About

To explore the relationship between clinical response to erenumab and genetic biomarkers

Full description

This is a phase 4 open-label study aiming to explore the relationship between clinical response to erenumab and genetic biomarkers.

Subjects with episodic or chronic migraine will be treated with Erenumab 70mg or 140mg for a 4-week baseline/screening period, followed by a 24-week treatment period.

Subjects will collect migraine-related parameters daily using an eDiary and blood samples will be collected for biomarker research. All analysis will be descriptive in nature.

Subject has provided informed consent prior to initiation of any study-specific activities/procedures
Age greater than or equal to 18 years upon entry into screening
History of migraine (with or without aura) for greater than or equal to 12 months before screening according to the International Headache Society (IHS) Classification ICHD-3 (Headache Classification Committee of the International Headache Society, 2018) based on medical records and/or patient self report
Greater than or equal to 4 headache days that meet criteria as migraine days per month on average across the 3 months before screening After baseline period

Exclusion criteria

Subjects are excluded from the study if any of the following criteria apply:

Disease Related

Greater than 50 years of age at migraine onset
History of cluster headache or hemiplegic migraine headache
Inability to differentiate between migraine from other headaches. Other Medical Conditions
The subject is at risk of self-harm or harm to others as evidenced by past suicidal behaviour
History or evidence of any other clinically significant disorder, condition or disease (with the exception of those outlined above) that, in the opinion of the investigator or Amgen physician, if consulted, would pose a risk to subject safety or interfere with the study evaluation, procedures or completion.
