Get your patient on Aimovig (Erenumab-Aooe)

The recommended dosage of AIMOVIG is 70 mg injected subcutaneously once monthly. Some patients may benefit from a dosage of 140 mg injected subcutaneously once monthly.

If a dose of AIMOVIG is missed, administer as soon as possible. Thereafter, AIMOVIG can be scheduled monthly from the date of the last dose.

AIMOVIG is for subcutaneous use only.

AIMOVIG is intended for patient self-administration. Prior to use, provide proper training to patients and/or caregivers on how to prepare and administer AIMOVIG using the single-dose prefilled autoinjector or single-dose prefilled syringe, including aseptic technique [see Instructions for Use] :

• Prior to subcutaneous administration, allow AIMOVIG to sit at room temperature for at least 30 minutes protected from direct sunlight [see How Supplied/Storage and Handling (16.2) ]. This is important for administering the entire dose and helps minimize discomfort. Do not warm by using a heat source such as hot water or a microwave.
• Do not shake the product.
• Inspect visually for particulate matter and discoloration prior to administration [see Dosage Forms and Strengths (3) ] . Do not use if the solution is cloudy or discolored or contains flakes or particles.
• Administer AIMOVIG in the abdomen, thigh, or upper arm subcutaneously. Do not inject into areas where the skin is tender, bruised, red, or hard.
• Both prefilled autoinjector and prefilled syringe are single-dose and deliver the entire contents.

Safety and effectiveness in pediatric patients have not been established.

Clinical studies of AIMOVIG did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Hypersensitivity reactions, including rash, angioedema, and anaphylaxis, have been reported with AIMOVIG in postmarketing experience. Most hypersensitivity reactions were not serious and occurred within hours of administration, although some occurred more than one week after administration. If a serious or severe hypersensitivity reaction occurs, discontinue administration of AIMOVIG and initiate appropriate therapy [see Contraindications (4) , and Patient Counseling Information (17) ] .

Constipation with serious complications has been reported following the use of AIMOVIG in the postmarketing setting. There were cases that required hospitalization, including cases where surgery was necessary. In a majority of these cases, the onset of constipation was reported after the first dose of AIMOVIG; however, patients have also presented with constipation later on in treatment. AIMOVIG was discontinued in most reported cases of constipation with serious complications. Constipation was one of the most common (up to 3%) adverse reactions reported in clinical studies [see Adverse Reactions (6.1) ] .

Monitor patients treated with AIMOVIG for severe constipation and manage as clinically appropriate [see Patient Counseling Information (17) ] . The concurrent use of medications associated with decreased gastrointestinal motility may increase the risk for more severe constipation and the potential for constipation-related complications.

Development of hypertension and worsening of pre-existing hypertension have been reported following the use of AIMOVIG in the postmarketing setting. Many of the patients had pre-existing hypertension or risk factors for hypertension. There were cases requiring pharmacological treatment and, in some cases, hospitalization. Hypertension may occur at any time during treatment but was most frequently reported within seven days of dose administration. In the majority of the cases, the onset or worsening of hypertension was reported after the first dose. AIMOVIG was discontinued in many of the reported cases.

Monitor patients treated with AIMOVIG for new-onset hypertension, or worsening of pre-existing hypertension, and consider whether discontinuation of AIMOVIG is warranted if evaluation fails to establish an alternative etiology.

Development of Raynaud's phenomenon and recurrence or worsening of pre-existing Raynaud's phenomenon have been reported in the postmarketing setting following the use of CGRP antagonists, including AIMOVIG. In reported cases with monoclonal antibody CGRP antagonists, symptom onset occurred a median of 71 days following dosing. Many of the cases reported serious outcomes, including hospitalizations and disability, generally related to debilitating pain. In most reported cases, discontinuation of the CGRP antagonist resulted in resolution of symptoms.

AIMOVIG should be discontinued if signs or symptoms of Raynaud's phenomenon develop, and patients should be evaluated by a healthcare provider if symptoms do not resolve. Patients with a history of Raynaud's phenomenon should be monitored for, and informed about the possibility of, worsening or recurrence of signs and symptoms.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The safety of AIMOVIG has been evaluated in 2537 patients with migraine who received at least one dose of AIMOVIG, representing 3040.2 patient-years of exposure. Of these, 2271 patients were exposed to 70 mg or 140 mg once monthly for at least 6 months, 1305 patients were exposed for at least 12 months, and 216 patients were exposed through 5 years.

In placebo-controlled clinical studies (Studies 1, 2, and 3) of 2184 patients, 787 patients received at least one dose of AIMOVIG 70 mg once monthly, 507 patients received at least one dose of AIMOVIG 140 mg once monthly, and 890 patients received placebo during 3 months or 6 months of double-blind treatment [see Clinical Studies (14) ] . Approximately 84% were female, 91% were white, and the mean age was 42 years at study entry.

The most common adverse reactions (incidence ≥ 3% and more often than placebo) in the migraine studies were injection site reactions and constipation. Table 1 summarizes the adverse reactions that occurred during the first 3 months in the migraine studies (Studies 1, 2, and 3).

