Study Summary
This trial is testing if rimegepant can prevent cluster headaches.
Who is the study for?
This trial is for individuals with recurrent cluster headaches not caused by another disorder. Participants must have had MR imaging to rule out other causes, experience specific symptoms like severe unilateral pain and restlessness during attacks, and have a certain frequency of headaches. They can't join if they're near the end of a cluster cycle, have recent serious heart issues or are pregnant. Those on stable doses of certain headache medicines may be eligible.Check my eligibility
What is being tested?
The study tests rimegepant's effectiveness as a preventive treatment for cluster headaches. It aims to see if taking rimegepant reduces the frequency or severity of headache episodes in participants who meet strict criteria based on their headache patterns and associated symptoms.See study design
What are the potential side effects?
While not explicitly stated here, common side effects from similar treatments include nausea, dizziness, dry mouth, sleepiness and potential allergic reactions. As this is an investigational study, there may be unknown risks that will be monitored throughout the trial.
