Researchers are evaluating the effectiveness and safety of Xeomin injections in preventing chronic migraine. This Phase 3 clinical trial compares Xeomin to placebo injections given into muscles of the head and neck. Participants have chronic migraine diagnosed for at least 12 months and meet specific headache and migraine day criteria. The study aims to measure changes in monthly migraine days over time with Xeomin treatment. Participants will receive four treatments spaced about 12 weeks apart over a total study duration of 52 to 55 weeks. The treatments involve injections of either Xeomin or placebo solution prepared with sodium chloride. Visits occur approximately every 4 weeks, totaling 14 visits: the first, last, and four treatment visits are on-site, while the other eight visits are remote via phone or video call. During the study, participants will keep headache diaries to track migraine and headache days. Researchers will focus on the change in monthly migraine days from baseline to six months after the first injection. Safety and effectiveness are monitored throughout, with frequent assessments during both on-site and remote visits to ensure accurate tracking of migraine symptoms and any side effects.

Researchers are evaluating the effect of Xeomin injections compared to placebo injections for preventing episodic migraine. This phase 3 clinical trial focuses on adults who experience episodic migraine, aiming to measure changes in the number of migraine days per month. Participants must have a diagnosis of episodic migraine for at least 12 months and meet specific headache frequency criteria. Participants will receive four treatments of either Xeomin or placebo injections into muscles of the head and neck, with treatments spaced about 12 weeks apart. The entire trial lasts approximately 52 to 55 weeks, beginning with a screening period of 4 to 5 weeks. There are about 14 visits in total, with the first, last, and four treatment visits conducted on-site, while the other visits are held remotely via phone or video. Throughout the study, participants will track their migraine days using a headache diary, and researchers will assess changes in monthly migraine frequency from baseline to six months after the first injection. Regular monitoring includes both in-person and remote assessments. The primary outcome focuses on the change in monthly migraine days between baseline and month six after treatment initiation.
