Primary Outcome Measures:
  • Change From Baseline in Clinical Global Impression Severity (CGI-S) Scale at Week 10 [ Time Frame: Baseline, Week 10 ]
    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 participant. 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 participants". Higher scores indicate worsening .

  • Change From Baseline in Personal and Social Performance (PSP) Total Score at Week 2 [ Time Frame: Baseline, Week 2 ]
    The PSP scale assesses degree of a participant's dysfunction within 4 domains of behavior: socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behavior. Score ranges from 1 to 100, divided into 10 equal intervals to rate degree of difficulty (1, absent to 6, very severe) in each of the 4 domains. Based on 4 domains there will be 1 total score. Participants with score of 71 to 100 have 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.

  • Change From Baseline in Personal and Social Performance (PSP) Total Score at Week 6 [ Time Frame: Baseline, Week 6 ]
    The PSP scale assesses degree of a participant's dysfunction within 4 domains of behavior: socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behavior. Score ranges from 1 to 100, divided into 10 equal intervals to rate degree of difficulty (1, absent to 6, very severe) in each of the 4 domains. Based on 4 domains there will be 1 total score. Participants with score of 71 to 100 have 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.

  • Change From Baseline in Personal and Social Performance (PSP) Total Score at Week 10 [ Time Frame: Baseline, Week 10 ]
    The PSP scale assesses degree of a participant's dysfunction within 4 domains of behavior: socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behavior. Score ranges from 1 to 100, divided into 10 equal intervals to rate degree of difficulty (1, absent to 6, very severe) in each of the 4 domains. Based on 4 domains there will be 1 total score. Participants with score of 71 to 100 have 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.


Enrollment: 40
Study Start Date: August 2009
Study Completion Date: September 2010
Primary Completion Date: September 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Paliperidone Extended Release (ER)
Paliperidone ER 3 milligram (mg) or 6 mg or 9 mg or 12 mg oral tablets depending on investigator's discretion once daily for 10 weeks
Drug: Paliperidone extended release (ER)
Paliperidone ER 3 milligram (mg) or 6 mg or 9 mg or 12 mg oral tablets depending on investigator's discretion once daily for 10 weeks

Detailed Description:
This is an open-label (all people know the identity of the intervention), non-randomized (the study drug is not assigned by chance) study to evaluate the efficacy and safety of paliperidone ER in adult Thai schizophrenia participants. The study consists of a screening phase and an open-label treatment phase. Study duration will be 10 weeks and participants can either be inpatient or outpatient. The recommended paliperidone ER starting and maintenance dose will be 6 milligram (mg) per day for most participants. Throughout the study, flexible dosing ranging from 3 to 12 mg per day may be used at the discretion of the investigator. Throughout the study, participants will be evaluated for efficacy using clinician rating (Clinical and Global Impressions-Severity [CGI-S] scale, and Personal and Social Performance Scale [PSP]) scales. Safety of the participants will be monitored.
