For Healthcare Providers >

Patient Information

Advise the patient to read the FDA approved patient labeling (Patient Information).

Myocardial Ischemia and/or Infarction, Prinzmetal s Angina, Other Vasospastic Reactions, and Cerebrovascular Events

Inform patients that FROVA may cause serious cardiovascular adverse reactions such as myocardial infarction or stroke, which may result in hospitalization and even death. Although serious cardiovascular reactions can occur without warning symptoms, instruct patients to be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and instruct them to ask for medical advice when observing any indicative sign or symptoms. Instruct patients to seek medical advice if they have symptoms of other vasospastic reactions[see Warnings and Precautions (5.1,5.2,5.4,5.5, and5.8)].

Hypersensitivity Reactions

Inform patients that anaphylactic reactions have occurred in patients receiving FROVA. Inform patients that such reactions can be life threatening or fatal and to seek immediate medical attention if they have anaphylactic symptoms. In general, anaphylactic reactions to drugs are more likely to occur in individuals with a history of sensitivity to multiple allergens[see Contraindications (4)].

Medication Overuse Headache

Inform patients that use of drugs to treat acute migraines for 10 or more days per month may lead to an exacerbation of headache, and encourage patients to record headache frequency and drug use (e.g., by keeping a headache diary)[see Warnings and Precautions (5.6)].

Serotonin Syndrome

Inform patients about the risk of serotonin syndrome with the use of FROVA or other triptans, particularly during combined use with SSRIs, SNRIs, TCAs, and MAO inhibitors[see Warnings and Precautions (5.7) and Drug Interactions (7.3)].

Pregnancy

Advise patients to notify their healthcare provider if they become pregnant during treatment or plan to become pregnant[see Use in Specific Populations (8.1)].

Lactation

Inform patients to notify their healthcare provider if they are breastfeeding or plan to breastfeed[see Use in Specific Populations (8.2)].

Description ⮝

FROVA (frovatriptan succinate) tablets contain frovatriptan succinate, a selective 5-hydroxy-tryptamine1 (5-HT1B/1D) receptor subtype agonist, 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 C14H17N3O.C4H6O4.H2O, representing a molecular weight of 379.4. Frovatriptan succinate is a white to off-white powder that is soluble in water. Each FROVA 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, hydroxypropylmethylcellulose USP, polyethylene glycol 3000 USP, triacetin USP, and titanium dioxide USP.

Clinical Pharmacology ⮝

Mechanism of Action

Frovatriptan is a 5-HT receptor agonist that binds with high affinity for 5-HT1B and 5-HT1D receptors. Frovatriptan has no significant effects on GABAA mediated channel activity and has no significant affinity for benzodiazepine binding sites.

Frovatriptan is believed to act on extracerebral, intracranial arteries and to inhibit excessive dilation of these vessels in migraine. In anesthetized dogs and cats, intravenous administration of frovatriptan produced selective constriction of the carotid vascular bed and had no effect on blood pressure (both species) or coronary resistance (in dogs).

Pharmacokinetics

Mean maximum blood concentrations (Cmax) in patients are achieved approximately 2 - 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 tmax by one hour.

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.

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-HT1B/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.

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.

The pharmacokinetics of frovatriptan are similar in migraine patients and healthy subjects.

Special Populations

Age:

Mean AUC of frovatriptan was 1.5- to 2-fold higher in healthy elderly subjects (age 65 77 years) compared to those in healthy younger subjects (age 21 - 37 years). There was no difference in tmax or t1/2 between the two populations.

Gender:

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.

Renal Impairment:

Since less than 10% of FROVA is excreted in urine after an oral dose, it is unlikely that the exposure to frovatriptan will be affected by 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) and in subjects with normal renal function.

Hepatic Impairment:

There is no clinical or pharmacokinetic experience with FROVA in patients with severe hepatic impairment. The AUC in subjects with mild (Child-Pugh 5 - 6) to moderate (Child-Pugh 7 - 9) hepatic impairment is about twice as high as the AUC in young, healthy subjects, but within the range found among normal elderly subjects.

