Brief Title  ICMJE 12-Week Study of Pristiq (Desvenlafaxine) Social Anxiety Disorder
Official Title  ICMJE A 12-Week Double-Blind, Placebo-Controlled, Flexible-Dose Trial of Pristiq® (Desvenlafaxine) Extended-Release Tablets in Generalized Social Anxiety Disorder
Brief Summary This study is designed to evaluate the efficacy and safety of Pristiq® in treatment of the symptoms of Generalized Social Anxiety Disorder (SAD).
Detailed Description Social Anxiety Disorder (SAD) is recognized as a prevalent, chronic and disabling condition. Lifetime prevalence has been estimated at 13% in the National Comorbidity Survey. There is good reason to think that Pristiq® would be effective in Social Anxiety Disorder. Effexor XR, which is mechanistically similar to Pristiq®, was found effective for subjects with Generalized Social Anxiety Disorder in all five of the placebo controlled trials in which it was studied.
