If Eli Lilly and Co. had been hoping its migraine drug, Emgality (galcanezumab), would emerge with unequivocal superiority against Pfizer Inc.’s Nurtec ODT (rimegepant orally disintegrating tablet), giving the once-monthly injectable biologic an advantage in the highly competitive CGRP space, the pharma firm likely was disappointed. Findings from the phase IV Challenge-MIG study did not meet the primary endpoint, which called for Emgality’s statistical superiority over Nurtec ODT on the percentage of patients achieving a 50% or greater reduction in monthly migraine days.
