Purpose
The primary objective of this study is to evaluate the long-term safety of desvenlafaxine succinate sustained release tablets during 10-month open-label treatment of Japanese subjects with major depressive disorder (MDD).
The secondary objective is to evaluate the long-term response of subjects receiving desvenlafaxine succinate sustained release tablets by clinical global evaluation, general well-being and absence of symptoms.

Primary Outcome Measures:
- Change From Baseline in Hamilton Psychiatric Scale for Depression-17 Item (HAM-D17) Score [ Time Frame: Baseline (Extension Study) up to Day 308 or Final On-Therapy (FOT) Evaluation ] [ Designated as safety issue: No ]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. Higher scores indicate greater severity. FOT evaluation is defined as the last "on-therapy" evaluation, regardless of the number of days on therapy. Analysis on Observed cases (non-missing data) and Last observation carried forward (LOCF); LOCF method of imputation for any missing value at any visit.
- Percentage of Participants With Adverse Events (AEs) or Serious Adverse Events (SAEs) [ Time Frame: Baseline (Extension Study) up to Day 329 or 15 days after last dose of study treatment ] [ Designated as safety issue: Yes ]Any untoward medical occurrence in a participant who received study treatment was considered an AE without regard to possibility of causal relationship. An AE resulting in any of the following outcomes, or deemed to be significant for any other reason, was considered to be an SAE: death; initial or prolonged inpatient hospitalization; a life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly.
Secondary Outcome Measures:
- Number of Participants With Categorical Scores on Clinical Global Impression-Improvement (CGI-I) [ Time Frame: Day 308 or FOT Evaluation ] [ Designated as safety issue: No ]CGI-I is a 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.
- Change From Baseline in Clinical Global Impression-Severity of Illness [CGI-S] Score [ Time Frame: Baseline (Extension Study) up to Day 308 or FOT Evaluation ] [ Designated as safety issue: No ]CGI-S is a 7-point clinician rated scale to assess severity of current illness state. Range is 1 (normal - not ill at all) to 7 (among the most extremely ill). Higher score = more affected.

Criteria
Inclusion Criteria:
- Outpatients who have completed double-blind therapy in short-term study for the indication of major depressive disorder (MDD), including scheduled evaluations, with no major protocol violations and no study events that, in the opinion of the investigator, would preclude the subject's entry into the long-term, open-label study.
Exclusion Criteria:
- Clinically important abnormalities on baseline (day 56 of the short-term study) physical examination, or any unresolved clinically significant abnormalities on electrocardiogram (ECG), laboratory test results, or vital signs recorded before day 56 in the previous short-term study for the indication of MDD.
