burden, healthcare resource utilization, and impaired quality of life. Current EM treatments include a mix of nonspecific/migraine-specific acute headache medications, but medication overuse can induce headaches and progression from EM to chronic migraine (CM). In multiple phase 2b/3 trials, the monoclonal antibody fremanezumab significantly reduced the average number of monthly migraine days experienced by patients with EM/CM compared with placebo.
METHODS: This was a prespecified analysis of exploratory endpoints in a multicenter, randomized, double-blind, placebo-controlled, phase 2b/3 trial conducted in Japanese and Korean patients with EM (NCT03303092). Patients were randomized to receive fremanezumab, either monthly or quarterly, or matching placebo, administered subcutaneously at 4-week/28-day ("monthly") intervals to maintain blinding. Exploratory endpoints reported here were the mean change from baseline in the number of days/month with (i) the use of any acute headache medication, (ii) the use of any…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 121 participants or records.
