  • BOXED WARNING (What is this?)

    WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS; and SUICIDAL THOUGHTS AND BEHAVIORS

    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 [see WARNINGS AND PRECAUTIONS (5.1)]. Quetiapine fumarate extended-release tablet is not approved for the treatment of patients with dementia-related psychosis [see WARNINGS AND PRECAUTIONS (5.1)].

    Suicidal Thoughts and Behavior

    Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term studies. These studies did not show an increase in the risk of suicidal thoughts and behavior with antidepressant use in patients over age 24; there was a reduction in risk with antidepressant use in patients aged 65 and older [see WARNINGS AND PRECAUTIONS (5.2)]. In patients of all ages who are started on antidepressant therapy, monitor closely for worsening, and for emergence of suicidal thoughts and behaviors. Advise families and caregivers of the need for close observation and communication with the prescriber [see WARNINGS AND PRECAUTIONS (5.2)]

    Quetiapine fumarate extended-release tablet is not approved for use in pediatric patients under ten years of age [see USE IN SPECIFIC POPULATIONS (8.4)].

  • 1 INDICATIONS AND USAGE

    1.1 Schizophrenia

    Quetiapine fumarate extended-release tablet is indicated for the treatment of schizophrenia. The efficacy of quetiapine fumarate extended-release tablet in schizophrenia was established in one 6-week and one maintenance trial in adults with schizophrenia. Efficacy was supported by three 6-week trials in adults with schizophrenia and one 6-week trial in adolescents with schizophrenia (13 to 17 years) treated with quetiapine fumarate tablet [see CLINICAL STUDIES (14.1)].

    1.2 Bipolar Disorder

    Quetiapine fumarate extended-release tablet is indicated for the acute treatment of manic or mixed episodes associated with bipolar I disorder, both as monotherapy and as an adjunct to lithium or divalproex. The efficacy of quetiapine fumarate extended-release tablet in manic or mixed episodes of bipolar I disorder was established in one 3-week trial in adults with manic or mixed episodes associated with bipolar I disorder. Efficacy was supported by two 12-week monotherapy trials and one 3-week adjunctive trial in adults with manic episodes associated with bipolar I disorder as well as one 3-week monotherapy trial in children and adolescents (10 to 17 years) with manic episodes associated with bipolar I disorder treated with quetiapine fumarate tablet [see CLINICAL STUDIES (14.2)].

    Quetiapine fumarate extended-release tablet is indicated for the acute treatment of depressive episodes associated with bipolar disorder. The efficacy of quetiapine fumarate extended-release tablet was established in one 8-week trial in adults with bipolar I or II disorder and supported by two 8-week trials in adults with bipolar I or II disorder treated with quetiapine fumarate tablet [see CLINICAL STUDIES (14.2)].

    Quetiapine fumarate extended-release tablet is indicated for the maintenance treatment of bipolar I disorder, as an adjunct to lithium or divalproex. Efficacy was extrapolated from two maintenance trials in adults with bipolar I disorder treated with quetiapine fumarate tablet. The effectiveness of monotherapy for the maintenance treatment of bipolar I disorder has not been systematically evaluated in controlled clinical trials [see CLINICAL STUDIES (14.2)].

    1.3 Adjunctive Treatment of Major Depressive Disorder (MDD)

    Quetiapine fumarate extended-release tablet is indicated for use as adjunctive therapy to antidepressants for the treatment of MDD. The efficacy of quetiapine fumarate extended-release tablet as adjunctive therapy to antidepressants in MDD was established in two 6-week trials in adults with MDD who had an inadequate response to antidepressant treatment [see CLINICAL STUDIES (14.3)].

    1.4 Special Considerations in Treating Pediatric Schizophrenia and Bipolar I Disorder

    Pediatric schizophrenia and bipolar I disorder are serious mental disorders, however, diagnosis can be challenging. For pediatric schizophrenia, symptom profiles can be variable, and for bipolar I disorder, patients may have variable patterns of periodicity of manic or mixed symptoms. It is recommended that medication therapy for pediatric schizophrenia and bipolar I disorder be initiated only after a thorough diagnostic evaluation has been performed and careful consideration given to the risks associated with medication treatment. Medication treatment for both pediatric schizophrenia and bipolar I disorder is indicated as part of a total treatment program that often includes psychological, educational and social interventions.

    Maintenance Treatment for Schizophrenia and Bipolar I Disorder

    Maintenance Treatment:

    Patients should be periodically reassessed to determine the need for maintenance treatment and the appropriate dose for such treatment [see CLINICAL STUDIES (14.1, 14.2)].

    2.3 Dose Modifications in Elderly Patients

    Consideration should be given to a slower rate of dose titration and a lower target dose in the elderly and in patients who are debilitated or who have a predisposition to hypotensive reactions [see USE IN SPECIFIC POPULATIONS (8.5, 8.7), and CLINICAL PHARMACOLOGY (12.3)]. When indicated, dose escalation should be performed with caution in these patients.

    Elderly patients should be started on quetiapine fumarate extended-release tablet 50 mg/day and the dose can be increased in increments of 50 mg/day depending on the clinical response and tolerability of the individual patient.

    2.4 Dose Modifications in Hepatically Impaired Patients

    Patients with hepatic impairment should be started on quetiapine fumarate extended-release tablet 50 mg/day. The dose can be increased daily in increments of 50 mg/day to an effective dose, depending on the clinical response and tolerability of the patient.

    2.5 Dose Modifications when used with CYP3A4 Inhibitors

    Quetiapine fumarate extended-release tablet dose should be reduced to one sixth of original dose when co-medicated with a potent CYP3A4 inhibitor (e.g. ketoconazole, itraconazole, indinavir, ritonavir, nefazodone, etc.). When the CYP3A4 inhibitor is discontinued, the dose of quetiapine fumarate extended-release tablet should be increased by 6 fold [see CLINICAL PHARMACOLOGY (12.3) and DRUG INTERACTIONS 7.1)].

    2.6 Dose Modifications when used with CYP3A4 Inducers

    Quetiapine fumarate extended-release tablet dose should be increased up to 5 fold of the original dose when used in combination with a chronic treatment (e.g., greater than 7 to 14 days) of a potent CYP3A4 inducer (e.g. phenytoin, carbamazepine, rifampin, avasimibe, St. John's wort etc.). The dose should be titrated based on the clinical response and tolerance of the individual patient. When the CYP3A4 inducer is discontinued, the dose of quetiapine fumarate extended-release tablet should be reduced to the original level within 7 to 14 days [see CLINICAL PHARMACOLOGY (12.3) and DRUG INTERACTIONS (7.1)].

    2.7 Re-initiation of Treatment in Patients Previously Discontinued

    Although there are no data to specifically address re-initiation of treatment, it is recommended that when restarting therapy of patients who have been off quetiapine fumarate extended-release tablet for more than one-week, the initial dosing schedule should be followed. When restarting patients who have been off quetiapine fumarate extended-release tablet for less than one-week, gradual dose escalation may not be required and the maintenance dose may be re-initiated.

    2.8 Switching Patients from Quetiapine Fumarate Tablets to Quetiapine Fumarate Extended-Release Tablets

    Patients who are currently being treated with quetiapine fumarate tablets (immediate release formulation) may be switched to quetiapine fumarate extended-release tablet at the equivalent total daily dose taken once daily. Individual dosage adjustments may be necessary.

    2.9 Switching from Antipsychotics

    There are no systematically collected data to specifically address switching patients from other antipsychotics to quetiapine fumarate extended-release tablet, or concerning concomitant administration with other antipsychotics. While immediate discontinuation of the previous antipsychotic treatment may be acceptable for some patients, more gradual discontinuation may be most appropriate for others. In all cases, the period of overlapping antipsychotic administration should be minimized. When switching patients from depot antipsychotics, if medically appropriate, initiate quetiapine fumarate extended-release tablet therapy in place of the next scheduled injection. The need for continuing existing extrapyramidal syndrome medication should be re-evaluated periodically.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 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. Analysis of 17 placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death 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 the placebo group. 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. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. Quetiapine fumarate extended-release tablet is not approved for the treatment of patients with dementia-related psychosis [see BOXED WARNING].

    5.2 Suicidal Thoughts and Behaviors in Adolescents and Young Adults

    Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide. There has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment. Pooled analyses of short-term placebo-controlled trials of antidepressant drugs (SSRIs and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18 to 24) with major depressive disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction with antidepressants compared to placebo in adults aged 65 and older.

    The pooled analyses of placebo-controlled trials in children and adolescents with MDD, obsessive compulsive disorder (OCD), or other psychiatric disorders included a total of 24 short-term trials of 9 antidepressant drugs in over 4,400 patients. The pooled analyses of placebo-controlled trials in adults with MDD or other psychiatric disorders included a total of 295 short-term trials (median duration of 2 months) of 11 antidepressant drugs in over 77,000 patients. There was considerable variation in risk of suicidality among drugs, but a tendency toward an increase in the younger patients for almost all drugs studied. There were differences in absolute risk of suicidality across the different indications, with the highest incidence in MDD. The risk differences (drug vs. placebo), however, were relatively stable within age strata and across indications. These risk differences (drug-placebo difference in the number of cases of suicidality per 1000 patients treated) are provided in Table 2.

    Table 2:Drug-Placebo Difference in Number of Cases of Suicidality per 1000 Patients Treated

    Decreases Compared to Placebo
    25 to 64
    1 fewer case
    ≥65
    6 fewer cases

    No suicides occurred in any of the pediatric trials. There were suicides in the adult trials, but the number was not sufficient to reach any conclusion about drug effect on suicide.

    It is unknown whether the suicidality risk extends to longer-term use, i.e., beyond several months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with depression that the use of antidepressants can delay the recurrence of depression.

    All patients being treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the initial few months of a course of drug therapy, or at times of dose changes, either increases or decreases.

    The following symptoms, anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, and mania, have been reported in adult and pediatric patients being treated with antidepressants for major depressive disorder as well as for other indications, both psychiatric and non-psychiatric. Although a causal link between the emergence of such symptoms and either the worsening of depression and/or the emergence of suicidal impulses has not been established, there is concern that such symptoms may represent precursors to emerging suicidality.

    Consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medication, in patients whose depression is persistently worse, or who are experiencing emergent suicidality or symptoms that might be precursors to worsening depression or suicidality, especially if these symptoms are severe, abrupt in onset, or were not part of the patient's presenting symptoms.

    Families and caregivers of patients being treated with antidepressants for major depressive disorder or other indications, both psychiatric and non-psychiatric, should be alerted about the need to monitor patients for the emergence of agitation, irritability, unusual changes in behavior, and the other symptoms described above, as well as the emergence of suicidality, and to report such symptoms immediately to healthcare providers. Such monitoring should include daily observation by families and caregivers. Prescriptions for quetiapine fumarate extended-release tablet should be written for the smallest quantity of tablets consistent with good patient management, in order to reduce the risk of overdose.

    Screening Patients for Bipolar Disorder

    A major depressive episode may be the initial presentation of bipolar disorder. It is generally believed (though not established in controlled trials) that treating such an episode with an antidepressant alone may increase the likelihood of precipitation of a mixed/manic episode in patients at risk for bipolar disorder. Whether any of the symptoms described above represent such a conversion is unknown. However, prior to initiating treatment with an antidepressant, including quetiapine fumarate extended-release tablet, patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder; such screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression.

    5.3 Cerebrovascular Adverse Reactions, Including Stroke, in Elderly Patients with Dementia-Related Psychosis

    In placebo-controlled trials with risperidone, aripiprazole, and olanzapine in elderly subjects with dementia, there was a higher incidence of cerebrovascular adverse reactions (cerebrovascular accidents and transient ischemic attacks), including fatalities, compared to placebo-treated subjects. Quetiapine fumarate extended-release tablet is not approved for the treatment of patients with dementia-related psychosis [see BOXED WARNING and WARNINGS AND PRECAUTIONS (5.1)].

    5.4 Neuroleptic Malignant System NMS

    A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with administration of antipsychotic drugs, including quetiapine. Rare cases of NMS have been reported with quetiapine. Clinical manifestations of NMS are 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 diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to exclude cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology.

    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. There is no general agreement about specific pharmacological treatment regimens for NMS.

    If a patient requires antipsychotic drug treatment after recovery from NMS, the potential reintroduction of drug therapy should be carefully considered. The patient should be carefully monitored since recurrences of NMS have been reported.

