Safety and Efficacy Study for Cognitive Deficits in Adult Subjects With Schizophrenia

June 1, 2018 updated by: AbbVie (prior sponsor, Abbott)

A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Phase 2 Study of the Safety and Efficacy of ABT-126 in the Treatment of Cognitive Deficits in Schizophrenia (CDS)

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

Detailed Description

This is a Phase 2 study designed to evaluate the efficacy and safety of ABT-126 in approximately 210 adults with schizophrenia. Subjects will be randomized to one of three treatment groups (ABT-126 Dose 1, ABT-126 Dose 2 or placebo) for a 12-week Treatment Period. The purpose of this research study is to find out whether ABT-126 compared to placebo can improve cognition and what side effects ABT-126 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
