Adverse Reactions

6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in other sections of the labeling: Myocardial Ischemia, Myocardial Infarction, and Prinzmetal’s Angina [see Warnings and Precautions ( 5.1 )] Arrhythmias [see Warnings and Precautions ( 5.2 )] Chest, Throat, Neck and/or Jaw Pain/Tightness/Pressure [see Warnings and Precautions ( 5.3 )] Cerebrovascular Events [see Warnings and Precautions ( 5.4 )] Other Vasospasm Reactions [see Warnings and Precautions ( 5.5 )] Medication Overuse Headache [see Warnings and Precautions ( 5.6 )] Serotonin Syndrome [see Warnings and Precautions ( 5.7 )] Increases in Blood Pressure [see Warnings and Precautions ( 5.8 )] Hypersensitivity Reactions [see Contraindications ( 4 ) and Warnings and Precautions ( 5.9 )] Most common adverse reactions (≥2% and >placebo) were dizziness, headache, paresthesia, dry mouth, dyspepsia, fatigue, hot or cold sensation, chest pain, skeletal pain, and flushing ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Par Pharmaceutical at 1-800-462-3636 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 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 practice. Frovatriptan succinate tablets were evaluated in four randomized, double-blind, placebo-controlled, short-term trials. These trials involved 2392 patients (1554 on frovatriptan succinate tablets 2.5 mg and 838 on placebo). In these short-term trials, patients were predominately female (88%) and Caucasian (94%) with a mean age of 42 years (range 18 to 69).The treatment-emergent adverse events that occurred most frequently following administration of frovatriptan succinate tablets 2.5 mg ( i.e., in at least 2% of patients), and at an incidence ≥1% greater than with placebo, were dizziness, paresthesia, headache, dry mouth, fatigue, flushing, hot or cold sensation, dyspepsia, skeletal pain, and chest pain. In a long-term, open-label study where 496 patients were allowed to treat multiple migraine attacks with frovatriptan succinate tablets 2.5 mg for up to 1 year, 5% of patients (n=26) discontinued due to treatment-emergent adverse events. Table 1 lists treatment-emergent adverse events reported within 48 hours of drug administration that occurred with frovatriptan succinate tablets 2.5 mg at an incidence of ≥2% and more often than on placebo, in the four placebo-controlled trials. The events cited reflect experience gained under closely monitored conditions of clinical trials in a highly selected patient population. In actual clinical practice or in other clinical trials, these incidence estimates may not apply, as the conditions of use, reporting behavior, and the kinds of patients treated may differ. Table 1 Adverse Reactions Reported within 48 Hours (Incidence ≥2% and Greater Than Placebo) of Patients in Four Pooled Placebo-Controlled Migraine Trials Adverse Reactions frovatriptan succinate tablets 2.5 mg (n=1554) Placebo (n=838) Central & peripheral nervous system Dizziness Headache Paresthesia 8% 4% 4% 5% 3% 2% Gastrointestinal system disorders Dry mouth Dyspepsia 3% 2% 1% 1% Body as a whole – general disorders Fatigue Hot or cold sensation Chest pain 5% 3% 2% 2% 2% 1% Musculo-skeletal Skeletal pain 3% 2% Vascular Flushing 4% 2% The incidence of adverse events in clinical trials did not increase when up to 3 doses were used within 24 hours. The incidence of adverse events in placebo-controlled clinical trials was not affected by gender, age, or concomitant medications commonly used by migraine patients. There were insufficient data to assess the impact of race on the incidence of adverse events. Other Events Observed in Association with the Administration of frovatriptan succinate tablets The incidence of frequently reported adverse events in four placebo-controlled trials is presented below. Events are further classified within body system categories. Frequent adverse events are those occurring in at least 1/100 patients. Central and peripheral nervous system: dysesthesia and hypoesthesia. Gastrointestinal: vomiting, abdominal pain and diarrhea. Body as a whole: pain. Psychiatric: insomnia and anxiety. Respiratory: sinusitis and rhinitis. Vision disorders : vision abnormal. Skin and appendages: sweating increased. Hearing and vestibular disorders: tinnitus. Heart rate and rhythm: palpitation. 6.2 Postmarketing Experience The following adverse reactions were identified during post approval use of frovatriptan succinate tablets. Because these events 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. Central and peripheral nervous system : Seizure.

