A Study to Compare Disease Progression and Modification Following Treatment With Paliperidone Palmitate Long-Acting Injection or Oral Antipsychotics in Participant's With Recent-onset Schizophrenia or Schizophreniform

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.
