| Sumario: | Huafang Li,1,2 Yan Li,1,2 Yu Feng,3 Jianmin Zhuo,4 Ibrahim Turkoz,5 Maju Mathews,5 Wilson Tan3 1Shanghai Mental Health Centre, Shanghai Jiao Tong University School of Medicine, Shanghai, China; 2Shanghai Key Laboratory of Psychotic Disorders, Shanghai, China; 3Janssen Pharmaceutical Companies of Johnson and Johnson, Singapore; 4Janssen China Research and Development, Shanghai, China; 5Janssen Research & Development LLC, Titusville, NJ, USA Purpose: To evaluate the differences in efficacy and safety outcomes in acute exacerbating schizophrenia patients between 2 subgroups (≤1 week and >1 week), differing in time interval from hospitalization to time of initiation of once-monthly paliperidone palmitate. Patients and methods: PREVAIL was a multicenter, single-arm, open-label, prospective Phase IV study in hospitalized Asian patients (either sex, aged 18–65 years) diagnosed with schizophrenia (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition). Change from baseline to week 13 in primary (Positive and Negative Syndrome Scale [PANSS] total score), secondary endpoints (PANSS responder rate, PANSS subscale, PANSS Marder factor, Clinical Global Impression-Severity, and Personal and Social Performance scale scores, readiness for hospital discharge questionnaire) and safety were assessed in this post hoc analysis. Results: Significant mean reduction from baseline to week 13 in the PANSS total score, 30% PANSS responder rates (P≤0.01), PANSS subscales (positive and general psychopathology; all P≤0.01), PANSS Marder factor (positive symptoms, uncontrolled hostility, and excitement and anxiety/depression; all P≤0.01), Personal and Social Performance scale scores (P≤0.05) and Clinical Global Impression-Severity categorical summary (P≤0.05) were significantly greater in the ≤1 week subgroup versus >1 week subgroup (P≤0.05). The readiness for hospital discharge questionnaire improved over time for the overall study population, but remained similar between subgroups at all-time points. Treatment-emergent adverse events were similar between the subgroups. Conclusion: Early initiation of once-monthly paliperidone palmitate in hospitalized patients with acute exacerbation of schizophrenia led to greater improvements in psychotic symptoms with comparable safety than treatment initiation following 1 week of hospitalization.
