2.2 Depressive Episodes Associated with Bipolar I Disorder

Adults

The  recommended  starting  dose  of  lurasidone hydrochloride tablets  is  20  mg  given  once  daily  as monotherapy or as adjunctive therapy with lithium or valproate. Initial dose titration is not required. Lurasidone hydrochloride tablets has been shown to be effective in a dose range of 20 mg per day to 120 mg per day as monotherapy or as adjunctive therapy with lithium or valproate [see Clinical Studies ( 14.2)] .  The  maximum  recommended  dose,  as  monotherapy  or  as  adjunctive  therapy  with lithium or valproate, is 120 mg per day. In the monotherapy study, the higher dose range (80 mg to 120 mg per day) did not provide additional efficacy, on average, compared to the lower dose range (20 to 60 mg per day) [see Clinical Studies ( 14.2)].

Pediatric Patients (10 – 17 years)

The recommended starting dose of lurasidone hydrochloride tablets is 20 mg given once daily as monotherapy. Initial dose titration is not required. The dose may be increased after one week based on clinical response. Lurasidone hydrochloride tablets has been shown to be effective in a dose range of 20 mg per day to 80 mg per day as monotherapy. At the end of the clinical study, most of the patients (67%) received 20 mg or 40 mg once daily [see Clinical Studies ( 14.2)] . The maximum recommended dose is 80 mg per day.

The efficacy of lurasidone hydrochloride tablets in the treatment of mania associated with bipolar disorder has not been established.

2.3 Administration Information

Lurasidone hydrochloride tablets should be taken with food (at least 350 calories). Administration with food substantially increases the absorption of lurasidone hydrochloride tablets. Administration with food increases the AUC approximately 2-fold and increases the Cmax approximately 3-fold. In the clinical studies, lurasidone hydrochloride tablets were administered with food [see Clinical Pharmacology (12.3)] .

The effectiveness of lurasidone hydrochloride tablets for longer-term use, that is, for more than 6 weeks, has not been established in controlled studies. Therefore, the physician who elects to use lurasidone hydrochloride tablets for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient [see Dosage and Administration (2.2)] .

2.4 Dose Modifications for Renal Impairment

Dose adjustment is recommended in moderate (creatinine clearance: 30 to <50 mL/min) and severe renal impairment (creatinine clearance <30 mL/min) patients. The recommended starting dose is 20 mg per day. The dose in these patients should not exceed 80 mg per day [see Use in Specific Populations (8.6)].

2.5 Dose Modifications for Hepatic Impairment

Dose adjustment is recommended in moderate (Child-Pugh Score = 7 to 9) and severe hepatic impairment (Child-Pugh Score = 10 to 15) patients. The recommended starting dose is 20 mg per day. The dose in moderate hepatic impairment patients should not exceed 80 mg per day and the dose in severe hepatic impairment patients should not exceed 40 per mg/day [see Use in Specific Populations (8.7)].

2.6 Dose Modifications Due to Drug Interactions of CYP3A4 Inhibitors and CYP3A4 Inducers

Concomitant Use with CYP3A4 Inhibitors 

Lurasidone hydrochloride tablets should not be used concomitantly with a strong CYP3A4 inhibitor (e.g., ketoconazole, clarithromycin, ritonavir, voriconazole, mibefradil, etc.) [see Contraindications (4)] .

If lurasidone hydrochloride tablets are being prescribed and a moderate CYP3A4 inhibitor (e.g. diltiazem, atazanavir, erythromycin, fluconazole, verapamil etc.) is added to the therapy, the lurasidone hydrochloride tablets dose should be reduced to half of the original dose level. Similarly, if a moderate CYP3A4 inhibitor is being prescribed and lurasidone hydrochloride tablets are added to the therapy, the recommended starting dose of lurasidone hydrochloride tablets is 20 mg per day, and the maximum recommended dose of lurasidone hydrochloride tablets is 80 mg per day [see Contraindications (4), Drug Interactions (7.1)] .

Grapefruit and grapefruit juice should be avoided in patients taking lurasidone hydrochloride tablets, since these may inhibit CYP3A4 and alter lurasidone hydrochloride tablets concentrations [ see Drug Interactions (7.1)].

Concomitant Use with CYP3A4 Inducers 

Lurasidone hydrochloride tablets should not be used concomitantly with a strong CYP3A4 inducer (e.g., rifampin, avasimibe, St. John’s wort, phenytoin, carbamazepine, etc.) [see Contraindications (4); Drug Interactions (7.1)] . If lurasidone hydrochloride tablets are used concomitantly with a moderate CYP3A4 inducer, it may be necessary to increase the lurasidone hydrochloride tablets dose after chronic treatment (7 days or more) with the CYP3A4 inducer.

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. Analyses 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. Lurasidone hydrochloride tablets are not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions (5.3)] .

5.2 Suicidal Thoughts and Behaviors in Pediatric and Young Adult Patients

In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant  classes)  that  included  approximately  77,000  adult  patients,  and  over  4,400 pediatric patients, the incidence of suicidal thoughts and behaviors in pediatric and young adult patients was greater in antidepressant-treated patients than in placebo-treated patients. The drug- placebo differences in the number of cases of suicidal thoughts and behaviors per 1000 patients treated are provided in Table 2.

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

Table 2: Risk Differences of the Number of Cases of Suicidal Thoughts or Behaviors in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric and Adult Patients

It is unknown whether the risk of suicidal thoughts and behaviors in pediatric and young adult patients extends to longer-term use, i.e., beyond four months. However, there is substantial evidence from placebo-controlled maintenance studies in adults with MDD that antidepressants delay the recurrence of depression.

Monitor all antidepressant-treated patients for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy and at times of dosage changes. Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider. Consider changing the therapeutic regimen, including possibly discontinuing lurasidone hydrochloride tablets, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.

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. Lurasidone hydrochloride tablets are not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions (5.1)].

