INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS
See full prescribing information for complete Boxed Warning.
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Cariprazine is not approved for the treatment of patients with dementia-related psychosis
|
Overview
Cariprazine is an atypical antipsychotic that is FDA approved for the treatment of patients with schizophrenia and acute treatment of manic or mixed episodes associated with bipolar I disorder. There is a Black Box Warning for this drug as shown here. Common adverse reactions include extrapyramidal symptoms and akathisia in Schizophrenia patients and extrapyramidal symptoms, akathisia, dyspepsia, vomiting, somnolence, and restlessness in patients with Bipolar mania (≥5%).
Adult Indications and Dosage
FDA-Labeled Indications and Dosage (Adult)
Indications
Cariprazine is indicated for the:
- Treatment of schizophrenia
- Acute treatment of manic or mixed episodes associated with bipolar I disorder
Dosage
Cariprazine is given orally once daily and can be taken with or without food.
Because of the long half-life of Cariprazine and its active metabolites, changes in dose will not be fully reflected in plasma for several weeks. Prescribers should monitor patients for adverse reactions and treatment response for several weeks after starting Cariprazine and after each dosage change.
The maximum recommended dose is 6 mg daily. In short-term controlled trials, dosages above 6 mg daily do not confer increased effectiveness sufficient to outweigh dose-related adverse reactions.
The recommended dose range is 1.5 mg to 6 mg once daily. The starting dose of Cariprazine is 1.5 mg. The dosage can be increased to 3 mg on Day 2. Depending upon clinical response and tolerability, further dose adjustments can be made in 1.5 mg or 3 mg increments.
- Manic or Mixed Episodes Associated with Bipolar I Disorder
The recommended dose range is 3 mg to 6 mg once daily. The starting dose of Cariprazine is 1.5 mg and should be increased to 3 mg on Day 2. Depending upon clinical response and tolerability, further dose adjustments can be made in 1.5 mg or 3 mg increments.
- Dosage Adjustments for CYP3A4 Inhibitors and Inducers
CYP3A4 is responsible for the formation and elimination of the major active metabolites of Cariprazine.
- Dosage recommendation for patients initiating a strong CYP3A4 inhibitor while on a stable dose of Cariprazine: If a strong CYP3A4 inhibitor is initiated, reduce the current dosage of Cariprazine by half. For patients taking 4.5 mg daily, the dosage should be reduced to 1.5 mg or 3 mg daily. For patients taking 1.5 mg daily, the dosing regimen should be adjusted to every other day. When the CYP3A4 inhibitor is withdrawn, Cariprazine dosage may need to be increased.
- Dosage recommendation for patients initiating Cariprazine therapy while already on a strong CYP3A4 inhibitor: Patients should be administered 1.5 mg of Cariprazine on Day 1 and on Day 3 with no dose administered on Day 2. From Day 4 onward, the dose should be administered at 1.5 mg daily, then increased to a maximum dose of 3 mg daily. When the CYP3A4 inhibitor is withdrawn, Cariprazine dosage may need to be increased.
- Dosage recommendation for patients concomitantly taking Cariprazine with CYP3A4 inducers:Concomitant use of Cariprazine and a CYP3A4 inducer has not been evaluated and is not recommended because the net effect on active drug and metabolites is unclear.
- Treatment Discontinuation
Following discontinuation of Cariprazine, the decline in plasma concentrations of active drug and metabolites may not be immediately reflected in patients' clinical symptoms; the plasma concentration of Cariprazine and its active metabolites will decline by 50% in ~1 week. There are no systematically collected data to specifically address switching patients from Cariprazine to other antipsychotics or concerning concomitant administration with other antipsychotics.

Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Cariprazine is not approved for the treatment of patients with dementia-related psychosis
|
Increased Mortality in Elderly Patients with Dementia-Related Psychosis
Antipsychotic drugs increase the all-cause risk of death in elderly patients with dementia-related psychosis. Analyses of 17 dementia-related psychosis placebo-controlled trials (modal duration of 10 weeks and largely in patients taking atypical antipsychotic drugs) revealed a risk of death in the drug-treated patients of between 1.6 to 1.7 times that in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in placebo-treated patients.
Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Cariprazine is not approved for the treatment of patients with dementia-related psychosis.
Cerebrovascular Adverse Reactions, Including Stroke, in Elderly Patients with Dementia-Related Psychosis
In placebo-controlled trials in elderly subjects with dementia, patients randomized to risperidone, aripiprazole, and olanzapine had a higher incidence of stroke and transient ischemic attack, including fatal stroke. Cariprazine is not approved for the treatment of patients with dementia-related psychosis.
Neuroleptic Malignant Syndrome (NMS)
Neuroleptic Malignant Syndrome (NMS), a potentially fatal symptom complex, has been reported in association with administration of antipsychotic drugs. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, delirium, and autonomic instability. Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure.
If NMS is suspected, immediately discontinue Cariprazine and provide intensive symptomatic treatment and monitoring.
Falls
Cariprazine may cause somnolence, postural hypotension, motor and sensory instability, which may lead to falls and, consequently, fractures or other injuries. For patients with diseases, conditions, or medications that could exacerbate these effects, complete fall risk assessments when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic therapy.
