6 ADVERSE REACTIONS The following adverse reactions are described in more detail in the Warnings and Precautions section of the label: Hypertension [see Warnings and Precautions ( 5.1 )] Serotonin Syndrome [see Warnings and Precautions ( 5.2 )] Falling Asleep During Activities of Daily Living and Somnolence [see Warnings and Precautions ( 5.3 )] Hypotension / Orthostatic Hypotension [see Warnings and Precautions ( 5.6 )] Dyskinesia [see Warnings and Precautions ( 5.7 )] Hallucinations / Psychotic-Like Behavior [see Warnings and Precautions ( 5.8 )] Impulse Control /Compulsive Behaviors [see Warnings and Precautions ( 5.9 )] Withdrawal-Emergent Hyperpyrexia and Confusion [see Warnings and Precautions ( 5.10 )] Most common adverse reactions (incidence 3% or greater than placebo): Rasagiline monotherapy: flu syndrome, arthralgia, depression, dyspepsia ( 6.1 ) Rasagiline used as adjunct without levodopa: peripheral edema, fall, arthralgia, cough, and insomnia (6.1) Rasagiline used as adjunct to levodopa: dyskinesia, accidental injury, weight loss, postural hypotension, vomiting, anorexia, arthralgia, abdominal pain, nausea, constipation, dry mouth, rash, abnormal dreams, fall, and tenosynovitis (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Alvogen, Inc. at 1-866-770-3024 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 the incidence of adverse reactions in the clinical trials of another drug and may not reflect the rates of adverse reactions observed in practice. During the clinical development of rasagiline, Parkinson’s disease patients received rasagiline as initial monotherapy (Study 1) and as adjunct therapy (Study 2, Study 3, Study 4). As the populations in these studies differ, not only in the adjunct use of dopamine agonists or levodopa during rasagiline treatment, but also in the severity and duration of their disease, the adverse reactions are presented separately for each study. Monotherapy Use of Rasagiline In Study 1, approximately 5% of the 149 patients treated with rasagiline discontinued treatment due to adverse reactions compared to 2% of the 151 patients who received placebo. The only adverse reaction that led to the discontinuation of more than one patient was hallucinations. The most commonly observed adverse reactions in Study 1 (incidence in rasagiline-treated patients 3% or greater than the incidence in placebo-treated patients) included flu syndrome, arthralgia, depression, and dyspepsia. Table 1 lists adverse reactions that occurred in 2% or greater of patients receiving rasagiline as monotherapy and were numerically more frequent than in the placebo group in Study 1.

Adjunct Use of Rasagiline Rasagiline was studied as an adjunct therapy without levodopa (Study 2), or as an adjunct therapy to levodopa, with some patients also taking dopamine agonists, COMT inhibitors, anticholinergics, or amantadine (Study 3 and Study 4). In Study 2, approximately 8% of the 162 patients treated with rasagiline discontinued treatment due to adverse reactions compared to 4% of the 164 patients who received placebo. Adverse reactions that led to the discontinuation of more than one patient were nausea and dizziness. The most commonly observed adverse reactions in Study 2 (incidence in rasagiline-treated patients 3% or greater than incidence in placebo-treated patients) included peripheral edema, fall, arthralgia, cough, and insomnia. Table 2 lists adverse reactions that occurred in 2% or greater in patients receiving rasagiline as adjunct therapy without levodopa and numerically more frequent than in the placebo group in Study 2.

In Study 3, adverse event reporting was considered more reliable than Study 4; therefore, only the adverse event data from Study 3 are presented below. In Study 3, approximately 9% of the 164 patients treated with rasagiline 0.5 mg/day and 7% of the 149 patients treated with rasagiline 1 mg/day discontinued treatment due to adverse reactions, compared to 6% of the 159 patients who received placebo. The adverse reactions that led to discontinuation of more than one rasagiline-treated patient were diarrhea, weight loss, hallucination, and rash. The most commonly observed adverse reactions in Study 3 (incidence in rasagiline-treated patients 3% or greater than the incidence in placebo-treated patients) included dyskinesia, accidental injury, weight loss, postural hypotension, vomiting, anorexia, arthralgia, abdominal pain, nausea, constipation, dry mouth, rash, abnormal dreams, fall, and tenosynovitis. Table 3 lists adverse reactions that occurred in 2% or greater of patients treated with rasagiline 1 mg/day and that were numerically more frequent than the placebo group in Study 3.

There were no significant differences in the safety profile based on age or gender. During all Parkinson's disease phase 2/3 clinical trials, the long-term safety profile was similar to that observed with shorter duration exposure. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of rasagiline. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Skin and Subcutaneous Tissue Disorders: Melanoma

Dosage And Administration
2 DOSAGE AND ADMINISTRATION Monotherapy: Rasagiline tablets 1 mg once daily ( 2.1 ) As adjunct without levodopa: Rasagiline tablets 1 mg once daily (2.1) As adjunct to levodopa: Rasagiline tablets 0.5 mg once daily. Increase dose to 1 mg daily as needed for sufficient clinical response (2.1) Patients taking ciprofloxacin or other CYP1A2 inhibitors: Rasagiline tablets 0.5 mg once daily ( 2.2 , 5.4 ) Patients with mild hepatic impairment: Rasagiline tablets 0.5 mg once daily. Rasagiline tablets should not be used in patients with moderate or severe hepatic impairment ( 2.3 , 5.5 ) 2.1 General Dosing Recommendations When rasagiline tablets are prescribed as monotherapy or as adjunct therapy in patients not taking levodopa, patients may start rasagiline tablets at the recommended dose of 1 mg administered orally once daily. In patients taking levodopa, with or without other PD drugs (e.g., dopamine agonist, amantadine, anticholinergics), the recommended initial dose of rasagiline tablets is 0.5 mg once daily. If the patient tolerates the daily 0.5 mg dose, but a sufficient clinical response is not achieved, the dose may be increased to 1 mg once daily. When rasagiline tablets are used in combination with levodopa, a reduction of the levodopa dose may be considered, based upon individual response. The recommended doses of rasagiline tablets should not be exceeded because of risk of hypertension [see Warnings and Precautions ( 5.1 )] . 2.2 Patients Taking Ciprofloxacin or Other CYP1A2 Inhibitors Patients taking concomitant ciprofloxacin or other CYP1A2 inhibitors should not exceed a dose of rasagiline tablets 0.5 mg once daily [see Warnings and Precautions ( 5.4 ), Drug Interactions ( 7.6 ), and Clinical Pharmacology ( 12.3 )] . 2.3 Patients with Hepatic Impairment Patients with mild hepatic impairment should not exceed a dose of rasagiline tablets 0.5 mg once daily. Rasagiline tablets should not be used in patients with moderate or severe hepatic impairment [see Warnings and Precautions ( 5.5 ), Use in Specific Populations ( 8.6 ), and Clinical Pharmacology ( 12.3 )] .

