Brief Summary:
This six-arm study is being conducted to measure the effect of a combination of paroxetine and vestipitant on the arousal induced by public speaking in Seasonal Effective Disorder (SAD) patients, using functional brain imaging readouts (i.e., WAT(Wave Analysis Technology) PET(Positron Emission Tomography)), after one or eight weeks of treatment. The effect of paroxetine alone after one or eight weeks of treatment will also be measured.

Condition or disease Intervention/treatment Phase
Depressive Disorder and Anxiety Disorders Drug: vestipitant Drug: paroxetine Phase 2

Detailed Description:
A double-blind, double dummy, placebo-controlled, randomised, parallel group positron emission tomography study to investigate the effects of a 8 week administration of vestipitant and paroxetine in combination or paroxetine alone on regional cerebral blood flow during a public speaking test in subjects affected by social anxiety disorder.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 72 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Double-blind, Triple Dummy, Placebo-controlled, Randomised, Parallel Group Positron Emission Tomography Study to Investigate the Effects of a 8 Week Administration of GW597599 and Paroxetine Either Alone or in Combination on Regional Cerebral Blood Flow During a Public Speaking Test in Subjects Affected by Social Phobia.

Intervention Details:
    Drug: vestipitant Drug: paroxetine
    Other Name: vestipitant


Primary Outcome Measures :
  1. To assess, by mean of Positron Emission Tomography, the degree of regional Cerebral Blood Flow in different brain regions involved in the emotional brain circuit during public speaking task before treatment and after eight weeks of treatment.

Secondary Outcome Measures :
  1. To assess symptomatic and physiological measures of anxiety induced by the public speaking task and social anxiety symptoms during eight weeks of treatment. To evaluate safety, tolerability and the effect on sexual function of treatment.
