  Purpose

This study involves people with schizophrenia or schizoaffective disorder, who are currently taking antipsychotic medications. Some antipsychotic medications may cause an increase in cholesterol levels, which may lead to inflammation in the body. Inflammation poses a risk in developing heart disease, diabetes and problems with brain function. The purpose of this study is to see if pravastatin can:

  • Lower cholesterol
  • Decrease inflammation
  • Improve cognition in patients with schizophrenia

Condition Intervention Phase
Schizophrenia Schizoaffective Disorders Schizophreniform Disorders Drug: Pravastatin Drug: Placebo Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Phase 4 Study of the Effects of Pravastatin on Cholesterol Levels, Inflammation and Cognition in Schizophrenia

Primary Outcome Measures:
  • Change in LDL-cholesterol Between Baseline and Week 12 [ Time Frame: Baseline, week 12 ]
  • Change in C-Reactive Protein (CRP) From Baseline to Week 12 [ Time Frame: Baseline, week 12 ]
  • Change in MATRICS Neuropsychological Battery Composite Score From Baseline to Week 12 [ Time Frame: Baseline, week 12 ]

    The Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery measures cognitive functioning within 7 domains: speed of processing, attention/vigilance, working memory (non verbal and verbal), verbal learning, visual learning, reasoning and problem solving and social cognition.

    The composite score is calculated by the MATRICS computer program, which equally weights each of the 7 domain scores. The range of composite scores is 20-80. Higher scores indicate higher levels or cognitive functioning, while lower scores indicate lower levels of cognitive functioning.


  • Change in Positive and Negative Syndrome Scale (PANSS) Total Score From Baseline to Week 12 [ Time Frame: Baseline, week 12 ]
    The Positive and Negative Syndrome Scale (PANSS) is a scale used to rate severity of schizophrenia. All items are summed to calculate the total score. The scale range is 30-210. Better outcomes have lower numbers and worse outcomes have higher numbers.

  • Change in Positive and Negative Syndrome Scale (PANSS) Positive Score From Baseline to Week 12 [ Time Frame: Baseline, week 12 ]
    This is a subscale of the Positive and Negative Syndrome Scale (PANSS). The range for this subscale is 7-49. All items are summed to calculate the total score. Better outcomes have lower numbers and worse outcomes have higher numbers.

  • Change in Positive and Negative Syndrome Scale (PANSS) Negative Score From Baseline to Week 12 [ Time Frame: Baseline, week 12 ]
    This is a subscale of the Positive and Negative Syndrome Scale (PANSS). The range for this subscale is 7-49. All items are summed to calculate the total score. Better outcomes have lower numbers and worse outcomes have higher numbers.

  • Change in Positive and Negative Syndrome Scale (PANSS) General Score From Baseline to Week 12 [ Time Frame: Baseline, week 12 ]
    This is a subscale of the Positive and Negative Syndrome Scale (PANSS). The range for this subscale is 15-105. All items are summed to calculate the total score. Better outcomes have lower numbers and worse outcomes have higher numbers.


Enrollment: 60
Study Start Date: June 2010
Study Completion Date: September 2012
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: pravastatin
pravastatin 40mg, once a day, shortly after baseline for 12 consecutive weeks
Drug: Pravastatin
pravastatin 40mg, or placebo, once a day, shortly after baseline for 12 consecutive weeks
Other Names:
  • pravastatin sodium
  • Pravachol
Placebo Comparator: Placebo
placebo, once a day, shortly after baseline for 12 consecutive weeks
Drug: Placebo
pravastatin 40mg, or placebo, once a day, shortly after baseline for 12 consecutive weeks

Detailed Description:
This study is a 12-week randomized, double-blind, placebo-controlled pilot study of pravastatin 40mg a day, administered for 12 consecutive weeks to subjects with schizophrenia to examine pravastatin's effects on lowering cholesterol levels and inflammatory markers, and improving cognition. The study will be conducted at the Freedom Trail Clinic and will use the Massachusetts General Hospital Clinical Research Center. The innovative approach of using pravastatin to not only decrease cholesterol levels, but to decrease inflammation and improve cognition in patients with schizophrenia is promising and may lead to a different approach to treatment in this population.
