Double-Blind (DB) Treatment Phase: Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score From Day 1 to the End of the 4-Week Double-Blind Treatment Phase
The MADRS is a clinician-rated scale designed to measure depression severity and detects changes due to antidepressant treatment. The scale consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total possible score of 60. Higher scores represent a more severe condition.
Time frame: Baseline (Day 1 [prerandomization]) up to end of the 4-Week DB treatment phase (Day 28)

DB Treatment Phase: Change From Baseline in Anhedonia Symptoms Over Time to the End of the 4-Week DB Treatment Phase As Assessed by MADRS Anhedonia Factor Score
Change from baseline in anhedonia symptoms over time to the end of the 4-week DB treatment phase as assessed by MADRS anhedonia factor score will be reported. The MADRS anhedonia factor is a widely used 5-item subscale of the MADRS used to specifically measure the lack of pleasure (anhedonia) in depression, combining items for apparent sadness, reported sadness, concentration difficulties, lassitude (tiredness), and inability to feel. The sum of these five items (each scored 0-6), resulting in a score from 0 to 30, with higher scores indicating more severe anhedonia. This score helps assess treatment effectiveness for anhedonia, correlates with functional improvement, and provides a deeper look beyond the total depression score, showing significant clinical relevance in major depressive disorder (MDD) trials.
