APOKYN

6 ADVERSE REACTIONS The following serious adverse reactions are discussed in more detail in the Warnings and Precautions section of labeling: Serious Adverse Reactions After Intravenous Administration [see Warnings and Precautions (5.1) ] Nausea and Vomiting [see Warnings and Precautions (5.2) ] Falling Asleep During Activities of Daily Living and Somnolence [see Warnings and Precautions (5.3) ] Syncope/Hypotension/Orthostatic Hypotension [see Warnings and Precautions (5.4) ] Falls [see Warnings and Precautions (5.5) ] Hallucinations/Psychotic-Like Behavior [see Warnings and Precautions (5.6) ] Dyskinesias [see Warnings and Precautions (5.7) ] Hemolytic Anemia [see Warnings and Precautions (5.8) Impulse Control/Compulsive Behaviors [see Warnings and Precautions (5.9) ] Coronary Events [see Warnings and Precautions (5.10) ] QTc Prolongation and Potential for Proarrhythymic Effects [see Warnings and Precautions (5.11) ] Withdrawal-Emergent Hyperpyrexia and Confusion [see Warnings and Precautions (5.12) ] Hypersensitivity [see Warnings and Precautions (5.13) ] Fibrotic Complications [see Warnings and Precautions (5.14) ] Priapism [see Warnings and Precautions (5.15) ] Most common adverse reactions (incidence at least 10% greater on APOKYN than on placebo) were yawning, drowsiness/somnolence, dyskinesias, dizziness/postural hypotension, rhinorrhea, nausea and/or vomiting, hallucination/confusion, and edema/swelling of extremities ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact MDD US Operations, LLC at 1-877-727-6596 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, the incidence of adverse reactions (number of unique patients experiencing an adverse reaction associated with treatment per total number of patients treated) 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 incidence of adverse reactions observed in practice. In placebo-controlled trials, most patients received only one subcutaneous dose of APOKYN. All patients received concomitant levodopa and 86% received a concomitant dopamine agonist. All patients had some degree of spontaneously occurring periods of hypomobility ("off episodes") at baseline. The most common adverse reactions (APOKYN incidence at least 10% greater than placebo incidence) observed in a placebo-controlled trial were yawning, drowsiness/somnolence, dyskinesias, dizziness/postural hypotension, rhinorrhea, nausea and/or vomiting, hallucination/confusion, and edema/swelling of extremities. Table 1 presents the most common adverse reactions reported by APOKYN-naïve Parkinson's disease patients who were enrolled in a randomized placebo-controlled, parallel group trial and who were treated for up to 4 weeks (Study 1) [see Clinical Studies (14) ] . Individual APOKYN doses in this trial ranged from 2 mg to 10 mg, and were titrated to achieve tolerability and control of symptoms.

In addition to those in Table 1, the most common adverse reactions in pooled APOKYN trials (occurring in at least 5% of the patients) in descending order were injection site reaction, fall, arthralgia, insomnia, headache, depression, urinary tract infection, anxiety, congestive heart failure, limb pain, back pain, Parkinson's disease aggravated, pneumonia, confusion, sweating increased, dyspnea, fatigue, ecchymosis, constipation, diarrhea, weakness, and dehydration. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of APOKYN. 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. Hematologic and Lymphatic Systems: hemolytic anemia [see Warnings and Precautions (5.8) ]

4 CONTRAINDICATIONS APOKYN is contraindicated in patients: Using concomitant drugs of the 5HT 3 antagonist class including antiemetics (e.g., ondansetron, granisetron, dolasetron, palonosetron) and alosetron [see Drug Interactions (7.1) ] . There have been reports of profound hypotension and loss of consciousness when APOKYN was administered with ondansetron. With hypersensitivity/allergic reaction to apomorphine or to any of the excipients of APOKYN, including a sulfite (i.e., sodium metabisulfite). Angioedema or anaphylaxis may occur [see Warnings and Precautions (5.13) ]. Concomitant use of APOKYN with 5HT 3 antagonists, including antiemetics (e.g., ondansetron, granisetron, dolasetron, palonosetron) and alosetron, is contraindicated ( 4 ) Hypersensitivity to apomorphine, its excipients or sodium metabisulfite ( 4 , 5.13 )

11 DESCRIPTION APOKYN (apomorphine hydrochloride injection) contains apomorphine hydrochloride, a non-ergoline dopamine agonist. Apomorphine hydrochloride is chemically designated as 6aβ-Aporphine-10,11-diol hydrochloride hemihydrate with a molecular formula of C 17 H 17 NO 2 ∙ HCl ∙ ½ H 2 O. Its structural formula and molecular weight are: Figure 1: Structural Formula and Molecular Weight of Apomorphine M.W. 312.79 Apomorphine hydrochloride appears as minute, white or grayish-white glistening crystals or as white powder that is soluble in water at 80°C. APOKYN is a clear, colorless, sterile solution for subcutaneous injection and is available in 3 mL (30 mg) multi-dose cartridges. Each mL of solution contains 10 mg of apomorphine hydrochloride, USP as apomorphine hydrochloride hemihydrate (equivalent to 8.55 mg apomorphine), 1 mg of sodium metabisulfite, NF and 5 mg of benzyl alcohol, NF (preservative) in water for injection, USP. In addition, each mL of solution may contain sodium hydroxide, NF and/or hydrochloric acid, NF to adjust the pH of the solution. Figure 1

