Men and woman ≥ 18 years old that are diagnosed with migraine with or without aura for at least 1 year, who report a reliable migraine trigger. Acceptable triggers for the study will include exercise, alcohol (less than one drink per day for woman and less than two drinks per day for men), air travel that lasts no more than 12 hours, sexual activity, fasting that lasts no more than 24 hours, stress or stress let-down headache.
Interventions
DRUG
Rimegepant 75 MG
The interventional product is rimegepant ODT 75 mg. Rimegepant 75mg ODT will be given 2 hours prior to a trigger exposure for exercise, alcohol (less than one drink per day for woman and less than two drinks per day for men), air travel that lasts no more than 12 hours, sexual activity, fasting that lasts no more than 24 hours rimegepant will be dosed 2 hours prior to trigger exposure. For weekend or let down headache and changes in sleep pattern, rimegepant will be dosed the night before. The maximum dose in a 24-hour period is 75mg.
Primary outcome measures
Percentage of preemptive treatments with rimegepant in which migraine with a moderate to severe headache intensity
Time frame: 24 hour post dose
Percentage of preemptive treatments with rimegepant in which migraine with a moderate to severe headache intensity occurs within 24 hours

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
