Indications and usage

1 INDICATIONS AND USAGE RizaFilm™ is indicated for the acute treatment of migraine with or without aura in adults and in pediatric patients 6 to 17 years of age. Limitations of Use RizaFilm should only be used where a clear diagnosis of migraine has been established. If a patient has no response for the first migraine attack treated with RizaFilm, the diagnosis of migraine should be reconsidered before RizaFilm is administered to treat any subsequent attacks. RizaFilm is not indicated for the preventive treatment of migraine. Safety and effectiveness of RizaFilm have not been established for cluster headache. RizaFilm is a serotonin (5-HT) 1B/1D receptor agonist (triptan) indicated for the acute treatment of migraine with or without aura in adults and in pediatric patients 6 to 17 years of age (1) Limitations of Use : Use only after a clear diagnosis of migraine has been established (1) Not indicated for the preventive treatment of migraine (1) Not indicated for the treatment of cluster headache (1)

Dosage and administration

2 DOSAGE AND ADMINISTRATION RizaFilm is administered on the tongue (2.1) Adults: 10 mg single dose; separate repeat doses by at least two hours; maximum cumulative dosage in a 24-hour period is 30 mg (2.1) Pediatric patients 6 to 17 years of age: 5 mg single dose in patients less than 40 kg (88 lb); 10 mg single dose in patients 40 kg (88 lb) or more. (2.2) 2.1 Dosing Information in Adults The recommended dose of RizaFilm in adults is 10 mg administered on the tongue. The maximum cumulative dose that may be given in 24 hours is 30 mg, with doses separated by at least 2 hours. The safety of treating, on average, more than four headaches in a 30-day period has not been established. 2.2 Dosing Information in Pediatric Patients (6 to 17 Years of Age) Dosing in pediatric patients is based on the patient's body weight. The recommended dose of RizaFilm is 5 mg in patients weighing less than 40 kg (88 lb), and 10 mg in patients weighing 40 kg (88 lb) or more administered on the tongue. The efficacy and safety of treatment with more than one dose of RizaFilm within 24 hours in pediatric patients 6 to 17 years of age have not been established. 2.3 Administration of RizaFilm Oral Films For RizaFilm oral films, administration with liquid is not necessary. Oral films are packaged individually in child-resistant aluminum pouches with a tear notch. To open the pouch, fold on the dotted line and tear open at the notch. Place the oral film on the tongue, where it will disintegrate within approximately two minutes and can be swallowed with saliva.