5.4 Neuroleptic Malignant Syndrome

A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with administration of antipsychotic drugs, including lurasidone hydrochloride tablets. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability. Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure.

If NMS is suspected, immediately discontinue lurasidone hydrochloride tablets and provide intensive symptomatic treatment and monitoring.

5.5 Tardive Dyskinesia

Tardive dyskinesia is a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements that can develop in patients treated with antipsychotic drugs. 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.

The syndrome 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, lurasidone hydrochloride tablets 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 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 lurasidone hydrochloride tablets, drug discontinuation should be considered. However, some patients may require treatment with lurasidone hydrochloride tablets despite the presence of the syndrome.

5.6 Metabolic Changes

Atypical antipsychotic drugs have been associated with metabolic changes that may increase cardiovascular/cerebrovascular risk. These metabolic changes include hyperglycemia, 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.

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. 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 events is not completely understood. However, epidemiological studies suggest an increased risk of hyperglycemia-related adverse events in patients treated with the atypical antipsychotics. 

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.

Pediatric Patients (10 to 17 years)

In studies of pediatric patients 10 to 17 years and adults with bipolar depression, changes in fasting glucose were similar. In the 6-week, placebo-controlled study of pediatric patients with bipolar depression, mean change in fasting glucose was +1.6 mg/dL for   lurasidone hydrochloride tablets 20 to 80 mg/day (n=145) and -0.5 mg/dL for placebo (n=145).

Pediatric Patients (6 to 17 years)

In a 104-week, open-label study in pediatric patients with bipolar depression, autistic disorder, or another indication, 7 % of patients with a normal baseline fasting glucose experienced a shift to high at endpoint while taking lurasidone.

Of patients with normal baseline fasting triglycerides, 12% experienced shifts to high.

Weight Gain

Weight gain has been observed with atypical antipsychotic use. Clinical monitoring of weight is recommended.

Bipolar Depression

Adults

Monotherapy

Data from the adult short-term, flexible-dosed, placebo-controlled monotherapy bipolar depression study are presented in Table 11. The mean change in weight gain was +0.29 kg for lurasidone-treated patients compared to -0.04 kg for placebo-treated patients. The proportion of patients with a ≥7% increase in body weight (at Endpoint) was 2.4% for lurasidone-treated patients and 0.7% for placebo-treated patients.

Patients were randomized to flexibly dosed lurasidone hydrochloride tablets 20 to 120 mg/day or placebo as adjunctive therapy with lithium or valproate.

In the uncontrolled, open-label, longer-term bipolar depression study, patients who were treated with lurasidone hydrochloride tablets, as adjunctive therapy with either lithium or valproate in the short-term and continued in the longer-term study, had a mean change in weight of +1.28 kg at week 24 (n=86).

Pediatric Patients (10 to 17 years)

Data from the 6-week, placebo-controlled bipolar depression study in patients 10 to 17 years are presented in Table 13. The mean change in weight gain was +0.7 kg for lurasidone hydrochloride tablets -treated patients compared to +0.5 kg for placebo-treated patients. The proportion of patients with a ≥7% increase in body weight (at Endpoint) was 4.0% for lurasidone hydrochloride tablets -treated patients and 5.3% for placebo-treated patients.

Table 13: Mean Change in Weight (kg) from Baseline in the Bipolar Depression Study in Pediatric Patients (10 to 17 years)

Pediatric Patients (6 to 17 years)

In a long-term, open-label study that enrolled pediatric patients with bipolar depression, autistic disorder or another indication, from three short-term, placebo-controlled trials, 54% (378/701) received lurasidone for 104 weeks. The mean increase in weight from open-label baseline to Week 104 was 5.85 kg. To adjust for normal growth, z-scores were derived (measured in standard deviations [SD]), which normalize for the natural growth of children and adolescents by comparisons to age- and sex-matched population standards. A z-score change <0.5 SD is considered not clinically significant. In this trial, the mean change in z-score from open-label baseline to Week 104 was -0.06 SD for body weight and -0.13 SD for body mass index (BMI), indicating minimal deviation from the normal curve for weight gain.

5.7 Hyperprolactinemia

As with other drugs that antagonize dopamine D 2receptors, lurasidone hydrochloride tablets elevates prolactin levels. Hyperprolactinemia   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 with prolactin-elevating compounds. Long-standing hyperprolactinemia, when associated with hypogonadism, may lead to decreased bone density in both female and male patients [see Adverse Reactions ( 6)] .

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, an increase in mammary gland neoplasia was observed in a carcinogenicity study conducted with lurasidone in rats and mice  [see Nonclinical Toxicology ( 13)].  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.

Bipolar Depression

Adults

Monotherapy

The� median  change  from  baseline  to  endpoint  in  prolactin  levels,  in  the  adult  short-term, flexible-dosed, placebo-controlled monotherapy bipolar depression study, was +1.7 ng/mL and +3.5 ng/mL with lurasidone hydrochloride tablets 20 to 60 mg/day and 80 to 120 mg/day, respectively compared to + 0.3 ng/mL with placebo-treated patients. The median change from baseline to endpoint for males was +1.5 ng/mL and for females was +3.1 ng/mL. Median changes for prolactin by dose range are shown in Table 16.

Table 16: Median Change in Prolactin (ng/mL) from Baseline in the Adult Monotherapy Bipolar Depression Study

Patients were randomized to flexibly dosed lurasidone hydrochloride tablets 20 to 60 mg/day, lurasidone hydrochloride tablets 80 to 120 mg/day, or placebo

The proportion of patients with prolactin elevations ≥5x upper limit of normal (ULN) was 0.4% for lurasidone hydrochloride tablets -treated patients and 0.0% for placebo-treated patients. The proportion of female patients with prolactin elevations ≥5x ULN was 0.6% for lurasidone hydrochloride tablets -treated patients and 0% for placebo-treated female patients. The proportion of male patients with prolactin elevations ≥5x ULN was 0% and 0% for placebo-treated male patients.

