This is a study of a new medication for the treatment of cognitive impairments (thinking difficulties) and negative symptoms in people with schizophrenia. The new medication is rasagiline. Rasagiline is a drug which has been approved by the Food and Drug Administration for the treatment of Parkinson's disease. It is used to treat cognitive problems.

Primary Outcome Measures:
  • Scale for the Assessment of Negative Symptoms (SANS) [ Time Frame: Every 4 weeks over a 12 week period ]
    Scores on the subscales are combined (summed) to compute a total score. There are a total of 17 subscales. Each subscale ranges from 0="Not at all" to 5="Severe". Every 4 weeks the summed subscale scores provide a total score for that week (0-85). These total scores from each week are then combined (summed) for an overall score and then averaged for the two groups after the 12 week period.

Secondary Outcome Measures:
  • Neuropsychological Tests, Including RBANS, Probabilistic Learning Task, and N-Back Task [ Time Frame: Beginning of treatment phase (week 0) and end of treatment phase (week 12) ]
  • Simpson Angus Scale [ Time Frame: Every 4 weeks ]
  • Side Effect Checklist and Vital Signs [ Time Frame: Weekly ]

Enrollment: 84
Study Start Date: January 2007
Study Completion Date: February 2012
Primary Completion Date: February 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Rasagiline
Treatment with Rasagiline
Drug: rasagiline (Pharmacodynamics)
Rasagiline 1 mg/day for 12 weeks
Placebo Comparator: Inactive pill
Treatment with Placebo
Drug: Placebo
Placebo 1 tablet each day

Detailed Description:
The study will consist of two phases: a 4-week continued stability phase (lead-in phase) and a 12-week double-blind treatment phase. In the lead-in phase, subjects receiving antipsychotic medication, who manifest moderate to severe and persistent negative symptoms, will remain on their maintenance regimen for at least four weeks. The treatment phase will be a 12-week, parallel groups, double-blind, placebo-controlled trial of adjunctive rasagiline (1 mg/day), a selective MAO-B oxidase inhibitor.
