Eptinezumab reduces mean monthly migraine days

In the phase 3 PROMISE-1 trial, efficacy and safety of eptinezumab for the prevention of episodic migraine through 1 year was evaluated. Administered intravenously every 12 weeks, it reduced mean monthly migraine days over weeks 1-12. Additional infusions achieved sustained or incremental reductions [1].

Eptinezumab is a calcitonin gene-related peptide receptor antagonist. In PROMISE-1, eligible adults with episodic migraine were randomised to 4 infusions every 12 weeks of eptinezumab 30 mg, 100 mg, 300 mg, or placebo. The primary endpoint was change in mean monthly migraine days in the first 3 months (see Table). In the efficacy population (n=888) baseline mean monthly migraine days were ~8.5.

Also presented were results of the PROMISE-2 trial, investigating the impact of eptinezumab on patient global impression of change (PGIC) and self-reported most bothersome associated symptom (MBAS) in patients with chronic migraine [2]. The efficacy population included 1,072 patients (100 mg, n=356; 300 mg, n=350; placebo, n=366). After 4 weeks, MBAS was much or very much improved in 45.0%, 56.9%, and 28.9% of patients, respectively. PGIC was much or very much improved in 45.0%, 59.0%, and 32.3%, respectively. Improvement was maintained or further improved after 12 and 24 weeks. The similar trends in MBAS and PGIC improvement across time points suggest these are highly correlated.
