Researchers are evaluating the effect of Xeomin injections compared to placebo injections for preventing chronic migraine. This Phase 3, randomized, double-blind, placebo-controlled trial includes an extension period and aims to measure changes in the number of monthly migraine days. Participants have chronic migraine and meet specific criteria related to headache frequency and migraine history. Participants receive Xeomin or placebo injections into muscles of the head and neck at pericranial and cervical points. The study includes two Xeomin dose groups and a placebo group during the controlled period, with all groups receiving Xeomin in the extension phase. Four treatments are given approximately 12 weeks apart over a total study duration of 52 to 55 weeks. Participants take part in 14 visits over the study period, with the first, last, and four treatment visits conducted in person and the remaining eight visits by phone or video call. Researchers collect headache and migraine data from diaries and assess changes in monthly migraine days as the primary outcome. Safety is monitored by tracking treatment-related adverse events throughout the trial.

Researchers are evaluating the use of Xeomin injections to prevent episodic migraine. This Phase 3 clinical trial compares Xeomin to placebo injections in the muscles of the head and neck to measure changes in the number of monthly migraine days. Participants have episodic migraine with or without aura, and the study aims to assess the efficacy and safety of different Xeomin doses over time. Participants receive a series of four Xeomin or placebo injections spaced about 12 weeks apart. The study includes two experimental groups receiving different Xeomin doses and a placebo group, followed by an extension period where some participants receive Xeomin. Injections are given at specific points around the head and neck. The trial lasts approximately 52 to 55 weeks, starting with a 4 to 5 week screening period. Participants attend about 14 visits, including the first and last visits and four treatment visits conducted on-site, with other visits done remotely by phone or video call. Researchers monitor changes in monthly migraine days, headache days, and medication use, as well as any treatment-related side effects throughout the study.