Overdosage
10 OVERDOSAGE In a dose escalation study in patients on chronic levodopa therapy treated with 10 mg of rasagiline there were three reports of cardiovascular side effects (including hypertension and postural hypotension) which resolved following treatment discontinuation. Although no cases of overdose have been observed with rasagiline during the clinical development program, the following description of presenting symptoms and clinical course is based upon overdose descriptions of nonselective MAO inhibitors. The signs and symptoms of nonselective MAOI overdose may not appear immediately. Delays of up to 12 hours after ingestion of drug and the appearance of signs may occur. The peak intensity of the syndrome may not be reached until for a day following the overdose. Death has been reported following overdose; therefore, immediate hospitalization, with continuous patient observation and monitoring for at least two days following the ingestion of such drugs in overdose, is strongly recommended. The severity of the clinical signs and symptoms of MAOI overdose varies and may be related to the amount of drug consumed. The central nervous and cardiovascular systems are prominently involved. Signs and symptoms of MAOI overdose may include: drowsiness, dizziness, faintness, irritability, hyperactivity, agitation, severe headache, hallucinations, trismus, opisthotonos, convulsions, and coma; rapid and irregular pulse, hypertension, hypotension and vascular collapse; precordial pain, respiratory depression and failure, hyperpyrexia, diaphoresis, and cool, clammy skin. There is no specific antidote for rasagiline overdose. The following suggestions are offered based upon the assumption that rasagiline overdose may be modeled after nonselective MAO inhibitor poisoning. Treatment of overdose with nonselective MAO inhibitors is symptomatic and supportive. Respiration should be supported by appropriate measures, including management of the airway, use of supplemental oxygen, and mechanical ventilatory assistance, as required. Body temperature should be monitored closely. Intensive management of hyperpyrexia may be required. Maintenance of fluid and electrolyte balance is essential. For this reason, in cases of overdose with rasagiline, dietary tyramine restriction should be observed for several weeks to reduce the risk of hypertensive tyramine reaction. A poison control center should be called for the most current treatment guidelines. A postmarketing report described a single patient who developed a nonfatal serotonin syndrome after ingesting 100 mg of rasagiline in a suicide attempt. Another patient who was treated in error with 4 mg rasagiline daily and tramadol also developed a serotonin syndrome. One patient who was treated in error with 3 mg rasagiline daily experienced alternating episodes of vascular fluctuations consisting of hypertension and orthostatic hypotension.

Drug Interactions
7 DRUG INTERACTIONS Meperidine: Risk of serotonin syndrome ( 4 , 7.1 ) Dextromethorphan: Risk of psychosis or bizarre behavior (4, 7.2 ) MAO inhibitors: Risk of non-selective MAO inhibition and hypertensive crisis (4, 7.3 ) 7.1 Meperidine Serious, sometimes fatal reactions have been precipitated with concomitant use of meperidine (e.g., Demerol and other tradenames) and MAO inhibitors including selective MAO-B inhibitors [see Contraindications ( 4 )] . 7.2 Dextromethorphan The concomitant use of rasagiline and dextromethorphan was not allowed in clinical studies. The combination of MAO inhibitors and dextromethorphan has been reported to cause brief episodes of psychosis or bizarre behavior. Therefore, in view of rasagiline’s MAO inhibitory activity, dextromethorphan is contraindicated for use with rasagiline [see Contraindications ( 4 )] . 7.3 MAO Inhibitors Rasagiline is contraindicated for use with other MAO inhibitors because of the increased risk of nonselective MAO inhibition that may lead to a hypertensive crisis [see Contraindications ( 4 )] . 7.4 Sympathomimetic Medications The concomitant use of rasagiline and sympathomimetic medications was not allowed in clinical studies. Severe hypertensive reactions have followed the administration of sympathomimetics and nonselective MAO inhibitors. Hypertensive crisis has been reported in patients taking the recommended dose of rasagiline and sympathomimetic medications. Severe hypertension has been reported in patients taking the recommended dose of rasagiline and ophthalmic drops containing sympathomimetic medications. Because rasagiline is a selective MAOI, hypertensive reactions are not ordinarily expected with the concomitant use of sympathomimetic medications. Nevertheless, caution should be exercised when concomitantly using recommended doses of rasagiline with any sympathomimetic medications including nasal, oral, and ophthalmic decongestants and cold remedies. 7.5 Antidepressants Concomitant use of rasagiline with one of many classes of antidepressants (e.g., SSRIs, SNRIs, triazolopyridine, tricyclic, or tetracyclic antidepressants) is not recommended [see Warnings and Precautions ( 5.2 ) and Clinical Pharmacology ( 12.3 )] . Concomitant use of rasagiline and MAO inhibitors is contraindicated [see Contraindications ( 4 )] . 7.6 Ciprofloxacin or Other CYP1A2 Inhibitors Rasagiline plasma concentrations may increase up to 2 fold in patients using concomitant ciprofloxacin and other CYP1A2 inhibitors. This could result in increased adverse events. Patients taking concomitant ciprofloxacin or other CYP1A2 inhibitors should not exceed a dose of rasagiline 0.5 mg once daily [see Warnings and Precautions ( 5.4 ) and Clinical Pharmacology ( 12.3 )] . 7.7 Tyramine/Rasagiline Interaction MAO in the gastrointestinal tract and liver (primarily type A) provides protection from exogenous amines (e.g., tyramine) that have the capacity, if absorbed intact, to cause a tyramine reaction with hypertension including clinical syndromes referred to as hypertensive urgency, crisis, or emergency. Foods and medications containing large amounts of exogenous amines (e.g., from fermented cheese, herring, over-the-counter cough/cold medications) may cause release of norepinephrine resulting in a rise in systemic blood pressure. Results of a special tyramine challenge study indicate that rasagiline is selective for MAO-B at recommended doses and can be used without dietary tyramine restriction. However, certain foods may contain very high amounts (i.e., 150 mg or greater) of tyramine and could potentially cause a hypertensive reaction in individual patients taking rasagiline due to increased sensitivity to tyramine. Selectivity for inhibiting MAO-B diminishes in a dose-related manner as the dose is progressively increased above the recommended daily doses. There were no cases of hypertensive crisis in the clinical development program associated with 1 mg daily rasagiline treatment, in which most patients did not follow dietary tyramine restriction. There have been postmarketing reports of patients who experienced significantly elevated blood pressure (including rare cases of hypertensive crisis) after ingestion of unknown amounts of tyramine-rich foods while taking recommended doses of rasagiline. Patients should be advised to avoid foods containing a very large amount of tyramine while taking recommended doses of rasagiline [see Warnings and Precautions ( 5.1 )] . 7.8 Dopaminergic Antagonists It is possible that dopamine antagonists, such as antipsychotics or metoclopramide, could diminish the effectiveness of rasagiline.
