Title: Efficacy and Safety of Aripiprazole in the Treatment of Acutely Relapsed Patients With Schizophrenia or Schizoaffective Disorder With Risperidone as an Active Control
Brief Summary: To evaluate the efficacy, safety and tolerability of aripiprazole in the treatment of acutely relapsed patients with diagnoses of schizophrenia or schizoaffective disorder with risperidone as an active control.


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 of schizophrenia as defined in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR; APA 2000) (Disorganized, 295.10; Catatonic, 295.20; Paranoid 295.30; or Undifferentiated, 295.90) and confirmed by the Structured Clinical Interview for DSM-IV-TR (SCID)
* Non pregnant female participants who agree to use acceptable birth control
* At entry to the study must be considered moderately ill in the opinion of the investigator
* 1 year history of Schizophrenia prior to entering the study
* At study entry participants 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 based on the investigator's clinical judgment. Participants who have never taken antipsychotic treatment may enter the study even without a history of hospitalization
* At study entry participants 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. Participants 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 participants must have experienced an exacerbation of illness within the 4 weeks prior to entering the study, leading to an intensification of psychiatric care in the opinion of the investigator. If exacerbation occurs in participants who are presently hospitalized, the participants must not have been hospitalized longer than 60 days at entry of the study

Exclusion Criteria:

* Participated in any clinical trial with any pharmacological treatment intervention for which they received a study-related medication in the 6 months prior to visit 1
* Previously completed or withdrawn from this study, or any other study investigating LY2140023 or any predecessor molecules with glutamatergic activity
* Have any known history of receiving treatment with clozapine at any dose, as determined at baseline
* Have received treatment with a depot formulation of an antipsychotic medication within the 6 months prior entering the study
* Participants who are currently suicidal
* Females who are pregnant, nursing, or who intend to become pregnant within 30 days of completing the study

* Participants are excluded if their biological father, mother, brother, sister, or child has a history of idiopathic epilepsy
* Within 1 year of study enrollment, participants have a history of central nervous system infection, uncontrolled migraine, transient ischemic attack (TIA), or head trauma with loss of consciousness or a post-concussive
* Participants are excluded if they have a lifetime history of any of the following:

  * head trauma, stroke, or central nervous system (CNS) infection with persistent neurological deficit (focal or diffuse);
  * brain surgery;
  * an electroencephalogram with paroxysmal (epileptiform) activity, or
  * brain structural lesion, including developmental abnormalities, as determined by examination or previous neuroimaging studies that are consistent with a diagnosable neurological disease or syndrome
* Electroconvulsive therapy (ECT) within 3 months of entering the study or who will have ECT at any time during the study
* Leukopenia
* Medical history of Human Immunodeficiency Virus positive (HIV+) status
* Higher than normal blood prolactin levels
* Certain electrocardiogram results
C: 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.
