Inclusion Criteria:

  • Men or women age > 65 years.
  • A primary diagnosis of Generalized Anxiety Disorder according to the Diagnostic and Statistical Manual-IV (DSM-IV).
  • Subjects must have a HAM-A score of 16 or higher at both screening and baseline visits.

Exclusion Criteria:

  • Women who are pregnant or contemplating pregnancy (eg, via in vitro fertilization) during the study through 30 days after the last dose of study medication.
  • Subjects with evidence of a current (within the past 6 months) clinically significant or unstable hematological, autoimmune, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, pancreatic, psychiatric, neurologic, immunological or retinal disorder; subjects with an active infection within the past 2 months.

Outcomes

Primary Outcome Measures

Discontinuations due to adverse events or adverse events occurring during and after the discontinuation of trial medication
The nature, incidence, duration, and severity of adverse events.
Suicide related adverse events will be further assessed using the Columbia Suicide Severity Rating Scale as needed
The primary outcome is safety which will be assessed throughout the 6-months by physical exams, monitoring of vital signs, body weight changes, and clinical safety laboratory
Electrocardiograms will be performed to assess any changes in cardiac functioning related to the compound

Secondary Outcome Measures

Symptom severity of generalized Anxiety Disorder (GAD) will be measured by the Hamilton Rating Scale for Anxiety (HAM-A).
Overall Health Care utilization will be assessed with the Health Care Utilization (HCU) questionnaire.
Also, the Daily Diary (including the Daily assessment of Symptoms DAS-A and Global Anxiety - Visual Analog Scale (GA-VAS) and the Clinical Global Impression of Severity (CGI-S) will be used to assess symptoms of GAD.
Plasma concentrations will be collected to evaluate the population pharmacokinetics and the dose/exposure relationships for safety and efficacy .
