PRINCETON, N.J. & DEERFIELD, Ill.

Otsuka Pharmaceutical Development & Commercialization, Inc. (Otsuka) and Lundbeck presented data on aripiprazole for extended-release injectable suspension for intramuscular use (hereinafter ABILIFY MAINTENA®) in the maintenance treatment of bipolar I disorder (BP-I) at the 2016 Annual Meeting of the American College of Neuropsychopharmacology (ACNP) in Hollywood, Florida.

Study data demonstrate that ABILIFY MAINTENA delayed time to recurrence of mood episodes in adult patients1. Treatment was compared with placebo and demonstrated a safety profile consistent with that observed with ABILIFY MAINTENA in the treatment of patients with schizophrenia.

“Patients with bipolar I disorder can benefit from a long acting injectable, which may help provide longer term stability in patients who have difficulty in taking a daily pill,” said Joseph Calabrese, M.D., Director of Mood Disorders Program at University Hospitals Cleveland Medical Center, and professor of psychiatry at Case Western Reserve University School of Medicine.

Study results

Results were from a 52-week, phase III, double-blind, randomized withdrawal trial in adults with BP-I aged 18 to 65 years.1 The primary endpoint demonstrated ABILIFY MAINTENA significantly delayed time to recurrence of any mood episode (see recurrence criteria below) during a 52-week treatment study compared with placebo (Hazard Ratio: 0.451; 95 percent Confidence Interval: [0.299-0.678]; p<0.0001).1 The key secondary endpoint, the proportion of patients with recurrence of any mood episode in the randomized phase, was significantly lower (p<0.0001) in the ABILIFY MAINTENA group (35/132; 26.5 percent) compared to the placebo group (68/133; 51.1 percent); results were driven primarily by reductions in manic recurrences.1

The study also demonstrated a statistically significant improvement vs. placebo on the Clinical Global Impression – Bipolar Version – Severity (CGI-BP-S) Mania Score (p=0.0011) and a time to hospitalization that was significantly delayed in participants randomized to ABILIFY MAINTENA vs. placebo (p=0.0002; secondary endpoints, see below).1 Serious adverse events in the randomized phase were reported by 10/132 (7.6 percent) patients in the ABILIFY MAINTENA group vs. 25/133 (18.8 percent) patients in the placebo group. Treatment emergent adverse events (TEAEs) in the randomized phase were 101/132 (76.5 percent) on ABILIFY MAINTENA and 107/133 (80.5 percent) on placebo.1

About the Study

Patients in the “Efficacy and Safety of Aripiprazole Once-Monthly in the Maintenance Treatment of Bipolar I Disorder: A Double-Blind, Placebo-Controlled, Randomized Withdrawal Study” were required to be experiencing a manic episode (per DSM-IV-TR criteria) with a Young-Mania Rating Scale (YMRS) total score ≥20 at study entry, as well as at least one previous manic or mixed episode requiring hospitalization or treatment with a mood stabilizer or antipsychotic agent.1 The study was composed of multiple phases: following screening for eligibility, subjects entered a conversion phase to oral aripiprazole monotherapy, if needed, followed by an oral aripiprazole stabilization phase, a single-blind ABILIFY MAINTENA stabilization phase, and, a double-blind, placebo-controlled randomized withdrawal phase. The primary endpoint was the time from randomization to recurrence of any mood episode defined by any of the following criteria: hospitalization for any mood episode, YMRS total score ≥15, Montgomery Asberg Depression Rating Scale total score ≥15, Clinical Global Impression – Bipolar Version-Severity (CGI-BP-S) score >4, serious treatment-emergent adverse event (TEAE) of disease worsening, discontinuation due to lack of efficacy/disease worsening, clinical worsening with need for pharmacological treatment of symptoms, or active suicidality.1

The proportion of patients with recurrence of any mood episode was the key secondary endpoint.1 Other secondary endpoints included: 1) adjusted mean change from baseline to week 52 in CGI-BP-S mania scores was significantly better with ABILIFY MAINTENA vs. placebo (least squares mean difference: –0.43; 95% CI [–0.69 to –0.17]; P=0.0011); and 2) time to recurrence as defined by hospitalization for a mood disorder was delayed with ABILIFY MAINTENA vs. placebo (Hazard Ratio: 0.137; 95 percent Confidence Interval: [0.040-0.465]; p=0.0002).1

