Migraine is a debilitating disorder that affects about 15% of adults. A Migraine is characterized by moderate to severe throbbing pain or a pulsing sensation, usually on one side of the head. A person with migraine often has nausea, vomiting, and sensitivity to light and sound. Migraine attacks can last for hours to days and the pain can be so bad that it interferes with your daily activities.
If you have had little success with your current migraine treatments, our migraine clinical trial may be an option for you.
This clinical trial will help us learn if the study medicine (called rimegepant) can treat migraine pain and relieve symptoms in adults with migraine.
Participants in this trial will receive care from a team of dedicated medical professionals and help to advance medical research for adults who experience migraine.
After completing the first phase of the study, participants may be eligible to participate in a second phase of the study where everyone will receive the study medicine.
Who may participate
Joining a clinical trial is an important and personal decision. We thank you for considering participation as an option that may be right for you.
You might be able to participate in this trial if you:
- Are 18 years of age or older
- Have had a diagnosis of migraine for at least one year, which started before the age of 50
- Have migraine attacks that last about 4-72 hours when they are not treated
- Experience 4-14 migraine days a month
- Have been unsuccessful with at least 2 triptan* medications (for example, triptans did not improve your migraine symptoms, or you had side effects when taking triptans), or you could not use triptans due to a safety concern
*Examples of Triptan medications include:
- Almotriptan (Axert)
- Eletriptan (Relpax)
- Frovatriptan (Frova)
- Naratriptan (Amerge)
- Rizatriptan (Maxalt)
- Sumatriptan (Imitrex, Onzetra, Xsail, Sumavel, DosePro, Zembrace)
- Zolmitriptan (Zomig)

Each clinical study has its own guidelines for who can participate, called eligibility criteria. However, only the research study staff can determine if you qualify to enroll in the study.
What to expect
If you choose to participate, you will go through a screening assessment to see if this study is right for you.
If you are eligible, you will:
- Receive all clinical trial-related care and study medicine at no charge
- Receive close monitoring of your migraine attacks and overall health by a trial doctor
- Receive compensation for your time spent completing electronic questionnaires. You will also be reimbursed for any reasonable expenses you may have as a result of taking part in the study such as parking, meals, or other travel-related expenses.
If the screening assessments determine you’re eligible to continue participating, you will be assigned to receive either the study medicine (rimegepant) or placebo. A placebo does not contain any medicine in it but looks like the medicine being studied.
After completion of the first phase of the study, you may be eligible to participate in the second phase of the study. If you are eligible and choose to continue, you will receive the study medicine (rimegepant).
Length of study treatment
First phase: up to 45 days / Second phase: up to 12 weeks
Number of study visits
First phase: 3 clinic visits / Second phase: 1 phone visit and 4 clinic visits
Long-term follow up
Second Phase: up to 2 weeks

Frequently asked questions
What is the study medicine in this clinical trial?
This trial will investigate a study medicine (called rimegepant) which is thought to work by blocking pain signals in the brain.
During a migraine attack, nerve cells and blood vessels in the brain release substances that can cause pain signals. Some nerve cells contain special molecules that can detect these substances (called receptors). The study medicine is thought to work by blocking these receptors, so they cannot detect the substances that cause pain signals.
What is drug development?
Drug development is the journey from an idea for a potential medicine all the way through to bringing that new medicine to patients who need it. The development process includes laboratory research and a series of clinical trials. Along the way, important information is collected about the potential medicine and how it affects clinical trial participants. If that information shows the potential medicine is safe and effective, clinical trial sponsors provide the information to regulatory authorities, which decide whether to approve the medicine’s use by patients.
What are clinical trials?
Clinical trials (or research studies) are a type of medical research in which people volunteer to take part. Clinical trials commonly study how potential medicines and other medical treatments affect the participants.
All medicines and vaccines that become available today for use in patients are first tested in clinical trials involving hundreds to thousands of people.
What happens in a clinical trial?
What happens in a clinical trial depends on the ‘protocol.’ A protocol is a detailed plan that explains the purpose of the clinical trial and how it will be run. If you consider joining a clinical trial, these details will be explained to you as part of the informed consent process.
They include:
- the length of the clinical trial
- the study medicines, procedures, and tests in the clinical trial
- the schedule of study activities
- information about who can participate
- how side effects will be tracked, managed, and reported
- the rules that must be followed
Who will oversee my care in a clinical trial? Can I continue to see my regular medical doctor?
- As part of a clinical trial, your study-related medical care is provided by the study team at the location where you’re participating. This includes the principal investigator (or study doctor) — the healthcare professional who conducts and takes responsibility for the trial at that location — as well as other clinical study team members.
- During your clinical trial, you may also continue to see your regular medical doctors for any care that is not related to the study. It is important for you to tell your study team about other conditions you might have, and to let them know which other doctors are caring for you. This helps the study team coordinate your overall care.
- If you participate, the clinical trial will provide study-related medical care, and your regular medical doctors will address the other aspects of your health. Your regular medical doctors can also work with the study team to understand the details of the study and any impact it may have on your regular medical care.
Are clinical trials safe?
All clinical trials have possible risks. The known and unknown risks of participating in a specific study will be explained to you during the informed consent process that happens before you decide whether to participate.
Clinical researchers must follow guidelines and regulatory requirements to help protect the rights, safety, and well-being of clinical trial participants. These include Good Clinical Practice (GCP). GCP is an international ethical and scientific quality standard for designing and conducting clinical trials.
There are also many entities that provide oversight of clinical trials. These include health authorities or regulators, institutional review boards and independent ethics committees, and data safety and monitoring boards.
Who can join a clinical trial?
We encourage everybody to consider joining clinical trials. There are many types of clinical trials that study different aspects of health in people with a variety of backgrounds and conditions. Each clinical trial has its own criteria for who may participate. These are called eligibility criteria.
Eligibility criteria include things like your age, sex, overall health, type of condition, and your medical treatment history. As part of the steps to join a clinical trial, the study doctor will confirm whether you meet all eligibility criteria and are able to participate.
Participation in a clinical trial is always voluntary. The decision to join is personal, and it is yours.
Is there any cost to participate in a clinical trial?
Pfizer generally covers the cost of the study medicines and procedures that are part of our clinical trials.
Pfizer is also committed to reimbursing participants for reasonable clinical trial-related expenses such as transportation, parking, and meals. Because each study is different, we encourage you to ask the study team any questions you have. You can also refer to the informed consent document for the details about any costs for study participants and study-related reimbursement.