2 DOSAGE AND ADMINISTRATION For subcutaneous use only ( 2.1 ) Always express APOKYN dose in mL to minimize dosing errors ( 2.1 ) The starting dose of APOKYN is 0.1 mL (1mg) to 0.2 mL (2 mg); give the first dose under medical supervision; titrate the dose to effect and tolerance; the maximum recommended dose is 0.6 mL (6 mg) ( 2.3 ) Treatment with trimethobenzamide is recommended, starting 3 days prior to the first dose of APOKYN. Treatment with trimethobenzamide should only be continued as long as necessary to control nausea and vomiting, and generally no longer than two months ( 2.2 , 5.2 , 6.1 , 17 ) APOKYN doses must be separated by at least 2 hours ( 2.5 ) Renal impairment: reduce test dose, and reduce starting dose to 0.1 mL (1 mg) ( 2.4 , 8.6 , 12.3 ) 2.1 Important Administration Instructions APOKYN is indicated for subcutaneous administration only [see Warnings and Precautions (5.1) ] and only by a multiple-dose APOKYN Pen with supplied cartridges. The initial dose and dose titrations should be performed by a healthcare provider. Blood pressure and pulse should be measured in the supine and standing position before and after dosing. A caregiver or patient may administer APOKYN if a healthcare provider determines that it is appropriate. Instruct patients to follow the directions provided in the Patients Instructions For Use. Because the APOKYN Pen has markings in milliliters (mL), the prescribed dose of APOKYN should be expressed in mL to avoid confusion. Visually inspect the APOKYN drug product through the viewing window for particulate matter and discoloration prior to administration. The solution should not be used if discolored (it should be colorless), or cloudy, or if foreign particles are present. Rotate the injection site and use proper aseptic technique [see How Supplied/Storage and Handling (16) and Patient Counseling Information (17) ] . 2.2 Premedication and Concomitant Medication Because of the incidence of nausea and vomiting with APOKYN, it is recommended that treatment with trimethobenzamide 300 mg three times a day be started 3 days prior to the initial dose of APOKYN [see Warnings and Precautions (5.2) ] . Alternatively, consider starting APOKYN therapy at 0.1 mL (1 mg) and titrate based upon effectiveness and tolerance. If trimethobenzamide is used, it should only be continued as long as necessary to control nausea and vomiting, and generally no longer than two months after initiation of treatment with APOKYN, as trimethobenzamide increases the incidence of somnolence, dizziness, and falls in patients treated with APOKYN [see Warnings and Precautions (5.2) ] . Based on reports of profound hypotension and loss of consciousness when apomorphine was administered with ondansetron, the concomitant use of apomorphine with drugs of the 5HT 3 antagonist class including antiemetics (for example, ondansetron, granisetron, dolasetron, palonosetron) and alosetron are contraindicated [see Contraindications (4) ]. 2.3 Dosing Information The recommended starting dose of APOKYN is 0.1 mL (1 mg) to 0.2 mL (2 mg). Titrate on the basis of effectiveness and tolerance, up to a maximum recommended dose of 0.6 mL (6 mg) [see Clinical Studies (14) ] . There is no evidence from controlled trials that doses greater than 0.6 mL (6 mg) gave an increased effect Reference ID: 5002510 - 3 - and therefore, individual doses above 0.6 mL (6 mg) are not recommended. The average frequency of dosing in the development program was 3 times per day. There is limited experience with single doses greater than 0.6 mL (6 mg), dosing more than 5 times per day and with total daily doses greater than 2 mL (20 mg). Begin dosing when patients are in an "off" state. The initial test dose should be a 0.1 mL (1 mg) or 0.2 mL (2 mg) test dose in a setting where medical personnel can closely monitor blood pressure and pulse. Both supine and standing blood pressure and pulse should be checked pre-dose and at 20 minutes, 40 minutes, and 60 minutes post-dose (and after 60 minutes, if there is significant hypotension at 60 minutes). Patients who develop clinically significant orthostatic hypotension in response to this test dose of APOKYN should not be considered candidates for treatment with APOKYN. If the patient tolerates the initial test dose, and responds adequately, the starting dose should be the same as the test dose, used on an as needed basis to treat recurring "off" episodes. If needed, the dose can be increased in 0.1 mL (1 mg) increments every few days on an outpatient basis. The general principle guiding subsequent dosing (described in detail below) is to determine that the patient needs and can tolerate a higher test dose, 0.3 mL or 0.4 mL (3 mg or 4 mg, respectively) under close medical supervision. A trial of outpatient dosing may follow (periodically assessing both efficacy and tolerability), using a dose 0.1 mL (1 mg) lower than the tolerated test dose. If the patient tolerates a 0.1 mL (1 mg) test dose but does not respond adequately, a test dose of 0.2 mL (2 mg) may be administered under medical supervision, at least 2 hours after the initial test dose, at the next observed "off" period. If the patient tolerates a 0.2 mL (2 mg) test dose but does not respond adequately, a test dose of 0.4 mL (4 mg) may be administered under medical supervision, at least 2 hours after the initial test dose, at the next observed "off" period. Patients who do not tolerate 0.2 mL (2 mg) may need to be titrated slowly. If the patient tolerates and responds to a test dose of 0.4 mL (4 mg), the initial maintenance dose should be 0.3 mL (3 mg) used on an as needed basis to treat recurring "off" episodes as an outpatient. If needed, the dose can be increased in 0.1 mL (1 mg) increments every few days on an outpatient basis. If the patient does not tolerate a test dose of 0.4 mL (4 mg), a test dose of 0.3 mL (3 mg) may be administered during a separate "off" period under medical supervision, at least 2 hours after the previous dose. If the patient tolerates the 0.3 mL (3 mg) test dose, the initial maintenance dose should be 0.2 mL (2 mg) used on an as needed basis to treat existing "off" episodes. If needed, and the 0.2 mL (2 mg) dose is tolerated, the dose can be increased to 0.3 mL (3 mg) after a few days. In such a patient, the dose should ordinarily not be increased to 0.4 mL (4 mg) on an outpatient basis. 2.4 Dosing in Patients with Renal Impairment For patients with mild and moderate renal impairment, the test dose and starting dose should be reduced to 0.1 mL (1 mg) [see Clinical Pharmacology (12.3) and Use in Specific Populations (8.6) ] . 2.5 Re-treatment and Interruption in Therapy If a single dose of APOKYN is ineffective for a particular "off" period, a second dose should not be given for that "off" episode. The efficacy of the safety of administering a second dose for a single "off" episode has not been studied systematically. Do not administer a repeat dose of APOKYN sooner than 2 hours after the last dose. Patients who have an interruption in therapy of more than a week should be restarted on a 0.2 mL (2 mg) dose and gradually titrated to effect and tolerability.

1 INDICATIONS AND USAGE APOKYN (apomorphine hydrochloride injection) is indicated for the acute, intermittent treatment of hypomobility, "off" episodes ("end-of-dose wearing off" and unpredictable "on/off" episodes) in patients with advanced Parkinson's disease. APOKYN has been studied as an adjunct to other medications [see Clinical Studies (14) ] . APOKYN is a non-ergoline dopamine agonist indicated for the acute, intermittent treatment of hypomobility, "off" episodes ("end-of-dose wearing off" and unpredictable "on/off" episodes) associated with advanced Parkinson's disease ( 1 )

9.2 Abuse In premarketing clinical experience, APOKYN did not reveal any tendency for a withdrawal syndrome or any drug-seeking behavior. However, there are rare postmarketing reports of abuse of medications containing APOKYN or levodopa. In general, these reports consist of patients taking increasing doses of medication in order to achieve a euphoric state.

