6 ADVERSE REACTIONS The following adverse reactions are discussed in more detail in other sections of the labeling: Use in Elderly Patients with Dementia-Related Psychosis [see Boxed Warning and Warnings and Precautions ( 5.1 and 5.2 )] Neuroleptic Malignant Syndrome [see Warnings and Precautions ( 5.3 )] Tardive Dyskinesia [see Warnings and Precautions ( 5.4 )] Metabolic Changes [see Warnings and Precautions ( 5.5 )] Hypersensitivity Reactions [see Contraindications, Warnings and Precautions ( 5.6 )] Orthostatic Hypotension, Syncope, and other Hemodynamic Effects [see Warnings and Precautions ( 5.7 )] Falls [see Warnings and Precautions ( 5.8 )] Leukopenia, Neutropenia, and Agranulocytosis [see Warnings and Precautions ( 5.9 )] QT Interval Prolongation [see Warnings and Precautions ( 5.10 )] Hyperprolactinemia [see Warnings and Precautions ( 5.11 )] Seizures [see Warnings and Precautions ( 5.12 )] Potential for Cognitive and Motor Impairment [see Warnings and Precautions ( 5.13 )] Body Temperature Regulation [see Warnings and Precautions ( 5.14 )] Dysphagia [see Warnings and Precautions ( 5.15 )] The most common adverse reactions (≥5% and at least twice the rate of placebo) reported with acute treatment in adults with schizophrenia were akathisia, oral hypoesthesia, and somnolence. The safety profile of asenapine in the maintenance treatment of schizophrenia in adults was similar to that seen with acute treatment. The most common adverse reactions (≥5% and at least twice the rate of placebo) reported with acute monotherapy treatment of manic or mixed episodes associated with bipolar I disorder in adults were somnolence, oral hypoesthesia dizziness, extrapyramidal symptoms (excluding akathisia) and akathisia; and during the adjunctive therapy trial in bipolar I disorder in adults were somnolence and oral hypoesthesia. The rates were lower at the 5 mg twice daily dose than the 10mg twice daily dose for all of these most common adverse reactions. The safety profile of asenapine in the maintenance treatment of manic or mixed episodes associated with bipolar I disorder in adults was similar to that seen with acute treatment. The adult information below is derived from a clinical trial database for asenapine consisting of over 5355 patients and/or healthy subjects exposed to one or more sublingual doses of asenapine. A total of 1427 asenapine-treated patients were treated for at least 24 weeks and 785 asenapine-treated patients had at least 52 weeks of exposure at therapeutic doses. In a 3-week monotherapy trial, the most common adverse reactions (≥5% and at least twice the rate of placebo) reported in pediatric patients with bipolar I disorder treated with asenapine were somnolence, dizziness, dysgeusia, oral hypoesthesia, nausea, increased appetite, fatigue, and increased weight. No new major safety findings were reported from a 50-week, open-label, uncontrolled safety trial. A total of 651 pediatric patients were treated with asenapine. Of these patients, 352 pediatric patients were treated with asenapine for at least 180 days and 58 pediatric patients treated with asenapine had at least 1 year of exposure. The safety of asenapine was evaluated in 403 pediatric patients with bipolar I disorder who participated in a 3-week, placebo-controlled, double-blind trial, of whom 302 patients received asenapine at fixed doses ranging from 2.5 mg to 10 mg twice daily. The stated frequencies of adverse reactions represent the proportion of individuals who experienced a treatment-emergent adverse event of the type listed. A reaction was considered treatment emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. The most commonly observed adverse reactions (incidence ≥5% and at least twice that for placebo) were ( 6.1 ): Schizophrenia Adults : akathisia, oral hypoesthesia, somnolence. Bipolar I Disorder Adults (Monotherapy): somnolence, oral hypoesthesia, dizziness, extrapyramidal symptoms (excluding akathisia) and akathisia. Bipolar I Disorder Pediatric Patients (Monotherapy): somnolence, dizziness, dysgeusia, oral paresthesia, nausea, increased appetite, fatigue, increased weight. Bipolar I Disorder Adults (Adjunctive): somnolence, oral hypoesthesia.

Adult Patients with Schizophrenia: The following findings are based on the short-term placebo-controlled pre-marketing trials for schizophrenia (a pool of three 6-week fixed-dose trials and one 6-week flexible-dose trial) in which sublingual asenapine was administered in doses ranging from 5 to 10 mg twice daily. Adverse Reactions Associated with Discontinuation of Treatment: A total of 9% of asenapine-treated patients and 10% of placebo-treated patients discontinued due to adverse reactions. There were no drug-related adverse reactions associated with discontinuation in patients treated with asenapine at the rate of at least 1% and at least twice the placebo rate. Adverse Reactions Occurring at an Incidence of 2% or More in A senapine -Treated Patients with Schizophrenia : Adverse reactions associated with the use of asenapine (incidence of 2% or greater, rounded to the nearest percent, and asenapine incidence greater than placebo) that occurred during acute therapy (up to 6-weeks in patients with schizophrenia) are shown in Table 8 .

Dose-Related Adverse Reactions: In the short term schizophrenia trials the incidence of akathisia appeared to be dose-related (see Table 8). Monotherapy in Adult Patients with Bipolar Mania: The following findings are based on the short-term placebo-controlled trials for bipolar mania (a pool of two 3-week flexible-dose trials and one 3-week fixed-dose trial) in which sublingual asenapine was administered in doses of 5 mg or 10 mg twice daily. Adverse Reactions Associated with Discontinuation of Treatment: Approximately 10% (61/620) of asenapine-treated patients in short-term, placebo-controlled trials discontinued treatment due to an adverse reaction, compared with about 7% (22/329) on placebo. There were no adverse reactions associated with discontinuation in patients treated with asenapine at the rate of at least 1% and at least twice the placebo rate. Adverse Reactions Occurring at an Incidence of 2% or More Among A senapine -Treated (Monotherapy ) patients with Bipolar I Disorder : Adverse reactions associated with the use of asenapine (incidence of 2% or greater, rounded to the nearest percent, and asenapine incidence greater than placebo) that occurred during acute monotherapy (up to 3-weeks in patients with bipolar mania) are shown in Table 9 .

