Patients aged between 18 and 65 years with episodic migraine were randomized to receive a monthly injection of galcanezumab (120 mg: N = 115, 240 mg: N = 114) or placebo (N = 230) for 6 months. Outcome measures included onset of effect at weekly and daily intervals—assessed by change from baseline in the number of migraine headache days and the proportion of patients with migraine headache—with galcanezumab versus placebo. To further confirm the onset and maintenance effect, the 50% response rate was also evaluated.Results: The mean change from baseline in weekly migraine headache days was significantly reduced with galcanezumab (– 0.97 days) compared with placebo (– 0.10 days) at week 1 (p ≤ 0.0001), which was maintained at all subsequent weeks up to week 4 (all p ≤ 0.0001 vs placebo). A significantly smaller proportion of galcanezumab-treated patients had migraine headache compared with placebo-treated patients at day 1 after the first injection (13.6% vs 31.4%, respectively; p ≤ 0.0001), which was also maintained at all subsequent days during the first week after the first injection. Furthermore, the 50% response rate was significantly higher with galcanezumab compared with placebo from week 1 through month 6.Conclusion: The onset of the migraine preventive effect of galcanezumab was rapid compared with placebo, starting from day 1 after the first injection in Japanese patients with episodic migraine. The effect was maintained during the first week and first month, and throughout 6 months of monthly injections of galcanezumab. Galcanezumab is a promising preventive treatment in Japanese patients with episodic migraine.Keywords: calcitonin gene-related peptide, galcanezumab, Japan, migraine disorders, onset of effect, maintenance effect

Introduction This analysis evaluated the treatment satisfaction of Japanese patients receiving galcanezumab (GMB) as a preventive medication for episodic migraine (4–14 monthly migraine headache days). Methods This phase 2, randomized, double-blind, placebo-controlled study enrolled patients aged 18–65 years at 40 centers in Japan. Patients were randomized 2:1:1 to receive monthly subcutaneous injections of placebo (PBO, n = 230), GMB 120 mg (n = 115), or GMB 240 mg (n = 114) for 6 months. Patients’ experience with treatment was measured using the Patient Global Impression of Severity (PGI-S), Patient Global Impression of Improvement (PGI-I), and Patient Satisfaction with Medication Questionnaire-Modified (PSMQ-M) scales. PGI-S was administered at baseline and months 1–6, PGI-I at months 1–6, and PSMQ-M at months 1 and 6. Prespecified analyses were differences between GMB and PBO in PGI-I and the change from baseline in PGI-S, and evaluating positive responses for the PGI-I and PSMQ-M. Results Average change ± SE from baseline across months 1–6 was − 0.09 ± 0.05 (PBO), − 0.17 ± 0.07 (GMB 120 mg, p = 0.33), and − 0.30 ± 0.07 (GMB 240 mg, p = 0.013) for PGI-S. Average PGI-I across months 1–6 was 3.39 ± 0.05 (PBO), 2.55 ± 0.07 (GMB 120 mg, p

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.Clinical Trial Registration: ClinicalTrials.gov, NCT02959177 (registered November 7, 2016).Keywords: MeSH: preventive therapy, quality of life

Because of the burden of migraine in Japan, there is a need for safe and effective preventive treatments. This study assessed the long-term safety and tolerability of galcanezumab in Japanese patients with episodic (EM) or chronic (CM) migraine.In this 12-month open-label study, adult patients with EM who previously completed a 6-month, double-blind, placebo-controlled trial were newly randomized to either galcanezumab dose from placebo or continued their assigned galcanezumab doses (all: 120 mg, n = 120; 240 mg, n = 126). Newly enrolled patients with CM were randomized to 120-mg (n = 32) or 240-mg (n = 33) galcanezumab. The primary outcome was long-term safety and tolerability.The incidence of TEAEs was similar between treatment groups. Nasopharyngitis was the most common TEAE, followed by injection site reactions. The discontinuation rate was low (EM = 9.3%; CM = 15.4%) and no deaths were reported. Patients with EM who received galcanezumab in the placebo-controlled trial had sustained efficacy. Both doses reduced the number of migraine headache days in patients with CM.Long-term treatment with 120-mg or 240-mg galcanezumab was safe and effective in Japanese patients with EM or CM.https://clinicaltrials.gov, identifier: NCT02959190.

Objective:This study was designed to assess the efficacy and safety of galcanezumab in comparison with placebo for the prevention of migraine in Japanese patients with episodic migraine.Methods:In this double-blind, placebo-controlled study, which was conducted over 6 months, randomized adult patients received subcutaneous injections of galcanezumab (120 mg n = 115, 240 mg n = 114) or placebo ( n = 230) once monthly. The primary endpoint was the overall mean change from baseline in the number of monthly migraine headache days. The key secondary outcome measures were response rates (≥50%, ≥75%, and 100%); the Migraine-Specific Quality-of-Life Questionnaire Role Function-Restrictive score; monthly migraine headache days requiring acute treatment; and Patient Global Impression of Severity (PGI-S).Results:The mean change from baseline in monthly migraine headache days over months 1–6 was significantly ( p < 0.001) greater for the 120-mg galcanezumab dose (−3.60 days) and the 240-mg galcanezumab dose (−3.36 days) compared with placebo (−0.59 days). Both the 120-mg and 240-mg doses of galcanezumab were superior compared with placebo for each of the key secondary endpoints except for PGI-S (only the 240-mg dose was superior). The most commonly reported treatment-emergent adverse events were local injection-site reactions; erythema, swelling, pruritus, and pain were more commonly reported by patients who were treated with galcanezumab than those treated with placebo.Conclusion:The number of monthly migraine headache days was reduced with both doses of galcanezumab, and both doses were safe and well tolerated in Japanese patients with episodic migraine.
