Trial Outcomes & Findings for Symptomatic Remission and Social Function in Participants Treated With Paliperidone Extended Release (ER) (NCT NCT01577186)

NCT ID: NCT01577186

Last Updated: 2014-01-17

Results Overview

The PANSS is a 30-item scale to assess the neuropsychiatric symptoms of schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self). The PANSS provides a total score and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each item scored on a scale of 1 (absent), 2 (minimal), 3 (mild), 4 (moderate), 5 (moderately severe), 6 (severe) and 7 (extreme). The total score ranges from 30 to 210 and higher score indicates greater severity. Symptomatic remission was defined as achieving intensity level of mild or moderate on PANSS scale by all 8 items as the determinants for symptomatic remission: delusions, unusual thought content, hallucinatory behavior, conceptual disorganization, mannerisms/posturing, blunted affect, social withdrawal, lack of spontaneity.

PRIMARY outcome

Timeframe: End of study (Up to Week 12)

Population: ITT population included all participants who received at least 1 dose of study drug and had at least one post-baseline assessment.

The PSP is 100-point validated clinician-rated scale that assesses degree of difficulty in 4 areas of functioning: socially useful activities, personal and social relationships, self-care, disturbing and aggressive behaviors rated on 6-point scale (1=absent to 6=very severe).Total transformed score from 1 to 100 is generated from raw score based on clinical interpretation of scores generated in 4 areas of functioning, with higher transformed score indicating better function. Total score is divided into 3 levels: 71-100 (mild difficulty); 31-70 (marked difficulty) and 1-30 (severe difficulty). Percentage of participants achieving improvement in PSP score by at least one category was reported.

SECONDARY outcome

Timeframe: End of study (Up to Week 12)

Population: ITT population included all participants who received at least 1 dose of study drug and had at least one post-baseline assessment. Here 'N' (Number of Participants Analyzed) signifies those participants who were evaluable for this measure.

The SFS is a 36-item scale designed to assess social functioning in schizophrenia. It assesses abilities and performance in seven areas: social engagement, interpersonal communication, activities of daily living, recreation, social activities, competence at independent living, and occupation/employment. Total score ranges from 1 to 100 where higher score indicates a more favorable health state.
