About Rimegepant
Rimegepant is Biohaven's orally-dosed calcitonin gene-related peptide (CGRP) receptor antagonist, which the Company is developing as an acute 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 has now been consistently established across three randomized controlled trials to date: the two recently announced pivotal Phase 3 studies, and a previously reported Phase 2b study. The co-primary endpoints achieved in the Phase 3 trials are consistent with regulatory guidance from the U.S. Food and Drug Administration (FDA) and provide the basis for a planned submission of a new drug application (NDA) to the FDA in 2019.