ABILIFY MAINTENA exhibited a tolerability profile in patients with bipolar I disorder similar to that in treatment of patients with schizophrenia. During the ABILIFY MAINTENA stabilization phase, the TEAEs (≥ 5 percent) were akathisia (17.4 percent), weight increased (11.1 percent), insomnia (9.6 percent), anxiety (7.1 percent), restlessness (5.6 percent), fatigue (5.2 percent) and nasopharyngitis (5.2 percent).1 In the randomized phase, specific TEAEs reported by greater than or equal to 5 percent of patients and greater in the ABILIFY MAINTENA group than in the placebo group respectively, were increased weight (23.5 percent vs. 18.0 percent), akathisia (21.2 percent vs. 12.8 percent), insomnia (7.6 percent vs. 7.5 percent) and anxiety (6.8 percent vs. 4.5 percent).1

About ABILIFY MAINTENA® (long-acting injectable aripiprazole)

ABILIFY MAINTENA is an extended-release injectable suspension, for intramuscular use developed by Otsuka in Japan and is co-commercialized by the alliance between Otsuka and H. Lundbeck. ABILIFY MAINTENA was approved in the U.S. in 2013 for the treatment of adults with schizophrenia.2 Efficacy and safety for ABILIFY MAINTENA is supported by a short-term (12-week), randomized, double-blind, placebo-controlled trial in acutely relapsed adults, as well as a longer term (52-week) placebo-controlled, double-blind, randomized-withdrawal study for the maintenance treatment of schizophrenia.3

ABILIFY MAINTENA, an atypical antipsychotic, is an intramuscular depot formulation of aripiprazole.3 It is a sterile lyophilized powder that, when reconstituted with sterile water for injection, forms an injectable suspension that can be administered monthly.3 After an initial injection of ABILIFY MAINTENA along with an overlapping 14-day dosing of oral antipsychotic treatment, subsequent injections of ABILIFY MAINTENA provide uninterrupted medication coverage for 30 days at a time.3 It provides a treatment option to address two of the most important considerations in the management of schizophrenia — improving symptoms in patients with an acute relapse of their disease and reducing the risk of relapse or the re-emergence of worsening of symptoms.3 Depot formulations of antipsychotic agents provide patients with concentrations of active drug that remain at a therapeutic range for an extended period of time.4,5

About Bipolar I Disorder

Bipolar I disorder is a chronic mental illness.6 People with bipolar I disorder experience one or more episodes of mania, and may have episodes of both mania and depression; however, an episode of depression is not necessary for a bipolar I disorder diagnosis.6 The lifetime prevalence estimate of bipolar I disorder in the U.S. is 1.0 percent and 12-month prevalence is 0.6 percent.7 If left untreated, the manic and depressive symptoms may get worse.6

INDICATION and IMPORTANT SAFETY INFORMATION for ABILIFY MAINTENA® (aripiprazole)

INDICATION

ABILIFY MAINTENA is an atypical antipsychotic indicated for the treatment of schizophrenia.

IMPORTANT SAFETY INFORMATION

WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS

Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk (1.6 to 1.7 times) of death compared to placebo (4.5% vs 2.6%, respectively). Although the causes of death were varied, most of the deaths appeared to be cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. ABILIFY MAINTENA is not approved for the treatment of patients with dementia-related psychosis.

Contraindication: Known hypersensitivity reaction to aripiprazole. Reactions have ranged from pruritus/urticaria to anaphylaxis.

Cerebrovascular Adverse Events, Including Stroke: Increased incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, have been reported in clinical trials of elderly patients with dementia-related psychosis treated with oral aripiprazole.

Neuroleptic Malignant Syndrome (NMS): A potentially fatal symptom complex sometimes referred to as NMS may occur with administration of antipsychotic drugs, including ABILIFY MAINTENA. Rare cases of NMS occurred during aripiprazole treatment. Signs and symptoms of NMS include hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (e.g., irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia). Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure. The management of NMS should include: 1) immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy; 2) intensive symptomatic treatment and medical monitoring; and 3) treatment of any concomitant serious medical problems for which specific treatments are available.

Tardive Dyskinesia (TD): The risk of developing TD (a syndrome of abnormal, involuntary movements) and the potential for it to become irreversible are believed to increase as the duration of treatment and the total cumulative dose of antipsychotic increase. The syndrome can develop, although much less commonly, after relatively brief treatment periods at low doses. Prescribing should be consistent with the need to minimize TD. There is no known treatment for established TD, although the syndrome may remit, partially or completely, if antipsychotic treatment is withdrawn.

