Study Endpoints
Primary Endpoints
Time to Maximum Concentration (Tmax) of Erenumab
First dose: Days 1 (pre-dose), 8, 15, and 29 (pre-dose); third dose: Days 57 (pre-dose), 64, 71, and 85

Blood samples for pharmacokinetic (PK) testing were collected for the measurement of PK concentrations. Serum erenumab concentrations were determined using a validated assay. Noncompartmental analysis (NCA) was performed for erenumab PK parameter estimation.

Maximum Observed Concentration (Cmax) of Erenumab
First dose: Days 1 (pre-dose), 8, 15, and 29 (pre-dose); third dose: Days 57 (pre-dose), 64, 71, and 85

Blood samples for PK testing were collected for the measurement of PK concentrations. Serum erenumab concentrations were determined using a validated assay. NCA was performed for erenumab PK parameter estimation.

Trough Concentration (Ctrough) of Erenumab
First dose: Days 1 (pre-dose), 8, 15, and 29 (pre-dose); third dose: Days 57 (pre-dose), 64, 71, and 85

Blood samples for PK testing were collected for the measurement of PK concentrations. Serum erenumab concentrations were determined using a validated assay. NCA was performed for erenumab PK parameter estimation.

Area Under the Concentration Time Curve From 0 to 28 Days (AUC0-28day) of Erenumab
First dose: Days 1 (pre-dose), 8, 15, and 29 (pre-dose); third dose: Days 57 (pre-dose), 64, 71, and 85

Blood samples for PK testing were collected for the measurement of PK concentrations. Serum erenumab concentrations were determined using a validated assay. NCA was performed for erenumab PK parameter estimation.

Number of Participants With Treatment-emergent Adverse Events (TEAEs)
Up to Week 52 + 16-week safety follow-up

An adverse event (AE) was defined as any untoward medical occurrence in a clinical study participant. A TEAE was defined as an AE starting on or after first dose of investigational product. The event did not necessarily have a causal relationship with study treatment.

Number of Participants With Clinically Significant Changes in Vital Signs Measurements
Up to Week 52 + 16-week safety follow-up

The following measurements were performed: systolic/diastolic blood pressure, heart rate, and temperature.

Number of Participants With Clinically Significant Changes in Electrocardiogram (ECG) Measurements
Up to Week 52

Clinically significant changes in ECG was defined as incidence of abnormal ECG diagnosis based on 12-lead ECG including heart rate, QRS, QTc and PR intervals.

Number of Participants With Clinically Significant Changes in Clinical Laboratory Safety Tests
Up to Week 52 + 16-week safety follow-up

The clinical laboratory safety tests included: chemistry, hematology, and urinalysis.

Number of Participants With Clinically Significant Changes in Neurological Assessments
Up to Week 52 + 16-week safety follow-up

The neurological examinations were completed as per standard of care.
