Study Endpoints

Primary Endpoints

Part-2 (Disease Progression): Time to First Treatment Failure
From Day 1 up to 9 Months

Treatment failure is defined as the time from participant's randomization to first treatment failure, which was a composite endpoint consisting of any of the following: 1) Psychiatric hospitalization due to worsening symptoms; 2) Any deliberate self-injury, suicidal ideation or behavior, homicidal ideation or violent behavior that is clinically significant and needs immediate intervention as determined by the study physician; 3) New arrest/incarceration; 4) Discontinuation of antipsychotic treatment due to inadequate efficacy as determined by the study physician; 5) Discontinuation of antipsychotic treatment due to safety or tolerability as determined by the study physician; 6) Treatment supplementation with another antipsychotic due to inadequate efficacy as determined by the study physician; 7) Increase in the level of psychiatric services in order to prevent imminent psychiatric hospitalization as determined by the study physician.

Part 3 (Extended Disease Progression [EDP]): Change From Baseline in Cognition as Measured by the MATRICS Consensus Cognitive Battery (MCCB) Composite Score
Baseline and 18 Months

The MATRICS Consensus Cognitive Battery is an instrument that contains 10 tests to measure cognitive performance in 7 cognitive domains: speed processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving, and social cognition. The composite score combines the individual scores of the 10 tests and scores them on a normative scale to derive a T-score and composites scores. The range of T-scores for a normal control population is between 0 to 100 with a mean of 50 and standard deviation of 10. Higher scores indicate better cognitive functioning.

Part 3 (Disease Modification): Change From Baseline in Cognition as Measured by the MATRICS Consensus Cognitive Battery (MCCB) Composite Score
Baseline and Day 260

The MATRICS Consensus Cognitive Battery is an instrument that contains 10 tests to measure cognitive performance in 7 cognitive domains: speed processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving, and social cognition. The composite score combines the individual scores of the 10 tests and scores them on a normative scale to derive a T-score and composites scores. The range of T-scores for a normal control population is between 0 to 100 with a mean of 50 and standard deviation of 10. Higher scores indicate better cognitive functioning.

Double Blind (DB) Phase: Median Time to Relapse
DB Baseline (Day 1 of Week 15) up to interim analysis data cut-off (24 August 2012) (Approximately 1 year)

A relapse is defined as any one of the following: 1. involuntary or voluntary psychiatric hospitalization 2. deliberate self-injury or violent behavior; 3. Suicidal or homicidal ideation and clinically significant aggressive behavior; 4. 25 percent (%) increase in Positive and Negative Syndrome Scale (PANSS) total score for 2 consecutive assessments for participants whose score was greater than 40 at randomization, or a 10-point increase for participants who scored less than or equal to (≤) 40 at randomization; 5. increase for 2 consecutive assessments in PANSS items (delusions, conceptual disorganization, hallucinatory behavior, suspiciousness, hostility or uncooperativeness) to greater than or equal to (≥) 5 for participants who scored ≤3 at randomization, or to ≥6 for participants with initial score of 4. Independent Data Monitoring Committee performed ongoing safety monitoring during double-blind treatment and conducted the interim analysis after 61 relapse events had taken place.

Change From Baseline in the Positive and Negative Syndrome Scale (PANSS) Total Score at Day 56
Baseline and Day 56

The PANSS is a 30-item scale with each item rated on a scale of 1 (absent) to 7 (extreme psychopathology), designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and poor impulse control. The PANSS total score consists of the sum of all 30 PANSS items and ranges from 30 to 210. Higher scores indicate worsening.

Change in the PANSS Total Score From Baseline to the Last Postrandomization Assessment in the Double-blind Period of the Study.
6 weeks

The Positive and Negative Syndrome Scale (PANSS) measures the severity of psychotic symptoms of schizophrenia. Scores range from 30 to 210, where 30=best and 210=worst. The change in PANSS total score for all eligible subjects was measured from the beginning of the study to the end.

Number of Participants With Treatment Response Based on Total PANSS Scale Score
Day 42 or early discontinuation

Response was defined as decrease of at least 30 percent in total Positive and Negative Syndrome Scale (PANSS) score from Baseline to endpoint of core phase (which is, Day 42 or early discontinuation). The PANSS is a 30-item scale designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, \& poor impulse control. The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score consists of sum of all 30 PANSS items \& ranges from 30 to 210. Higher scores indicate worsening.

The Number of Participants Who Experienced Adverse Events as a Measure of Safety and Tolerability
Up to 2 years

A serious adverse event as defined by the International Conference on Harmonisation (ICH) is any untoward medical occurrence that at any dose results in death, is life-threatening (the subject was at risk of death at the time of the even; it does not refer to an event that hypothetically might have caused death if it were more severe), requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, or is a congenital anomaly/birth defect.

The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score consists of the sum of all 30 PANSS items and ranges from 30 to 210. Higher scores indicate worsening. Data for two groups is presented here, based on the reason to switch: lack of efficacy and lack of tolerability, compliance or other who switched from other previous antipsychotic drugs to paliperidone.

The PANSS provides a total score and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each item scored on a scale of 1 (absent) to 7 (extreme). The total score ranges from 30 to 210 and higher score indicates greater severity.

Incidence of Adverse Events
48 weeks

The incidence of adverse events was measured by the percentage of patients who presented one or more adverse events.

Time to Recurrence of Any Mood Symptoms (Manic or Depressive) Associated With Bipolar I Disorder
Date of randomization into the maintenance phase until the first occurrence of recurrence of any symptoms or discontinuation from the study, assessed over a period of 41 months.

Time to first recurrence of any mood symptoms (ie, manic or depressive) associated with bipolar I disorder during the maintenance phase, after maintaining clinical stability during continued treatment with paliperidone ER over a period of 15 weeks. The time period was from occurrence of acute manic or mixed episode to Week 15. This outcome was measured using combination of various scales, hospitalization for any mood symptoms, use of any medicines for an mood episode and clinical events suggestive of recurrent mood episode associated with bipolar I disorder.