Monotherapy in Pediatric Patients with Bipolar Mania: The following findings are based on a 3-week, placebo-controlled trial for bipolar mania in which asenapine was administered at doses of 2.5 mg, 5 mg, or 10 mg twice daily. Adverse Reactions Leading to Discontinuation of Treatment: A total of 6.7% (7/104) of patients treated with asenapine 2.5 mg twice daily, 5.1% (5/99) of patients treated with asenapine 5 mg twice daily, and 5.1% (5/99) of patients treated with asenapine 10 mg twice daily discontinued treatment due to adverse reactions compared to 4% (4/101) on placebo. The most common adverse reactions that led to discontinuation in pediatric patients treated with asenapine (rates at least 2% in any asenapine arm and at least twice the placebo rate) were somnolence (3% in the 2.5 mg twice daily group, 1% in the 5mg twice daily group, and 2% in the 10 mg twice daily group), abdominal pain (2% in the 10 mg twice daily group), and nausea (2% in the 10 mg twice daily group). No placebo-treated patients dropped out for these events. Adverse Reactions Occurring with A senapine at an Incidence of 2% or More in A senapine -treated Bipolar I Patients: Adverse reactions associated with the use of asenapine (incidence of ≥2% in any asenapine dose group and greater than placebo) that occurred during acute therapy are shown in Table 10 .

Dose-Related Adverse Reactions: In the short term pediatric bipolar I trial the incidence of fatigue appeared to be dose-related (see Table 10 ). Adjunctive Therapy in Adult Patients with Bipolar Mania: The following findings are based on a 12 week placebo-controlled trial (with a 3 week efficacy endpoint) in adult patients with bipolar mania in which sublingual asenapine was administered in doses of 5 mg or 10 mg twice daily as adjunctive therapy with lithium or valproate. Adverse Reactions Associated with Discontinuation of Treatment: Approximately 16% (25/158) of asenapine-treated patients discontinued treatment due to an adverse reaction, compared with about 11% (18/166) on placebo. The most common adverse reactions associated with discontinuation in subjects treated with asenapine (rates at least 1% and at least twice the placebo rate) were depression (2.5%), suicidal ideation (2.5%), bipolar I disorder (1.9%), insomnia (1.9%) and depressive symptoms (1.3%). Adverse Reactions Occurring at an Incidence of 2% or More Among A senapine -Treated (Adjunctive) Bipolar I Patients: Adverse reactions associated with the use of asenapine (incidence of 2% or greater, rounded to the nearest percent, and asenapine incidence greater than placebo) that occurred during acute adjunctive therapy at 3 weeks, a time when most of the patients were still participating in the trial, are shown in Table 11 .

