Brief Summary:
The purpose of this study is to assess the safety of JNS007ER 3-12 mg once daily in patients with schizophrenia over a long term period.

Condition or disease Intervention/treatment Phase
Schizophrenia Drug: Paliperidone extended-release (JNS007ER) Phase 3

Detailed Description:

This is a 48-week, multicenter, open-label (all people know the identity of the intervention), non-controlled, arbitrary-dose study. The patients included in this study are those who participated in the preceding double-blind (neither physician nor patient knows the treatment that the patient receives) comparative trial (study JNS007ER-JPN-S31) of JNS007ER and completed the study, or those who remained in the study up to the evaluation at 2 weeks and discontinued the study after that for insufficient treatment efficacy. The study will assess the safety of JNS007ER in the clinical recommended dose range in a long term treatment. The dosage will be started at 6 mg/day, and it can be increased or decreased 3 mg at a time depending on the patient's symptom within the range of 3 mg/day to 12 mg/day. For dose adjustments, the investigator will evaluate the psychiatric symptoms before defining the dose change.

Detailed Description: Extended description of the protocol, including more technical information (as compared to the Brief Summary) if desired. Do not include the entire protocol; do not duplicate information recorded in other data elements, such as eligibility criteria or outcome measures.

Arm Intervention/treatment
Experimental: Paliperidone extended-release (JNS007ER) Drug: Paliperidone extended-release (JNS007ER)
Type= range, unit= mg, number= 3-12, form= tablet, route= oral use. JNS007ER within the range of 3, 6, 9 and 12 mg will be orally administered once daily for 48 weeks.

Primary Outcome Measures :
  1. Incidence of Adverse Events [ Time Frame: 48 weeks ]
    The incidence of adverse events was measured by the percentage of patients who presented one or more adverse events.

Secondary Outcome Measures :
  1. Change From Baseline in Positive and Negative Syndrome Scale (PANSS) [ Time Frame: Baseline, Week 48 ]
    PANSS is a medical scale that assesses various symptoms of schizophrenia. The symptoms are rated on a 7-point scale from 1 (absent) to 7 (extreme psychopathology). The total score is the sum of all 30 PANSS items, with a range of 30 (absent) to 210 (extreme ill).

  2. Change From Baseline in Clinical Global Impression - Severity (CGI-S) [ Time Frame: Baseline, Week 48 ]
    The CGI-S rating scale is a 7 point global assessment that measures the clinician's impression of the severity of illness exhibited by a patient. A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill patients".
