Study Evaluating Desvenlafaxine Succinate Sustained Release (DVS SR) in the Treatment of Major Depressive Disorder

June 8, 2011 updated by: Pfizer

A Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate the Efficacy and Safety of 2 Fixed Doses (25 and 50 mg/Day) of DVS SR Tablets in Adult Outpatients With Major Depressive Disorder

The primary purpose of this study is to compare the antidepressant efficacy and safety of two doses of DVS SR (25 and 50 mg/day) in the treatment of adults with Major Depressive Disorder. The study will also assess changes in sexual function and general and functional quality of life outcomes.

Baseline and Week 8 (or ET)
Change From Baseline in HAM-D6 Total Score at FOT Evaluation (Week 8 or ET)
Time Frame: Baseline and Week 8 (or ET)
HAM-D6: a standardized, clinician-administered rating scale that assesses 6 items characteristically associated with major depression and is a subset of HAM-D17. HAM-D6 score ranges from 0-22. The scale uses HAM-D17 items: 1, 2, 7, 8, 10 and 13. Item 13 is scored 0-2 and all others are scored 0-4.

Time Frame: Week 8 (or ET)
A HAM-D17 responder was defined as a participant with a 50% or greater decrease from baseline in HAM-D17 score. HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Individual 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.
Week 8 (or ET)
Number of Participants in Remission Based on the HAM-D17 at FOT Evaluation (Week 8 or ET)
Time Frame: Week 8 (or ET)
Remission was defined as a HAM-D17 score of less than or equal to 7. HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Individual 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.
Week 8 (or ET)
Number of Participants With a Response on the MADRS Score at FOT Evaluation (Week 8 or ET)
Time Frame: Week 8 (or ET)
A MADRS responder was defined as a participant with a 50% or greater decrease from baseline in MADRS score. It 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).
Week 8 (or ET)
Number of Participants With a Response on the CGI-I Score at FOT Evaluation (Week 8 or ET)
Time Frame: Week 8 (or ET)
CGI-I responder was defined as a participant with a score of 1 (very much improved) or 2 (much improved) on the CGI-I. CGI-I: 7-point clinician rated scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 (very much improved), 2 (much improved), or 3 (minimally improved) on the scale. Higher score = more affected.
Week 8 (or ET)

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Population Pharmacokinetics for Desvenlafaxine Plasma Concentrations
Time Frame: Week 2, 4 and 8 (or ET)
Relationship of demographic variables (age, gender, food, race, creatinine, aspartate aminotransaminase, alanine transaminase, bilirubin and concomitant medications) were examined by fitting measured DVS plasma concentrations to a 1 compartment model with first order absorption. Demographic variables were examined for clearance (CL/F), volume of distribution (V/F), Steady Area under Curve (AUC) using nonlinear mixed effects modeling. Final parameter estimates for demographic factors effecting CL/F, V/F and AUC were determined.
Week 2, 4 and 8 (or ET)
Change From Baseline in SDS at FOT Evaluation (Week 8 or ET)
Time Frame: Baseline and Week 8 (or ET)
SDS: a self-administered tool that measures functional impairment in 3 domains: Work/School, Social Life, and Family Life/Home Responsibilities. The participant rates the extent to which each of these domains is impaired by his/her symptoms using a 10 point visual analog scale: (0=not at all impaired, 10=extremely impaired) for a total maximum score of 30.
Baseline and Week 8 (or ET)
Change From Baseline in WHO-5 Total Score at FOT Evaluation (Week 8 or ET)
Time Frame: Baseline and Week 8 (or ET)
WHO-5 evaluates positive psychological well-being. WHO-5 consists of 5 questions and each is rated on a 6-point scale. The total score ranges from 0 to 25 (0= worst possible quality of life; 25=best possible quality of life).
Baseline and Week 8 (or ET)
Percentage of Participants With Sexual Dysfunction at FOT Evaluation (Week 8 or ET)
Time Frame: Week 8 (or ET)
ASEX scale includes 5 questions that evaluate sexual function exclusively during the week prior to completion in the following areas: libido, excitability and ability to reach orgasm. Sexual dysfunction=an ASEX total score of 19 or greater, or a score of 5 or greater on any item, or a score of 4 or greater on any 3 items. Participants who have had no sexual activity during the prior week should be instructed to not complete questions 3 through 5.
Week 8 (or ET)
Number of Participants With Categorical Scores on the C-SSRS at FOT Evaluation (Week 8 or ET)
Time Frame: Week 8 (or ET)
C-SSRS mapped into C-CASA(1-7) to assess whether participant:completed suicide(1),suicide attempt(2)(response of "Yes" on "Actual Attempt"),preparatory acts toward imminent suicidal behavior (3)("Yes" on "Preparatory Acts or Behavior"),suicidal ideation (4)("Yes" on "Wish to be dead","Non-Specific Active Suicidal Thoughts","Active Suicidal Ideation with methods without Intent to Act or Some Intent to Act,without Specific Plan or with Specific Plan and Intent),any suicidal behavior or ideation,self-injurious behaviour(7)("Yes" on "Has subject engaged in Non-suicidal Self-Injurious Behavior").
Week 8 (or ET)
Discontinuation-Emergent Signs and Symptoms (DESS) Total Score
Time Frame: Week 8 to 10 (or ET)
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.
