|Study Start Date :||August 2007|
|Actual Primary Completion Date :||July 2011|
|Actual Study Completion Date :||March 2012|
Experimental: escitalopram + bupropion
escitalopram plus bupropion extra long (XL) as dual treatment (i.e., this is not a SINGLE treatment arm; all patients assigned this arm received both medications)
Drug: escitalopram + bupropion
same dosing schedule as for monotherapy
Active Comparator: escitalopram
10mg/d increasing by 10 mg/week to a maximum of 40 mg/d if tolerated and not remitted
Other Name: Lexapro
Active Comparator: bupropion
bupropion extra long (XL) monotherapy
Drug: bupropion extra long (XL)
150mg/d increasing to 300 mg/d after 1 week and 450 mg/d after 3 weeks, all increases if tolerated and not remitted
Other Name: Wellbutrin extra long (XL)
- Time to Remission, Defined by the Week of Onset of Persistent Hamilton Rating Scale for Depression (HAM-D 17) <= 7, With no Subsequent HAM-D 17 > 7 [ Time Frame: 12 weeks ]Life Table Survival Analysis run twice, once comparing Dual Therapy (i.e., Bupropion + Escitalopram) to Bupropion alone (i.e., Bupropion + Placebo) and once comparing Dual Therapy to Escitalopram alone (i.e., Escitalopram + Placebo). Because both analyses must significantly favor Dual Therapy, each individual analysis must reach a critical alpha = .0916 in order to reach an over-all alpha = .05.
- Remission: Persistent Hamilton Rating Scale for Depression, 17 Items (HAM-D 17) <= 7, With no HAM-D 17 >7 Through Week 12 [ Time Frame: 12 weeks ]Chi square comparison of rates of persistent remission (i.e., no subsequent Hamilton Rating Scale for Depression, 17 items [HAMD-D 17] > 7 once HAMD-D 17 <= 7); Dual rate vs. Escitalopram only rate and Dual rate vs. Bupropion only rate.
- Severity of Depressive Symptoms as Measured by Hamilton Rating Scale for Depression (HAM-D 17) [ Time Frame: 12 weeks ]
Last summary score rating on the 17-item Hamilton Rating Scale for Depression Eight items are scored on a 5-point scale, ranging from 0 = not present to 4 = severe. Nine are scored from 0-2. Range 0-58.
0-7 = Normal 8-13 = Mild Depression 14-18 = Moderate Depression 19-22 = Severe Depression
≥ 23 = Very Severe Depression
- Functioning, as Measured by the Social Adjustment Scale (SAS) Summary Score [ Time Frame: 12 weeks ]Social adjustment was measured using the Social Adjustment Scale (SAS). The SAS is a self-report scale that assesses depressive symptoms and functioning in nine social and work-related domains generating a total score that is indicative of a subject's overall level of social adjustment. Subjects rate their own social functioning over times on a 5-point scale on items covering work for pay, housework, extended family, parenting, marital status, social activity and leisure, family unit and student status (sub-scales). Mean values of all the sub-scales are used, with a range from 0-5. Higher score = worse outcome … worse functioning
- Quality of Life, as Measured by the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) Short Form (SF) [ Time Frame: 12 weeks ]
The Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) intends to measure quality of life in 16 domains. A summary score is computed by adding the scores and dividing by 16 (or the number of answered items if some are not answered).
The minimum raw score on the Q-LES-Q-SF is 14, and the maximum score is 70. Higher score means more satisfaction.