In the uncontrolled, open-label, longer-term bipolar depression study, patients who were treated with lurasidone hydrochloride tablets as monotherapy in the short-term and continued in the longer-term study, had a median change in prolactin of -1.15 ng/mL at week 24 (n=130).

Adjunctive Therapy with Lithium or Valproate

The  median  change  from  baseline  to  endpoint  in  prolactin  levels,  in  the  adult  short-term, flexible-dosed, placebo-controlled adjunctive therapy bipolar depression studies was +2.8 ng/mL with lurasidone hydrochloride tablets 20 to 120 mg/day compared to 0.0 ng/mL with placebo-treated patients. The median change from baseline to endpoint for males was +2.4 ng/mL and for females was +3.2 ng/mL. Median changes for prolactin across the dose range are shown in Table 17.

Table 17:        Median Change in Prolactin (ng/mL) from Baseline in the Adult Adjunctive

Therapy Bipolar Depression Studies

Patients were randomized to flexibly dosed lurasidone hydrochloride tablets 20 to 120 mg/day or placebo as adjunctive therapy with lithium or valproate.

The proportion of patients with prolactin elevations ≥5x upper limit of normal (ULN) was 0.0% for lurasidone hydrochloride tablets -treated patients and 0.0% for placebo-treated patients. The proportion of female patients with prolactin elevations ≥5x ULN was 0% for lurasidone hydrochloride tablets -treated patients and 0% for placebo-treated female patients. The proportion of male patients with prolactin elevations ≥5x ULN was 0% and 0% for placebo-treated male patients.

In the uncontrolled, open-label, longer-term bipolar depression study, patients who were treated with lurasidone hydrochloride tablets, as adjunctive therapy with either lithium or valproate, in the short-term and continued in the longer-term study, had a median change in prolactin of -2.9 ng/mL at week 24 (n=88).

Pediatric Patients (10 to 17 years)

In the 6-week, placebo-controlled bipolar depression study with pediatric patients 10 to 17 years, the median change from baseline to endpoint in prolactin levels for lurasidone hydrochloride tablets-treated patients was +1.10 ng/mL and was +0.50 ng/mL for placebo-treated patients. For lurasidone hydrochloride tablets-treated patients, the median change from baseline to endpoint for males was +0.85 ng/mL and for females was +2.50 ng/mL. Median changes for prolactin are shown in Table 18.

Table 18: Median Change in Prolactin (ng/mL) from Baseline in the Bipolar Depression Study in Pediatric Patients (10 to 17 years)

The proportion of patients with prolactin elevations ≥5x ULN was 0% for lurasidone hydrochloride-treated patients and 0.6% for placebo-treated patients. The proportion of female patients with prolactin elevations ≥5x ULN was 0% for lurasidone hydrochloride-treated patients and 1.3% for placebo-treated female patients. No male patients in the placebo or lurasidone hydrochloride treatment groups had prolactin elevations ≥5x ULN.

Pediatric Patients (6 to 17 years)

In a 104-week, open-label study of pediatric patients with bipolar depression, autistic disorder, or another indication the median changes from baseline to endpoint in serum prolactin levels were -0.20 ng/mL (all patients), -0.30 ng/mL (females), and -0.05 ng/mL (males). The proportions of patients with a markedly high prolactin level (≥5 times the upper limit of normal) at any time during open-label treatment were 2% (all patients), 3% (females), and 1% (males).

Adverse events among females in this trial that are potentially prolactin-related include galactorrhea (0.6%). Among male patients in this study, decreased libido was reported in one patient (0.2%) and there were no reports of impotence, gynecomastia, or galactorrhea.

5.8 Leukopenia, Neutropenia and Agranulocytosis

Leukopenia/neutropenia has been reported during treatment with antipsychotic agents. Agranulocytosis (including fatal cases) has been reported with other agents in the class.

Possible risk factors for leukopenia/neutropenia include pre-existing low white blood 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 lurasidone hydrochloride tablets should be discontinued at the first sign of decline in WBC, in the 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 lurasidone hydrochloride tablets and have their WBC followed until recovery.

5.9 Orthostatic Hypotension and Syncope

Lurasidone hydrochloride tablets may cause orthostatic hypotension and syncope, perhaps due to its α1-adrenergic receptor antagonism. Associated adverse reactions can include dizziness, lightheadedness, tachycardia, and bradycardia. Generally, these risks are greatest at the beginning of treatment and during dose escalation. Patients at increased risk of these adverse reactions or at increased risk of developing complications from hypotension include those with dehydration, hypovolemia, treatment with antihypertensive medication, history of cardiovascular disease (e.g., heart failure, myocardial infarction, ischemia, or conduction abnormalities), history of cerebrovascular disease, as well as patients who are antipsychotic-naïve. In such patients, consider using a lower starting dose and slower titration, and monitor orthostatic vital signs.

Orthostatic hypotension, as assessed by vital sign measurement, was defined by the following vital sign changes: ≥ 20 mm Hg decrease in systolic blood pressure and ≥10 bpm increase in pulse from sitting to standing or supine to standing position.

Bipolar Depression

Adults

Monotherapy

In the adult short-term, flexible-dose, placebo-controlled monotherapy bipolar depression study, there were no reported adverse events of orthostatic hypotension and syncope. Orthostatic hypotension, as assessed by vital signs, occurred with a frequency of 0.6% with lurasidone hydrochloride tablets 20 to 60 mg and 0.6% with lurasidone hydrochloride tablets 80 to 120 mg compared to 0% with placebo.

Adjunctive Therapy with Lithium or Valproate

In the adult short-term, flexible-dose, placebo-controlled adjunctive therapy bipolar depression therapy studies, there were no reported adverse events of orthostatic hypotension and syncope. Orthostatic hypotension, as assessed by vital signs, occurred with a frequency of 1.1% with lurasidone hydrochloride tablets 20 to 120 mg compared to 0.9% with placebo.

