Title: A Randomized, Double Blind Study to Evaluate the Efficacy and Safety of Two Atypical Antipsychotics vs. Placebo in Patients With an Acute Exacerbation of Either Schizophrenia or Schizoaffective Disorder
Brief Summary: A study to evaluate the efficacy and safety of two atypical antipsychotics vs. placebo in patients with an acute exacerbation of either schizophrenia or schizoaffective disorder


Options:
A: Inclusion Criteria:

* Currently suffering from an acute exacerbation of schizophrenia. Caregiver required.

Exclusion Criteria:

* Have an uncontrolled, unstable medical condition. Have any other psychiatric disorder other than schizophrenia as a primary diagnosis.
B: Inclusion Criteria:

* Diagnosis: Schizophrenia or schizoaffective disorder, in an acute relapse.
* Duration of present episode/relapse: Randomization to this study occurred no more than four weeks following the day of initiation of any treatment for the last episode/relapse.
* Age: 18 to 65 years.
* Gender: Males and females (females of childbearing potential had a negative serum pregnancy test from screening visit, used acceptable contraception, and were not pregnant or lactating).
* Response to previous antipsychotic agents: Patients had responded to previous antipsychotic medication
* Current antipsychotic treatment: Prior to beginning the placebo-washout, patients had not been treated with a long-acting antipsychotic within the time required for one cycle of treatment with that long-acting antipsychotic, plus one week. Patients who had been treated with a long-acting antipsychotic within less than this time period might be enrolled in the study, providing they were judged by the investigator to be clearly clinically deteriorating.
* Positive and Negative Syndrome Scale scores: Patients had a total PANSS score of at least 60. In addition, patients had a score of at least 4 on any two of the four PANSS items that constitute a psychotic items subscale.
* Compliance with the protocol: Patients were rated reliably on the battery of psychiatric and movement rating scales required by the protocol.
* Informed Consent: Patients eligible to enter the study signed an informed consent form prior to the initiation of any study procedures.

Exclusion Criteria:

* Patients who, in the opinion of the investigator, had serious suicidal ideation or patients who were liable to serious suicide attempt, by clinical judgment.
* Patients presented with a first episode of schizophrenia or schizoaffective disorder
* Patients who had any of the following neurological diagnoses, whether under treatment or not, whether stable or not: migraine, epilepsy, Parkinson's disease, Alzheimer's disease, multiple sclerosis, residual of stroke, transient cerebral ischemic attacks, 'cerebral palsy' or any condition that required intermittent or maintenance treatment, or which was manifested by any abnormality on neurological examination.
* Patients who continued to take, or who potentially needed to take, during the double-blind portion of this study, any of the following concomitant medications, which could cause unwanted drug-to-drug interactions or which could confound the analysis of antipsychotic effectiveness of the randomly assigned study drug: carbamazepine, valproic acid or sodium valproate or divalproate sodium, lithium carbonate or lithium citrate.
* Patients who failed to withdraw from fluoxetine treatment at least 28 days prior to screening, if on treatment with fluoxetine.
* Patients with any gastrointestinal resection, stomach stapling, or any other condition that may impair the absorption of the study medication.
* Patients who had positive result in the urine screen for drugs of abuse (except for cannabis or medically-prescribed analgesics or benzodiazepines.)
* Patients who met the DSM-IV criteria for psychoactive substance dependence or patients with a history of substance or alcohol dependence within one month prior to the beginning of the study.
* Patients had any somatic condition whose symptoms or physical signs could be misinterpreted as signs or symptoms of schizophrenia or as adverse effects from antipsychotic medications.
* Patients with any acute or unstable medical condition.
* Patients who had taken an investigational drug within the four weeks, which preceded the start of placebo washout.
* Patients who were treatment-resistant.
* Patients who continued to take, or who potentially needed to take, during this study, any medication or substance that is known to be an inhibitor of the microsomal enzyme CYP2D6, or an inhibitor or a substrate of the microsomal enzyme CYP3A4.
C: Inclusion Criteria:

* Diagnosis of schizophrenia as defined in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR); and confirmed by the Structured Clinical Interview for DSM-IV-TR (SCID)
* Non pregnant female patients who agree to use acceptable birth control
* Participants must be considered moderately ill in the opinion of the investigator
* Patients in whom a modification of antipsychotic medication or initiation of antipsychotic medication is acutely indicated in the opinion of the investigator
* Willing to participate in a minimum of 2 weeks of inpatient hospitalization
* One year history of Schizophrenia prior to entering the study
* At study entry patients with a history of antipsychotic treatment must have a lifetime history of at least one hospitalization for the treatment of schizophrenia, not including the hospitalization required for study. Patients who have never taken antipsychotic treatment may enter the study even without a history of hospitalization.
* At study entry patients with a history of antipsychotic treatment must have a history of at least one episode of illness exacerbation requiring an intensification of treatment intervention or care in the last 2 years, not including the present episode of illness. Patients who have never taken antipsychotic treatment may enter the study without a past history of illness exacerbation and intensification of treatment in the last 2 years.
* At study entry patients must have experienced an exacerbation of illness within the 2 weeks prior to entering the study, leading to an intensification of psychiatric care in the opinion of the investigator. If exacerbation occurs in patients who are presently hospitalized, the patient must not have been hospitalized longer than 60 days at entry of the study.
* Patients must be considered reliable and have a level of understanding sufficient to perform all tests and examinations required by the protocol, and be willing to perform all study procedures

Exclusion Criteria:

* Patients who have a history of inadequate clinical response to antipsychotic treatment for schizophrenia
* Diagnosis of substance dependence or substance abuse within 6 month of study entry
* Diagnosis of substance-induced psychosis within 7 days of study entry
* Currently enrolled in, or discontinued within 6 months from a clinical trial involving an investigational product or unapproved use of a drug or device
* Participated in any clinical trial with any pharmacological treatment intervention for which they received a study-related medication in the 6 months prior to study entry
* Previously completed or withdrawn from this study, or any other study investigating LY2140023 or any predecessor molecules with glutamatergic activity
* Treatment with clozapine at doses greater than 200 mg daily within 12 months prior to entering the study, or who have received any clozapine at all during the month before study entry
