Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of ABILIFY MYCITE for the treatment of adults with schizophrenia, treatment of adults with manic and mixed episodes associated with bipolar I disorder, and adjunctive treatment of adults with major depressive disorder (MDD) has been established and is based on trials of aripiprazole including 13,543 adult patients who participated in multiple-dose, clinical trials in schizophrenia, bipolar disorder, major depressive disorder, and other disorders, and who had approximately 7619 patientyears of exposure to oral aripiprazole. A total of 3390 patients were treated with oral aripiprazole for at least 180 days and 1933 patients treated with oral aripiprazole had at least 1 year of exposure.

The conditions and duration of treatment with aripiprazole (monotherapy and adjunctive therapy with antidepressants or mood stabilizers) 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.

The most common adverse reactions of aripiprazole in adult patients in clinical trials (≥10%) were nausea, vomiting, constipation, headache, dizziness, akathisia, anxiety, insomnia, and restlessness.

Adverse Reactions In Adult Patients With Schizophrenia

The following findings are based on a pool of five placebo-controlled trials (four 4 week and one 6 week) in which oral aripiprazole was administered in doses ranging from 2 to 30 mg/day.

The commonly observed adverse reaction associated with the use of aripiprazole tablets in patients with schizophrenia (incidence of 5% or greater and aripiprazole tablets incidence at least twice that for placebo) was akathisia (aripiprazole tablets 8%; placebo 4%).

Adverse Reactions In Adult Patients With Bipolar Mania

Adult Patients Who Received Monotherapy

The following findings are based on a pool of 3 week, placebo-controlled, bipolar mania trials in which oral aripiprazole was administered at doses of 15 or 30 mg/day.

Commonly observed adverse reactions associated with the use of aripiprazole tablets in patients with bipolar mania (incidence of 5% or greater and aripiprazole tablets incidence at least twice that for placebo) are shown in Table 1.

Table 1: Commonly Observed Adverse Reactions in Short-Term, Placebo-Controlled Trials of Adult Patients with Bipolar Mania Treated with Oral Aripiprazole Monotherapy

Table 2 enumerates the pooled incidence, rounded to the nearest percent, of adverse reactions that occurred during acute therapy (up to 6 weeks in schizophrenia and up to 3 weeks in bipolar mania), including only those reactions that occurred in 2% or more of patients treated with aripiprazole tablets (doses ≥2 mg/day) and for which the incidence in patients treated with aripiprazole tablets was greater than the incidence in patients treated with placebo in the combined dataset.

Table 2: Adverse Reactions in Short-Term, Placebo- Controlled Trials in Adult Patients Treated with Oral Aripiprazole

An examination of population subgroups did not reveal any clear evidence of differential adverse reaction incidence on the basis of age, gender, or race.

Adult Patients with Adjunctive Therapy with Bipolar Mania

The following findings are based on a placebo-controlled trial of adult patients with bipolar disorder in which aripiprazole tablets was administered at doses of 15 or 30 mg/day as adjunctive therapy with lithium or valproate.

In a study of patients who were already tolerating either lithium or valproate as monotherapy, discontinuation rates due to adverse reactions were 12% for patients treated with adjunctive aripiprazole tablets compared to 6% for patients treated with adjunctive placebo. The most common adverse drug reactions associated with discontinuation in the adjunctive aripiprazole-treated compared to placebotreated patients were akathisia (5% and 1%, respectively) and tremor (2% and 1%, respectively).

The commonly observed adverse reactions associated with adjunctive aripiprazole tablets and lithium or valproate in patients with bipolar mania (incidence of 5% or greater and incidence at least twice that for adjunctive placebo) were: akathisia, insomnia, and extrapyramidal disorder.

Table 3 enumerates the incidence, rounded to the nearest percent, of adverse reactions that occurred during acute treatment (up to 6 weeks), including only those reactions that occurred in 2% or more of patients treated with adjunctive aripiprazole tablets (doses of 15 or 30 mg/day) and lithium or valproate and for which the incidence in patients treated with this combination was greater than the incidence in patients treated with placebo plus lithium or valproate.

Adult Patients Receiving Aripiprazole Tablets As Adjunctive Treatment Of Major Depressive Disorder

The following findings are based on a pool of two placebo-controlled trials of patients with major depressive disorder in which aripiprazole tablets were administered at doses of 2 mg to 20 mg as adjunctive treatment to continued antidepressant therapy.

