Trial Outcomes & Findings for A Study to Evaluate Effectiveness and Safety of ER OROS Paliperidone in Patients With Schizophrenia (NCT NCT00396565)

NCT ID: NCT00396565

Last Updated: 2014-04-29

Results Overview

PANSS is a medical scale that assesses various symptoms of schizophrenia. The symptoms are rated on a 7-point scale from 1 (absent) to 7 (extreme psychopathology). The total score is the sum of all 30 PANSS items, with a range of 30 (absent) to 210 (extreme ill).

PRIMARY outcome

Timeframe: Baseline and 6 weeks

Population: Full Analysis Set excludes subjects who didn't receive test drug or didn't have post-treatment efficacy data. The Olanzapine (OLZ) group was set as an active drug group to examine clinical position of paliperidone (PAL) ER, and the superiority or non-inferiority of PAL ER 6mg to OLZ 10mg wasn't verified. LOCF imputation method was applied.

PANSS is a medical scale that assesses various symptoms of schizophrenia. The symptoms are rated on a 7-point scale from 1 (absent) to 7 (extreme psychopathology). The total score is the sum of all 30 PANSS items, with a range of 30 (absent) to 210 (extreme ill).

LOCF imputation method was applied.

The PANSS Positive Subscale assesses seven positive-symptoms of schizophrenia. Positive symptoms refer to an excess or distortion of normal functions. The symptoms are rated on a 7-point scale, with a range of 7 (absent) to 49 (extreme psychopathology).

The PANSS Negative Subscale assesses seven negative-symptoms of schizophrenia. Negative symptoms represent a diminution or loss of normal functions. The symptoms are rated on a 7-point scale, with a range of 7 (absent) to 49 (extreme psychopathology).

Responders are subjects with 30% or more reduction from baseline in total PANSS score. PANSS is a medical scale that assesses various symptoms of schizophrenia. The symptoms are rated on a 7-point scale from 1 (absent) to 7 (extreme psychopathology). The total score is the sum of all 30 PANSS items, with a range of 30 (absent) to 210 (extreme ill).
