Brief summary:
The primary purpose of this study is to determine whether erenumab is safe and well tolerated in healthy adults and migraine patients. As part of the secondary objectives, this study will be conducted to characterize the pharmacokinetic (PK) profile of erenumab after single subcutaneous (SC) or intravenous (IV) doses in healthy participants and migraine patients as well as to characterize the effect of erenumab on the capsaicin-induced increase in dermal blood flow after single SC or IV doses in healthy participants and migraine patients.

Detailed description:
This study was a single-dose, double-blind, placebo-controlled, sequential dose escalation study in which participants were to be enrolled into 8 cohorts.

In Part 1 healthy participants were randomized in a 3:1 ratio (erenumab:placebo) into 6 cohorts: 5 cohorts received the investigational product (IP) as an SC administration and 1 cohort received it as an IV administration. In Part 2 a total of 12 migraine patients were randomized in a 1:1 ratio (erenumab:placebo) in cohort 7. An additional 8 migraine patients could have been enrolled and randomized in a 3:1 ratio in the optional cohort 8, however this cohort was not enrolled.

Arms:
arm 1: Participants received a single dose of erenumab by subcutaneous injection at doses of 1 mg, 7 mg, 21 mg, 70 mg, 140 mg, and 210 mg or by IV injection at a dose of 140 mg. arm 2: Participants received a single dose of matching placebo administered by SC or IV injection.

Interventions: intervention 1: Erenumab intervention 2: Placebo
Intervention descriptions: intervention 1: Administered by subcutaneous injection or intravenous injection intervention 2: Administered by subcutaneous injection or intravenous injection