Race:

The effect of race on the pharmacokinetics of frovatriptan has not been examined.

Drug Interactions (see also PRECAUTIONS, Drug Interactions)

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 studies 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 Cmax and AUC of frovatriptan are 30% higher in those subjects taking oral contraceptives compared to those not taking oral contraceptives.

Ergotamine:

The AUC and Cmax of frovatriptan (2 x 2.5 mg dose) were reduced by approximately 25% when co-administered with ergotamine tartrate.

Propranolol:

Propranolol increased the AUC of frovatriptan 2.5 mg in males by 60% and in females by 29%. The Cmax of frovatriptan was increased 23% in males and 16% in females in the presence of propranolol. The tmax 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 bid for 8 days.

Clinical Trials

The efficacy of FROVA in the acute treatment of migraine headaches was demonstrated in five randomized, double-blind, placebo-controlled, outpatient trials. Two of these were dose-finding studies in which patients were randomized to receive doses of frovatriptan ranging from 0.5 - 40 mg. The three studies evaluating only one dose studied 2.5 mg. In these controlled short-term studies combined, patients were predominately female (88%) and Caucasian (94%) with a mean age of 42 years (range 18 - 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 FROVA was provided after the initial treatment, to treat recurrence of the headache within 24 hours. Other medication, excluding other 5-HT1 agonists and ergotamine containing compounds, was permitted from 2 hours after the first dose of FROVA. The frequency and time to use of additional medications were also recorded.

In all five placebo-controlled trials, the percentage of patients achieving a headache response 2 hours after treatment was significantly greater for those taking FROVA compared to those taking placebo (Table 1).

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.

Comparisons of drug performance based upon results obtained in different clinical trials are never reliable. Because trials are conducted at different times, with different samples of patients, by different investigators, employing different criteria and/or different interpretations of the same criteria, under different conditions (dose, dosing regimen, etc.), quantitative estimates of treatment response and the timing of response may be expected to vary considerably from study to study.

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 2.5 mg or placebo. The probabilities displayed are based on pooled data from four placebo-controlled trials described in Table 1(Trials 1, 3, 4 and 5). 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 FROVA 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 four placebo-controlled trials described in Table 1 (Trials 1, 3, 4 and 5). 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 FROVA.

Warnings ⮝

FROVA should only be used where a clear diagnosis of migraine has been established.

Risk of Myocardial Ischemia and/or Infarction and Other Adverse Cardiac Events:

Because of the potential of this class of compound (5-HT1 agonists) to cause coronary vasospasm, frovatriptan should not be given to patients with documented ischemic or vasospastic coronary artery disease (CAD) (see CONTRAINDICATIONS). It is strongly recommended that frovatriptan not be given to patients in whom unrecognized CAD is predicted by the presence of risk factors (e.g., hypertension, hypercholesterolemia, smoker, obesity, diabetes, strong family history of CAD, female with surgical or physiological menopause, or male over 40 years of age) unless a cardiovascular evaluation provides satisfactory clinical evidence that the patient is reasonably free of coronary artery and ischemic myocardial disease or other significant underlying cardiovascular disease. The sensitivity of cardiac diagnostic procedures to detect cardiovascular disease or predisposition to coronary artery vasospasm is modest, at best. If, during the cardiovascular evaluation, the patient s medical history, electrocardiographic, or other investigations reveal findings indicative of, or consistent with, coronary artery vasospasm or myocardial ischemia, frovatriptan should not be administered (see CONTRAINDICATIONS).

For patients with risk factors predictive of CAD, who are determined to have a satisfactory cardiovascular evaluation, it is strongly recommended that administration of the first dose of frovatriptan take place in the setting of a physician s office or similar medically staffed and equipped facility unless the patient has previously received frovatriptan. Because cardiac ischemia can occur in the absence of clinical symptoms, consideration should be given to obtaining on the first occasion of use an electrocardiogram (ECG) during the interval immediately following administration of FROVA in these patients with risk factors.

