About this study

Official title: An Open Label, Prospective, Non-comparative Study to Evaluate Flexible Dose of Paliperidone Extended-Release and Clinical Response in the Treatment of Subjects With Schizophrenia

The purpose of this study is to evaluate the efficacy of paliperidone extended-release (ER) in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self).

Read the detailed description

This is an open-label (all people know the identity of the intervention), multi-centric (conducted in more than one center), prospective (study following participants forward in time), single arm, and non-comparative study of paliperidone Extended Release(ER) in participants with schizophrenia. The total study duration will be approximately of 104 weeks per participant. The study consists of following parts: Screening (that is, 14 days before study commences on Day 1); acute Treatment phase (single-oral dose of paliperidone for 12 weeks, dose ranging from 3 to 12 milligram); Extension phase 1 (12 weeks) and Maintenance treatment which will be followed by additional Extension phase 2 and long-term maintenance treatment. Efficacy of the participants will primarily be evaluated by Clinical Global Impression-Improvement (CGI-I) scale score. Participants' safety will be monitored throughout the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants Assessed as Very Much Improved or Much Improved Based on Clinical Global Impression-Improvement (CGI-I) Scale - Intent-to-treat (ITT) Population

    The CGI-I is a 7-point scale that requires the clinician to assess how much the participant's illness has improved or worsened relative to a baseline state at the beginning of the intervention and rated as: 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse.

    Measured: Week 12

  2. Percentage of Participants Assessed as Very Much Improved or Much Improved Based on Clinical Global Impression-Improvement (CGI-I) Scale - Per Protocol (PP) Population

    The CGI-I is a 7-point scale that requires the clinician to assess how much the participant's illness has improved or worsened relative to a baseline state at the beginning of the intervention and rated as: 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse.

    Measured: Week 12

Secondary outcomes (10)
  1. Personal and Social Performance (PSP) Scale Score - Intent-to-treat (ITT) Population

    The PSP scale assesses the degree of dysfunction within 4 domains of behavior: socially useful activities, personal and social relationships, self-care and disturbing and aggressive behavior. The score ranges from 1 to 100, divided into 10 equal intervals to rate the degree of difficulty (1, absent to 6, very severe) in each of the 4 domains. Participants with a score of 71 to 100 have a mild degree of difficulty; from 31 to 70, varying degrees of disability; less or equal to 30, functioning so poorly as to require intensive supervision.

    Measured: Baseline, Week 4 and 12

  2. Personal and Social Performance (PSP) Scale Score - Per Protocol (PP) Population

    The PSP scale assesses the degree of dysfunction within 4 domains of behavior: socially useful activities, personal and social relationships, self-care and disturbing and aggressive behavior. The score ranges from 1 to 100, divided into 10 equal intervals to rate the degree of difficulty (1, absent to 6, very severe) in each of the 4 domains. Participants with a score of 71 to 100 have a mild degree of difficulty; from 31 to 70, varying degrees of disability; less or equal to 30, functioning so poorly as to require intensive supervision.

    Measured: Baseline, Week 4 and Week 12

  3. Percentage of Participants Continuously Treated With 6 Milligram Per Day Regimen Until Week 12 - Intent-to-treat (ITT) Population

    Percentage of participants who were continuously treated with paliperidone extended-release (ER) 6 milligram per day regimen until Week 12 are reported here.

    Measured: Week 12

  4. Percentage of Participants Continuously Treated With 6 Milligram Per Day Regimen Until Week 12 - Per Protocol (PP) Population

    Percentage of participants who were continuously treated with paliperidone extended-release (ER) 6 milligram per day regimen until week 12 are reported here.

    Measured: Week 12

  5. Drug Attitude Inventory (DAI) Score - Intent-to-treat (ITT) Population

    The DAI-10 is a 10-item questionnaire to assess 1) subjective experience of drug and 2) attitudes and beliefs toward neuroleptics which may influence compliance in schizophrenia participants. It is the binary scale assessing the participant's subjective response. A 'compliant' response is scored as +1; a dysphoric response is scored as -1. A positive sum of items indicates a positive subjective response (SR); a negative sum of scores indicates a negative SR (non-compliant). The final score is the grand total of the positive and negative points. Total score ranges from (-) 10 to (+) 10, higher score indicates positive SR (compliant) and lower score indicates negative SR (non-compliant).

    Measured: Baseline, Week 4 and 12

  6. Drug Attitude Inventory (DAI) Score - Per Protocol (PP) Population

    The DAI-10 is a 10-item questionnaire to assess 1) subjective experience of drug and 2) attitudes and beliefs toward neuroleptics which may influence compliance in schizophrenia participants. It is the binary scale assessing the participant's subjective response. A 'compliant' response is scored as +1; a dysphoric response is scored as -1. A positive sum of items indicates a positive subjective response (SR); a negative sum of scores indicates a negative SR (non-compliant). The final score is the grand total of the positive and negative points. Total score ranges from (-) 10 to (+) 10, higher score indicates positive SR (compliant) and lower score indicates negative SR (non-compliant).

    Measured: Baseline, Week 4 and 12

  7. Clinical Global Impression - Severity (CGI-S) Score - Intent-to-treat (ITT) Population

    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.

    Measured: Baseline, Week 2, 4, 8 and 12

  8. Clinical Global Impression - Severity (CGI-S) Score - Per Protocol (PP) Population

    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.

    Measured: Baseline, Week 2, 4, 8 and 12

  9. Number of Participants With Categorical Scores Based on Clinical Global Impression - Improvement (CGI-I) Scale - Intent-to-treat (ITT) Population

    The CGI-I is a 7-point scale that requires the clinician to assess how much the participant's illness has improved or worsened relative to a baseline state at the beginning of the intervention and rated as: 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse.

    Measured: Week 12

  10. Number of Participants With Categorical Scores Based on Clinical Global Impression - Improvement (CGI-I) Scale - Per Protocol (PP) Population

    The CGI-I is a 7-point scale that requires the clinician to assess how much the participant's illness has improved or worsened relative to a baseline state at the beginning of the intervention and rated as: 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse.

    Measured: Week 12
