NCT ID: NCT00589914

Last Updated: 2014-06-24

Results Overview

The PANSS scale is used to assess the neuropsychiatric symptoms of schizophrenia. The 30-item PANSS scale provides a total score (sum of the scores of all 30 items) and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items),and the general psychopathology subscale (16 items), each item rated on a scale of 1 (absent) to 7 (extreme).

Participant Flow

This is a 13 week double-blind study to assess safety and efficacy of flexible dose of Paliperidone Palmitate (50, 100 or 150 mg equivalent) in patients aged 18 years or older with schizophrenia.

In this study 1221 patients were enrolled of which 1220 patients were randomized as 1 patient was enrolled twice. Only the first patient number was included in the all randomized patients, safety, and intent to treat analysis sets. Out of 1220 patients 1214 patients received at least 1 dose of study medication.

PRIMARY outcome

Timeframe: Baseline to the last postrandomization assessment in the double-blind treatment period (approximately 13 weeks)

Population: The per-protocol analysis set of patients included those randomized to treatment after IEC/ IRB approval of protocol Amendment INT-4 with both a baseline measurement and at least 1 postrandomization measurement on the primary efficacy variable, a minimum exposure of 36 days to the double-blind treatment regimen, and no major protocol violations.

The PANSS scale is used to assess the neuropsychiatric symptoms of schizophrenia. The 30-item PANSS scale provides a total score (sum of the scores of all 30 items) and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items),and the general psychopathology subscale (16 items), each item rated on a scale of 1 (absent) to 7 (extreme).

SECONDARY outcome

Timeframe: Baseline to the last postrandomization assessment in the double-blind treatment period (approximately 13 weeks)]

Population: The intent-to-treat (ITT) analysis set of patients included those randomized to treatment after IEC/IRB approval of protocol Amendment INT-4 who received at least 1 injection of double-blind study drug and had at least 1 efficacy measurement during the double-blind treatment period.

The CGI-S rating scale is used to rate the severity of a patient's psychotic condition on a 7-point scale ranging from 1 (not ill) to 7 (extremely severe). This scale permits a global evaluation of the patient's condition at a given time. A qualified rater administered the CGI-S.

Timeframe: Baseline to the last postrandomization assessment in the double-blind treatment period (approximately 13 weeks)

Population: The intent-to-treat (ITT) analysis set of patients included those randomized to treatment after IEC/IRB approval of protocol Amendment INT-4 who received at least 1 injection of double-blind study drug and had at least 1 efficacy measurement during the double-blind treatment period.

The PSP scale is used to assess the degree of dysfunction a patient exhibits over a 7-day period within 4 domains of behavior: socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behavior. The results of the assessment are converted to a numeric score. A score between 71 and 100 indicates a mild degree of difficulty; a score between 31 and 70 indicates a moderate degree of dysfunction, and a patient with a score of 30 or less has functioning so poor he or she requires intensive supervision.