9 DRUG ABUSE AND DEPENDENCE 9.2 Abuse In premarketing clinical experience, APOKYN did not reveal any tendency for a withdrawal syndrome or any drug-seeking behavior. However, there are rare postmarketing reports of abuse of medications containing APOKYN or levodopa. In general, these reports consist of patients taking increasing doses of medication in order to achieve a euphoric state.

10 OVERDOSAGE A 62-year-old man accidentally injected 25 mg of APOKYN subcutaneously. After 3 minutes, the patient felt nauseated and lost consciousness for 20 minutes. Afterwards, he was alert with a heart rate 40/minute and a supine blood pressure of 90/50. He recovered completely within an hour.

7 DRUG INTERACTIONS Concomitant use of antihypertensive medications and vasodilators: increased risk for hypotension, myocardial infarction, pneumonia, falls, and injuries ( 7.2 ) Dopamine antagonists such as neuroleptics or metoclopramide, may diminish the effectiveness of APOKYN ( 7.4 ) 7.1 5HT 3 Antagonists Based on reports of profound hypotension and loss of consciousness when APOKYN was administered with ondansetron, the concomitant use of APOKYN with 5HT 3 antagonists including antiemetics (for example, ondansetron, granisetron, dolasetron, palonosetron) and alosetron, is contraindicated. 7.2 Antihypertensive Medications and Vasodilators In clinical studies, the following adverse events were experienced more commonly in patients receiving concomitant antihypertensive medications or vasodilators (n=94) than in patients not receiving these medications (n=456): hypotension (10% vs 4%) [see Warnings and Precautions (5.4) ] , myocardial infarction (3% vs 1%), serious pneumonia (5% vs 3%), serious falls (9% vs 3%), and bone and joint injuries (6% vs 2%). Some of the events may be related to the increased incidence of hypotension in patients receiving concomitant antihypertensive medications or vasodilators [see Warnings and Precautions (5.4 , 5.5) ] . Concomitant administration of 0.4 mg sublingual nitroglycerin with APOKYN in healthy subjects causes greater decreases in blood pressure compared to APOKYN alone. When nitroglycerin and APOKYN were concomitantly administered to healthy subjects, the mean largest decrease (the mean of each subject's largest drop in blood pressure measured within the 6-hour period following administration of APOKYN) in supine systolic and diastolic blood pressure (measured over 6 hours) was 9.7 mm Hg and 9.3 mm Hg, respectively [see Clinical Pharmacology (12.3) ]. The mean largest decrease in standing systolic and diastolic blood pressure was 14.3 mm Hg and 13.5 mm Hg, respectively. Some individuals experienced very large decreases in standing systolic and diastolic blood pressure, up to a maximum decrease of 65 mm Hg and 43 mm Hg, respectively. In comparison, the mean largest decrease in supine systolic and diastolic blood pressure when APOKYN was administered alone was 6.1 mm Hg and 7.3 mm Hg, respectively, and in standing systolic and diastolic blood pressure was 6.7 mm Hg and 8.4 mm Hg, respectively. Patients taking APOKYN should lie down before and after taking sublingual nitroglycerin [see Warnings and Precautions (5.4) ]. 7.3 Alcohol Concomitant administration of high dose (0.6 g/kg) or low dose (0.3 g/kg) ethanol with APOKYN in healthy subjects causes greater decreases in blood pressure compared to APOKYN alone. When high dose ethanol and APOKYN were concomitantly administered to healthy subjects, the mean largest decrease (the mean of each subject's largest drop in blood pressure measured within the 6-hour period following administration of APOKYN) for supine systolic and diastolic blood pressure was 9.1 mm Hg and 10.5 mm Hg, respectively [see Clinical Pharmacology (12.3) ]. The mean largest standing systolic and diastolic blood pressure decrease was 11.3 mm Hg and 12.6 mm Hg, respectively. In some individuals, the decrease was as high as 61 mm Hg and 51 mm Hg, respectively, for standing systolic and diastolic blood pressure. When low dose ethanol and APOKYN were concomitantly administered, the mean largest decrease in supine systolic and diastolic blood pressure was 10.2 mm Hg and 9.9 mm Hg, respectively. The mean largest decrease in standing systolic and diastolic blood pressure was 8.4 mm Hg and 7.1 mm Hg, respectively. In comparison, the mean largest decrease in supine systolic and diastolic blood pressure when APOKYN was administered alone was 6.1 mm Hg and 7.3 mm Hg, respectively, and in standing systolic and diastolic blood pressure was 6.7 mm Hg 8.4 mm Hg, respectively. Patients should avoid drinking alcohol after using APOKYN [see Warnings and Precautions (5.4) ]. 7.4 Dopamine Antagonists Since APOKYN is a dopamine agonist, it is possible that concomitant use of dopamine antagonists, such as the neuroleptics (phenothiazines, butyrophenones, thioxanthenes) or metoclopramide, may diminish the effectiveness of APOKYN. Patients with major psychotic disorders, treated with neuroleptics, should be treated with dopamine agonists only if the potential benefits outweigh the risks. 7.5 Drugs Prolonging the QT/QTc Interval Caution should be exercised when prescribing APOKYN concomitantly with drugs that prolong the QT/QTc interval [see Warnings and Precautions (5.11) ] .