Clinical Pharmacology
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Rasagiline is a selective, irreversible MAO-B inhibitor indicated for the treatment of idiopathic Parkinson’s disease. The results of a clinical trial designed to examine the effects of rasagiline on blood pressure when it is administered with increasing doses of tyramine indicates the functional selectivity can be incomplete when healthy subjects ingest large amounts of tyramine while receiving recommended doses of rasagiline. The selectivity for inhibiting MAO-B diminishes in a dose-related manner. MAO, a flavin-containing enzyme, is classified into two major molecular species, A and B, and is localized in mitochondrial membranes throughout the body in nerve terminals, brain, liver and intestinal mucosa. MAO regulates the metabolic degradation of catecholamines and serotonin in the CNS and peripheral tissues. MAO-B is the major form in the human brain. In ex vivo animal studies in brain, liver, and intestinal tissues, rasagiline was shown to be a potent, irreversible monoamine oxidase type B (MAO-B) selective inhibitor. Rasagiline at the recommended therapeutic dose was also shown to be a potent and irreversible inhibitor of MAO-B in platelets. The precise mechanisms of action of rasagiline are unknown. One mechanism is believed to be related to its MAO-B inhibitory activity, which causes an increase in extracellular levels of dopamine in the striatum. The elevated dopamine level and subsequent increased dopaminergic activity are likely to mediate rasagiline’s beneficial effects seen in models of dopaminergic motor dysfunction. 12.2 Pharmacodynamics Tyramine Challenge Test Results of a tyramine challenge study indicate that rasagiline at recommended doses is relatively selective for inhibiting MAO-B and can be used without dietary tyramine restriction. However, certain foods (e.g., aged cheeses, such as Stilton cheese) may contain very high amounts of tyramine (i.e., 150 mg or greater) and could potentially cause severe hypertension caused by tyramine interaction in patients taking rasagiline due to mild increased sensitivity to tyramine at recommended doses. Relative selectivity of rasagiline for inhibiting MAO-B diminished in a dose-related manner as the dose progressively increased above the highest recommended daily dose (1 mg) [see Warnings and Precautions ( 5.1 ) and Drug Interactions ( 7.7 )] . Platelet MAO Activity in Clinical Studies Studies in healthy subjects and in Parkinson’s disease patients have shown that rasagiline inhibits platelet MAO-B irreversibly. The inhibition lasts at least 1 week after last dose. Almost 25 to 35% MAO-B inhibition was achieved after a single rasagiline dose of 1 mg/day and more than 55% of MAO-B inhibition was achieved after a single rasagiline dose of 2 mg/day. Over 90% inhibition was achieved 3 days after rasagiline daily dosing at 2 mg/day and this inhibition level was maintained 3 days postdose. Multiple doses of rasagiline of 0.5, 1, and 2 mg per day resulted in complete MAO-B inhibition. 12.3 Pharmacokinetics Rasagiline in the range of 1 to 6 mg demonstrated a more than proportional increase in AUC, while C max was dose proportional. Rasagiline mean steady-state half life is 3 hours but there is no correlation of pharmacokinetics with its pharmacological effect because of its irreversible inhibition of MAO-B. Absorption Rasagiline is rapidly absorbed, reaching peak plasma concentration (C max ) in approximately 1 hour. The absolute bioavailability of rasagiline is about 36%. Food does not affect the T max of rasagiline, although C max and exposure (AUC) are decreased by approximately 60% and 20%, respectively, when the drug is taken with a high fat meal. Because AUC is not significantly affected, rasagiline can be administered with or without food. Distribution The mean volume of distribution at steady-state is 87 L, indicating that the tissue binding of rasagiline is in excess of plasma protein binding. Plasma protein binding ranges from 88 to 94% with mean extent of binding of 61 to 63% to human albumin over the concentration range of 1 to 100 ng/mL. Metabolism and Elimination Rasagiline undergoes almost complete biotransformation in the liver prior to excretion. The metabolism of rasagiline proceeds through two main pathways: N-dealkylation and/or hydroxylation to yield 1-aminoindan (AI), 3-hydroxy-N-propargyl-1-aminoindan (3-OH-PAI) and 3-hydroxy-1-aminoindan (3-OH-AI). In vitro experiments indicate that both routes of rasagiline metabolism are dependent on the cytochrome P450 (CYP) system, with CYP1A2 being the major isoenzyme involved in rasagiline metabolism. Glucuronide conjugation of rasagiline and its metabolites, with subsequent urinary excretion, is the major elimination pathway. After oral administration of 14 C-labeled rasagiline, elimination occurred primarily via urine and secondarily via feces (62% of total dose in urine and 7% of total dose in feces over 7 days), with a total calculated recovery of 84% of the dose over a period of 38 days. Less than 1% of rasagiline was excreted as unchanged drug in urine. Specific Populations Hepatic Impairment Following repeat dose administration (7 days) of rasagiline (1 mg/day) in subjects with mild hepatic impairment (Child-Pugh score 5 to 6), AUC and Cmax were increased by 2 fold and 1.4 fold, respectively, compared to healthy subjects. In subjects with moderate hepatic impairment (Child-Pugh score 7 to 9), AUC and C max were increased by 7 fold and 2 fold, respectively, compared to healthy subjects [see Dosage and Administration (2.3) and Warnings and Precautions (5.5)]. Renal Impairment Following repeat dose administration (8 days) of rasagiline (1 mg/day) in subjects with moderate renal impairment, rasagiline exposure (AUC) was similar to rasagiline exposure in healthy subjects, while the major metabolite 1-AI exposure (AUC) was increased 1.5 fold in subjects with moderate renal impairment, compared to healthy subjects. Because 1-AI is not an MAO inhibitor, no dose adjustment is needed for patients with mild and moderate renal impairment. Data are not available for patients with severe renal impairment. Elderly Since age has little influence on rasagiline pharmacokinetics, it can be administered at the recommended dose in the elderly (≥ 65 years). Pediatric Rasagiline has not been investigated in patients below 18 years of age. Gender The pharmacokinetic profile of rasagiline is similar in men and women. Drug-Drug Interactions Levodopa A study in Parkinson’s disease patients, in which the effect of levodopa/carbidopa (LD/CD) on rasagiline pharmacokinetics at steady state was investigated, showed that the pharmacokinetics of rasagiline were not affected by concomitant administration of LD/CD. Effect of Other Drugs on the Metabolism of Rasagiline In vitro metabolism studies showed that CYP1A2 was the major enzyme responsible for the metabolism of rasagiline. There is the potential for inhibitors of this enzyme to alter rasagiline clearance when coadministered [see Dosage and Administration (2.2) and Warnings and Precautions (5.4)]. Ciprofloxacin: When ciprofloxacin, an inhibitor of CYP1A2, was administered to healthy volunteers (n=12) at 500 mg (BID) with rasagiline at 2 mg/day, the AUC of rasagiline increased by 83% and there was no change in the elimination half life [see Dosage and Administration (2.2) and Warnings and Precautions (5.4)]. Theophylline: Coadministration of rasagiline 1 mg/day and theophylline, a substrate of CYP1A2, up to 500 mg twice daily to healthy subjects (n=24) did not affect the pharmacokinetics of either drug. Antidepressants: Severe CNS toxicity (occasionally fatal) associated with hyperpyrexia as part of a serotonin syndrome, has been reported with combined treatment of an antidepressant (e.g., from one of many classes including tricyclic or tetracyclic antidepressants, SSRIs, SNRIs, triazolopyridine antidepressants) and nonselective MAOI or a selective MAO-B inhibitor [see Warnings and Precautions (5.2)]. Effect of Rasagiline on Other Drugs No additional in vivo trials have investigated the effect of rasagiline on other drugs metabolized by the cytochrome P450 enzyme system. In vitro studies showed that rasagiline at a concentration of 1 mcg/mL (equivalent to a level that is 160 times the average C max ~ 5.9 to 8.5 ng/mL in Parkinson’s disease patients after 1 mg rasagiline multiple dosing) did not inhibit cytochrome P450 isoenzymes, CYP1A2, CYP2A6, CYP2C9, CYP2C19, CYP2D6, CYP2E1, CYP3A4 and CYP4A. These results indicate that rasagiline is unlikely to cause any clinically significant interference with substrates of these enzymes.
Mechanism Of Action
12.1 Mechanism of Action Rasagiline is a selective, irreversible MAO-B inhibitor indicated for the treatment of idiopathic Parkinson’s disease. The results of a clinical trial designed to examine the effects of rasagiline on blood pressure when it is administered with increasing doses of tyramine indicates the functional selectivity can be incomplete when healthy subjects ingest large amounts of tyramine while receiving recommended doses of rasagiline.

