- Least Square Mean Change From Randomization to Week 8 in Hamilton Rating Scale for Anxiety (HAM-A) Total Score [ Time Frame: Baseline (randomization) and then 8 weeks ]
Hamilton Rating Scale for Anxiety (HAM-A) consists of 14 items to evaluate anxiety. Each item is rated on a scale from 0-4, with '0' showing no anxiety (not present) and '4' showing the worst (very severe).
Results based on MITT population with available data for this outcome measure. Least square mean of each treatment was adjusted for baseline value.
- Least Square Mean Change From Randomization to Week 8 in Clinical Global Impression-Severity of Illness (CGI-S) Score [ Time Frame: Baseline (randomization) and then 8 weeks ]
The CGI-S is assessed on a seven-point scale ranging from most extremely ill/very much worse (7) to normal/very much improved (1).
Results based on MITT population with available data for this outcome measure.
- Number of Patients With Clinical Global Impression-Global Improvement (CGI-I) Score of "Much/Very Much Improved" at Week 8 [ Time Frame: Baseline (randomization) and then 8 weeks ]
This pertains to the CGI-I scale which rates improvement of anxiety on a scale from 1-7, with '1' showing the best improvement(Very Much Improved) and '7' showing the worst improvement (Very Much Worse) as compared to the baseline visit. A rating of '2' indicates 'Much Improved'.
Results based on MITT population with available data for this outcome measure.
- Least Square Mean Change From Randomization to Week 8 in HAM-A Psychic Anxiety Subscale Score [ Time Frame: Baseline (randomization) and then 8 weeks ]The HAM-A psychic anxiety factor subscale is defined as the sum of the following 7 HAM-A factors: anxious mood, tension, fears, insomnia, intellectual, depressed mood and behavior at the interview (i.e.items 1-6 and 14, respectively) Results based on MITT population with available data for this outcome measure.
- Least Square Mean Change From Randomization to Week 8 in HAM-A Somatic Anxiety Subscale Score [ Time Frame: Baseline (randomization) and then 8 weeks ]
The HAM-A Somatic cluster subscale is defined as the sum of the following 7 HAM-A items: somatic (muscular), somatic (sensory), cardiovascular symptoms, respiratory symptoms, gastrointestinal symptoms, genitourinary symptoms and autonomic system (i.e. items 7-13 respectively).
Results based on MITT population with available data for this outcome measure.
- Number of Patients With HAM-A Response (≥50% Score Reduction From Randomization) at Week 8 [ Time Frame: Baseline (randomization) and then 8 weeks ]Hamilton Rating Scale for Anxiety (HAM-A) response is derived from the HAM-A total score and is defined as a decrease from baseline total HAM-A score of at least 50%. (1=Yes, 0=No) Results based on MITT population with available data for this outcome measure.
- Number of Patients With HAM-A Remission (Total Score ≤7) at Week 8 [ Time Frame: Baseline (randomization) and then 8 weeks ]Hamilton Rating Scale for Anxiety (HAM-A) remission is derived from the HAM-A total score and is defined as a HAM-A total score of ≤7. 1=Yes, 0=No Results based on MITT population with available data for this outcome measure.
- Least Square Mean Change From Randomization to Week 8 in Quality of Life Enjoyment and Satisfaction Questionaire (Q-LES-Q) Percent Maximum Total Score [ Time Frame: Baseline (randomization) and then 8 weeks ]
The Q-LES-Q score is the sum of the first 14 items, larger values indicating a higher perceived quality of life enjoyment and satisfaction. This total score was converted to a % maximum score using the following scoring conversion: %Maximum score = (Total score-14)*(100/560)rounded to an integer.
Results based on MITT population with available data for this outcome measure.
- Mean Change From Randomization to Week 8 in Q-LES-Q Item 15 (Satisfaction With Medication) Score [ Time Frame: Baseline (randomization) and then 8 weeks ]Results based on MITT population with available data for this outcome measure.
- Mean Change From Randomization to Week 8 in Q-LES-Q Item 16 (Overall Quality of Life) Score [ Time Frame: Baseline (randomization) and then 8 weeks ]Results based on MITT population with available data for this outcome measure.
- Least Square Mean Change From Randomization to Week 1 in HAM-A Total Score [ Time Frame: Baseline (randomization) and then 8 weeks ]
Hamilton Rating Scale for Anxiety (HAM-A) consists of 14 items to evaluate anxiety. Each item is rated on a scale from 0-4, with '0' showing no anxiety (not present) and '4' showing the worst (very severe).
Results based on MITT population with available data for this outcome measure.
