A Study to Investigate the Effects of GW876008 on Brain Activation During Emotional Processing in Healthy Subjects.
13 ottobre 2010 aggiornato da: 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

- Read, comprehend, and write English at a sufficient level to complete study-related materials.
- Provide a signed and dated written informed consent prior to study participation
Exclusion Criteria:

- Any history of suicidal attempts or behaviour.
- Any history or current diagnosis of a psychiatric illness.
- Any history of an endocrine disorder including, but not limited to, diabetes or disorders of the hypothalamus, pituitary, adrenal, or thyroid glands, or gonadal disorder or dysfunction of the reproductive organs.