    5.5 Metabolic Changes

    Atypical antipsychotic drugs have been associated with metabolic changes that include hyperglycemia/diabetes mellitus, dyslipidemia, and body weight gain. While all of the drugs in the class have been shown to produce some metabolic changes, each drug has its own specific risk profile. In some patients, a worsening of more than one of the metabolic parameters of weight, blood glucose, and lipids was observed in clinical studies. Changes in these metabolic profiles should be managed as clinically appropriate.

    Hyperglycemia and Diabetes Mellitus

    Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics, including quetiapine. Assessment of the relationship between atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an increased background risk of diabetes mellitus in patients with schizophrenia and the increasing incidence of diabetes mellitus in the general population. Given these confounders, the relationship between atypical antipsychotic use and hyperglycemia-related adverse reactions is not completely understood. However, epidemiological studies suggest an increased risk of hyperglycemia-related adverse reactions in patients treated with the atypical antipsychotics. Precise risk estimates for hyperglycemia-related adverse reactions in patients treated with atypical antipsychotics are not available.

    Patients with an established diagnosis of diabetes mellitus who are started on atypical antipsychotics should be monitored regularly for worsening of glucose control. Patients with risk factors for diabetes mellitus (e.g., obesity, family history of diabetes) who are starting treatment with atypical antipsychotics should undergo fasting blood glucose testing at the beginning of treatment and periodically during treatment. 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 during treatment with atypical antipsychotics should 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.

    In a 24-week trial (active-controlled, 115 patients treated with quetiapine tablet) designed to evaluate glycemic status with oral glucose tolerance testing of all patients, at week 24 the incidence of post-glucose challenge glucose level ≥ 200 mg/dL was 1.7% and the incidence of a fasting blood glucose level ≥ 126 mg/dL was 2.6%. The mean change in fasting glucose from baseline was 3.2 mg/dL and mean change in 2-hour glucose from baseline was -1.8 mg/dL for quetiapine.

    In 2 long-term placebo-controlled randomized withdrawal clinical trials for bipolar I disorder maintenance, mean exposure of 213 days for quetiapine fumarate tablet (646 patients) and 152 days for placebo (680 patients), the mean change in glucose from baseline was +5.0 mg/dL for quetiapine and -0.05 mg/dL for placebo. The exposure-adjusted rate of any increased blood glucose level (≥ 126 mg/dL) for patients more than 8 hours since a meal (however, some patients may not have been precluded from calorie intake from fluids during fasting period) was 18.0 per 100 patient years for quetiapine fumarate tablet (10.7% of patients; n=556) and 9.5 for placebo per 100 patient years (4.6% of patients; n=581).

    Children and Adolescents:

    Safety and effectiveness of quetiapine fumarate extended-release tablet is supported from studies of quetiapine fumarate tablet in children and adolescent patients 10 to 17 years of age [see CLINICAL STUDIES (14.2)]. In a placebo-controlled quetiapine fumarate extended-release tablet monotherapy study (8 weeks duration) of children and adolescent patients (10 to 17 years of age) with bipolar depression, in which efficacy was not established, the mean change in fasting glucose levels for quetiapine fumarate extended-release tablet (n = 60) compared to placebo (n = 62) was 1.8 mg/dL versus 1.6 mg/dL. In this study, there were no patients in the quetiapine fumarate extended-release tablet or placebo-treated groups with a baseline normal fasting glucose level (< 100 mg/dL) that had an increase in blood glucose level ≥ 126 mg/dL. There was one patient in the quetiapine fumarate extended-release tablet group with a baseline borderline fasting glucose level (≥ 100 mg/dL and < 126 mg/dL) who had an increase in blood glucose level of > 126 mg/dL compared to zero patients in the placebo group.

    In a placebo-controlled quetiapine fumarate tablet monotherapy study of adolescent patients (13 to 17 years of age) with schizophrenia (6 weeks duration), the mean change in fasting glucose levels for quetiapine fumarate tablet (n=138) compared to placebo (n=67) was -0.75 mg/dL versus -1.70 mg/dL. In a placebo-controlled quetiapine fumarate tablet monotherapy study of children and adolescent patients (10 to 17 years of age) with bipolar mania (3 weeks duration), the mean change in fasting glucose level for quetiapine fumarate tablet (n=170) compared to placebo (n=81) was 3.62 mg/dL versus -1.17 mg/dL. No patient in either study with a baseline normal fasting glucose level (<100 mg/dL) or a baseline borderline fasting glucose level (≥100 mg/dL and <126 mg/dL) had a blood glucose level of ≥126 mg/dL.

    In quetiapine fumarate tablet clinical trials for schizophrenia, the percentage of patients with shifts in cholesterol and triglycerides from baseline to clinically significant levels were 18% (placebo: 7%) and 22% (placebo: 16%). HDL-cholesterol and LDL-cholesterol parameters were not measured in these studies. In quetiapine fumarate tablet clinical trials for bipolar depression, the following percentage of patients had shifts from baseline to clinically significant levels for the four lipid parameters measured: total cholesterol 9% (placebo: 6%); triglycerides 14% (placebo: 9%); LDL-cholesterol 6% (placebo: 5%) and HDL-cholesterol 14% (placebo: 14%). Lipid parameters were not measured in the bipolar mania studies.

    Children and Adolescents:

    Safety and effectiveness of quetiapine fumarate extended-release tablet is supported by studies of quetiapine fumarate tablet in children and adolescent patients 10 to 17 years of age [see CLINICAL STUDIES (14.1 and 14.2)].

    In a placebo-controlled quetiapine fumarate extended-release tablet monotherapy study (8 weeks duration) of children and adolescent patients (10 to 17 years of age) with bipolar depression, in which efficacy was not established, the percentage of children and adolescents with shifts in total cholesterol (≥200 mg/dL), triglycerides (≥150 mg/dL), LDL-cholesterol (≥ 130 mg/dL) and HDL-cholesterol (≤40 mg/dL) from baseline to clinically significant levels were: total cholesterol 8% (7/83) for quetiapine fumarate extended-release tablet vs. 6% (5/84) for placebo; triglycerides 28% (22/80) for quetiapine fumarate extended-release tablet vs. 9% (7/82) for placebo; LDL-cholesterol 2% (2/86) for quetiapine fumarate extended-release tablet vs. 4% (3/85) for placebo and HDL- cholesterol 20% (13/65) for quetiapine fumarate extended-release tablet vs 15% (11/74) for placebo.

    Table 7 shows the percentage of children and adolescents with shifts in total cholesterol, triglycerides, LDL-cholesterol, and HDL-cholesterol from baseline to clinically significant levels by indication in clinical trials with quetiapine fumarate tablet in adolescents (13 to 17 years) with schizophrenia and in children and adolescents (10 to 17 years) with bipolar mania.

    Children and Adolescents:

    Safety and effectiveness of quetiapine fumarate extended-release tablet is supported by studies of quetiapine fumarate tablet in children and adolescent patients 10 to 17 years of age [see CLINICAL STUDIES (14.1 and 14.2)]. In a clinical trial for quetiapine fumarate extended-release tablet in children and adolescents (10 to 17 years of age) with bipolar depression, in which efficacy was not established, the percentage of patients with weight gain ≥7% of body weight at any time was 15% (14/92) for quetiapine fumarate extended-release tablet vs. 10% (10/100) for placebo. The mean change in body weight was 1.4 kg in the quetiapine fumarate extended-release tablet group vs. 0.6 kg in the placebo group.

    Weight gain was greater in patients 10 to 12 years of age compared to patients 13 to 17 years of age. The percentage of patients 10 to 12 years of age with weight gain ≥ 7% at any time was 28% (7/25) for quetiapine fumarate extended-release tablet vs. 0% (0/28) for placebo. The percentage of patients 13 to 17 years of age with weight gain ≥ 7% at any time was 10.4% (7/67) for quetiapine fumarate extended-release tablet vs. 13.9% (10/72) for placebo.

    Table 10 shows the percentage of children and adolescents with weight gain ≥7% of body weight in clinical trials with quetiapine fumarate tablet in adolescents (13 to 17 years) with schizophrenia and in children and adolescents (10 to 17 years) with bipolar mania.

    The mean change in body weight in the schizophrenia trial was 2.0 kg in the quetiapine fumarate tablet group and -0.4 kg in the placebo group and in the bipolar mania trial it was 1.7 kg in the quetiapine fumarate tablet group and 0.4 kg in the placebo group.

    In an open-label study that enrolled patients from the above two pediatric trials, 63% of patients (241/380) completed 26 weeks of therapy with quetiapine fumarate tablet. After 26 weeks of treatment, the mean increase in body weight was 4.4 kg. Forty-five percent of the patients gained ≥ 7% of their body weight, not adjusted for normal growth. In order to adjust for normal growth over 26 weeks, an increase of at least 0.5 standard deviation from baseline in BMI was used as a measure of a clinically significant change; 18.3% of patients on quetiapine fumarate tablet met this criterion after 26 weeks of treatment.

    When treating pediatric patients with quetiapine fumarate tablet for any indication, weight gain should be assessed against that expected for normal growth.

    5.6 Tardive Dyskinesia

    A syndrome of potentially irreversible, involuntary, dyskinetic movements may develop in patients treated with antipsychotic drugs including quetiapine. Although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to rely upon prevalence estimates to predict, at the inception of antipsychotic treatment, 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 developing tardive dyskinesia and the likelihood that it will become irreversible are believed to increase as the duration of treatment and the total cumulative dose of antipsychotic drugs administered to the patient increase. However, the syndrome can develop, although much less commonly, after relatively brief treatment periods at low doses or may even arise after discontinuation of treatment.

    Tardive dyskinesia, may remit, partially or completely, if antipsychotic treatment is withdrawn. Antipsychotic treatment, itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome and thereby may possibly mask the underlying process. The effect that symptomatic suppression has upon the long-term course of the syndrome is unknown.

    Given these considerations, quetiapine fumarate extended-release tablet should be prescribed in a manner that is most likely to minimize the occurrence of tardive dyskinesia. Chronic antipsychotic treatment should generally be reserved for patients who appear to suffer from a chronic illness that (1) is known to respond to antipsychotic drugs, and (2) for whom alternative, equally effective, but potentially less harmful treatments are not available or appropriate. In patients who do require chronic treatment, the smallest dose and the shortest duration of treatment producing a satisfactory clinical response should be sought. The need for continued treatment should be reassessed periodically.

    If signs and symptoms of tardive dyskinesia appear in a patient on quetiapine fumarate extended-release tablet, drug discontinuation should be considered. However, some patients may require treatment with quetiapine despite the presence of the syndrome.

    5.7 Hypotension

    Quetiapine may induce orthostatic hypotension associated with dizziness, tachycardia and, in some patients, syncope, especially during the initial dose-titration period, probably reflecting its α1-adrenergic antagonist properties. Syncope was reported in 0.3% (5/1866) of the patients treated with quetiapine fumarate extended-release tablet across all indications, compared with 0.2% (2/928) on placebo. Syncope was reported in 1% (28/3265) of the patients treated with quetiapine fumarate tablet, compared with 0.2% (2/954) on placebo. Orthostatic hypotension, dizziness, and syncope may lead to falls.

    Quetiapine should be used with particular caution in patients with known cardiovascular disease (history of myocardial infarction or ischemic heart disease, heart failure, or conduction abnormalities), cerebrovascular disease, or conditions which would predispose patients to hypotension (dehydration, hypovolemia, and treatment with antihypertensive medications). If hypotension occurs during titration to the target dose, a return to the previous dose in the titration schedule is appropriate.

    5.8 Falls

    Atypical antipsychotic drugs, including quetiapine fumarate extended-release tablet, 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.

    5.9 Increases in Blood Pressure (Children and Adolescents)

    Safety and effectiveness of quetiapine fumarate extended-release tablet is supported by studies of quetiapine fumarate tablet in children and adolescent patients 10 to 17 years of age [see CLINICAL STUDIES (14.1 and 14.2)].

    In a placebo-controlled quetiapine fumarate extended-release tablet clinical trial (8 weeks duration) in children and adolescents (10 to 17 years of age) with bipolar depression, in which efficacy was not established, the incidence of increases at any time in systolic blood pressure (≥20 mmHg) was 6.5% (6/92) for quetiapine fumarate extended-release tablet and 6.0% (6/100) for placebo; the incidence of increases at any time in diastolic blood pressure (≥10 mmHg) was 46.7% (43/92) for quetiapine fumarate extended-release tablet and 36.0% (36/100) for placebo.

