  • The CGI-I scale allows the clinician to assess and rate improvement in schizophrenia on a scale of 1 (very much improved) to 7 (very much worse) based on the change in clinical condition from baseline1
  • In an exploratory analysis,* improvement in CGI-I was seen for both ARISTADA groups vs the placebo group at each post-baseline visit5

*Exploratory analysis: Analysis of all exploratory endpoints was supportive of the prespecified key primary and secondary endpoints. However, these analyses do not allow definitive efficacy conclusions regarding treatment effects of ARISTADA to be drawn.

  • In a post hoc analysis† of the 12-week phase 3 clinical trial, improvement was seen in a subgroup of patients with more severe symptoms. Patients with PANSS total score >92 at baseline showed a mean reduction in PANSS total score from baseline to day 85. Those receiving placebo (n=99), ARISTADA 441 mg monthly (n=95), and ARISTADA 882 mg monthly (n=100) experienced a mean decrease in PANSS total scores of 7.44, 22.14, and 24.05, respectively6

Post hoc analysis: The 12-week phase 3 study was not designed to prospectively assess, nor was it adequately powered to examine, the efficacy of ARISTADA in the treatment of this subgroup of patients. Therefore, there are limitations to these data, and no conclusions can be drawn from this post hoc analysis.

Efficacy of the 2-month Dose

The efficacy of ARISTADA 441 mg monthly and 882 mg monthly was established in the phase 3 clinical trial. The efficacy of ARISTADA 662 mg monthly, 882 mg every 6 weeks, and 1064 mg every 2 months was established by pharmacokinetic bridging, which demonstrated that these dosing regimens resulted in plasma aripiprazole concentrations that are within the range provided by doses of 441 mg monthly and 882 mg monthly.1

Safety and tolerability

ARISTADA has been evaluated for safety in 1180 adult patients in clinical trials in schizophrenia1

  • In an open-label pharmacokinetic study, adverse reactions associated with the use of ARISTADA® were similar across the 441 mg monthly, 882 every 6 weeks, and 1064 mg every 2 months groups1

Discontinuations

  • In the 12-week clinical trial, discontinuations due to adverse events in patients receiving ARISTADA were lower than for placebo: 6.8% for the 441 mg dose, 2.9% for the 882 mg dose, and 17.9% for placebo2
  • In the placebo group, the majority of adverse events leading to discontinuation were related to exacerbation of psychosis/schizophrenia. Otherwise, adverse events leading to discontinuation were similar between the 3 treatment groups2,5

  • In the 12-week clinical trial, mean prolactin levels decreased below baseline measurements starting at Day 29 through Day 85 in both ARISTADA groups compared with placebo7
  • Baseline prolactin levels may have been affected by previous antipsychotic medication use prior to starting the study2
  • Patients in the clinical trial had previously established tolerability to aripiprazole, which may affect prolactin measurements2

  • The percentage of patients with ≥7% increase in weight noted at the last post-baseline visit during the treatment period was 6% for placebo, 10% for ARISTADA 441 mg monthly, and 9% for ARISTADA 882 mg monthly1

Injection site reactions

  • In the phase 3 clinical trial, overall injection-site reactions were reported in 2% (placebo), 4% (441 mg monthly), and 5% (882 mg monthly) of patients1
    • Of these, the incidence of pain was 2%, 3%, and 4%, respectively, and ≤1% with each subsequent injection. Other injection-site reactions (induration, swelling, and redness) were reported in <1% of patients1
  • In an open-label pharmacokinetic study evaluating 441 mg monthly, 882 mg every 6 weeks, and 1064 mg every 2 months, injection-site reactions were similar across the dose groups1

Safety of ARISTADA INITIO®

  • In pharmacokinetic studies, the safety profile of ARISTADA INITIO® (aripiprazole lauroxil) was generally consistent with that observed for ARISTADA8
  • The most commonly observed adverse reaction was akathisia in the 12-week clinical trial for ARISTADA1,8
  • In pharmacokinetic studies evaluating ARISTADA INITIO, the incidences of injection-site reactions with ARISTADA INITIO were similar to the incidence observed for ARISTADA8
  • A phase 1 study evaluating the safety, tolerability, and pharmacokinetics of the 2 initiation regimens was conducted (N=161). In this study, patients received 21 days of oral aripiprazole (15 mg daily dose) and one ARISTADA dose (n=81) or one injection of ARISTADA INITIO plus a single dose of 30 mg oral aripiprazole and one ARISTADA dose (n=80). Patients were randomized 1:1:1:1 to receive an ARISTADA dose of either 441 mg or 882 mg9
    • There were 2 cases of akathisia in the 21-day oral aripiprazole arms (2 mild cases)
    • There were 4 cases of akathisia in the ARISTADA INITIO arms (3 mild cases, 1 moderate case)
    • None of the patients experienced serious adverse events or discontinued participation in the trial due to akathisia

SCROLL FOR IMPORTANT SAFETY INFORMATION

IMPORTANT SAFETY INFORMATION

BOXED 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 of death. ARISTADA INITIO and ARISTADA are 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 Reactions, Including Stroke: Increased incidence of cerebrovascular adverse reactions (e.g., stroke, transient ischemic attack), including fatalities, have been reported in placebo-controlled trials of elderly patients with dementia-related psychosis treated with risperidone, aripiprazole, and olanzapine. ARISTADA INITIO and ARISTADA are not approved for the treatment of patients with dementia-related psychosis.

