Overview
Brief Summary
The purpose of the study is to compare effectiveness of paliperidone palmitate (PP: paliperidone palmitate once-monthly and 3-month injections) versus oral antipsychotic (OAP [that is oral paliperidone extended release {ER}, oral risperidone, or another OAP]) in delaying time to treatment failure. The study will also evaluate changes in cognition, functioning, brain intracortical myelin (ICM) volume following treatment with PP compared with OAP in participants with recent-onset schizophrenia or schizophreniform disorder.
Detailed Description
A Prospective, matched-control, Randomized (assignment of study drug by chance), open-label, flexible-dose, study in participants with recent-onset schizophrenia or schizophreniform disorder to compare disease progression and disease modification following treatment with PP long-acting injection (once-monthly followed by 3-month injections) or OAP (Any of the following 7 OAPs are permitted: aripiprazole, haloperidol, olanzapine, paliperidone ER, perphenazine, quetiapine, and risperidone). The study consists of 3 parts. Part-1 (Oral Run-In Phase), Part-2 (Disease Progression) and Part-3 (Extended Disease Progression and Disease Modification) with unique endpoints. Screening period will be up to 4 Weeks. Duration of Parts will be as: 2 months for Part-1, 9 months for Part-2 and Part-3. All participants will initially receive oral paliperidone ER or oral risperidone in Part-1. After paliperidone/risperidone treatment in Part-1, participants will be randomized into 1:2 ratio to receive PP or OAP in Part-2. Participants who complete Part-2 will enter into Part-3 wherein OAP group participants of Part-2 will be re-randomized into 1:1 ratio to OAP-OAP group and OAP-PP group, and PP group will continue without further randomization. Treatment failures will be evaluated in Part-2 and Part-3 of the study. Also changes in cognition, functioning, brain intracortical myelin (ICM) volume will be evaluated in the study. Participants' safety will be monitored throughout. Healthy controls (comparable in age, sex, race, and highest parental education to the treated participants) were recruited at each of the 3 MRI centers as controls for the MRI machine calibration for the duration of the study. These healthy controls were to undergo MRI assessments, but were not otherwise involved with the study and did not receive study medication. No safety or efficacy data were collected for these healthy controls.

Outcomes
Primary Outcomes
Part 3 (Extended Disease Progression [EDP]): Change From Baseline in Cognition as Measured by the MATRICS Consensus Cognitive Battery (MCCB) Composite Score
Time Frame: Baseline and 18 Months
The MATRICS Consensus Cognitive Battery is an instrument that contains 10 tests to measure cognitive performance in 7 cognitive domains: speed processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving, and social cognition. The composite score combines the individual scores of the 10 tests and scores them on a normative scale to derive a T-score and composites scores. The range of T-scores for a normal control population is between 0 to 100 with a mean of 50 and standard deviation of 10. Higher scores indicate better cognitive functioning.
Part-2 (Disease Progression): Time to First Treatment Failure
Time Frame: From Day 1 up to 9 Months
Treatment failure is defined as the time from participant's randomization to first treatment failure, which was a composite endpoint consisting of any of the following: 1) Psychiatric hospitalization due to worsening symptoms; 2) Any deliberate self-injury, suicidal ideation or behavior, homicidal ideation or violent behavior that is clinically significant and needs immediate intervention as determined by the study physician; 3) New arrest/incarceration; 4) Discontinuation of antipsychotic treatment due to inadequate efficacy as determined by the study physician; 5) Discontinuation of antipsychotic treatment due to safety or tolerability as determined by the study physician; 6) Treatment supplementation with another antipsychotic due to inadequate efficacy as determined by the study physician; 7) Increase in the level of psychiatric services in order to prevent imminent psychiatric hospitalization as determined by the study physician.
Part 3 (Disease Modification): Change From Baseline in Cognition as Measured by the MATRICS Consensus Cognitive Battery (MCCB) Composite Score
Time Frame: Baseline and Day 260
The MATRICS Consensus Cognitive Battery is an instrument that contains 10 tests to measure cognitive performance in 7 cognitive domains: speed processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving, and social cognition. The composite score combines the individual scores of the 10 tests and scores them on a normative scale to derive a T-score and composites scores. The range of T-scores for a normal control population is between 0 to 100 with a mean of 50 and standard deviation of 10. Higher scores indicate better cognitive functioning.