    In placebo-controlled trials in children and adolescents with schizophrenia (13 to 17 years old, 6-week duration) or bipolar mania (10 to 17 years old, 3-week duration), the incidence of increases at any time in systolic blood pressure (≥20 mmHg) was 15.2% (51/335) for quetiapine fumarate tablet and 5.5% (9/163) for placebo; the incidence of increases at any time in diastolic blood pressure (≥10 mmHg) was 40.6% (136/335) for quetiapine fumarate tablet and 24.5% (40/163) for placebo. In the 26-week open-label clinical trial, one child with a reported history of hypertension experienced a hypertensive crisis. Blood pressure in children and adolescents should be measured at the beginning of, and periodically during treatment.

    5.10 Leukopenia, Neutropenia, and Agranulocytosis

    In clinical trials and postmarketing experience, events of leukopenia/neutropenia have been reported temporally related to atypical antipsychotic agents, including quetiapine fumarate. Agranulocytosis has also been reported.

    Agranulocytosis has been reported with quetiapine, including fatal cases and cases in patients without pre-existing risk factors. Neutropenia should be considered in patients presenting with infection, particularly in the absence of obvious predisposing factor(s), or in patients with unexplained fever, and should be managed as clinically appropriate.

    Possible risk factors for leukopenia/neutropenia include pre-existing low white cell count (WBC) and history of drug induced leukopenia/neutropenia. Patients with a pre-existing low WBC or a history of drug induced leukopenia/neutropenia should have their complete blood count (CBC) monitored frequently during the first few months of therapy and should discontinue quetiapine fumarate extended-release tablet at the first sign of a decline in WBC in absence of other causative factors.

    Patients with neutropenia should be carefully monitored for fever or other symptoms or signs of infection and treated promptly if such symptoms or signs occur. Patients with severe neutropenia (absolute neutrophil count <1000/mm3) should discontinue quetiapine fumarate extended-release tablet and have their WBC followed until recovery.

    5.11 Cataracts

    The development of cataracts was observed in association with quetiapine treatment in chronic dog studies [see NONCLINICAL TOXICOLOGY (13.2)]. Lens changes have also been observed in adults, children, and adolescents during long-term quetiapine treatment but a causal relationship to quetiapine use has not been established. Nevertheless, the possibility of lenticular changes cannot be excluded at this time. Therefore, examination of the lens by methods adequate to detect cataract formation, such as slit lamp exam or other appropriately sensitive methods, is recommended at initiation of treatment or shortly thereafter, and at 6-month intervals during chronic treatment.

    5.12 QT Prolongation

    In clinical trials quetiapine was not associated with a persistent increase in QT intervals. However, the QT effect was not systematically evaluated in a thorough QT study. In post marketing experience there were cases reported of QT prolongation in patients who overdosed on quetiapine [see OVERDOSAGE (10.1)], in patients with concomitant illness, and in patients taking medicines known to cause electrolyte imbalance or increase QT interval.

    The use of quetiapine should be avoided in combination with other drugs that are known to prolong QTc including Class 1A antiarrythmics (e.g., quinidine, procainamide) or Class III antiarrythmics (e.g., amiodarone, sotalol), antipsychotic medications (e.g., ziprasidone, chlorpromazine, thioridazine), antibiotics (e.g., gatifloxacin, moxifloxacin), or any other class of medications known to prolong the QTc interval (e.g., pentamidine, levomethadyl acetate, methadone).

    Quetiapine should also be avoided in circumstances that may increase the risk of occurrence of torsade de pointes and/or sudden death including (1) a history of cardiac arrhythmias such as bradycardia; (2) hypokalemia or hypomagnesemia; (3) concomitant use of other drugs that prolong the QTc interval; and (4) presence of congenital prolongation of the QT interval.

    Caution should also be exercised when quetiapine is prescribed in patients with increased risk of QT prolongation (e.g., cardiovascular disease, family history of QT prolongation, the elderly, congestive heart failure, and heart hypertrophy).

    5.13 Seizures

    During short-term clinical trials with quetiapine fumarate extended-release tablet, seizures occurred in 0.05% (1/1866) of patients treated with quetiapine fumarate extended-release tablet across all indications compared to 0.3% (3/928) on placebo. During clinical trials with quetiapine fumarate tablet, seizures occurred in 0.5% (20/3490) of patients treated with quetiapine fumarate tablet compared to 0.2% (2/954) on placebo. As with other antipsychotics, quetiapine fumarate should be used cautiously in patients with a history of seizures or with conditions that potentially lower the seizure threshold, e.g., Alzheimer's dementia. Conditions that lower the seizure threshold may be more prevalent in a population of 65 years or older.

    5.14 Hypothyroidism

    Adults

    Clinical trials with quetiapine demonstrated dose-related decreases in thyroid hormone levels. The reduction in total and free thyroxine (T4) of approximately 20% at the higher end of the therapeutic dose range was maximal in the first six weeks of treatment and maintained without adaptation or progression during more chronic therapy. In nearly all cases, cessation of quetiapine treatment was associated with a reversal of the effects on total and free T4, irrespective of the duration of treatment. The mechanism by which quetiapine effects the thyroid axis is unclear. If there is an effect on the hypothalamic-pituitary axis, measurement of TSH alone may not accurately reflect a patient's thyroid status. Therefore, both TSH and free T4, in addition to clinical assessment, should be measured at baseline and at follow-up.

    In quetiapine fumarate extended-release tablet clinical trials across all indications 1.8% (24/1336) of patients on quetiapine fumarate extended-release tablet versus 0.6% (3/530) on placebo experienced decreased free thyroxine (<0.8 LLN) and 1.6% (21/1346) on quetiapine fumarate extended-release tablet vs. 3.4% (18/534) on placebo experienced increased thyroid stimulating hormone (TSH). About 0.7% (26/3489) of quetiapine fumarate tablet patients did experience TSH increases in monotherapy studies. Some patients with TSH increases needed replacement thyroid treatment.

    In all quetiapine trials, the incidence of shifts in thyroid hormones and TSH were1: decrease in free T4 (<0.8 LLN), 2.0% (357/17513); decrease in total T4 (<0.8 LLN), 4.0% (75/1861); decrease in free T3 (<0.8 LLN), 0.4% (53/13766); decrease in total T3 (<0.8 LLN), 2.0% (26/1312), and increase in TSH (>5 mIU/L), 4.9% (956/19412). In eight patients, where TBG was measured, levels of TBG were unchanged.

    1Based on shifts from normal baseline to potentially clinically important value at anytime post-baseline. Shifts in total T4, free T4, total T3 and free T3 are defined as <0.8 x LLN (pmol/L) and shift in TSH is > 5 mIU/L at any time.

    Table 11 shows the incidence of these shifts in short term placebo-controlled clinical trials.

    Children and Adolescents 

    Safety and effectiveness of quetiapine fumarate extended-release tablet is supported by studies of quetiapine fumarate tablet in children and adolescent patients 10 to 17 years of age [see CLINICAL STUDIES (14.1 and 14.2)].

    In acute placebo-controlled trials in children and adolescent patients with schizophrenia (6-week duration) or bipolar mania (3-week duration), the incidence of shifts at any time for quetiapine fumarate tablet treated patients and placebo-treated patients for elevated TSH was 2.9% (8/280) vs. 0.7% (1/138), respectively, and for decreased total thyroxine was 2.8% (8/289) vs. 0% (0/145), respectively. Of the quetiapine fumarate tablet treated patients with elevated TSH levels, 1 had simultaneous low free T4 level at end of treatment.

    5.15 Hyperprolactinemia

    Adults

    During clinical trials with quetiapine across all indications, the incidence of shifts in prolactin levels to a clinically significant value occurred in 3.6% (158/4416) of patients treated with quetiapine compared to 2.6% (51/1968) on placebo.

    Children and Adolescents

    Safety and effectiveness of quetiapine fumarate extended-release tablet is supported by studies of quetiapine fumarate tablet in children and adolescent patients 10 to 17 years of age [see CLINICAL STUDIES (14.1 and 14.2)]. In acute placebo-controlled trials in children and adolescent patients with bipolar mania (3-week duration) or schizophrenia (6-week duration), the incidence of shifts in prolactin levels to a value (>20 µg/L males; > 26 µg/L females at any time) was 13.4% (18/134) for quetiapine fumarate tablet compared to 4% (3/75) for placebo in males and 8.7% (9/104) for quetiapine fumarate tablet compared to 0% (0/39) for placebo in females.

    Like other drugs that antagonize dopamine D2 receptors, quetiapine fumarate extended-release tablet elevates prolactin levels in some patients and the elevation may persist during chronic administration. Hyperprolactinemia, regardless of etiology, may suppress hypothalamic GnRH, resulting in reduced pituitary gonadotrophin secretion. This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds. Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male subjects.

    Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin dependent in vitro, a factor of potential importance if the prescription of these drugs is considered in a patient with previously detected breast cancer. As is common with compounds which increase prolactin release, mammary gland, and pancreatic islet cell neoplasia (mammary adenocarcinomas, pituitary, and pancreatic adenomas) was observed in carcinogenicity studies conducted in mice and rats. Neither clinical studies nor epidemiologic studies conducted to date have shown an association between chronic administration of this class of drugs and tumorigenesis in humans, but the available evidence is too limited to be conclusive [see NONCLINICAL TOXICOLOGY (13.1)].

    5.16 Potential for Cognitive and Motor Impairment

    Somnolence was a commonly reported adverse reaction reported in patients treated with quetiapine especially during the 3-day period of initial dose titration. In schizophrenia trials, somnolence was reported in 24.7% (235/951) of patients on quetiapine fumarate extended-release tablet compared to 10.3% (33/319) of placebo patients. In a bipolar depression clinical trial, somnolence was reported in 51.8% (71/137) of patients on quetiapine fumarate extended-release tablet compared to 12.9% (18/140) of placebo patients. In a clinical trial for bipolar mania, somnolence was reported in 50.3% (76/151) of patients on quetiapine fumarate extended-release tablet compared to 11.9% (19/160) of placebo patients. Since quetiapine has the potential to impair judgment, thinking, or motor skills, patients should be cautioned about performing activities requiring mental alertness, such as operating a motor vehicle (including automobiles) or operating hazardous machinery until they are reasonably certain that quetiapine therapy does not affect them adversely. Somnolence may lead to falls.

    In short-term adjunctive therapy trials for MDD, somnolence was reported in 40% (252/627) of patients on quetiapine fumarate extended-release tablet respectively compared to 9% (27/309) of placebo patients. Somnolence was dose-related in these trials (37% (117/315) and 43% (135/312) for the 150 mg and 300 mg groups, respectively).

    5.17 Body Temperature Regulation

    Disruption of the body's ability to reduce core body temperature has been attributed to antipsychotic agents. Appropriate care is advised when prescribing quetiapine fumarate extended-release tablet for patients who will be experiencing conditions which may contribute to an elevation in core body temperature, e.g., exercising strenuously, exposure to extreme heat, receiving concomitant medication with anticholinergic activity, or being subject to dehydration.

    5.18 Dysphagia

    Esophageal dysmotility and aspiration have been associated with antipsychotic drug use. Aspiration pneumonia is a common cause of morbidity and mortality in elderly patients, in particular those with advanced Alzheimer's dementia. Quetiapine fumarate extended-release tablet and other antipsychotic drugs should be used cautiously in patients at risk for aspiration pneumonia.

    5.19 Discontinuation Syndrome

    Acute withdrawal symptoms, such as insomnia, nausea and vomiting have been described after abrupt cessation of atypical antipsychotic drugs, including quetiapine fumarate. In short-term placebo-controlled, monotherapy clinical trials with quetiapine fumarate extended-release tablet that included a discontinuation phase which evaluated discontinuation symptoms, the aggregated incidence of patients experiencing one or more discontinuation symptoms after abrupt cessation was 12.1% (241/1993) for quetiapine fumarate extended-release tablet and 6.7% (71/1065) for placebo. The incidence of the individual adverse reactions (i.e., insomnia, nausea, headache, diarrhea, vomiting, dizziness and irritability) did not exceed 5.3% in any treatment group and usually resolved after 1 week post-discontinuation. Gradual dose reduction is advised [see USE IN SPECIFIC POPULATIONS (8.1)].

    5.20 Anticholinergic (antimuscarinic) Effects

    Norquetiapine, an active metabolite of quetiapine, has moderate to strong affinity for several muscarinic receptor subtypes. This contributes to anticholinergic adverse reactions when quetiapine fumarate extended-release tablet is used at therapeutic doses, taken concomitantly with other anticholinergic medications, or taken in overdose. Quetiapine fumarate extended-release tablet should be used with caution in patients receiving medications having anticholinergic (antimuscarinic) effects [see OVERDOSAGE (10.1) and CLINICAL PHARMACOLOGY (12.1)].