It is recommended that patients who are intermittent long-term users of 5-HT1 agonists, including FROVA and who have or acquire risk factors predictive of CAD, as described above, undergo periodic cardiovascular evaluation as they continue to use FROVA.

The systematic approach described above is intended to reduce the likelihood that patients with unrecognized cardiovascular disease would be inadvertently exposed to frovatriptan.

Cardiac Events and Fatalities with 5-HT1 Agonists:

Serious adverse cardiac events, including acute myocardial infarction, life-threatening disturbances of cardiac rhythm and death have been reported within a few hours of administration of 5-HT1 agonists. Considering the extent of use of 5-HT1 agonists in patients with migraine, the incidence of these events is extremely low.

Premarketing experience with frovatriptan:

Among more than 3000 patients with migraine who participated in premarketing clinical trials of FROVA no deaths or serious cardiac events were reported which were related to the use of FROVA.

Cerebrovascular Events and Fatalities with 5-HT1 Agonists:

Cerebral hemorrhage, subarachnoid hemorrhage, stroke and other cerebrovascular events have been reported in patients treated with 5-HT1 agonists; and some have resulted in fatalities. In a number of cases, it appears possible that the cerebrovascular events were primary, the agonist having been administered in the incorrect belief that the symptoms experienced were a consequence of migraine, when they were not. It should be noted that patients with migraine may be at increased risk of certain cerebrovascular events (e.g. stroke, hemorrhage, transient ischemic attack).

Other Vasospasm-Related Events:

5-HT1 agonists may cause vasospastic reactions other than coronary artery spasm. Both peripheral vascular ischemia and colonic ischemia with abdominal pain and bloody diarrhea have been reported with 5-HT1 agonists.

Effects on Blood Pressure:

In young healthy subjects, there were statistically significant increases in systolic and diastolic blood pressure after single doses of 80 mg frovatriptan (32 times the clinical dose) and above. These increases were transient, resolved spontaneously and were not clinically significant. At the recommended dose of 2.5 mg, transient changes in systolic blood pressure were recorded in some elderly subjects (65 - 77 years). Any increases were generally small, resolved spontaneously, and blood pressure remained within the normal range. Frovatriptan is contraindicated in patients with uncontrolled hypertension (see CONTRAINDICATIONS).

An 18% increase in mean pulmonary artery pressure was seen following dosing with another 5-HT1 agonist in a study evaluating subjects undergoing cardiac catheterization.

Serotonin Syndrome:

The development of a potentially life-threatening serotonin syndrome may occur with triptans, including FROVA treatment, particularly during combined use with selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs). If concomitant treatment with FROVA and an SSRI (e.g., fluoxetine, paroxetine, sertraline, fluvoxamine, citalopram, escitalopram) or SNRI (e.g., venlafaxine, duloxetine) is clinically warranted, careful observation of the patient is advised, particularly during treatment initiation and dose increases. Serotonin syndrome symptoms may include mental status changes (e.g., agitation hallucinations, coma), autonomic instability (e.g., tachycardia, labile blood pressure, hyperthermia), neuromuscular aberrations (e.g., hyperreflexia, incoordination) and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). (See PRECAUTIONS Drug Interactions).

Precautions ⮝

General:

As with other 5-HT1 agonists, sensations of pain, tightness, pressure and heaviness have been reported in the chest, throat, neck and jaw after treatment with FROVA. These events have not been associated with arrhythmias or ischemic ECG changes in clinical trials with FROVA. Because 5-HT1 agonists may cause coronary vasospasm, patients who experience signs or symptoms suggestive of angina following dosing should be evaluated for the presence of CAD. Patients shown to have CAD and those with Prinzmetal s variant angina should not receive 5-HT1 agonists (see CONTRAINDICATIONS). Patients who experience other symptoms or signs suggestive of decreased arterial flow, such as ischemic bowel syndrome or Raynaud s syndrome following the use of any 5-HT1 agonist are candidates for further evaluation. If a patient has no response for the first migraine attack treated with FROVA, the diagnosis of migraine should be reconsidered before frovatriptan is administered to treat any subsequent attacks.

