Trial Outcomes & Findings for An Efficacy Study of Paliperidone for the Prevention of Relapse in Participants With Schizophrenia (NCT NCT01662310)

NCT ID: NCT01662310

Last Updated: 2014-09-29

Results Overview

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.

Measure
Paliperidone: Run-in or Stabilization Phase
Paliperidone extended-release (ER) oral tablet was administered at a starting dose of 3 milligram (mg) once daily for 8 weeks. Dose was increased from 3 milligram per day (mg/day) after 5 days based on Investigator's discretion, up to maximum of 12 mg/day.
Paliperidone: Double Blind (DB) Phase
Participants who transitioned from run-in or stabilization phase received paliperidone at a starting dose of 3 mg up to 12 mg, fixed dose of paliperidone ER oral tablet once daily during DB phase of the study.
Placebo: DB Phase
Participants who transitioned from run-in or stabilization phase received matching placebo once daily during DB phase of the study.
Paliperidone DB/Paliperidone Open-label (OL) Extension Phase
Participants who transitioned from paliperidone treatment group in DB phase (that is participants who experienced a relapse event during the DB phase or who remained relapse free for the entire duration of the double-blind phase and participants, who were enrolled at the time the study was terminated), entered open label extension phase, wherein paliperidone ER oral tablet was administered once daily as 3 to 12 mg.
Placebo DB/Paliperidone OL Extension Phase
Participants who transitioned from placebo treatment group in DB phase (that is participants who experienced a relapse event during the DB phase or who remained relapse free for the entire duration of the double-blind phase and participants, who were enrolled at the time the study was terminated), entered open label extension phase, wherein paliperidone ER oral tablet was administered once daily as 3 to 12 mg.

PRIMARY outcome

Timeframe: DB Baseline (Day 1 of Week 15) up to interim analysis data cut-off (24 August 2012) (Approximately 1 year)

Population: The Intent-to-Treat DB analysis set included all the participants who were randomized into the DB phase and who received at least one dose of DB study medication up to interim analysis cut-off date (24-Aug-2012). "N" (number of participants analyzed) signifies the participants evaluable for this measure.

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.

SECONDARY outcome

Timeframe: Baseline and Week 14

Population: The Intent-to-Treat (RI/ST) analysis set included all the participants who received at least one dose of study medication in run-in phase or stabilization phase. "n" signifies those participants who were evaluated for this measure at the specified time point. Last observation carried forward (LOCF) method was used to impute missing values.

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.

The PSP is 100-point validated clinician-rated scale that assesses degree of difficulty in 4 areas of functioning: socially useful activities, personal and social relationships, self-care, disturbing and aggressive behaviors rated on 6-point scale (1=absent to 6=very severe).Total transformed score from 1 to 100 is generated from raw score based on clinical interpretation of scores generated in 4 areas of functioning, with higher transformed score indicating better function. Total score is divided into 3 levels: 71-100 (mild difficulty); 31-70 (marked difficulty) and 1-30 (severe difficulty). Percentage of participants achieving improvement in PSP score by at least one category was reported.

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 final analysis at the end of double-blind treatment (09 November 2012).

Timeframe: OLE Baseline (09 November 2012) up to OLE endpoint (that is, up to 24 Weeks [26 April 2013] from DB endpoint)

Population: The Intent-to-Treat (ITT) OLE analysis set included all participants who received at least one dose of OLE medication as recorded on the electronic case report form (eCRF). LOCF method was used to impute missing values. "N" (number of participants analyzed) signifies the participants evaluable for this measure.

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 OLE endpoint was calculated as value at OLE endpoint (24 weeks after DB phase (26 April 2013) minus value at OLE Baseline (09 November 2012).

The PSP is 100-point validated clinician-rated scale that assesses degree of difficulty in 4 areas of functioning: socially useful activities, personal and social relationships, self-care, disturbing and aggressive behaviors rated on 6-point scale (1=absent to 6=very severe).Total transformed score from 1 to 100 is generated from raw score based on clinical interpretation of scores generated in 4 areas of functioning, with higher transformed score indicating better function. Total score is divided into 3 levels: 71-100 (mild difficulty); 31-70 (marked difficulty) and 1-30 (severe difficulty). Percentage of participants achieving improvement in PSP score by at least one category was reported. Change at OLE endpoint was calculated as value at OLE endpoint (24 weeks after DB phase (26 April 2013) minus value at OLE Baseline (09 November 2012).