Pediatric Patients (10 to 17 years) 
In the 6-week, placebo-controlled bipolar depression study in pediatric patients 10 to 17 years, there were no reported adverse events of orthostatic hypotension or syncope. Orthostatic hypotension, as assessed by vital signs, occurred with a frequency of 1.1% with lurasidone hydrochloride tablets 20 to 80 mg/day, compared to 0.6% with placebo.

5.10 Falls

Lurasidone hydrochloride tablets 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.

5.11 Seizures

As with other antipsychotic drugs, lurasidone hydrochloride tablets should be used cautiously in patients with a history of seizures or with conditions that lower the seizure threshold, e.g., Alzheimer’s dementia. Conditions that lower the seizure threshold may be more prevalent in patients 65 years or older.

Bipolar Depression

Monotherapy

In the adult and pediatric 6-week, flexible-dose, placebo-controlled monotherapy bipolar depression studies, no patients experienced seizures/convulsions.
Adjunctive Therapy with Lithium or Valproate

In the adult short-term, flexible-dose, placebo-controlled adjunctive therapy bipolar depression studies, no patient experienced seizures/convulsions.

5.12 Potential for Cognitive and Motor Impairment

Lurasidone hydrochloride tablets, like other antipsychotics, has the potential to impair judgment, thinking or motor skills. Caution patients about operating hazardous machinery, including motor vehicles, until they are reasonably certain that therapy with lurasidone hydrochloride tablets does not affect them adversely.
In clinical studies with lurasidone hydrochloride tablets, somnolence included:  hypersomnia, hypersomnolence, sedation and somnolence.

Bipolar Depression

Adults

Monotherapy

In the adult short-term, flexible-dosed, placebo-controlled monotherapy bipolar depression study, somnolence was reported by 7.3% (12/164) and 13.8% (23/167) with lurasidone hydrochloride tablets 20 to 60 mg and 80 to120 mg, respectively compared to 6.5% (11/168) of placebo patients.

Adjunctive Therapy with Lithium or Valproate

In the adult short-term, flexible-dosed, placebo-controlled adjunctive therapy bipolar depression studies, somnolence was reported by 11.4% (41/360) of patients treated with lurasidone hydrochloride tablets 20-120 mg compared to 5.1% (17/334) of placebo patients.

Pediatric Patients (10 to 17 years)
In the 6-week, placebo-controlled bipolar depression study in pediatric patients 10 to 17 years, somnolence was reported by 11.4% (20/175) of patients treated with lurasidone hydrochloride tablets 20 to 80 mg/day compared to 5.8% (10/172) of placebo treated patients.

5.13 Body Temperature Dysregulation

Disruption of the body’s ability to reduce core body temperature has been attributed to antipsychotic agents.  Appropriate care is advised when prescribing lurasidone hydrochloride tablets for patients who will be experiencing conditions that 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 .

5.14 Activation of Mania/Hypomania

Antidepressant treatment can increase the risk of developing a manic or hypomanic episode, particularly in patients with bipolar disorder.  Monitor patients for the emergence of such episodes.

In the adult bipolar depression monotherapy and adjunctive therapy (with lithium or valproate) studies, less than 1% of subjects in the lurasidone hydrochloride tablets and placebo groups developed manic or hypomanic episodes.

5.15 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. Lurasidone hydrochloride tablets and other antipsychotic drugs should be used cautiously in patients at risk for aspiration pneumonia.

5.16 Neurological Adverse Reactions in Patients with Parkinson's Disease or Dementia with Lewy Bodies

Patients with Parkinson’s Disease or Dementia with Lewy Bodies are reported to have an increased sensitivity to antipsychotic medication. Manifestations of this increased sensitivity include   confusion,   obtundation, postural instability with frequent falls, extrapyramidal symptoms, and clinical features consistent with the neuroleptic malignant syndrome.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in 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 an integrated clinical study database for lurasidone hydrochloride tablets consisting of 3799 adult patients exposed to one or more doses of lurasidone hydrochloride tablets for the treatment of bipolar depression and another indication in placebo-controlled studies. This experience corresponds with a total experience of 1250.9 patient-years. A total of 1106 lurasidone hydrochloride tablets -treated patients had at least 24 weeks and 371 lurasidone hydrochloride tablets -treated patients had at least 52 weeks of exposure.

Adverse events during exposure to study treatment were obtained by general inquiry and voluntarily reported adverse experiences, as well as results from physical examinations, vital signs, ECGs, weights and laboratory investigations. Adverse experiences were recorded by clinical investigators using their own terminology. In order to provide a meaningful estimate of the proportion of individuals experiencing adverse events, events were grouped in standardized categories using MedDRA terminology.

Adjunctive Therapy with Lithium or Valproate

The mean change from baseline for lurasidone-treated adult patients for the SAS, BAS and AIMS was comparable to placebo-treated patients. The percentage of patients who shifted from normal to abnormal was greater in lurasidone-treated patients and placebo for the BAS (lurasidone, 8.7%; placebo, 2.1%), the SAS (lurasidone, 2.8%; placebo, 2.1%) and the AIMS (lurasidone, 2.8%; placebo, 0.6%).

Pediatric Patients (10 to 17 years)

The mean change from baseline for lurasidone hydrochloride tablets- treated pediatric patients 10 to 17 years with bipolar depression for the SAS, BAS and AIMS was comparable to placebo-treated patients. The percentage of patients who shifted from normal to abnormal was greater in lurasidone hydrochloride tablets-treated patients and placebo for the BAS (lurasidone hydrochloride tablets, 4.6%; placebo, 2.4%), the SAS (lurasidone hydrochloride tablets, 0.6%; placebo, 0%) and was the same for the AIMS (lurasidone hydrochloride tablets, 0%; placebo, 0%).

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.