Hepatically Impaired Patients:

There is no clinical or pharmacokinetic experience with FROVA in patients with severe 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. Therefore, no dosage adjustment is necessary when FROVA is given to patients with mild to moderate hepatic impairment (see CLINICAL PHARMACOLOGY, Special Populations).

Binding to Melanin-Containing Tissues:

When pigmented rats were given a single oral dose of 5 mg/kg of radiolabeled frovatriptan, the radioactivity in the eye after 28 days was 87% of the value measured after 8 hours. This suggests that frovatriptan and/or its metabolites may bind to the melanin of the eye. Because there could be accumulation in melanin rich tissues over time, this raises the possibility that frovatriptan could cause toxicity in these tissues after extended use. However, no effects on the retina related to treatment with frovatriptan were noted in the toxicity studies. Although no systematic monitoring of ophthalmologic function was undertaken in clinical trials and no specific recommendations for ophthalmologic monitoring are made, prescribers should be aware of the possibility of long-term ophthalmologic effects.

Information for Patients

Physicians should instruct their patients to read the patient package insert before taking FROVA. See PATIENT INFORMATION at the end of this labeling for the text of the separate leaflet provided for patients.

Patients should be cautioned about the risk of serotonin syndrome with the use of FROVA or other triptans, especially during combined use with selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs).

Laboratory Tests

No specific laboratory tests are recommended for monitoring patients prior to and/or after treatment with FROVA.

Drug Interactions (see also CLINICAL PHARMACOLOGY, Drug Interactions)

Ergot-containing drugs have been reported to cause prolonged vasospastic reactions. Due to a theoretical risk of a pharmacodynamic interaction, use of ergotamine-containing or ergot-type medications (like dihydroergotamine or methysergide) and FROVA within 24 hours of each other should be avoided (see CONTRAINDICATIONS).

Concomitant use of other 5HT1B/1D agonists within 24 hours of FROVA treatment is not recommended (see CONTRAINDICATIONS).

Selective Serotonin Reuptake Inhibitors / Serotonin Norepinephrine Reuptake Inhibitors and Serotonin Syndrome: Cases of life-threatening serotonin syndrome have been reported during combined use of selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) and triptans. (See WARNINGS).

Drug/Laboratory Test Interactions

FROVA is not known to interfere with commonly employed clinical laboratory tests.

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis: The carcinogenic potential of 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 the maximum tolerated dose (MTD) was not achieved in the 84-week mouse study and in female rats, exposures at the highest doses studied were many fold greater than those achieved at the maximum recommended daily human dose (MRHD) of 7.5 mg. There were no increases in tumor incidence in the 84-week mouse study at doses producing 140 times the exposure achieved at the MRHD based on blood AUC comparisons. 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 that produced 250 times the exposure achieved at the MRHD based on AUC comparisons. In the 26-week p53(+/-) transgenic mouse study, there was an increased incidence of subcutaneous sarcomas in females dosed at 200 and 400 mg/kg/day, or 390 and 630 times the human exposure based on AUC comparisons. The incidence of sarcomas was not increased at lower doses that achieved exposures 180 and 60 times the human exposure. These sarcomas were physically associated with subcutaneously implanted animal identification transponders. There were no other increases in tumor incidence of any type in any dose group. These sarcomas are not considered to be relevant to humans.

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. No mutagenic or clastogenic activities were seen in an in vitro mouse lymphoma assay, an in vivo mouse bone marrow micronucleus test, or an ex vivo assay for unscheduled DNA synthesis in rat liver.

Impairment of Fertility: Male and female rats were dosed prior to and during mating, and 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/m2 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.

