• Within 5th to 95th percentile for gender specific weight-for-age and height-for-age Growth Charts from National Center for Health Statistics.

• In good physical health on the basis of medical history, physical examination, and laboratory screening.

• Females who participate in this study:

are unable to become pregnant (eg, premenarchal, surgically sterile, etc.); -OR-

practices true abstinence (consistent with lifestyle) and must agree to remain abstinent from signing informed consent to at least 30 days after the last dose of study drug has been taken;

-OR-

are sexually active and willing to use a medically effective method of birth control (e.g., male using condom and female using condom, diaphragm, contraceptive sponge, spermicide, contraceptive pill, or intrauterine device) from signing informed consent to at least 7 days after the last dose of study drug has been taken.

• Males must be willing to remain sexually abstinent (consistent with lifestyle) or use an effective method of birth control (eg, male using condom and female using condom, diaphragm, contraceptive sponge, spermicide, contraceptive pill, or intrauterine device) from signing informed consent to at least 30 days after the last dose of study drug has been taken.

• In the judgement of the clinician, the subject has an acute exacerbation of psychotic symptoms (no longer than 2 months in duration) and marked deterioration of function from baseline (by history) or, the subject has been hospitalized for the purpose of treating an acute psychotic exacerbation for 2 consecutive weeks or less immediately before screening.

• In the judgment of the investigator, the subject is able to swallow the size and number of study drug tablets specified per protocol.

• Willing and able to adhere to protocol-specified meal requirements during dosing.

Exclusion Criteria:

• Has an Axis I or Axis II diagnosis other than schizophrenia that has been the primary focus of treatment within 3 months of screening.

• Has a history or current diagnosis of mental retardation, neuroleptic malignant syndrome, or any neurologic disorder, or severe head trauma.

• Lifetime history of human immunodeficiency virus (HIV) positive or acquired immune deficiency syndrome (AIDS), or history of Hepatitis B or C.

• Any of the following:

Documented history of chromosomal disorder with developmental impairment (ie, trisomy chromosome 21; 22q11 deletion syndrome).

Evidence of any chronic organic disease of the CNS such as tumors, inflammation, active seizure disorder, vascular disorder, potential CNS related disorders that might occur in childhood- eg, Duchenne Muscular dystrophy, myasthenia gravis, or other neurologic or serious neuromuscular disorders. In addition, subjects must not have a history of persistent neurological symptoms attributable to serious head injury. Past history of febrile seizure, drug-induced seizure, or alcohol withdrawal seizure is not exclusionary.

• PANSS total scores ≥ 120 at screening or Baseline.

• Exhibits evidence of moderate or severe extrapyramidal symptoms, dystonia, tardive dyskinesia, or any other moderate or severe movement disorder. Severity to be determined by the investigator.

• Lifetime history of electroconvulsive therapy (ECT).

• Resistant to antipsychotic treatment based on at least two different prior adequate trials (ie, adequate dose and duration) of an antipsychotic agent within the current episode of schizophrenia.

• Clinically significant neurological, metabolic (including type 1 diabetes), hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, carcinoma, and/or urological disorder that would pose a risk to the subjects if they were to participate in the study or that might confound the results of the study.

Note: Active medical conditions that are minor or well-controlled are not exclusionary if they do not affect risk to the subject or the study results. In cases in which the impact of the condition upon risk to the subject or study results is unclear, the Medical Monitor should be consulted. Any subject with a known cardiovascular disease or condition (even if controlled) must be discussed with the Medical Monitor during screening.

• Has a history of malignancy < 5 years prior to signing the informed consent.

• Clinically significant finding(s) on physical examination determined by the investigator to pose a health concern to the subject while on study.

• Clinically relevant abnormal laboratory values or abnormal vital sign values/findings.

Note: If any laboratory results are outside the normal range, the site may have the subject retested. If upon retesting the value remains outside the normal range, the significance of this value must be discussed with the Medical Monitor for enrollment consideration.

• A history or presence of abnormal ECG, which in the investigator's opinion is clinically significant. Abnormal screening ECGs will be centrally over-read, and eligibility will be determined based on the over-read.

• Presence or history (within the last year) of a medical or surgical condition (eg, gastrointestinal disease) that might interfere with the absorption, metabolism, or excretion of orally administered lurasidone.

• Clinically significant alcohol abuse/dependence or drug abuse/dependence based on DSM-IV-TR criteria within the last 6 months prior to screening.

• Positive test results at screening or Baseline for:

1. Urine drugs of abuse (amphetamines, barbiturates, benzodiazepines, cocaine, opiates, phencyclidine, cannabinoids, and methadone). A positive test for amphetamines, barbiturates, opiates, benzodiazepines or methadone may not result in exclusion of subjects if the investigator determines that the positive test is as a result of taking prescription medicine(s) as prescribed. In the event a subject tests positive for cannabinoids (tetrahydrocannabinol) or alcohol, the investigator will evaluate the subject's ability to abstain from prohibited substances during the study. If in the investigator's clinical judgment the subject will abstain, the subject may be enrolled after consultation with the Medical Monitor.

2. Pregnancy test.

• Females who are pregnant, lactating, or likely to become pregnant during the study.

• Participated in another interventional clinical trial or receiving an investigational product within 30 days prior to randomization.

• Donation of whole blood within 60 days prior to randomization.

• At screening or Baseline the subject answers "yes" to "Suicidal Ideation" Items 4 or 5 on the C-SSRS.

• Subject is considered by the investigator to be at imminent risk of suicide or injury to self, others, or property during the study. Subject has a history of one or more serious suicide attempts (based on the investigator's judgment) in the 3 months prior to screening. Subjects determined to be at risk of suicide or injury, as assessed by the investigator at screening, will be referred for further psychiatric evaluation.

• Adhering to a special diet for the 28 days prior to drug administration (eg, liquid, protein, raw food diet).

• Subject is planning to move during the study, is chronically homeless, or is unable to attend all planned study visits. The Medical Monitor will be consulted for individual cases, as needed.

• Demonstrates a decrease (improvement) of > 25% in the PANSS score between screening and Baseline visits.

• Subject with newly diagnosed Type 2 diabetes during screening. A subject with Type 2 diabetes is eligible for study inclusion if considered clinically stable, which is defined as:

Random (non-fasting) screening glucose is < 200 mg/dl (11.1 mmol/L); and If ≥ 200 mg/dL (11.1 mmol/L) must be retested in a fasted state. Retested fasted value cannot be ≥ 126 mg/dL.
