Eptinezumab – Migraine Prevention

Eptinezumab – Migraine Prevention

Eptinezumab (formerly known as ALD403) is our pivotal-stage monoclonal antibody that binds potently and selectively to inhibit calcitonin gene-related peptide (CGRP), a protein known to play a key role in migraine disease and progression. Eptinezumab the only investigational anti-CGRP therapy designed to be administered by quarterly infusion to allow for 100% of the dose available to inhibit CGRP.1


Eptinezumab is currently in multiple global, randomized pivotal, Phase 3 studies to assess its efficacy and safety in migraine prevention.