Warnings

5 WARNINGS AND PRECAUTIONS Myocardial ischemia, myocardial infarction, and Prinzmetal's angina: Perform cardiac evaluation in patients with multiple cardiovascular risk factors (5.1) Arrhythmias: Discontinue dosing if occurs (5.2) Chest/throat/neck/jaw pain, tightness, pressure, or heaviness; Generally not associated with myocardial ischemia; Evaluate patients at high risk (5.3) Cerebral hemorrhage, subarachnoid hemorrhage, and stroke: Discontinue dosing if occurs (5.4) Gastrointestinal ischemic events, peripheral vasospastic reactions: Discontinue dosing if occurs (5.5) Hypersensitivity Reactions: angioedema and anaphylaxis have occurred (5.6) Medication overuse headache: Detoxification may be necessary (5.7) Serotonin syndrome: Discontinue dosing if occurs (5.8) 5.1 Myocardial Ischemia, Myocardial Infarction, and Prinzmetal's Angina RizaFilm should not be given to patients with ischemic or vasospastic coronary artery disease. There have been rare reports of serious cardiac adverse reactions, including acute myocardial infarction, occurring within a few hours following administration of rizatriptan benzoate. Some of these reactions occurred in patients without known coronary artery disease (CAD). 5-HT1 agonists, including RizaFilm may cause coronary artery vasospasm (Prinzmetal's Angina), even in patients without a history of CAD. Perform a cardiovascular evaluation in triptan-naïve patients who have multiple cardiovascular risk factors (e.g., increased age, diabetes, hypertension, smoking, obesity, strong family history of CAD) before receiving RizaFilm. If there is evidence of CAD or coronary artery vasospasm, RizaFilm is contraindicated. For patients with multiple cardiovascular risk factors who have a negative cardiovascular evaluation, consider administering the first RizaFilm dose in a medically supervised setting and performing an electrocardiogram (ECG) immediately following RizaFilm administration. For such patients, consider periodic cardiovascular evaluation in intermittent long-term users of RizaFilm. 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 RizaFilm if these disturbances occur. RizaFilm is contraindicated in patients with Wolff-Parkinson-White syndrome or arrhythmias associated with other cardiac accessory conduction pathway disorder. 5.3 Chest, Throat, Neck, and/or Jaw Pain/Tightness/Pressure Sensations of tightness, pain, pressure, and heaviness in the precordium, throat, neck, and jaw commonly occur after treatment with rizatriptan, the active moiety in RizaFilm, and are usually noncardiac in origin. However, perform a cardiac evaluation if these patients are at a high cardiac risk. The use of RizaFilm is contraindicated in patients with CAD and those with Prinzmetal's variant angina. 5.4 Cerebrovascular Events Cerebral hemorrhage, subarachnoid hemorrhage, and stroke have occurred 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 5-HT1 agonist having been administered in the incorrect belief that the symptoms experienced were a consequence of migraine, when they were not. Also, patients with migraine may be at increased risk of certain cerebrovascular events (e.g., stroke, hemorrhage, transient ischemic attack). Discontinue RizaFilm if a cerebrovascular event occurs. Before treating headaches in patients not previously diagnosed with migraine or in patients who present with atypical symptoms, exclude other potentially serious neurological conditions. RizaFilm is contraindicated in patients with a history of stroke or transient ischemic attack. 5.5 Other Vasospasm Reactions 5-HT 1 agonists, including RizaFilm, may cause non-coronary vasospastic reactions, such as peripheral vascular ischemia, …

Drug interactions

7 DRUG INTERACTIONS 7.1 Propranolol Because propranolol increases the exposure of rizatriptan and dosage adjustment is not possible with RizaFilm, concomitant use of RizaFilm with propranolol is contraindicated [see Contraindications (4) and Clinical Pharmacology (12.3) ] . 7.2 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 RizaFilm within 24 hours is contraindicated [ see Contraindications (4) ]. 7.3 Other 5-HT 1 Agonists Because their vasospastic effects may be additive, co-administration of RizaFilm and other 5-HT 1 agonists within 24 hours of each other is contraindicated [ see Contraindications (4) ]. 7.4 SSRIs/SNRIs and Serotonin Syndrome Cases of serotonin syndrome have been reported during co-administration of triptans and selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) [see Warnings and Precautions (5.7) ] . 7.5 Monoamine Oxidase Inhibitors Because of an increase in the systemic exposure of rizatriptan and its metabolite, RizaFilm is contraindicated in patients taking MAO-A inhibitors and non-selective MAO inhibitors [see Contraindications (4) and Clinical Pharmacology (12.3) ] . Drug Interactions Monoamine Oxidase Inhibitors: In a drug interaction study, when rizatriptan benzoate 10 mg tablets were administered to subjects (n=12) receiving concomitant therapy with the selective, reversible MAO-A inhibitor, moclobemide 150 mg three times a day, there were mean increases in rizatriptan AUC and C max of 119% and 41%, respectively; and the AUC of the active N-monodesmethyl metabolite of rizatriptan was increased more than 400%. The interaction would be expected to be greater with irreversible MAO inhibitors [see Contraindications (4) and Drug Interactions (7.5) ]. No pharmacokinetic interaction is anticipated in patients receiving selective MAO-B inhibitors. Propranolol: In a study of concurrent administration of propranolol 240 mg/day and a single dose of rizatriptan 10 mg in healthy adult subjects (n=11), mean plasma AUC for rizatriptan was increased by 70%, and a four-fold increase was observed in one subject [see Contraindications (4) and Drug Interactions (7.1) ]. The AUC of the active N-monodesmethyl metabolite of rizatriptan was not affected by propranolol. Nadolol/Metoprolol: In a drug interactions study, effects of multiple doses of nadolol 80 mg or metoprolol 100 mg every 12 hours on the pharmacokinetics of a single dose of 10 mg rizatriptan were evaluated in healthy subjects (n=12). No pharmacokinetic interactions were observed. Paroxetine: In a study of the interaction between the selective serotonin reuptake inhibitor (SSRI) paroxetine 20 mg/day for two weeks and a single dose of rizatriptan benzoate tablet 10 mg in healthy subjects (n=12), neither the plasma concentrations of rizatriptan nor its safety profile were affected by paroxetine [see Warnings and Precautions (5.7) , Drug Interactions (7.4) , and Patient Counseling Information (17) ]. Oral Contraceptives: In a study of concurrent administration of an oral contraceptive during 6 days of administration of rizatriptan (10-30 mg/day) in healthy female volunteers (n=18), rizatriptan did not affect plasma concentrations of ethinyl estradiol or norethindrone.

