ObjectiveMigraine is a chronic, disabling neurological disease affecting >1 billion people worldwide. Migraine remains undertreated in Asia, including Taiwan. Galcanezumab is a humanized monoclonal antibody that selectively binds calcitonin gene-related peptide, a peptide firmly established in the pathophysiology of migraine, with demonstrated efficacy and safety in patients with episodic or chronic migraine. Our objective was to evaluate the efficacy and safety of galcanezumab in Taiwanese patients with episodic or chronic migraine.MethodsWe conducted a sub-group analysis of the Taiwanese cohort from two double-blind, placebo-controlled, Phase 3 clinical trials of galcanezumab in the prevention of episodic and chronic migraine, EVOLVE-2 (NCT02614196) and REGAIN (NCT02614261), respectively. During the EVOLVE-2 and REGAIN double-blind periods, 2092 patients were randomly assigned to receive monthly injections of either placebo, 120 mg galcanezumab (240 mg loading dose), or 240 mg galcanezumab. In REGAIN, a 9-month open-label period followed. Post-hoc analysis on the Taiwanese population across both trials included 106 patients, 45 of whom continued into the open-label period in REGAIN.ResultsOur findings show that galcanezumab has similar efficacy and safety in the Taiwanese population, as compared to the "All Patients" population included in the study. Galcanezumab treatment reduced the number of monthly migraine headache days, determined a higher percentage of patients with a ≥ 50% response, and positively impacted quality of life.ConclusionGalcanezumab is a promising therapeutic for the preventive treatment of migraine in the Taiwanese population.
