calcitonin gene-related peptide


To explore the relationship between clinical response to erenumab and response to intravenous infusion of calcitonin gene-related peptide in individuals with migraine.


This is a single-center, non-randomized, single-arm, open-label study, in which adults with episodic or chronic migraine will receive intravenous infusion with calcitonin gene-related peptide and subsequently be treated with erenumab. The study will consist of the following

  • Provocation Phase (1 experimental day with intravenous infusion of calcitonin gene-related peptide)
  • Screening/Baseline Phase (4 weeks)
  • Open-Label Treatment Phase (24 weeks)

Condition Migraine, Migraine (Pediatric), Migraine (Adult), Primary Stabbing Headache, Migraine and Cluster Headaches, Migraine (Adult), Migraine and Cluster Headaches, Migraine (Pediatric), migraines
Treatment Calcitonin Gene-Related Peptide, Erenumab
