What this Trial Is About
Researchers are evaluating Xeomin injections as a treatment to prevent chronic migraine in adults. This Phase 3 clinical trial compares the change in monthly migraine days between participants receiving Xeomin injections and those receiving placebo injections. The study involves participants diagnosed with chronic migraine who meet specific migraine frequency criteria. Participants will receive four treatments approximately 12 weeks apart, with injections administered into muscles in the head and neck at specific points. The trial includes a placebo-controlled period with two Xeomin dose groups and a placebo group, followed by an extension period where all participants may receive Xeomin. Treatments involve Xeomin or placebo injections prepared by reconstitution with saline. The study lasts about 52 to 55 weeks, including a 4 to 5 week screening period and multiple visits. Four visits are on-site for treatments, while others are remote via phone or video call. Researchers will monitor changes in migraine days and headache days, use of acute migraine medication, and any treatment-related side effects. The primary outcome is the change in monthly migraine days from before treatment to six months after the first injection.