The incidence of discontinuation due to adverse reactions was 6% for adjunctive aripiprazole-treated patients and 2% for adjunctive placebo-treated patients.

The commonly observed adverse reactions associated with the use of adjunctive aripiprazole tablets in patients with major depressive disorder (incidence of 5% or greater and aripiprazole tablets incidence at least twice that for placebo) were: akathisia, restlessness, insomnia, constipation, fatigue, and blurred vision.

Table 4 enumerates the pooled incidence, rounded to the nearest percent, of adverse reactions that occurred during acute therapy (up to 6 weeks), including only those adverse reactions that occurred in 2% or more of patients treated with adjunctive aripiprazole tablets (doses ≥2 mg/day) and for which the incidence in patients treated with adjunctive aripiprazole tablets was greater than the incidence in patients treated with adjunctive placebo in the combined dataset.

Dose-Related Adverse Reactions In Patients With Schizophrenia

Dose response relationships for the incidence of treatment-emergent adverse events were evaluated from four trials in adult patients with schizophrenia comparing various fixed doses (2, 5, 10, 15, 20, and 30 mg/day) of oral aripiprazole to placebo. 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%).

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.

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 tablets and placebo, with the exception of the Barnes Akathisia Scale (aripiprazole tablets, 0.08; placebo, –0.05).

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 tablets and placebo.

Bipolar Mania

In the short-term, placebo-controlled trials in bipolar mania in adults, the incidence of reported EPSrelated events, excluding events related to akathisia, for monotherapy aripiprazole-treated patients was 16% vs. 8% for placebo and the incidence of akathisia-related events for monotherapy aripiprazoletreated patients was 13% vs. 4% for placebo. In the 6 week, placebo-controlled trial in bipolar mania for adjunctive therapy with lithium or valproate, the incidence of reported EPS-related events, excluding events related to akathisia for adjunctive aripiprazole-treated patients was 15% vs. 8% for adjunctive placebo and the incidence of akathisia-related events for adjunctive aripiprazole-treated patients was 19% vs. 5% for adjunctive placebo.

In the adult bipolar mania trials with monotherapy aripiprazole tablets, the Simpson Angus Rating Scale and the Barnes Akathisia Scale showed a significant difference between aripiprazole tablets and placebo (aripiprazole tablets, 0.50; placebo, –0.01 and aripiprazole tablets, 0.21; placebo, –0.05). Changes in the Assessments of Involuntary Movement Scales were similar for the aripiprazole tablets and placebo groups. In the bipolar mania trials with aripiprazole tablets as adjunctive therapy with either lithium or valproate, the Simpson Angus Rating Scale and the Barnes Akathisia Scale showed a significant difference between adjunctive aripiprazole tablets and adjunctive placebo (aripiprazole tablets, 0.73; placebo, 0.07 and aripiprazole tablets, 0.30; placebo, 0.11). Changes in the Assessments of Involuntary Movement Scales were similar for adjunctive aripiprazole tablets and adjunctive placebo.

Major Depressive Disorder

In the short-term, placebo-controlled trials in major depressive disorder, the incidence of reported EPS-related events, excluding events related to akathisia, for adjunctive aripiprazole-treated patients was 8% vs. 5% for adjunctive placebo-treated patients; and the incidence of akathisia-related events for adjunctive aripiprazole-treated patients was 25% vs. 4% for adjunctive placebo-treated patients.

In the major depressive disorder trials, the Simpson Angus Rating Scale and the Barnes Akathisia Scale showed a significant difference between adjunctive aripiprazole tablets and adjunctive placebo (aripiprazole tablets, 0.31; placebo, 0.03 and aripiprazole tablets, 0.22; placebo, 0.02). Changes in the Assessments of Involuntary Movement Scales were similar for the adjunctive aripiprazole tablets and adjunctive placebo groups.

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.

Skin Irritation For MYCITE Patch

Symptoms of skin irritation localized at the site of the MYCITE Patch may occur in some patients. In clinical studies, sixty-one patients (12.4%) experienced skin rashes localized at the site of patch placement.

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 tablets 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 led to discontinuation (<1%) of aripiprazole tablets. In addition, in a long-term (52 week), active-controlled study, the incidence of tremor was 5% (40/859) for aripiprazole tablets. A similar profile was observed in a long-term monotherapy study and a long-term adjunctive study with lithium and valproate in bipolar disorder.

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), pathological gambling, hiccups and blood glucose fluctuation.
