Biohaven and Pfizer enter strategic collaboration for the commercialization of rimegepant outside of the USA.

Rimegepant is commercialized as Nurtec ODT in the U.S., and is indicated for the acute treatment of migraine attacks with or without aura and the preventive treatment of episodic migraine in adults. An application for the approval of rimegepant is currently under review by the European Medicines Agency and several additional regulatory authorities outside of the U.S.

Under the terms of the arrangement, Biohaven would remain primarily responsible for further clinical development of rimegepant and the parties will cooperate in regulatory activities to secure approval for the product. Biohaven will continue to solely commercialize Nurtec ODT in the U.S and Pfizer would commercialize rimegepant, upon approval, in all regions outside the U.S. Additionally, per the arrangement, Pfizer gains rights outside of the U.S. to zavegepant, a third generation, high affinity, selective and structurally unique, small molecule CGRP receptor antagonist, currently being studied in an intranasal delivery and a soft-gel formulation in Phase III clinical trials for migraine indications.