Bipolar Depression

Adults

Monotherapy

In the adult short-term, flexible-dose, placebo-controlled monotherapy bipolar depression study, dystonia occurred in 0.9% of lurasidone hydrochloride tablets -treated subjects (0.0% and 1.8% for lurasidone hydrochloride tablets 20 to 60 mg/day and lurasidone hydrochloride tablets 80 to 120 mg/day, respectively) compared to 0.0% of subjects receiving placebo.

6.2 Postmarketing Experience

The  following  adverse  reactions  have  been  identified  during  postapproval  use  of  lurasidone hydrochloride tablets. 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.

Hypersensitivity Reactions:  Urticaria, throat swelling, tongue swelling, dyspnea, and rash.

Metabolism and Nutrition Disorders: Hyponatremia

7.1 Drugs Having Clinically Important Interactions with lurasidone hydrochloride tablets

Table 34: Clinically Important Drug Interactions with lurasidone hydrochloride tablets

7.2 Drugs Having No Clinically Important Interactions with lurasidone hydrochloride tablets

Based on pharmacokinetic studies, no dosage adjustment of lurasidone hydrochloride tablets are required when administered concomitantly with lithium, valproate, or substrates of P-gp or CYP3A4 [see Clinical Pharmacology (12.3)] .

8.1 Pregnancy

Pregnancy Exposure Registry

There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to lurasidone hydrochloride tablets during pregnancy. For more information, contact the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit http://womensmentalhealth.org/clinical-and­ research-programs/pregnancyregistry/.

Risk Summary

Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery [see Clinical Considerations]. There are no studies of lurasidone hydrochloride tablets use in pregnant women. The limited available data are not sufficient to inform a drug-associated risk of birth defects or miscarriage. In animal reproduction studies, no teratogenic effects were seen in pregnant rats and rabbits given lurasidone during the period of organogenesis at doses approximately 1.5- and 6-times, the maximum recommended human dose (MRHD) of 160 mg/day, respectively based on mg/m2 body surface area [see Data].

The estimated background risk of major birth defects and miscarriage for the indicated population(s) 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 2-4% and 15-20%, respectively.

Clinical Considerations

Fetal/Neonatal Adverse Reactions

Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs during the third trimester of pregnancy. These symptoms have varied in severity. Some neonates recovered within hours or days without specific treatment; others   required   prolonged   hospitalization.   Monitor   neonates   for   extrapyramidal   and/or withdrawal symptoms and manage symptoms appropriately.

Data

Animal Data

Pregnant rats were treated with oral lurasidone at doses of 3, 10, and 25 mg/kg/day during the period of organogenesis. These doses are 0.2, 0.6, and 1.5 times the MRHD of 160 mg/day based on mg/m 2body surface area. No teratogenic or embryo-fetal effects were observed up to 1.5 times the MRHD of 160 mg/day, based on mg/m 2.

Pregnant rabbits were treated with oral lurasidone at doses of 2, 10, and 50 mg/kg/day during the period of organogenesis. These doses are 0.2, 1.2 and 6 times the MRHD of 160 mg/day based on mg/m 2. No teratogenic or embryo-fetal effects were observed up to 6 times the MRHD of 160 mg/day based on mg/m 2.

Pregnant rats were treated with oral lurasidone at doses of 0.4, 2, and 10 mg/kg/day during the periods of organogenesis and lactation. These doses are 0.02, 0.1 and 0.6 times the MRHD of 160 mg/day based on mg/m 2. No pre- and postnatal developmental effects were observed up to 0.6 times the MRHD of 160 mg/day, based on mg/m 2.

8.2 Lactation

Risk Summary

Lactation studies have not been conducted to assess the presence of lurasidone in human milk, the effects on the breastfed infant, or the effects on milk production. Lurasidone is present in rat milk. The development and health benefits of breastfeeding should be considered along with the mother’s clinical need for lurasidone hydrochloride tablets and any potential adverse effects on the breastfed infant from lurasidone hydrochloride tablets or from the underlying maternal condition.

The  safety  and  effectiveness  of  lurasidone hydrochloride tablets 20  to  80  mg/day  for  the  treatment  of  bipolar depression in pediatric patients (10 to 17 years) was established in a 6-week, placebo-controlled clinical study in 347 pediatric patients [see Dosage and Administration ( 2.2), Adverse Reactions ( 6.1), and Clinical Studies ( 14.2)] .

The safety and effectiveness of lurasidone hydrochloride tablets has not been established in pediatric patients less than 10 years of age with bipolar depression.

Irritability Associated with Autistic Disorder

The effectiveness of lurasidone hydrochloride tablets in pediatric patients for the treatment of irritability associated with autistic disorder has not been established.

Efficacy was not demonstrated in a 6-week study   evaluating lurasidone hydrochloride tablets 20 mg/day and 60 mg/day for the treatment of pediatric patients 6 to 17 years of age with irritability associated with autistic disorder diagnosed by Diagnostic and Statistical Manual of Mental Disorders,   4th   Ed., Text Revision [DSM-IV-TR] criteria. The primary objective of the study   as measured by improvement from Baseline in the irritability subscale of the Aberrant Behavior Checklist (ABC) at Endpoint (Week 6) was not met. A total of 149 patients were randomized to lurasidone hydrochloride tablets or placebo. Vomiting occurred at a higher rate than reported in other lurasidone hydrochloride tablets studies (4/49 or 8% for 20mg, 14/51 or 27% for 60mg, and 2/49 or 4% for placebo), particularly in children ages 6 to 12 (13 out of 18 patients on lurasidone hydrochloride tablets with vomiting).

In a long-term, open-label study that enrolled pediatric patients (age 6 to 17 years) with bipolar depression, autistic disorder or another indication, from three short-term, placebo-controlled trials, 54% (378/701) received lurasidone for 104 weeks. There was one adverse event in this trial that was considered possibly drug-related and has not been reported in adults receiving lurasidone: a 10 year old male experienced a prolonged, painful erection, consistent with priapism, that led to treatment discontinuation.