Tardive Dyskinesia
Tardive dyskinesia, a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements, may develop in patients treated with antipsychotic drugs, including Cariprazine. The risk appears to be highest among the elderly, especially elderly women, but it is not possible to predict which patients are likely to develop the syndrome. Whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown.
The risk of tardive dyskinesia and the likelihood that it will become irreversible increase with the duration of treatment and the cumulative dose. The syndrome can develop after a relatively brief treatment period, even at low doses. It may also occur after discontinuation of treatment.
There is no known treatment for tardive dyskinesia, although the syndrome may remit, partially or completely, if antipsychotic treatment is discontinued. Antipsychotic treatment itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome, possibly masking the underlying process. The effect that symptomatic suppression has upon the long-term course of tardive dyskinesia is unknown.
Given these considerations, Cariprazine should be prescribed in a manner most likely to reduce the risk of tardive dyskinesia. Chronic antipsychotic treatment should generally be reserved for patients: 1) who suffer from a chronic illness that is known to respond to antipsychotic drugs; and 2) for whom alternative, effective, but potentially less harmful treatments are not available or appropriate. In patients who do require chronic treatment, use the lowest dose and the shortest duration of treatment producing a satisfactory clinical response should be sought. Periodically reassess the need for continued treatment.
If signs and symptoms of tardive dyskinesia appear in a patient on Cariprazine, drug discontinuation should be considered. However, some patients may require treatment with Cariprazine despite the presence of the syndrome.
Late-Occurring Adverse Reactions
Adverse events may first appear several weeks after the initiation of Cariprazine treatment, probably because plasma levels of Cariprazine and its major metabolites accumulate over time. As a result, the incidence of adverse reactions in short-term trials may not reflect the rates after longer term exposures.
Monitor for adverse reactions, including EPS or akathisia, and patient response for several weeks after a patient has begun Cariprazine and after each dosage increase. Consider reducing the dose or discontinuing the drug.
Metabolic Changes
Atypical antipsychotic drugs, including Cariprazine, have caused metabolic changes, including hyperglycemia, diabetes mellitus, dyslipidemia, and weight gain. Although all of the drugs in the class to date have been shown to produce some metabolic changes, each drug has its own specific risk profile.
Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics. Assess fasting plasma glucose before or soon after initiation of antipsychotic medication, and monitor periodically during long-term treatment.
In the 6-week, placebo-controlled trials of adult patients with schizophrenia, the proportion of patients with shifts in fasting glucose from normal (<100 mg/dL) to high (≥126 mg/dL) and borderline (≥100 and <126 mg/dL) to high were similar in patients treated with Cariprazine and placebo. In the long-term, open-label schizophrenia studies, 4% patients with normal hemoglobin A1c baseline values developed elevated levels ( ≥6.5%).
In the 3-week, placebo-controlled trials of adult patients with bipolar disorder, the proportion of patients with shifts in fasting glucose from normal (<100 mg/dL) to high (≥126 mg/dL) and borderline (≥100 and <126 mg/dL) to high were similar in patients treated with Cariprazine and placebo. In the long-term, open-label bipolar disorder studies, 4% patients with normal hemoglobin A1c baseline values developed elevated levels (≥6.5%).
Atypical antipsychotics cause adverse alterations in lipids. Before or soon after initiation of antipsychotic medication, obtain a fasting lipid profile at baseline and monitor periodically during treatment.
In the 6-week, placebo-controlled trials of adult patients with schizophrenia, the proportion of patients with shifts in fasting total cholesterol, LDL, HDL and triglycerides were similar in patients treated with Cariprazine and placebo.
In the 3-week, placebo-controlled trials of adult patients with bipolar disorder, the proportion of patients with shifts in fasting total cholesterol, LDL, HDL and triglycerides were similar in patients treated with Cariprazine and placebo.
- Weight Gain
Weight gain has been observed with use of atypical antipsychotics, including Cariprazine. Monitor weight at baseline and frequently thereafter. TABLES 1 and 2 show the change in body weight occurring from baseline to endpoint in 6-week schizophrenia and 3-week bipolar mania trials.
- Table 1. Change in Body Weight (kg) in 6-Week Schizophrenia Trials
VRAYLAR: Cariprazine's Brand name
- Table 2. Change in Body Weight (kg) in 3-Week Bipolar Mania Trials
VRAYLAR: Cariprazine's Brand name
In long-term, uncontrolled trials with Cariprazine in schizophrenia, the mean changes from baseline in weight at 12, 24, and 48 weeks were 1.2 kg, 1.7 kg, and 2.5 kg, respectively.
Leukopenia, Neutropenia, and Agranulocytosis
Leukopenia and neutropenia have been reported during treatment with antipsychotic agents, including Cariprazine. Agranulocytosis (including fatal cases) has been reported with other agents in the class.
Possible risk factors for leukopenia and neutropenia include pre-existing low white blood cell count (WBC) or absolute neutrophil count (ANC) and history of drug-induced leukopenia or neutropenia. In patients with a pre-existing low WBC or ANC or a history of drug-induced leukopenia or neutropenia, perform a complete blood count (CBC) frequently during the first few months of therapy. In such patients, consider discontinuation of Cariprazine 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 Cariprazine in patients with absolute neutrophil count < 1000/mm3 and follow their WBC until recovery.
