Objective: This study explores relevant outcomes with flexibly dosed paliperidone extended-release (ER) in a real-world design. Research design and methods: Patients were recruited from 23 countries. Adults with non-acute schizophrenia (n = 1812), previously unsuccessfully treated with other oral antipsychotics, were transitioned to paliperidone ER and prospectively treated for 6 months. Main outcome measures: Primary efficacy outcome for patients switching for the main reason of lack of efficacy was ≥ 20% improvement in Positive and Negative Syndrome Scale (PANSS) total scores. For patients switching for main reasons other than lack of efficacy, primary outcome was non-inferiority in efficacy compared with the previous medication. Results: Among the lack-of-efficacy group, 61% achieved a ≥ 20% improvement in PANSS total scores from baseline to endpoint. For switchers from other than the lack-of-efficacy group, efficacy maintenance after switching to paliperidone ER was confirmed. Clinically relevant and statistically significant symptomatic improvements occurred for each patient group based on main reason for switching. Conclusion: Paliperidone ER was well tolerated and associated with a meaningful clinical response in patients who switched from other oral antipsychotics, with insomnia and anxiety as most frequent side-effects.
