Arm && Interventions

Group	Intervention	Description
ASC-01	ASC-01	The dose of 3-12mg/100mg(Aripiprazole/Sertraline Combination)will be orally administered once daily
Placebo	Placebo	The dose of 0mg/100mg (Placebo/Sertraline Combination ）will be orally administered once daily

Primary Outcome Measures

Name	Time	Method
The Mean Change From Baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score	8 weeks after the start of the sertraline treatment period (Baseline), 6 weeks after the start of the double-blind period (Last Observation Carried Forward [LOCF])	The MADRS is a clinician-rated scale which evaluates the level of depression. The MADRS consists of 10 items assessing apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, suicidal thought. Each item is scored from 0 to 6, with higher scores indicating worse condition.Summed subscales are combined to compute a total score. Total score ranges from 0 to 60, with higher score indicating worse condition.

Secondary Outcome Measures

Name	Time	Method
The Montgomery-Åsberg Depression Rating Scale (MADRS) Response Rate	8 weeks after the start of the sertraline treatment period (Baseline), 6 weeks after the start of the double-blind period (Last Observation Carried Forward [LOCF])	The MADRS is a clinician-rated scale which evaluates the level of depression. The MADRS consists of 10 items assessing apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, suicidal thought. Each item is scored from 0 to 6, with higher scores indicating worse condition.; MADRS Response Rate is the percentage of subjects who achieved a decrease in the MADRS total score by 50% or more.
The Mean Change From Baseline in the Clinical Global Impression - Severity of Illness (CGI-S)	8 weeks after the start of the sertraline treatment period (Baseline), 6 weeks after the start of the double-blind period (Last Observation Carried Forward [LOCF])	The CGI-S Scale is a clinician-rated scale which assesses how mentally ill the patient is at the time. Scores range from 0 to 7: 0 = Not assessed, 1= Normal, not at all ill, 2 =Borderline mentally ill, 3= Mildly ill, 4= Moderately ill, 5= Markedly ill, 6= Severely ill, 7= Among the most extremely ill patients. Higher scores indicate worse condition.
The Mean Change From Baseline in the Apathy Scale (AS) Total Score	8 weeks after the start of the sertraline treatment period (Baseline), 6 weeks after the start of the double-blind period (Last Observation Carried Forward [LOCF])	The AS consists of 14 items. Items 1-8 are scored as follows: 3= Not at all, 2= Slightly, 1= Some, 0= A lot. Items 9-14 are scored as follows: 0= Not at all, 1= Slightly, 2= Some, 3= A lot. Total score ranges from 0-42, with higher score indicating worse condition.
The Montgomery-Åsberg Depression Rating Scale (MADRS) Remission Rate	8 weeks after the start of the sertraline treatment period (Baseline), 6 weeks after the start of the double-blind period (Last Observation Carried Forward [LOCF])	The MADRS is a clinician-rated scale which evaluates the level of depression. The MADRS consists of 10 items assessing apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, suicidal thought. Each item is scored from 0 to 6, with higher scores indicating worse condition.; MADRS Remission Rate is the percentage of subjects who achieved a decrease in the MADRS total score by 50% or more and whose MADRS total score is 10 points or less.
The Clinical Global Impression - Improvement (CGI-I) Improvement Rate	6 weeks after the start of the double-blind period (Last Observation Carried Forward [LOCF])	The CGI-I Scale is a clinician-rated scale which assesses the total improvement of the patient's condition compared to that at baseline. Scores range from 0 to 7: 0 = Not assessed, 1= Very much improved, 2 = Much improved, 3= Minimally improved, 4= No change, 5= Minimally worse, 6= Much worse, 7= Very much worse. Higher scores indicate worse condition. CGI-I Improvement Rate is the percentage of subjects whose CGI-I score is 1 or 2.
The Mean Change From Baseline in the Hamilton Depression Rating Scale 17 (HAM-D17) Total Score	8 weeks after the start of the sertraline treatment period (Baseline), 6 weeks after the start of the double-blind period (Last Observation Carried Forward [LOCF])	The HAM-D is a clinician-rated scale which evaluates the level of depression. The HAM-D consists of 17 items such as depression mood, feeling of guilt, suicide, insomnia, work and activities, retardation, and so on.; Each item is scored from 0 to 2, 3 or 4, with higher scores indicating worse condition. Summed subscales are combined to compute a total score. Total score ranges from 0 to 52, with higher score indicating worse condition.
The Mean Change From Baseline in the Social Adaptation Self-evaluation Scale (SASS) Total Score	8 weeks after the start of the sertraline treatment period (Baseline), 6 weeks after the start of the double-blind period (Last Observation Carried Forward [LOCF])	The SASS is a self-rating scale which assesses the social motivation and behavior in participants with depression. The SASS consists of 21 items covering the different aspects of social interactions, global social attitude, and self-perception. Each item is scored from 0 to 3, with higher scores indicating better condition.
The Mean Change From Baseline in the Self-rating Version of Montgomery-Åsberg Depression Rating Scale (MADRS-S) Total Score	8 weeks after the start of the sertraline treatment period (Baseline), 6 weeks after the start of the double-blind period (Last Observation Carried Forward [LOCF])	The MADRS-S is a patient-reported scale based on MADRS, administered to evaluate the level of depression. This scale consists of 9 items assessing patients' mood, feelings of unease, sleep, appetite, ability to concentrate, initiative, emotional involvement, pessimism and zest for life. Each item is scored from 0 to 3, with higher scores indicating worse condition. Summed subscales are combined to compute a total score.