Dystonia: Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. While these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and at higher doses of first generation antipsychotic drugs. An elevated risk of acute dystonia is observed in males and younger age groups [see Dosage and Administration ( 2.3 ), Use in Specific Populations ( 8.4 ), and Clinical Pharmacology ( 12.3 )] . Extrapyramidal Symptoms: In the short-term, placebo-controlled schizophrenia and bipolar mania adult trials, data was objectively collected on the Simpson Angus Rating Scale for extrapyramidal symptoms (EPS), the Barnes Akathisia Scale (for akathisia) and the Assessments of Involuntary Movement Scales (for dyskinesias). The mean change from baseline for the all-asenapine 5 mg or 10 mg twice daily treated group was comparable to placebo in each of the rating scale scores. In the short-term, placebo-controlled schizophrenia adult trials, the incidence of reported EPS-related events, excluding events related to akathisia, for asenapine-treated patients was 10% versus 7% for placebo; and the incidence of akathisia-related events for asenapine-treated patients was 6% versus 3% for placebo. In short-term placebo-controlled bipolar mania adult trials, the incidence of EPS-related events, excluding events related to akathisia, for asenapine-treated patients was 8% versus 4% for placebo; and the incidence of akathisia-related events for asenapine-treated patients was 7% versus 3% for placebo. The incidence rates of all EPS events (including akathisia) were lower at the 5 mg twice daily dose (11% of N=122) than the 10 mg twice daily dose (25% of N=119) in a fixed-dose study. In a 3-week, placebo-controlled pediatric trial with bipolar I disorder, the incidences of EPS-related events, excluding events related to akathisia, were 4%, 3%, and 5% for patients treated with asenapine 2.5 mg, 5 mg, and 10 mg twice daily, respectively, as compared to 3% for placebo-treated patients. EPS-related events include: bradykinesia, dyskinesia, dystonia, oromandibular dystonia, muscle contractions involuntary, muscle twitching, musculoskeletal stiffness, parkinsonism, protrusion tongue, resting tremor, and tremor. For events of akathisia, incidences were 2%, 2%, and 1% for pediatric patients treated with asenapine 2.5 mg, 5 mg, and 10 mg twice daily, respectively, as compared to 0% for placebo-treated patients. Other Findings: Oral hypoesthesia and/or oral paresthesia may occur directly after administration of asenapine and usually resolves within 1 hour. Laboratory Test Abnormalities: Transaminases: Transient elevations in serum transaminases (primarily ALT) in the short-term schizophrenia and bipolar mania adult trials were more common in treated patients. In short-term, placebo-controlled schizophrenia adult trials, the mean increase in transaminase levels for asenapine-treated patients was 1.6 units/L compared to a decrease of 0.4 units/L for placebo-treated patients. The proportion of patients with transaminase elevations ≥3 times ULN (at Endpoint) was 0.9% for asenapine-treated patients versus 1.3% for placebo-treated patients. In short-term, placebo-controlled bipolar mania adult trials, the mean increase in transaminase levels for asenapine-treated patients was 6.1 units/L compared to a decrease of 3.9 units/L in placebo-treated patients. The proportion of patients with transaminase elevations ≥3 times upper limit of normal (ULN) (at Endpoint) was 2.1% for asenapine-treated patients versus 0.7% for placebo-treated patients. The incidence rate of transaminase elevations ≥3 times ULN is 3% of N=95 for 10 mg twice daily dose, and 0% of N=108 for the 5 mg twice daily dose and 0% of N=115 for placebo in a fixed-dose study. In a 52-week, double-blind, comparator-controlled trial that included primarily adult patients with schizophrenia, the mean increase from baseline of ALT was 1.7 units/L. In a 3-week, placebo-controlled pediatric trial with bipolar I disorder, transient elevations in serum transaminases (primarily ALT) were more common in treated patients. The proportion of pediatric patients with ALT elevations ≥3 times upper limit of normal (ULN) was 2.4% for patients treated with asenapine 10 mg twice daily versus none for the other asenapine dose groups and placebo-treated patients. Prolactin: In short-term, placebo-controlled adult schizophrenia trials, the mean decreases in prolactin levels were 6.5 ng/mL for asenapine-treated patients compared to 10.7 ng/mL for placebo-treated patients. The proportion of patients with prolactin elevations ≥4 times ULN (at Endpoint) were 2.6% for asenapine-treated patients versus 0.6% for placebo-treated patients. In short-term, placebo-controlled bipolar mania adult trials, the mean increase in prolactin levels was 6.7ng/mL for asenapine-treated patients compared to a decrease of 1.0 ng/mL for placebo-treated patients. The proportion of patients with prolactin elevations ≥4 times ULN (at Endpoint) were 2.0% for asenapine-treated patients versus 0.8% for placebo-treated patients. In a long-term (52-week), double-blind, comparator-controlled adult trial that included primarily patients with schizophrenia, the mean decrease in prolactin from baseline for asenapine-treated patients was 26.9 ng/mL. In a 3-week, placebo-controlled pediatric trial with bipolar I disorder, the mean increases (at Endpoint) in prolactin levels were 3.2 ng/mL for patients treated with asenapine 2.5 mg twice daily, 2.1 ng/mL for patients treated with asenapine 5 mg twice daily, and 6.4 ng/mL for patients treated with asenapine 10 mg twice daily compared to an increase of 2.5 ng/mL for placebo-treated patients. There were no reports of prolactin elevations ≥4 times ULN (at Endpoint) for patients treated with asenapine or placebo. Galactorrhea or dysmenorrhea were reported in 0% of patients treated with asenapine 2.5 mg twice daily, 2% of patients treated with asenapine 5 mg twice daily, and 1% of patients treated with asenapine 10 mg twice daily compared to 1% of placebo-treated patients. There were no reports of gynecomastia in this trial. Creatine Kinase (CK): The proportion of adult patients with CK elevations >3 times ULN at any time were 6.4% and 11.1% for patients treated with asenapine 5 mg twice daily and 10 mg twice daily, respectively, as compared to 6.7% for placebo-treated patients in pre-marketing short-term, fixed-dose trials in schizophrenia and bipolar mania. The clinical relevance of this finding is unknown. The proportion of patients with CK elevations ≥3 times ULN during a 3-week trial in pediatric bipolar I disorder at any time were 1%, 0%, and 1% for patients treated with asenapine 2.5 mg, 5 mg, and 10 mg twice daily, respectively, versus 3% for placebo-treated patients. O ther Adverse Reactions Observed During the Premarketing Evaluation of Asenapine : Following is a list of MedDRA terms that reflect adverse reactions reported by patients treated with sublingual asenapine at multiple doses of ≥5 mg twice daily during any phase of a trial within the database of adult patients. The reactions listed are those that could be of clinical importance, as well as reactions that are plausibly drug-related on pharmacologic or other grounds. Reactions already listed for either adults or pediatric patients in other parts of Adverse Reactions ( 6 ) , or those considered in Contraindications ( 4 ), Warnings and Precautions ( 5 ) or Overdosage ( 10 ) are not included. Reactions are further categorized by MedDRA system organ class and listed in order of decreasing frequency according to the following definitions: those occurring in at least 1/100 patients (frequent) (only those not already listed in the tabulated results from placebo-controlled trials appear in this listing); those occurring in 1/100 to 1/1,000 patients (infrequent); and those occurring in fewer than 1/1,000 patients (rare). Blood and lymphatic disorders: infrequent : anemia; rare : thrombocytopenia Cardiac disorders: infrequent : temporary bundle branch block Eye disorders: infrequent : accommodation disorder Gastrointestinal disorders: infrequent : swollen tongue General disorders: rare : idiosyncratic drug reaction Investigations: infrequent : hyponatremia Nervous system disorders: infrequent : dysarthria Following is a list of MedDRA terms not already listed either for adults or pediatric patients in other parts of Adverse Reactions ( 6 ) , or those considered in Contraindications ( 4 ), Warnings and Precautions ( 5 ) or Overdosage ( 10 ) that reflect adverse reactions reported by pediatric patients (Ages 10 to 17 years) treated with sublingual asenapine at doses of 2.5 mg, 5 mg, or 10 mg twice daily during any phase of a trial within the database of pediatric patients. Eye disorders: infrequent: diplopia, vision blurred Gastrointestinal disorders: infrequent: gastroesophageal reflux disease Injury, Poisoning, and Procedural Complication s : infrequent : fall Skin and subcutaneous tissue disorders: infrequent : photosensitivity reaction Renal and urinary disorders: infrequent: enuresis 6. 2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of asenapine. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to establish a causal relationship to drug exposure. In many cases, the occurrence of these adverse reactions led to discontinuation of therapy. • Application site reactions, primarily in the sublingual area, have been reported. These application site reactions included oral ulcers, blisters, peeling/sloughing, and inflammation. • Choking has been reported by patients, some of whom may have also experienced oropharyngeal muscular dysfunction or hypoesthesia.

To ensure optimal absorption, patients should be instructed to place the tablet under the tongue and allow it to dissolve completely. The tablet will dissolve in saliva within seconds. Asenapine sublingual tablets should not be split, crushed, chewed, or swallowed [s ee Clinical Pharmacology ( 12.3 )] . Patients should be instructed to not eat or drink for 10 minutes after administration [ see Clinical Pharmacology ( 12.3 ) ] . 2.2 Schizophrenia The recommended dose of asenapine is 5 mg given twice daily. In short-term controlled trials, there was no suggestion of added benefit with a 10 mg twice daily dose, but there was a clear increase in certain adverse reactions. If tolerated, daily dosage can be increased to 10 mg twice daily after one week. The safety of doses above 10 mg twice daily has not been evaluated in clinical studies [see Clinical Studies ( 14.1 )] . 2.3 Bipolar I Disorder Acute Treatment of Manic or Mixed Episodes : Monotherapy in Adults : The recommended starting and treatment dose of asenapine is 5 mg to 10 mg twice daily. The safety of doses above 10 mg twice daily has not been evaluated in clinical trials [see Clinical Studies ( 14.2 )] . Monotherapy in Pediatric P atients: The recommended dose of asenapine is 2.5 mg to 10 mg twice daily in pediatric patients 10 to 17 years of age, and dose may be adjusted for individual response and tolerability. The starting dose of asenapine is 2.5 mg twice daily. After 3 days, the dose can be increased to 5 mg twice daily, and from 5 mg to 10 mg twice daily after 3 additional days. Pediatric patients aged 10 to 17 years appear to be more sensitive to dystonia with initial dosing with asenapine when the recommended escalation schedule is not followed [see Use in Specific Populations ( 8.4 )] . The safety of doses greater than 10 mg twice daily has not been evaluated in clinical trials [see Use in Specific Populations ( 8.4 ) and Clinical Pharmacology ( 12.3 )] . Adjunctive Therapy in Adults : The recommended starting dose of asenapine is 5 mg twice daily when administered as adjunctive therapy with either lithium or valproate. Depending on the clinical response and tolerability in the individual patient, the dose can be increased to 10 mg twice daily. The safety of doses above 10 mg twice daily as adjunctive therapy with lithium or valproate has not been evaluated in clinical trials. For patients on asenapine, whether used as monotherapy or as adjunctive therapy with lithium or valproate, it is generally recommended that responding patients continue treatment beyond the acute episode. Maintenance Treatment of Bipolar I Disorder: Monotherapy in Adults: Continue on the asenapine dose that the patient received during stabilization (5 mg to 10 mg twice daily). Depending on the clinical response and tolerability in the individual patient, a dose of 10 mg twice daily can be decreased to 5 mg twice daily. The safety of doses above 10 mg twice daily has not been evaluated in clinical trials [see Clinical Studies ( 14.2 )].