The metabolism of rasagiline proceeds through two main pathways: N-dealkylation and/or hydroxylation to yield 1-aminoindan (AI), 3-hydroxy-N-propargyl-1-aminoindan (3-OH-PAI) and 3-hydroxy-1-aminoindan (3-OH-AI). In vitro experiments indicate that both routes of rasagiline metabolism are dependent on the cytochrome P450 (CYP) system, with CYP1A2 being the major isoenzyme involved in rasagiline metabolism. Glucuronide conjugation of rasagiline and its metabolites, with subsequent urinary excretion, is the major elimination pathway. After oral administration of 14 C-labeled rasagiline, elimination occurred primarily via urine and secondarily via feces (62% of total dose in urine and 7% of total dose in feces over 7 days), with a total calculated recovery of 84% of the dose over a period of 38 days. Less than 1% of rasagiline was excreted as unchanged drug in urine. Specific Populations Hepatic Impairment Following repeat dose administration (7 days) of rasagiline (1 mg/day) in subjects with mild hepatic impairment (Child-Pugh score 5 to 6), AUC and Cmax were increased by 2 fold and 1.4 fold, respectively, compared to healthy subjects. In subjects with moderate hepatic impairment (Child-Pugh score 7 to 9), AUC and C max were increased by 7 fold and 2 fold, respectively, compared to healthy subjects [see Dosage and Administration (2.3) and Warnings and Precautions (5.5)]. Renal Impairment Following repeat dose administration (8 days) of rasagiline (1 mg/day) in subjects with moderate renal impairment, rasagiline exposure (AUC) was similar to rasagiline exposure in healthy subjects, while the major metabolite 1-AI exposure (AUC) was increased 1.5 fold in subjects with moderate renal impairment, compared to healthy subjects. Because 1-AI is not an MAO inhibitor, no dose adjustment is needed for patients with mild and moderate renal impairment. Data are not available for patients with severe renal impairment. Elderly Since age has little influence on rasagiline pharmacokinetics, it can be administered at the recommended dose in the elderly (≥ 65 years). Pediatric Rasagiline has not been investigated in patients below 18 years of age. Gender The pharmacokinetic profile of rasagiline is similar in men and women. Drug-Drug Interactions Levodopa A study in Parkinson’s disease patients, in which the effect of levodopa/carbidopa (LD/CD) on rasagiline pharmacokinetics at steady state was investigated, showed that the pharmacokinetics of rasagiline were not affected by concomitant administration of LD/CD. Effect of Other Drugs on the Metabolism of Rasagiline In vitro metabolism studies showed that CYP1A2 was the major enzyme responsible for the metabolism of rasagiline. There is the potential for inhibitors of this enzyme to alter rasagiline clearance when coadministered [see Dosage and Administration (2.2) and Warnings and Precautions (5.4)]. Ciprofloxacin: When ciprofloxacin, an inhibitor of CYP1A2, was administered to healthy volunteers (n=12) at 500 mg (BID) with rasagiline at 2 mg/day, the AUC of rasagiline increased by 83% and there was no change in the elimination half life [see Dosage and Administration (2.2) and Warnings and Precautions (5.4)]. Theophylline: Coadministration of rasagiline 1 mg/day and theophylline, a substrate of CYP1A2, up to 500 mg twice daily to healthy subjects (n=24) did not affect the pharmacokinetics of either drug. Antidepressants: Severe CNS toxicity (occasionally fatal) associated with hyperpyrexia as part of a serotonin syndrome, has been reported with combined treatment of an antidepressant (e.g., from one of many classes including tricyclic or tetracyclic antidepressants, SSRIs, SNRIs, triazolopyridine antidepressants) and nonselective MAOI or a selective MAO-B inhibitor [see Warnings and Precautions (5.2)]. Effect of Rasagiline on Other Drugs No additional in vivo trials have investigated the effect of rasagiline on other drugs metabolized by the cytochrome P450 enzyme system. In vitro studies showed that rasagiline at a concentration of 1 mcg/mL (equivalent to a level that is 160 times the average C max ~ 5.9 to 8.5 ng/mL in Parkinson’s disease patients after 1 mg rasagiline multiple dosing) did not inhibit cytochrome P450 isoenzymes, CYP1A2, CYP2A6, CYP2C9, CYP2C19, CYP2D6, CYP2E1, CYP3A4 and CYP4A. These results indicate that rasagiline is unlikely to cause any clinically significant interference with substrates of these enzymes.

Carcinogenesis And Mutagenesis And Impairment Of Fertility
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Two-year carcinogenicity studies were conducted in mice at oral doses of 0, 1, 15, and 45 mg/kg/day and in rats at oral doses of 0.3, 1, and 3 mg/kg/day (males) or 0, 0.5, 2, 5, and 17 mg/kg/day (females). In rats, there was no increase in tumors at any dose tested. Plasma exposures (AUC) at the highest dose tested were approximately 33 and 260 times, in male and female rats, respectively, that in humans at the maximum recommended human dose (MRHD) of 1 mg/day. In mice, there was an increase in lung tumors (combined adenomas/carcinomas) at 15 and 45 mg/kg in males and females. At the lowest dose tested, plasma AUCs were approximately 5 times those expected in humans at the MRHD. The carcinogenic potential of rasagiline administered in combination with levodopa/carbidopa has not been examined. Mutagenesis Rasagiline was reproducibly clastogenic in in vitro chromosomal aberration assays in human lymphocytes in the presence of metabolic activation and was mutagenic and clastogenic in the in vitro mouse lymphoma tk assay in the absence and presence of metabolic activation. Rasagiline was negative in the in vitro bacterial reverse mutation (Ames) assay and in the in vivo micronucleus assay in mice. Rasagiline was also negative in the in vivo micronucleus assay in mice when administered in combination with levodopa/carbidopa. Impairment of Fertility Rasagiline had no effect on mating performance or fertility in rats treated prior to and throughout the mating period and continuing in females through gestation day 17 at oral doses of up to 3 mg/kg/day (approximately 30 times the plasma AUC in humans at the MRHD). The effect of rasagiline administered in combination with levodopa/carbidopa on mating and fertility has not been examined.

