Detailed 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

Ages Eligible for Study:   20 Years to 55 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

  • Is taking any antidepressant that is excluded, including tricyclic antidepressants and monoamine oxidase inhibitors, at any time from 8 weeks prior to the Day -1 Visit.
  • Has significant suicidal ideation at Initial Screening Visit.
  • Has had a suicide attempt within 1 year prior to the Day -1 Visit.
  • Has participated in another trial utilizing the MATRICS Consensus Cognitive Battery (MCCB) or UCSD Performance-Based Skills Assessment (UPSA) (any version) within 6 months prior to Initial Screening Visit.
  • Is currently enrolled in any form of cognitive remediation training.
