About Rimegepant

Rimegepant is Biohaven's orally-dosed calcitonin gene-related peptide (CGRP) receptor antagonist, which the Company is developing as a treatment for migraine. Rimegepant represents a novel mechanism that targets the underlying pathophysiology of migraine without causing vasoconstriction. The efficacy and safety profile of rimegepant for the acute treatment of migraine has now been established across four randomized controlled trials to date: the three completed pivotal Phase 3 trials, and a Phase 2b trial. The co-primary endpoints achieved in all three Phase 3 trials are consistent with regulatory guidance from the FDA and form the basis of Biohaven's NDA submission to the FDA.
