Major Depressive Disorder
Brief summary
The primary purpose of this study is to compare the long-term efficacy and safety of desvenlafaxine succinate sustained release versus placebo in adults with Major Depressive Disorder, using a randomized withdrawal design. Randomized withdrawal means that after receiving desvenlafaxine succinate sustained release for a predetermined period of time, subjects will be selected by chance to either continue receiving the study drug or to be withdrawn from the study drug and receive placebo for the remainder of their participation in the trial. Subjects will not know to which group they have been assigned. The study consists of an up to 14-day screening period followed by an 8-week open-label period in which subjects will knowingly receive 50 mg/day of desvenlafaxine succinate sustained release. Subjects who do not respond to treatment, demonstrating no significant change in their depressive symptoms, will be withdrawn from participation at the end of this period. Responding subjects will receive an additional 3 months of open-label desvenlafaxine succinate sustained release at the same dose. Subjects with stable response to treatment at the conclusion of this 3 month period will be randomized to either desvenlafaxine succinate sustained release at 50 mg/day or placebo in a blinded manner for an additional 6 months or until symptoms of depression return. Following discontinuation at any point after enrollment in the study, subjects will receive two weeks of follow-up monitoring, including one week of blinded taper with 25 mg/day of desvenlafaxine succinate sustained release treatment for any subjects who have been taking desvenlafaxine succinate sustained release prior to discontinuation. Subjects assigned to placebo will receive a blinded placebo taper. Following taper, subjects will be evaluated for one additional week to monitor safety.
Interventions
50 mg tablet, once daily. 5 months open-label duration for all enrolled subjects; additional 6 months double-blind duration for randomized subjects assigned to this arm.
25 mg tablet for taper, once daily for 1 week
Matching placebo tablet, once daily. 6 months double-blind duration for randomized subjects assigned to placebo.

|---|---|---|
| Change From Baseline in Clinical Global Impression-Severity of Illness [CGI-S] Score in the Double-blind Phase | Double-blind phase Baseline (Study Day 140) up to Week 26 (Study Day 322) | CGI-S is a 7-point clinician rated scale to assess severity of participant's current illness state; range of 1 (normal - not ill at all) to 7 (among the most extremely ill). Higher score = more affected. Change from baseline mean=adjusted mean change calculated using mixed-effects model for repeated measures (MMRM). |
| Change From Baseline in Hamilton Psychiatric Scale for Depression-17 Item (HAM-D17) Score in the Double-blind Phase | Double-blind phase Baseline (Study Day 140) up to Week 26 (Study Day 322) | HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression (symptoms such as depressed mood, guilty feelings, suicide, sleep disturbances, anxiety levels, and weight loss). Nine items are scored on a 3 point scale (0=none/absent to 2=most severe) and 8 items are scored on a 5 point scale (0=none/absent to 4=most severe) for a maximum total score of 50; higher score indicates more depression. Change from baseline mean=adjusted mean change calculated using MMRM. |

Improvement defined as a score of 1 (very much improved), 2 (much improved), or 3 (minimally improved) on the scale. |
| Change From Baseline of Double-blind Phase in World Health Organization (Five-Item) Well-Being Index | Double-blind phase Baseline (Study Day 140), Week 14 (Study Day 238), Week 26 (Study Day 322) | WHO-5 evaluates positive psychological well-being during the past 2 weeks and consists of 5 questions (felt cheerful, in good spirits; felt calm, relaxed; felt active, vigorous; woke up fresh, rested; and daily life filled with things that are interesting) each rated on a 6-point Likert scale from 0 (not present) to 5 (constantly present). Total raw score ranged from 0 (worst possible quality of life) to 25 (best possible quality of life). Change from baseline mean=adjusted mean change calculated using MMRM. |
| Change From Baseline in Work Productivity and Activity Impairment Questionnaire (WPAI) Score in the Double-blind Phase | Double-blind phase Baseline (Study Day 140), Week 14 (Study Day 238), Week 26 (Study Day 322) | WPAI is a 6 question participant rated questionnaire to determine the degree to which depression affected work productivity while at work and affected activities outside of work. Four scores are derived: percentage of absenteeism, percentage of presenteeism (reduced productivity while at work), an overall work impairment score that combined absenteeism and presenteeism and percentage of impairment in activities performed outside of work. Scores scaled as 0 (not affected/no impairment) to 10 (completely affected/impaired). Higher score indicated greater impairment and less productivity. |

Change From Baseline in Work Productivity and Activity Impairment Questionnaire (WPAI) Score in the Double-blind Phase
WPAI is a 6 question participant rated questionnaire to determine the degree to which depression affected work productivity while at work and affected activities outside of work. Four scores are derived: percentage of absenteeism, percentage of presenteeism (reduced productivity while at work), an overall work impairment score that combined absenteeism and presenteeism and percentage of impairment in activities performed outside of work. Scores scaled as 0 (not affected/no impairment) to 10 (completely affected/impaired). Higher score indicated greater impairment and less productivity.
Time frame: Double-blind phase Baseline (Study Day 140), Week 14 (Study Day 238), Week 26 (Study Day 322)
Population: All Randomized population. Change from baseline (Bsl) mean=adjusted mean change calculated using MMRM.

Number of Participants With Remission Based on Hamilton Psychiatric Scale for Depression-17 Item (HAM-D17) Score at Double-blind Phase Week 26
HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression (symptoms such as depressed mood, guilty feelings, suicide, sleep disturbances, anxiety levels, and weight loss). Nine items are scored on a 3 point scale (0=none/absent to 2=most severe) and 8 items are scored on a 5 point scale (0=none/absent to 4=most severe) for a maximum total score of 50; higher score indicates more depression. Remission defined as HAM-D17 total score ≤7.
Time frame: Double-blind phase Week 26 (Study Day 322)
Population: All Randomized population. N=number of participants with analyzable data at observation based on Last Observation Carried Forward (LOCF).