Description

11 DESCRIPTION Frovatriptan succinate tablets contain frovatriptan succinate, a selective 5-hydroxy-tryptamine 1 (5-HT 1B/1D ) receptor subtype agonist (triptan), as the active ingredient. Frovatriptan succinate is chemically designated as R-(+) 3-methylamino-6-carboxamido-1,2,3,4-tetrahydrocarbazole monosuccinate monohydrate and it has the following structure: The empirical formula is C 14 H 17 N 3 O.C 4 H 6 O 4 .H 2 O, representing a molecular weight of 379.4. Frovatriptan succinate is a white to off-white powder that is soluble in water. Each frovatriptan succinate tablet for oral administration contains 3.91 mg frovatriptan succinate, equivalent to 2.5 mg of frovatriptan base. Each tablet also contains the inactive ingredients lactose NF, microcrystalline cellulose NF, colloidal silicon dioxide NF, sodium starch glycolate NF, magnesium stearate NF, hypromellose USP, polyethylene glycol 3000 USP, triacetin USP, and titanium dioxide USP. Chemical Structure

Dosage And Administration

2 DOSAGE AND ADMINISTRATION Dosing Information The recommended dose is a single tablet of frovatriptan succinate tablets (frovatriptan 2.5 mg) taken orally with fluids. If the migraine recurs after initial relief, a second tablet may be taken, providing there is an interval of at least 2 hours between doses. The total daily dose of frovatriptan succinate tablets should not exceed 3 tablets (3 x 2.5 mg per 24 hour period). There is no evidence that a second dose of frovatriptan succinate tablets is effective in patients who do not respond to a first dose of the drug for the same headache. The safety of treating an average of more than 4 migraine attacks in a 30-day period has not been established. 1 tablet taken with fluids. Second tablet may be taken 2 hours after initial dose if headache recurs following initial relief. Total dose not to exceed 3 tablets in any 24-hour period ( 2 )

Indications And Usage

1 INDICATIONS AND USAGE Frovatriptan succinate tablets are indicated for the acute treatment of migraine with or without aura in adults. Limitations of Use Use only if a clear diagnosis of migraine has been established. If a patient has no response for the first migraine attack treated with frovatriptan succinate tablets, reconsider the diagnosis of migraine before frovatriptan succinate tablets are administered to treat any subsequent attacks. Frovatriptan succinate tablets are not indicated for the prevention of migraine attacks. Safety and effectiveness of frovatriptan succinate tablets have not been established for cluster headache. Frovatriptan succinate is a serotonin (5-HT 1B/1D ) receptor agonist (triptan) indicated for the acute treatment of migraine with or without aura in adults ( 1 ) Limitations of Use Use only after a clear diagnosis of migraine has been established ( 1 ) Not indicated for the prophylactic therapy of migraine ( 1 ) Not indicated for the treatment of cluster headache ( 1 )

Overdosage

10 OVERDOSAGE The elimination half-life of frovatriptan is 26 hours [ see Clinical Pharmacology ( 12.3 ) ]. Therefore, monitoring of patients after overdose with frovatriptan should continue for at least 48 hours or while symptoms or signs persist. There is no specific antidote to frovatriptan. It is unknown what effect hemodialysis or peritoneal dialysis has on the serum concentrations of frovatriptan.

Drug Interactions

7 DRUG INTERACTIONS 7.1 Ergot-containing Drugs Ergot-containing drugs have been reported to cause prolonged vasospastic reactions. Because these effects may be additive, use of ergotamine-containing or ergot-type medications (like dihydroergotamine or methysergide) and frovatriptan succinate tablets within 24 hours of each other is contraindicated [ see Contraindications ( 4 ) ]. 7.2 5-HT 1B/1D Agonists Because their vasospastic effects may be additive, co-administration of frovatriptan succinate tablets and other 5-HT 1 agonists (e.g., triptans) within 24 hours of each other is contraindicated [ see Contraindications ( 4 ) ]. 7.3 Selective Serotonin Reuptake Inhibitors / Serotonin Norepinephrine Reuptake Inhibitors and Serotonin Syndrome Cases of serotonin syndrome have been reported during combined use of triptans and SSRIs, SNRIs, TCAs, and MAO inhibitors [ see Warnings and Precautions ( 5.7 ) ].

