5.1Increased Mortality in Elderly Patients with Dementia-Related Psychosis
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of 17 placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in the drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group.
Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Asenapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning and Warnings and Precautions ( 5.2 )].
5.2Cerebrovascular Adverse Events, Including Stroke, In Elderly Patients with Dementia-Related Psychosis
In placebo-controlled trials in elderly subjects with dementia, patients randomized to risperidone, aripiprazole, and olanzapine had a higher incidence of stroke and transient ischemic attacks, including fatal stroke. Asenapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning and Warnings and Precautions ( 5.1 )].
5.3Neuroleptic Malignant Syndrome
A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with administration of antipsychotic drugs. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, delirium and autonomic instability. Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure. If NMS is suspected, immediately discontinue asenapine and provide intensive symptomatic treatment and monitoring.
5.4Tardive Dyskinesia
Tardive dyskinesia, a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements, may develop in patients treated with antipsychotic drugs, including asenapine. The risk appears to be highest among the elderly, especially elderly women, but it is not possible to predict which patients are likely to develop the syndrome. Whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown.
The risk of tardive dyskinesia and the likelihood that it will become irreversible increase with the duration of treatment and the cumulative dose. The syndrome can develop after a relatively brief treatment period, even at low doses. It may also occur after discontinuation of treatment. There is no known treatment for tardive dyskinesia, although the syndrome may remit, partially or completely, if antipsychotic treatment is discontinued.
Antipsychotic treatment itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome, possibly masking the underlying process. The effect that symptomatic suppression has upon the long-term course of tardive dyskinesia is unknown. Given these considerations, asenapine should be prescribed in a manner most likely to reduce the risk of tardive dyskinesia. Chronic antipsychotic treatment should generally be reserved for patients: 1) who suffer from a chronic illness that is known to respond to antipsychotic drugs; and 2) for whom alternative, effective, but potentially less harmful treatments are not available or appropriate.
In patients who do require chronic treatment, use the lowest dose and the shortest duration of treatment producing a satisfactory clinical response should be sought. Periodically reassess the need for continued treatment. If signs and symptoms of TD appear in a patient on asenapine, drug discontinuation should be considered. However, some patients may require treatment with asenapine despite the presence of the syndrome.
5.5Metabolic Changes
Atypical antipsychotic drugs, including asenapine, have caused metabolic changes, including hyperglycemia, diabetes mellitus, dyslipidemia, and body weight gain. Although all of the drugs in the class to date have been shown to produce some metabolic changes, each drug has its own specific risk profile. Hyperglycemia and Diabetes Mellitus Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics.
There have been reports of hyperglycemia in patients treated with asenapine. Assess fasting plasma glucose before or soon after initiation of antipsychotic medication, and monitor periodically during long-term treatment. Adult Patients: Pooled data from the short-term placebo-controlled bipolar mania trials are presented in Table 1 . TABLE 1: Changes in Fasting Glucose in Adult Patients Bipolar I Disorder (3-weeks) Placebo Asenapine 5 mg twice daily 10 mg twice daily Asenapine 5 or 10 mg twice daily † Mean Change from Baseline in Fasting Glucose at Endpoint Change from Baseline (mg/dL) (N*) 0 (174) 4.1 (84) 3.5 (81) 1.7 (321) Proportion of Patients with Shifts from Baseline to Endpoint Normal to High <100 to ≥126 mg/dL (n/N**) 2.4% (3/126) 0% (0/53) 1.7% (1/60) 1.8% (4/224) Borderline to High ≥100 and <126 to ≥126 mg/dL (n/N**) 0% (0/39) 12.5% (3/24) 15.8% (3/19) 12.8% (10/78) N* = Number of patients who had assessments at both Baseline and Endpoint.

In a 52-week, double-blind, comparator-controlled trial, the mean increase from baseline of fasting glucose was 2.4 mg/dL. Dyslipidemia Atypical antipsychotics cause adverse alterations in lipids. Before or soon after initiation of antipsychotic medication, obtain a fasting lipid profile at baseline and monitor periodically during treatment.

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.
7.2Drugs 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.
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 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 10 mg twice daily dose for all of these most common adverse reactions. 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.
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 ): Bipolar I Disorder Adults (Adjunctive): somnolence, oral hypoesthesia.

6.1Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. 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 Asenapine-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 .
Table 11: Adverse Reactions Reported in 2% or More of Adult Patients In Any Asenapine-Dose Group and Which Occurred at Greater Incidence Than in the Placebo Group at 3 Weeks in Adjunctive Bipolar Mania Trials System Organ Class/Preferred Term Placebo N=166 % Asenapine 5 mg or 10 mg twice daily* N=158 % Gastrointestinal disorders Dyspepsia 2 3 Oral hypoesthesia 0 5 General disorders Fatigue 2 4 Edema peripheral <1 3 Investigations Increased weight 0 3 Nervous system disorders Dizziness 2 4 Other extrapyramidal symptoms (excluding akathisia) † 5 6 Somnolence ‡ 10 22 Psychiatric disorders Insomnia 8 10 Vascular disorders Hypertension <1 3 * Asenapine 5 mg to 10 mg twice daily with flexible dosing. † Extrapyramidal symptoms included: dystonia, parkinsonism, oculogyration, and tremor (excluding akathisia). ‡ Somnolence includes the following events: somnolence and sedation.
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 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 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 another study. 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 bipolar mania adult trials were more common in treated patients.
In short-term, placebo-controlled bipolar adult mania 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 another study.
In a 52-week, double-blind, comparator-controlled trial that included primarily adult patients, the mean increase from baseline of ALT was 1.7 units/L. Prolactin: In short-term, placebo-controlled bipolar mania adult trials, the mean increase in prolactin levels was 6.7 ng/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-tr