Orthostatic Hypotension and Syncope
Atypical antipsychotics cause orthostatic hypotension and syncope. Generally, the risk is greatest during initial dose titration and when increasing the dose. Symptomatic orthostatic hypotension was infrequent in trials of Cariprazine and was not more frequent on Cariprazine than placebo. Syncope was not observed.
Orthostatic vital signs should be monitored in patients who are vulnerable to hypotension (e.g., elderly patients, patients with dehydration, hypovolemia, and concomitant treatment with antihypertensive medications), patients with known cardiovascular disease (history of myocardial infarction, ischemic heart disease, heart failure, or conduction abnormalities), and patients with cerebrovascular disease. Cariprazine has not been evaluated in patients with a recent history of myocardial infarction or unstable cardiovascular disease. Such patients were excluded from pre-marketing clinical trials.
Seizures
Like other antipsychotic drugs, Cariprazine may cause seizures. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Conditions that lower the seizure threshold may be more prevalent in older patients.
Potential for Cognitive and Motor Impairment
Cariprazine, like other antipsychotics, has the potential to impair judgment, thinking, or motor skills.
In 6-week schizophrenia trials, somnolence (hypersomnia, sedation, and somnolence) was reported in 7% of Cariprazine-treated patients compared to 6% of placebo-treated patients. In 3-week bipolar mania trials, somnolence was reported in 8% of Cariprazine-treated patients compared to 4% of placebo-treated patients.
Patients should be cautioned about operating hazardous machinery, including motor vehicles, until they are reasonably certain that therapy with Cariprazine does not affect them adversely.
Body Temperature Dysregulation
Atypical antipsychotics may disrupt the body's ability to reduce core body temperature. Strenuous exercise, exposure to extreme heat, dehydration, and anticholinergic medications may contribute to an elevation in core body temperature; use Cariprazine with caution in patient who may experience these conditions.
Dysphagia
Esophageal dysmotility and aspiration have been associated with antipsychotic drug use. Dysphagia has been reported with Cariprazine. Cariprazine and other antipsychotic drugs should be used cautiously in patients at risk for aspiration.

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 information below is derived from the clinical trial database for Cariprazine, consisting of 1733 patients with schizophrenia (aged 18 to 65) and 1025 patients with manic or mixed episodes associated with bipolar I disorder (aged 18 to 65) exposed to one or more doses with a total experience of 566.5 patient-years. Of these patients, 1317 participated in placebo-controlled, 6-week schizophrenia trials with doses ranging from 1.5 mg to 12 mg/day and 623 participated in placebo-controlled, 3-week bipolar mania trials with doses ranging from 3 mg to 12 mg/day. A total of 364 Cariprazine-treated patients had at least 24 weeks of exposure and 239 Cariprazine-treated patients had at least 48 weeks of exposure.
Patients with Schizophrenia
The following findings are based on four placebo-controlled, 6-week schizophrenia trials with Cariprazine doses ranging from 1.5 to 12 mg once daily.
- Adverse Reactions Associated with Discontinuation of Treatment: There was no single adverse reaction leading to discontinuation that occurred at a rate of ≥ 2% in Cariprazine-treated patients and at least twice the rate of placebo.
- Common Adverse Reactions (≥ 5% and at least twice the rate of placebo): extrapyramidal symptoms and akathisia.
Adverse Reactions with an incidence of ≥ 2% and greater than placebo, at any dose are shown in TABLE 3.
- Table 3. Adverse Reactions Occurring in ≥ 2% of Cariprazine-treated Patients and > Placebo-treated Adult Patients in 6-Week Schizophrenia Trials
VRAYLAR: Cariprazine's Brand name
Patients with Bipolar Mania
The following findings are based on three placebo-controlled, 3-week bipolar mania trials with Cariprazine doses ranging from 3 to 12 mg once daily.
- Adverse Reactions Associated with Discontinuation of Treatment: The only adverse reaction leading to discontinuation that occurred at a rate of ≥ 2% in Cariprazine-treated patients and at least twice the rate of placebo was akathisia (2%). Overall, 12% of the patients who received Cariprazine discontinued treatment due to an adverse reaction, compared with 7% of placebo-treated patients in these trials.
- Common Adverse Reactions (≥ 5% and at least twice the rate of placebo): extrapyramidal symptoms, akathisia, dyspepsia, vomiting, somnolence, and restlessness.
Adverse Reactions with an incidence of ≥ 2% and greater than placebo at any dose are shown in TABLE 4.

VRAYLAR: Cariprazine's Brand name
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. Although these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and higher doses of first-generation antipsychotic drugs. An elevated risk of acute dystonia is observed in males and younger age groups.
Extrapyramidal Symptoms (EPS) and Akathisia
In schizophrenia and bipolar mania trials, data were objectively collected using the Simpson Angus Rating Scale (SAS) for treatment-emergent EPS (parkinsonism) (SAS total score ≤ 3 at baseline and > 3 post-baseline) and the Barnes Akathisia Scale (BARS) for treatment-emergent akathisia (BARS total score ≤ 2 at baseline and > 2 post-baseline).
