Study Details

Study Description

Brief Summary

Desvenlafaxine succinate (DVS) is a potent and selective serotonin and norepinephrine reuptake inhibitor (SNRI). The sustained-release (SR) formulation, DVS SR, is being studied in the development program for the treatment of major depressive disorder (MDD), for vasomotor symptoms (VMS) associated with menopause, and for pain associated with peripheral diabetic neuropathy, as well as for the treatment of fibromyalgia syndrome. This study will investigate the safety, efficacy, and tolerability of DVS SR in women with MDD who are peri- and postmenopausal.

Outcome Measures

Primary Outcome Measures

  1. Change in Hamilton Psychiatric Rating Scale for Depression (HAM-D17) Score From Baseline to Week 8. [Baseline to 8 weeks]

    HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on a 0 to 2-4 scale (0=none/absent and 4=most severe) with a maximum total score of 50. Change= 8 week adjusted mean HAM-D17 minus baseline adjusted mean HAM-D17

Secondary Outcome Measures

  1. Percentage of Patients With Each Clinical Global Impression Improvement (CGI-I) Score [8 weeks]

    CGI-I is a global rating scale that measures disease improvement. Using a 7-point scale, the clinician rates how much the patient's illness has improved or worsened relative to the baseline status (1= very much improved; 7= very much worse).

  2. Percentage of Patients Achieving Remission [8 weeks]

    Remission is defined as a Hamilton Psychiatric Rating Scale for Depression (HAM-D17) score of ≤ 7. HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on a 0 to 2-4 scale (0=none/absent and 4=most severe) with a maximum total score of 50.

  3. Percentage of Patients Achieving Response to Treatment [8 weeks]

    A response is defined as ≥ 50% decrease from baseline on Hamilton Psychiatric Rating Scale for Depression (HAM-D17) score. HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on a 0 to 2-4 scale (0=none/absent and 4=most severe) with a maximum total score of 50.

  4. Change in Hamilton Psychiatric Rating Scale for Anxiety (HAM-A) Score From Baseline to Week 8 [Baseline to 8 weeks]

    The HAM-A is a standardized, clinician-administered rating scale that assesses 14 items characteristically associated with major anxiety disorders. Items are scaled 0 - 4 (0=none and 4=very severe), with a maximum total score of 56. Change= 8 week adjusted mean HAM-A score minus baseline adjusted mean score.

  5. Change in Dimension Health State EuroQol (EQ-5D) Score From Baseline to Week 8 [Baseline to 8 weeks]

    EQ-5D is a standardized, subject-administered measure of health outcome. It provides a descriptive profile for 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), using 3 levels (no, moderate, or extreme problems) and a single index value characterizing current health status using a 100-point visual analog scale (0=worst, 100=best). EQ-5D summary index is obtained with a formula that weights each level of the dimensions. The index-based score is interpreted along a continuum of 0 (death) to 1 (perfect health). Change=8 week score minus baseline score.

  6. Change in Hamilton Psychiatric Rating Scale for Depression (HAM-D17) Score From Open Label Baseline to 6 Months [open label baseline and 6 months]

    HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on a 0 to 2-4 scale (0=none/absent and 4=most severe) with a maximum total s core of 50. Change= Final Evaluation mean HAM-D17 minus baseline mean HAM-D17.

  7. Clinical Global Impression Improvement (CGI-I) Score [6 months]

    CGI-I is a global rating scale that measures disease improvement. Using a 7-point scale the clinician rates how much the patient's illness has improved or worsened relative to the baseline status (1= very much improved; 7= very much worse)

  8. Percentage of Patients Achieving Remission [6 months]

    Remission is defined as a Hamilton Psychiatric Rating Scale for Depression (HAM-D17) score of ≤ 7. HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on a 0 to 2-4 scale (0=none/absent and 4=most severe) with a maximum total s core of 50.

  9. Percentage of Patients Achieving a Response to Treatment [6 months]

    A responder is defined as a patient with ≥ 50% decrease from baseline on Hamilton Psychiatric Rating Scale for Depression - 17-item (HAM-D17) score. HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on a 0 to 2-4 scale (0=none/absent and 4=most severe) with a maximum total score of 50.

  10. Change in Hamilton Psychiatric Rating Scale for Anxiety (HAM-A) Score From Open Label Baseline to 6 Months [open label baseline to 6 months]

    The HAM-A is a standardized, clinician-administered rating scale that assesses 14 items characteristically associated with major anxiety disorders. Items are scaled 0 - 4 (0=none and 4=very severe), with a maximum total score of 56. Change= Final Evaluation mean HAM-A score minus baseline mean score.

  11. Change in Dimension Health State EuroQol (EQ-5D) Score From Open Label Baseline to 6 Months [open label baseline to 6 months]

    EQ-5D is a standardized, subject-administered measure of health outcome. It provides a descriptive profile for 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), using 3 levels (no, moderate, or extreme problems) and a single index value characterizing current health status using a 100-point visual analog scale (0=worst, 100=best). EQ-5D summary index is obtained with a formula that weights each level of the dimensions. The index-based score is interpreted along a continuum of 0 (death) to 1 (perfect health). Change=8 week score minus baseline score.

  12. Discontinuation-Emergent Signs and Symptoms (DESS) Total Score [6 months]

    DESS: a clinician-administered 43-item assessment that evaluates discontinuation-emergent symptoms resulting from the withdrawal from test article. The DESS total score is the sum of the number of "new symptoms" and "old (but worse) symptoms" (1) and 0 for "old and unchanged symptom," "absent," or "old symptom but improved" for a total possible range of 0 to 43. A higher score indicates more symptoms.

6. Secondary Outcome
Title Change in Dimension Health State EuroQol (EQ-5D) Score From Baseline to Week 8
Description EQ-5D is a standardized, subject-administered measure of health outcome. It provides a descriptive profile for 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), using 3 levels (no, moderate, or extreme problems) and a single index value characterizing current health status using a 100-point visual analog scale (0=worst, 100=best). EQ-5D summary index is obtained with a formula that weights each level of the dimensions. The index-based score is interpreted along a continuum of 0 (death) to 1 (perfect health). Change=8 week score minus baseline score.
Time Frame Baseline to 8 weeks