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action APOKYN is a non-ergoline dopamine agonist with high in vitro binding affinity for the dopamine D 4 receptor, and moderate affinity for the dopamine D 2 , D 3 , and D 5 , and adrenergic α 1 D, α 2 B, α 2 C receptors. The precise mechanism of action of APOKYN as a treatment for Parkinson's disease is unknown, although it is believed to be due to stimulation of post-synaptic dopamine D 2 -type receptors within the caudate-putamen in the brain. 12.2 Pharmacodynamics Prolongation of the QTc Interval In a thorough QT study at exposures similar to those achieved with the recommended dosing, apomorphine resulted in a prolongation of QTcF of 10 msec (90% upper confidence interval of 16 msec). The thorough QT study also identified a significant exposure-response relationship between apomorphine concentration and QTcF. Decreases in Blood Pressure Dose-dependent mean decreases in systolic blood pressure ranged from 5 mm Hg to 16 mm Hg after administration of APOKYN 2 mg and 10 mg, respectively. Dose-dependent mean decreases in diastolic blood pressure ranged from 3 mm Hg to 8 mm Hg after administration of APOKYN 2 mg and 10 mg, respectively. These changes were observed 20 minutes after dosing, and were maximal between 20 and 40 minutes after dosing. Lesser, but still noteworthy blood pressure decreases persisted up to at least 90 minutes after dosing. Effects on blood pressure are additive when APOKYN is coadministered with nitroglycerin or alcohol [see Drug Interactions (7.3 , 7.4) ]. 12.3 Pharmacokinetics Absorption Apomorphine hydrochloride is a lipophilic compound that is rapidly absorbed (time to peak concentration ranges from 10 minutes to 60 minutes) following subcutaneous administration into the abdominal wall. After subcutaneous administration, apomorphine appears to have bioavailability equal to that of an intravenous administration. Apomorphine exhibits linear pharmacokinetics over a dose range of 2 mg to 8 mg following a single subcutaneous injection of APOKYN into the abdominal wall in patients with idiopathic Parkinson's disease. Distribution The plasma-to-whole blood apomorphine concentration ratio is equal to one. Mean (range) apparent volume of distribution was 218 L (123 L to 404 L). Maximum concentrations in cerebrospinal fluid (CSF) are less than 10% of maximum plasma concentrations and occur 10 minutes to 20 minutes later. Metabolism and Elimination The mean apparent clearance (range) is 223 L/hr (125 L/hr to 401 L/hr) and the mean terminal elimination half-life is about 40 minutes (range about 30 minutes to 60 minutes). The route of metabolism in humans is not known. Potential routes of metabolism in humans include sulfation, N-demethylation, glucuronidation and oxidation. In vitro , apomorphine undergoes rapid autooxidation. Specific Populations The clearance of apomorphine does not appear to be influenced by age, gender, weight, duration of Parkinson's disease, levodopa dose, or duration of therapy. Renal Impairment In a study comparing renally-impaired subjects (moderately impaired as determined by estimated creatinine clearance) to healthy matched volunteers, the AUC 0 -∞ and C max values were increased by approximately 16% and 50%, respectively, following a single subcutaneous administration of APOKYN into the abdominal wall. The mean time to peak concentrations and the mean terminal half-life of apomorphine were unaffected by the renal status of the individual. Studies in subjects with severe renal impairment have not been conducted. The starting dose for patients with mild or moderate renal impairment should be reduced [see Dosage and Administration (2.4) and Use in Specific Populations (8.6) ] . Hepatic Impairment In a study comparing subjects with hepatic impairment (moderately impaired as determined by the Child-Pugh classification method) to healthy matched volunteers, the AUC 0 -∞ and C max values were increased by approximately 10% and 25%, respectively, following a single subcutaneous administration of APOKYN into the abdominal wall. Studies in subjects with severe hepatic impairment have not been conducted [see Dosage and Administration (2.5) and Use in Specific Populations (8.7) ] . Drug Interaction Studies Carbidopa/levodopa Levodopa pharmacokinetics were unchanged when subcutaneous APOKYN and levodopa were co-administrated in patients. However, motor response differences were significant. The threshold levodopa concentration necessary for an improved motor response was reduced significantly, leading to an increased duration of effect without a change in the maximal response to levodopa therapy. Ethanol and Nitroglycerin Co-administration of low dose ethanol (0.3 g/kg) or nitroglycerin (0.4 mg) with APOKYN in healthy subjects did not have a significant impact on the pharmacokinetics of apomorphine, but high dose ethanol (0.6 g/kg), equivalent to approximately 3 standardized alcohol-containing beverages, increased the C max of apomorphine by about 63%. However, the hypotensive effect of APOKYN was increased by the concomitant use of alcohol or of sublingual nitroglycerin [see Warnings and Precautions (5.4) and Drug Interactions (7.2 , 7.3) ]. Other Drugs Eliminated Via Hepatic Metabolism Based upon an in vitro study, cytochrome P450 enzymes play a minor role in the metabolism of apomorphine. In vitro studies have also demonstrated that drug interactions are unlikely due to apomorphine acting as a substrate, an inhibitor, or an inducer of cytochrome P450 enzymes. COMT Interactions A pharmacokinetic interaction of APOKYN with catechol-O-methyl transferase (COMT) inhibitors or drugs metabolized by this route is unlikely since apomorphine appears not to be metabolized by COMT.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Lifetime carcinogenicity studies of apomorphine were conducted in male (0.1, 0.3, or 0.8 mg/kg/day) and female (0.3, 0.8, or 2 mg/kg/day) rats. Apomorphine was administered by subcutaneous injection for 22 months or 23 months, respectively. In males, there was an increase in Leydig cell tumors at the highest dose tested, which is less than the MRHD (20 mg) on a mg/m 2 basis. This finding is of questionable significance because the endocrine mechanisms believed to be involved in the production of Leydig cell tumors in rats are not relevant to humans. No drug-related tumors were observed in females; the highest dose tested is similar to the MRHD on a mg/m 2 basis. In a 26-week carcinogenicity study in P53-knockout transgenic mice, there was no evidence of carcinogenic potential when apomorphine was administered by subcutaneous injection at doses up to 20 mg/kg/day (male) or 40 mg/kg/day (female). Mutagenesis Apomorphine was mutagenic in the in vitro bacterial reverse mutation (Ames) and the in vitro mouse lymphoma tk assays. Apomorphine was clastogenic in the in vitro chromosomal aberration assay in human lymphocytes and in the in vitro mouse lymphoma tk assay. Apomorphine was negative in the in vivo micronucleus assay in mice. Impairment of Fertility Apomorphine was administered subcutaneously at doses up to 3 mg/kg/day (approximately 1.5 times the MRHD on a mg/m 2 basis) to male and female rats prior to and throughout the mating period and continuing in females through gestation day 6. There was no evidence of adverse effects on fertility or on early fetal viability. A significant decrease in testis weight was observed in a 39-week study in cynomolgus monkey at all subcutaneous doses tested (0.3, 1, or 1.5 mg/kg/day); the lowest dose tested is less than the MRHD on a mg/m 2 basis. In a published fertility study, apomorphine was administered to male rats at subcutaneous doses of 0.2, 0.8, or 2 mg/kg prior to and throughout the mating period. Fertility was reduced at the highest dose tested.

