6 ADVERSE REACTIONS 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.

The following adverse reactions are discussed in more detail in other sections of the labeling: Increased Mortality in Elderly Patients with Dementia-Related Psychosis [see Boxed Warning and Warnings and Precautions (5.1) ] Cerebrovascular Adverse Events, Including Stroke [see Warnings and Precautions (5.2) ] Suicidal Thoughts and Behaviors in Children, Adolescents, and Young Adults [see Boxed Warning and Warnings and Precautions (5.3) ] Neuroleptic Malignant Syndrome (NMS) [see Warnings and Precautions (5.4) ] Tardive Dyskinesia [see Warnings and Precautions (5.5) ] Metabolic Changes [see Warnings and Precautions (5.6) ] Pathological Gambling and Other Compulsive Behaviors [see Warnings and Precautions (5.7) ] Orthostatic Hypotension [see Warnings and Precautions (5.8) ] Falls [see Warnings and Precautions (5.9) ] Leukopenia, Neutropenia, and Agranulocytosis [see Warnings and Precautions (5.10) ] Seizures/Convulsions [see Warnings and Precautions (5.11) ] Potential for Cognitive and Motor Impairment [see Warnings and Precautions (5.12) ] Body Temperature Regulation [see Warnings and Precautions (5.13) ] Suicide [see Warnings and Precautions (5.14) ] Dysphagia [see Warnings and Precautions (5.15) ] The most common adverse reactions in adult patients in clinical trials (≥ 10%) were nausea, vomiting, constipation, headache, dizziness, akathisia, anxiety, insomnia, and restlessness.

The most common adverse reactions in the pediatric clinical trials (≥ 10%) were somnolence, headache, vomiting, extrapyramidal disorder, fatigue, increased appetite, insomnia, nausea, nasopharyngitis, and weight increased.

Aripiprazole has been evaluated for safety in 13,543 adult patients who participated in multiple-dose, clinical trials in schizophrenia, other indications, Dementia of the Alzheimer’s type, Parkinson’s disease, and alcoholism, and who had approximately 7,619 patient-years of exposure to oral aripiprazole.

A total of 3,390 patients were treated with oral aripiprazole for at least 180 days and 1,933 patients treated with oral aripiprazole had at least one year of exposure.

Aripiprazole has been evaluated for safety in 1,686 pediatric patients (6 to 18 years) who participated in multiple-dose, clinical trials in schizophrenia, autistic disorder, tourette’s disorder, or other indication and who had approximately 1,342 patient-years of exposure to oral aripiprazole.

A total of 959 pediatric patients were treated with oral aripiprazole for at least 180 days and 556 pediatric patients treated with oral aripiprazole had at least one year of exposure.

The conditions and duration of treatment with aripiprazole included (in overlapping categories) double-blind, comparative and noncomparative open-label studies, inpatient and outpatient studies, fixed- and flexible-dose studies, and short- and longer-term exposure.

This analysis, stratified by study, indicated that the only adverse reaction to have a possible dose response relationship, and then most prominent only with 30 mg, was somnolence [including sedation]; (incidences were placebo, 7.1%; 10 mg, 8.5%; 15 mg, 8.7%; 20 mg, 7.5%; 30 mg, 12.6%).

In the study of pediatric patients (13 to 17 years of age) with schizophrenia, three common adverse reactions appeared to have a possible dose response relationship: extrapyramidal disorder (incidences were placebo, 5.0%; 10 mg, 13.0%; 30 mg, 21.6%); somnolence (incidences were placebo, 6.0%; 10 mg, 11.0%; 30 mg, 21.6%); and tremor (incidences were placebo, 2.0%; 10 mg, 2.0%; 30 mg, 11.8%).

Autistic Disorder In a study of pediatric patients (6 to 17 years of age) with autistic disorder, one common adverse reaction had a possible dose response relationship: fatigue (incidences were placebo, 0%; 5 mg, 3.8%; 10 mg, 22.0%; 15 mg, 18.5%).

Tourette’s Disorder In a study of pediatric patients (7 to 17 years of age) with Tourette’s disorder, no common adverse reaction(s) had a dose response relationship.

Extrapyramidal Symptoms Schizophrenia In short-term, placebo-controlled trials in schizophrenia in adults, the incidence of reported EPS-related events, excluding events related to akathisia, for aripiprazole-treated patients was 13% vs.

12% for placebo; and the incidence of akathisia-related events for aripiprazole-treated patients was 8% vs.

4% for placebo.

