What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score to Week 8	MADRS is a 10-item clinician rated scale to measure overall severity of depressive symptoms (such as apparent sadness, reported sadness, inner tension). MADRS corresponds to core symptoms of depression, and rated on a 7-point Likert scale from 0 (symptoms absent) to 6 (severe depression) with a total possible score range from 0 to 60. Higher scores indicate greater severity of symptoms. A negative change from Baseline indicates improvement.	Baseline (At the start of double-blind treatment period), up to 8 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
MADRS Response at Week 8 (Last Observation Carried Forward (LOCF))	Reported data was percentage of participants who met MADRS response criteria (defined as a ≥50% decrease in the MADRS total score from Baseline) at Week 8 for each group. MADRS is a 10-item clinician rated scale to measure overall severity of depressive symptoms (such as apparent sadness, reported sadness, inner tension). MADRS corresponds to core symptoms of depression, and rated on a 7-point Likert scale from 0 (symptoms absent) to 6 (severe depression) with a total possible score range from 0 to 60. Higher scores indicate greater severity of symptoms. A negative change from Baseline indicates improvement.	Week 8
MADRS Remission at Week 8 (LOCF)	Reported data was percentage of participants who met MADRS remission criteria (defined as a MADRS total score ≤10) at Week 8 for each group. MADRS is a 10-item clinician rated scale to measure overall severity of depressive symptoms (such as apparent sadness, reported sadness, inner tension). MADRS corresponds to core symptoms of depression, and rated on a 7-point Likert scale from 0 (symptoms absent) to 6 (severe depression) with a total possible score range from 0 to 60. Higher scores indicate greater severity of symptoms. A negative change from Baseline indicates improvement.	Week 8
Change From Baseline in Hamilton Depression Scale (HAM-D17) Total Score to Week 8 (LOCF)	The HAM-D17 is a clinician-rated scale for assessing the severity of depression symptoms. The scores for each item range from 0 to 4 or 0 to 2, where 0 represents no symptoms. The rating is based on the past 7 days prior to the time of assessment. The total score ranges from 0 to 52 where a higher score indicates a greater depressive state.	Baseline (At the start of double-blind treatment period), up to 8 weeks
Clinical Global Impressions-Improvement (CGI-I) Score at Week 8 (LOCF)	The CGI-I assesses the participant's state of mental illness improvement. The participant's condition compared to baseline is rated on a seven-point scale (1=very much improved ~ 7=very much worse). Higher scores indicate greater worsening of illness. Values closest to 1 for this outcome measure indicate the greatest improvement of symptoms.	Week 8
Change From Baseline in Clinical Global Impressions-Severity (CGI-S) Score to Week 8 (LOCF)	The CGI-S assesses the impression of the participant's current state of mental illness. The current severity of mental illness is rated on a seven-point scale (1=normal, not ill at all ~ 7=most extremely ill) based on a total clinical experience. Higher scores indicate greater severity of mental illness.	Baseline (At the start of double-blind treatment period), up to 8 weeks
Change From Baseline in Sheehan Disability Scale (SDS) Total Score to Week 8 (LOCF)	The SDS assesses functional impairment in 3 domains: work/school, social life or leisure activities, and home life or family responsibilities. The participant rates the extent to which each aspect is impaired on a 10-point visual analog scale, from 0 (not at all) to 10 (extremely). The 3 scores are added together to calculate the total score, which ranges from 0 to 30, with higher scores indicating more impairment.	Baseline (At the start of double-blind treatment period), up to 8 weeks
Change From Baseline in Digit Symbol Substitution Test (DSST) Total Score to Week 8 (LOCF)	The DSST is a neuropsychological test to assess cognitive function. Participants are required to copy symbols that are paired with simple geometric shapes or numbers within a specific time for a total possible score of 0 to 133. Higher scores-correct number of symbols reflects greater objective cognitive functioning. An increase in score represents an improvement in an integrated measure of cognitive function.	Baseline (At the start of double-blind treatment period), up to 8 weeks
Change From Baseline in Perceived Deficits Questionnaire (PDQ-5) Total Score to Week 8 (LOCF)	PDQ-5 is a self-administered 5-item questionnaire to assess cognition function, including subscales of attention/concentration, retrospective memory, prospective memory, and planning/organization. PDQ-5 total score ranges from 0 to 20 with smaller scores indicate greater cognitive function.	Baseline (At the start of double-blind treatment period), up to 8 weeks
