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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 55 years (ADULT)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame
Cognition: MCCB

Outcome Measure
Time Frame
Functioning: UPSA-2

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
