Summary

This trial is testing if taking rimegepant regularly can prevent occasional migraines by blocking a protein in the brain that triggers migraine pain. Rimegepant is a medication that is effective for migraine prevention.

Who is the study for?
This trial is for individuals who have had episodic migraines for at least a year, with onset before age 50. Participants should experience 4-14 migraine attacks per month and not be using any preventive migraine medication or certain painkillers frequently. Women must not be pregnant, breastfeeding, or planning to become pregnant without using contraception.
What is being tested?
The study aims to test the effectiveness and safety of Rimegepant in preventing episodic migraines when taken daily or every other day compared to a placebo (a substance with no active drug).
What are the potential side effects?
While specific side effects are not listed here, participants may experience adverse reactions related to Rimegepant which could include nausea, dizziness, fatigue, dry mouth and potential allergic reactions.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Migraine treatments work through various mechanisms to alleviate symptoms and prevent attacks. Calcitonin gene-related peptide (CGRP) receptor antagonists, like Rimegepant, block the CGRP receptors, which are involved in mediating pain and inflammation in migraines. This helps reduce the frequency and severity of migraine attacks. Triptans, another common treatment, activate serotonin (5-HT1B/1D) receptors, leading to the constriction of blood vessels and inhibition of pro-inflammatory neuropeptides, providing acute relief from migraine pain. Ergotamines also target serotonin receptors but have a broader action on multiple receptor types, which can make them effective but with a higher risk of side effects. Understanding these mechanisms is crucial for migraine patients as it helps in selecting the most appropriate treatment based on their specific symptoms and medical history, potentially improving outcomes and reducing the burden of migraines.
