Sumario:PURPOSE: Evaluate changes from baseline in health-related quality of life (QoL) in Japanese patients with episodic migraine receiving preventive treatment with galcanezumab (GMB). PATIENTS AND METHODS: Preventive treatments for migraine have been shown to improve QoL, but few clinical trials have examined QoL outcomes in Japanese patients. This phase 2, randomized, double-blind, placebo-controlled study was conducted at 40 centers in Japan. Patients aged 18–65 years with episodic migraine (4–14 monthly migraine headache days) received GMB 120 mg (n=115), 240 mg (n=114), or placebo (PBO, n=230) as monthly subcutaneous injections for 6 months. QoL was measured monthly using the Migraine-Specific Quality-of-Life Questionnaire (MSQ) version 2.1. Prespecified analyses were differences between GMB and PBO for change from baseline in all 3 domains of the MSQ and MSQ-Total, for each month and the average over Months 4–6. RESULTS: Treatment with GMB significantly increased MSQ scores from baseline vs PBO. Average change ± SE from baseline across Months 4–6 was 10.12±0.72 (PBO), 17.13±1.03 (GMB 120 mg; P<0.001), and 15.91±1.03 (GMB 240 mg; P<0.001) for MSQ Role Function-Restrictive; 4.80±0.65 (PBO), 9.64±0.93 (GMB 120 mg; P<0.001), and 8.35±0.93 (GMB 240 mg; P<0.05) for MSQ Role Function-Preventive (MSQ-RFP); 3.46±0.77 (PBO), 10.04±1.10 (GMB 120 mg; P<0.001), and 7.73±1.10 (GMB 240 mg; P<0.05) for MSQ Emotional Function, and 7.14±0.67 (PBO), 13.46±0.95 (GMB 120 mg; P<0.001), and 11.98±0.95 (GMB 240 mg; P<0.001) for MSQ-Total. Significantly greater improvement in scores in all MSQ domains and MSQ-Total was observed for both GMB doses vs PBO at Month 1 and was maintained for Months 1–6 (excluding Month 5 for MSQ-RFP). CONCLUSION: Preventive treatment with GMB 120 mg/240 mg improves MSQ scores in Japanese patients with episodic migraine. Improvements were seen within the first month and maintained for 6 months and are similar to those seen in global studies enrolling primarily Caucasian patients.