In 6-week schizophrenia trials, the incidence of reported events related to extrapyramidal symptoms (EPS), excluding akathisia and restlessness was 17% for Cariprazine-treated patients versus 8% for placebo-treated patients. These events led to discontinuation in 0.3% of Cariprazine-treated patients versus 0.2% of placebo-treated patients. The incidence of akathisia was 11% for Cariprazine-treated patients versus 4% for placebo-treated patients. These events led to discontinuation in 0.5% of Cariprazine-treated patients versus 0.2% of placebo-treated patients. The incidence of EPS is shown in TABLE 5.
- Table 5. Incidence of EPS Compared to Placebo in 6-Week Schizophrenia Studies
VRAYLAR: Cariprazine's Brand name
In 3-week bipolar mania trials, the incidence of reported events related to extrapyramidal symptoms (EPS), excluding akathisia and restlessness, was 28% for Cariprazine-treated patients versus 12% for placebo-treated patients. These events led to a discontinuation in 1% of Cariprazine-treated patients versus 0.2% of placebo-treated patients. The incidence of akathisia was 20% for Cariprazine-treated patients versus 5% for placebo-treated patients. These events led to discontinuation in 2% of Cariprazine-treated patients versus 0% of placebo-treated patients. The incidence of EPS is provided in TABLE 6.

In the long-term uncontrolled schizophrenia (48-week) and bipolar mania (16-week) trials, the incidence of cataracts was 0.1% and 0.2%, respectively. The development of cataracts was observed in nonclinical studies. The possibility of lenticular changes or cataracts cannot be excluded at this time.
Vital Signs Changes
There were no clinically meaningful differences between Cariprazine-treated patients and placebo-treated patients in mean change from baseline to endpoint in supine blood pressure parameters except for an increase in supine diastolic blood pressure in the 9 - 12 mg/day Cariprazine-treated schizophrenia patients.
Pooled data from 6-week schizophrenia and 3-week bipolar mania trials are shown in TABLES 7 and 8.

Changes in Laboratory Tests
The proportions of patients with transaminase elevations of ≥3 times the upper limits of the normal reference range in 6-week schizophrenia trials ranged between 1% and 2% for Cariprazine-treated patients, increasing with dose, and was 1% for placebo-treated patients. The proportions of patients with transaminase elevations of ≥3 times the upper limits of the normal reference range in 3-week bipolar mania trials ranged between 2% and 4% for Cariprazine-treated patients depending on dose group administered and 2% for placebo-treated patients.
The proportions of patients with elevations of creatine phosphokinase (CPK) greater than 1000 U/L in 6-week schizophrenia trials ranged between 4% and 6% for Cariprazine-treated patients, increasing with dose, and was 4% for placebo-treated patients. The proportions of patients with elevations of CPK greater than 1000 U/L in 3-week bipolar mania trials was about 4% in Cariprazine and placebo-treated patients.
Other Adverse Reactions Observed During the Pre-marketing Evaluation of Cariprazine
Adverse reactions listed below were reported by patients treated with Cariprazine at doses of ≥ 1.5 mg once daily within the database of 2758 Cariprazine-treated patients. The reactions listed are those that could be of clinical importance, as well as reactions that are plausibly drug-related on pharmacologic or other grounds. Reactions that appear elsewhere in the Cariprazine label are not included.

Drugs Having No Clinically Important Interactions with Cariprazine
Based on in vitro studies, Cariprazine is unlikely to cause clinically significant pharmacokinetic drug interactions with substrates of CYP1A2, CYP2A6, CYP2C9, CYP2C19, CYP2D6, CYP2E, and CYP3A4, or OATP1B1, OATP1B3, BCRP, OCT2, OAT1 and OAT3.
Use in Specific Populations
Pregnancy
- Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to Cariprazine during pregnancy. For more information, contact the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/.
- Risk Summary
Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. There are no available data on Cariprazine use in pregnant women to inform any drug-associated risks for birth defects or miscarriage. Based on animal data Cariprazine may cause fetal harm. Administration of Cariprazine to rats during the period of organogenesis caused malformations, lower pup survival, and developmental delays at drug exposures less than the human exposure at the maximum recommended human dose (MRHD) of 6 mg/day. However, Cariprazine was not teratogenic in rabbits at doses up to 4.6 times the MRHD of 6 mg/day. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Advise pregnant women of the potential risk to a fetus.
- Clinical Considerations
- Fetal/Neonatal Adverse Reactions
Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder have been reported in neonates whose mothers were exposed to antipsychotic drugs during the third trimester of pregnancy. These symptoms have varied in severity. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately.
- Data
- Animal Data
Administration of Cariprazine to pregnant rats during the period of organogenesis at oral doses of 0.5, 2.5, and 7.5 mg/kg/day which are 0.2 to 3.5 times the maximum recommended human dose (MRHD) of 6 mg/day based on AUC of total Cariprazine (i.e. sum of Cariprazine, DCAR, and DDCAR) caused fetal developmental toxicity at all doses which included reduced body weight, decreased male anogenital distance and skeletal malformations of bent limb bones, scapula and humerus. These effects occurred in the absence or presence of maternal toxicity. Maternal toxicity, observed as a reduction in body weight and food consumption, occurred at doses 1.2 and 3.5-times the MRHD of 6 mg/kg/day based on AUC of total Cariprazine. At these doses, Cariprazine caused fetal external malformations (localized fetal thoracic edema), visceral variations (undeveloped/underdeveloped renal papillae and/or distended urethrae), and skeletal developmental variations (bent ribs, unossified sternebrae). Cariprazine had no effect on fetal survival.
