Results from a 12-month, open-label safety study in patients with migraine1
In a 12-month, open-label safety study of patients with episodic or chronic migraine with 4 or more MHDs per month1

Meet Jessicaa
Migraine continues to impact her work and personal life during and between attacks
- 4-14 unpredictable migraine headache days (MHDs) per month
- Has tried therapeutic doses of 2 standard-of-care generic preventives
- May now be only relying on her acute treatments
She isn't sure another preventive will give her the results she is looking for.

Contraindications
Emgality is contraindicated in patients with serious hypersensitivity to galcanezumab-gnlm or to any of the excipients.
Primary Endpoint Result
No new safety findings were identified for Emgality over a 12-month treatment period1
Treatment-emergent adverse events (TEAEs) were predominantly rated as mild or moderate in severity.2
- 54 patients on Emgality 120 mg experienced a TEAE possibly related to study treatment during the 12-month treatment period. The most prevalent TEAEs were injection site pain, injection site reaction, and injection site erythema.1,2
- 6 patients discontinued Emgality 120 mg due to adverse events. 2 patients discontinued due to injection site reaction, 1 patient discontinued due to injection site erythema, and 1 patient discontinued due to lethargy. Other discontinuations due to adverse events were not determined to be related to study treatment.1-3
- Of the 54 TEAEs possibly related to study treatment, 27 were deemed mild, 21 were deemed moderate, and 6 were deemed severe.4

Secondary Endpoint Result
Overall mean change from baseline in the number of monthly MHDs over Months 1 to 121
Mean reduction in monthly MHDs in a 12-month, open-label safety study: Over Months 1 to 12, the overall reduction in the number of monthly MHDs for Emgality 120 mg (N=135) was 5.6 compared to baseline 9.7.1
These are observations from the 12-month, open-label safety study of which efficacy measures were a secondary endpoint. Data from the open-label safety study have limitations, as the study was not blinded or placebo-controlled. These findings cannot be considered statistically significant.1

Hypersensitivity Reactions
Hypersensitivity reactions, including dyspnea, urticaria, and rash, have occurred with Emgality in clinical studies and the postmarketing setting. Cases of anaphylaxis and angioedema have also been reported in the postmarketing setting. If a serious or severe hypersensitivity reaction occurs, discontinue administration of Emgality and initiate appropriate therapy. Hypersensitivity reactions can occur days after administration and may be prolonged.

Secondary Endpoint Results
Percentage of patients with ≥50%, ≥75%, and 100% reductions in monthly MHDs from baseline over Months 1 to 121
Mean percentage of patients meeting defined levels of reduction in monthly MHDs in a 12-month, open-label safety study over Months 1 to 12: On average, 66% had ≥50% reduction, 45% had ≥75% reduction, and 21% had 100% reduction with Emgality 120 mg (N=135).1
These are observations from the 12-month, open-label safety study of which efficacy measures were a secondary endpoint. Data from the open-label safety study have limitations, as the study was not blinded or placebo-controlled. Results should be interpreted with these factors in mind.1
In REGAIN, Emgality 120 mg was not significantly better than placebo for the mean percentage of patients with ≥75% or 100% reduction from baseline in the number of monthly MHDs over the 3-month treatment period.8

Adverse Reactions
The most common adverse reactions (incidence ≥2% and at least 2% greater than placebo) in Emgality clinical studies were injection site reactions.
Emgality was studied in patients with episodic or chronic migraine in a 12-month, Phase 3 trial1
The trial was a 12-month, open-label safety study assessed primarily for safety and tolerability and, secondarily, for effectiveness in patients with episodic or chronic migraine1
Patient population (N=270)1
- 79% of patients enrolled were diagnosed with episodic migraine
- 21% of patients enrolled were diagnosed with chronic migraine
- Patients 18 to 65 years of age
- Migraine was defined as
- Meeting International Classification of Headache Disorders-3 beta (ICHD-3 beta) criteria for diagnosis
- A history of at least 1 year of migraine headaches
- Migraine onset prior to 50 years of age
- A history of ≥4 MHDs per month, on average, for 3 months prior to study entry
- A history of at least 1 headache-free day per month for 3 months prior to study entry
Exclusion criteria1
- Patients with prior exposure to Emgality or any other calcitonin gene-related peptide (CGRP) antibody treatment
- Patients on any antibody therapy 12 months prior to study entry
- Patients on a migraine preventive treatment
- Patients who failed on ≥3 classes of migraine preventive treatments (as defined by the American Academy of Neurology treatment guidelines Level A or Level B evidence)
- Patients with certain medical conditions, including pregnancy, suicidal ideation within 1 month prior to study entry, and substance abuse or dependence within 1 year of study entry
- Patients with acute cardiovascular events and/or serious cardiovascular events based on history or electrocardiogram (ECG) findings
- Participants were randomized to once-monthly placebo, Emgality 120 mg after an initial loading dose of 240 mg, or Emgality 240 mg. 240 mg is an unapproved dose
-
Acute treatments for headache, including migraine-specific medications (ie, triptans, ergotamine derivatives), nonsteroidal anti-inflammatory drug (NSAIDs), and acetaminophen were allowed
- 15% of patients continued 1 concomitant preventive treatment
Study Period 1 (3-45 days)1
- Initial screening procedures
- Washout of all migraine preventive treatments
Study Period 2 (open-label treatment period)1,8
-
Patients were randomized to once-monthly Emgality 120 mg (N=135) or Emgality 240 mg (N=135) for 12 doses total
- Patients on Emgality 120 mg received an initial loading dose of 240 mg and all subsequent doses were 120 mg
- Patients on Emgality 240 mg received 240 mg each month. 240 mg is not an approved dose
- Acute medicationsa (ie, triptans, ergots, nonsteroidal anti-inflammatory drugs [NSAIDs], and acetaminophen) for the treatment of migraine were allowed
- Treatment was delivered by prefilled syringe or autoinjector by patients or caregivers (after appropriate training)
- Patients kept track of their headaches (migraine and non-migraine) and use of medication taken for acute treatment of migraine and non-migraine headache for the last 30 days, every month of the 12-month study
- Patients were required to report a migraine headache, headache, or the use of acute medication on a daily basis with a diary or log for monthly review
Study Period 3 (washout phase)1
- Patients no longer received treatment, but continued to track headache information and received safety assessments for 4 months in the post-treatment period
Prespecified key endpoints1
- Primary endpoint: Safety and tolerability of Emgality for up to 1 year of treatment
- Secondary endpoint: Effectiveness of Emgality as assessed by the overall mean change from baseline and mean percentage of patients with ≥50%, ≥75%, and 100% reduction from baseline in the number of monthly MHDs over 12 months of treatment1
Data from the open-label safety study have limitations, as the study was not blinded or placebo-controlled. Results should be viewed with these factors in mind.1