In Studies 1, 2, and 3, 1.3% of patients treated with AIMOVIG 70 mg or 140 mg discontinued double-blind treatment because of adverse events. The most frequent injection site reactions were injection site pain, injection site erythema, and injection site pruritus.

The following adverse reactions have been identified during postapproval use of AIMOVIG. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Immune System Disorders: Hypersensitivity reactions, including rash, angioedema, and anaphylaxis [see Warnings and Precautions (5.1) ].

Gastrointestinal Disorders: Constipation with serious complications [see Warnings and Precautions (5.2) ] , oral mucosal ulceration .

Skin and Subcutaneous Tissue Disorders: Rash, alopecia.

Vascular Disorders: Hypertension [see Warnings and Precautions (5.3) ] , Raynaud's Phenomenon [see Warnings and Precautions (5.4) ].

Erenumab-aooe is a human monoclonal antibody that binds to the calcitonin gene-related peptide (CGRP) receptor and antagonizes CGRP receptor function.

In a randomized, double-blind, placebo-controlled study in healthy volunteers, concomitant administration of erenumab-aooe (140 mg intravenous, single-dose) with sumatriptan (12 mg subcutaneous, given as two 6 mg doses separated by one hour) had no effect on resting blood pressure compared with sumatriptan alone. AIMOVIG is for subcutaneous use only.

Erenumab-aooe exhibits non-linear kinetics as a result of binding to the CGRP receptor. The C _max mean and AUC _last mean following subcutaneous administration of a 70 mg once monthly and a 140 mg once monthly dose in healthy volunteers or migraine patients are included in Table 2.

Less than 2-fold accumulation was observed in trough serum concentrations (C _min ) for episodic and chronic migraine patients following subcutaneous administration of 70 mg once monthly and 140 mg once monthly doses (see Table 2 ). Serum trough concentrations approached steady state by 3 months of dosing. The effective half-life of erenumab-aooe is 28 days.

The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of erenumab-aooe.

The immunogenicity of AIMOVIG has been evaluated using an immunoassay for the detection of binding anti-erenumab-aooe antibodies. For patients whose sera tested positive in the screening immunoassay, an in vitro biological assay was performed to detect neutralizing antibodies.

In controlled studies with AIMOVIG [see Clinical Studies (14) ] , the incidence of anti-erenumab-aooe antibody development was 6.2% (48/778) in patients receiving AIMOVIG 70 mg once monthly (2 of whom had in vitro neutralizing activity) and 2.6% (13/504) in patients receiving AIMOVIG 140 mg once monthly (none of whom had in vitro neutralizing activity). In a long-term study, including 12 weeks of double-blind treatment and up to 256 weeks of open-label treatment, the incidence of anti-erenumab-aooe antibody development was 11.1% (25/225) among patients whose AIMOVIG dose was 70 mg or 140 mg (2 of whom had in vitro neutralizing activity). The neutralizing anti-erenumab-aooe antibody positive rate may be underestimated because of limitations of the assay. Although these data do not demonstrate an impact of anti-erenumab-aooe antibody development on the efficacy or safety of AIMOVIG in these patients, the available data are too limited to make definitive conclusions.

Episodic Migraine

Study 1 (NCT 02456740) was a randomized, multi-center, 6-month, placebo-controlled, double-blind study evaluating AIMOVIG for the preventive treatment of episodic migraine. A total of 955 patients with a history of episodic migraine were randomized to receive either AIMOVIG 70 mg (N = 317), AIMOVIG 140 mg (N = 319), or placebo (N = 319) by subcutaneous injection once monthly (QM) for 6 months. Patients were allowed to use acute headache treatments including migraine-specific medications (i.e., triptans, ergotamine derivatives) and NSAIDs during the study.

The study excluded patients with medication overuse headache as well as patients with myocardial infarction, stroke, transient ischemic attacks, unstable angina, coronary artery bypass surgery, or other revascularization procedures within 12 months prior to screening.

The primary efficacy endpoint was the change from baseline in mean monthly migraine days over months 4 to 6. Secondary endpoints included the achievement of a ≥ 50% reduction from baseline in mean monthly migraine days over months 4 to 6 ("≥ 50% MMD responders"), the change from baseline in mean monthly acute migraine-specific medication days over months 4 to 6, and the change from baseline in mean Migraine Physical Function Impact Diary (MPFID) over months 4 to 6. The MPFID measures the impact of migraine on everyday activities (EA) and physical impairment (PI) using an electronic diary administered daily. Monthly MPFID scores are averaged over 28 days, including days with and without migraine; scores are scaled from 0 to 100. Higher scores indicate worse impact on EA and PI. Reductions from baseline in MPFID scores indicate improvement.

A total of 858 (90%) patients completed the 6-month double-blind study. Patients had a median age of 42 years (range: 18 to 65 years), 85% were female, and 89% were white. Three percent of patients were taking concomitant preventive treatments for migraine. The mean migraine frequency at baseline was approximately 8 migraine days per month and was similar across treatment groups.