Information For Patients
17 PATIENT COUNSELING INFORMATION Hypertension Advise patients that treatment with recommended doses of rasagiline tablets may be associated with elevations of blood pressure. Tell patients who experience elevation of blood pressure while taking rasagiline tablets to contact their healthcare provider. The risk of using higher than recommended daily doses of rasagiline tablets should be explained, and a brief description of the tyramine associated hypertensive reaction provided. Advise patients to avoid certain foods (e.g., aged cheese) containing a very large amount of tyramine while taking recommended doses of rasagiline tablets because of the potential for large increases in blood pressure. If patients eat foods very rich in tyramine and do not feel well soon after eating, they should contact their healthcare provider [see Warnings and Precautions ( 5.1 )] . Serotonin Syndrome Tell patients to inform their physician if they are taking, or planning to take, any prescription or over-the-counter drugs, especially antidepressants and over-the-counter cold medications, since there is a potential for interaction with rasagiline tablets. Because patients should not use meperidine or certain other analgesics with rasagiline tablets, they should contact their healthcare provider before taking analgesics [see Contraindications ( 4 ) and Warnings and Precautions ( 5.2 )] . Falling Asleep During Activities of Daily Living and Somnolence Advise and alert patients about the potential for sedating effects associated with rasagiline tablets and other dopaminergic medications, including somnolence and particularly to the possibility of falling asleep while engaged in activities of daily living. Because somnolence can be a frequent adverse reaction with potentially serious consequences, patients should neither drive a car nor engage in other potentially dangerous activities until they have gained sufficient experience with rasagiline tablets and other dopaminergic medications to gauge whether or not it affects their mental and/or motor performance adversely. Advise patients that if increased somnolence or new episodes of falling asleep during activities of daily living (e.g., watching television, passenger in a car, etc.) are experienced at any time during treatment, they should not drive or participate in potentially dangerous activities until they have contacted their physician. Patients should not drive, operate machinery, or work at heights during treatment if they have previously experienced somnolence and/or have fallen asleep without warning prior to use of rasagiline tablets. Because of possible additive effects, advise patients to exercise caution when patients are taking other sedating medications, alcohol, or other central nervous system depressants (e.g., benzodiazepines, antipsychotics, antidepressants) in combination with rasagiline tablets or when taking concomitant medications that increase plasma levels of rasagiline (e.g., ciprofloxacin) [see Warnings and Precautions ( 5.3 )] . Ciprofloxacin or Other CYP1A2 Inhibitors Inform patients that they should contact their healthcare provider of rasagiline tablets if they take ciprofloxacin or a similar drug that could increase blood levels of rasagiline because of the need to adjust the dose of rasagiline tablets [see Dosage and Administration ( 2.2 ) and Warnings and Precautions ( 5.4 )] . Hepatic Impairment Tell patients who have hepatic problems to contact their healthcare provider regarding possible changes in rasagiline tablets dosing [see Warnings and Precautions ( 5.5 )] . Hypotension / Orthostatic Hypotension Patients should be advised that they may develop orthostatic hypotension with or without symptoms such as dizziness, nausea, syncope, and sometimes sweating. Hypotension and/or orthostatic symptoms may occur more frequently during initial therapy or with an increase in dose at any time (cases have been seen after weeks of treatment). Accordingly, patients should be cautioned against standing up rapidly after sitting or lying down, especially if they have been doing so for prolonged periods, and especially, at the initiation of treatment with rasagiline tablets [see Warnings and Precautions ( 5.6 )] . Dyskinesia Advise patients taking rasagiline tablets as adjunct to levodopa that there is a possibility of dyskinesia or increased dyskinesia [see Warnings and Precautions ( 5.7 )] . Hallucinations / Psychotic-Like Behavior Inform patients that hallucinations or other manifestations of psychotic-like behavior can occur when taking rasagiline tablets. Advise patients that, if they have a major psychotic disorder, that rasagiline tablets should not ordinarily be used because of the risk of exacerbating the psychosis. Patients with a major psychotic disorder should also be aware that many treatments for psychosis may decrease the effectiveness of rasagiline tablets [see Warnings and Precautions ( 5.8 )] . Impulse Control/Compulsive Behaviors Advise patients that they may experience intense urges to