    Constipation was a commonly reported adverse event in patients treated with quetiapine and represents a risk factor for intestinal obstruction. Intestinal obstruction has been reported with quetiapine, including fatal reports in patients who were receiving multiple concomitant medications that decrease intestinal motility.

    Quetiapine fumarate extended-release tablet should be used with caution in patients with a current diagnosis or prior history of urinary retention, clinically significant prostatic hypertrophy, or constipation, or increased intraocular pressure.

    6.1 Clinical Studies 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 clinical practice.

    Adults

    The information below is derived from a clinical trial database for quetiapine fumarate extended-release tablet consisting of approximately 3400 patients exposed to quetiapine fumarate extended-release tablet for the treatment of Schizophrenia, Bipolar Disorder, and Major Depressive Disorder in placebo-controlled trials. This experience corresponds to approximately 1020.1 patient-years. Adverse reactions were assessed by collecting adverse reactions, results of physical examinations, vital signs, body weights, laboratory analyses and ECG results.

    The stated frequencies of adverse reactions represent the proportion of individuals who experienced, at least once, an adverse reaction of the type listed.

    Adverse Reactions Associated with Discontinuation of Treatment in Short-Term, Placebo-Controlled Trials

    Schizophrenia:

    There were no adverse reactions leading to discontinuation that occurred at an incidence of ≥ 2% for quetiapine fumarate extended-release tablet in schizophrenia trials.

    Bipolar I Disorder, Manic or Mixed Episodes:

    There were no adverse reactions leading to discontinuation that occurred at an incidence of ≥ 2% for quetiapine fumarate extended-release tablet in the bipolar mania trial.

    Bipolar Disorder, Depressive Episode:

    In a single clinical trial in patients with bipolar depression, 14% (19/137) of patients on quetiapine fumarate extended-release tablet discontinued due to an adverse reaction compared to 4% (5/140) on placebo. Somnolence2 was the only adverse reaction leading to discontinuation that occurred at an incidence of ≥ 2% in quetiapine fumarate extended-release tablet in the bipolar depression trial.

    MDD, Adjunctive Therapy:

    In adjunctive therapy clinical trials in patients with MDD, 12.1% (76/627) of patients on quetiapine fumarate extended-release tablet discontinued due to adverse reaction compared to 1.9% (6/309) on placebo. Somnolence2 was the only adverse reaction leading to discontinuation that occurred at an incidence of ≥ 2% in quetiapine fumarate extended-release tablet in MDD trials.

    Commonly Observed Adverse Reactions in Short-Term, Placebo-Controlled Trials

    In short-term placebo-controlled studies for schizophrenia the most commonly observed adverse reactions associated with the use of quetiapine fumarate extended-release tablet (incidence of 5% or greater) and observed at a rate on quetiapine fumarate extended-release tablet at least twice that of placebo were somnolence (25%), dry mouth (12%), dizziness (10%), and dyspepsia (5%).

    Adverse Reactions occurring at an Incidence of 2% or more Among quetiapine fumarate extended-release tablet Treated Patients in Short-Term, Placebo-Controlled Trials

    Adverse Reactions In Clinical Trials With Quetiapine And Not Listed Elsewhere In The Label

    Pyrexia, nightmares, peripheral edema, dyspnea, palpitations, rhinitis, eosinophilia, hypersensitivity, elevations in gamma-GT levels, and elevations in serum creatine phosphokinase (not associated with NMS), somnambulism (and other related events), hypothermia, decreased platelets, galactorrhea, bradycardia (which may occur at or near initiation of treatment and be associated with hypotension and/ or syncope), and priapism.

    Extrapyramidal Symptoms (EPS)

    Dystonia:

    Class Effect

    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.

    Four methods were used to measure EPS: (1) Simpson-Angus total score (mean change from baseline) which evaluates Parkinsonism and akathisia, (2) Barnes Akathisia Rating Scale (BARS) Global Assessment Score, (3) incidence of spontaneous complaints of EPS (akathisia, akinesia, cogwheel rigidity, extrapyramidal syndrome, hypertonia, hypokinesia, neck rigidity, and tremor), and (4) use of anticholinergic medications to treat EPS.

    Adults

    In placebo-controlled clinical trials with quetiapine, utilizing doses up to 800 mg per day, the incidence of any adverse reactions related to EPS ranged from 8% to 11% for quetiapine and 4% to 11% for placebo.

    In three-arm placebo-controlled clinical trials for the treatment of schizophrenia, utilizing doses between 300 mg and 800 mg of quetiapine fumarate extended-release tablet, the incidence of any adverse reactions related to EPS was 8% for quetiapine fumarate extended-release tablet and 8% for quetiapine fumarate tablet (without evidence of being dose related), and 5% in the placebo group. In these studies, the incidence of the individual adverse reactions (akathisia, extrapyramidal disorder, tremor, dyskinesia, dystonia, restlessness, and muscle rigidity) was generally low and did not exceed 3% for any treatment group.

    At the end of treatment, the mean change from baseline in SAS total score and BARS Global Assessment score was similar across the treatment groups. The use of concomitant anticholinergic medications was infrequent and similar across the treatment groups. The incidence of extrapyramidal symptoms was consistent with that seen with the profile of quetiapine fumarate tablet in schizophrenia patients.

    In Tables 16 to 19, dystonic event included nuchal rigidity, hypertonia, dystonia, muscle rigidity, oculogyration; parkinsonism included cogwheel rigidity, tremor, drooling, hypokinesia; akathisia included akathisia, psychomotor agitation; dyskinetic event included tardive dyskinesia, dyskinesia, choreoathetosis; and other extrapyramidal event included restlessness, extrapyramidal disorder, movement disorder.

    Children and Adolescents

    The information below is derived from a clinical trial database for quetiapine fumarate tablet consisting of over 1000 pediatric patients. This database includes 677 adolescents (13 to 17 years old) exposed to quetiapine fumarate tablet for the treatment of schizophrenia and 393 children and adolescents (10 to 17 years old) exposed to quetiapine fumarate tablet for the treatment of acute bipolar mania.

    Adverse Reactions Associated with Discontinuation of Treatment in Short-Term, Placebo-Controlled Trials

    Schizophrenia:

    The incidence of discontinuation due to adverse reactions for quetiapine-treated and placebo-treated patients was 8.2% and 2.7%, respectively. The adverse reaction leading to discontinuation in 2% or more of patients on quetiapine and at a greater incidence than placebo was somnolence (2.7% and 0% for placebo).

    Bipolar I Mania: 

    The incidence of discontinuation due to adverse reactions for quetiapine-treated and placebo-treated patients was 11.4% and 4.4%, respectively. The adverse reactions leading to discontinuation in 2% or more of patients on quetiapine fumarate tablet and at a greater incidence than placebo were somnolence (4.1% vs. 1.1%) and fatigue (2.1% vs. 0%).

    Commonly Observed Adverse Reactions in Short-Term, Placebo-Controlled Trials

    In an acute (8-week) quetiapine fumarate extended-release tablet trial in children and adolescents (10 to 17 years of age) with bipolar depression, in which efficacy was not established, the most commonly observed adverse reactions associated with the use of quetiapine fumarate extended-release tablet (incidence of 5% or greater and at least twice that for placebo) were: dizziness (7%), diarrhea (5%), fatigue (5%) and nausea (5%).

    In therapy for schizophrenia (up to 6 weeks), the most commonly observed adverse reactions associated with the use of quetiapine in adolescents (incidence of 5% or greater and quetiapine incidence at least twice that for placebo) were somnolence (34%), dizziness (12%), dry mouth (7%), tachycardia (7%).

    In bipolar mania therapy (up to 3 weeks) the most commonly observed adverse reactions associated with the use of quetiapine in children and adolescents (incidence of 5% or greater and quetiapine incidence at least twice that for placebo) were somnolence (53%), dizziness (18%), fatigue (11%), increased appetite (9%), nausea (8%), vomiting (8%), tachycardia (7%), dry mouth (7%), and weight increased (6%).

    Adverse Reactions Occurring at an Incidence of ≥ 2% among Quetiapine Fumarate Tablet Treated Patients in Short-Term, Placebo-Controlled Trials

    Schizophrenia (Adolescents, 13 to 17 years old):

    The following findings were based on a 6-week placebo-controlled trial in which quetiapine was administered in either doses of 400 or 800 mg/day.

    Table 20 enumerates the incidence, rounded to the nearest percent, of adverse reactions that occurred during therapy (up to 6 weeks) of schizophrenia in 2% or more of patients treated with quetiapine fumarate tablet (doses of 400 or 800 mg/day) where the incidence in patients treated with quetiapine fumarate tablet was greater than the incidence in placebo-treated patients.

    Adverse reactions that were potentially dose-related with higher frequency in the 800 mg group compared to the 400 mg group included dizziness (8% vs. 15%), dry mouth (4% vs. 10%), and tachycardia (6% vs. 11%).

    Extrapyramidal Symptoms

    Safety and effectiveness of quetiapine fumarate extended-release tablet is supported by studies of quetiapine fumarate tablet in children and adolescent patients 10 to 17 years of age [see CLINICAL STUDIES (14.1 and 14.2)].

    In a short-term placebo-controlled quetiapine fumarate extended-release tablet monotherapy trial in children and adolescent patients (10 to 17 years of age) with bipolar depression (8-week duration), in which efficacy was not established, the aggregated incidence of extrapyramidal symptoms was 1.1% (1/92) for quetiapine fumarate extended-release tablet and 0% (0/100) for placebo.

    In a short-term placebo-controlled quetiapine fumarate tablet monotherapy trial in adolescent patients (13 to 17 years of age) with schizophrenia (6-week duration), the aggregated incidence of extrapyramidal symptoms was 12.9% (19/147) for quetiapine fumarate tablet and 5.3% (4/75) for placebo, though the incidence of the individual adverse reactions (e.g., akathisia, tremor, extrapyramidal disorder, hypokinesia, restlessness, psychomotor hyperactivity, muscle rigidity, dyskinesia) did not exceed 4.1% in any treatment group. In a short-term placebo-controlled quetiapine fumarate tablet monotherapy trial in children and adolescent patients (10 to 17 years of age) with bipolar mania (3-week duration), the aggregated incidence of extrapyramidal symptoms was 3.6% (7/193) for quetiapine fumarate tablet and 1.1% (1/90) for placebo.

    In Tables 22 and 23, dystonic events included nuchal rigidity, hypertonia, dystonia, and muscle rigidity; parkinsonism included cogwheel rigidity and tremor; akathisia included akathisia only; dyskinetic event included tardive dyskinesia, dyskinesia and choreoathetosis; and other extrapyramidal event included restlessness and extrapyramidal disorder.

    Table 22 below presents a listing of patients with adverse reactions associated with EPS in the short-term placebo-controlled quetiapine tablet monotherapy trial in adolescent patients with schizophrenia (6-week duration).

    Laboratory, ECG and Vital Sign Changes Observed in Clinical Studies

    Laboratory Changes:

    Neutrophil Counts

    Adults:

    In three-arm quetiapine fumarate extended-release tablet placebo-controlled monotherapy clinical trials, among patients with a baseline neutrophil count ≥ 1.5 x 109/L, the incidence of at least one occurrence of neutrophil count <1.5 x 109/L was 1.5% in patients treated with quetiapine fumarate extended-release tablet and 1.5% for quetiapine fumarate tablet, compared to 0.8% in placebo-treated patients.

    In placebo-controlled monotherapy clinical trials involving 3368 patients on quetiapine fumarate and 1515 on placebo, the incidence of at least one occurrence of neutrophil count <1.0 x 109/L among patients with a normal baseline neutrophil count and at least one available follow up laboratory measurement was 0.3% (10/2967) in patients treated with quetiapine, compared to 0.1% (2/1349) in patients treated with placebo [see WARNINGS AND PRECAUTIONS (5.10)].

    Transaminase Elevations:

    Adults:

    Asymptomatic, transient and reversible elevations in serum transaminases (primarily ALT) have been reported. The proportions of adult patients with transaminase elevations of >3 times the upper limits of the normal reference range in a pool of placebo-controlled trials ranged between 1% and 2% for quetiapine fumarate extended-release tablet compared to 2% for placebo. In schizophrenia trials in adults, the proportions of patients with transaminase elevations of >3 times the upper limits of the normal reference range in a pool of 3- to 6-week placebo-controlled trials were approximately 6% (29/483) for quetiapine fumarate tablet compared to 1% (3/194) for placebo. These hepatic enzyme elevations usually occurred within the first 3 weeks of drug treatment and promptly returned to pre-study levels with ongoing treatment with quetiapine.