13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Lifetime carcinogenicity studies of apomorphine were conducted in male (0.1, 0.3, or 0.8 mg/kg/day) and female (0.3, 0.8, or 2 mg/kg/day) rats. Apomorphine was administered by subcutaneous injection for 22 months or 23 months, respectively. In males, there was an increase in Leydig cell tumors at the highest dose tested, which is less than the MRHD (20 mg) on a mg/m 2 basis. This finding is of questionable significance because the endocrine mechanisms believed to be involved in the production of Leydig cell tumors in rats are not relevant to humans. No drug-related tumors were observed in females; the highest dose tested is similar to the MRHD on a mg/m 2 basis. In a 26-week carcinogenicity study in P53-knockout transgenic mice, there was no evidence of carcinogenic potential when apomorphine was administered by subcutaneous injection at doses up to 20 mg/kg/day (male) or 40 mg/kg/day (female). Mutagenesis Apomorphine was mutagenic in the in vitro bacterial reverse mutation (Ames) and the in vitro mouse lymphoma tk assays. Apomorphine was clastogenic in the in vitro chromosomal aberration assay in human lymphocytes and in the in vitro mouse lymphoma tk assay. Apomorphine was negative in the in vivo micronucleus assay in mice. Impairment of Fertility Apomorphine was administered subcutaneously at doses up to 3 mg/kg/day (approximately 1.5 times the MRHD on a mg/m 2 basis) to male and female rats prior to and throughout the mating period and continuing in females through gestation day 6. There was no evidence of adverse effects on fertility or on early fetal viability. A significant decrease in testis weight was observed in a 39-week study in cynomolgus monkey at all subcutaneous doses tested (0.3, 1, or 1.5 mg/kg/day); the lowest dose tested is less than the MRHD on a mg/m 2 basis. In a published fertility study, apomorphine was administered to male rats at subcutaneous doses of 0.2, 0.8, or 2 mg/kg prior to and throughout the mating period. Fertility was reduced at the highest dose tested.

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use) Administration with the APOKYN Pen Instruct patients and caregivers that the APOKYN Pen is dosed in milliliters, not milligrams. Inform patients and caregivers that it is possible to dial in their usual dose of APOKYN even though the cartridge may contain less than that amount of drug. In this case, they will receive only a partial dose with the injection, and the amount left to inject will appear in the dosing window. To complete the correct dose, patients/caregivers will need to "re-arm" the device and dial in the correct amount of the remaining dose. Patients and caregivers should be alerted to the fact that there may be insufficient drug left in the cartridge to deliver a complete dose (for example, patients and caregivers should be urged to keep records of how many doses they have delivered for each cartridge, so that they can replace any cartridge that has an inadequate amount of drug remaining). Instruct patients to rotate the injection site and to observe proper aseptic technique. Advise patients that APOKYN is intended only for subcutaneous injection and must not be given intravenously because of the risk of serious complications such as thrombus formation and pulmonary embolism due to crystallization [see Warnings and Precautions (5.1) ]. Hypersensitivity / Allergic Reactions Advise patients that hypersensitivity/allergic reaction characterized by urticaria, rash, pruritus, and/or various manifestations of angioedema may occur because of APOKYN or any of its excipients including a sulfite (i.e., sodium metabisulfite). Inform patients with a sulfite sensitivity that they may experience various allergic-type reactions, including anaphylactic symptoms and life-threatening asthmatic attacks [see Warnings and Precautions (5.13) ]. Advise patients who experience any hypersensitivity/allergic reaction to APOKYN that they should not take APOKYN again [see Contraindications (4) ]. Nausea and Vomiting Advise patients they may experience nausea and/or vomiting, which may be severe, and that treatment with oral trimethobenzamide 300 mg 3 times per day for 3 days prior to starting APOKYN injections has been used to help minimize these symptoms. Alternatively, starting APOKYN at a lower dose and titrating based on individual tolerance and treatment effect may be attempted. Advise patients that APOKYN taken with trimethobenzamide may increase the risks for somnolence, dizziness, and falls, and to consult their healthcare provider before discontinuing trimethobenzamide [see Warnings and Precautions (5.2) ] . Falling Asleep Suddenly and Sedation / Sleepiness Alert patients to the potential sedating effects of APOKYN, including somnolence and falling asleep while engaged in activities of daily living. Instruct patients not to drive a car or engage in other potentially dangerous activities until they have gained sufficient experience with APOKYN to gauge whether or not it affects their mental and/or motor performance adversely. Advise patients that if increased somnolence or episodes of falling asleep during activities of daily living (e.g., watching television, passenger in a car, etc.) occur, they should not drive or participate in potentially dangerous activities until they have contacted their physician. Because of possible additive effects of alcohol use, advise patients to limit their alcohol intake [see Warnings and Precautions (5.3) ]. Hypotension / Orthostatic Hypotension Advise patients that they may develop postural (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 months of treatment). Instruct patients to rise slowly after sitting or lying down after taking APOKYN. Inform patients that alcohol and nitroglycerin (and possibly other vasodilators and antihypertensive medications) may potentiate the hypotensive effect of APOKYN [see Warnings and Precautions (5.4) ]. Instruct patients ideally to lie down before taking sublingual nitroglycerin and to remain supine and avoid standing for at least 45 minutes after nitroglycerin. Instruct patients taking APOKYN to avoid alcohol while using APOKYN and of the increased hypotensive effects of APOKYN taken with nitroglycerin or by taking APOKYN after alcohol ingestion. Falls Alert patients that they may have increased risk for falling when using APOKYN [see Warnings and Precautions (5.5) ] . Hallucinations and/or Psychotic-Like Behavior Inform patients that hallucinations or other manifestations of psychotic-like behavior can occur. Tell patients if they have a major psychotic disorder, ordinarily they should not use APOKYN 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 APOKYN [see Warnings and Precautions (5.6) ] . Dyskinesia Inform patients that APOKYN may cause and/or exacerbate pre-existing dyskinesias [see Warnings and Precautions (5.7) ]. Hemolytic Anemia Inform patients and caregivers that hemolytic anemia may occur and to contact their healthcare provider if they develop any signs or symptoms [see Warnings and Precautions (5.8) ] . Impulse Control / Compulsive Behaviors Patients and their caregivers should be alerted to the possibility that they may experience intense urges to spend money uncontrollably, intense urges to gamble, increased sexual urges, binge eating and/or other intense urges and the inability to control these urges while taking APOKYN [see Warnings and Precautions (5.9) ] . Coronary Events Inform patients that APOKYN may cause coronary events including angina and myocardial infarction and these outcomes could possibly be related to significant hypotension/orthostatic hypotension [see Warnings and Precautions (5.10) ]. QTc Prolongation and Potential for Proarrhythymic Effects Alert patients that APOKYN may cause QTc prolongation and might produce proarrhythmic effects that could cause torsades de pointes and sudden death. Palpitations and syncope may signal the occurrence of an episode of torsades de pointes [see Warnings and Precautions (5.11) ]. Withdrawal-Emergent Hyperpyrexia and Confusion Advise patients to contact their healthcare provider if they wish to discontinue APOKYN or decrease the dose of APOKYN [see Warnings and Precautions (5.12) ]. Priapism Advise patients that APOKYN may cause prolonged painful erections and that if this occurs they should seek medical attention immediately [see Warnings and Precautions (5.15) ]. Injection Site Reactions Inform patients that injections of APOKYN may result in injection site reactions including bruising, granuloma, and pruritus [see Adverse Reactions (6.1) ].

