Also called BHV-3000
75 mg tablet QD
PlaceboDrug

| Study group | Role | What they receive |
|---|---|---|
| Rimegepant 75 mg | Experimental | Participants were administered a single oral dose of 75 mg of rimegepant tablet on occurrence of migraine that reached moderate or severe intensity up to 45 days after randomization. Receives: Drug: Rimegepant |
| Placebo | Placebo comparator | Participants were administered a single oral dose of matching placebo tablet for rimegepant (75 mg) on occurrence of migraine that reached moderate or severe intensity up to 45 days after randomization. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With Freedom From Pain at 2 Hours Post-dose
Pain 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.
Measured: 2 Hours post-dose
Percentage of Participants With Freedom From Most Bothersome Symptom (MBS) at 2 Hours Post-dose
MBS 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. Freedom from MBS was defined as MBS reported at onset that was absent post-dose.
Measured: 2 Hours
Secondary outcomes (11)
Percentage of Participants With Freedom From Photophobia at 2 Hours Post-dose
Photophobia (sensitivity to light) status was measured as absent or present in the eDiary. Freedom from photophobia was defined as photophobia absent.
Measured: 2 hours post-dose
Percentage of Participants With Freedom From Phonophobia at 2 Hours Post-dose
Phonophobia (sensitivity to sound) status was measured as absent or present in the eDiary. Freedom from phonophobia was defined as phonophobia absent.
Measured: 2 hours post-dose
Percentage of Participants With Pain Relief at 2 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eDiary. Pain relief was defined as pain level of none or mild.
Measured: 2 hours post-dose
Percentage of Participants With Freedom From Nausea at 2 Hours Post-dose
Nausea status was measured as absent or present in the eDiary. Freedom from nausea was defined as nausea absent.
Measured: 2 hours post-dose
Percentage of Participants With Rescue Medication Use Within 24 Hours Post-dose
Participants who did not experience relief of their migraine headache at the end of 2 hours after dosing with study medication (and after the 2-hour assessments had been completed on the eDiary) were permitted to use the following rescue medications: aspirin, ibuprofen, acetaminophen up to 1000 mg/day (this includes Excedrin Migraine), naproxen (or any other type of nonsteroidal anti-inflammatory drug), antiemetics (e.g., metoclopramide or promethazine), or baclofen. The participant's use of rescue medication was recorded by the participant in a paper diary.
Measured: 24 hours post-dose
Percentage of Participants With Sustained Pain Freedom From 2 to 24 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eDiary. Sustained pain freedom was defined as pain level of none at 2 hours up to 24 hours post-dose with no rescue medication use through 24 hours post-dose.
Measured: From 2 hours up to 24 hours post-dose
Percentage of Participants With Sustained Pain Relief From 2 to 24 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eDiary. Sustained pain relief was defined as pain level of none or mild at 2 hours up to 24 hours post-dose with no rescue medication use through 24 hours post-dose.
Measured: From 2 hours up to 24 hours post-dose
Percentage of Participants With Sustained Pain Freedom From 2 to 48 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eDiary. Sustained pain freedom was defined as pain level of none at 2 hours up to 48 hours post-dose with no rescue medication use through 48 hours post-dose.
Measured: From 2 hours up to 48 hours post-dose
Percentage of Participants With Sustained Pain Relief From 2 to 48 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eDiary. Sustained pain relief was defined as pain level of none or mild at 2 hours up to 48 hours post-dose with no rescue medication use through 48 hours post-dose.
Measured: From 2 hours up to 48 hours post-dose
Percentage of Participants With Pain Relapse From 2 to 48 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eDiary. Pain relapse was defined as pain level of mild, moderate, or severe after 2 hours up to 48 hours for the participants who were pain-free at 2 hours post-dose.
Measured: From 2 hours up to 48 hours post-dose
Percentage of Participants With Freedom From Functional Disability at 2 Hours Post-dose
Functional disability level was assessed in the eDiary on a 4-point scale: normal function, mild impairment, severe impairment, required bed rest. Freedom from functional disability was defined as normal function.
Measured: 2 hours post-dose

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Rimegepant in people with Migraine, With or Without Aura, run by Pfizer at 50 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 50 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 23 Dec 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants With Freedom From Pain at 2 Hours Post-dose (time frame: 2 Hours post-dose). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03237845, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Feb 2023.
