A Study to Investigate the Effects of GW876008 on Brain Activation During Emotional Processing in Healthy Subjects.

October 13, 2010 updated by: GlaxoSmithKline

A Randomized, Placebo-controlled, Double-dummy, Four-way Crossover Design Study to Investigate the Changes of fMRI BOLD Activation Induced by Emotional Activation Paradigms Following Single Doses of GW876008 and Lorazepam (Comparator) in Healthy Subjects.

Data suggests that imaging activity of the brain can measure the effects of anti-anxiety drugs. This study will investigate the effect of GW876008 on areas of the brain involved with thinking and emotion

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.

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.

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.
Outcome Measure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