gamble, increased sexual urges, other intense urges, and the inability to control these urges while taking one or more of the medications that increase central dopaminergic tone and that are generally used for the treatment of Parkinson’s disease (including rasagiline tablets). Although it is not proven that the medications caused these events, these urges were reported to have stopped in some cases when the dose was reduced or the medication was stopped. Prescribers should ask patients about the development of new or increased gambling urges, sexual urges, or other urges while being treated with rasagiline tablets. Patients should inform their physician if they experience new or increased gambling urges, increased sexual urges, or other intense urges while taking rasagiline tablets. Physicians should consider dose reduction or stopping the medication if a patient develops such urges while taking rasagiline tablets [see Warnings and Precautions ( 5.9 )] . Withdrawal-Emergent Hyperpyrexia and Confusion Tell patients to contact their healthcare provider if they wish to discontinue rasagiline tablets [see Warnings and Precautions ( 5.10 )] . Missing Dose Instruct patients to take rasagiline tablets as prescribed. If a dose is missed, the patient should not double-up the dose of rasagiline tablets. The next dose should be taken at the usual time on the following day. Pregnancy Advise patients to notify their healthcare provider if they are pregnant or plan to become pregnant [see Use in Specific Populations ( 8.1 )] .
Clinical Studies
14 CLINICAL STUDIES The effectiveness of rasagiline for the treatment of Parkinson’s disease was established in four 18 to 26 week, randomized, placebo-controlled trials, as initial monotherapy or adjunct therapy. 14.1 Monotherapy Use of Rasagiline Study 1 was a double-blind, randomized, fixed-dose parallel group, 26 week study in early Parkinson’s disease patients not receiving any concomitant dopaminergic therapy at the start of the study. The majority of the patients were not treated with medications for Parkinson’s disease before receiving rasagiline. In Study 1, 404 patients were randomly assigned to receive placebo (138 patients), rasagiline 1 mg/day (134 patients) or rasagiline 2 mg/day (132 patients). Patients were not allowed to take levodopa, dopamine agonists, selegiline, or amantadine, but could take stable doses of anticholinergic medication, if necessary. The average Parkinson’s disease duration was approximately 1 year (range 0 to 11 years). The primary measure of effectiveness was the change from baseline in the total score of the Unified Parkinson’s Disease Rating Scale (UPDRS), [mentation (Part I) + activities of daily living (ADL) (Part II) + motor function (Part III)]. The UPDRS is a multi-item rating scale that measures the ability of a patient to perform mental and motor tasks as well as activities of daily living. A reduction in the score represents improvement and a beneficial change from baseline appears as a negative number. Rasagiline (1 or 2 mg once daily) was superior to placebo on the primary measure of effectiveness in patients receiving six months of treatment and not on dopaminergic therapy. The effectiveness of rasagiline 1 mg and 2 mg was comparable. Table 4 shows the results of Study 1. There were no differences in effectiveness based on age or gender between rasagiline 1 mg/day and placebo. Table 4: Change in Total UPDRS Score in Study 1 Baseline score Change from baseline to termination score p-value vs. placebo Placebo 24.5 3.9 --- Rasagiline 1 mg 24.7 0.1 0.0001 Rasagiline 2 mg 25.9 0.7 0.0001 14.2 Adjunct Use of Rasagiline Study 2 was a double-blind, randomized, placebo-controlled, parallel group, 18-week study, investigating rasagiline 1 mg as adjunct therapy to dopamine agonists without levodopa. Patients were on a stable dose of dopamine agonist (ropinirole, mean 8 mg/day or pramipexole, mean 1.5 mg/day) therapy for ≥ 30 days, but at doses not sufficient to control Parkinson’s disease symptoms. In Study 2, 321 patients randomly received placebo (162 patients) or rasagiline 1 mg/day (159 patients) and had a post-baseline assessment. The average Parkinson’s disease duration was approximately 2 years (range 0.1 to 14.5 years). The primary measure of effectiveness was the change from baseline in the total score of the Unified Parkinson’s Disease Rating Scale (UPDRS) [mentation (Part I) + activities of daily living (ADL) (Part II) + motor function (Part III)]. In Study 2, rasagiline 1 mg was superior to placebo on the primary measure of effectiveness (see Table 5). Table 5: Change in Total UPDRS Score in Study 2 Baseline score Change from baseline to termination score* p-value vs. placebo Placebo 29.8 -1.2 --- Rasagiline 1 mg 32.1 -3.6 0.012 * A negative change from baseline indicates improvement in the UPDRS Secondary outcome assessment of the individual subscales of the UPDRS indicates that the UPDRS Part III motor subscale was primarily responsible for the overall rasagiline effect on the UPDRS score (see Table 6).

