Clinical Trial Summary

The purpose of this study is to evaluate the efficacy, tolerability and safety of paliperidone extended release (ER) tablets (between 3 to 12 milligram (mg), once a day) in the prevention of relapse in schizophrenia participants.

Description:

This is a double-blind (neither physician nor participant knows the name of the assigned drug), randomized (participants are assigned to treatment by a chance), placebo-controlled, and parallel-group study of paliperidone ER tablets. The study will consist of 6 phases: 14 days of screening phase, 8 weeks of open-label run-in phase (participants will be flexibly dosed with paliperidone ER once daily in a dose range of 3 mg to 12 mg), 6 weeks of stabilization phase (participants will continue to receive the fixed dose of paliperidone ER), double-blind (DB) phase of various length (participants will be randomly assigned in a 1:1 ratio to receive either paliperidone ER or placebo and this phase will be completed after 86 relapse events are observed or if the study is positive at the interim analysis), 6 months of open-label extension (participants who experience a relapse event or who remain relapse free for the entire duration of the double-blind phase and participants who are enrolled at the time the study is terminated, will be eligible for this phase. All participants will be treated with paliperidone ER and safety and tolerability information will be collected during this phase) phase and 6 months of follow-up phase (participants who withdraw during the DB phase for any reason other than relapse will be followed for 6 months or until they experience a relapse). Participants' safety will be monitored throughout the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Double Blind (DB) Phase: Median Time to Relapse	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.	DB Baseline (Day 1 of Week 15) up to interim analysis data cut-off (24 August 2012) (Approximately 1 year)	No
Secondary	Run-In and Stabilization Phase: Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 14	The PANSS is a 30-item scale designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and 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 the sum of all 30 PANSS items and ranges from 30 to 210. Higher scores indicate worsening.	Baseline and Week 14	No
Secondary	Double Blind (DB) Phase: Change From DB Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at DB Endpoint	The PANSS is a 30-item scale designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and 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 the sum of all 30 PANSS items and ranges from 30 to 210. Higher scores indicate worsening. Change at DB endpoint was calculated as value at interim analysis data cut-off (09 November 2012) minus value at DB Baseline (Day 1 of week 15).
