Inclusion criteria

Key Inclusion Criteria: 1. Patient has at least 1 year history of migraines (with or without aura), consistent with a diagnosis according to the International Classification of Headache Disorder, 3rd Edition, Beta version\[1\] including the following: * Not more than 8 attacks of moderate or severe intensity per month within last 3 months * Consistent migraine headaches of at least 2 migraine headache attacks of moderate or severe intensity in each of the 3 months prior to the Screening Visit and maintains this requirement during the Screening Period 2. Less than 15 days with headache (migraine or non-migraine) per month in each of the 3 months prior to the Screening Visit and maintains this requirement during the Screening Period 3. Patients on prophylactic migraine medication are permitted to remain on therapy provided they have been on a stable dose for at least 3 months prior to study entry. 4. Patients with contraindications for use of triptans may be included provided they meet all other study entry criteria. Key

Exclusion criteria

1. Patient history of HIV disease 2. Patient history with current evidence of uncontrolled, unstable or recently diagnosed cardiovascular disease, such as ischemic heart disease, coronary artery vasospasm, and cerebral ischemia. Patients with Myocardial Infarction (MI), Acute Coronary Syndrome (ACS),Percutaneous Coronary Intervention (PCI), cardiac surgery, stroke or transient ischemic attack (TIA) during the 6 months prior to screening. 3.

Patient has a current diagnosis of major depression, other pain syndromes, psychiatric conditions (eg, schizophrenia), dementia, or significant neurological disorders (other than migraine) that, in the Investigator's opinion, might interfere with study assessments 5. Patient has a history of gastric, or small intestinal surgery, or has a disease that causes mal-absorption 6. The patient has a history or current evidence of any significant and/or unstable medical conditions (eg, history of congenital heart disease or arrhythmia, known suspected infection, hepatitis B or C, or cancer) that, in the investigator's opinion, would expose them to undue risk of a significant adverse event (AE) or interfere with assessments of safety or efficacy during the course of the trial 7.

Design outcomes

Primary

MeasureTime frameDescription
Percentage of Participants With Freedom From Pain at 2 Hours Post-dose2 hours post-dosePain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the electronic diary (eDiary). Pain freedom was defined as pain level of none.
Percentage of Participants With Freedom From Most Bothersome Symptom (MBS) at 2 Hours Post-dose2 hours post-doseMBS was reported as nausea, photophobia, or phonophobia at migraine onset using the eDiary. Symptom status (absent, present) was assessed post-dose using the eDiary separately for nausea, photophobia, and phonophobia.

Recruitment details

The study was conducted at 50 centers in the United States.

Pre-assignment details

A total of 1485 participants were enrolled, of which 1162 participants were randomized to BHV-3000 (rimegepant) 75 milligram (mg) or placebo. A total of 323 participants failed screening mainly due to failure to meet eligibility criteria.The randomization was stratified in a 1:1 ratio based on use of prophylactic migraine medications (yes or no).
