MeasureTime frameDescription
Change From Baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score to Week 8Baseline (At the start of double-blind treatment period), up to 8 weeksMADRS 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.

MeasureTime frameDescription
MADRS Remission at Week 8 (LOCF)Week 8Reported 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.
Change From Baseline in Hamilton Depression Scale (HAM-D17) Total Score to Week 8 (LOCF)Baseline (At the start of double-blind treatment period), up to 8 weeksThe 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.
Clinical Global Impressions-Improvement (CGI-I) Score at Week 8 (LOCF)Week 8The 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.
MADRS Response at Week 8 (Last Observation Carried Forward (LOCF))Week 8Reported 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.
Change From Baseline in Sheehan Disability Scale (SDS) Total Score to Week 8 (LOCF)Baseline (At the start of double-blind treatment period), up to 8 weeksThe 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.
Change From Baseline in Digit Symbol Substitution Test (DSST) Total Score to Week 8 (LOCF)Baseline (At the start of double-blind treatment period), up to 8 weeksThe 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.
Change From Baseline in Perceived Deficits Questionnaire (PDQ-5) Total Score to Week 8 (LOCF)Baseline (At the start of double-blind treatment period), up to 8 weeksPDQ-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.
Change From Baseline in Clinical Global Impressions-Severity (CGI-S) Score to Week 8 (LOCF)Baseline (At the start of double-blind treatment period), up to 8 weeksThe 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.
