The primary purpose of this study is to evaluate if the effectiveness of desvenlafaxine succinate sustained-release tablet (50 mg/day) used for 8 weeks is not inferior to duloxetine hydrochloride enteric-coated capsule (60 mg/day) in adult patients with major depressive disorder.
This is a multicenter study to evaluate if the effectiveness of desvenlafaxine succinate sustained-release tablet (50 mg/day) used for 8 weeks is not inferior to duloxetine hydrochloride enteric-coated capsule (60 mg/day) in adult patients with major depressive disorder. A total of 400 subjects will be randomly allocated to experimental arm (desvenlafaxine succinate sustained-release tablet) and active comparator arm (duloxetine hydrochloride enteric-coated capsule) in a 1:1 ratio.

| Hamilton Rating Scale for Depression, 17-item (HAM-D17) Remission Rate | Hamilton Rating Scale for Depression, 17-item 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). Each item is scored on either a 3 point (0 to 2) or a 5 point scale (0 to 4), for a maximum total score of 52; higher scores indicate more depression.

| Change From Baseline on the Hamilton Rating Scale for Anxiety (HAM-A) Total Score | The Hamilton Anxiety Rating Scale (HAM-A) is a clinician-administered scale which consists of 14 items, each rated on a five point scale ranging from 0 (not present) to 4 (very severe). The highest possible score is 56, which represents the most severe form of anxiety; the lowest possible score is 0, which represents an absence of anxiety. | Baseline to Week 8 |
| Change From Baseline on the Clinical Global Impression Scale-Improvement (CGI-I) | Clinical Global Impression Scale-Improvement (CGI-I): 7-point clinician rated scale ranging from 1 (very much improved) to 7 (very much worse). Higher score = worse outcome. | Baseline to Week 8 |
| Change From Baseline on the Clinical Global Impression-Severity Score (CGI-S) | Clinical Global Impression-Severity Score (CGI-S): 7-point clinician rated scale to assess severity of participant's current illness state; range: 1 (normal - not ill at all) to 7 (among the most extremely ill patients). Higher score = worse state. | Baseline to Week 8 |
| Change From Baseline on the Visual Analog Scale (VAS) for Pain | The pain level was assessed with the Visual Analog Scale, which consists of a horizontal line of 10 cm in length. For pain level assessment, "0" defines "no pain" and "10" defines "unbearable pain''. The participants are asked to mark the intensity of their pain level. | Baseline to Week 8 |
