6.1 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. Safety Database of ABILIFY MAINTENA and Oral Aripiprazole Oral aripiprazole has been evaluated for safety in 16,114 adult patients who participated in multiple-dose, clinical trials in schizophrenia and other indications, and who had approximately 8,578 patient-years of exposure to oral aripiprazole. A total of 3,901 patients were treated with oral aripiprazole for at least 180 days, 2,259 patients were treated with oral aripiprazole for at least 360 days, and 933 patients continuing aripiprazole treatment for at least 720 days. ABILIFY MAINTENA has been evaluated for safety in 2,128 adult patients in clinical trials in schizophrenia, with approximately 2,633 patient-years of exposure to ABILIFY MAINTENA. A total of 1,229 patients were treated with ABILIFY MAINTENA for at least 180 days (at least 7 consecutive injections) and 935 patients treated with ABILIFY MAINTENA had at least 1 year of exposure (at least 13 consecutive injections). ABILIFY MAINTENA has been evaluated for safety in 804 adult patients in clinical trials in bipolar I disorder, with approximately 530 patient-years of exposure to ABILIFY MAINTENA. A total of 419 patients were treated with ABILIFY MAINTENA for at least 180 days (at least 7 consecutive injections) and 287 patients treated with ABILIFY MAINTENA had at least 1 year of exposure (at least 13 consecutive injections). The conditions and duration of treatment with ABILIFY MAINTENA included double-blind and open-label studies. The safety data presented below are derived from the 12-week double-blind placebo-controlled study of ABILIFY MAINTENA in adult patients with schizophrenia. Adverse Reactions with ABILIFY MAINTENA Most Commonly Observed Adverse Reactions in Double-Blind, Placebo-Controlled Clinical Trials in Schizophrenia Based on the placebo-controlled trial of ABILIFY MAINTENA in schizophrenia, the most commonly observed adverse reactions associated with the use of ABILIFY MAINTENA in patients (incidence of 5% or greater and aripiprazole incidence at least twice that for placebo) were increased weight (16.8% vs. 7.0%), akathisia (11.4% vs. 3.5%), injection site pain (5.4% vs. 0.6%) and sedation (5.4% vs. 1.2%). Commonly Reported Adverse Reactions in Double-Blind, Placebo-Controlled Clinical Trials in Schizophrenia The following findings are based on the double-blind, placebo-controlled trial that compared ABILIFY MAINTENA 400 mg or 300 mg to placebo in patients with schizophrenia. Table 8 lists the adverse reactions reported in 2% or more of ABILIFY MAINTENA-treated subjects and at a greater proportion than in the placebo group.

Reactions are categorized by body system according to the following definitions: frequent adverse reactions are those occurring in at least 1/100 patients; infrequent adverse reactions are those occurring in 1/100 to 1/1000 patients; rare reactions are those occurring in fewer than 1/1000 patients: Blood and Lymphatic System Disorders: rare - thrombocytopenia Cardiac Disorders: infrequent - tachycardia; rare - bradycardia, sinus tachycardia Endocrine Disorders: rare - hypoprolactinemia Eye Disorders: infrequent - vision blurred, oculogyric crisis Gastrointestinal Disorders: infrequent - abdominal pain upper, dyspepsia, nausea; rare -swollen tongue General Disorders and Administration Site Conditions: frequent - fatigue, injection site reactions (including erythema, induration, pruritus, injection site reaction, swelling, rash, inflammation, hemorrhage); infrequent - chest discomfort, gait disturbance; rare -irritability, pyrexia Hepatobiliary Disorders: rare - drug induced liver injury Immune System Disorders: rare - drug hypersensitivity Infections and Infestations: rare - nasopharyngitis Investigations: infrequent - blood creatine phosphokinase increased, blood pressure decreased, hepatic enzyme increased, liver function test abnormal, electrocardiogram QT-prolonged; rare - blood triglycerides decreased, blood cholesterol decreased, electrocardiogram T-wave abnormal Metabolism and Nutrition Disorders: infrequent - decreased appetite, obesity, hyperinsulinemia Musculoskeletal and Connective Tissue Disorders: infrequent - joint stiffness, muscle twitching, trismus; rare - rhabdomyolysis Nervous System Disorders: infrequent - extrapyramidal disorder, hypersomnia, lethargy; rare - bradykinesia, convulsion, dysgeusia, memory impairment, oromandibular dystonia Psychiatric Disorders: frequent - anxiety, insomnia, restlessness; infrequent - agitation, bruxism, psychotic disorder, suicidal ideation; rare - aggression, hypersexuality, panic attack Renal and Urinary Disorders: rare - glycosuria, pollakiuria, urinary incontinence Reproductive System and Breast Disorders: infrequent - ejaculation delayed Vascular Disorders: infrequent - hypertension Demographic Differences An examination of population subgroups was performed across demographic subgroup categories for adverse reactions experienced by at least 5% of ABILIFY MAINTENA subjects at least twice rate of the placebo (i.e., increased weight, akathisia, injection site pain, and sedation) in the double-blind placebo-controlled trial. This analysis did not reveal evidence of differences in safety differential adverse reaction incidence on the basis of age, gender, or race alone; however, there were few subjects ≥65 years of age. Injection Site Reactions of ABILIFY MAINTENA In the data from the short-term, double-blind, placebo-controlled trial with ABILIFY MAINTENA in patients with schizophrenia, the percent of patients reporting any injection site-related adverse reaction (all reported as injection site pain) was 5.4% for patients treated with gluteal administered ABILIFY MAINTENA and 0.6% for placebo. The mean intensity of injection pain reported by subjects using a visual analog scale (0=no pain to 100=unbearably painful) approximately one hour after injection was 7.1 (SD 14.5) for the first injection and 4.8 (SD 12.4) at the last visit in the double-blind, placebo-controlled phase. In an open-label study comparing bioavailability of ABILIFY MAINTENA administered in the deltoid or gluteal muscle, injection site pain was observed in both groups at approximately equal rates. Extrapyramidal Symptoms (EPS) In the short-term, placebo-controlled trial of ABILIFY MAINTENA in adults with schizophrenia, the incidence of reported EPS-related events, excluding events related to akathisia, for ABILIFY MAINTENA-treated patients was 9.6% vs. 5.2% for placebo. The incidence of akathisia-related events for ABILIFY MAINTENA-treated patients was 11.5% vs. 3.5% for 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. In the short-term, placebo-controlled trial of ABILIFY MAINTENA in adults with schizophrenia, the incidence of dystonia was 1.8% for ABILIFY MAINTENA vs. 0.6% for placebo. Neutropenia In the short-term, placebo-controlled trial of ABILIFY MAINTENA in adults with schizophrenia, the incidence of neutropenia (absolute neutrophil count ≤1.5 thous/mcL) for ABILIFY MAINTENA-treated patients was 5.7% vs. 2.1% for placebo. An absolute neutrophil count of <1 thous/mcL (i.e., 0.95 thous/mcL) was observed in only one patient on ABILIFY MAINTENA and resolved spontaneously without any associated adverse events.

6.2 Postmarketing

Experience The following adverse reactions have been identified during post-approval use of oral aripiprazole or ABILIFY MAINTENA. 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, blood glucose fluctuation, drug reaction with eosinophilia and systemic symptoms (DRESS), and fecal incontinence.