    Decreased Hemoglobin:

    Adults

    In short-term placebo-controlled trials, decreases in hemoglobin to ≤ 13 g/dL males, ≤ 12 g/dL females on at least one occasion occurred in 8.3% (594/7155) of quetiapine-treated patients compared to 6.2%(219/3536) of patients treated with placebo. In a database of controlled and uncontrolled clinical trials, decreases in hemoglobin to ≤ 13 g/dL males, ≤ 12 g/dL females on at least one occasion occurred in 11% (2277/20729) of quetiapine-treated patients.

    Interference with Urine Drug Screens

    There have been literature reports suggesting false positive results in urine enzyme immunoassays for methadone and tricyclic antidepressants in patients who have taken quetiapine. Caution should be exercised in the interpretation of positive urine drug screen results for these drugs, and confirmation by alternative analytical technique (e.g. chromatographic methods) should be considered.

    ECG Changes:

    Adults

    2.5% of quetiapine fumarate extended-release tablet patients, and 2.3% of placebo patients, had tachycardia (>120 bpm) at any time during the trials. Quetiapine fumarate extended-release tablet was associated with a mean increase in heart rate, assessed by ECG, of 6.3 beats per minute compared to a mean increase of 0.4 beats per minute for placebo. This is consistent with the rates for quetiapine fumarate tablet. The incidence of adverse reactions of tachycardia was 1.9% for quetiapine fumarate extended-release tablet compared to 0.5% for placebo. Quetiapine fumarate tablet use was associated with a mean increase in heart rate, assessed by ECG, of 7 beats per minute compared to a mean increase of 1 beat per minute among placebo patients. The slight tendency for tachycardia may be related to quetiapine's potential for inducing orthostatic changes [see WARNINGS AND PRECAUTIONS (5.7)].

    Children and Adolescents

    Safety and effectiveness of quetiapine fumarate extended-release tablet is supported by studies of quetiapine fumarate tablet in children and adolescent patients 10 to 17 years of age [(see CLINICAL STUDIES (14.1 and 14.2)].

    In an acute (8-week) quetiapine fumarate extended-release tablet trial in children and adolescents (10 to 17 years of age) with bipolar depression, in which efficacy was not established, increases in heart rate (> 110 bpm 10 to 12 years and 13 to 17 years) occurred in 0% of patients receiving quetiapine fumarate extended-release tablet and 1.2% of patients receiving placebo. Mean increases in heart rate were 3.4 bpm for quetiapine fumarate extended-release tablet, compared to 0.3 bpm in the placebo group [see WARNINGS AND PRECAUTIONS (5.7)].

    In the acute (6-week) quetiapine fumarate tablet schizophrenia trial in adolescents (13 to 17 years of age), increases in heart rate (> 110 bpm) occurred in 5.2% of patients receiving quetiapine fumarate tablet 400 mg and 8.5% of patients receiving quetiapine fumarate tablet 800 mg compared to 0% of patients receiving placebo. Mean increases in heart rate were 3.8 bpm and 11.2 bpm for quetiapine fumarate tablet 400 mg and 800 mg groups, respectively, compared to a decrease of 3.3 bpm in the placebo group [see WARNINGS AND PRECAUTIONS (5.7)].

    In the acute (3-week) quetiapine fumarate tablet bipolar mania trial in children and adolescents (10 to 17 years of age), increases in heart rate (> 110 bpm) occurred in 1.1% of patients receiving quetiapine fumarate tablet 400 mg and 4.7% of patients receiving quetiapine fumarate tablet 600 mg compared to 0% of patients receiving placebo. Mean increases in heart rate were 12.8 bpm and 13.4 bpm for quetiapine fumarate tablet 400 mg and 600 mg groups, respectively, compared to a decrease of 1.7 bpm in the placebo group [see WARNINGS AND PRECAUTIONS (5.7)].

    6.2 Postmarketing Experience

    The following adverse reactions were identified during post approval use of quetiapine fumarate tablet. 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.

    Adverse reactions reported since market introduction which were temporally related to quetiapine therapy include anaphylactic reaction, cardiomyopathy, drug reaction with eosinophilia and systemic symptoms (DRESS), hyponatremia, myocarditis, nocturnal enuresis, pancreatitis, retrograde amnesia, rhabdomyolysis, syndrome of inappropriate antidiuretic hormone secretion (SIADH), Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) , decreased platelet count, serious liver reactions (including hepatitis, liver necrosis, and hepatic failure), agranulocytosis, intestinal obstruction, ileus, colon ischemia, sleep apnea, urinary retention and acute generalized exanthematous pustulosis (AGEP).

  • 7 DRUG INTERACTIONS

    7.1 Effect of Other Drugs on Quetiapine

    The risks of using quetiapine fumarate extended-release tablet in combination with other drugs have not been extensively evaluated in systematic studies. Given the primary CNS effects of quetiapine fumarate extended-release tablet, caution should be used when it is taken in combination with other centrally acting drugs. Quetiapine potentiated the cognitive and motor effects of alcohol in a clinical trial in subjects with selected psychotic disorders, and alcoholic beverages should be limited while taking quetiapine.

    Quetiapine exposure is increased by the prototype CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, indinavir, ritonavir, nefazodone, etc.). and decreased by the prototype of CYP3A4 inducers (e.g, phenytoin, carbamazepine, rifampin, avasimibe, St. John's wort etc). Dose adjustment of quetiapine will be necessary if it is co-administered with potent CYP3A4 inducers or inhibitors.

    CYP3A4 inhibitors

    Coadministration of ketoconazole, a potent inhibitor of cytochrome CYP3A4, resulted in significant increase in quetiapine exposure. The dose should be reduced to one sixth of the original dose in patients coadministered with a strong CYP3A4 inhibitor [see DOSAGE AND ADMINISTRATION (2.5) and CLINICAL PHARMACOLOGY (12.3)].

    CYP3A4 inducers

    Coadministration of quetiapine and phenytoin, a CYP3A4 inducer increased the mean oral clearance of quetiapine by 5-fold. Increased doses of quetiapine fumarate extended-release tablet up to 5 fold may be required to maintain control of symptoms of schizophrenia in patients receiving quetiapine and phenytoin, or other known potent CYP3A4 inducers [see DOSAGE AND ADMINISTRATION (2.6) and CLINICAL PHARMACOLOGY (12.3)]. When the CYP3A4 inducer is discontinued, the dose of quetiapine fumarate extended-release tablet should be reduced to the original level within 7 to 14 days [see DOSAGE AND ADMINISTRATION (2.6)].

    The potential effects of several concomitant medications on quetiapine pharmacokinetics were studied.

    7.2 Effect of Quetiapine on Other Drugs

    Because of its potential for inducing hypotension, quetiapine fumarate extended-release tablet may enhance the effects of certain antihypertensive agents.

    Quetiapine fumarate extended-release tablet may antagonize the effects of levodopa and dopamine agonists.

    There are no clinically relevant pharmacokinetic interactions of quetiapine fumarate tablet on other drugs based on the CYP pathway. Quetiapine fumarate tablet and its metabolites are non-inhibitors of major metabolizing CYP's (1A2, 2C9, 2C19, 2D6 and 3A4).

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Pregnancy Exposure Registry

    There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including quetiapine fumarate extended-release tablet, during pregnancy. Healthcare providers are encouraged to register patients by contacting the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or online at http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/.

    Risk Summary:

    Neonates exposed to antipsychotic drugs, including quetiapine fumarate extended-release tablet, during the third trimester are at risk for extrapyramidal and/or withdrawal symptoms following delivery (see CLINICAL CONSIDERATIONS). Overall available data from published epidemiologic studies of pregnant women exposed to quetiapine have not established a drug-associated risk     of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data). There are risks to the mother associated with untreated schizophrenia, bipolar I, or major depressive disorder, and with exposure to antipsychotics, including, quetiapine fumarate extended-release tablet during pregnancy (see CLINICAL CONSIDERATIONS). In animal studies, embryo-fetal toxicity occurred including delays in skeletal ossification at approximately 1 and 2 times the maximum recommended human dose (MRHD) of 800 mg/day in both rats and rabbits, and an increased incidence of carpal/tarsal flexure (minor soft tissue anomaly) in rabbit fetuses at approximately 2 times the MRHD. In addition, fetal weights were decreased in both species. Maternal toxicity (observed as decreased body weights and/or death) occurred at 2 times the MRHD in rats and approximately 1 to 2 times the MRHD in rabbits.

    The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

    Clinical Considerations

    Disease-associated maternal and/or fetal risk

    There is a risk to the mother from untreated schizophrenia, or bipolar I disorder, including increased risk of relapse, hospitalization, and suicide. Schizophrenia and bipolar I disorder are associated with increased adverse perinatal outcomes, including preterm birth. It is not known if this is a direct result of the illness or other comorbid factors.

    A prospective, longitudinal study followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy. The women who discontinued antidepressants during pregnancy were more likely to experience a relapse of major depression than women who continued antidepressants. Consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum.

    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 who were exposed to antipsychotic drugs, including quetiapine fumarate extended-release tablet, during the third trimester of pregnancy. These symptoms varied in severity. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization.

    Data

    Human Data

    Published data from observational studies, birth registries, and case reports on the use of atypical antipsychotics during pregnancy do not report a clear association with antipsychotics and major birth defects. A retrospective cohort study from a Medicaid database of 9258 women exposed to antipsychotics during pregnancy did not indicate an overall increased risk of major birth defects.

    Animal Data:

    When pregnant rats and rabbits were exposed to quetiapine during organogenesis, there was no teratogenic effect in fetuses. Doses were 25, 50 and 200 mg/kg in rats and 25, 50 and 100 mg/kg in rabbits which are approximately 0.3, 0.6 and 2-times (rats) and 0.6, 1 and 2-times (rabbits) the MRHD, for schizophrenia of 800 mg/day based on mg/m2 body surface area. However, there was evidence of embryo-fetal toxicity including delays in skeletal ossification at approximately 1 and 2 times the MRHD of 800 mg/day in both rats and rabbits and an increased incidence of carpal/tarsal flexure (minor soft tissue anomaly) in rabbit fetuses at approximately 2 times the MRHD. In addition, fetal weights were decreased in both species. Maternal toxicity (observed as decreased body weights and/or death) occurred at 2 times the MRHD in rats and at approximately 1 to 2 times the MRHD (all doses tested) in rabbits.

    In a peri/postnatal reproductive study in rats, no drug-related effects were observed when pregnant dams were treated with quetiapine at doses 0.01, 0.1, and 0.2 times the MRHD of 800 mg/day based on mg/m2body surface area. However, in a preliminary peri/postnatal study, there were increases in fetal and pup death, and decreases in mean litter weight at 3 times the MRHD.

    8.2 Lactation

    Risk Summary

    Limited data from published literature report the presence of quetiapine in human breast milk at relative infant dose of <1% of the maternal weight-adjusted dosage. There are no consistent adverse events that have been reported in infants exposed to quetiapine through breast milk. There is no information on the effects of quetiapine on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for quetiapine fumarate extended-release tablet and any potential adverse effects on the breastfed child from quetiapine fumarate extended-release tablet or from the mother's underlying condition.

    8.3 Females and Males of Reproductive Potential

    Infertility

    Females

    Based on the pharmacologic action of quetiapine (D2 antagonism), treatment with quetiapine fumarate extended-release tablet may result in an increase in serum prolactin levels, which may lead to a reversible reduction in fertility in females of reproductive potential [see WARNINGS AND PRECAUTIONS (5.15)].

    8.4 Pediatric Use

    Safety and effectiveness of quetiapine fumarate extended-release tablet is supported by studies of quetiapine fumarate tablet for schizophrenia in adolescent patients 13 to 17 years of age and in bipolar mania in children and adolescent patients 10 to 17 years of age [see CLINICAL STUDIES (14.1 and 14.2)].

    In general, the adverse reactions observed in children and adolescents during the clinical trials with quetiapine fumarate tablet were similar to those in the adult population with few exceptions. Increases in systolic and diastolic blood pressure occurred in children and adolescents and did not occur in adults. Orthostatic hypotension occurred more frequently in adults (4 to 7%) compared to children and adolescents (< 1%) [see WARNINGS AND PRECAUTIONS (5.7) and ADVERSE REACTIONS (6.1)].