Pregnancy: Pregnancy Category C

When pregnant rats were administered frovatriptan during the period of organogenesis at oral doses of 100, 500 and 1000 mg/kg/day (equivalent to 130, 650 and 1300 times the maximum recommended human dose [MRHD] on a mg/m2 basis) there were dose related increases in incidences of both litters and total numbers of fetuses with dilated ureters, unilateral and bilateral pelvic cavitation, hydronephrosis, and hydroureters. A no-effect dose for renal effects was not established. This signifies a syndrome of related effects on a specific organ in the developing embryo in all treated groups, which is consistent with a slight delay in fetal maturation. This delay was also indicated by a treatment related increased incidence of incomplete ossification of the sternebrae, skull and nasal bones in all treated groups. Slightly lower fetal weights and an increased incidence of early embryonic deaths in treated rats were observed; although not statistically significant compared to control, the latter effect occurred in both the embryo-fetal developmental study and in the prenatal-postnatal developmental study. There was no evidence of this latter effect at the lowest dose level studied, 100 mg/kg/day (equivalent to 130 times the MRHD on a mg/m2 basis). When pregnant rabbits were dosed throughout organogenesis at doses up to 80 mg/kg/day (equivalent to 210 times the MRHD on a mg/m2 basis) no effects on fetal development were observed.

There are no adequate and well-controlled studies in pregnant women; therefore, frovatriptan should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Nursing Mothers

It is not known whether frovatriptan is excreted in human milk. Frovatriptan and/or its metabolites are excreted in the milk of lactating rats with the maximum concentration being four-fold higher than that seen in blood. Therefore, caution should be exercised when considering the administration of FROVA to a nursing woman.

Pediatric Use

Safety and effectiveness of FROVA in pediatric patients have not been established; therefore, FROVA is not recommended for use in patients under 18 years of age. Postmarketing experience with other triptans includes a limited number of reports that describe pediatric patients who have experienced clinically serious adverse events that are similar in nature to those reported rarely in adults.

Use in the Elderly

Mean blood concentrations of frovatriptan in elderly subjects were 1.5- to 2-times higher than those seen in younger adults (see CLINICAL PHARMACOLOGY, Special Populations). Because migraine occurs infrequently in the elderly, clinical experience with FROVA is limited in such patients.

Drug Abuse And Dependence ⮝

Although the abuse potential of FROVA has not been specifically assessed in clinical trials, no abuse of, tolerance to, withdrawal from, or drug-seeking behavior was observed in patients who received FROVA. The 5-HT1 agonists, as a class, have not been associated with drug abuse.

Overdosage ⮝

There is no direct experience of any patient taking an overdose of FROVA. The maximum single dose of frovatriptan given to male and female patients with migraine was 40 mg (16 times the clinical dose) and the maximum single dose given to healthy male subjects was 100 mg (40 times the clinical dose) without significant adverse events.

As with other 5-HT1 receptor agonists, there is no specific antidote for frovatriptan. The elimination half-life of frovatriptan is 26 hours, therefore if overdose occurs, the patient should be monitored closely for at least 48 hours and be given any necessary symptomatic treatment.

The effects of hemo- or peritoneal dialysis on blood concentrations of frovatriptan are unknown.

Read this information before you start taking FROVA (FRO-va). Also, read the information each time you renew your prescription, in case anything has changed. This leaflet does not contain all of the information about FROVA. For further information or advice ask your doctor or pharmacist. You and your doctor should discuss FROVA before you start taking the medicine and at regular checkups.

What is FROVA?

FROVA is a prescription medicine used to treat migraine attacks in adults. It is in the class of drugs called selective serotonin receptor agonists.

FROVA should only be taken for a migraine headache. Do not use FROVA to treat headaches that might be caused by other conditions. Tell your doctor about your symptoms. Your doctor will decide if you have migraine headaches and if FROVA is for you.

There is more information about migraine at the end of this leaflet.

Who should not take FROVA?