In the short-term, placebo-controlled trial of schizophrenia in pediatric patients (13 to 17 years), the incidence of reported EPS-related events, excluding events related to akathisia, for aripiprazole-treated patients was 25% vs.

7% for placebo; and the incidence of akathisia-related events for aripiprazole-treated patients was 9% vs.

6% for placebo.

Objectively collected data from those trials was collected on the Simpson Angus Rating Scale (for EPS), the Barnes Akathisia Scale (for akathisia), and the Assessments of Involuntary Movement Scales (for dyskinesias).

In the adult schizophrenia trials, the objectively collected data did not show a difference between aripiprazole and placebo, with the exception of the Barnes Akathisia Scale (aripiprazole, 0.08; placebo, –0.05).

In the pediatric (13 to 17 years) schizophrenia trial, the objectively collected data did not show a difference between aripiprazole and placebo, with the exception of the Simpson Angus Rating Scale (aripiprazole, 0.24; placebo, –0.29).

Similarly, in a long-term (26 week), placebo-controlled trial of schizophrenia in adults, objectively collected data on the Simpson Angus Rating Scale (for EPS), the Barnes Akathisia Scale (for akathisia), and the Assessments of Involuntary Movement Scales (for dyskinesias) did not show a difference between aripiprazole and placebo.

Autistic Disorder In the short-term, placebo-controlled trials in autistic disorder in pediatric patients (6 to 17 years), the incidence of reported EPS-related events, excluding events related to akathisia, for aripiprazole-treated patients was 18% vs.

2% for placebo and the incidence of akathisia-related events for aripiprazole-treated patients was 3% vs.

9% for placebo.

In the pediatric (6 to 17 years) short-term autistic disorder trials, the Simpson Angus Rating Scale showed a significant difference between aripiprazole and placebo (aripiprazole, 0.1; placebo, – 0.4).

Changes in the Barnes Akathisia Scale and the Assessments of Involuntary Movement Scales were similar for the aripiprazole and placebo groups.

Tourette’s Disorder In the short-term, placebo-controlled trials in Tourette’s disorder in pediatric patients (6 to 18 years), the incidence of reported EPS-related events, excluding events related to akathisia, for aripiprazole-treated patients was 7% vs.

6% for placebo and the incidence of akathisia-related events for aripiprazole-treated patients was 4% vs.

6% for placebo.

In the pediatric (6 to 18 years) short-term Tourette’s disorder trials, changes in the Simpson Angus Rating Scale, Barnes Akathisia Scale and Assessments of Involuntary Movement Scale were not clinically meaningfully different for aripiprazole and placebo.

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.

Additional Findings Observed in Clinical Trials Adverse Reactions in Long-Term, Double-Blind, Placebo-Controlled Trials The adverse reactions reported in a 26 week, double-blind trial comparing oral aripiprazole and placebo in patients with schizophrenia were generally consistent with those reported in the short-term, placebo-controlled trials, except for a higher incidence of tremor [8% (12/153) for aripiprazole vs.

2% (3/153) for placebo].

In this study, the majority of the cases of tremor were of mild intensity (8/12 mild and 4/12 moderate), occurred early in therapy (9/12 ≤ 49 days), and were of limited duration (7/12 ≤ 10 days).

Tremor infrequently led to discontinuation (< 1%) of aripiprazole.

In addition, in a long-term (52 week), active-controlled study, the incidence of tremor was 5% (40/859) for aripiprazole.

A similar profile was observed in a long-term monotherapy study and a long-term adjunctive study with lithium and valproate in bipolar disorder.

Other Adverse Reactions Observed During the Clinical Trail Evaluation of Aripiprazole The following listing does not include reactions: 1) already listed in previous tables or elsewhere in labeling, 2) for which a drug cause was remote, 3) which were so general as to be uninformative, 4) which were not considered to have significant clinical implications, or 5) which occurred at a rate equal to or less than placebo.

Additional adverse reactions observed in the pediatric population are listed below.

Eye Disorders: infrequent - oculogyric crisis Gastrointestinal Disorders: infrequent -tongue dry, tongue spasm Investigations: frequent - blood insulin increased Nervous System Disorders: infrequent - sleep talking Renal and Urinary Disorders: frequent – enuresis Skin and Subcutaneous Tissue Disorders: infrequent - hirsutism 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of aripiprazole.

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: occurrences of allergic reaction (anaphylactic reaction, angioedema, laryngospasm, pruritus/urticaria, or oropharyngeal spasm), blood glucose fluctuation, Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), hiccups, oculogyric crisis, and pathological gambling.