Pregnancy

8.1 Pregnancy Risk Summary Available human data on the use of rizatriptan in pregnant women are not sufficient to draw conclusions about drug-associated risk for major birth defects and miscarriage. In animal studies, developmental toxicity was observed following oral administration of rizatriptan during pregnancy (decreased fetal body weight in rats) or throughout pregnancy and lactation (increased mortality, decreased body weight, and neurobehavioral impairment in rat offspring) at maternal plasma exposures greater than that expected at therapeutic doses in humans [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% to 4% and 15% to 20%, respectively. The reported rate of major birth defects among deliveries to women with migraine range from 2.2% to 2.9% and the reported rate of miscarriage was 17%, which are similar to rates reported in women without migraine. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk In women with migraine, there is an increased risk of adverse perinatal outcomes in the mother, including pre-eclampsia and gestational hypertension. Data Human Data The Pregnancy Registry for rizatriptan did not identify any pattern of congenital anomalies or other adverse birth outcomes over the period of 1998 to 2018. However, the lack of identification of any pattern should be viewed with caution, as the number of prospective reports with outcome information was low and did not provide sufficient power to detect an increased risk of individual birth defects associated with the use of rizatriptan. Additionally, there was significant loss to follow-up in the prospective pregnancy reports, further complicating this assessment of an association between rizatriptan and any pattern of congenital anomalies or other adverse birth outcomes. In a study using data from the Swedish Medical Birth Register, live births to women who reported using triptans or ergots during pregnancy were compared with those of women who did not. Of the 157 births with first-trimester exposure to rizatriptan, 7 infants were born with malformations (relative risk 1.01 [95% CI: 0.40 to 2.08]). A study using linked data from the Medical Birth Registry of Norway to the Norwegian Prescription Database compared pregnancy outcomes in women who redeemed prescriptions for triptans during pregnancy, as well as a migraine disease comparison group who redeemed prescriptions for triptans before pregnancy only, compared with a population control group. Of the 310 women who redeemed prescriptions for rizatriptan during the first trimester, 10 had infants with major congenital malformations (OR 1.03 [95% CI: 0.55 to 1.93]), while for the 271 women who redeemed prescriptions for rizatriptan before but not during pregnancy, 12 had infants with major congenital malformations (OR 1.48 [95% CI: 0.83 to 2.64]), each compared with the population comparison group. Animal Data When rizatriptan (0, 2, 10, or 100 mg/kg/day) was administered orally to pregnant rats throughout organogenesis, a decrease in fetal body weight was observed at the highest doses tested. At the mid-dose (10 mg/kg/day), which was a no-effect dose for adverse effects on embryofetal development, plasma exposure (AUC) was approximately 15 times that in humans at the maximum recommended human dose (MRHD) of 30 mg/day. When rizatriptan (0, 5, 10, or 50 mg/kg/day) was administered orally to pregnant rabbits throughout organogenesis, no adverse fetal effects were observed. Plasma exposure (AUC) at the highest dose tested was 115 times that in humans at the MRHD. Placental transfer of the drug to the fetus was demonstrated in both species. Oral administration of rizatriptan (0, 2, 10, or 100 mg/kg/day) to female rats before and during mating and continuing throughout gestation and lactation resulted in reduced body weight in offspring from birth and throughout lactation at …