APOKYN ® (apomorphine hydrochloride injection) APOKYN Pen APOKYN ® (apomorphine hydrochloride injection) is for under the skin (subcutaneous) injection only. Do not inject APOKYN into a vein. Do not use the APOKYN ® Pen unless you and your care partner have been taught the right way to use it and both of you understand all of the instructions. The APOKYN Pen is for use only with 3 mL APOKYN ® (apomorphine hydrochloride injection) Cartridges. The APOKYN Pen is only for use by 1 patient and should not be shared. Gray Pen Cap Gray Pen Body Pen Needle Unit Cartridge a. Clip Teal Cartridge Holder b. Black Rod c. White Dose Window d. White Dose Knob e. Teal Injection Button f. Outer Needle Shield g. Pink Inner Needle Shield h. Pen Needle i. Pink Paper Tab j. Rubber Septum k. Metal Cap l. Cartridge Plunger Read First: Important Safety Information The APOKYN Pen is a medicine delivery device. It is very important that you or your care partner read this Instructions for Use and follow the instructions for using the APOKYN Pen correctly to receive the correct APOKYN dose. Always perform a flow check (prime) before every injection and after loading a new cartridge. The liquid in the APOKYN Cartridge can cause irritation if it gets on your skin or in your eyes. Flush your eyes with cold water and wash the liquid off your skin right away if this happens. The BD pen needle unit is sterile. Avoid contaminating the needle after opening. Do not place it on a surface or touch other items with the needle. Do not dial the dose or try to correct a dialing error with the pen needle in the skin. You could receive the wrong dose. Be careful when removing the needle. Accidental needle sticks can transmit serious infections. Never store or carry the APOKYN Pen with a pen needle attached. Never recap pen with needle attached. Storing or carrying the APOKYN Pen with a pen needle attached may let: Air enter the cartridge Medicine leak out This can affect your APOKYN dose. The APOKYN Pen should only be used with pen needles (29G × 1/2"). These needles are available through your specialty pharmacy provider or your local pharmacy. You must use a new, sterile BD pen needle with each injection. Magnification: 50× How to Use the APOKYN Pen Preparing the APOKYN Pen for Cartridge Loading Step 1. Remove the gray pen cap by pulling it straight off. Step 2. Unscrew the teal cartridge holder from the gray pen body by turning it clockwise. Loading a Cartridge Step 3. Only use APOKYN that is clear and colorless. Do not use an APOKYN Cartridge that contains medicine that is cloudy, green, or contains particles. Call your specialty pharmacy provider for replacement cartridges. Insert the APOKYN Cartridge, metal cap first, into the teal cartridge holder. Step 4. Lower the gray pen body onto the teal cartridge holder so that the black rod presses against the cartridge plunger. Screw the teal cartridge holder onto the gray pen body. Tighten the pieces by turning the teal cartridge holder clockwise until no gap remains and 1 of the white arrows line up with the white marker on the gray pen body. Step 5. If you already have a cartridge in the pen and have used the pen, you should check the cartridge through the window in the teal cartridge holder to make sure there is enough APOKYN solution in the cartridge to provide your next dose. If the gray cartridge plunger has reached the red line on the cartridge, remove the cartridge and insert a new cartridge into the pen before attaching the pen needle and preparing the dose. Attaching the Pen Needle Step 6. Remove the pink paper tab from the back of a new pen needle. Use a new needle for each injection. Never reuse needles. Step 7. Holding the APOKYN Pen by the teal cartridge holder, push the pen needle unit onto the pen. Screw the threaded hub of the pen needle onto the teal cartridge holder counter-clockwise. When the needle unit is attached, remove the outer shield that protects the needle with a gentle pull. Save the outer shield. You will use it to remove the needle from the pen after the injection is finished. Do not remove the inner needle shield at this time. The needle is sterile and must stay clean. After opening, do not place the needle on a surface or let it touch anything. Preparing (Priming) the APOKYN Pen for Use IMPORTANT – Prior to each injection, it is important that the APOKYN Pen be properly primed. For a new APOKYN Cartridge (1 that has not been used before), repeat the priming procedure described on the next page (Steps 8-9) 3 or 4 times to make sure all the air has been removed from the needle and cartridge. For an APOKYN Cartridge you have used before (1 that has been previously primed), repeat the priming procedure described on the next page (Steps 8-9) 1 time to make sure all the air has been removed from the needle and cartridge. Step 8. You must prepare (prime) the APOKYN Pen for use before injecting the medicine. To prime the APOKYN Pen, set the dose by turning the dose knob to 0.1 mL. This is important so you can get rid of any air bubbles in the cartridge. Step 9. Remove the inner needle shield. Remember, do not let the needle touch anything. With the needle pointing up, firmly push the injection button in as far as it will go and hold for at least 5 seconds. A small stream of medicine must come out of the end of the needle. If it does not, reset the dose by repeating Step 8. Repeat these steps (Steps 8-9) until a small stream of medicine comes out the end of the needle. When medicine comes out of the end of the needle, the APOKYN Pen is primed for injection and ready to use. APOKYN medicine can cause staining to fabric and other surfaces it touches. Be careful where you prime the APOKYN Pen. Setting the Dose Step 10. To set the dose, turn the white dose knob until the correct dose (number of mLs) is shown in the window. The dose will appear as a red number between two black lines that will line up next to the letters "mL" on the pen body. Make sure the correct number (dose) appears in the window. Step 11. Dose Correction. If you turn the dose knob past your dose, do not dial backwards. If you dial backwards, APOKYN will be pushed through the needle and you will lose medicine. Continue to turn the dial until it is fully turned. Press the injection button fully. This will reset the dial to zero without pushing medicine out of the needle. Repeat Step 10 to redial your dose. Giving the Injection Step 12. APOKYN is only for injection under the skin (subcutaneous injection). Choose an injection site on your stomach area, upper arm or upper leg. Change the site with each injection. Do not inject APOKYN into skin that is red or sore. Clean the site with an alcohol swab and allow to air dry. Pinch about an inch of skin and fat tissue of your injection site between your thumb and forefinger. With the other hand, insert the needle all the way into the pinched skin. Step 13. Fully push the teal injection button on the APOKYN Pen. A clicking sound will be heard while the dose is injected. Push the injection button firmly for 5 seconds. Remove the needle from your skin. If medicine keeps dripping from the needle, keep the needle in the skin longer the next time you inject APOKYN. IMPORTANT – If you set your dose and cannot depress the teal injection button, the cartridge is empty. Remove the pen needle and cartridge and prepare the pen as described in Steps 2-9 with a new cartridge. Set the dose and give the injection. If you set your dose and the injection button stops before you receive a complete dose, note the number in the window, remove the pen needle and cartridge, and prepare the pen as described in Steps 2-9 with a new cartridge. Set the dose to the number that last appeared in the window and administer the injection. This completes the dose. Before attempting to replace a cartridge, be sure that a needle unit is not attached to the APOKYN Pen. Removing the Pen Needle Step 14. Carefully replace the outer needle shield. Be careful to avoid a needle-stick. Place the outer needle shield in the notch located on the far left side of your carrying case. The opening of the needle shield should be pointing up. Carefully insert the needle (attached to the pen) into the opening of the shield. Without holding onto the shield, push down firmly. Step 15. Hold the pen by the teal cartridge holder and unscrew the pen needle from the cartridge holder. Recap the pen. Never recap the pen with a needle attached. Safely dispose of used pen needles in a "sharps" container. Your specialty pharmacy provider will provide you with a "sharps" container. Do not throw used needles in a trash can. Storage Information –Store APOKYN cartridges at room temperature, 68°F to 77°F (20°C to 25°C) Excursions permitted between 59 to 86°F (15 to 30°C) [See USP Controlled Room Temperature] Proper Disposal Put your used needles and syringes in an FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles and syringes in your household trash. If you do not have an FDA-cleared sharps disposal container, you may use a household container that is: made of a heavy-duty plastic able to be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out upright and stable during use leak-resistant properly labeled to warn of hazardous waste inside the container When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used needles and syringes. For more information about safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA's website at: http://www.fda.gov/safesharpsdisposal. Do not dispose of your used sharps disposal container in your household trash unless your community guidelines permit this. Do not recycle your used sharps disposal container. Care and Storage The APOKYN Pen can now be stored in its carrying case. Never store or carry the APOKYN Pen with a pen needle attached. You must store and care for your pen the right way: Avoid exposure to dust, moisture, and cold or hot temperatures. Never wash the pen in water or use strong disinfectants. Only a clean, damp cloth should be used for cleaning. Do not try to repair the pen if it is damaged or if you cannot solve a problem shown in the following "Troubleshooting" section. Do not use pen for more than 1 year after the first use or after the expiration date on the carton. For more information, call your specialty pharmacy provider or 1-877-7APOKYN (727-6596).

