What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from Baseline to Week 4 in Montgomery Asberg Depression Rating Scale (MADRS) total score
Time Frame: Up to 4 weeks
|
The Montgomery Asberg Depression rating scale is a 10-item scale used to assess the severity of depression.
Individual items are scored on a 7-point scale (0 to 6).
The total score is the sum of individual items, ranging from 0 to 60; where a higher score indicates more depression.
|
Up to 4 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from Baseline to Weeks 1, 2, and 3 in Montgomery Asberg Depression Rating Scale total score
Time Frame: Up to 3 weeks
|
The Montgomery Asberg Depression rating scale is a 10-item scale used to assess the severity of depression.
Individual items are scored on a 7-point scale (0 to 6).
The total score is the sum of individual items, ranging from 0 to 60; where a higher score indicates more depression.
|
Up to 3 weeks
|
Change from Baseline to Weeks 1, 2, 3, and 4 in Clinical Global Impression - Severity (CGI-S) total score
Time Frame: Up to 4 weeks
|
The CGI-S is a 7-point scale to rate the severity of the participant's illness at the time of assessment, relative to the clinician's past experience with participants who have the same diagnosis.
A score of 1 represents "normal" and 7 represents "most extremely ill".
|
Up to 4 weeks
|
Change from Baseline to Week 5 and change from Week 4 to Week 5 in MADRS total score
Time Frame: Up to 5 weeks
|
The Montgomery Asberg Depression rating scale is a 10-item scale used to assess the severity of depression.
Individual items are scored on a 7-point scale (0 to 6).
The total score is the sum of individual items, ranging from 0 to 60; where a higher score indicates more depression.
|
Up to 5 weeks
|
Change from Baseline to Week 5 and change from Week 4 to Week 5 in CGI-S total score
Time Frame: Up to 5 weeks
|
The CGI-S is a 7-point scale to rate the severity of the participant's illness at the time of assessment, relative to the clinician's past experience with participants who have the same diagnosis.
A score of 1 represents "normal" and 7 represents "most extremely ill".
|
Up to 5 weeks
|
Change from Baseline to Week 2 and Week 4 in the 17-item Hamilton Depression Rating Scale (HAM D-17) total score
Time Frame: Up to 4 weeks
|
The 17-item Hamilton Depression rating scale is used to assess the severity of depression.
Individual items are scored on either a 3-point (0 to 2) or a 5-point scale (0 to 4), with 0=No difficulty/absent and 4=most severe.
The total score is the sum of individual items, ranging from 0 to 52; where a higher score indicates more depression.
|
Up to 4 weeks
|
Change from Baseline to Week 2 and Week 4 in the Sheehan Disability Scale (SDS)
Time Frame: Up to 4 weeks
|
The Sheehan Disability Scale is a 3-part scale that measures the degree of disruption on work, social and family life using an 11-point scale where 0 represents "no disruption" and 10 represents "extreme disruption".
In addition to the 11-point scale, participants are asked to indicate the number of days in the past week that were "lost" and numbers of days that were "unproductive".
The results of these questions have a range from 0 to 7. A total global functioning impairment score can be utilized by summing the scores from work, social and family life scales for a value range from 0 to 30.
|
Up to 4 weeks
|
Change from Baseline to Week 2 and Week 4 in the Quick Inventory of Depressive Symptomology - Self Report (QIDS-SR)
Time Frame: Up to 4 weeks
|
The Quick Inventory of Depressive Symptomology - Self Report (QIDS-SR), is a 16 item self-reported scale where each item has a 4-point scale where 0 represents least impact scores while 3 represents greatest impact scores.
Some questions are linked.
The total score ranges from 0 to 27 where a higher score indicates more depression.
|
Up to 4 weeks
|
Change from Baseline to Week 2 and Week 4 in the Quality of Life Enjoyment and Satisfaction Questionnaire - Short Form (Q-LES-Q-SF)
Time Frame: Up to 4 weeks
|
The Quality of Life Enjoyment and Satisfaction Questionnaire - Short Form (Q-LES-Q-SF) is a 16 item satisfaction scale where each item has a 5-point scale.
A score of 1 represents "very poor satisfaction", while a score of 5 represents "very good satisfaction".
Only the first 14 items are summed for a total score that ranges from 14 to 70.
