Primäre Ergebnismessungen

Maßnahmenbeschreibung
Zeitfenster
Change From Baseline in the Hamilton Anxiety Scale (HAM-A) Total Score
Zeitfenster: Baseline and Week 8
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 an analysis of covariance (ANCOVA) model with treatment and center as fixed factors and the Baseline value as a covariate.

Change From Baseline in Hamilton Anxiety Scale (HAM-A) Total Score at Other Weeks Assessed
Zeitfenster: Baseline and Weeks 1, 2, 4 and 6
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.

Baseline and Weeks 1, 2, 4 and 6
Percentage of Responders in HAM-A Total Score at Week 8
Zeitfenster: Baseline and Week 8
Response was defined as a participant with a ≥50% decrease from Baseline in the HAM-A total score. 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 (symptoms absent) to 56 (maximum severity).
Baseline and Week 8
Percentage of Participants in HAM-A Remission at Week 8
Zeitfenster: Week 8
Remission is defined as a Hamilton Anxiety Scale (HAM-A) total score ≤ 7. 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 (symptoms absent) to 56 (maximum severity).
Week 8
Clinical Global Impression Scale-Global Improvement (CGI-I) at Each Week Assessed
Zeitfenster: Baseline and Weeks 1, 2, 4, 6 and 8.
The Clinical Global Impression - Global Improvement scale assesses the participant's improvement (or worsening) as assessed by the clinician relative to Baseline on a 7-point scale: 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse. LS means were from an ANCOVA model adjusting for Baseline CGI-S score, center, and treatment.
Baseline and Weeks 1, 2, 4, 6 and 8.
Change From Baseline in Clinical Global Impression Scale-Severity of Illness (CGI-S)
Zeitfenster: Baseline and Weeks 1, 2, 4, 6 and 8.
The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the participant's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Considering total clinical experience, a patient is assessed on severity of mental illness on the following scale: 1, normal, not at all ill; 2, borderline mentally ill; 3, mildly ill; 4, moderately ill; 5, markedly ill; 6, severely ill; or 7, extremely ill. LS means were from an ANCOVA model adjusting for Baseline score, center, and treatment.
Baseline and Weeks 1, 2, 4, 6 and 8.
Change From Baseline in Hospital Anxiety and Depression (HAD) Scales
Zeitfenster: Baseline and Weeks 1, 4 and 8.
The HAD scale is completed by the participant and comprises two subscales, one measuring depression (focusing on the state of lost interest and diminished pleasure response) and one measuring anxiety (including anxious mood, restlessness, anxious thoughts, panic attacks). Each subscale is made up of 7 items that are assessed on a scale of 0 = no anxiety/depression to 3 = severe feeling of anxiety/depression. Participants are required to indicate the response which most accurately reflects the way they have felt over the last few days. Scores for the depression and anxiety subscales are summed separately and not combined, with each score ranging from 0 to 21 (maximal severity). LS means were from an ANCOVA model with treatment and center as fixed factors and the Baseline value as a covariate.
Baseline and Weeks 1, 4 and 8.
Change From Baseline in Sheehan Disability Scale (SDS) at Week 8
Zeitfenster: Baseline and Week 8
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 an ANCOVA model with treatment and center as fixed factors and the Baseline value as a covariate.
Baseline and Week 8
Change From Baseline in 36-item Short-form Health Survey (SF-36)
Zeitfenster: Baseline and Week 8
The Medical Outcomes Study SF-36 is a participant self-rated questionnaire that is a general measure of perceived health status comprising 36 questions, which yields an 8-scale health profile. The 8 health concepts are: 1. Limitation in physical activities because of health problems. 2. Limitations in usual role activities because of physical health problems. 3. Bodily pain. 4. Limitations in social activities because of physical or emotional problems. 5. General mental health (psychological distress and well-being). 6. Limitations in usual role activities because of emotional problems. 7. Vitality (energy and fatigue). 8. General health perception. Each scale ranges from 0 (best) - 100 (worst). LS means were from an ANCOVA model with treatment and center as fixed factors and the baseline value as a covariate.
Baseline and Week 8
Health Care Resource Utilization Assessed by the Health Economic Assessment Questionnaire
Zeitfenster: Baseline and Week 8
Healthcare resource utilization was assessed by the Health Economic Assessment (HEA) questionnaire, which monitors participants absenteeism from work, as well as resource use such as visits to a general practitioner, outpatient and inpatient services, hospitalization, medications, and other relevant services over the past 8 weeks.
