The HAM-A is an anxiety rating scale consisting of 14 items that assess anxious mood, tension, fear, insomnia, intellectual (cognitive) symptoms, depressed mood, behavior at interview, somatic (sensory), cardiovascular, respiratory, gastrointestinal, genitourinary, autonomic and somatic (muscular) symptoms. Each symptom is rated from 0 (absent) to 4 (maximum severity). Total scores range from 0 to 56 where <17 indicates mild severity, 18-24 mild to moderate severity and 25-30 moderate to severe. Total scores above 30 are rare, but indicate very severe anxiety. Least Squares (LS) means were from a mixed model for repeated measurements (MMRM) with Baseline-by-week, center, week and week-by-treatment as factors in the analysis.

The Full Analysis Set included all patients who were randomized, received at least 1 dose of study drug, and had at least 1 post-baseline value for assessment of primary efficacy. A mixed model for repeated measurements (MMRM) based on observed cases was used.

The Hospital Anxiety and Depression (HAD) Anxiety sub-scale consists of 7 items that are assessed on a scale from 0 (no anxiety) to 3 (severe feeling of anxiety). The anxiety subscale determines a state of generalized anxiety including anxious mood, restlessness, anxious thoughts and panic attacks. Scores are summed and range from 0 to 21 (maximal severity). LS means were from a MMRM with Baseline-by-week, center, week and week-by-treatment as factors in the analysis.

The Sheehan Disability Scale assesses functional impairment in 3 domains: work/school, social life or leisure activities, and home life or family responsibilities. The participant rates the extent to which each aspect is impaired on a 10-point visual analog scale, from 0 (not at all) to 10 (extremely). The 3 scores are added together to calculate the total score, which ranges from 0 to 30, with higher scores indicating more impairment. LS means were from a MMRM with Baseline-by-week, center, week and week-by-treatment as factors in the analysis.