In this trial, the mean increase in height from open-label baseline to Week 104 was 4.94 cm. To adjust for normal growth, z-scores were derived (measured in standard deviations [SD]), which normalize for the natural growth of children and adolescents by comparisons to age- and sex- matched population standards. A z-score change <0.5 SD is considered not clinically significant. In this trial, the mean change in height z-score from open-label baseline to Week 104 was +0.05 SD, indicating minimal deviation from the normal growth curve.

Juvenile animal studies

Adverse effects were seen on growth, physical and neurobehavioral development at doses as low as 0.2 times the MRHD based on mg/m 2. Lurasidone was orally administered to rats from postnatal days 21 through 91 (this period corresponds to childhood, adolescence, and young adulthood in humans) at doses of 3, 30, and 150 (males) or 300 (females) mg/kg/day which are 0.2 to 10 times (males) and 20 times (females) the maximum recommended adult human dose (MRHD) of  160  mg/day  based  on  mg/m 2.  The  adverse  effects  included  dose-dependent decreases in femoral length, bone mineral content, body and brain weights at 2 times the MRHD in both sexes, and  motor hyperactivity at 0.2 and 2 times the MRHD in both sexes based on mg/m 2. In females, there was a delay in attainment of sexual maturity at 2 times the MRHD, associated with decreased serum estradiol. Mortality occurred in both sexes during early post- weaning period and some of the male weanlings died after only 4 treatments at doses as low as 2 times the MRHD based on mg/m 2. Histopathological findings included increased colloid in the thyroids and inflammation of the prostate in males at 10 times MRHD based on mg/m 2and mammary gland hyperplasia, increased vaginal mucification, and increased ovarian atretic follicles at doses as low as 0.2 times the MRHD based on mg/m 2. Some of these findings were attributed to transiently elevated serum prolactin which was seen in both sexes at all doses. However,  there  were  no  changes  at  any  dose  level  in  reproductive  parameters  (fertility, conception indices, spermatogenesis, estrous cycle, gestation length, parturition, number of pups born). The no effect dose for neurobehavioral changes in males is 0.2 times the MRHD based on mg/m 2and could not be determined in females. The no effect dose for growth and physical development in both sexes is 0.2 times the MRHD based on mg/m 2.

8.5 Geriatric Use

Clinical studies with lurasidone hydrochloride tablets did not include sufficient numbers of patients aged 65 and older to determine whether or not they respond differently from younger patients. In elderly patients with psychosis (65 to 85), lurasidone hydrochloride tablets concentrations (20 mg/day) were similar to those in young subjects. It is unknown whether dose adjustment is necessary on the basis of age alone.

Elderly patients with dementia-related psychosis treated with lurasidone hydrochloride tablets are at an increased risk of death compared to placebo. Lurasidone hydrochloride tablets are not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions (5.1, 5.3)] .

8.6 Renal Impairment

Reduce  the  maximum  recommended  dosage  in  patients  with  moderate  or  severe  renal impairment (CLcr<50 mL/minute). Patients with impaired renal function (CLcr<50 mL/minute) had higher exposure to lurasidone than patients with normal renal function [ see Clinical Pharmacology (12.3)]. Greater exposure may increase the risk of lurasidone hydrochloride tablets -associated adverse reactions [ seeDosage and Administration (2.4) ]

8.7 Hepatic Impairment

Reduce the maximum recommended dosage in patients with moderate to severe hepatic impairment (Child-Pugh score ≥7). Patients with moderate to severe hepatic impairment (Child- Pugh score ≥7) generally had higher exposure to lurasidone than patients with normal hepatic function [ see Clinical Pharmacology (12.3)]. Greater exposure may increase the risk of lurasidone hydrochloride tablets -associated adverse reactions [ see Dosage and Administration (2.5)].

8.8 Other Specific Populations

No dosage adjustment for lurasidone hydrochloride tablets is required on the basis of a patient’s sex, race, or smoking status [see Clinical Pharmacology (12.3)].

9.1 Controlled Substance

Lurasidone hydrochloride tablets are not controlled substance.

9.2 Abuse

Lurasidone hydrochloride tablets have not been systematically studied in humans for its potential for abuse or physical dependence or its ability to induce tolerance. While clinical studies with lurasidone hydrochloride tablets did not reveal any tendency for drug-seeking behavior, these observations were not systematic and it is not possible to predict the extent to which a CNS-active drug will be misused, diverted and/or abused once it is marketed. Patients should be evaluated carefully for a history of drug abuse, and such patients should be observed carefully for signs of lurasidone hydrochloride tablets misuse or abuse (e.g., development of tolerance, drug-seeking behavior, increases in dose).

10.1 Human Experience

In premarketing clinical studies, accidental or intentional overdosage of lurasidone hydrochloride tablets were identified in one patient who ingested an estimated 560 mg of lurasidone hydrochloride tablets. This patient recovered without sequelae. This patient resumed lurasidone hydrochloride tablets treatment for an additional two months.

10.2 Management of Overdosage

No specific antidotes for lurasidone hydrochloride tablets are known.  In managing overdose, provide supportive care, including close medical supervision and monitoring, and consider the possibility of multiple drug involvement. If an overdose occurs, consult a Certified Poison Control Center (1-800-222-1222 or www.poison.org).

Cardiovascular monitoring should commence immediately, including continuous electrocardiographic monitoring for possible arrhythmias. If antiarrhythmic therapy is administered, disopyramide, procainamide, and quinidine carry a theoretical hazard of additive QT-prolonging effects when administered in patients with an acute overdose of lurasidone hydrochloride tablets. Similarly, the alpha-blocking properties of bretylium might be additive to those of lurasidone hydrochloride tablets, resulting in problematic hypotension.

Hypotension and circulatory collapse should be treated with appropriate measures. Epinephrine and dopamine should not be used, or other sympathomimetics with beta-agonist activity, since beta stimulation may worsen hypotension in the setting of lurasidone hydrochloride tablets -induced alpha blockade. In case of severe extrapyramidal symptoms, anticholinergic medication should be administered.