Administration of Cariprazine to pregnant rats during pregnancy and lactation at oral doses of 0.1, 0.3, and 1 mg/kg/day which are 0.03 to 0.4 times the MRHD of 6 mg/day based on AUC of total Cariprazine caused a decrease in postnatal survival, birth weight, and post-weaning body weight of first generation pups at the dose that is 0.4 times the MRHD of 6 mg/day based on AUC of total Cariprazine in absence of maternal toxicity. First generation pups also had pale, cold bodies and developmental delays (renal papillae not developed or underdeveloped and decreased auditory startle response in males). Reproductive performance of the first generation pups was unaffected; however, the second generation pups had clinical signs and lower body weight similar to these of the first generation pups.
Administration of Cariprazine to pregnant rabbits during the period of organogenesis at oral doses of 0.1, 1, and 5 mg/kg/day, which are 0.02 to 4.6 times the MRHD of 6 mg/day based on AUC of total Cariprazine was not teratogenic. Maternal body weight and food consumption were decreased at 4.6 times the MRHD of 6 mg/day based on AUC of total Cariprazine; however, no adverse effects were observed on pregnancy parameters or reproductive organs.
Pregnancy Category (AUS):
There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Cariprazine in women who are pregnant.
Labor and Delivery
There is no FDA guidance on use of Cariprazine during labor and delivery.
Nursing Mothers
Lactation studies have not been conducted to assess the presence of Cariprazine in human milk, the effects on the breastfed infant, or the effects on milk production. Cariprazine is present in rat milk. The development and health benefits of breastfeeding should be considered along with the mother's clinical need for Cariprazine and any potential adverse effects on the breastfed infant from Cariprazine or from the underlying maternal condition.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established. Pediatric studies of Cariprazine have not been conducted. Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery.
Geriatic Use
Clinical trials of Cariprazine in the treatment of schizophrenia and bipolar mania did not include sufficient numbers of patients aged 65 and older to determine whether or not they respond differently from younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Elderly patients with dementia-related psychosis treated with Cariprazine are at an increased risk of death compared to placebo. Cariprazine is not approved for the treatment of patients with dementia-related psychosis.
Gender
There is no FDA guidance on the use of Cariprazine with respect to specific gender populations.
Race
There is no FDA guidance on the use of Cariprazine with respect to specific racial populations.
Renal Impairment
No dosage adjustment for Cariprazine is required in patients with mild to moderate (CrCL ≥ 30 mL/minute) renal impairment.
Usage of Cariprazine is not recommended in patients with severe renal impairment (CrCL < 30 mL/minute). Cariprazine has not been evaluated in this patient population.
Hepatic Impairment
No dosage adjustment for Cariprazine is required in patients with mild to moderate hepatic impairment (Child-Pugh score between 5 and 9). Usage of Cariprazine is not recommended in patients with severe hepatic impairment (Child-Pugh score between 10 and 15). Cariprazine has not been evaluated in this patient population.
Females of Reproductive Potential and Males

In pre-marketing clinical trials involving Cariprazine in approximately 5000 patients or healthy subjects, accidental acute overdosage (48 mg/day) was reported in one patient. This patient experienced orthostasis and sedation. The patient fully recovered the same day.
- Management of Overdosage
No specific antidotes for Cariprazine are known. In managing overdose, provide supportive care, including close medical supervision and monitoring, and consider the possibility of multiple drug involvement. In case of an overdose, consult a Certified Poison Control Center (1-800-222-1222) for up-to-date guidance and advice.
Pharmacology
Mechanism of Action
The mechanism of action of Cariprazine in schizophrenia and bipolar I disorder is unknown. However, the efficacy of Cariprazine could be mediated through a combination of partial agonist activity at central dopamine D2 and serotonin 5-HT1A receptors and antagonist activity at serotonin 5-HT2A receptors. Cariprazine forms two major metabolites, desmethyl cariprazine (DCAR) and didesmethyl cariprazine (DDCAR), that have in vitro receptor binding profiles similar to the parent drug.
Structure
The active ingredient of Cariprazine HCl, an atypical antipsychotic. The chemical name is trans-N-{4-[2-[4-(2,3-dichlorophenyl)piperazine-1-yl]ethyl]cyclohexyl}-N',N'-dimethylurea hydrochloride; its empirical formula is C21H33Cl3N4O and its molecular weight is 463.9 g/mol. The chemical structure is:
Cariprazine capsules are intended for oral administration only. Each hard gelatin capsule contains a white to off-white powder of Cariprazine HCl, which is equivalent to 1.5, 3, 4.5, or 6 mg of Cariprazine base. In addition, capsules include the following inactive ingredients: gelatin, magnesium stearate, pregelatinized starch, shellac, and titanium dioxide. Colorants include black iron oxide (1.5, 3, and 6 mg), FD&C Blue 1 (3, 4.5, and 6 mg), FD&C Red 3 (6 mg), FD&C Red 40 (3 and 4.5 mg), or yellow iron oxide (3 and 4.5 mg).
