About this Migraine Prevention Study

This is a research study, or clinical trial, to test a new investigational medication. An investigational medication is one that is not approved by the US FDA. The purpose of the research study is to test how well zavegepant works compared to a placebo (like a sugar pill) as a preventative treatment in people with chronic migraine.

About 2,900 study participants could be screened and about 1,440 study participants could enter into the double blind treatment phase. Double blind means that neither you, your doctor, or the study sponsor Biohaven, will know if you are taking zavegepant or placebo (like sugar pill).

Migraine study details

This study will test how well zavegepant works compared to a placebo (like a sugar pill) to prevent migraines from occurring in peopl with chronic migraine. This will be measured by counting the number of migraine days you have each month.


If you qualify, your participation in this study will last approximately 24 weeks (1 month taking your usual migraine medications, 3 months taking zavagepant or placebo and 2 months follow up, when you are no taking zavegepant or placebo). You will have 9 study visits to the study center. Some of the participants in this study will take 100 mg zavegepant daily, some will take 200 mg zavegepany daily, and some subjects will take placebo (like a sugar pill).

What is a clinical trial?

Before a medication can be approved for treatment, the FDA requires that it be tested in a clinical study to evaluate the safety and efficacy of the drug.

Clinical trials take place in medical centers around the world, and involve volunteers helping doctors look at new ways to treat conditions.

Clinical trials represent the latest research about your condition, and can offer new treatment options.

Migraine is a chronic and debilitating disorder that affects approximately 15% of the population.

Migraines are characterized by recurrent attacks lasting 4 to 72 hours with multiple symptoms, including pulsating (throbbing) headaches of moderate to severe pain that could be associated with nausea or vomiting, and/or sensitivity to sound (phonophobia) and sensitivity to light (photophobia).