Gastric  lavage  (after  intubation  if  patient  is  unconscious)  and  administration  of  activated charcoal together with a laxative should be considered.

The possibility of obtundation, seizures, or dystonic reaction of the head and neck following overdose may create a risk of aspiration with induced emesis.

12.1 Mechanism of Action

The mechanism of action of lurasidone in the treatment of bipolar depression is unclear. However, its efficacy in bipolar depression could be mediated through  a  combination  of  central  dopamine D 2 and  serotonin  Type  2  (5HT 2A)  receptor antagonism.

12.2 Pharmacodynamics

Lurasidone is an antagonist with high affinity binding at the dopamine D 2 receptors (Ki of 1 nM) and the serotonin 5-HT 2A (Ki of 0.5 nM) and 5-HT 7 (Ki of 0.5 nM) receptors. It also binds with moderate affinity to the human α 2C adrenergic receptors (Ki of 11 nM), is a partial agonist at serotonin 5-HT 1A (Ki of 6.4 nM) receptors, and is an antagonist at the α2A adrenergic receptors (Ki of 41 nM). Lurasidone exhibits little or no affinity for histamine H 1 and muscarinic M 1 receptors (IC 50> 1,000 nM).

ECG Changes

The effects of lurasidone hydrochloride tablets on the QTc interval were evaluated in a randomized, double-blind, multiple-dose, parallel-dedicated thorough QT study in 43 patients with another indication, who were treated with lurasidone hydrochloride tablets doses of 120 mg daily, 600 mg daily and completed the study. The maximum mean (upper 1-sided, 95% CI) increase in baseline- adjusted QTc intervals based on individual correction method (QTcI) was 7.5 (11.7) ms and 4.6 (9.5) ms, for the 120 mg and 600 mg dose groups respectively, observed at 2 to 4 hours after dosing. In this study, there was no apparent dose (exposure)-response relationship.

In short-term, placebo-controlled studies in bipolar depression and another indication, no post- baseline QT prolongations exceeding 500 msec were reported in patients treated with lurasidone hydrochloride tablets or placebo.

12.3 Pharmacokinetics

Adults

The activity of lurasidone hydrochloride tablets are primarily due to the parent drug. The pharmacokinetics of lurasidone hydrochloride tablets are dose-proportional within a total daily dose range of 20 mg to 160 mg. Steady-state concentrations of lurasidone hydrochloride tablets are reached within 7 days of starting lurasidone hydrochloride tablets.

Following administration of 40 mg of lurasidone hydrochloride tablets, the mean (%CV) elimination half-life was 18 (7) hours.

Absorption and Distribution:Lurasidone hydrochloride tablets are absorbed and reaches peak serum concentrations in approximately 1-3 hours. It is estimated that 9-19% of an administered dose is absorbed. Following administration of 40 mg of lurasidone hydrochloride tablets, the mean (%CV) apparent volume of distribution was 6173 (17.2) L. Lurasidone hydrochloride tablets is highly bound (~99%) to serum proteins.

In a food effect study, lurasidone hydrochloride tablets mean C max and AUC were about 3-times and 2-times, respectively, when administered with food compared to the levels observed under fasting conditions. Lurasidone hydrochloride tablets exposure was not affected as meal size was increased from 350 to 1000 calories and was independent of meal fat content [see Dosage and Administration (2.3)] .

In clinical studies, establishing the safety and efficacy of lurasidone hydrochloride tablets, patients were instructed to take their daily dose with food [see Dosage and Administration ( 2.3)] .

Metabolism and Elimination:Lurasidone hydrochloride tablets are metabolized mainly via CYP3A4. The major biotransformation pathways are oxidative N-dealkylation, hydroxylation of norbornane ring, and S-oxidation. Lurasidone hydrochloride tablets are metabolized into two active metabolites (ID-14283 and ID-14326) and two major non-active metabolites (ID-20219 and ID-20220).  Based on in  vitro  studies, lurasidone hydrochloride tablets are not a substrate of CYP1A1, CYP1A2, CYP2A6, CYP4A11, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6 or CYP2E1 enzymes. Because lurasidone hydrochloride tablets are not a substrate for CYP1A2, smoking is not expected to have an effect on the pharmacokinetics of lurasidone hydrochloride tablets.

Transporter proteins: In vitrostudies suggest lurasidone hydrochloride tablets are not a substrate of OATP1B1 or OATP1B3, however, is probably a substrate of P-gp and BCRP. In vitrostudies indicate that lurasidone hydrochloride tablets are not expected to inhibit transporters OATP1B1, OATP1B3, OCT1, OCT2, OAT1, OAT3, MATE1, MATE2-K and BSEP at clinically relevant concentrations. Lurasidone hydrochloride tablets are not a clinically significant inhibitor of P-gp. However, it may inhibit BCRP.

Total excretion of radioactivity in urine and feces combined was approximately 89%, with about 80%  recovered  in  feces  and  9%  recovered  in  urine,  after  a  single  dose  of  [14C]-labeled lurasidone hydrochloride tablets.

Following administration of 40 mg of lurasidone hydrochloride tablets, the mean (%CV) apparent clearance was 3902 (18.0) mL/min.

Drug Interaction Studies

Effects of other drugs on the exposure of lurasidone are summarized in Figure 5. A population PK analyses concluded that coadministration of lithium 300-2400 mg/day or valproate 300-2000 mg/day with lurasidone for up to 6 weeks has minimal effect on lurasidone exposure.

And the effects of lurasidone hydrochloride tablets on the exposures of other drugs are summarized in Figure 2. A population PK analyses concluded that coadministration of lurasidone has minimal effect on lithium and valproate exposure when it is coadministered with lithium 300-2400 mg/day or valproate 300-2000 mg/day.

