Clinical Trial Summary

Randomized, double-blind, placebo-controlled, parallel-group, multicenter study followed by an open-label treatment phase (OLTP). To evaluate the effect of erenumab (AMG 334) compared to placebo on the change from baseline in monthly migraine days.

Description:

This is a Phase 2, randomized, double-blind, placebo-controlled study in participants with episodic migraine. The study's double blind treatment phase (DBTP) is designed to evaluate if treatment with erenumab once a month for 6 months compared with placebo is effective in reducing the mean monthly migraine days. Additionally, this study will continue to evaluate the efficacy and safety of erenumab during the OLTP where participants will continue to receive active treatment monthly.

The study also includes a clinical home use (CHU) sub-study to assess a participant's ability to self-administer 140 mg of erenumab. Participants will be randomized 1:1 to use either 2 pre-filled 70 mg/mL autoinjector (AI)/pens or 1 pre-filled 140 mg/mL AI/pen. Participation in the substudy is optional, and no additional samples will be collected for the sub-study.

After implementation of Protocol Amendment 2, the dose of erenumab in the OLTP increased from 70 mg to 140 mg QM. Participants who had already completed week 48 remain on 70 mg QM, participants not yet starting the OLTP, or not yet completing the week 48 visit receive erenumab 140 mg QM for the remainder of the OLTP.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline in Mean Monthly Migraine Days at Months 4, 5 and 6	A migraine day was defined as any calendar day in which the participant experienced a qualified migraine headache (onset, continuation or recurrence of the migraine headache). A qualified migraine headache was a migraine with or without aura, lasting for = 30 minutes, and meeting at least one of the following criteria: a) = 2 of the following pain features: unilateral, throbbing, moderate to severe, exacerbated with exercise/physical activity; b) = 1 of the following associated symptoms: nausea and/or vomiting, photophobia and phonophobia. Change from baseline was calculated using the mean monthly migraine days from months 4, 5 and 6 of the DBTP minus the number of migraine days during the 4-week baseline phase. Least squares (LS) mean was estimated using a generalized linear mixed model which included treatment, visit, treatment by visit interaction, stratification factor (current, prior only, or no prior/current treatment), and baseline value as covariates.	4-week baseline phase and months 4, 5 and 6 of DBTP.
Primary	CHU Sub-Study: Participant-Reported Outcome of Attempted Full-Dose Administration at Day 29 (Week 4) and Day 57 (Week 8)	On CHU day 29 and day 57, site staff interviewed sub-study participants and asked if they administered a full, partial, or no dose of erenumab (after explaining that a full dose means that the entire volume of the AI/pen was injected) and documented the participant's response in the electronic case report form. Data presented are the percentage of participants who reported "full administration," "not full administration," or "discontinued investigational product (ie, no dose)." (Day 1 of the CHU substudy occurred at any OLTP study visit [up to week 88] as long as the participant had previously received at least 1 OL dose of erenumab 140 mg.)	CHU day 29 (week 4) and day 57 (week 8)
Secondary	Percentage of Participants With at Least a 50% Reduction From Baseline in Mean Monthly Migraine Days at Months 4, 5 and 6	A migraine day was defined as any calendar day in which the participant experienced a qualified migraine headache (onset, continuation or recurrence of the migraine headache). A qualified migraine headache was a migraine with or without aura, lasting for = 30 minutes, and meeting at least one of the following criteria: a) = 2 of the following pain features: unilateral, throbbing, moderate to severe, exacerbated with exercise/physical activity; b) = 1 of the following associated symptoms: nausea and/or vomiting, photophobia and phonophobia.; At least a 50% reduction from baseline in monthly migraine days was determined if: (mean monthly migraine days over the last three months of the DBTP minus baseline monthly migraine days) * 100 / baseline monthly migraine days, was less than or equal to -50%.	4-week baseline phase and months 4, 5 and 6 of DBTP.
Secondary	Change From Baseline in Mean Monthly Acute Migraine-Specific Medication Treatment Days at Months 4, 5 and 6	An acute migraine-specific medication treatment day was defined as any calendar day during which the participant took a migraine-specific medication (ie, triptan or ergotamine-derivatives).; The change from baseline was calculated using the mean monthly acute migraine-specific medication treatment days over the last three months (months 4, 5 and 6) of the DBTP minus the baseline monthly acute migraine-specific medication treatment days.; LS mean was estimated using a generalized linear mixed model which included treatment, visit, treatment by visit interaction, stratification factor (prior/current treatment), and baseline value as covariates.	4-week baseline phase and months 4, 5 and 6 of DBTP.
Secondary	Number of Participants With Treatment Emergent Adverse Events (TEAEs), Serious TEAEs, Discontinuations Due to TEAEs, and Fatal TEAEs During the DBTP	An adverse event (AE) is defined as any untoward medical occurrence in a clinical trial participant. A serious adverse event (SAE) is defined as an adverse event that meets at least 1 of the following serious criteria: fatal; life threatening; requires in-patient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; congenital anomaly/birth defect; other medically important serious event. Events were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03 (grade 1=mild, grade 2=moderate, grade 3=severe, grade 4= life-threatening, grade 5=death).	From first dose of IP up to week 24
Secondary	Number of Participants With TEAEs, Serious TEAEs, Discontinuations Due to TEAEs, and Fatal TEAEs During the OLTP	An AE is defined as any untoward medical occurrence in a clinical trial participant. An SAE is defined as an adverse event that meets at least 1 of the following serious criteria: fatal; life threatening; requires in-patient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; congenital anomaly/birth defect; other medically important serious event. Events were graded according to the NCI CTCAE version 4.03 (grade 1=mild, grade 2=moderate, grade 3=severe, grade 4= life-threatening, grade 5=death).	From first dose of IP in the OLTP (week 24) through the end of the OLTP (week 100) plus 12 weeks
Secondary	Number of Participants With TEAEs, Serious TEAEs, Discotninuations Due to TEAEs, Fatal TEAEs, and Adverse Device Effects During the CHU Sub-Study	An AE is defined as any untoward medical occurrence in a clinical trial participant. An SAE is defined as an adverse event that meets at least 1 of the following serious criteria: fatal; life threatening; requires in-patient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; congenital anomaly/birth defect; other medically important serious event. Events were graded according to the NCI CTCAE version 4.03 (grade 1=mild, grade 2=moderate, grade 3=severe, grade 4= life-threatening, grade 5=death). TEAEs leading to discontinuation of IP are TEAEs leading to complete discontinuation of erenumab regardless of CHU IP or parent study IP.	CHU sub-study day 1 through day 85 (end of CHU sub-study). Day 1 of the CHU substudy occurred at any OLTP study visit (up to week 88) as long as the participant had previously received at least 1 OL dose of erenumab 140 mg.
Secondary	Number of Participants With Post-Baseline Liver Function Test Abnormalities During the DBTP	Post-baseline is defined as any assessment done after the first dose of IP. Liver Function tests included alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBL). ULN=upper limit of normal.	From the first dose of study IP through the end of the DBTP (up to week 24)
Secondary	Number of Participants With Post-Baseline Liver Function Test Abnormalities During the OLTP	Post-baseline is defined as any assessment done after the first dose of OLTP IP. Liver Function tests included alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBL). ULN=upper limit of normal.	From the first dose of OLTP IP (week 24) through the end of the OLTP (up to week 100)
