Arm && Interventions

Group	Intervention	Description
Paliperidone Palmitate 6 month(PP6M)	PP6M injection Dose 1	Participants who enter the this open-label extension study immediately after completing Double-blind Phase Study R092670PSY3015 (previous study) will receive Paliperidone Palmitate 6 month (PP6M) intramuscular (IM) injections, dose will be selected based on the unblinded dose level ("moderate" or "higher") that the participant received during previous study. Participants in the "moderate" dose level will receive PP6M Dose 1 and "higher" dose level will receive PP6M Dose 2 during the open-label extension. The PP6M dose level may be adjusted (to Dose 1 or Dose 2) for every 6 month at Visits 3, 5, and 7, based on clinical judgment. Participants who enter this open-label extension study later (up to 3 months after they complete previous study) and were on a moderate or higher dose of PP3M (350 or 525 mg eq.) or PP1M (100 or 150 mg eq.) will receive initial dose of PP6M IM injection (Dose 1 or Dose 2) for every 6 months.
Paliperidone Palmitate 6 month(PP6M)	PP6M injection Dose 2	Participants who enter the this open-label extension study immediately after completing Double-blind Phase Study R092670PSY3015 (previous study) will receive Paliperidone Palmitate 6 month (PP6M) intramuscular (IM) injections, dose will be selected based on the unblinded dose level ("moderate" or "higher") that the participant received during previous study. Participants in the "moderate" dose level will receive PP6M Dose 1 and "higher" dose level will receive PP6M Dose 2 during the open-label extension. The PP6M dose level may be adjusted (to Dose 1 or Dose 2) for every 6 month at Visits 3, 5, and 7, based on clinical judgment. Participants who enter this open-label extension study later (up to 3 months after they complete previous study) and were on a moderate or higher dose of PP3M (350 or 525 mg eq.) or PP1M (100 or 150 mg eq.) will receive initial dose of PP6M IM injection (Dose 1 or Dose 2) for every 6 months.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Relapse	Up to Day 730	Number of participants with relapse were reported. Relapse is defined as one or more of the following: a) Psychiatric hospitalization for schizophrenia (involuntary or voluntary admission to a psychiatric hospital for decompensation of the participant's schizophrenic symptoms); b) Emergency Department/Room/Ward visit due to a worsening of the participant's symptoms of schizophrenia, but a psychiatric hospitalization does not occur; c) The participant inflicts deliberate self-injury or exhibits violent behaviour resulting in suicide, clinically significant injury to him/herself or another person, or significant property damage; d) The participant has suicidal or homicidal ideation and aggressive behaviour that is clinically significant (in frequency and severity) in the investigator's judgment.
Number of Participants With Treatment-emergent Adverse Events (TEAEs)	Up to Day 730	An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/ biological agent under study. TEAEs are those events if they started after administration of the first dose and until 183 days after the last dose of study medication.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Clinical Global Impression-Severity (CGI-S) Scale Score	Baseline up to Day 730	Change from baseline in CGI-S scale score was reported. CGI-S is defined as clinician-rated scale that assesses the severity of mental illness on a scale of 0 to 7. Considering total clinical experience, a participant was assessed on severity of mental illness at the time of rating according to:1: normal, not at all ill; 2: borderline mentally ill; 3: mildly ill; 4: moderately ill; 5: markedly ill; 6: severely ill; 7: among the most extremely ill participants. A higher score implies a more severe condition.
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score	Baseline up to Day 730	Change from baseline in PANSS total score were reported. The neuropsychiatric symptoms of schizophrenia were assessed using the 30-item PANSS scale, which provides a total score (sum of the scores for all 30 items) and scores for 3 subscales: the 7-item positive-symptom (P) subscale, the 7-item negative-symptom (N) subscale, and the 16-item general-psychopathology symptom (G) subscale. Each item is rated on a scale of 1 (absent) to 7 (extreme). The PANSS total score ranges from 30 (absent disease)-210 (more severe neuropsychiatric symptoms of schizophrenia).
Change From Baseline in Personal and Social Performance (PSP) Scale Score	Baseline up to Day 730	Change from baseline in PSP scale score was reported. The PSP scale assesses degree of a participant's dysfunction within 4 domains of behavior: 1) socially useful activities, 2) personal and social relationships, 3) self-care, and 4) disturbing and aggressive behavior. Each domain was assessed on a 6-point scale, from 1 (absent) to 6 (very severe) (1 = absent, 2 = mild, 3 = manifest, 4 = marked, 5 = severe, and 6 = very severe). PSP total score was calculated as sum of all the domain scores and ranges from 1 to 100. Participants with score of 71 to 100 had mild degree of difficulty; from 31 to 70, varying degrees of disability; less than or equal to 30, functioning so poorly as to require intensive supervision. Higher score indicates better performance.