14 CLINICAL STUDIES The effectiveness of APOKYN in the acute symptomatic treatment of the recurring episodes of hypomobility, "off" episodes ("end-of-dose wearing off" and unpredictable "on/off" episodes), in patients with advanced Parkinson's disease was established in three randomized, controlled trials of APOKYN given subcutaneously (Studies 1, 2, and 3). At baseline in these trials, the mean duration of Parkinson's disease was approximately 11 years. Whereas all patients were using concomitant L-dopa at baseline, 86% of patients were using a concomitant oral dopaminergic agonist, 31% were using a concomitant catechol-ortho-methyl transferase (COMT) inhibitor, and 10% were using a concomitant monoamine B oxidase inhibitor. Study 1 was conducted in patients who did not have prior exposure to APOKYN (i.e., APOKYN naïve) and Studies 2 and 3 were conducted in patients with at least 3 months of APOKYN use immediately prior to study enrollment. Almost all patients without prior exposure to APOKYN began taking an antiemetic (trimethobenzamide) three days prior to starting APOKYN and 50% of patients were able to discontinue the concomitant antiemetic, on average 2 months after initiating APOKYN. The change from baseline in Part III (Motor Examination) of the Unified Parkinson's Disease Rating Scale (UPDRS) served as the primary outcome assessment measure in each study. Part III of the UPDRS contains 14 items designed to assess the severity of the cardinal motor findings (e.g., tremor, rigidity, bradykinesia, postural instability, etc.) in patients with Parkinson's disease. Study 1 Study 1 was a randomized, double-blind, placebo-controlled, parallel-group trial in 29 patients with advanced Parkinson's disease who had at least 2 hours of "off" time per day despite an optimized oral regimen for Parkinson's disease including levodopa and an oral dopaminergic agonist. Patients with atypical Parkinson's disease, psychosis, dementia, hypotension, or those taking dopamine antagonists were excluded from participation. In an office setting, hypomobility was allowed to occur by withholding the patients' Parkinson's disease medications overnight. The following morning, patients (in a hypomobile state) were started on study treatment in a 2:1 ratio (2 mg of APOKYN or placebo given subcutaneously). At least 2 hours after the first dose, patients were given additional doses of study medication until they achieved a "therapeutic response" (defined as a response similar to the patient's response to their usual dose of levodopa) or until 10 mg of APOKYN or placebo equivalent was given. At each injection re-dosing, the study drug dose was increased in 2 mg increments up to 4 mg, 6 mg, 8 mg, 10 mg of APOKYN) or placebo equivalent. Of the 20 patients randomized to APOKYN, 18 achieved a "therapeutic response" at about 20 minutes. The mean APOKYN dose was 5.4 mg (3 patients on 2 mg, 7 patients on 4 mg, 5 patients on 6 mg, 3 patients on 8 mg, and 2 patients on 10 mg). In contrast, of the 9 placebo-treated patients, none reached a "therapeutic response." The mean change from baseline for UPDRS Part III score for APOKYN group (highest dose) was statistically significant compared to that for the placebo group (Table 2). Table 2: Mean Change from Baseline in UPDRS Motor Score for Intent-to-Treat Population in Study 1 Treatment Baseline UPDRS Motor Score Mean Change from Baseline Difference from placebo Placebo 36.3 - 0.1 NA APOKYN 39.7 - 23.9 - 23.8 Study 2 Study 2 used a randomized, placebo-controlled crossover design of 17 patients with Parkinson's disease who had been using APOKYN for at least 3 months. Patients received their usual morning doses of Parkinson's disease medications and were followed until hypomobility occurred, at which time they received either a single dose of subcutaneous APOKYN (at their usual dose) and placebo on different days in random order. UPDRS Part III scores were evaluated over time. The mean dose of APOKYN was 4 mg (2 patients on 2 mg, 9 patients on 3 mg, 2 patients on 4 mg, and 1 patient each on 4.5 mg, 5 mg, 8 mg, and 10 mg). The mean change from baseline UPDRS Part III score for the APOKYN group was statistically significant compared to that for the placebo group (Table 3). Table 3: Mean Change from Baseline in UPDRS Motor Score for Intent-to-Treat Population in Study 2 Treatment Baseline UPDRS Motor Score Mean Change from Baseline Difference from placebo Placebo 40.1 - 3.0 NA APOKYN 41.3 - 20.0 - 17.0 Study 3 Study 3 used a randomized withdrawal design in 4 parallel groups from 62 patients (APOKYN-35; Placebo-27) with Parkinson's disease who had been using APOKYN for at least 3 months. Patients were randomized to one of the following 4 treatments dosed once by subcutaneous administration: APOKYN at the usual dose (mean dose 4.6 mg), placebo at a volume matching the usual APOKYN dose, APOKYN at the usual dose + 2 mg (0.2 mL) (mean dose 5.8 mg), or placebo at a volume matching the usual APOKYN dose + 0.2 mL. Patients received their usual morning doses of Parkinson's disease medications and were followed until hypomobility occurred, at which time they received the randomized treatment. APOKYN doses ranged between 2 mg – 10 mg. The mean change from baseline for the APOKYN group for UPDRS Part III scores at 20 minutes post dosing was statistically significant compared to that for the placebo group (Table 4). Figure 2 describes the mean change from baseline in UPDRS Motor Scores over time for pooled APOKYN and placebo administration. Table 4: Mean Change from Baseline in UPDRS Motor Score for Intent-to-Treat Population in Study 3 Treatment Baseline UPDRS Motor Score Mean Change from Baseline Difference from placebo Placebo (Pooled) 40.6 - 7.4 NA APOKYN (Pooled) 42.0 - 24.2 - 16.8 Figure 2: Mean Change from Baseline in UPDRS Motor Scores of Pooled APOKYN Groups and Placebo Group in Study 3 In Study 3, the mean changes from baseline for UPDRS Part III scores at 20 minutes post dosing for the APOKYN and higher dose APOKYN groups were 24 and 25, respectively. This result suggests that patients chronically treated at a dose of 4 mg might derive little additional benefit from a dose increment of 2 mg. There was also an increased incidence of adverse reactions in patients randomized to higher APOKYN dose. Figure 2