Pharmacodynamics
Cariprazine acts as a partial agonist at the dopamine D3 and D2 receptors with high binding affinity (Ki values 0.085 nM, and 0.49 nM (D2L) and 0.69 nM (D2S), respectively) and at the serotonin 5-HT1A receptors (Ki value 2.6 nM). Cariprazine acts as an antagonist at 5-HT2B and 5-HT2A receptors with high and moderate binding affinity (Ki values 0.58 nM and 18.8 nM respectively) as well as it binds to the histamine H1 receptors (Ki value 23.2 nM). Cariprazine shows lower binding affinity to the serotonin 5-HT2C and α1A- adrenergic receptors (Ki values 134 nM and 155 nM, respectively) and has no appreciable affinity for cholinergic muscarinic receptors (IC50>1000 nM).
- Effect on QTc Interval
At a dose three-times the maximum recommended dose, Cariprazine does not prolong the QTc interval to clinically relevant extent.
Pharmacokinetics
Cariprazine activity is thought to be mediated by Cariprazine and its two major active metabolites, desmethyl cariprazine (DCAR) and didesmethyl cariprazine (DDCAR), which are pharmacologically equipotent to Cariprazine.
After multiple dose administration of Cariprazine, mean Cariprazine and DCAR concentrations reached steady state at around Week 1 to Week 2 and mean DDCAR concentrations appeared to be approaching steady state at around Week 4 to Week 8 in a 12-week study (FIGURE 1). The half-lives based on time to reach steady state, estimated from the mean concentration-time curves, are 2 to 4 days for Cariprazine, and approximately 1 to 3 weeks for DDCAR. The time to reach steady state for the major active metabolite DDCAR was variable across patients, with some patients not achieving steady state at the end of the 12 week treatment. Mean concentrations of DCAR and DDCAR are approximately 30% and 400%, respectively, of Cariprazine concentrations by the end of 12-week treatment.
After discontinuation of the drug, cariprazine, DCAR, and DDCAR plasma concentrations declined in a multi-exponential manner. Mean plasma concentrations of DDCAR decreased by about 50%, 1 week after the last dose and mean Cariprazine and DCAR concentration dropped by about 50% in about 1 day. There was an approximately 90% decline in plasma exposure within 1 week for Cariprazine and DCAR, and at about 4 weeks for DDCAR. Following a single dose of 1 mg of Cariprazine administration, DDCAR remained detectable 8 weeks post-dose.
After multiple dosing of Cariprazine, plasma exposure of cariprazine, DCAR, and DDCAR, increases approximately proportionally over the therapeutic dose range.
- Figure 1. Plasma Concentration (Mean ± SE)-Time Profile During and Following 12-weeks of Treatment with Cariprazine 6 mg/day(a)
After single dose administration of Cariprazine, the peak plasma Cariprazine concentration occurred in approximately 3-6 hours.
Administration of a single dose of 1.5 mg Cariprazine capsule with a high-fat meal did not significantly affect the Cmax and AUC of Cariprazine or DCAR.
Cariprazine and its major active metabolites are highly bound (91 to 97%) to plasma proteins.
Elimination
Cariprazine is extensively metabolized by CYP3A4 and, to a lesser extent, by CYP2D6 to DCAR and DDCAR. DCAR is further metabolized into DDCAR by CYP3A4 and CYP2D6. DDCAR is then metabolized by CYP3A4 to a hydroxylated metabolite.
Following administration of 12.5 mg/day Cariprazine to patients with schizophrenia for 27 days, about 21% of the daily dose was found in urine, with approximately 1.2% of the daily dose was excreted in urine as unchanged Cariprazine.
Studies in Specific Populations
Compared to healthy subjects, patients with either mild or moderate hepatic impairment (Child-Pugh score between 5 and 9) had approximately 25% higher exposure (Cmax and AUC) for Cariprazine and approximately 45% lower exposure for the major active metabolites, DCAR and DDCAR, following a single dose of 1 mg Cariprazine or 0.5 mg Cariprazine for 14 days.
Cariprazine and its major active metabolites are minimally excreted in urine. Pharmacokinetic analyses indicated no significant relationship between plasma clearance and creatinine clearance.
- CYP2D6 Poor Metabolizers
CYP2D6 poor metabolizer status does not have clinically relevant effect on pharmacokinetics of Cariprazine, DCAR, or DDCAR.
- Age, Sex, Race
Age, sex, or race does not have clinically relevant effect on pharmacokinetics of Cariprazine, DCAR, or DDCAR.
Drug Interaction Studies
- In vitro studies
Cariprazine and its major active metabolites did not induce CYP1A2 and CYP3A4 enzymes and were weak inhibitors of CYP1A2, CYP2C9, CYP2D6, and CYP3A4 in vitro. Cariprazine was also a weak inhibitor of CYP2C19, CYP2A6, and CYP2E1 in vitro.
Cariprazine and its major active metabolites are not substrates of P-glycoprotein (P-gp), the organic anion transporting polypeptide 1B1 and 1B3 (OATP1B1 and OATP1B3), and the breast cancer resistance protein (BCRP).