Study 3 was conducted in North America (U.S. and Canada) and compared rasagiline 0.5 mg and 1 mg daily to placebo. Study 4 was conducted outside of North America in Europe, Argentina, and Israel, and compared rasagiline 1 mg daily to placebo. Patients had Parkinson’s disease for an average of 9 years (range 5 months to 33 years), had taken levodopa for an average of 8 years (range 5 months to 32 years), and had motor fluctuations for approximately 3 to 4 years (range 1 month to 23 years). Patients kept home Parkinson’s disease diaries just prior to baseline and at specified intervals during the trial. Diaries recorded one of the following four conditions for each half-hour interval over a 24 hour period: “ON” (period of relatively good function and mobility) as either “ON” with no dyskinesia or without troublesome dyskinesia, or “ON” with troublesome dyskinesia, “OFF” (period of relatively poor function and mobility) or asleep. “Troublesome” dyskinesia is defined as dyskinesia that interferes with the patient’s daily activity. All patients had inadequate control of their motor symptoms with motor fluctuations typical of advanced stage disease despite receiving levodopa/decarboxylase inhibitor. The average dose of levodopa taken with a decarboxylase inhibitor was approximately 700 to 800 mg (range 150 to 3000 mg/day). Patients continued their stable doses of additional anti-PD medications at entry into the trials. Approximately 65% of patients in both studies were also taking a dopamine agonist. In the North American study (Study 3), approximately 35% of patients took entacapone with levodopa/decarboxylase inhibitor. The majority of patients taking entacapone were also taking a dopamine agonist. In Study 3 and Study 4, the primary measure of effectiveness was the change in the mean number of hours spent in the “OFF” state at baseline compared to the mean number of hours spent in the “OFF” state during the treatment period. In Study 3, patients were randomly assigned to receive placebo (159 patients), rasagiline 0.5 mg/day (164 patients), or rasagiline 1 mg/day (149 patients) for 26 weeks. Patients averaged 6 hours daily in the “OFF” state at baseline as confirmed by home diaries. In Study 4, patients were randomly assigned to receive placebo (229 patients), rasagiline 1 mg/day (231 patients) or a COMT inhibitor (active comparator), taken along with scheduled doses of levodopa/decarboxylase inhibitor (227 patients) for 18 weeks. Patients averaged 5.6 hours daily in the “OFF” state at baseline as confirmed by home diaries. In Study 3 and Study 4, rasagiline 1 mg once daily reduced “OFF” time compared to placebo when added to levodopa in patients experiencing motor fluctuations (Tables 7 and 8). The lower dose (0.5 mg) of rasagiline also significantly reduced “OFF” time (Table 7), but had a numerically smaller effect than the 1 mg dose of rasagiline. In Study 4, the active comparator also reduced “OFF” time when compared to placebo. Table 7: Change in mean total daily "OFF" time in Study 3 Baseline (hours) Change from baseline to treatment period (hours) p-value vs. placebo Placebo 6 -0.9 --- Rasagiline 0.5 mg 6 -1.4 0.0199 Rasagiline 1 mg 6.3 -1.9 <0.0001 Table 8: Change in mean total daily "OFF" time in Study 4 Baseline (hours) Change from baseline to treatment period (hours) p-value vs. placebo Placebo 5.5 -0.4 --- Rasagiline 1 mg 5.6 -1.2 0.0001 In Study 3 and Study 4, dose reduction of levodopa was allowed within the first 6 weeks, if dopaminergic side effects developed including dyskinesia or hallucinations. In Study 3, the levodopa dose was reduced in 8% of patients in the placebo group and in 16% and 17% of patients in the 0.5 mg/day and 1 mg/day rasagiline groups, respectively. When levodopa was reduced, the dose was reduced by 7%, 9%, and 13% in the placebo, 0.5 mg/day, and 1 mg/day groups, respectively. In Study 4, levodopa dose reduction occurred in 6% of patients in the placebo group and in 9% in the rasagiline 1 mg/day groups, respectively. When levodopa was reduced, it was reduced by 13% and 11% in the placebo and the rasagiline groups, respectively. There were no differences in effectiveness based on age or gender between rasagiline 1 mg per day and placebo. Several secondary outcome assessments in the two studies showed statistically significant improvements with rasagiline. These included effects on the activities of daily living (ADL) subscale of the UPDRS performed during an “OFF” period and the motor subscale of the UPDRS performed during an “ON” period. In both scales, a negative response represents improvement. Tables 9 and 10 show these results for Studies 3 and 4.

