  Purpose
This study will assess the safety, tolerability and efficacy of desvenlafaxine succinate sustained release (DVS SR) in subjects with major depressive disorder.

Condition Intervention Phase
Depressive Disorder, Major Drug: DVS SR Drug: Paroxetine Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized

Primary Purpose: Treatment
Official Title: A Multicenter, Randomized, Double-blind, Paroxetine-referenced, Parallel-group Study to Evaluate the Safety, Efficacy, and Tolerability of 3 Fixed Doses (50mg, 100mg, AND 200mg) of Desvenlafaxine Succinate Sustained-release Tablets in Adult Outpatients With Major Depressive Disorder

Primary Outcome Measures:
  • Percentage of Responders With a 50% or Greater Decrease From Baseline on the Hamilton Rating Scale for Depression, 17-item (HAM-D17) [ Time Frame: 8 weeks ]
    HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on either a 3 point (0 to 2) or a 5 point scale (0 to 4), with 0=none/absent and 4=most severe, for a maximum total score of 50.


Secondary Outcome Measures:
  • Clinical Global Impressions Scale-Improvement (CGI-I) Scores [ Time Frame: 8 weeks ]
    CGI-I is a global rating scale that measures disease improvement. Using a 7-point scale, the clinician rates how much the subject's illness has improved or worsened relative to the baseline status (1= very much improved; 7= very much worse).

  • Clinical Global Impressions Scale-Severity of Illness (CGI-S) Scores [ Time Frame: 8 weeks ]
    CGI-S is a global rating scale that measures the severity of a subject's disease. Using a 7-point scale, the clinician rates the severity of the patient's mental illness at the time of the assessment, relative to the clinician's experience with subjects who have the same diagnosis (1= normal, not at all ill; 7= among the most extremely ill).

  • Montgomery and Asberg Depression Rating Scale (MADRS) Total Score Mean Change From Baseline [ Time Frame: Baseline and 8 weeks ]
    Measures the overall severity of depressive symptoms. The MADRS has a 10-item checklist. Items are rated on a scale of 0-6, for a total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms).

  • Visual Analog Scale-pain Intensity (VAS-PI) Score Mean Change From Baseline [ Time Frame: 8 weeks ]
    The VAS-PI is a self-rated visual analog scale for the assessment of pain. Scores on the VAS-PI range from 0 (no pain) to 10 (worst possible pain). A decrease in VAS-PI overall scores indicates a subject's assessment of an improvement in pain.

  • Hamilton Rating Scale for Depression, 6-item (HAM-D6) Score Mean Change From Baseline [ Time Frame: 8 weeks ]
    HAM-D6: standardized, clinician-administered rating scale is a subset of the HAM-D17 that assesses 6 items associated with major depression. The scale uses HAM-D17 items 1, 2, 7, 8, 10 and 13. Item 13 is scored 0 to 2 (0=none/absent to 2=most severe) and all others are scored 0 to 4 (0=none/absent to 4=most severe). Total score ranges from 0 to 22; higher score indicates more depression.

  • Covi Anxiety Scale Score Mean Change From Baseline [ Time Frame: 8 weeks ]
    Covi anxiety scale measures the severity of anxiety symptoms on 3 items: verbal report, behavior and somatic complaints. Each dimension is assessed using a 5-point scale: 1 = not at all, 2 = somewhat, 3 = moderately, 4 = considerably, 5 = Very much. Total score ranges from 3 to 15; higher score indicates more anxiety.

Detailed Description:
The primary objective of this study is to investigate the efficacy, safety and tolerability of desvenlafaxine succinate sustained release (DVS SR) in Chinese, Taiwanese, South Korean, and Indian subjects with major depressive disorder (MDD) receiving daily doses of 50 mg, 100 mg, or 200 mg. The secondary objective is to obtain additional information regarding the efficacy of DVS SR in subjects with MDD receiving daily doses of 50 mg, 100 mg, or 200 mg. Additional objectives include obtaining general and functional quality of life outcome data.
