Key clinical point: Galcanezumab is an effective and safe long-term treatment option for chronic migraine.
Major finding: At month 12, patients in the placebo, 120 mg galcanezumab, and 240 mg galcanezumab groups showed a mean change of −8.5, −9.0, and −8.0 days in monthly migraine days from the beginning of the double-blind period, respectively (all within-group P < .001). No new safety concerns emerged with extended treatment.
Study details: Findings are from the 9-month open-label extension of the REGAIN trial including 1022 patients with chronic migraine who completed the preceding 3-month double-blind treatment (501, 259, and 262 patients assigned to the placebo, 120 mg galcanezumab, and 240 mg galcanezumab groups, respectively) and received a 240-mg galcanezumab loading dose, followed by 120 mg in the next month and flexible dosing thereafter.
