Group Intervention Description Erenumab Placebo Participants 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). Placebo Placebo Participants 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). Placebo Sumatriptan Participants 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). Erenumab Sumatriptan Participants 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). Erenumab Erenumab Participants 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).
- Primary Outcome Measures
Name Time Method 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 Outcome Measures
Name Time Method 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. Plasma concentrations of sumatriptan were quantified using a validated high performance liquid chromatographic method with tandem mass spectrometry detection. The area under the plasma concentration-time curve from time 0 to infinity (AUCinf) after the 2nd 6 mg dose of sumatriptan was estimated as the sum of AUClast and Clast/λz where Clast is the last observed concentration and λz is the first-order terminal rate constant estimated via linear regression of the terminal log-linear decay phase. Sumatriptan plasma concentrations below the lower limit of quantification (LLOQ) (0.100 ng/mL) were set to 0 before data analysis.
Log-transformed AUCinf was analyzed using a linear mixed effects model with treatment as a fixed effect and subject as a random effect. Sumatriptan Alone data include participants from both Groups A (Parts 1 and 2) and B (Part 1 only).Maximum Observed Plasma Concentration (Cmax) of Sumatriptan Day 2 and day 5 at predose, 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. Plasma concentrations of sumatriptan were quantified using a validated high performance liquid chromatographic method with tandem mass spectrometry detection. Sumatriptan plasma concentrations below the lower limit of quantification (LLOQ) (0.100 ng/mL) were set to 0 before data analysis.
Log-transformed maximum observed plasma concentration (Cmax) was analyzed using a linear mixed effects model with treatment as a fixed effect and subject as a random effect. Sumatriptan Alone data include participants from both Groups A (Parts 1 and 2) and B (Part 1 only).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. Adverse events (AEs) were graded according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 and according to the following:
Grade 1 = Mild AE, asymptomatic or mild symptoms; Grade 2 = Moderate, minimal, local or noninvasive intervention indicated; Grade 3 = Severe or medically significant but not immediately life-threatening; Grade 4 = Life-threatening consequences, urgent intervention indicated; Grade 5 = Death related to AE.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. Plasma concentrations of sumatriptan were quantified using a validated high performance liquid chromatographic method with tandem mass spectrometry detection.
Area under the plasma concentration-time curve from time 0 to 6 hours post dose (AUC6hr) after the 2nd 6 mg dose of sumatriptan was estimated using the linear trapezoidal method. Sumatriptan plasma concentrations below the lower limit of quantification (LLOQ; 0.100 ng/mL) were set to 0 before data analysis.
Log-transformed AUC6hr was analyzed using a linear mixed effects model with treatment as a fixed effect and subject as a random effect.
Sumatriptan Alone data include participants from both Groups A (Parts 1 and 2) and B (Part 1 only).Number of Participants Who Developed Anti-erenumab Antibodies Baseline and day 89 Two validated assays were used to detect the presence of anti-erenumab antibodies. All samples were first tested in an electrochemiluminescence-based bridging assay to detect antibodies capable of binding to erenumab (Binding Antibody Assay). Samples confirmed to be positive for binding antibodies were subsequently tested in a cell-based assay to determine neutralizing activity against erenumab (Neutralizing Antibody Assay). If a post-dose sample was positive for binding antibodies and demonstrated neutralizing activity at the same time point, the sample was defined as positive for neutralizing antibodies.
Binding/neutralizing antibody positive is defined as participants with an antibody positive postbaseline results and with a negative or no result at baseline.