Do not take FROVA if you:

• have uncontrolled high blood pressure
• have heart disease or a history of heart disease
• have hemiplegic or basilar migraine (if you are not sure about this, ask your doctor)
• have had a stroke
• have circulation (blood flow) problems
• have taken a similar drug (a serotonin receptor agonist) in the last 24 hours. These include sumatriptan (IMITREX ), naratriptan (AMERGE ), zolmitriptan (ZOMIG ), rizatriptan (MAXALT ), eletriptan hydrobromide (RELPAX ),or almotriptan (AXERT )
• have taken ergotamine type medicines in the last 24 hours. These include BELLERGAL , CAFERGOT , ERGOMAR , WIGRAINE , DHE 45 , or SANSERT
• have any allergic reaction to the tablet

What you should tell your doctor before and during treatment with FROVA?

To help your doctor decide if FROVA is right for you, tell your doctor if you:

• are pregnant, or planning to become pregnant
• are breast-feeding or plan to breast-feed
• have any history of chest pain, shortness of breath, or palpitations
• have any risk factors for heart disease, including
  • high blood pressure
  • diabetes
  • high cholesterol
  • overweight
  • smoking
  • a family history of heart disease
  • past menopause
  • male over 40 years old
• are taking any other medicines, including prescription and non-prescription medicines, and herbal supplements
• have any past or present medical problems
• have previous allergies to any medicine

Tell your doctor if you take

• propranolol
• selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs), two types of drugs for depression or other disorders. Common SSRIs are CELEXA (citalopram HBr), LEXAPRO (escitalopram oxalate), PAXIL (paroxetine), PROZAC /SARAFEM (fluoxetine), SYMBYAX (olanzapine/fluoxetine), ZOLOFT (sertraline), and fluvoxamine. Common SNRIs are CYMBALTA (duloxetine) and EFFEXOR (venlafaxine).

These medicines may affect how FROVA works, or FROVA may affect how these medicines work.

How should you take FROVA?

Take one FROVA tablet anytime after the start of your migraine headache. If your headache comes back after your first dose, you may take a second tablet after two (2) hours. Do not take more than three (3) FROVA tablets in a 24-hour period.

If you take too much medicine, contact your doctor, hospital emergency department, or poison control center right away.

What are the common side effects of FROVA?

The most common side effects associated with use of FROVA are:

• dizziness
• fatigue (tiredness)
• headache (other than a migraine headache)
• paresthesia (feeling of tingling)
• dry mouth
• flushing (hot flashes)
• feeling hot or cold
• chest pain
• dyspepsia (indigestion)
• skeletal pain (pain in joints or bones)

Tell your doctor about any symptoms that you develop while taking FROVA. If you feel dizziness or fatigue, take extra care or avoid driving and operating machinery.

In very rare cases, patients taking this class of medicines experience serious heart problems, stroke, or increased blood pressure. If you develop pain, tightness, heaviness, or pressure in your chest, throat, neck, or jaw, contact your doctor right away.

Also contact your doctor right away if you develop a rash or itching after taking FROVA. You may be allergic to this medicine.

What is a migraine and how does it differ from other headaches?

Migraine is an intense, throbbing headache that often affects one side of the head. It often includes nausea, vomiting, and sensitivity to light and sound. The pain and symptoms from a migraine headache may be worse than the pain and symptoms of a common headache. Migraine headaches usually last for hours or longer.

Some people have problems with vision (an aura) before they get a migraine headache. These include flashing lights, wavy lines, and dark spots.

Only your doctor can determine that your headache is a migraine headache, so it is important that you discuss all of your symptoms with your doctor.

• Wolff-Parkinson-White Syndrome or arrhythmias associated with other cardiac accessory conduction pathway disorders [see Warnings and Precautions (5.2)].

• History of stroke, transient ischemic attack (TIA), or history of hemiplegic or basilar migraine because these patients are at a higher risk of stroke [see Warnings and Precautions (5.4)].

• Peripheral vascular disease [see Warnings and Precautions (5.5)].

• Ischemic bowel disease [see Warnings and Precautions (5.5)].

• Uncontrolled hypertension [see Warnings and Precautions (5.8)].