AIMOVIG treatment demonstrated statistically significant improvements for key efficacy endpoints compared to placebo, as summarized in Table 3.

Figure 2 shows the distribution of change from baseline in mean monthly migraine days over months 4 to 6 in bins of 2 days by treatment group. A treatment benefit over placebo for both doses of AIMOVIG is seen across a range of changes from baseline in monthly migraine days.

Compared to placebo, patients treated with AIMOVIG 70 mg once monthly and 140 mg once monthly showed greater reductions from baseline in mean monthly MPFID everyday activity scores averaged over months 4 to 6 [difference from placebo: −2.2 for AIMOVIG 70 mg and −2.6 for AIMOVIG 140 mg; p- value < 0.001 for both], and in mean monthly MPFID physical impairment scores averaged over months 4 to 6 [difference from placebo: −1.9 for AIMOVIG 70 mg and −2.4 for AIMOVIG 140 mg; p- value < 0.001 for both].

Study 2 (NCT 02483585) was a randomized, multi-center, 3-month, placebo-controlled, double-blind study evaluating AIMOVIG for the preventive treatment of episodic migraine. A total of 577 patients with a history of episodic migraine were randomized to receive either AIMOVIG 70 mg (N = 286) or placebo (N = 291) by subcutaneous injection once monthly for 3 months. Patients were allowed to use acute headache treatments including migraine-specific medications (i.e., triptans, ergotamine derivatives) and NSAIDs during the study.

The study excluded patients with medication overuse headache as well as patients with myocardial infarction, stroke, transient ischemic attacks, unstable angina, coronary artery bypass surgery, or other revascularization procedures within 12 months prior to screening.

The primary efficacy endpoint was the change from baseline in monthly migraine days at month 3. Secondary endpoints included the achievement of a ≥ 50% reduction from baseline in monthly migraine days ("≥ 50% MMD responders"), the change from baseline in monthly acute migraine-specific medication days at month 3, and the proportion of patients with at least a 5-point score reduction from baseline in MPFID at month 3.

A total of 546 (95%) patients completed the 3-month double-blind study. Patients had a median age of 43 years (range: 18 to 65 years), 85% were female, and 90% were white. Six to seven percent of patients were taking concomitant preventive migraine treatment. The mean migraine frequency at baseline was approximately 8 migraine days per month and was similar between treatment groups.

AIMOVIG treatment demonstrated statistically significant improvements for key efficacy endpoints compared to placebo, as summarized in Table 4.

Figure 4 shows the distribution of change from baseline in monthly migraine days at month 3 in bins of 2 days by treatment group. A treatment benefit over placebo for AIMOVIG is seen across a range of changes from baseline in monthly migraine days.

The pre-specified analysis for the MPFID was based on at least a 5-point reduction within-patient responder definition. AIMOVIG 70 mg once monthly was not significantly better than placebo for the proportion of responders for everyday activity [difference from placebo: 4.7%; odds ratio = 1.2; p- value = 0.26] and physical impairment [difference from placebo: 5.9%; odds ratio = 1.3; p- value = 0.13]. In an exploratory analysis of the change from baseline in the mean MPFID scores at month 3, patients treated with AIMOVIG 70 mg, as compared to placebo, showed nominally greater reductions of physical impairment scores [difference from placebo: -1.3; p- value = 0.021], but not of everyday activities scores [difference from placebo: -1.1; p- value = 0.061].

Chronic Migraine

Study 3 (NCT 02066415) was a randomized, multi-center, 3-month, placebo-controlled, double-blind study evaluating AIMOVIG as a preventive treatment of chronic migraine. A total of 667 patients with a history of chronic migraine with or without aura were randomized to receive AIMOVIG 70 mg (N = 191), AIMOVIG 140 mg (N = 190), or placebo (N = 286) by subcutaneous injections once monthly for 3 months. Patients were allowed to use acute headache treatments including migraine-specific medications (i.e., triptans, ergotamine derivatives) and NSAIDs during the study.

The study excluded patients with medication overuse headache caused by opiate overuse and patients with concurrent use of migraine preventive treatments. Patients with myocardial infarction, stroke, transient ischemic attacks, unstable angina, coronary artery bypass surgery, or other revascularization procedures within 12 months prior to screening were also excluded.

The primary efficacy endpoint was the change from baseline in monthly migraine days at month 3. Secondary endpoints included the achievement of a ≥ 50% reduction from baseline in monthly migraine days ("≥ 50% MMD responders") and change from baseline in monthly acute migraine-specific medication days at month 3.

A total of 631 (95%) patients completed the 3-month double-blind study. Patients had a median age of 43 years (range: 18 to 66 years), 83% were female, and 94% were white. The mean migraine frequency at baseline was approximately 18 migraine days per month and was similar across treatment groups.

AIMOVIG treatment demonstrated statistically significant improvements for key efficacy outcomes compared to placebo, as summarized in Table 5.

Figure 6 shows the distribution of change from baseline in monthly migraine days at month 3 in bins of 3 days by treatment group. A treatment benefit over placebo for both doses of AIMOVIG is seen across a range of changes from baseline in migraine days.
