Double-blind Treatment Period: Change From Baseline in Hamilton Anxiety Rating Subscale (HAM-A6) Score at Week 6 (eITT Population)
The HAM-A6 is a 6-item subscale derived from the original Hamilton Anxiety scale (HAM-A) which consists of 5 psychic anxiety symptoms (anxious mood, psychic tension, fears, intellectual disturbances, and anxious behavior observed at the interview), as well as one somatic item (muscular tension). Each of the 6 items is rated by the clinician on a 5-point scale ranging from 0 (not present) to 4 (maximum degree). The HAM-A6 score was calculated by summing the 6 item scores, and ranges from 0 to 24. Higher scores indicated greater severity of symptoms.

Double-blind Treatment Period: Change From Baseline in Hamilton Depression Rating Subscale (HAM-D6) Score at Week 6 (eITT Population)
HAM-D6 is a 6-item subscale derived from HDRS17 and consists of depressed mood, guilt feelings, work and interests, psychomotor retardation, psychic anxiety, and somatics symptoms (tiredness and pain), rated on a 5-point scale, where 0 = not present, and 1-4 represent increasingly severe symptoms. Each of these items is rated by the clinician on either a 3-point (0 to 2) or a 5-point scale (0 to 4). The point scale used a rating of 0 (absent), 1 (doubtful to mild), 2 (mild to moderate), 3 (moderate to severe), and 4 (very severe). General somatic is scored 0 to 2 and all others are scored 0 to 4. The HAM-D6 is calculated from summing the 6 items and the score ranges from 0 (normal) to 22 (severe), with higher scores indicating greater severity of core symptoms.

Double-blind Treatment Period: Change From Baseline in Structured Interview Guide of the Hamilton Anxiety Scale (SIGH-A) Total Score at Week 6 (eITT Population)
The SIGH-A was included as a means to determine the frequency and severity of signs and symptoms of anxiety; and determine both their influence on treatment and their responsiveness to treatment. The SIGH-A scale consists of 14 items with a score of 0 to 4, where 0=absent, 1=mild, 2=moderate, 3=severe, 4=incapacitating.
