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 [see Clinical Studies (14)]. 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 [see Clinical Studies (14)]. The most common adverse reactions of AJOVY observed in Study 3 were injection site reactions. Hypersensitivity reactions were also observed.

(2.2) 2.1 Recommended Dosage Adults The recommended dosage in adults for the preventive treatment of migraine is administered by subcutaneous injection as one of the following options: 225 mg monthly, or 675 mg every 3 months (quarterly), which is administered as three consecutive subcutaneous injections of 225 mg each. When switching dosage options, administer the first dose of the new regimen on the next scheduled date of administration. Pediatric Patients who are 6 to 17 Years of Age and who Weigh 45 kg or More: The recommended dosage 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 is administered by subcutaneous injection as follows: 225 mg monthly. AJOVY is not approved in pediatric patients weighing less than 45 kg because of the lack of an appropriate strength presentation [see Clinical Studies (14) and How Supplied/Storage and Handling (16.1)]. 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. 2.2 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 [see Instructions for Use]: 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 [see How Supplied/Storage and Handling (16.2)]. Follow aseptic injection technique every time AJOVY is administered. Inspect AJOVY for particles or discoloration prior to administration [see Dosage Forms and Strengths (3)]. 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.

AJOVY has a long half-life [see Clinical Pharmacology (12.3)]. 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 [see Animal Data]. 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).
