Switching to paliperidone extended release in patients with schizophrenia dissatisfied with previous olanzapine treatment: Post hoc analysis of an open-label, prospective study.

ABSTRACT: OBJECTIVE:This post hoc analysis of an open-label, single-arm, multicenter study was designed to assess the efficacy, safety, and tolerability of paliperidone extended release (ER) in Chinese patients with non-acute schizophrenia, after switching from olanzapine. METHODS:Patients with schizophrenia who were dissatisfied with prior olanzapine treatment switched to flexible paliperidone ER (3-12?mg/day) based on clinical judgment. Change from baseline to week 12 in Positive and Negative Syndrome Scale (PANSS) total scores (primary endpoint), PANSS subscale scores, response rate, Clinical Global Impression-Severity (CGI-S) score, personal and social performance (PSP) scores, patient satisfaction with treatment score, change in sleep quality, level of daytime sleepiness and safety were evaluated. RESULTS:Out of 118 enrolled patients, 95 (81%) completed the study. Mean duration of study was 76.9 (23.85) days. The primary endpoint, mean (SD) PANSS total score changed significantly from baseline to endpoint (-19.6 [18.71], P?<.0001). Secondary endpoints including PANSS subscale score, PSP, patient satisfaction and daytime drowsiness also significantly improved (P?<.001). Most commonly reported (?1%) treatment-emergent adverse events were akathisia (n?=?14 [12%]) and insomnia (n?=?9 [8%]). CONCLUSIONS:Switching to flexible-dosed paliperidone ER in patients dissatisfied with prior olanzapine treatment achieved good efficacy and tolerability consistently over 12 weeks.
