Trial Outcomes & Findings for Safety and Efficacy of Cariprazine in Schizophrenia (NCT NCT01104779)

NCT ID: NCT01104779

Last Updated: 2018-11-14

Results Overview

The Positive and Negative Syndrome Scale is a 30-item rating scale specifically developed to asses both the positive and negative symptom syndromes of patients with schizophrenia. The PANSS total score is rated based on a structured clinical interview with the patient and supporting clinical information obtained from family, hospital staff, or other reliable informants. This assessment provides scores in 9 clinical domains, including a positive syndrome, a negative syndrome, depression, a composite index, and general psychopathology. Each item is scored on a 7-point (1 to 7) scale, with 1 being minimal impact, and 7 being highest impact. The cumulative score ranges from 30 to 210. A negative change score indicates improvement.

PRIMARY outcome

Timeframe: Baseline to Week 6

Population: Intent-to-Treat Population, consisting of all patients in the Safety Population who had at least one postbaseline assessment of the PANSS total score.

The Positive and Negative Syndrome Scale is a 30-item rating scale specifically developed to asses both the positive and negative symptom syndromes of patients with schizophrenia. The PANSS total score is rated based on a structured clinical interview with the patient and supporting clinical information obtained from family, hospital staff, or other reliable informants.

SECONDARY outcome

Timeframe: Baseline to Week 6

Population: Intent-to-Treat Population, consisting of all patients in the Safety Population who had at least one postbaseline assessment of the PANSS total score.

The Clinical Global Impressions-Severity scale is a clinician-rated scale that measures the overall severity of a participant's illness in comparison with the severity of illness in other participants the physician has observed. The participant is rated on a scale from 1 to 7 with 1 indicating a "normal state" and 7 indicating "among the most extremely ill participants." A higher score indicates greater illness. A negative change score indicates improvement.