• Recent use (i.e., within 24 hours) of another 5-HT1 agonist, an ergotamine containing or ergot-type medication such as dihydroergotamine (DHE) or methysergide [see Drug Interactions (7.1, 7.2)].

• Hypersensitivity to frovatriptan succinate (angioedema and anaphylaxis seen) [see Warnings and Precautions (5.9)].

5 Warnings And Precautions ⮝

5.1 Myocardial Ischemia, Myocardial Infarction, and Prinzmetal s Angina

FROVA is contraindicated in patients with ischemic or vasospastic CAD. There have been rare reports of serious cardiac adverse reactions, including acute myocardial infarction, occurring within a few hours following administration of FROVA. Some of these reactions occurred in patients without known CAD. FROVA may cause coronary artery vasospasm (Prinzmetal s angina), even in patients without a history of CAD.

Perform a cardiovascular evaluation in triptan-na ve patients who have multiple cardiovascular risk factors (e.g., increased age, diabetes, hypertension, smoking, obesity, strong family history of CAD) prior to receiving FROVA. Do not administer FROVA if there is evidence of CAD or coronary artery vasospasm [see Contraindications (4)]. For patients with multiple cardiovascular risk factors who have a negative cardiovascular evaluation, consider administrating the first FROVA dose in a medically-supervised setting and performing an electrocardiogram (ECG) immediately following FROVA administration. For such patients, consider periodic cardiovascular evaluation in intermittent long-term users of FROVA.

5.2 Arrhythmias

Life-threatening disturbances of cardiac rhythm including ventricular tachycardia and ventricular fibrillation leading to death have been reported within a few hours following the administration of 5-HT1 agonists. Discontinue FROVA if these disturbances occur. FROVA is contraindicated in patients with Wolff-Parkinson-White syndrome or arrhythmias associated with other cardiac accessory conduction pathway disorders [see Contraindications (4)].

5.3 Chest, Throat, Neck, and Jaw Pain/Tightness/Pressure

Sensations of pain, tightness, pressure, and heaviness have been reported in the chest, throat, neck, and jaw after treatment with FROVA and are usually non-cardiac in origin. However, perform a cardiac evaluation if these patients are at high cardiac risk. The use of FROVA is contraindicated in patients with CAD and those with Prinzmetal s angina [see Contraindications (4)].

5.4 Cerebrovascular Events

Cerebral hemorrhage, subarachnoid hemorrhage, stroke, and other cerebrovascular events have been reported in patients treated with 5-HT1 agonists, and some have resulted in fatalities. In a number of cases, it appears possible that the cerebrovascular events were primary, the agonist having been administered in the incorrect belief that the symptoms experienced were a consequence of migraine, when they were not.

Before treating headaches in patients not previously diagnosed as migraineurs, and in migraineurs who present with symptoms atypical of migraine, other potentially serious neurological conditions need to be excluded. FROVA is contraindicated in patients with a history of stroke or TIA [see Contraindications (4)].

5.5 Other Vasospasm Reactions

FROVA may cause non-coronary vasospastic reactions, such as peripheral vascular ischemia, gastrointestinal vascular ischemia and infarction (presenting with abdominal pain and bloody diarrhea), splenic infarction, and Raynaud s syndrome. In patients who experience symptoms or signs suggestive of a vasospastic reaction following the use of any 5-HT1 agonist, rule out a vasospastic reaction before using FROVA [see Contraindications (4)].

Reports of transient and permanent blindness and significant partial vision loss have been reported with the use of 5-HT1 agonists. Since visual disorders may be part of a migraine attack, a causal relationship between these events and the use of 5-HT1 agonists have not been clearly established.

5.6 Medication Overuse Headache

Overuse of acute migraine drugs (e.g., ergotamine, triptans, opioids, or combination of these drugs for 10 or more days per month) may lead to exacerbation of headache (medication overuse headache). Medication overuse headache may present as migraine-like daily headaches or as a marked increase in frequency of migraine attacks. Detoxification of patients, including withdrawal of the overused drugs, and treatment of withdrawal symptoms (which often includes a transient worsening of headache) may be necessary.