8.5 Geriatric Use In the APOKYN clinical development program, there were 239 patients less than age 65 treated with APOKYN and 311 patients who were age 65 or older. Confusion and hallucinations were reported more frequently with patients age 65 and older compared to patients with less than age 65. Serious adverse reactions (life-threatening events or events resulting in hospitalization and/or increased disability) were also more common in patients age 65 and older. Patients age 65 and older were more likely to fall (experiencing bone and joint injuries), have cardiovascular events, develop respiratory disorders, and have gastrointestinal events. Patients age 65 and above were also more likely to discontinue APOKYN treatment as a result of one or more adverse reactions.

8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established.

8.1 Pregnancy Risk Summary There are no adequate data on the developmental risk associated with use of APOKYN in pregnant women. In animal reproduction studies, apomorphine had adverse developmental effects in rats (increased neonatal deaths) and rabbits (increased incidence of malformation) when administered during pregnancy at clinically relevant doses. These doses were also associated with maternal toxicity [see 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 background risk of major birth defects and miscarriage for the indicated population is unknown. Data Animal Data No adverse developmental effects were observed when apomorphine (0.3, 1, or 3 mg/kg/day) was administered by subcutaneous injection to pregnant rats throughout organogenesis; the highest dose tested is 1.5 times the maximum recommended human dose (MRHD) of 20 mg/day on a mg/m 2 basis. Administration of apomorphine (0.3, 1, or 3 mg/kg/day) by subcutaneous injection to pregnant rabbits throughout organogenesis resulted in an increased incidence of malformations of the heart and/or great vessels at the mid and high doses; maternal toxicity was observed at the highest dose tested. The no-effect dose for adverse developmental effects is less than the MRHD on a mg/m 2 basis. Apomorphine (0.3, 1, or 3 mg/kg/day), administered by subcutaneous injection to females throughout gestation and lactation, resulted in increased offspring mortality at the highest dose tested, which was associated with maternal toxicity. There were no effects on developmental parameters or reproductive performance in surviving offspring. The no-effect dose for developmental toxicity (1 mg/kg/day) is less than the MRHD on a mg/m 2 basis.

Administration of apomorphine (0.3, 1, or 3 mg/kg/day) by subcutaneous injection to pregnant rabbits throughout organogenesis resulted in an increased incidence of malformations of the heart and/or great vessels at the mid and high doses; maternal toxicity was observed at the highest dose tested. The no-effect dose for adverse developmental effects is less than the MRHD on a mg/m 2 basis. Apomorphine (0.3, 1, or 3 mg/kg/day), administered by subcutaneous injection to females throughout gestation and lactation, resulted in increased offspring mortality at the highest dose tested, which was associated with maternal toxicity. There were no effects on developmental parameters or reproductive performance in surviving offspring. The no-effect dose for developmental toxicity (1 mg/kg/day) is less than the MRHD on a mg/m 2 basis. 8.2 Lactation Risk Summary There are no data on the presence of apomorphine in human milk, the effects of apomorphine on the breastfed infant, or the effects of apomorphine on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for APOKYN and any potential adverse effects on the breastfed infant from APOKYN or from the underlying maternal condition. 8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established. 8.5 Geriatric Use In the APOKYN clinical development program, there were 239 patients less than age 65 treated with APOKYN and 311 patients who were age 65 or older. Confusion and hallucinations were reported more frequently with patients age 65 and older compared to patients with less than age 65. Serious adverse reactions (life-threatening events or events resulting in hospitalization and/or increased disability) were also more common in patients age 65 and older. Patients age 65 and older were more likely to fall (experiencing bone and joint injuries), have cardiovascular events, develop respiratory disorders, and have gastrointestinal events. Patients age 65 and above were also more likely to discontinue APOKYN treatment as a result of one or more adverse reactions. 8.6 Renal Impairment The starting APOKYN dose should be reduced in patients with mild or moderate renal impairment because the concentration and exposure (C max and AUC) are increased in these patients. Studies in subjects with severe renal impairment have not been conducted [see Dosage and Administration (2.4) and Clinical Pharmacology (12.3) ] . 8.7 Hepatic Impairment Caution should be exercised when administrating APOKYN to patients with mild and moderate hepatic impairment because of the increased C max and AUC in these patients. Closely monitor patients with mild and moderate hepatic impairment. Studies of subjects with severe hepatic impairment have not been conducted [see Clinical Pharmacology (12.3) ] .