Cariprazine and its major active metabolites were poor or non-inhibitors of transporters OATP1B1, OATP1B3, BCRP, organic cation transporter 2 (OCT2), and organic anion transporters 1 and 3 (OAT1 and OAT3) in vitro. The major active metabolites were also poor or non-inhibitors of transporter P-gp although Cariprazine was probably a P-gp inhibitor based on the theoretical GI concentrations at high doses in vitro.
- CYP3A4 inhibitors
Coadministration of ketoconazole (400 mg/day), a strong CYP3A4 inhibitor, with Cariprazine (0.5 mg/day) increased Cariprazine Cmax and AUC(0-24h) by about 3.5-fold and 4-fold, respectively; increased DDCAR Cmax and AUC(0-24h) by about 1.5-fold; and decreased DCAR Cmax and AUC(0-24h) by about one-third. The impact of moderate CYP3A4 inhibitors has not been studied.
- CYP3A4 inducers
CYP3A4 is responsible for the formation and elimination of the active metabolites of Cariprazine. The effect of CYP3A4 inducers on the plasma exposure of Cariprazineand its major active metabolites has not been evaluated, and the net effect is unclear.
- CYP2D6 inhibitors
CYP2D6 inhibitors are not expected to influence pharmacokinetics of Cariprazine, DCAR or DDCAR based on the observations in CYP2D6 poor metabolizers.
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment of Fertility
There was no increase in the incidence of tumors following daily oral administration of Cariprazine to rats for 2 years and to Tg.rasH2 mice for 6 months at doses which are up to 4 and 19 times respectively, the MRHD of 6 mg/day based on AUC of total Cariprazine, (i.e. sum of AUC values of Cariprazine, DCAR and DDCAR).
Rats were administered Cariprazine at oral doses of 0.25, 0.75, and 2.5 (males)/1, 2.5, and 7.5 mg/kg/day (females) (which are 0.2 to 1.8 (males)/ 0.8 to 4.1 (females) times the MRHD of 6 mg/day based on AUC of total Cariprazine.
Tg.rasH2 mice were administered Cariprazine at oral doses of 1, 5, and 15 (males)/5, 15, and 50 mg/kg/day (females) which are 0.2 to 7.9 (males)/2.6 to 19 (females) times the MRHD of 6 mg/day based on AUC of total Cariprazine.
Cariprazine was not mutagenic in the in vitro bacterial reverse mutation assay, nor clastogenic in the in vitro human lymphocyte chromosomal aberration assay or in the in vivo mouse bone marrow micronucleus assay. However, Cariprazine increased the mutation frequency in the in vitro mouse lymphoma assay under conditions of metabolic activation. The major human metabolite DDCAR was not mutagenic in the in vitro bacterial reverse mutation assay, however, it was clastogenic and induced structural chromosomal aberration in the in vitro human lymphocyte chromosomal aberration assay.
- Impairment of Fertility
Cariprazine was administered orally to male and female rats before mating, through mating and up to day 7 of gestation at doses of 1, 3, and 10 mg/kg/day which are 1.6 to 16 times the MRHD of 6 mg/day based on mg/m2. In female rats, lower fertility and conception indices were observed at all dose levels which are equal to or higher than 1.6 times the MRHD of 6 mg/day based on mg/m2. No effects on male fertility were noted at any dose up to 4.3 times the MRHD of 6 mg/day based on AUC of total Cariprazine.
Animal Toxicology and/or Pharmacology
Cariprazine caused bilateral cataract and cystic degeneration of the retina in the dog following oral daily administration for 13 weeks and/or 1 year and retinal degeneration/atrophy in the rat following oral daily administration for 2 years. Cataract in the dog was observed at 4 mg/kg/day which is 7.1 (male) and 7.7 (female) times the MRHD of 6 mg/day based on AUC of total Cariprazine. The NOEL for cataract and retinal toxicity in the dog is 2 mg/kg/day which is 5 (males) to 3.6 (females) times the MRHD of 6 mg/day based on AUC of total Cariprazine. Increased incidence and severity of retinal degeneration/atrophy in the rat occurred at all doses tested, including the low dose of 0.75 mg/kg/day, at total Cariprazine plasma levels less than clinical exposure (AUC) at the MRHD of 6 mg/day. Cataract was not observed in other repeat dose studies in pigmented mice or albino rats.
Phospholipidosis was observed in the lungs of rats, dogs, and mice (with or without inflammation) and in the adrenal gland cortex of dogs at clinically relevant exposures (AUC) of total Cariprazine. Phospholipidosis was not reversible at the end of the 1-2 month drug-free periods. Inflammation was observed in the lungs of dogs dosed daily for 1 year with a NOEL of 1 mg/kg/day which is 2.7 (males) and 1.7 (females) times the MRHD of 6 mg/day based on AUC of total Cariprazine. No inflammation was observed at the end of 2-month drug free period following administration of 2 mg/kg/day which is 5 (males) and 3.6 (females) times the MRHD of 6 mg/day based on AUC of total Cariprazine; however, inflammation was still present at higher doses.