5.7 Serotonin Syndrome

Serotonin syndrome may occur with FROVA, particularly during co-administration with selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), and monoamine oxidase (MAO) inhibitors [see Drug Interactions (7.3)]. Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, coma), autonomic instability (e.g., tachycardia, labile blood pressure, hyperthermia), neuromuscular aberrations (e.g., hyperreflexia, incoordination), and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). The onset of symptoms usually occurs within minutes to hours of receiving a new or a greater dose of a serotonergic medication. Discontinue FROVA if serotonin syndrome is suspected.

5.8 Increase in Blood Pressure

Significant elevation in blood pressure, including hypertensive crisis with acute impairment of organ systems, has been reported on rare occasions in patients treated with 5-HT1 agonists, including patients without a history of hypertension. Monitor blood pressure in patients treated with FROVA. FROVA is contraindicated in patients with uncontrolled hypertension [see Contraindications (4)].

5.9 Hypersensitivity Reactions

There have been reports of reactions, including anaphylaxis and angioedema, in patients receiving FROVA. Such reactions can be life threatening or fatal. In general, anaphylactic reactions to drugs are more likely to occur in individuals with a history of sensitivity to multiple allergens. FROVA is contraindicated in patients with a history of hypersensitivity reaction to FROVA [see Contraindications (4)].

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)]

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.

FROVA was evaluated in four randomized, double-blind, placebo-controlled, short-term trials. These trials involved 2392 patients (1554 on FROVA 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 FROVA 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 FROVA 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 FROVA 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	FROVA 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 FROVA

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 FROVA. 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.

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 FROVA within 24 hours of each other is contraindicated [see Contraindications (4)].

7.2 5-HT1B/1D Agonists

Because their vasospastic effects may be additive, co-administration of FROVA and other 5-HT1 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)].

8 Use In Specific Populations ⮝

8.1 Pregnancy

Risk Summary

There are no adequate data on the developmental risk associated with the use of FROVA 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/m2) 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/m2 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/m2 basis.

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 FROVA and any potential adverse effects on the breastfed infant from frovatriptan or from the underlying maternal condition.

8.4 Pediatric use

The safety and effectiveness in pediatric patients have not been established. Therefore, FROVA is 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.

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.

8.6 Patients with Hepatic Impairment

No dosage adjustment is necessary when FROVA is given to patients with mild to moderate hepatic impairment.

There is no clinical or pharmacokinetic experience with FROVA 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 FROVA should therefore be used with caution in that population.

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.

11 Description ⮝

FROVA (frovatriptan succinate) tablets contain frovatriptan succinate, a selective 5-hydroxy-tryptamine1 (5-HT1B/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 C14H17N3O.C4H6O4.H2O, representing a molecular weight of 379.4. Frovatriptan succinate is a white to off-white powder that is soluble in water.

Each FROVA 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.

12 Clinical Pharmacology ⮝

12.1 Mechanism of Action

Frovatriptan binds with high affinity to 5-HT1B/1D receptors. The therapeutic activity of FROVA is thought to be due to the agonist effects at the 5-HT1B/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 (Cmax) 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 tmax 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-HT1B/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 FROVA 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 tmax or t1/2 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.

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 Cmax and AUC of frovatriptan are 30% higher in those subjects taking oral contraceptives compared to those not taking oral contraceptives.

Ergotamine

The AUC and Cmax 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 Cmax of frovatriptan was increased 23% in males and 16% in females in the presence of propranolol. The tmax 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.

13 Nonclinical Toxicology ⮝

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/m2 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.

14 Clinical Studies ⮝

The efficacy of FROVA 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 FROVA was provided after the initial treatment, to treat recurrence of the headache within 24 hours. Other medication, excluding other 5-HT1 agonists and ergotamine containing compounds, was permitted from 2 hours after the first dose of FROVA. 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 FROVA 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.

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 FROVA 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 FROVA 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.

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.