Potential for Dosing and Medication Errors: Medication errors, including substitution and dispensing errors, between ARISTADA INITIO and ARISTADA could occur. ARISTADA INITIO is intended for single administration in contrast to ARISTADA which is administered monthly, every 6 weeks, or every 8 weeks. Do not substitute ARISTADA INITIO for ARISTADA because of differing pharmacokinetic profiles.

Neuroleptic Malignant Syndrome (NMS): A potentially fatal symptom complex may occur with administration of antipsychotic drugs, including ARISTADA INITIO and ARISTADA. Clinical manifestations of NMS include hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (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 antipsychotics should be consistent with the need to minimize TD. Discontinue ARISTADA if clinically appropriate. TD 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. There have been reports of hyperglycemia in patients treated with oral 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 require continuation of antidiabetic 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: Compulsive or uncontrollable urges to gamble have been reported with use of aripiprazole. Other compulsive urges less frequently reported include sexual urges, shopping, binge eating and other impulsive or compulsive behaviors which may result in harm for the patient and others if not recognized. Closely monitor patients and consider dose reduction or stopping aripiprazole if a patient develops such urges.

Orthostatic Hypotension: Aripiprazole may cause orthostatic hypotension which can be associated with dizziness, lightheadedness, and tachycardia. Monitor heart rate and blood pressure, and warn patients with known cardiovascular or cerebrovascular disease and risk of dehydration and syncope.

Falls: Antipsychotics including ARISTADA INITIO and ARISTADA may cause somnolence, postural hypotension or motor and sensory instability which may lead to falls and subsequent injury. Upon initiating treatment and recurrently, complete fall risk assessments as appropriate.

Leukopenia, Neutropenia, and Agranulocytosis: Leukopenia, neutropenia and agranulocytosis have been reported with antipsychotics. Monitor complete blood count in patients with pre-existing low white blood cell count (WBC)/absolute neutrophil count or history of drug-induced leukopenia/neutropenia. Discontinue ARISTADA INITIO and/or ARISTADA at the first sign of a clinically significant decline in WBC and in severely neutropenic patients.

Seizures: Use with caution in patients with a history of seizures or with conditions that lower the seizure threshold.

Potential for Cognitive and Motor Impairment: ARISTADA INITIO and ARISTADA may impair judgment, thinking, or motor skills. Patients should be cautioned about operating hazardous machinery, including automobiles, until they are certain therapy with ARISTADA INITIO and/or ARISTADA 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 antipsychotic drug use; use caution in patients at risk for aspiration pneumonia.

Concomitant Medication: ARISTADA INITIO is only available at a single strength as a single-dose pre-filled syringe, so dosage adjustments are not possible. Avoid use in patients who are known CYP2D6 poor metabolizers or taking strong CYP3A4 inhibitors, strong CYP2D6 inhibitors, or strong CYP3A4 inducers, antihypertensive drugs or benzodiazepines.

Depending on the ARISTADA dose, adjustments may be recommended if patients are 1) known as CYP2D6 poor metabolizers and/or 2) taking strong CYP3A4 inhibitors, strong CYP2D6 inhibitors, or strong CYP3A4 inducers for greater than 2 weeks. Avoid use of ARISTADA 662 mg, 882 mg, or 1064 mg for patients taking both strong CYP3A4 inhibitors and strong CYP2D6 inhibitors. (See Table 4 in the ARISTADA full Prescribing Information.)

Commonly Observed Adverse Reactions: In pharmacokinetic studies the safety profile of ARISTADA INITIO was generally consistent with that observed for ARISTADA. The most common adverse reaction (≥5% incidence and at least twice the rate of placebo reported by patients treated with ARISTADA 441 mg and 882 mg monthly) was akathisia.

Injection Site Reactions: In pharmacokinetic studies evaluating ARISTADA INITIO, the incidences of injection site reactions with ARISTADA INITIO were similar to the incidence observed with ARISTADA. Injection site reactions were reported by 4%, 5%, and 2% of patients treated with 441 mg ARISTADA (monthly), 882 mg ARISTADA (monthly), and placebo, respectively. Most of these were injection site pain and associated with the first injection and decreased with each subsequent injection. Other injection site reactions (induration, swelling, and redness) occurred at less than 1%.

Dystonia: Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first days of treatment and at low doses.

Pregnancy/Nursing: May cause extrapyramidal and/or withdrawal symptoms in neonates with third trimester exposure. Advise patients to notify their healthcare provider of a known or suspected pregnancy. Inform patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ARISTADA INITIO and/or ARISTADA during pregnancy. Aripiprazole is present in human breast milk. The benefits of breastfeeding should be considered along with the mother’s clinical need for ARISTADA INITIO and/or ARISTADA and any potential adverse effects on the infant from ARISTADA INITIO and/or ARISTADA or from the underlying maternal condition.
