          -  Antisocial or Borderline Personality Disorder or other current DSM-IV-TR Axis II

             ineffective attempts) or who has ever been homicidal.

          -  Subject has no contact with an adult on a daily basis (i.e., subjects who are not
             living with at least one other adult or subjects who do not have an adult who contacts
             them on a daily basis). This criterion only applies to sites in Canadian sites and
             others where this is a local requirementa.

          -  Subject has a positive urine test at screening for illegal drug use and/or history of

             the Screening Visit. If a subject has a positive blood alcohol or positive illegal
             drug results, the subject is provisionally excluded and the test cannot be repeated
             without prior approval of the GSK medical monitor. NOTE: Subjects must be told to
             avoid consumption of alcoholic beverages for at least eight hours prior to the
             Screening Visit. The use of alcohol by subjects participating in the study is not
             recommended.

             is or will be exposed to an investigational or non-investigational drug or device; or
             (b) has participated in a clinical study for an illness unrelated to
             depression/anxiety within the preceding month; or (c) has participated in a clinical
             study related to depression/anxiety within the preceding six months.

          -  Subject has clinical evidence of, or ECG results indicating any of the following at
             either screen or Randomization Visit unless repeat ECG shows that the parameter had
             returned to within normal range by the Randomisation Visit. (The ECG may be repeated
             to see if the parameter returns to within range):

               -  QTc > 450 msec;

               -  any cardiac condition or ECG evidence that the investigator feels may predispose
                  the subject to ischemia or arrhythmia; or

               -  any ECG abnormality that, in the investigator's judgment, may pose a potential
                  safety concern.