Clinical Pharmacology

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Frovatriptan binds with high affinity to 5-HT 1B/1D receptors. The therapeutic activity of frovatriptan succinate tablets is thought to be due to the agonist effects at the 5-HT 1B/1D receptors on intracranial blood vessels (including the arterio-venous anastomoses) and sensory nerves of the trigeminal system which result in cranial vessel constriction and inhibition of pro-inflammatory neuropeptide release. 12.3 Pharmacokinetics The pharmacokinetics of frovatriptan are similar in migraine patients and healthy subjects. Absorption Mean maximum blood concentrations (C max ) in patients are achieved approximately 2 to 4 hours after administration of a single oral dose of frovatriptan 2.5 mg. The absolute bioavailability of an oral dose of frovatriptan 2.5 mg in healthy subjects is about 20% in males and 30% in females. Food has no significant effect on the bioavailability of frovatriptan, but delays t max by one hour. Distribution Binding of frovatriptan to serum proteins is low (approximately 15%). Reversible binding to blood cells at equilibrium is approximately 60%, resulting in a blood: plasma ratio of about 2:1 in both males and females. The mean steady state volume of distribution of frovatriptan following intravenous administration of 0.8 mg is 4.2 L/kg in males and 3.0 L/kg in females. Metabolism In vitro, cytochrome P450 1A2 appears to be the principal enzyme involved in the metabolism of frovatriptan. Following administration of a single oral dose of radiolabeled frovatriptan 2.5 mg to healthy male and female subjects, 32% of the dose was recovered in urine and 62% in feces. Radiolabeled compounds excreted in urine were unchanged frovatriptan, hydroxylated frovatriptan, N-acetyl desmethyl frovatriptan, hydroxylated N-acetyl desmethyl frovatriptan and desmethyl frovatriptan, together with several other minor metabolites. Desmethyl frovatriptan has lower affinity for 5-HT 1B/1D receptors compared to the parent compound. The N-acetyl desmethyl metabolite has no significant affinity for 5-HT receptors. The activity of the other metabolites is unknown. Elimination After an intravenous dose, mean clearance of frovatriptan was 220 and 130 mL/min in males and females, respectively. Renal clearance accounted for about 40% (82 mL/min) and 45% (60 mL/min) of total clearance in males and females, respectively. The mean terminal elimination half-life of frovatriptan in both males and females is approximately 26 hours. Special Populations Hepatic Impairment The AUC of frovatriptan in patients with mild (Child-Pugh 5-6) to moderate (Child-Pugh 7-9) hepatic impairment was about twice that of young, healthy subjects, but within the range observed in healthy elderly subjects and was considerably lower than the values attained with higher doses of frovatriptan (up to 40 mg), which were not associated with any serious adverse effects . There is no clinical or pharmacokinetic experience with frovatriptan succinate tablets in patients with severe hepatic impairment. Renal Impairment The pharmacokinetics of frovatriptan following a single oral dose of 2.5 mg was not different in patients with renal impairment (5 males and 6 females, creatinine clearance 16 - 73 mL/min) compared to subjects with normal renal function. Age Mean AUC of frovatriptan was 1.5- to 2-fold higher in healthy elderly subjects (age 65 to 77 years) compared to those in healthy younger subjects (age 21 to 37 years). There was no difference in t max or t 1/2 between the two populations. Sex There was no difference in the mean terminal elimination half-life of frovatriptan in males and females. Bioavailability was higher, and systemic exposure to frovatriptan was approximately 2-fold greater, in females than males, irrespective of age. Race The effect of race on the pharmacokinetics of frovatriptan has not been examined. Drug Interaction Studies Frovatriptan is not an inhibitor of human monoamine oxidase (MAO) enzymes or cytochrome P450 (isozymes 1A2, 2C9, 2C19, 2D6, 2E1, 3A4) in vitro at concentrations up to 250 to 500- fold higher than the highest blood concentrations observed in man at a dose of 2.5 mg. No induction of drug metabolizing enzymes was observed following multiple dosing of frovatriptan to rats or on addition to human hepatocytes in vitro . Although no clinical trials have been performed, it is unlikely that frovatriptan will affect the metabolism of co-administered drugs metabolized by these mechanisms. Oral Contraceptives Retrospective analysis of pharmacokinetic data from females across trials indicated that the mean C max and AUC of frovatriptan are 30% higher in those subjects taking oral contraceptives compared to those not taking oral contraceptives. Ergotamine The AUC and C max of frovatriptan (2 x 2.5 mg dose) were reduced by approximately 25% when co-administered with ergotamine tartrate [see Contraindications ( 4 ), Drug Interactions ( 7.1 )] . Propranolol Propranolol increased the AUC of frovatriptan 2.5 mg in males by 60% and in females by 29%. The C max of frovatriptan was increased 23% in males and 16% in females in the presence of propranolol. The t max as well as half-life of frovatriptan, though slightly longer in the females, were not affected by concomitant administration of propranolol. Moclobemide The pharmacokinetic profile of frovatriptan was unaffected when a single oral dose of frovatriptan 2.5 mg was administered to healthy female subjects receiving the MAO-A inhibitor, moclobemide, at an oral dose of 150 mg twice a day for 8 days.

