Salsalate as an Adjunctive Treatment for Patients With Schizophrenia

5. april 2018 opdateret af: Xiaoduo Fan, University of Massachusetts, Worcester

This is a 12-week, open-label trial of salsalate 3 g/day as an adjunctive treatment in 15 schizophrenia subjects to examine salsalate's effect on psychopathology, cognitive functioning, and metabolic parameters.

Potential subjects will be identified by their clinicians at the Freedom Trail Clinic, or Massachusetts General Hospital. A total of 15 subjects will be enrolled.

Detaljeret beskrivelse

The specific aims include:

Primary aims:

  1. Examine the efficacy of salsalate (3g/day) in improving positive and negative symptoms as measured by the Positive and Negative Syndrome Scale (PANSS) and the Scale for Assessment of Negative Symptoms (SANS).
  2. Examine the efficacy of salsalate in improving cognition as measured by the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) composite score.

Secondary aims:

1. Examine salsalate's effects on inflammatory markers such as high sensitivity C-reactive protein (hs-CRP), TNF-α and IL-6.

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
PANSS Total Score
Tidsramme: Baseline and 12 weeks
Positive and negative symptoms of schizophrenia will be measured by total score on all subscales of the Positive and Negative Syndrome Scale (PANSS; score range 30-210). Higher scores correspond with worse outcomes.
Baseline and 12 weeks
SANS Total Score
Tidsramme: Baseline, 12 weeks
Negative symptoms of schizophrenia will be measured by total score on the Scale for Assessment of Negative Symptoms (SANS; score range 0-100). Higher scores correspond with worse outcomes.
Baseline, 12 weeks
MATRICS Composite Score
Tidsramme: Baseline, 12 weeks
Improved cognition will be measured using the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) assessment. The MATRICS assessment includes a battery of tests, and the composite t-score measures cognition across 7 domains including speed of processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving, and social cognition. A higher score indicates better cognition.
Baseline, 12 weeks
PANSS Positive Score
Tidsramme: Baseline, 12 weeks
Subscale of Positive and Negative Syndrome Scale that specifically measures positive symptoms. The scores range from 7-49, with higher scores representing a worse outcome.
Baseline, 12 weeks
PANSS- Negative Score
Tidsramme: Baseline, 12 weeks
Subscale of Positive and Negative Syndrome Scale that specifically measures negative symptoms. The scores range from 7-49, with higher scores representing a worse outcome.
Baseline, 12 weeks

Foranstaltningsbeskrivelse
Tidsramme
Hs-CRP
Tidsramme: Baseline, 12 weeks
High-sensitivity C-reactive protein (hs-CRP) will be measured in mg/L in order to detect inflammation. Higher hs-CRP values correspond to higher levels of inflammation.
Baseline, 12 weeks
TNF-alpha
Tidsramme: Baseline,12 weeks
Tumor necrosis-alpha factor will be measured to assess inflammation levels.
Baseline,12 weeks
IL-6
Tidsramme: Baseline, week 12
IL-6 (interleukin 6) is a marker used to measure inflammation.
Baseline, week 12
