AJOVY is not approved in pediatric patients weighing less than 45 kg because of the lack of an appropriate strength presentation . Missed Dose If a dose of AJOVY is missed, administer as soon as possible. Thereafter, AJOVY can be scheduled from the date of the last dose.
Important
Administration Instructions AJOVY is for subcutaneous use only. AJOVY may be administered by healthcare providers, patients 13 years of age and older, and/or caregivers. In pediatric patients 6 to 12 years of age, AJOVY must be administered by a healthcare provider or adult caregiver.
Prior to use, provide proper training to patients and/or caregivers on the preparation and administration of AJOVY prefilled syringe, including aseptic technique : Remove AJOVY from the refrigerator. Prior to use, allow AJOVY to sit at room temperature for 30 minutes protected from direct sunlight. Do not warm by using a heat source such as hot water or a microwave.
Do not use AJOVY if it has been at room temperature for 7 days or longer. Follow aseptic injection technique every time AJOVY is administered. Inspect AJOVY for particles or discoloration prior to administration . Do not use if the solution is cloudy, discolored, or contains particles.
Administer AJOVY by subcutaneous injection into areas of the abdomen, thigh, or upper arm that are not tender, bruised, red, or indurated. For multiple injections, you may use the same body site, but not the exact location of the previous injection. Do not co-administer AJOVY with other injectable drugs at the same injection site.
Side Effects of Ajovy
Clinical Trials Experience
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. Adults The safety of AJOVY was evaluated in 2512 patients with migraine who received at least 1 dose of AJOVY, representing 1279 patient-years of exposure. Of these, 1730 patients were exposed to AJOVY 225 mg monthly or AJOVY 675 mg quarterly for at least 6 months, 775 patients for at least 12 months, and 138 patients for at least 15 months.
In placebo-controlled clinical trials (Studies 1 and 2), 662 patients received AJOVY 225 mg monthly for 12 weeks (with or without a loading dose of 675 mg), and 663 patients received AJOVY 675 mg quarterly for 12 weeks . In the controlled trials, 87% of patients were female, 80% were White, and the mean age was 41 years. The most common adverse reactions in the clinical trials for the preventive treatment of migraine (incidence at least 5% and greater than placebo) were injection site reactions. The adverse reactions that most commonly led to discontinuations were injection site reactions (1%). Table 1 summarizes adverse reactions reported in the 3-month placebo-controlled studies (Study 1 and Study 2), and the 1-month follow-up period after those studies.

Pediatric Patients 6 to 17 Years of Age The safety of AJOVY was evaluated in 225 pediatric patients 6 to 17 years of age with episodic migraine who received at least one dose of AJOVY. Of these patients, 209 received AJOVY monthly for at least 6 months and 100 received AJOVY for at least 12 months. In the placebo-controlled trial (Study 3), 123 pediatric patients with episodic migraine were treated with AJOVY . The most common adverse reactions of AJOVY observed in Study 3 were injection site reactions.
Hypersensitivity reactions were also observed. Overall, the safety profile in pediatric patients is similar to the known safety profile in adults.
Postmarketing Experience
The following adverse reactions have been identified during postapproval use of AJOVY. 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 : Anaphylactic reactions and angioedema Vascular Disorders : Hypertension , Raynaud’s phenomenon
Warnings & Cautions for Ajovy
Hypersensitivity Reactions Hypersensitivity reactions, including rash, pruritus, drug hypersensitivity, and urticaria, were
reported with AJOVY in clinical trials. Most reactions were mild to moderate, but some led to discontinuation or required corticosteroid treatment. Most reactions were reported from within hours to one month after administration.
Cases of anaphylaxis and angioedema have been reported in the postmarketing setting. If a hypersensitivity reaction occurs, consider discontinuing AJOVY, and institute appropriate therapy .
Hypertension Development of hypertension and worsening of pre-existing hypertension have been reported
following the use of CGRP antagonists, including AJOVY, in the postmarketing setting. Some of the patients who developed new-onset hypertension had risk factors for hypertension. There were cases requiring initiation of pharmacological treatment for hypertension and, in some cases, hospitalization.
Hypertension may occur at any time during treatment, but was most frequently reported within 7 days of therapy initiation. AJOVY was discontinued in many of the reported cases. Monitor patients treated with AJOVY for new-onset hypertension or worsening of pre-existing hypertension, and consider whether discontinuation of AJOVY is warranted if evaluation fails to establish an alternative etiology or blood pressure is inadequately controlled.
Raynaud's Phenomenon 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 AJOVY. 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.
AJOVY 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.
Pregnancy Safety for Ajovy
Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to AJOVY during pregnancy. Healthcare providers are encouraged to register pregnant patients, or pregnant women may enroll themselves in the registry by calling 1-833-927-2605 or visiting www.tevamigrainepregnancyregistry.com. Risk Summary There are no adequate data on the developmental risk associated with the use of AJOVY in pregnant women.
AJOVY has a long half-life . This should be taken into consideration for women who are pregnant or plan to become pregnant while using AJOVY. Administration of fremanezumab-vfrm to rats and rabbits during the period of organogenesis or to rats throughout pregnancy and lactation at doses resulting in plasma levels greater than those expected clinically did not result in adverse effects on development . In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The estimated rate of major birth defects (2.2-2.9%) and miscarriage (17%) among deliveries to women with migraine are similar to rates reported in women without migraine. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Published data have suggested that women with migraine may be at increased risk of preeclampsia and gestational hypertension during pregnancy.
Data Animal Data When fremanezumab-vfrm (0, 50, 100, or 200 mg/kg) was administered to male and female rats by weekly subcutaneous injection prior to and during mating and continuing in females throughout organogenesis, no adverse embryofetal effects were observed. The highest dose tested was associated with plasma exposures (AUC) approximately 2 times that in humans at a dose of 675 mg. Administration of fremanezumab-vfrm (0, 10, 50, or 100 mg/kg) weekly by subcutaneous injection to pregnant rabbits throughout the period of organogenesis produced no adverse effects on embryofetal development.
The highest dose tested was associated with plasma AUC approximately 3 times that in humans (675 mg). Administration of fremanezumab-vfrm (0, 50, 100, or 200 mg/kg) weekly by subcutaneous injection to female rats throughout pregnancy and lactation resulted in no adverse effects on pre- and postnatal development. The highest dose tested was associated with plasma AUC approximately 2 times that in humans (675 mg).
Pediatric Use of Ajovy
Pediatric Use Episodic Migraine The safety and effectiveness of AJOVY have been established in an adequate and well-controlled study for the preventive treatment of episodic migraine in pediatric patients who are 6 to 17 years of age and who weigh 45 kg or more (Study 3). The safety and efficacy profile of AJOVY in these patients was similar to the safety and efficacy profile seen in clinical trials in adults with migraine. AJOVY is not approved in pediatric patients weighing less than 45 kg because of the lack of an appropriate strength presentation. The safety and effectiveness of AJOVY for the preventive treatment of episodic migraine in pediatric patients younger than 6 years of age have not been established.
Chronic Migraine The safety and effectiveness of AJOVY for the preventive treatment of chronic migraine in pediatric patients have not been established. Juvenile Animal Toxicity Data Subcutaneous administration of fremanezumab-vfrm (0, 50, 150, or 450 mg/kg) to juvenile rats once weekly from postnatal day (PND) 28 to PND 63 resulted in no adverse effects on growth, sexual maturation, or neurobehavioral or reproductive function. The highest dose tested was associated with plasma drug exposures (AUC) approximately 58 times that in pediatric patients at the recommended human dose (225 mg), when calculated on a monthly basis.
Contraindications for Ajovy
is contraindicated in patients with serious hypersensitivity to fremanezumab-vfrm or to any of the excipients. Reactions have included anaphylaxis and angioedema. AJOVY is contraindicated in patients with serious hypersensitivity to fremanezumab-vfrm or to any of the excipients.

