Official title

TOGETHER STUDY: Tandem OnabotulinumtoxinA Galcanezumab Emerging Therapeutic Headache Elimination Research Study

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a multicenter, double-blind, placebo-controlled study assessing the effectiveness of Galcanezumab as an add-on therapy for Migraine participants on a stable migraine prophylaxis regimen including Botox with or without one other migraine prophylaxis agent (BMPT), who have persistent unmet need. The study population will consist of approximately 150 participants ages 18-65 who report at least a 30% reduction in monthly migraine days from BMPT and still experience an average of ≥ 6 migraine days per month, following International Classification of Headache Disorders (ICHD-3) criteria. Subjects should be stable on at least 2, but no more than 8, consecutive injection cycles of Botox. Overall migraine day reduction will be assessed in the participants based on participant self-report (via daily electronic diaries) and medical record review.