    Bipolar Depression

    The effectiveness of quetiapine fumarate extended-release tablet for the treatment of bipolar depression in patients under the age of 18 years has not been established. One 8-week trial was conducted to evaluate the safety and efficacy of quetiapine fumarate extended-release tablet in the treatment of bipolar depression in pediatric patients 10 to 17 years of age. The primary objective of the study was to evaluate whether quetiapine extended-release tablet at a dose of 150 to 300 mg/day demonstrated superior efficacy (as measured by change in CDRS-R total score from baseline to end of 8 weeks) compared to placebo in children and adolescents 10 to 17 years of age with bipolar depression. A total of 193 patients with bipolar depression were randomized to placebo or quetiapine fumarate extended-release tablet. The primary results of this study did not show a difference between quetiapine fumarate extended-release tablet and placebo in decreasing depression symptoms in children and adolescents with bipolar disorder. In this study, patients treated with quetiapine fumarate extended-release tablet exhibited metabolic changes, weight gain, increases in blood pressure and increases in heart rate [see WARNINGS AND PRECAUTIONS (5.5, 5.9) and ADVERSE REACTIONS (6.1)].

    Some differences in the pharmacokinetics of quetiapine were noted between children/adolescents (10 to 17 years of age) and adults. When adjusted for weight, the AUC and Cmax of quetiapine were 41% and 39% lower, respectively, in children and adolescents compared to adults. The pharmacokinetics of the active metabolite, norquetiapine, were similar between children/adolescents and adults after adjusting for weight [see CLINICAL PHARMACOLOGY (12.3)].

    Schizophrenia

    The efficacy and safety of quetiapine fumarate extended-release tablet in the treatment of schizophrenia in adolescents aged 13 to 17 years is supported by one 6-week, double-blind, placebo-controlled trial with quetiapine fumarate tablet [see INDICATIONS AND USAGE (1.1), DOSAGE AND ADMINISTRATION (2.2), ADVERSE REACTIONS (6.1), and CLINICAL STUDIES (14.1)].

    Safety and effectiveness of quetiapine fumarate extended-release tablet in pediatric patients less than 13 years of age with schizophrenia have not been established.

    The safety and effectiveness of quetiapine fumarate extended-release tablet in the maintenance treatment of schizophrenia has not been established in patients less than 18 years of age.

    Bipolar Mania

    The efficacy and safety of quetiapine fumarate extended-release tablet in the treatment of bipolar mania in children and adolescents ages 10 to 17 years is supported by one 3-week, double-blind, placebo controlled trial with quetiapine fumarate tablet [see INDICATIONS AND USAGE (1.2), DOSAGE AND ADMINISTRATION (2.2), ADVERSE REACTIONS (6.1), and CLINICAL STUDIES (14.2)].

    Safety and effectiveness of quetiapine fumarate extended-release tablet in pediatric patients less than 10 years of age with bipolar mania have not been established.

    The safety and effectiveness of quetiapine fumarate extended-release tablet in the maintenance treatment of bipolar disorder has not been established in patients less than 18 years of age.

    8.5 Geriatric Use

    Sixty-eight patients in clinical studies with quetiapine fumarate extended-release tablet were 65 years of age or over. In general, there was no indication of any different tolerability of quetiapine fumarate extended-release tablet in the elderly compared to younger adults. Nevertheless, the presence of factors that might decrease pharmacokinetic clearance, increase the pharmacodynamic response to quetiapine fumarate extended-release tablet, or cause poorer tolerance or orthostasis, should lead to consideration of a lower starting dose, slower titration, and careful monitoring during the initial dosing period in the elderly. The mean plasma clearance of quetiapine was reduced by 30% to 50% in elderly patients when compared to younger patients [see DOSAGE AND ADMINISTRATION (2.3) and CLINICAL PHARMACOLOGY (12.3)].

    8.6 Renal Impairment

    Clinical experience with quetiapine fumarate extended-release tablet in patients with renal impairment is limited [see CLINICAL PHARMACOLOGY (12.3)].

    8.7 Hepatic Impairment

    Since quetiapine is extensively metabolized by the liver, higher plasma levels are expected in patients with hepatic impairment. In this population, a low starting dose of 50 mg/day is recommended and the dose may be increased in increments of 50 mg/day [see DOSAGE AND ADMINISTRATION (2.4) and CLINICAL PHARMACOLOGY (12.3)].

  • 9 DRUG ABUSE AND DEPENDENCE

    9.1 Controlled Substance

    Quetiapine fumarate is not a controlled substance.

    9.2 Abuse

    Quetiapine fumarate extended-release tablet has not been systematically studied in animals or humans for its potential for abuse, tolerance or physical dependence. While the clinical trials did not reveal any tendency for any drug-seeking behavior, these observations were not systematic and it is not possible to predict on the basis of this limited experience the extent to which a CNS-active drug will be misused, diverted, and/or abused once marketed. Consequently, patients should be evaluated carefully for a history of drug abuse, and such patients should be observed closely for signs of misuse or abuse of quetiapine fumarate extended-release tablet (e.g., development of tolerance, increases in dose, drug-seeking behavior).

  • 10 OVERDOSAGE

    10.1 Human Experience

    In clinical trials, survival has been reported in acute overdoses of up to 30 grams of quetiapine. Most patients who overdosed experienced no adverse reactions or recovered fully from the reported events. Death has been reported in a clinical trial following an overdose of 13.6 grams of quetiapine alone. In general, reported signs and symptoms were those resulting from an exaggeration of the drug's known pharmacological effects, i.e., drowsiness, sedation, tachycardia, hypotension, and anticholinergic toxicity including coma and delirium. Patients with pre-existing severe cardiovascular disease may be at an increased risk of the effects of overdose [see WARNINGS AND PRECAUTIONS (5.12)]. One case, involving an estimated overdose of 9600 mg, was associated with hypokalemia and first degree heart block. In post-marketing experience, there were cases reported of QT prolongation with overdose.

    10.2 Management of Overdosage

    Establish and maintain an airway and ensure adequate oxygenation and ventilation. Cardiovascular monitoring should commence immediately and should include continuous electrocardiographic monitoring to detect possible arrhythmias.

    Appropriate supportive measures are the mainstay of management. For the most up-to-date information on the management of quetiapine fumarate extended-release tablet overdosage, contact a certified Regional Poison Control Center (1-800-222-1222).

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    The mechanism of action of quetiapine fumarate extended-release tablet in the listed indications is unclear. However, the efficacy of quetiapine in these indications could be mediated through a combination of dopamine type 2 (D2) and serotonin type 2A (5HT2A) antagonism. The active metabolite, N-desalkyl quetiapine (norquetiapine), has similar activity at D2, but greater activity at 5HT2A receptors, than the parent drug (quetiapine).

    12.2 Pharmacodynamics

    Quetiapine and its metabolite norquetiapine have affinity for multiple neurotransmitter receptors with norquetiapine binding with higher affinity than quetiapine in general. The Ki values for quetiapine and norquetiapine at the dopamine D1 are 428/99.8 nM, at D2 626/489nM, at serotonin 5HT1A 1040/191 nM at 5HT2A 38/2.9 nM, at histamine H1 4.4/1.1 nM, at muscarinic M1 1086/38.3 nM, and at adrenergic α1b 14.6/46.4 nM and, at α2 receptors 617/1290 nM, respectively. Quetiapine and norquetiapine lack appreciable affinity to the benzodiazepine receptors.

    Effect on QT Interval

    In clinical trials quetiapine was not associated with a persistent increase in QT intervals. However, the QT effect was not systematically evaluated in a thorough QT study. In post marketing experience there were cases reported of QT prolongation in patients who overdosed on quetiapine [see OVERDOSAGE (10.1)], in patients with concomitant illness, and in patients taking medicines known to cause electrolyte imbalance or increase QT interval.

    12.3 Pharmacokinetics

    Adults

    Following multiple dosing of quetiapine up to a total daily dose of 800 mg, administered in divided doses, the plasma concentration of quetiapine and norquetiapine, the major active metabolite of quetiapine, were proportional to the total daily dose. Accumulation is predictable upon multiple dosing. Steady-state mean Cmax and AUC of norquetiapine are about 21 to 27% and 46 to 56%, respectively of that observed for quetiapine. Elimination of quetiapine is mainly via hepatic metabolism. The mean-terminal half-life is approximately 7 hours for quetiapine and approximately 12 hours for norquetiapine within the clinical dose range. Steady-state concentrations are expected to be achieved within two days of dosing. Quetiapine fumarate extended-release tablet is unlikely to interfere with the metabolism of drugs metabolized by cytochrome P450 enzymes.

    Children and Adolescents

    At steady state, the pharmacokinetics of the parent compound, in children and adolescents (10 to 17 years of age), were similar to adults. However, when adjusted for dose and weight, AUC and Cmax of the parent compound were 41% and 39% lower, respectively, in children and adolescents than in adults. For the active metabolite, norquetiapine, AUC and Cmax were 45% and 31% higher, respectively, in children and adolescents than in adults. When adjusted for dose and weight, the pharmacokinetics of the metabolite, norquetiapine, was similar between children and adolescents and adults [see USE IN SPECIFIC POPULATIONS (8.4)].

    Absorption

    Quetiapine fumarate reaches peak plasma concentrations approximately 6 hours following administration. Quetiapine fumarate extended-release tablet dosed once daily at steady state has comparable bioavailability to an equivalent total daily dose of quetiapine fumarate tablet administered in divided doses, twice daily. A high-fat meal (approximately 800 to 1000 calories) was found to produce statistically significant increases in the quetiapine fumarate extended-release tablet Cmax and AUC of 44% to 52% and 20% to 22%, respectively, for the 50 mg and 300 mg tablets. In comparison, a light meal (approximately 300 calories) had no significant effect on the Cmax or AUC of quetiapine. It is recommended that quetiapine fumarate extended-release tablet be taken without food or with a light meal [see DOSAGE AND ADMINISTRATION (2.1)].

    Distribution

    Quetiapine is widely distributed throughout the body with an apparent volume of distribution of 10±4 L/kg. It is 83% bound to plasma proteins at therapeutic concentrations. In vitro, quetiapine did not affect the binding of warfarin or diazepam to human serum albumin. In turn, neither warfarin nor diazepam altered the binding of quetiapine.

    Metabolism and Elimination

    Following a single oral dose of 14C-quetiapine, less than 1% of the administered dose was excreted as unchanged drug, indicating that quetiapine is highly metabolized. Approximately 73% and 20% of the dose was recovered in the urine and feces, respectively. The average dose fraction of free quetiapine and its major active metabolite is <5% excreted in the urine.

    Quetiapine is extensively metabolized by the liver. The major metabolic pathways are sulfoxidation to the sulfoxide metabolite and oxidation to the parent acid metabolite; both metabolites are pharmacologically inactive. In vitro studies using human liver microsomes revealed that the cytochrome P450 3A4 isoenzyme is involved in the metabolism of quetiapine to its major, but inactive, sulfoxide metabolite and in the metabolism of its active metabolite norquetiapine.

    Age

    Oral clearance of quetiapine was reduced by 40% in elderly patients (≥65 years, n = 9) compared to young patients (n=12), and dosing adjustment may be necessary [see DOSAGE AND ADMINISTRATION (2.3)].

    Gender

    There is no gender effect on the pharmacokinetics of quetiapine.

    Race

    There is no race effect on the pharmacokinetics of quetiapine.

    Smoking

    Smoking has no effect on the oral clearance of quetiapine.

    Renal Insufficiency

    Patients with severe renal impairment (CLcr=10 to 30 mL/min/1.73m2, n=8) had a 25% lower mean oral clearance than normal subjects (CLcr>80 mL/min/1.73m2, n=8), but plasma quetiapine concentrations in the subjects with renal insufficiency were within the range of concentrations seen in normal subjects receiving the same dose. Dosage adjustment is therefore not needed in these patients [see USE IN SPECIFIC POPULATIONS (8.6)].

    Hepatic Insufficiency

    Hepatically impaired patients (n=8) had a 30% lower mean oral clearance of quetiapine than normal subjects. In 2 of the 8 hepatically impaired patients, AUC and Cmax were 3 times higher than those observed typically in healthy subjects. Since quetiapine is extensively metabolized by the liver, higher plasma levels are expected in the hepatically impaired population, and dosage adjustment may be needed [see DOSAGE AND ADMINISTRATION (2.4) and USE IN SPECIFIC POPULATIONS (8.7)].

    Drug-Drug Interaction Studies

    The in vivo assessments of effect of other drugs on the pharmacokinetics of quetiapine are summarized in Table 24 [see DOSAGE AND ADMINISTRATION (2.5 and 2.6) and DRUG INTERACTIONS (7.1)].

    In vitro enzyme inhibition data suggest that quetiapine and 9 of its metabolites would have little inhibitory effect on in vivo metabolism mediated by cytochromes CYP 1A2, 2C9, 2C19, 2D6 and 3A4. Quetiapine at doses of 750 mg/day did not affect the single dose pharmacokinetics of antipyrine, lithium or lorazepam (Table 25) [see DRUG INTERACTIONS (7.2)].

