Percentage of Participants in Categories of Change in Weight From Study P06124 Baseline to Final Assessment
For each participant, change in weight from preceding 6-week double-blind Study P06124 baseline to the final assessment of extension study P06125 was determined (calculated as final assessment value minus baseline value). Final assessment was last evaluation of participant in study, whether participant completed or did not complete study. Participants were allocated to categories of percentage change from defined baseline to final assessment.

Number of Participants With Extrapyramidal Symptoms
This measure reports the overall number of participants with any of a group of adverse events that were defined to represent extrapyramidal symptoms. The number of participants with each of the individual adverse events within this definition is also presented, for terms that occurred in at least one participant. For this measure, all adverse event terms within the Medical Dictionary for Regulatory Activities (MedDRA) Standardized MedDRA Query (SMQ) for "extrapyramidal syndrome" were treated as extrapyramidal symptoms.
Change From Study P06124 Baseline in Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS) Total Score at Endpoint
Change in DIEPSS Total Score from preceding 6-week double-blind Study P06124 baseline to endpoint assessment of extension study P06125 was determined (calculated as endpoint value minus baseline value). Endpoint assessment was last evaluation of participant for this measure in study, whether participant completed or did not complete study. DIEPSS is a scale, rated by the investigator or rater appointed by the investigator, used to evaluate the severity of drug induced extrapyramidal symptoms occurring during antipsychotic drug treatment. It consists of 9 items: Items 1 through 8 assess individual symptoms; Item 9 is an assessment of global severity. Items 1 through 8 are classified into 4 categories of parkinsonism, akathisia, dystonia and dyskinesia. Each item is rated from 0 (none, normal) to 4 (severe). The Total Score is the sum of scores on Items 1 through 8, with a range from 0 (normal) to 32 (severe). Negative values of change from baseline represent improvement in symptoms.

Number of Participants With Serious Adverse Events (AEs)
An AE is defined as any untoward medical occurrence in a participant administered study drug and which does not necessarily have to have a causal relationship with the study drug. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with study drug administration, whether or not considered related to study drug. A serious AE (SAE) is any AE occurring at any dose that results in death, is life-threatening, results in hospitalization or prolongation of hospitalization, results in persistent or significant disability/incapacity, or is a congenital anomaly/birth defect. In addition, an important medical event that may not result in death, be life-threatening, or require hospitalization may be considered an SAE when it may jeopardize the participant and may require medical or surgical intervention to prevent one of the outcomes listed in this definition.
Number of Participants With Non-serious AEs
An AE is defined as any untoward medical occurrence in a participant administered study drug and which does not necessarily have to have a causal relationship with the study drug. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with study drug administration, whether or not considered related to study drug. This measure presents the number of participants with at least one AEs that was non-serious (i.e., was not determined to be an SAE).

Number of Participants Who Took Antiparkinsonian Drugs
This measure presents the number of participants who used antiparkinsonian drugs started on or after the start of study treatment in extension study P06125. Antiparkinsonian drugs were defined as those categorized into the N04 code (antiparkinson drugs) of the World Health Organization (WHO) Anatomical Therapeutic Chemical (ATC) classification system.
Median Time to Loss of Effect in Responders
Median time to loss of effect from P06125 extension study baseline was estimated using Kaplan-Meier product-limit method. Result reported in Responders, participants with ≥30% decrease from study P06124 baseline in Positive and Negative Syndrome Scale (PANSS, schizophrenia symptom scale) Total Score at the end of study P06124. Investigator or subinvestigator was to determine whether the study drug failed to maintain effect based on occurrence of any of the following: 1) Increase in PANSS Total Score ≥30% from P06125 extension study baseline, 2) Determination that participant's schizophrenic symptomatology had deteriorated requiring one or more of defined interventions (add new antipsychotic drug, increase in level of psychiatric outpatient care, or hospitalization/increase in level of hospitalization for psychiatric need), 3) Clinical Global Impression-Severity (CGI-S) score ≥6, 4) Discontinuation from study because of lack of efficacy, 5) AE/SAE of worsening of schizophrenia.
Median Time to Loss of Effect in Non-Responders
Median time to loss of effect from P06125 extension study baseline was estimated using Kaplan-Meier product-limit method. Result reported in Non-Responders, participants without ≥30% decrease from study P06124 baseline in PANSS Total Score at the end of study P06124. Investigator or subinvestigator was to determine whether the study drug failed to maintain effect based on occurrence of any of the following: 1) Increase in PANSS Total Score ≥30% from P06125 extension study baseline, 2) Determination that participant's schizophrenic symptomatology had deteriorated requiring one or more of defined interventions (add new antipsychotic drug, increase in level of psychiatric outpatient care, or hospitalization/increase in level of hospitalization for psychiatric need), 3) Clinical Global Impression-Severity (CGI-S) score ≥6, 4) Discontinuation from study because of lack of efficacy, 5) AE/SAE of worsening of schizophrenia.