Hypertrophy of the adrenal gland cortex was observed at clinically relevant total Cariprazine plasma concentrations in rats (females only) and mice following daily oral administration of Cariprazine for 2 years and 6 months, respectively. Reversible hypertrophy/hyperplasia and vacuolation/vesiculation of the adrenal gland cortex were observed following daily oral administration of Cariprazine to dogs for 1 year. The NOEL was 2 mg/kg/day which is 5 (males) and 3.6 (females) times the MRHD of 6 mg/day based on AUC of total Cariprazine. The relevance of these findings to human risk is unknown.
Clinical Studies
Schizophrenia
The efficacy of Cariprazine for the treatment of schizophrenia was established in three, 6-week, randomized, double-blind, placebo-controlled trials in patients (aged 18 to 60 years) who met Diagnostic and Statistical Manual of Mental Disorders 4th edition, Text Revision (DSM-IV-TR) criteria for schizophrenia. An active control arm (risperidone or aripiprazole) was included in two trials to assess assay sensitivity. In all three trials, Cariprazine was superior to placebo.
Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impressions-Severity (CGI-S) rating scales were used as the primary and secondary efficacy measures, respectively, for assessing psychiatric signs and symptoms in each trial:
- PANSS is a 30-item scale that measures positive symptoms of schizophrenia (7 items), negative symptoms of schizophrenia (7 items), and general psychopathology (16 items), each rated on a scale of 1 (absent) to 7 (extreme). The PANSS total score may range from 30 to 210 with the higher score reflecting greater severity.
- The CGI-S is a validated clinician-related scale that measures the patient's current illness state and overall clinical state on a 1 (normal, not at all ill) to 7-point (extremely ill) scale.
In each study, the primary endpoint was change from baseline in PANSS total score at the end of week 6. The change from baseline for Cariprazine and active control groups was compared to placebo. The results of the trials are shown in TABLE 10. The time course of efficacy results of Study 2 is shown in FIGURE 2.
Study 1: In a 6-week, placebo-controlled trial (N = 711) involving three fixed doses of Cariprazine (1.5, 3, or 4.5 mg/day) and an active control (risperidone), all Cariprazine doses and the active control were superior to placebo on the PANSS total score and the CGI-S.
Study 2: In a 6-week, placebo-controlled trial (N = 604) involving two fixed doses of Cariprazine (3 or 6 mg/day) and an active control (aripiprazole), both Cariprazine doses and the active control were superior to placebo on the PANSS total score and the CGI-S.
Study 3: In a 6-week, placebo-controlled trial (N = 439) involving two flexible-dose range groups of Cariprazine (3 to 6 mg/day or 6 to 9 mg/day), both Cariprazine groups were superior to placebo on the PANSS total score and the CGI-S.
The efficacy of Cariprazine was demonstrated at doses ranging from 1.5 to 9 mg/day compared to placebo. There was, however, a dose-related increase in certain adverse reactions, particularly above 6 mg. Therefore, the maximum recommended dose is 6 mg/day.
Examination of population subgroups based on age (there were few patients over 55), sex, and race did not suggest any clear evidence of differential responsiveness.

Manic or Mixed Episodes Associated with Bipolar I Disorder
The efficacy of Cariprazine in the acute treatment of bipolar mania was established in three, 3-week placebo-controlled trials in patients (mean age of 39 years, range 18 to 65 years) who met DSM-IV-TR criteria for bipolar 1 disorder with manic or mixed episodes with or without psychotic features. In all three trials, Cariprazine was superior to placebo.
Young Mania Rating Scale (YMRS) and Clinical Global Impressions-Severity scale (CGI-S) were used as the primary and secondary efficacy measures, respectively, for assessing psychiatric signs and symptoms in each trial:
The YMRS is an 11-item clinician-rated scale traditionally used to assess the degree of manic symptomatology. YMRS total score may range from 0 to 60 with a higher score reflecting greater severity. The CGI-S is validated clinician-related scale that measures the patient's current illness state and overall clinical state on a 1 (normal, not at all ill) to 7-point (extremely ill) scale. In each study, the primary endpoint was decrease from baseline in YMRS total score at the end of week 3. The change from baseline for each Cariprazine dose group was compared to placebo. The results of the trials are shown in TABLE 11. The time course of efficacy results is shown in FIGURE 3.
Study 1: In a 3-week, placebo-controlled trial (N = 492) involving two flexible-dose range groups of Cariprazine (3 to 6 mg/day or 6 to 12 mg/day), both Cariprazine dose groups were superior to placebo on the YMRS total score and the CGI-S. The 6 to 12 mg/day dose group showed no additional advantage.
Study 2: In a 3-week, placebo-controlled trial (N = 235) involving a flexible-dose range of Cariprazine (3 to 12 mg/day), Cariprazine was superior to placebo on the YMRS total score and the CGI-S.
Study 3: In a 3-week, placebo-controlled trial (N = 310) involving a flexible-dose range of Cariprazine (3 to 12 mg/day), Cariprazine was superior to placebo on the YMRS total score and the CGI-S.
The efficacy of Cariprazine was established at doses ranging from 3 to 12 mg/day. Doses above 6 mg did not appear to have additional benefit over lower doses (TABLE 11) and there was a dose-related increase in certain adverse reactions. Therefore, the maximum recommended dose is 6 mg/day.
Examination of population subgroups based on age (there were few patients over 55), sex, and race did not suggest any clear evidence of differential responsiveness.