9.2 Abuse Asenapine has not been systematically studied in animals or humans for its abuse potential or its ability to induce tolerance or physical dependence. Thus, it is not possible to predict the extent to which a CNS-active drug will be misused, diverted and/or abused once it is marketed. Patients should be evaluated carefully for a history of drug abuse, and such patients should be observed carefully for signs that they are misusing or abusing asenapine (e.g., drug-seeking behavior, increases in dose).

9.1 Controlled Substance Asenapine sublingual tablets are not a controlled substance.

9 DRUG ABUSE AND DEPENDENCE 9.1 Controlled Substance Asenapine sublingual tablets are not a controlled substance. 9.2 Abuse Asenapine has not been systematically studied in animals or humans for its abuse potential or its ability to induce tolerance or physical dependence. Thus, it is not possible to predict the extent to which a CNS-active drug will be misused, diverted and/or abused once it is marketed. Patients should be evaluated carefully for a history of drug abuse, and such patients should be observed carefully for signs that they are misusing or abusing asenapine (e.g., drug-seeking behavior, increases in dose).

10 OVERDOSAGE Human Experience: In adult pre-marketing clinical studies involving more than 3,350 patients and/or healthy subjects, accidental or intentional acute overdosage of asenapine was identified in 3 patients. Among these few reported cases of overdose, the highest estimated ingestion of asenapine was 400 mg. Reported adverse reactions at the highest dosage included agitation and confusion. Management of Overdosage: There is no specific antidote to asenapine. The possibility of multiple drug involvement should be considered. An electrocardiogram should be obtained and management of overdose should concentrate on supportive therapy, maintaining an adequate airway, oxygenation and ventilation, and management of symptoms. Consult with a Certified Poison Control Center for up-to-date guidance and advice on the management of overdosage (1-800-222-1222.) Hypotension and circulatory collapse should be treated with appropriate measures, such as intravenous fluids and/or sympathomimetic agents (epinephrine and dopamine should not be used, since beta stimulation may worsen hypotension in the setting of asenapine-induced alpha blockade). In case of severe extrapyramidal symptoms, anticholinergic medication should be administered. Close medical supervision and monitoring should continue until the patient recovers.

7 DRUG INTERACTIONS Antihypertensive Drugs: Asenapine may cause hypotension. ( 5.7 , 7.1 , 12.3 ) Paroxetine (CYP2D6 substrate and inhibitor): Reduce paroxetine by half when used in combination with asenapine. ( 7.1 , 12.3 ) 7.1 Drugs Having Clinically Important Drug Interactions with Asenapine Table 12 : Clinically Important Drug Interactions with Asenapine Concomitant Drug Name or Drug Class Clinical Rationale Clinical Recommendation Antihypertensive Drugs Because of its α 1 -adrenergic antagonism with potential for inducing hypotension, Asenapine may enhance the effects of certain antihypertensive agents [see Warnings and Precautions ( 5.7 )] . Monitor blood pressure and adjust dosage of antihypertensive drug accordingly. Strong CYP1A2 Inhibitors (e.g., Fluvoxamine) Asenapine is metabolized by CYP1A2. Marginal increase of asenapine exposure was observed when Asenapine is used with fluvoxamine at 25 mg administered twice daily [ see Clinical Pharmacology ( 12.3 )] . However, the tested fluvoxamine dose was suboptimal. Full therapeutic dose of fluvoxamine is expected to cause a greater increase in asenapine exposure. Dosage reduction for Asenapine based on clinical response may be necessary. CYP2D6 substrates and inhibitors (e.g., paroxetine) Asenapine may enhance the inhibitory effects of paroxetine on its own metabolism. Concomitant use of paroxetine with asenapine increased the paroxetine exposure by 2-fold as compared to use paroxetine alone [see Clinical Pharmacology ( 12.3 )]. Reduce paroxetine dose by half when paroxetine is used in combination with asenapine. 7.2 Drugs Having No Clinically Important Interactions with Asenapine No dosage adjustment of asenapine is necessary when administered concomitantly with paroxetine (see Table 12 in Drug Interactions ( 7.1 ) for paroxetine dosage adjustment), imipramine, cimetidine, valproate, lithium, or a CYP3A4 inducer (e.g., carbamazepine, phenytoin, rifampin). In addition, valproic acid and lithium pre-dose serum concentrations collected from an adjunctive therapy study were comparable between asenapine-treated patients and placebo-treated patients indicating a lack of effect of asenapine on valproic and lithium plasma levels.