12.1 Mechanism of Action Frovatriptan binds with high affinity to 5-HT 1B/1D receptors.

Carcinogenesis And Mutagenesis And Impairment Of Fertility

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis The carcinogenic potential of orally administered frovatriptan was evaluated in an 84-week study in mice (4, 13, and 40 mg/kg/day), a 104-week study in rats (8.5, 27, and 85 mg/kg/day), and a 26-week study in p53(+/-) transgenic mice (20, 62.5, 200, and 400 mg/kg/day). Although a maximum tolerated dose was not achieved in the 84-week mouse study and in female rats, plasma exposures at the highest doses studied were higher than that achieved in humans at the MRHD of 7.5 mg/day. There were no increases in tumor incidence in the 84-week mouse study at doses producing plasma exposures (AUC) 140 times that in humans at the MRHD. In the rat study, there was a statistically significant increase in the incidence of pituitary adenomas in males only at 85 mg/kg/day, a dose associated with a plasma AUC 250 times that in humans at the MRHD. In the 26-week p53(+/-) transgenic mouse study, the incidence of subcutaneous sarcomas was increased in females at doses of 200 and 400 mg/kg/day. These sarcomas were associated with subcutaneously implanted animal identification transponders, and are not considered to be relevant to humans. There were no other increases in tumor incidence of any type in any dose group. Mutagenesis Frovatriptan was clastogenic in human lymphocyte cultures, in the absence of metabolic activation. In the bacterial reverse mutation assay (Ames test), frovatriptan produced an equivocal response in the absence of metabolic activation. Frovatriptan was negative in an in vitro mouse lymphoma tk assay and an in vivo mouse bone marrow micronucleus test. Impairment of Fertility Male and female rats were dosed orally with frovatriptan prior to and during mating and in females up to implantation, at doses of 100, 500, and 1000 mg/kg/day (equivalent to approximately 130, 650, and 1300 times the MRHD on a mg/m 2 basis). At all dose levels, there was an increase in the number of females that mated on the first day of pairing compared to control animals. This occurred in conjunction with a prolongation of the estrous cycle. In addition, females had a decreased mean number of corpora lutea, and consequently a lower number of live fetuses per litter, which suggested a partial impairment of ovulation. There were no other fertility-related effects.

    Clinical Studies

    14 CLINICAL STUDIES The efficacy of frovatriptan succinate tablets in the acute treatment of migraine headaches was demonstrated in four randomized, double-blind, placebo-controlled, short-term outpatient trials. In these trials, patients received doses of frovatriptan from 0.5 mg to 40 mg. In these controlled short-term trials, patients were predominately female (88%) and Caucasian (94%) with a mean age of 42 years (range 18 to 69). Patients were instructed to treat a moderate to severe headache. Headache response, defined as a reduction in headache severity from moderate or severe pain to mild or no pain, was assessed for up to 24 hours after dosing. The associated symptoms nausea, vomiting, photophobia and phonophobia, were also assessed. Maintenance of response was assessed for up to 24 hours post dose. In two of the trials a second dose of frovatriptan succinate tablets was provided after the initial treatment, to treat recurrence of the headache within 24 hours. Other medication, excluding other 5-HT 1 agonists and ergotamine containing compounds, was permitted from 2 hours after the first dose of frovatriptan succinate tablets. The frequency and time to use of additional medications were also recorded. In all four placebo-controlled trials, the percentage of patients achieving a headache response 2 hours after treatment was significantly greater for those taking frovatriptan succinate tablets 2.5 mg compared to those taking placebo (Table 2). Lower doses of frovatriptan (1 mg or 0.5 mg) were not effective at 2 hours. Higher doses (5 mg to 40 mg) of frovatriptan showed no added benefit over 2.5 mg but did cause a greater incidence of adverse events. Table 2 Percentage of Patients with Headache Response (Mild or No Headache) 2 Hours Following Treatment a Trial frovatriptan succinate tablets 2.5 mg Placebo 1 42%* (n=90) 22% (n=91) 2 39%* (n=187) 21% (n=99) 3 46%** (n=672) 27% (n=347) 4 37%** (n=438) 23% (n=225) a ITT observed data, excludes patients who had missing data or were asleep. *p<0.05. **p<0.001 in comparison with placebo. The estimated probability of achieving an initial headache response by 2 hours following treatment is depicted in Figure 1. Figure 1 Estimated Probability of Achieving Initial Headache Response Within 2 Hours Figure 1 shows a Kaplan-Meier plot of the probability over time of obtaining headache response (no or mild pain) following treatment with frovatriptan succinate tablets 2.5 mg or placebo. The probabilities displayed are based on pooled data from the four placebo-controlled trials described in Table 2. Patients who did not achieve a response were censored at 24 hours. In patients with migraine-associated nausea, photophobia, and phonophobia at baseline there was a decreased incidence of these symptoms in frovatriptan succinate tablets treated patients compared to placebo. The estimated probability of patients taking a second dose or other medication for their migraine over the 24 hours following the initial dose of study treatment is summarized in Figure 2. Figure 2 Estimated Probability of Patients Taking a Second Dose or Other Medication for Migraine Over the 24 Hours Following the Initial Dose of Study Treatment Figure 2 is a Kaplan-Meier plot showing the probability of patients taking a second dose or other medication for migraine over the 24 hours following the initial dose of study medication based on the data from the four placebo-controlled trials described in Table 2. The plot includes those patients who had a response to the initial dose and those who did not. The protocols did not permit remedication within 2 hours of the initial dose. Efficacy was unaffected by a history of aura; gender; age, or concomitant medications commonly used by migraine patients. Figure 1 Figure 2