Metabolic Changes: Atypical antipsychotic drugs have been associated with metabolic changes that include:

  • Hyperglycemia/Diabetes Mellitus: Hyperglycemia, in some cases extreme and associated with ketoacidosis, coma, or death, has been reported in patients treated with atypical antipsychotics including aripiprazole. Patients with diabetes should be regularly monitored for worsening of glucose control; those with risk factors for diabetes should undergo baseline and periodic fasting blood glucose testing. Any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Patients who develop symptoms of hyperglycemia should also undergo fasting blood glucose testing. In some cases, hyperglycemia has resolved when the atypical antipsychotic was discontinued; however, some patients required continuation of anti-diabetic treatment despite discontinuation of the suspect drug.
  • Dyslipidemia: Undesirable alterations in lipids have been observed in patients treated with atypical antipsychotics.
  • Weight Gain: Weight gain has been observed with atypical antipsychotic use. Clinical monitoring of weight is recommended.

Pathological Gambling and Other Compulsive Behaviors: Intense urges, particularly for gambling, and the inability to control these urges have been reported while taking aripiprazole. Other compulsive urges (e.g., eating, sexual, or shopping) have been reported less frequently. Prescribers should ask patients or their caregivers specifically about, and closely monitor for, the development of new or intense compulsive urges. Consider dose reduction or stopping aripiprazole, if such urges develop.

Orthostatic Hypotension: ABILIFY MAINTENA may cause orthostatic hypotension and should be used with caution in patients with known cardiovascular disease, cerebrovascular disease, or conditions which would predispose them to hypotension.

Leukopenia, Neutropenia, and Agranulocytosis: Leukopenia, neutropenia, and agranulocytosis have been reported. In patients with a history of clinically significant low white blood cell count (WBC)/absolute neutrophil count (ANC) or history of drug-induced leukopenia/neutropenia, perform a complete blood count (CBC) frequently during the first few months of therapy. Consider discontinuing ABILIFY MAINTENA at the first sign of a clinically significant decline in WBC in the absence of other causative factors. Monitor patients with clinically significant neutropenia for fever or other symptoms or signs of infection and treat promptly if such symptoms or signs occur. Discontinue ABILIFY MAINTENA in patients with severe neutropenia (ANC <1000/mm3) and follow their WBC counts until recovery.

Seizures: ABILIFY MAINTENA should be used with caution in patients with a history of seizures or with conditions that lower the seizure threshold.

Potential for Cognitive and Motor Impairment: ABILIFY MAINTENA may impair judgment, thinking, or motor skills. Instruct patients to avoid operating hazardous machinery, including automobiles, until they are certain ABILIFY MAINTENA does not affect them adversely.

Body Temperature Regulation: Disruption of the body’s ability to reduce core body temperature has been attributed to antipsychotic agents. Advise patients regarding appropriate care in avoiding overheating and dehydration. Appropriate care is advised for patients who may exercise strenuously, may be exposed to extreme heat, receive concomitant medication with anticholinergic activity, or are subject to dehydration.

Dysphagia: Esophageal dysmotility and aspiration have been associated with ABILIFY MAINTENA; use caution in patients at risk for aspiration pneumonia.

Alcohol: Advise patients to avoid alcohol while taking ABILIFY MAINTENA.

Concomitant Medication: Dosage adjustments are recommended in patients who are CYP2D6 poor metabolizers and in patients taking concomitant CYP3A4 inhibitors or CYP2D6 inhibitors for greater than 14 days. If the CYP3A4 inhibitor or CYP2D6 inhibitor is withdrawn, the ABILIFY MAINTENA dosage may need to be increased. Avoid the concomitant use of CYP3A4 inducers with ABILIFY MAINTENA for greater than 14 days because the blood levels of aripiprazole are decreased and may be below the effective levels. Dosage adjustments are not recommended for patients with concomitant use of CYP3A4 inhibitors, CYP2D6 inhibitors or CYP3A4 inducers for less than 14 days.

Most Commonly Observed Adverse Reactions: Based on the placebo-controlled trial of ABILIFY MAINTENA in schizophrenia, the most commonly observed adverse reactions associated with the use of ABILIFY MAINTENA (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%).

Injection Site Reactions: 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. 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.

Dystonia: Symptoms of dystonia may occur in susceptible individuals during the first days of treatment and at low doses.

Pregnancy: Neonates exposed to antipsychotic drugs, including ABILIFY MAINTENA, during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms. These complications have varied in severity, from being self-limited to requiring intensive care and prolonged hospitalization. ABILIFY MAINTENA should be used during pregnancy only if the potential benefits justify the potential risks to the fetus.

Lactation: Aripiprazole is present in human breast milk. A decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother and any potential risks to the infant.
