The purpose of this study is to demonstrate the effectiveness of paliperidone palmitate in patients with Schizophrenia.

Clinical Details

Official title: A Randomized, Double-Blind, Parallel-Group, Comparative Study of Flexible Doses of Paliperidone Palmitate and Flexible Doses of Risperidone Long-Acting Intramuscular Injection in Subjects With Schizophrenia

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Change in the Positive and Negative Syndrome Scale (PANSS) Total Score for Schizophrenia

Secondary outcome:

The Change From Baseline for the CGI-S Score

The Change From Baseline in the PSP Score

Detailed description: This is a randomized (patients assigned to treatment groups by chance), double-blind (patient and study staff will not know the treatment assignment) study of paliperidone palmitate compared with RISPERDAL CONSTA (Risperidone Long-Acting Intramuscular Injection) in adult patients with schizophrenia. The total duration of the study will be approximately 14 weeks. For those patients without source documentation of tolerability to oral (by mouth) risperidone or paliperidone Extended Release (ER) tablets, injectable RISPERDAL CONSTA or paliperidone palmitate, or those patients who were not currently taking another antipsychotic, a minimum of 4 days and a maximum of 6 days of oral paliperidone ER treatment at a dosage of 6 mg/day will be administered for tolerability testing before the first injection of double-blind (DB) study drug (paliperidone palmitate or RISPERDAL CONSTA). During the DB period, study drug will be administered to patients as an intramuscular (i. m.) injection. Paliperidone palmitate (PP) 150mg equivalent (eq) (and RISPERDAL CONSTA placebo) at Baseline (BL) (Day 1), 100mg eq at Visit (V) 4 (Day 8), 50 or 100mg eq at V7 (Day 36), and 50,100,or 150mg eq at V9 (Day 64) or RISPERDAL CONSTA (RC) 25mg at V4 and V6 (Day 22), 25 or 37. 5mg at V7, and 25, 37. 5, or 50mg at V9 will be given as i. m. injections. Patients in the RC group will also take risperidone tablets (1-6 mg/day) at BL for 28 days and be given an injection of PP placebo at BL, V1, V7, and V9.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.