Pregnancy
8.1 Pregnancy Risk Summary There are no adequate data on the developmental risks associated with the use of rasagiline in pregnant women. In animal studies, oral administration of rasagiline to rats during gestation and lactation resulted in decreased survival and reduced body weight in the offspring at doses similar to those used clinically. When administered to pregnant animals in combination with levodopa/carbidopa, there were increased incidences of fetal skeletal variations in rats and increases in embryofetal death and cardiovascular abnormalities in rabbits [see Data] . In the US 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 background risks of major birth defects and miscarriage for the indicated population is unknown. Data Animal Data In a combined mating/fertility and embryofetal development study in pregnant rats, no effect on embryofetal development was observed at oral doses up to 3 mg/kg/day (approximately 30 times the plasma exposure (AUC) in humans at the maximum recommended human dose [MRHD, 1 mg/day]). In pregnant rabbits administered rasagiline throughout the period of organogenesis at oral doses of up to 36 mg/kg/day, no developmental toxicity was observed. At the highest dose tested, the plasma AUC was approximately 800 times that in humans at the MRHD. In pregnant rats administered rasagiline (0, 0.1, 0.3, 1 mg/kg/day) orally during gestation and lactation, offspring survival was decreased and offspring body weight was reduced at 0.3 mg/kg/day and 1 mg/kg/day (10 and 16 times the plasma AUC in humans at the MRHD). The no-effect dose (0.1 mg/kg) for adverse developmental effects is similar to the MRHD on a body surface area (mg/m 2 ) basis. The effect of rasagiline on physical and behavioral development was not adequately assessed in this study. Rasagiline may be given as an adjunct therapy to levodopa/carbidopa treatment. In pregnant rats administered rasagiline (0, 0.1, 0.3, 1 mg/kg/day) and levodopa/carbidopa (80/20 mg/kg/day) (alone and in combination) orally throughout the period of organogenesis, there was an increased incidence of fetal skeletal variations in fetuses from rats treated with rasagiline in combination with levodopa/carbidopa at 1/80/20 mg/kg/day (approximately 8 times the rasagiline plasma AUC in humans at the MRHD and similar to the MRHD of levodopa/carbidopa [800/200 mg/day] on a mg/m 2 basis). In pregnant rabbits dosed orally throughout the period of organogenesis with rasagiline alone (3 mg/kg) or in combination with levodopa/carbidopa (rasagiline: 0.1, 0.6, 1.2 mg/kg, levodopa/carbidopa: 80/20 mg/kg/day), an increase in embryofetal death was noted at rasagiline doses of 0.6 and 1.2 mg/kg/day when administered in combination with levodopa/carbidopa (approximately 7 and 13 times, respectively, the rasagiline plasma AUC in humans at the MRHD). There was an increase in cardiovascular abnormalities with levodopa/carbidopa alone (similar to the MRHD on a mg/m 2 basis) and to a greater extent when rasagiline (at all doses; 1 to 13 times the rasagiline plasma AUC in humans at the MRHD) was administered in combination with levodopa/carbidopa.

In pregnant rats administered rasagiline (0, 0.1, 0.3, 1 mg/kg/day) and levodopa/carbidopa (80/20 mg/kg/day) (alone and in combination) orally throughout the period of organogenesis, there was an increased incidence of fetal skeletal variations in fetuses from rats treated with rasagiline in combination with levodopa/carbidopa at 1/80/20 mg/kg/day (approximately 8 times the rasagiline plasma AUC in humans at the MRHD and similar to the MRHD of levodopa/carbidopa [800/200 mg/day] on a mg/m 2 basis). In pregnant rabbits dosed orally throughout the period of organogenesis with rasagiline alone (3 mg/kg) or in combination with levodopa/carbidopa (rasagiline: 0.1, 0.6, 1.2 mg/kg, levodopa/carbidopa: 80/20 mg/kg/day), an increase in embryofetal death was noted at rasagiline doses of 0.6 and 1.2 mg/kg/day when administered in combination with levodopa/carbidopa (approximately 7 and 13 times, respectively, the rasagiline plasma AUC in humans at the MRHD). There was an increase in cardiovascular abnormalities with levodopa/carbidopa alone (similar to the MRHD on a mg/m 2 basis) and to a greater extent when rasagiline (at all doses; 1 to 13 times the rasagiline plasma AUC in humans at the MRHD) was administered in combination with levodopa/carbidopa. 8.2 Lactation Risk Summary There are no data on the presence of rasagiline in human milk or the effects on the breastfed infant. In rats, rasagiline was shown to inhibit prolactin secretion. The clinical relevance in humans is unknown, and there are no data on the effects of rasagiline on prolactin secretion or milk production in humans. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for rasagiline and any potential adverse effects on the breastfed infant from rasagiline or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness in pediatric patients have not been established. 8.5 Geriatric Use Approximately half of patients in clinical trials were 65 years and over. There were no significant differences in the safety profile of the geriatric and nongeriatric patients. 8.6 Hepatic Impairment Rasagiline plasma concentration may be increased in patients with mild (up to 2 fold, Child-Pugh score 5 to 6), moderate (up to 7 fold, Child-Pugh score 7 to 9), and severe (Child-Pugh score 10 to 15) hepatic impairment. Patients with mild hepatic impairment should not exceed a dose of 0.5 mg/day. Rasagiline should not be used in patients with moderate or severe hepatic impairment [see Dosage and Administration ( 2.3 ), Warnings and Precautions ( 5.5 ) and Clinical Pharmacology ( 12.3 )] . 8.7 Renal Impairment Dose adjustment of rasagiline is not required for patients with mild or moderate renal impairment because rasagiline plasma concentrations are not increased in patients with moderate renal impairment. Rasagiline has not been studied in patients with severe renal impairment [see Clinical Pharmacology ( 12.3 )] .