Pediatric Patients
Lurasidone hydrochloride tablets exposure (i.e., steady-state Cmax and AUC) in children and adolescent patients (10 to 17 years of age) was generally similar to that in adults across the dose range from 40 to 160 mg, without adjusting for body weight.
Figure 3: Impact of Other Patient Factors on Lurasidone Hydrochloride Tablets Pharmacokinetics

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis:Lurasidone increased incidences of malignant mammary gland tumors and pituitary gland adenomas in female mice orally dosed with 30, 100, 300, or 650 mg/kg/day. The lowest dose produced plasma levels (AUC) approximately equal to those in humans receiving the MRHD of 160 mg/day. No increases in tumors were seen in male mice up to the highest dose tested, which produced plasma levels (AUC) 14 times those in humans receiving the MRHD.

Lurasidone increased the incidence of mammary gland carcinomas in female rats orally dosed at 12 and 36 mg/kg/day: the lowest dose; 3 mg/kg/day is the no-effect dose which produced plasma levels (AUC) 0.4 times those in humans receiving the MRHD. No increases in tumors were seen in male rats up to the highest dose tested, which produced plasma levels (AUC) 6 times those in humans receiving the MRHD.

Proliferative and/or neoplastic changes in the mammary and pituitary glands of rodents have been observed following chronic administration of antipsychotic drugs and are considered to be prolactin-mediated [see Warnings and Precautions (5.7)].

Mutagenesis:Lurasidone did not cause mutation or chromosomal aberration when tested in vitroand in vivo test battery. Lurasidone was negative in the Ames gene mutation test, the Chinese Hamster Lung (CHL) cells, and in the in vivomouse bone marrow micronucleus test up to 2000 mg/kg which is 61 times the MRHD of 160 mg/day based on mg/m2 body surface area.

Impairment  of  Fertility:  Estrus  cycle  irregularities  were  seen  in  rats  orally  administered lurasidone   at 1.5, 15 and 150 mg/kg/day for 15 consecutive days prior to mating, during the mating period, and through gestation day 7. No effect was seen at the lowest dose of 0.1 mg/kg which is approximately 0.006 times the MRHD of 160 mg/day based on mg/m 2. Fertility was reduced only at the highest dose, which was reversible after a 14 day drug-free period. The no- effect dose for reduced fertility was approximately equal to the MRHD based on mg/m2.

Lurasidone had no effect on fertility in male rats treated orally for 64 consecutive days prior to mating and during the mating period at doses up to 9 times the MRHD based on mg/m 2.

14.2 Depressive Episodes Associated with Bipolar I Disorder

Adults

Monotherapy

The efficacy of lurasidone hydrochloride tablets, as monotherapy, was established in a 6-week, multicenter, randomized, double-blind, placebo-controlled study of adult patients (mean age of 41.5 years, range 18 to 74) who met DSM-IV-TR criteria for major depressive episodes associated with bipolar  I disorder,  with  or  without  rapid  cycling,  and  without  psychotic  features  (N=485). Patients were randomized to one of two flexible-dose ranges of lurasidone hydrochloride tablets (20 to 60 mg/day, or 80 to 120 mg/day) or placebo.

The primary rating instrument used to assess depressive symptoms in this study was the Montgomery-Asberg Depression Rating Scale (MADRS), a 10-item clinician-rated scale with total  scores  ranging  from  0  (no  depressive  features)  to  60  (maximum  score).  The primary endpoint was the change from baseline in MADRS score at Week 6. The key secondary instrument was the Clinical Global Impression-Bipolar-Severity of Illness scale (CGI-BP-S), a clinician-rated scale that measures the subject’s current illness state on a 7-point scale, where a higher score is associated with greater illness severity.

For both dose groups, lurasidone hydrochloride tablets was superior to placebo in reduction of MADRS and CGI-BP-S scores at Week 6. The primary efficacy results are provided in Table 37. The high dose range (80 to 120 mg per day) did not provide additional efficacy on average, compared to the low dose range (20 to 60 mg per day).

Adjunctive Therapy with Lithium or Valproate

The efficacy of lurasidone hydrochloride tablets, as an adjunctive therapy with lithium or valproate, was established in a 6-week, multicenter, randomized, double-blind, placebo-controlled study of adult patients (mean age of 41.7 years, range 18 to 72) who met DSM-IV-TR criteria for major depressive episodes associated with bipolar I disorder, with or without rapid cycling, and without psychotic features (N=340). Patients who remained symptomatic after treatment with lithium or valproate were randomized to flexibly dosed lurasidone hydrochloride tablets 20 to 120 mg/day or placebo.

The  primary  rating  instrument  used  to  assess  depressive  symptoms  in  this  study  was  the MADRS. The primary endpoint was the change from baseline in MADRS score at Week 6. The key secondary instrument was the CGI-BP-S scale.

Lurasidone hydrochloride tablets were superior to placebo in reduction of MADRS and CGI-BP-S scores at Week 6, as an adjunctive therapy with lithium or valproate (Table 37).

Pediatric Patients (10 to 17 years)

The efficacy of lurasidone hydrochloride tablets was established in a 6-week, multicenter, randomized, double-blind, placebo-controlled study of pediatric patients (10 to 17 years) who met DSM-5 criteria for a major depressive episode associated with bipolar I disorder, with or without rapid cycling, and without psychotic features (N=343). Patients were randomized to flexibly dosed lurasidone hydrochloride tablets 20 to 80 mg/day or placebo. At the end of the clinical study, most patients (67%) received 20 mg/day or 40 mg/day.

The primary rating scale used to assess depressive symptoms in this study was the Children’s Depression Rating Scale, Revised (CDRS-R) total score. The CDRS-R is a 17-item clinician- rated scale with total scores ranging from 17 to 113. The primary endpoint was the change from baseline in CDRS-R score at Week 6. The key secondary endpoint was the change from baseline in CGI-BP-S depression score.

Lurasidone hydrochloride tablets was superior to placebo in reduction of CDRS-R total score and CGI-BP-S depression score at Week 6. The primary efficacy results are provided in Table 38.