12 CLINICAL PHARMACOLOGY Figure 1 Figure 2 Figure 3 12.1 Mechanism of Action The mechanism of action of asenapine, in schizophrenia and bipolar I disorder, is unknown. It has been suggested that the efficacy of asenapine in schizophrenia could be mediated through a combination of antagonist activity at D 2 and 5-HT 2A receptors. 12.2 Pharmacodynamics Asenapine exhibits high affinity for serotonin 5-HT 1A , 5-HT 1B , 5-HT 2A , 5-HT 2B , 5-HT 2C , 5-HT 5A , 5-HT 6, and 5-HT 7 receptors (Ki values of 2.5, 2.7, 0.07, 0.18, 0.03, 1.6, 0.25, and 0.11 nM, respectively), dopamine D 2A , D 2B , D 3 , D 4 , and D 1 receptors (Ki values of 1.3, 1.4, 0.42, 1.1, and 1.4 nM, respectively), α 1A , α 2A , α 2B , and α 2C -adrenergic receptors (Ki values of 1.2, 1.2, 0.33 and 1.2 nM, respectively), and histamine H 1 receptors (Ki value 1.0 nM), and moderate affinity for H 2 receptors (Ki value of 6.2 nM). In in vitro assays asenapine acts as an antagonist at these receptors. Asenapine has no appreciable affinity for muscarinic cholinergic receptors (e.g., Ki value of 8128 nM for M 1 ). 12.3 Pharmacokinetics Following a single 5 mg dose of asenapine, the mean C max was approximately 4 ng/mL and was observed at a mean t max of 1 hour. Elimination of asenapine is primarily through direct glucuronidation by UGT1A4 and oxidative metabolism by cytochrome P450 isoenzymes (predominantly CYP1A2). Following an initial more rapid distribution phase, the mean terminal half-life is approximately 24 hrs. With multiple-dose twice-daily dosing, steady-state is attained within 3 days. Overall, steady-state asenapine pharmacokinetics are similar to single-dose pharmacokinetics. Absorption: Following sublingual administration, asenapine is rapidly absorbed with peak plasma concentrations occurring within 0.5 to 1.5 hours. The absolute bioavailability of sublingual asenapine at 5 mg is 35%. Increasing the dose from 5 mg to 10 mg twice daily (a two-fold increase) results in less than linear (1.7 times) increases in both the extent of exposure and maximum concentration. The absolute bioavailability of asenapine when swallowed is low (<2% with an oral tablet formulation). The intake of water several (2 or 5) minutes after asenapine administration resulted in decreased asenapine exposure. Therefore, eating and drinking should be avoided for 10 minutes after administration [see Dosage and Administration ( 2.1 )] . Distribution: Asenapine is rapidly distributed and has a large volume of distribution (approximately 20 - 25 L/kg), indicating extensive extravascular distribution. Asenapine is highly bound (95%) to plasma proteins, including albumin and α 1 -acid glycoprotein. Metabolism and Elimination: Direct glucuronidation by UGT1A4 and oxidative metabolism by cytochrome P450 isoenzymes (predominantly CYP1A2) are the primary metabolic pathways for asenapine. Asenapine is a high clearance drug with a clearance after intravenous administration of 52 L/h. In this circumstance, hepatic clearance is influenced primarily by changes in liver blood flow rather than by changes in the intrinsic clearance, i.e., the metabolizing enzymatic activity. Following an initial more rapid distribution phase, the terminal half-life of asenapine is approximately 24 hours. Steady-state concentrations of asenapine are reached within 3 days of twice daily dosing. After administration of a single dose of [ 14 C]-labeled asenapine, about 90% of the dose was recovered; approximately 50% was recovered in urine, and 40% recovered in feces. About 50% of the circulating species in plasma have been identified. The predominant species was asenapine N + -glucuronide; others included N-desmethylasenapine, N-desmethylasenapine N-carbamoyl glucuronide, and unchanged asenapine in smaller amounts. Asenapine activity is primarily due to the parent drug. In vitro studies indicate that asenapine is a substrate for UGT1A4, CYP1A2 and to a lesser extent CYP3A4 and CYP2D6. Asenapine is a weak inhibitor of CYP2D6. Asenapine does not cause induction of CYP1A2 or CYP3A4 activities in cultured human hepatocytes. Coadministration of asenapine with known inhibitors, inducers or substrates of these metabolic pathways has been studied in a number of drug-drug interaction studies [ see Drug Interactions ( 7.1 )] . Food: A crossover study in 26 healthy adult male subjects was performed to evaluate the effect of food on the pharmacokinetics of a single 5 mg dose of asenapine. Consumption of food immediately prior to sublingual administration decreased asenapine exposure by 20%; consumption of food 4 hours after sublingual administration decreased asenapine exposure by about 10%. These effects are probably due to increased hepatic blood flow. In clinical trials establishing the efficacy and safety of asenapine, patients were instructed to avoid eating for 10 minutes following sublingual dosing. There were no other restrictions with regard to the timing of meals in these trials [ see Dosage and Administration ( 2.1 ) ] . Water: In clinical trials establishing the efficacy and safety of asenapine, patients were instructed to avoid drinking for 10 minutes following sublingual dosing. The effect of water administration following 10 mg sublingual asenapine dosing was studied at different time points of 2, 5, 10, and 30 minutes in 15 healthy adult male subjects. The exposure of asenapine following administration of water 10 minutes after sublingual dosing was equivalent to that when water was administered 30 minutes after dosing. Reduced exposure to asenapine was observed following water administration at 2 minutes (19% decrease) and 5 minutes (10% decrease) [ see Dosage and Administration ( 2.1 ) ] . Drug Interaction Studies: Effects of other drugs on the exposure of asenapine are summarized in Figure 1. In addition, a population pharmacokinetic analysis indicated that the concomitant administration of lithium had no effect on the pharmacokinetics of asenapine. Figure 1: Effect of Other Drugs on Asenapine Pharmacokinetics The effects of asenapine on the pharmacokinetics of other co-administered drugs are summarized in Figure 2. Coadministration of paroxetine with asenapine caused a two-fold increase in the maximum plasma concentrations and systemic exposure of paroxetine. Asenapine enhances the inhibitory effects of paroxetine on its own metabolism by CYP2D6. Figure 2: Effect of Asenapine on Other Drug Pharmacokinetics Studies in Special Populations: Exposures of asenapine in special populations are summarized in Figure 3. Additionally, based on population pharmacokinetic analysis, no effects of sex, race, BMI, and smoking status on asenapine exposure were observed. Exposure in elderly patients is 30-40% higher as compared to adults. Figure 3: Effect of Intrinsic Factors on Asenapine Pharmacokinetics

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis: In a lifetime carcinogenicity study in CD-1 mice asenapine was administered subcutaneously at doses up to those resulting in plasma levels (AUC) estimated to be 5 times those in humans receiving the MRHD of 10 mg twice daily. The incidence of malignant lymphomas was increased in female mice, with a no-effect dose resulting in plasma levels estimated to be 1.5 times those in humans receiving the MRHD. The mouse strain used has a high and variable incidence of malignant lymphomas, and the significance of these results to humans is unknown. There were no increases in other tumor types in female mice. In male mice, there were no increases in any tumor type. In a lifetime carcinogenicity study in Sprague-Dawley rats, asenapine did not cause any increases in tumors when administered subcutaneously at doses up to those resulting in plasma levels (AUC) estimated to be 5 times those in humans receiving the MRHD. Mutagenesis: No evidence for genotoxic potential of asenapine was found in the in vitro bacterial reverse mutation assay, the in vitro forward gene mutation assay in mouse lymphoma cells, the in vitro chromosomal aberration assays in human lymphocytes, the in vitro sister chromatid exchange assay in rabbit lymphocytes, or the in vivo micronucleus assay in rats. Impairment of Fertility: Asenapine did not impair fertility in rats when tested at doses up to 11 mg/kg twice daily given orally. This dose is 10 times the maximum recommended human dose of 10 mg twice daily given sublingually on a mg/m 2 basis.

