Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Investigator-administered MADRS Total Score From Baseline BTRX-246040 and Placebo	The Investigator-administered MADRS includes 10 items assessing the following symptoms: apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. Each item is scored from 0 (absence of symptom) to 6 (severe symptom); the overall score ranges from 0 to 60. MADRS total scores from 0 to 6 indicate normal/symptom absent, from 7 to 19 indicate mild depression, from 20 to 34 indicate moderate depression, and from 35 to 60 indicate severe depression.	Week 8
Secondary	Change From Baseline in Investigator-administered MADRS-6 Total Score	The Investigator-administered MADRS-6 subscale focuses on the core symptoms of depression and assesses the following symptoms: apparent sadness, reported sadness, inner tension, lassitude, inability to feel, and pessimistic thoughts. Each item is scored from 0 (absence of symptom) to 6 (severe symptom); the overall score ranges from 0 to 36. The change from baseline in the Investigator-administered MADRS-6 subscale was analyzed using the same method as the MADRS efficacy endpoint, substituting the baseline MADRS-6 subscale as the covariate in place of the MADRS total score.	Week 8
Secondary	Change From Baseline in Investigator-administered HADS-A (Hospital Anxiety and Depression Scale - Anxiety Subscale) Score	The Investigator-administered Hospital Anxiety and Depression Scale (HADS) subscales comprises of 7 questions regarding Depression and 7 questions regarding Anxiety. Each question is rated on a scale from 0 - 3. The outcome of the HADS questionnaire is two total scores, the HADS-A (for anxiety) and the HADS-D (for depression). Both total scores are graded on a scale of 0 - 21 and can be categorized as Normal (0 - 7), Borderline Abnormal (8 - 10) and Abnormal (11 - 21). Higher scores indicate higher levels of anxiety and depression.	Week 8
Secondary	Change From Baseline in Investigator-administered HADS-D (Hospital Anxiety and Depression Scale - Depression Subscale) Score	The Investigator-administered Hospital Anxiety and Depression Scale (HADS) subscales comprises of 7 questions regarding Depression and 7 questions regarding Anxiety. Each question is rated on a scale from 0 - 3. The outcome of the HADS questionnaire is two total scores, the HADS-A (for anxiety) and the HADS-D (for depression). Both total scores are graded on a scale of 0 - 21 and can be categorized as Normal (0 - 7), Borderline Abnormal (8 - 10) and Abnormal (11 - 21). Higher scores indicate higher levels of anxiety and depression.	Week 8
Secondary	Change From Baseline in Investigator-administered Dimensional Anhedonia Rating Scale (DARS)	The Investigator-administered Dimensional Anhedonia Rating Scale (DARS) is a 17-item questionnaire with each answer between 0 and 4 on a Likert scale grading (0=Not at all, 1=Slightly, 2=Moderately, 3=Mostly, 4=Very Much). Therefore, the DARS total score is on a scale of 0 - 68. The DARS Total score is broken down into four dimensions; Hobbies, Food/Drink, Social Activities and Sensory Experience.	Week 8
Secondary	Change From Baseline in Investigator-administered Snaith-Hamilton Pleasure Scale (SHAPS) Score	The Investigator-administered Snaith Hamilton Pleasure Scale (SHAPS) is a 14-item questionnaire. The SHAPS is scored two different ways. Under the original scoring method, each question has 4 responses, 2 of which imply agreement (Definitely Agree, Agree; each scored as 0) and 2 which imply disagreement (Disagree, Strongly Disagree; each scored as 1). Therefore, the SHAPS total score ranges 0 - 14. In this study, in addition to the traditional scoring method, an alternative scoring method will assign 1 - Strongly Agree, 2 - Agree, 3 - Disagree, and 4 - Strongly Disagree. Using this alternative scoring method, the total score ranges 14-56. In both scoring systems, higher scores indicate greater anhedonia.	Week 8
