Primary outcomes

  1. Change in Baseline in the Hamilton Rating Scale for Anxiety (HAM-A) Total Score

    Time frame: Baseline to Week 8

    The Hamilton Anxiety Rating Scale (HAM-A) is a clinician-administered scale which consists of 14 items, each rated on a five point scale ranging from 0 (not present) to 4 (very severe). The highest possible score is 56, which represents the most severe form of anxiety; the lowest possible score is 0, which represents an absence of anxiety.

Secondary outcomes

  1. Change From Baseline in the Sheehan Disability Scale (SDS) Total Score

    Time frame: Baseline to Week 8

    The Sheehan Disability Scale (SDS) is a 3-item clinician-rated questionnaire used to evaluate impairments in the domains of work, social life/leisure, and family life/home responsibility. All items are rated on an 11-point continuum (0 = no impairment to 10 = most severe) with the total SDS score ranging from 0 (no impairment) to 30 (most severe).
