Trial Outcomes & Findings for An Efficacy and Safety Study of Risperidone Long-Acting Microspheres in Participants With Schizophrenia, Schizophreniform or Schizoaffective Disorders (NCT NCT01855074)

NCT ID: NCT01855074

Last Updated: 2013-08-14

Results Overview

The PANSS is a 30-item scale 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 and ranges from 30 to 210, higher scores indicate worsening. Change at Week 26 score is calculated as Baseline score minus Week 26 score.

The CGI rating scale is a 7-point global assessment that measures the clinician's impression of the severity of illness exhibited by a participant. A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill participants", higher scores indicate worsening.

The SF-36 is a standardized survey evaluating 8 aspects of functional health and well being: vitality, physical function, social function, physical role, emotional role, bodily pain, general health, mental health. Each item is scored on a scale ranging from 0-100 (100=highest level of functioning).

The GAF is a 100-point tool to measure overall psychological, social and occupational functioning of adults. The higher score range (91 to 100) refers to a superior functioning in a wide range of activities, and absence of symptoms. The lower score range (1 to 10) refers to persistent danger of severely hurting self or others; or persistent inability to maintain minimum personal hygiene; or serious suicidal act with clear expectation of death.

An ESRS scale is used to assess the extrapyramidal symptoms attributable to antipsychotics. It consists of 8 items to assess individual symptoms and each item is assessed from 0 (none, absent) to 4 (severe). The total score is the sum of the 8 item scores, for a total range of 0 (normal) to 32 severe). The items for the assessment of individual symptoms are classified into 4 categories of parkinsonism, akathisia, dystonia and dyskinesia.