14 CLINICAL STUDIES Efficacy of asenapinewas established in the following trials: Two fixed-dose, short-term trials and one flexible-dose, maintenance trial in adult patients with schizophrenia as monotherapy [ see Clinical Studies ( 14.1 )] One fixed-dose and two flexible-dose, short-term trials of monotherapy in adults with manic or mixed episodes associated with bipolar I disorder [see Clinical Studies ( 14.2 )] One flexible-dose, maintenance trial of monotherapy in adults with bipolar I disorder [see Clinical Studies ( 14.2 )] One fixed-dose, short term trial of monotherapy in children (10 to 17 years) with manic or mixed episodes associated with bipolar I disorder [see Clinical Studies ( 14.2 )] One flexible-dose, short-term trial in adult patients with manic or mixed episode associated with bipolar I disorder as adjunctive treatment to lithium or valproate [see Clinical Studies ( 14.2 )] Figure 4 Figure 5 14.1 Schizophrenia The efficacy of asenapine in the treatment of schizophrenia in adults was evaluated in three fixed-dose, short-term (6 week), randomized, double-blind, placebo-controlled, and active-controlled (haloperidol, risperidone, and olanzapine) trials of adult patients who met DSM-IV criteria for schizophrenia and were having an acute exacerbation of their schizophrenic illness. In two of the three trials asenapine demonstrated superior efficacy to placebo. In a third trial, asenapine could not be distinguished from placebo; however, an active control in that trial was superior to placebo. In the two positive trials for asenapine, the primary efficacy rating scale was the Positive and Negative Syndrome Scale (PANSS). The PANSS is a 30 item scale that measures positive symptoms of schizophrenia (7 items), negative symptoms of schizophrenia (7 items), and general psychopathology (16 items), each rated on a scale of 1 (absent) to 7 (extreme); total PANSS scores range from 30 to 210. The primary endpoint was change from baseline to endpoint on the PANSS total score. The results of the asenapine trials in schizophrenia follow: In trial 1, a 6-week trial (n=174), comparing asenapine (5 mg twice daily) to placebo, asenapine 5 mg twice daily was statistically superior to placebo on the PANSS total score (Trial 1 in Table 13). In trial 2, a 6-week trial (n=448), comparing two fixed doses of asenapine (5 mg and 10 mg twice daily) to placebo, asenapine 5 mg twice daily was statistically superior to placebo on the PANSS total score. Asenapine 10 mg twice daily showed no added benefit compared to 5 mg twice daily and was not significantly different from placebo (Trial 2 in Table 13). An examination of population subgroups did not reveal any clear evidence of differential responsiveness on the basis of age, sex or race.

Maintenance of efficacy has been demonstrated in a placebo-controlled, double-blind, multicenter, flexible dose (5 mg or 10 mg twice daily based on tolerability) clinical trial with a randomized withdrawal design. All patients were initially administered 5 mg twice daily for 1 week and then titrated up to 10 mg twice daily. A total of 700 patients entered open-label treatment with asenapine for a period of 26 weeks. Of these, a total of 386 patients who met pre-specified criteria for continued stability (mean length of stabilization was 22 weeks) were randomized to a double-blind, placebo-controlled, randomized withdrawal phase. Asenapine was statistically superior to placebo in time to relapse or impending relapse defined as increase in PANSS ≥20% from baseline and a Clinical Global Impression–Severity of Illness (CGI-S) score ≥4 (at least 2 days within 1 week) or PANSS score ≥5 on “hostility” or “uncooperativeness” items and CGI-S score ≥4 (≥2 days within a week), or PANSS score ≥5 on any two of the following items: “unusual thought content”, “conceptual disorganization”, or “hallucinatory behavior” items, and CGI-S score ≥4 (≥2 days within 1 week) or investigator judgment of worsening symptoms or increased risk of violence to self (including suicide) or other persons. The Kaplan-Meier curves of the time to relapse or impending relapse during the double-blind, placebo-controlled, randomized withdrawal phase of this trial for asenapine and placebo are shown in Figure 4. Figure 4: Kaplan-Meier Estimation of Percent Relapse/Impending Relapse for a senapine and placebo 14.2 Bipolar I Disorder Monotherapy Adults : The efficacy of asenapine in the treatment of acute mania was established in two similarly designed 3-week, randomized, double-blind, placebo-controlled, and active-controlled (olanzapine) trials of adult patients who met DSM-IV criteria for Bipolar I Disorder with an acute manic or mixed episode with or without psychotic features. The primary rating instrument used for assessing manic symptoms in these trials was the Young Mania Rating Scale (YMRS), an 11-item clinician-rated scale traditionally used to assess the degree of manic symptomatology in a range from 0 (no manic features) to 60 (maximum score). Patients were also assessed on the Clinical Global Impression – Bipolar (CGI-BP) scale. In both trials, all patients randomized to asenapine were initially administered 10 mg twice daily, and the dose could be adjusted within the dose range of 5 to 10 mg twice daily from Day 2 onward based on efficacy and tolerability. Ninety percent of patients remained on the 10 mg twice daily dose. Asenapine was statistically superior to placebo on the YMRS total score and the CGI-BP Severity of Illness score (mania) in both studies (Trials 1 and 2 in Table 14). In another 3-week, randomized, double-blind, placebo-controlled trial (n=359), comparing two fixed doses of asenapine (5 mg and 10 mg twice daily) to placebo, both doses were statistically superior to placebo on the YMRS total score and CGI-BP Severity of Illness overall score. (Trial 3 in Table 14). An examination of subgroups did not reveal any clear evidence of differential responsiveness on the basis of age, sex, or race. Maintenance of efficacy has been demonstrated in a placebo-controlled, double-blind, multicenter, flexible dose (5 mg or 10 mg twice daily based on tolerability) clinical trial with a randomized withdrawal design. All patients were initially administered 5 or 10 mg twice daily, and the option to titrate down to 5 mg twice daily was provided based on tolerability. A total of 549 patients entered open-label treatment with asenapine for a period of 12 to 16 weeks. Of these, a total of 252 patients who met pre-specified criteria for continued stability were randomized to and treated in a double-blind, placebo-controlled, randomized withdrawal phase. Asenapine was statistically superior to placebo in time to relapse defined as 1) YMRS or MADRS score ≥ 16; 2) requirement or initiation of any non-study medication to treat mixed, manic, or depressive symptoms, including an antipsychotic, antidepressant, or mood-stabilizing agent; 3) requirement or initiation of psychiatric hospitalization; 4) investigator judgment to discontinue the study due to a mood event. The Kaplan-Meier curves of the time to relapse during the double-blind, placebo-controlled, randomized withdrawal phase of this trial for asenapine and placebo are shown in Figure 5. Figure 5: Kaplan-Meier Estimation of Percent Relapse for Asenapine and P lacebo Time (days) represents the number of days from randomization in the double-blind period to the first date of achieving relapse status. The product limit estimators are based on the Kaplan-Meier distribution with censoring at last contact date. Pediatric patients: The efficacy of asenapine in the treatment of acute mania was established in a single, 3-week, placebo-controlled, double-blind trial of 403 pediatric patients 10 to 17 years of age, of whom 302 patients received asenapine at fixed doses of 2.5 mg, 5 mg and 10 mg twice daily. All patients were started on 2.5 mg twice daily. For those assigned to 5 mg twice daily, the dose was increased to 5 mg twice daily after 3 days. For those assigned to 10 mg twice daily, the dose was increased from 2.5 to 5 mg twice daily after 3 days, and then to 10 mg twice daily after 3 additional days. Asenapine was statistically superior to placebo in improving YMRS total score and the CGI-BP Severity of Illness overall score as measured by the change from baseline to week 3 (Trial 3 Pediatric in Table 14). An examination of subgroups did not reveal any clear evidence of differential responsiveness on the basis of age, sex, and race. Adjunctive Therapy: The efficacy of asenapine as an adjunctive therapy in acute mania was established in a 12-week, placebo-controlled trial with a 3-week primary efficacy endpoint involving 326 adult patients with a manic or mixed episode of Bipolar I Disorder, with or without psychotic features, who were partially responsive to lithium or valproate monotherapy after at least 2 weeks of treatment. All patients randomized to asenapine were initially administered 5 mg twice daily, and the dose could be adjusted within the dose range of 5 to 10 mg twice daily from Day 2 onward based on efficacy and tolerability. Asenapine was statistically superior to placebo in the reduction of manic symptoms (measured by the YMRS total score) as an adjunctive therapy to lithium or valproate monotherapy at Week 3 (Trial 5 Adjunctive in Table 14).