Figure 2: Distribution of Change from Baseline in Mean Monthly Migraine Days by Treatment Group in Study 1 Chronic Migraine Study 2 (NCT 02621931) included adults with a history of chronic migraine (patients with ≥15 headache days per month). All patients were randomized (1:1:1) to receive subcutaneous injections of either AJOVY 675 mg starting dose followed by 225 mg monthly, 675 mg every 3 months (quarterly), or placebo monthly, over a 3-month treatment period. Patients were allowed to use acute headache treatments during the study.
A subset of patients (21%) was allowed to use one additional concomitant, preventive medication. The study excluded patients with a history of significant cardiovascular disease, vascular ischemia, or thrombotic events, such as cerebrovascular accident, transient ischemic attacks, deep vein thrombosis, or pulmonary embolism. The primary efficacy endpoint was the mean change from baseline in the monthly average number of headache days of at least moderate severity during the 3-month treatment period.
The secondary endpoints were the mean change from baseline in the monthly average number of migraine days during the 3-month treatment period, the proportion of patients reaching at least 50% reduction in the monthly average number of headache days of at least moderate severity during the 3-month treatment period, the mean change from baseline in the monthly average number of days of use of any acute headache medication during the 3-month treatment period, and the mean change from baseline in the number of headache days of at least moderate severity during the first month of treatment. In Study 2, a total of 1130 patients (991 females, 139 males), ranging in age from 18 to 70 years, were randomized. A total of 1034 patients completed the 3-month double-blind phase.
Both monthly and quarterly dosing regimens of AJOVY treatment demonstrated statistically significant improvement for key efficacy outcomes compared to placebo, as summarized in Table 4.

Pediatric Patients 6 to 17 Years of Age The efficacy of AJOVY for the preventive treatment of episodic migraine in pediatric patients 6 to 17 years of age was evaluated in a multicenter, randomized, 3-month, double-blind, placebo-controlled study (Study 3). Episodic Migraine Study 3 (NCT 04458857) included pediatric patients 6 to 17 years of age with a history of episodic migraine (patients with <15 headache days per month). All patients were randomized (1:1) to receive monthly subcutaneous injections of either AJOVY or placebo, over a 3-month period. Patients who weighed 45 kg or more received AJOVY 225 mg and patients who weighed under 45 kg received AJOVY 120 mg . Patients were allowed to use acute headache treatments during the study.
A subset of patients (21%) was allowed to use up to two additional concomitant preventive medications. The study excluded patients with clinically significant cardiovascular disease. The primary efficacy endpoint was the mean change from baseline in the monthly average number of migraine days during the 3-month treatment period.
Secondary endpoints included the proportion of patients reaching at least a 50% reduction in monthly average number of migraine days during the 3-month treatment period; the mean change from baseline in the monthly average number of days of use of any acute headache medication during the 3-month treatment period; and the mean change from baseline in monthly average number of headache days of at least moderate severity during the 3-month treatment period. In Study 3, a total of 235 patients (130 females, 105 males) were randomized. A total of 225 patients completed the 3-month, double-blind treatment period.
AJOVY demonstrated statistically significant improvements for efficacy endpoints compared to placebo over the 3-month period, as summarized in Table 5.
