Trial Outcomes & Findings for A Trial to Explore the Tolerability, Safety and Efficacy of Paliperidone Extended Release in Patients With Schizophrenia (NCT NCT01606228)

NCT ID: NCT01606228

Last Updated: 2012-10-22

Results Overview

The PANSS is a 30-item scale (range 30-210) designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and poor impulse control. The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score consists of the sum of all 30 PANSS items. Higher scores indicate worsening.

Participant Flow

There were 188 patients enrolled in the study which were included in the safety analysis set. The main analysis set included only 176 subjects due to 12 protocol violations. Of these 176 patients, only 73 were included in the per-protocol analysis set. For the Clinical Global Impression-Severity scores, data was collected for only 60 patients.

Timeframe: Baseline

Population: Per Protocol (PP) population

This PSP assesses the degree of a patient's dysfunction within 4 domains of behavior: socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behavior. The score ranges from 1 to 100, divided into 10 equal intervals to rate the degree of difficulty (i, absent to vi, very severe) in each of the 4 domains. Based on the four domains there will be one total score. Patients with a score of 71 to 100 have a mild degree of difficulty; from 31 to 70, varying degrees of disability; =\< 30, functioning so poorly as to require intensive supervision.