    Geriatric Use

    8.5 Geriatric Use Mean blood concentrations of frovatriptan in elderly patients were 1.5- to 2-times higher than those seen in younger adults [ see Clinical Pharmacology ( 12.3 ) ]. No dosage adjustment is necessary.

    Nursing Mothers

    8.2 Lactation Risk Summary There are no data on the presence of frovatriptan in human milk, the effects of frovatriptan on the breastfed infant, or the effects of frovatriptan on milk production. In rats, oral dosing with frovatriptan resulted in levels of frovatriptan and/or its metabolites in milk up to four times higher than in plasma. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for frovatriptan succinate tablets and any potential adverse effects on the breastfed infant from frovatriptan or from the underlying maternal condition.

    Pediatric Use

    8.4 Pediatric Use The safety and effectiveness in pediatric patients have not been established. Therefore, frovatriptan succinate tablets are not recommended for use in patients under 18 years of age. There are no additional adverse reactions identified in pediatric patients based on postmarketing experience that were not previously identified in adults.

    Pregnancy

    8.1 Pregnancy Risk Summary There are no adequate data on the developmental risk associated with the use of frovatriptan succinate tablets in pregnant women. In animal studies, frovatriptan produced developmental toxicity (embryofetal lethality, fetal abnormalities, and decreased embryofetal growth) when administered to pregnant rats and rabbits at doses greater than those used clinically [see Animal Data] . In the U.S. general population, the estimated background risk of major birth defects and of miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. The reported rate of major birth defects among deliveries to women with migraine ranged from 2.2% to 2.9% and the reported rate of miscarriage was 17%, which were 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 migraines may be at increased risk of preeclampsia during pregnancy. Data Animal Data When pregnant rats were administered frovatriptan (oral doses of 0, 100, 500, or 1000 mg/kg/day) throughout organogenesis, increased embryofetal mortality and an increased incidence of fetal malformations were observed at the high dose; decreased fetal body weights and increased incidences of fetal structural variations associated with growth impairment were observed at all doses. The lowest effect dose for embryofetal developmental toxicity in rats (100 mg/kg/day) is approximately 130 times the maximum recommended human dose (MRHD) of 7.5 mg/day on a body surface area (mg/m 2 ) basis. When pregnant rabbits were administered frovatriptan (oral doses of 0, 5, 20, or 80 mg/kg/day) throughout organogenesis, embryofetal mortality was increased at the mid and high doses. The no-effect dose for embryofetal developmental toxicity in rabbits (5 mg/kg/day) is approximately 13 times the MRHD on a mg/m 2 basis. Oral administration of frovatriptan (0, 100, 500, or 1000 mg/kg/day) to female rats throughout pregnancy and lactation resulted in increased embryofetal mortality at the high dose. The no effect dose for pre- and postnatal developmental toxicity in rats (500 mg/kg/day) is approximately 650 times the MRHD on a mg/m 2 basis.

    Use In Specific Populations

    8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm ( 8.1 ) 8.1 Pregnancy Risk Summary There are no adequate data on the developmental risk associated with the use of frovatriptan succinate tablets in pregnant women.

No dosage adjustment is necessary. 8.6 Patients with Hepatic Impairment No dosage adjustment is necessary when frovatriptan succinate tablets are given to patients with mild to moderate hepatic impairment. There is no clinical or pharmacokinetic experience with frovatriptan succinate tablets in patients with severe hepatic impairment. Because a greater than two-fold increase in AUC is predicted in patients with severe hepatic impairment, there is a greater potential for adverse events in these patients, and frovatriptan succinate tablets should therefore be used with caution in that population.
