- Differences in brain activation elicited by Matching Emotional Face Expression paradigm following single oral doses of GW876008 and lorazepam on day 1, sessions 1-4
- GW876008 blood levels [ Time Frame: pre-dose & post-dose, sessions 1-4 ]
- clinical rating scales change after dosing: questionnaires collected [ Time Frame: pre-dose & up to 6-8 hours post-dose. ]
- Safety: 12-lead ECG, vital signs, adverse events, clinical labs
- fMRI BOLD neuroanatomical structure of the emotional brain neurocircuitry and connectivity
- fMRI BOLD Signal characteristics and connectivity
- fMRI BOLD Response in the emotional brain neurocircuitry and occipital cortex.
- ETCo2 in mm Hg, to be recorded for the duration of the scan session and be synchronized with the single fMRI procedure timing
- Visual Analog Scale (VAS) measurements of sleepiness, alertness, calm, tension, and anxiety performed before dosing (baseline), pre-fMRI session, post-fMRI session and just before leaving the facility.
- Association between the anxiety trait (STAI-trait, test battery for neuroticism or liability for Anxiety Disorders) collected at screening and the various pharmacodynamic parameters measured in the various testing conditions.
- GW876008 concentration to determine pharmacokinetic parameters to be collected twice per session,
- Pharmacogenetic (PGx) assessments
- Safety and tolerability of GW876008 to include Vital signs semi-supine; respiratory rate, pulse oximetry and ECG.
- Clinical laboratory tests
- fMRI BOLD ALS signal.
- Heart rate (HR; beats per minute), to be recorded for the whole duration of the scan session and to be synchronized with the single fMRI procedure timing.
- Respiratory rate (RR: inspiration per minute), to be recorded for the duration of scan session and be synchronized with the single fMRI procedure timing. .