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis

    Carcinogenicity studies were conducted in C57BL mice and Wistar rats. Quetiapine was administered in the diet to mice at doses of 20, 75, 250, and 750 mg/kg and to rats by gavage at doses of 25, 75, and 250 mg/kg for two years. These doses are equivalent to 0.1, 0.5, 1.5, and 4.5 times the MRHD of 800 mg/day based on mg/m2 body surface area (mice) or 0.3, 1, and 3 times the MRHD based on mg/m2 body surface area (rats). There were statistically significant increases in thyroid gland follicular adenomas in male mice at doses 1.5 and 4.5 times the MRHD based on mg/m2 body surface area and in male rats at a dose of 3 times the MRHD on mg/m2 body surface area. Mammary gland adenocarcinomas were statistically significantly increased in female rats at all doses tested (0.3, 1, and 3 times the MRHD based on mg/m2body surface area).

    Thyroid follicular cell adenomas may have resulted from chronic stimulation of the thyroid gland by thyroid stimulating hormone (TSH) resulting from enhanced metabolism and clearance of thyroxine by rodent liver. Changes in TSH, thyroxine, and thyroxine clearance consistent with this mechanism were observed in subchronic toxicity studies in rat and mouse and in a 1-year toxicity study in rat; however, the results of these studies were not definitive. The relevance of the increases in thyroid follicular cell adenomas to human risk, through whatever mechanism, is unknown.

    Antipsychotic drugs have been shown to chronically elevate prolactin levels in rodents. Serum measurements in a 1-year toxicity study showed that quetiapine increased median serum prolactin levels a maximum of 32- and 13-fold in male and female rats, respectively. Increases in mammary neoplasms have been found in rodents after chronic administration of other antipsychotic drugs and are considered to be prolactin-mediated. The relevance of this increased incidence of prolactin-mediated mammary gland tumors in rats to human risk is unknown [see WARNINGS AND PRECAUTIONS (5.15)].

    Mutagenesis

    Quetiapine was not mutagenic or clastogenic in standard genotoxicity tests.The mutagenic potential of quetiapine was tested in the in vitro Ames bacterial gene mutation assay and in the in vitro mammalian gene mutation assay in Chinese Hamster Ovary cells. The clastogenic potential of quetiapine was tested in the in vitro chromosomal aberration assay in cultured human lymphocytes and in the in vivo bone marrow micronucleus assay in rats up to 500 mg/kg which is 6 times the maximum recommended human dose based on mg/m2 body surface area.

    Impairment of Fertility

    Quetiapine decreased mating and fertility in male Sprague-Dawley rats at oral doses of 50 and 150 mg/kg or approximately 1 and 3 times the MRHD of 800 mg/day based on mg/m2 body surface area. Drug-related effects included increases in interval to mate and in the number of matings required for successful impregnation. These effects continued to be observed at 3 times the MRHD even after a two-week period without treatment. The no-effect dose for impaired mating and fertility in male rats was 25 mg/kg, or 0.3 times the MRHD dose based on mg/m2 body surface area. Quetiapine adversely affected mating and fertility in female Sprague-Dawley rats at an oral dose approximately 1 times the MRHD of 800 mg/day based on mg/m2 body surface area. Drug-related effects included decreases in matings and in matings resulting in pregnancy, and an increase in the interval to mate. An increase in irregular estrus cycles was observed at doses of 10 and 50 mg/kg, or approximately 0.1 and 1 times the MRHD of 800 mg/day based on mg/m2body surface area. The no-effect dose in female rats was 1 mg/kg, or 0.01 times the MRHD of 800 mg/day based on mg/m2 body surface area.

    13.2 Animal Toxicology and/or Pharmacology

    Quetiapine caused a dose-related increase in pigment deposition in thyroid gland in rat toxicity studies which were 4 weeks in duration or longer and in a mouse 2-year carcinogenicity study. Doses were 10, 25, 50, 75, 150 and 250 mg/kg in rat studies which are approximately 0.1, 0.3, 0.6, 1, 2 and 3-times the MRHD of 800 mg/day based on mg/m2 body surface area, respectively. Doses in the mouse carcinogenicity study were 20, 75, 250 and 750 mg/kg which are approximately 0.1, 0.5, 1.5, and 4.5 times the MRHD of 800 mg/day based on mg/m2 body surface area. Pigment deposition was shown to be irreversible in rats. The identity of the pigment could not be determined, but was found to be co-localized with quetiapine in thyroid gland follicular epithelial cells. The functional effects and the relevance of this finding to human risk are unknown.

    In dogs receiving quetiapine for 6 or 12 months, but not for 1 month, focal triangular cataracts occurred at the junction of posterior sutures in the outer cortex of the lens at a dose of 100 mg/kg, or 4 times the MRHD of 800 mg/day based on mg/m2 body surface area. This finding may be due to inhibition of cholesterol biosynthesis by quetiapine. Quetiapine caused a dose-related reduction in plasma cholesterol levels in repeat-dose dog and monkey studies; however, there was no correlation between plasma cholesterol and the presence of cataracts in individual dogs. The appearance of delta 8 cholestanol in plasma is consistent with inhibition of a late stage in cholesterol biosynthesis in these species. There also was a 25% reduction in cholesterol content of the outer cortex of the lens observed in a special study in quetiapine treated female dogs. Drug-related cataracts have not been seen in any other species; however, in a 1-year study in monkeys, a striated appearance of the anterior lens surface was detected in 2/7 females at a dose of 225 mg/kg or 5.5 times the MRHD of 800 mg/day based on mg/m2body surface area.

  • 14 CLINICAL STUDIES

    14.1 Schizophrenia

    Short-term Trials - Adults

    The efficacy of quetiapine fumarate extended-release tablet in the treatment of schizophrenia was demonstrated in 1 short-term, 6-week, fixed-dose, placebo-controlled trial of inpatients and outpatients with schizophrenia (n=573) who met DSM IV criteria for schizophrenia. Quetiapine fumarate extended-release tablet (once daily) was administered as 300 mg on Day 1, and the dose was increased to either 400 mg or 600 mg by Day 2, or 800 mg by Day 3. The primary endpoint was the change from baseline of the Positive and Negative Syndrome Scale (PANSS) total score at the end of treatment (Day 42). Quetiapine fumarate extended-release tablet doses of 400 mg, 600 mg and 800 mg once daily were superior to placebo in the PANSS total score at Day 42 (study 1 in Table 26).

    Short-term Trials -Adolescents (ages 13 to 17)

    The efficacy of quetiapine fumarate extended-release tablet in the treatment of schizophrenia in adolescents (13 to 17 years of age) was supported by a 6-week, double-blind, placebo-controlled trial. Patients who met DSM-IV diagnostic criteria for schizophrenia were randomized into one of three treatment groups: quetiapine fumarate tablet 400 mg/day (n = 73), quetiapine fumarate tablet 800 mg/day (n = 74), or placebo (n = 75). Study medication was initiated at 50 mg/day and on day 2 increased to 100 mg/per day (divided and given two or three times per day). Subsequently, the dose was titrated to the target dose of 400 mg/day or 800 mg/day using increments of 100 mg/day, divided and given two or three times daily. The primary efficacy variable was the mean change from baseline in total Positive and Negative Syndrome Scale (PANSS). Quetiapine fumarate tablet at 400 mg/day and 800 mg/day was superior to placebo in the reduction of PANSS total score (study 2 in Table 26).

    Maintenance Trials

    In a longer-term trial (study 3), clinically stable adult outpatients (n=171) meeting DSM-IV criteria for schizophrenia who remained stable following 16 weeks of open-label treatment with flexible doses of quetiapine fumarate extended-release tablet (400 mg/day-800 mg/day) were randomized to placebo or to continue on their current quetiapine fumarate extended-release tablet (400 mg/day - 800 mg/day) for observation for possible relapse during the double-blind continuation (maintenance) phase. Stabilization during the open-label phase was defined as receiving a stable dose of quetiapine fumarate extended-release tablet and having a CGI-S≤4 and a PANSS score ≤60 from beginning to end of this open-label phase (with no increase of ≥10 points in PANSS total score). Relapse during the double-blind phase was defined in terms of a ≥30% increase in the PANSS Total score, or CGI-Improvement score of ≥6, or hospitalization due to worsening of schizophrenia, or need for any other antipsychotic medication. Patients on quetiapine fumarate extended-release tablet experienced a statistically significant longer time to relapse than did patients on placebo (Figure 1).

    14.2 Bipolar Disorder

    Bipolar I Disorder, manic or mixed episodes

    Adults

    The efficacy of quetiapine fumarate extended-release tablet in the acute treatment of manic episodes was established in one 3-week, placebo-controlled trial (Study 1 in Table 27) in patients who met DSM-IV criteria for bipolar I disorder with manic or mixed episodes with or without psychotic features (N=316). Patients were hospitalized for a minimum of 4 days at randomization. Patients randomized to quetiapine fumarate extended-release tablet received 300 mg on Day 1 and 600 mg on Day 2. Afterwards, the dose could be adjusted between 400 mg and 800 mg per day.

    The primary rating instrument used for assessing manic symptoms in these trials was the Young Mania Rating Scale (YMRS), an 11-item clinician-rated scale traditionally used to assess the degree of manic symptoms in a range from 0 (no manic features) to 60 (maximum score). Quetiapine fumarate extended-release tablet was superior to placebo in the reduction of the YMRS total score at week 3.

    The efficacy of quetiapine fumarate tablet in the treatment of acute manic episodes was also established in 3 placebo-controlled trials in patients who met DSM-IV criteria for bipolar I disorder with manic episodes. These trials included patients with or without psychotic features and excluded patients with rapid cycling and mixed episodes. Of these trials, 2 were monotherapy (12 weeks) and 1 was adjunct therapy (3 weeks) to either lithium or divalproex. Key outcomes in these trials were change from baseline in the YMRS score at 3 and 12 weeks for monotherapy and at 3 weeks for adjunct therapy. Adjunct therapy is defined as the simultaneous initiation or subsequent administration of quetiapine fumarate tablet with lithium or divalproex.

    The results of the trials follow:

    Monotherapy

    In two 12-week trials (n=300, n=299) comparing quetiapine fumarate tablet to placebo, quetiapine fumarate tablet was superior to placebo in the reduction of the YMRS total score at weeks 3 and 12. The majority of patients in these trials taking quetiapine tablet were dosed in a range between 400 mg/day and 800 mg/ day (Studies 2 and 3 in Table 27).

    Adjunct Therapy

    In a 3-week placebo-controlled trial, 170 patients with bipolar mania (YMRS ≥ 20) were randomized to receive quetiapine fumarate tablet or placebo as adjunct treatment to lithium or divalproex. Patients may or may not have received an adequate treatment course of lithium or divalproex prior to randomization. Quetiapine fumarate tablet was superior to placebo when added to lithium or divalproex alone in the reduction of YMRS total score. The majority of patients in this trial taking quetiapine tablet were dosed in a range between 400 mg/day and 800 mg/day (study 4 in Table 27).

    Children and Adolescents (ages 10 to 17)

    The efficacy of quetiapine fumarate extended-release tablet in the acute treatment of manic episodes associated with bipolar I disorder in children and adolescents (10 to 17 years of age) was extrapolated from a 3-week, double-blind, placebo-controlled, multicenter trial. Patients who met DSM-IV diagnostic criteria for a manic episode were randomized into one of three treatment groups: quetiapine fumarate tablet 400 mg/day (n = 95), quetiapine fumarate tablet 600 mg/day (n = 98), or placebo (n = 91). Study medication was initiated at 50 mg/day and on day 2 increased to 100 mg/day (divided doses given two or three times daily). Subsequently, the dose was titrated to a target dose of 400 mg/day or 600 mg/day using increments of 100 mg/day, given in divided doses two or three times daily. The primary efficacy variable was the mean change from baseline in total YMRS score. Quetiapine fumarate tablet 400 mg/day and 600 mg/day were superior to placebo in the reduction of YMRS total score (study 5 in Table 27).

    Bipolar Disorder, Depressive Episodes

    Adults:

    The efficacy of quetiapine fumarate extended-release tablet for the acute treatment of depressive episodes associated with bipolar disorder in patients who met DSM-IV criteria for bipolar disorder was established in one 8-week, randomized, double-blind, placebo-controlled study (N=280 outpatients). This study included patients with bipolar I and II disorder, and those with and without a rapid cycling course. Patients randomized to quetiapine fumarate extended-release tablet were administered 50 mg on Day 1, 100 mg on Day 2, 200 mg on Day 3, and 300 mg on Day 4 and after.