8.5 Geriatric Use Clinical studies of asenapine in the treatment of schizophrenia and bipolar mania did not include sufficient numbers of patients aged 65 and over to determine whether or not they respond differently than younger patients. Of the approximately 2,250 patients in pre-marketing clinical studies of asenapine, 1.1% (25) were 65 years of age or over. Multiple factors that might increase the pharmacodynamic response to asenapine, causing poorer tolerance or orthostasis, could be present in elderly patients, and these patients should be monitored carefully. Based on a pharmacokinetic study in elderly patients, dosage adjustments are not recommended based on age alone [see Clinical Pharmacology ( 12.3 )] . Elderly patients with dementia-related psychosis treated with asenapine are at an increased risk of death compared to placebo. Asenapine is not approved for the treatment of patients with dementia-related psychosis [ see Boxed Warning ] .

8.4 Pediatric Use Safety and efficacy of asenapine in pediatric patients below the age of 10 years of age have not been evaluated. Bipolar I Disorder The safety and efficacy of asenapine as monotherapy in the treatment of bipolar I disorder were established in a 3-week, placebo-controlled, double-blind trial of 403 pediatric patients 10 to 17 years of age, of whom 302 patients received asenapine at fixed doses ranging from 2.5 mg to 10 mg twice daily [see Dosage and Administration ( 2.3 ), Adverse Reactions ( 6.1 ), Clinical Pharmacology ( 12.3 ), and Clinical Studies ( 14.2 )] . In a Phase 1 study, pediatric patients aged 10 to 17 years appeared to be more sensitive to dystonia with initial dosing with asenapine when the recommended dose escalation schedule was not followed. Similar safety findings were reported from a 50-week, open-label, uncontrolled safety trial in pediatric patients with bipolar I disorder treated with asenapine monotherapy. The safety and efficacy of asenapine as adjunctive therapy in the treatment of bipolar I disorder have not been established in the pediatric population. In general, the pharmacokinetics of asenapine in pediatric patients (10 to 17 years) and adults are similar [see Clinical Pharmacology ( 12.3 )] . Schizophrenia Efficacy of asenapine was not demonstrated in an 8-week, placebo-controlled, double-blind trial, in 306 adolescent patients aged 12 to 17 years with schizophrenia at doses of 2.5 and 5 mg twice daily. The most common adverse reactions (proportion of patients equal or greater than 5% and at least twice placebo) reported were somnolence, akathisia, dizziness, and oral hypoesthesia or paresthesia. The proportion of patients with an equal or greater than 7% increase in body weight at endpoint compared to baseline for placebo, asenapine 2.5 mg twice daily, and asenapine 5 mg twice daily was 3%, 10%, and 10%, respectively. The clinically relevant adverse reactions identified in the pediatric schizophrenia trial were generally similar to those observed in the pediatric bipolar I and adult bipolar I and schizophrenia trials. No new major safety findings were reported from a 26-week, open-label, uncontrolled safety trial in pediatric patients with schizophrenia treated with asenapine monotherapy. Juvenile Animal Data Subcutaneous administration of asenapine to juvenile rats for 56 days from day 14 of age to day 69 of age at 0.4, 1.2, and 3.2 mg/kg/day (0.2, 0.6 and 1.5 times the maximum recommended human dose of 10 mg twice daily given sublingually on a mg/m 2 basis) resulted in significant reduction in body weight gain in animals of both sexes at all dose levels from the start of dosing until weaning. Body weight gain remained reduced in males to the end of treatment, however, recovery was observed once treatment ended. Neurobehavioral assessment indicated increased motor activity in animals at all dose levels following the completion of treatment, with the evidence of recovery in males. There was no recovery after the end of treatment in female activity pattern as late as day 30 following the completion of treatment (last retesting). Therefore, a No Observed Adverse Effect Level (NOAEL) for the juvenile animal toxicity of asenapine could not be determined. There were no treatment-related effects on the startle response, learning/memory, organ weights, microscopic evaluations of the brain and, reproductive performance (except for minimally reduced conception rate and fertility index in males and females administered 1.2 and 3.2 mg/kg/day).

