Pharmaceutical Information

• Pharmacodynamics: Eptinezumab is experimentally administered as an intravenous infusion and/or subcutaneous injection. During Phase 3 clinical trials, it was noted that patients with episodic migraine who on average had 8.6 days of migraine per month demonstrated significant reductions in migraine frequency over weeks 1-12, associated with the 300mg dose arm. Additionally, 29.7% of patients achieved a 75% or greater reduction in migraine days from baseline, compared to 16.2% for placebo (p<0.0007). Moreover, a post hoc analysis revealed that those patients achieving a 75% or greater response rate had over an eight-fold increase in days between migraines.
• Targets: Calcitonin gene-related peptide 1 Calcitonin gene-related peptide 2