    The primary rating instrument used to assess depressive symptoms was the Montgomery-Asberg Depression Rating Scale (MADRS), a 10-item clinician-rated scale with scores ranging from 0 (no depressive features) to 60 (maximum score). The primary endpoint was the change from baseline in MADRS score at week 8. Quetiapine fumarate extended-release tablet was superior to placebo in reduction of MADRS score at week 8 (study 6 in Table 28).

    The efficacy of quetiapine fumarate tablet for the treatment of depressive episodes associated with bipolar disorder was established in 2 identical 8-week, randomized, double-blind, placebo-controlled studies (N=1045). These studies included patients with either bipolar I or II disorder and those with or without a rapid cycling course. Patients randomized to quetiapine tablet were administered fixed doses of either 300 mg or 600 mg once daily.

    The primary rating instrument used to assess depressive symptoms in these studies was the MADRS. The primary endpoint in both studies was the change from baseline in MADRS score at week 8. In both studies, quetiapine fumarate tablet was superior to placebo in reduction of MADRS score at week 8 (Studies 7 and 8 in Table 28). In these studies, no additional benefit was seen with the 600 mg dose. For the 300 mg dose group, statistically significant improvements over placebo were seen in overall quality of life and satisfaction related to various areas of functioning, as measured using the Q-LES-Q(SF).

    Maintenance Treatment as an Adjunct to Lithium or Divalproex

    The efficacy of quetiapine fumarate tablet in the maintenance treatment of bipolar I disorder was established in 2 placebo-controlled trials in patients (n=1326) who met DSM-IV criteria for bipolar I disorder (studies 9 and 10). The trials included patients whose most recent episode was manic, depressed, or mixed, with or without psychotic features. In the open-label phase, patients were required to be stable on quetiapine tablet plus lithium or divalproex for at least 12 weeks in order to be randomized. On average, patients were stabilized for 15 weeks. In the randomization phase, patients continued treatment with lithium or divalproex and were randomized to receive either quetiapine fumarate tablet (administered twice-daily totaling 400 mg/day to 800 mg/day) or placebo. Approximately 50% of the patients had discontinued from the quetiapine fumarate tablet group by day 280 and 50% of the placebo group had discontinued by day 117 of double-blind treatment. The primary endpoint in these studies was time to recurrence of a mood event (manic, mixed or depressed episode). A mood event was defined as medication initiation or hospitalization for a mood episode; YMRS score ≥ 20 or MADRS score ≥ 20 at 2 consecutive assessments; or study discontinuation due to a mood event.

    In both studies, quetiapine fumarate tablet was superior to placebo in increasing the time to recurrence of any mood event (Figure 2 and Figure 3). The treatment effect was present for increasing time to recurrence of both manic and depressed episodes. The effect of quetiapine fumarate tablet was independent of any specific subgroup (assigned mood stabilizer, sex, age, race, most recent bipolar episode, or rapid cycling course).

    14.3 Major Depressive Disorder, Adjunctive Therapy to Antidepressants

    The efficacy of quetiapine fumarate extended-release tablet as adjunctive therapy to antidepressants in the treatment of MDD was demonstrated in two 6-week placebo-controlled, fixed-dose trials (n=936). Quetiapine fumarate extended-release tablet 150 mg/day or 300 mg/day was given as adjunctive therapy to existing antidepressant therapy in patients who had previously shown an inadequate response to at least one antidepressant. Quetiapine fumarate extended-release tablet was administered as 50 mg/day on Days 1 and 2, and increased to 150 mg/day on Day 3 for both dose groups. On Day 5, the dose was increased to 300 mg/day in the 300 mg/day fixed-dose group. Inadequate response was defined as having continued depressive symptoms for the current episode [Hamilton Depression Rating Scale (HAM-D) total score of ≥ 20] despite using an antidepressant for 6 weeks at or above the minimally effective labelled dose. The mean HAM-D total score at entry was 24, and 17% of patients scored 28 or greater. Patients were on various antidepressants prior to study entry including SSRI's (paroxetine, fluoxetine, sertraline, escitalopram, or citalopram), SNRI's, (duloxetine and venlafaxine,) TCA (amitriptyline), and other (bupropion).

    The primary endpoint in these trials was change from baseline to week 6 in the Montgomery-Asberg Depression Rating Scale (MADRS.), quetiapine fumarate extended-release tablet 300 mg once daily as adjunctive treatment to other antidepressant therapy was superior to antidepressant alone in reduction of MADRS total score in both trials. Quetiapine fumarate extended-release tablet 150 mg once daily as adjunctive treatment was superior to antidepressant therapy alone in reduction of MADRS total score in one trial. (studies 1 and 2 in Table 29).

    Patients, their families, and their caregivers should be encouraged to be alert to the emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, mania, other unusual changes in behavior, worsening of depression, and suicidal ideation, especially early during antidepressant treatment and when the dose is adjusted up or down. Families and caregivers of patients should be advised to look for the emergence of such symptoms on a day-to-day basis, since changes may be abrupt. Such symptoms should be reported to the patient's prescriber or health professional, especially if they are severe, abrupt in onset, or were not part of the patient's presenting symptoms. Symptoms such as these may be associated with an increased risk for suicidal thinking and behavior and indicate a need for very close monitoring and possibly changes in the medication [see WARNINGS AND PRECAUTIONS (5.2)].

    Neuroleptic Malignant Syndrome (NMS)

    Patients should be advised to report to their physician any signs or symptoms that may be related to NMS. These may include muscle stiffness and high fever [see WARNINGS AND PRECAUTIONS (5.4)].

    Hyperglycemia and Diabetes Mellitus

    Patients should be aware of the symptoms of hyperglycemia (high blood sugar) and diabetes mellitus. Patients who are diagnosed with diabetes, those with risk factors for diabetes, or those that develop these symptoms during treatment should have their blood glucose monitored at the beginning of and periodically during treatment [see WARNINGS AND PRECAUTIONS (5.5)].

    Hyperlipidemia

    Patients should be advised that elevations in total cholesterol, LDL-cholesterol and triglycerides and decreases in HDL-cholesterol may occur. Patients should have their lipid profile monitored at the beginning of and periodically during treatment [see WARNINGS AND PRECAUTIONS (5.5)].

    Weight Gain

    Patients should be advised that they may experience weight gain. Patients should have their weight monitored regularly [see WARNINGS AND PRECAUTIONS (5.5)].

    Orthostatic Hypotension

    Patients should be advised of the risk of orthostatic hypotension (symptoms include feeling dizzy or lightheaded upon standing, which may lead to falls) especially during the period of initial dose titration, and also at times of re-initiating treatment or increases in dose [see WARNINGS AND PRECAUTIONS (5.7)].

    Increased Blood Pressure in Children and Adolescents 

    Children and adolescent patients should have their blood pressure measured at the beginning of, and periodically during, treatment [see WARNINGS AND PRECAUTIONS (5.9)].

    Leukopenia/Neutropenia

    Patients with a pre-existing low WBC or a history of drug induced leukopenia/neutropenia should be advised that they should have their CBC monitored while taking quetiapine fumarate extended-release tablet. Patients should be advised to talk to their doctor as soon as possible if they have a fever, flu-like symptoms, sore throat, or any other infection as this could be a result of a very low WBC, which may require quetiapine fumarate extended-release tablet to be stopped and/or treatment to be given [see WARNINGS AND PRECAUTIONS (5.10)].

    Interference with Cognitive and Motor Performance 

    Patients should be advised of the risk of somnolence or sedation (which may lead to falls), especially during the period of initial dose titration. Patients should be cautioned about performing any activity requiring mental alertness, such as operating a motor vehicle (including automobiles) or operating machinery, until they are reasonably certain quetiapine therapy does not affect them adversely [see WARNINGS AND PRECAUTIONS (5.16)].

    Heat Exposure and Dehydration

    Patients should be advised regarding appropriate care in avoiding overheating and dehydration [see WARNINGS AND PRECAUTIONS (5.17)].

    Concomitant Medication

    As with other medications, patients should be advised to notify their physicians if they are taking, or plan to take, any prescription or over-the-counter drugs [see DRUG INTERACTIONS (7.1)].

    Pregnancy

    Advise pregnant women to notify their healthcare provider if they become pregnant or intend to become pregnant during treatment with quetiapine fumarate extended-release tablet. Advise patients that quetiapine fumarate extended-release tablet may cause extrapyramidal and/or withdrawal symptoms (agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder) in a neonate. Advise patients that there is a pregnancy registry that monitors pregnancy outcomes in women exposed to quetiapine fumarate extended-release tablet during pregnancy [see USE IN SPECIFIC POPULATIONS (8.1)].

    Infertility

    Advise females of reproductive potential that quetiapine fumarate extended-release tablet may impair fertility due to an increase in serum prolactin levels. The effects on fertility are reversible [see USE IN SPECIFIC POPULATIONS (8.3)].

    Need for Comprehensive Treatment Program 

    Quetiapine fumarate extended-release tablet is indicated as an integral part of a total treatment program for adolescents with schizophrenia and pediatric bipolar disorder that may include other measures (psychological, educational, and social). Effectiveness and safety of quetiapine fumarate extended-release tablet have not been established in pediatric patients less than 13 years of age for schizophrenia or less than 10 years of age for bipolar mania. Appropriate educational placement is essential and psychosocial intervention is often helpful. The decision to prescribe atypical antipsychotic medication will depend upon the physician's assessment of the chronicity and severity of the patient's symptoms [see INDICATIONS AND USAGE (1.4)].

  • MEDICATION GUIDE

    Quetiapine Fumarate Extended-Release Tablet

    (kweh-TYE-uh-peen)

    Read this Medication Guide before you start taking quetiapine fumarate extended-release tablet and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking to your healthcare provider about your medical condition or treatment.

    What is the most important information I should know about quetiapine fumarate extended-release tablet?

    Quetiapine fumarate extended-release tablet may cause serious side effects, including:

        1    Risk of death in the elderly with dementia: Medicines like quetiapine fumarate extended-release tablet can increase the risk of death in elderly people who have memory loss (dementia). Quetiapine fumarate extended-release tablet is not for treating psychosis in the elderly with dementia.

        2    Risk of suicidal thoughts or actions (antidepressant medicines, depression and other serious mental illnesses, and suicidal thoughts or actions).

    Talk to your or your family member's, healthcare provider about:

                    all risks and benefits of treatment with antidepressant medicines

                    all treatment choices for depression or other serious mental illness

            Antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, and young adults within the first few months of treatment.

            Depression and other serious mental illnesses are the most important causes of suicidal thoughts and actions. Some people may have a particularly high risk of having suicidal thoughts or actions. These include people who have (or have a family history of) depression, bipolar illness (also called manic-depressive illness), or suicidal thoughts or actions.

            How can I watch for and try to prevent suicidal thoughts and actions in myself or a family member?

                    Pay close attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. This is very important when an antidepressant medicine is started or when the dose is changed.

                    Call the healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings.

                    Keep all follow-up visits with the healthcare provider as scheduled. Call the healthcare provider between visits as needed, especially if you have concerns about symptoms.

    Call a healthcare provider right away if you or your family member has any of the following symptoms, especially if they are new, worse, or worry you:

            thoughts about suicide or dying

            attempts to commit suicide

            new or worse depression

            new or worse anxiety

            feeling very agitated or restless

            panic attacks

            trouble sleeping (insomnia)

            new or worse irritability

            acting aggressive, being angry, or violent

            acting on dangerous impulses

            an extreme increase in activity and talking (mania)

            other unusual changes in behavior or mood

    What else do I need to know about antidepressant medicines?

            Never stop an antidepressant medicine without first talking to your healthcare provider. Stopping an antidepressant medicine suddenly can cause other symptoms.

            Antidepressants are medicines used to treat depression and other illnesses. It is important to discuss all the risks of treating depression and also the risks of not treating it. Patients and their families or other caregivers should discuss all treatment choices with the healthcare provider, not just the use of antidepressants.

            Antidepressant medicines have other side effects. Talk to the healthcare provider about the side effects of the medicine prescribed for you or your family member.

            Antidepressant medicines can interact with other medicines. Know all of the medicines that you or your family member take. Keep a list of all medicines to show the healthcare provider. Do not start new medicines without first checking with your healthcare provider.

            Not all antidepressant medicines prescribed for children are FDA approved for use in children. Talk to your child's healthcare provider for more information.

    What is quetiapine fumarate extended-release tablet?

                    long-term treatment of bipolar I disorder with lithium or divalproex

            manic episodes associated with bipolar I disorder in children ages 10 to 17 years old
