Clinical Trial Summary

This is an efficacy and safety study evaluating an experimental treatment for cognitive deficits in adults with schizophrenia.

Description:

This is a Phase 2 study designed to evaluate the efficacy and safety of ABT-288 in approximately 210 adults with schizophrenia. Subjects will be randomized to one of three treatment groups (ABT-288 Dose 1, ABT-288 Dose 2 or placebo) for a 12-week Treatment Period. The purpose of this research study is to find out whether ABT-288 compared to placebo can improve cognition and what side effects ABT 288 may cause. Cognition is the way a person thinks, and it includes abilities like paying attention, focusing, remembering things, and solving problems. Acronyms listed in the Outcomes and/or Eligibility sections for this study are defined below:

• MCCB: Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery

• UPSA-2: University of California at San Diego (UCSD) Performance-Based Skills Assessment-2

• CANTAB: Cambridge Neuropsychological Test Automated Battery

• PANSS: Positive and Negative Syndrome Scale

• NSA-16: Negative Symptom Assessment-16

• CGI-S: Clinical Global Impression - Severity

Recruitment information / eligibility

• Status: Completed
• Enrollment: 214
• Est. completion date: July 2011
• Est. primary completion date: July 2011
• Accepts healthy volunteers: No
• Gender: All
• Age group: 20 Years to 55 Years