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to asenapine during pregnancy. For more information contact the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/ . Risk Summary Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms. Studies have not been conducted with asenapine in pregnant women. There are no available human data informing the drug-associated risk. The background risk of major birth defects and miscarriage for the indicated populations are unknown. However, the background risk in the U.S. general population of major birth defects is 2-4% and of miscarriage is 15-20% of clinically recognized pregnancies. No teratogenicity was observed in animal reproduction studies with intravenous administration of asenapine to rats and rabbits during organogenesis at doses 0.7 and 0.4 times, respectively, the maximum recommended human dose (MRHD) of 10 mg sublingually twice daily. In a pre-and post-natal study in rats, intravenous administration of asenapine at doses up to 0.7 times the MRHD produced increases in post-implantation loss and early pup deaths, and decreases in subsequent pup survival and weight gain [see Data]. Advise pregnant women of the potential risk to a fetus. Clinical Considerations Fetal/Neonatal Adverse Reactions Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs during the third trimester of pregnancy. These symptoms have varied in severity. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. Data Animal Data In animal studies, asenapine increased post-implantation loss and decreased pup weight and survival at doses similar to or less than recommended clinical doses. In these studies there was no increase in the incidence of structural abnormalities caused by asenapine. Asenapine was not teratogenic in reproduction studies in rats and rabbits at intravenous doses up to 1.5 mg/kg in rats and 0.44 mg/kg in rabbits administered during organogenesis. These doses are 0.7 and 0.4 times, respectively, the maximum recommended human dose (MRHD) of 10 mg twice daily given sublingually on a mg/m 2 basis. Plasma levels of asenapine were measured in the rabbit study, and the area under the curve (AUC) at the highest dose tested was 2 times that in humans receiving the MRHD. In a study in which rats were treated from day 6 of gestation through day 21 postpartum with intravenous doses of asenapine of 0.3, 0.9, and 1.5 mg/kg/day (0.15, 0.4, and 0.7 times the MRHD of 10 mg twice daily given sublingually on a mg/m 2 basis), increases in post-implantation loss and early pup deaths were seen at all doses, and decreases in subsequent pup survival and weight gain were seen at the two higher doses. A cross-fostering study indicated that the decreases in pup survival were largely due to prenatal drug effects. Increases in post-implantation loss and decreases in pup weight and survival were also seen when pregnant rats were dosed orally with asenapine.

Asenapine is excreted in rat milk. The development and health benefits of breastfeeding should be considered along with the mother’s clinical need for asenapine and any potential adverse effects on the breastfed infant from asenapine or from the underlying maternal condition. 8.4 Pediatric Use Safety and efficacy of asenapine in pediatric patients below the age of 10 years of age have not been evaluated. Bipolar I Disorder The safety and efficacy of asenapine as monotherapy in the treatment of bipolar I disorder were established in a 3-week, placebo-controlled, double-blind trial of 403 pediatric patients 10 to 17 years of age, of whom 302 patients received asenapine at fixed doses ranging from 2.5 mg to 10 mg twice daily [see Dosage and Administration ( 2.3 ), Adverse Reactions ( 6.1 ), Clinical Pharmacology ( 12.3 ), and Clinical Studies ( 14.2 )] . In a Phase 1 study, pediatric patients aged 10 to 17 years appeared to be more sensitive to dystonia with initial dosing with asenapine when the recommended dose escalation schedule was not followed. Similar safety findings were reported from a 50-week, open-label, uncontrolled safety trial in pediatric patients with bipolar I disorder treated with asenapine monotherapy. The safety and efficacy of asenapine as adjunctive therapy in the treatment of bipolar I disorder have not been established in the pediatric population. In general, the pharmacokinetics of asenapine in pediatric patients (10 to 17 years) and adults are similar [see Clinical Pharmacology ( 12.3 )] . Schizophrenia Efficacy of asenapine was not demonstrated in an 8-week, placebo-controlled, double-blind trial, in 306 adolescent patients aged 12 to 17 years with schizophrenia at doses of 2.5 and 5 mg twice daily.

The proportion of patients with an equal or greater than 7% increase in body weight at endpoint compared to baseline for placebo, asenapine 2.5 mg twice daily, and asenapine 5 mg twice daily was 3%, 10%, and 10%, respectively. The clinically relevant adverse reactions identified in the pediatric schizophrenia trial were generally similar to those observed in the pediatric bipolar I and adult bipolar I and schizophrenia trials. No new major safety findings were reported from a 26-week, open-label, uncontrolled safety trial in pediatric patients with schizophrenia treated with asenapine monotherapy.

Elderly patients with dementia-related psychosis treated with asenapine are at an increased risk of death compared to placebo. Asenapine is not approved for the treatment of patients with dementia-related psychosis [ see Boxed Warning ] . 8.6 Renal Impairment No dosage adjustment for asenapine is required on the basis of a patient’s renal function (mild to severe renal impairment, glomerular filtration rate between 15 and 90 mL/minute). The exposure of asenapine was similar among subjects with varying degrees of renal impairment and subjects with normal renal function [ see Clinical Pharmacology ( 12.3 )] . The effect of renal function on the excretion of other metabolites and the effect of dialysis on the pharmacokinetics of asenapine has not been studied. 8.7 Hepatic Impairment Asenapine is contraindicated in patients with severe hepatic impairment (Child-Pugh C) because asenapine exposure is 7-fold higher in subjects with severe hepatic impairment than the exposure observed in subjects with normal hepatic function. No dosage adjustment for asenapine is required in patients with mild to moderate hepatic impairment (Child-Pugh A and B) because asenapine exposure is similar to that in subjects with normal hepatic function [ see Contraindications ( 4 ) and Clinical Pharmacology ( 12.3 )] . 8.8 Other Specific Populations No dosage adjustment for asenapine is required on the basis of a patient’s sex, race (Caucasian and Japanese), or smoking status [see Clinical Pharmacology ( 12.3 )] .
