Key clinical point: Meta-analysis on 10 years of real-world data confirmed the efficacy of onabotulinumtoxinA as a preventive treatment for chronic migraine.
Major finding: At week 24, onabotulinumtoxinA reduced the number of headache days per month (mean change from baseline [MCFB] −10.64; 95% CI −12.31 to −8.97), with a ≥50% reduction in migraine days response rate of 46.57% (95% CI 29.50%-63.65%) and improvements in total Headache Impact Test-6 score (MCFB −11.70; 95% CI −13.86 to −9.54) and Migraine-Specific Quality of Life v2.1 score (MCFB 23.60; 95% CI 21.56-25.64). The improvements were maintained till 52 weeks.
Study details: Findings are from a systematic review and meta-analysis of 44 studies including patients with chronic migraine who received onabotulinumtoxinA.
Disclosures: This study was supported by AbbVie. M Lanteri-Minet reported receiving personal fees and grants from various sources. Four authors declared being employees of AbbVie or working for a consultancy company commissioned by AbbVie or holding stock options in GSK and AbbVie.
