What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing rimegepant, a medication that may help prevent cluster headaches. It targets patients who suffer from these severe headaches, especially those who don't respond well to other treatments. Rimegepant works by blocking pain signals in the brain. It was initially approved for treating migraines and is now being studied for preventing them.

Will I have to stop taking my current medications?

If you're taking verapamil, you'll need to stop using it during the study. However, if you're on other headache prevention medications, you can continue them as long as your dose has been stable for at least 2 months before the study and won't change during the study.

Is Rimegepant generally safe for humans?

Rimegepant has been generally well tolerated in clinical trials for migraine treatment, with no serious liver or heart-related side effects reported. Most side effects were mild or moderate and did not lead to stopping the treatment.12345

How does the drug Rimegepant differ from other treatments for cluster headache?

Rimegepant is unique because it is an orally disintegrating tablet that acts as a calcitonin gene-related peptide (CGRP) receptor antagonist, which is different from many traditional treatments for headaches. It offers convenience and potentially faster relief due to its quick-dissolve formulation, and it is already used for both acute and preventive treatment of migraines.12467

What data supports the effectiveness of the drug Rimegepant for treating cluster headaches?

Rimegepant is effective in treating migraines by blocking a protein involved in pain transmission, and it has been shown to reduce migraine symptoms and improve quality of life. While it is not specifically studied for cluster headaches, its success in treating migraines suggests it might help with similar headache conditions.12346

Are You a Good Fit for This Trial?

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.

Inclusion Criteria

This criterion requires that a headache is accompanied by at least one of the following:
You have been diagnosed with recurrent cluster headaches according to specific guidelines.
Subjects agree to refrain from starting a new prophylactic cluster headache medicine, including steroids and nerve blocks, during the course of the study.