Nursing mothers

8.2 Lactation Risk Summary There are no data on the presence of rizatriptan or any active metabolites in human milk or on the effects of rizatriptan on the breastfed infant, or milk production. Rizatriptan was excreted in rat milk, with levels in milk approximately 6 times those in maternal plasma. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for RizaFilm and any potential adverse effects on the breastfed infant from RizaFilm or the underlying maternal condition. Data Following oral administration of rizatriptan to lactating rats at a dose of 100 mg/kg/day, the drug concentrations of rizatriptan in milk samples exceeded maternal plasma drug concentrations by approximately 6-fold.

Adverse reactions (label)

6 ADVERSE REACTIONS The following serious adverse reactions are discussed in more detail 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 and or 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) ]. Hypersensitivity Reactions [see Warnings and Precautions (5.6) ] Medication Overuse Headache [see Warnings and Precautions (5.7) ]. Serotonin Syndrome [see Warnings and Precautions (5.8) ]. Increase in Blood Pressure [see Warnings and Precautions (5.9) ]. The most common adverse reactions in adults were (incidence ≥5% and greater than placebo): asthenia/fatigue, somnolence, pain/pressure sensation, dizziness, and nausea ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Gensco Pharma at 1-866-608-6284 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. The studies described below were conducted with rizatriptan benzoate tablets; adverse reactions with RizaFilm are expected to be similar to rizatriptan benzoate tablets. Adults Incidence in Controlled Clinical Trials Adverse reactions to rizatriptan benzoate were assessed in controlled clinical trials that included over 3700 adult patients who received single or multiple doses of rizatriptan benzoate tablets. The most common adverse reactions during treatment with rizatriptan benzoate (≥5% in either treatment group and greater than placebo) were asthenia/fatigue, somnolence, pain/pressure sensation, dizziness, and nausea. Table 1 lists the adverse reactions (incidence ≥2% and greater than placebo) after a single dose of rizatriptan benzoate in adults. Table 1: Incidence (≥2% and Greater than Placebo) of Adverse Reactions After a Single Dose of Rizatriptan Benzoate Tablets or Placebo in Adults % of Patients Adverse Reactions Rizatriptan Benzoate 5 mg (N=977) % Rizatriptan Benzoate 10 mg (N=1167) % Placebo (N=627) % Atypical Sensations 4 5 4 Paresthesia 3 4 <2 Pain and other Pressure Sensations 6 9 3 Chest Pain: tightness/pressure and/or heaviness <2 3 1 Pain, location unspecified 3 3 <2 Neck/throat/jaw: pain/tightness/pressure <2 2 1 Regional Pain: tightness/pressure and/or heaviness <1 2 0 Digestive 9 13 8 Nausea 4 6 4 Dry Mouth 3 3 1 Neurological 14 20 11 Dizziness 4 9 5 Somnolence 4 8 4 Headache <2 2 <1 Other Asthenia/fatigue 4 7 2 The frequencies of adverse reactions in clinical trials did not increase when up to three doses were taken within 24 hours. Adverse reaction frequencies were also unchanged by concomitant use of drugs commonly taken for migraine prophylaxis, oral contraceptives, or analgesics. The incidences of adverse reactions were not affected by age or gender. There were insufficient data to assess the impact of race on the incidence of adverse reactions. Other Events Observed in Association with the Administration of Rizatriptan Benzoate in Adults In the following section, the frequencies of less commonly reported adverse events are presented that were not reported in other sections of the labeling. Because the reports include events observed in open studies, the role of rizatriptan benzoate in their causation cannot be reliably determined. Furthermore, variability associated with adverse event reporting, the terminology used to describe adverse events, limit the value of the quantitative frequency estimates provided. Event frequencies are calculated as the number of patients who used rizatriptan benzoate and reported an event divided by the total number of patients ex…
