Study Endpoints
Primary Endpoints
Time-weighted Averages of Mean Arterial Pressure
Days 2 and 5 from predose to 2.5 hours after sumatriptan dosing.

Mean arterial pressure (MAP) is the average arterial pressure during a single cardiac cycle. MAP was calculated as diastolic blood pressure (DBP) + 0.33 \* (systolic blood pressure \[SBP\]-DBP). Individual time-weighted average in MAP were calculated as area under the measurement-time curve from predose through 2.5 hours of MAP divided by the time period over which the measurements were made (ie, AUCmap0-2.5 hr /2.5 hours). Data were analyzed using a linear mixed effects regression model with fixed effects for treatment and period and random effect for subject; Sumatriptan Alone data include participants from both Groups A (Parts 1 and 2) and B (Part 1 only).

Secondary Endpoints
Number of Participants With Adverse Events
From the first dose of study drug (sumatriptan, placebo or erenumab) until 84 days after the last dose (89 days). Part 1 includes AEs from day 1 to predose on day 4 and Part 2 includes AEs from day 4 through day 89.
Area Under the Concentration-time Curve From Time 0 to 6 Hours for Sumatriptan
Day 2 and day 5 at 1 hour (prior to 2nd sumatriptan injection), 1 hour 10 minutes, 1.25, 1.5, 2, 3, 4.5, and 7 hours relative to the first 6 mg dose of sumatriptan.
Area Under the Concentration-time Curve From Time 0 to Infinity for Sumatriptan
Day 2 and day 5 at 1 hour (prior to 2nd sumatriptan injection), 1 hour 10 minutes, 1.25, 1.5, 2, 3, 4.5, and 7 hours relative to the first 6 mg dose of sumatriptan.

PlaceboPLACEBO_COMPARATORParticipants received a placebo intravenous (IV) infusion on day 1 then 12 mg subcutaneous sumatriptan on day 2 (Part 1). After a 2-day washout participants received another placebo IV infusion on day 4 followed by 12 mg subcutaneous sumatriptan on day 5 (Part 2).
ErenumabEXPERIMENTALParticipants received a placebo intravenous (IV) infusion on day 1 then 12 mg subcutaneous sumatriptan on day 2 (Part 1). After a 2-day washout participants received 140 mg erenumab IV infusion on day 4 followed by 12 mg subcutaneous sumatriptan on day 5 (Part 2).
