Change From Baseline at 60 Hours in the 17-Item Hamilton Rating Scale for Depression (HAM-D) Total Score |
The HAM-D Total Score comprises a sum of the 17 individual item scores. Items scored in a range of 0 to 2 include: insomnia (early, middle, late), somatic symptoms (gastrointestinal and general), genital symptoms, loss of weight, and insight. The following items are scored in a range of 0 to 4: agitation, depressed mood, feelings of guilt, suicide, work and activities, retardation, anxiety (psychic and somatic), and hypochondriasis. The Total Score can range from 0 to 52, and higher scores indicate a greater degree of depression. Higher scores indicate a greater degree of depression. A negative change from baseline indicates less depression. A positive change from baseline indicates more depression. |

Change From Baseline in HAM-D Bech 6 Subscale |
The HAM-D Bech 6 subscale score is calculated as the sum of the following six items: Item # 1 (depressed mood), Item # 2 (feelings of guilt), Item # 7 (work and activities), Item # 8 (retardation), Item # 10 (anxiety psychic), and Item # 13 (general somatic symptoms). Each item is scored in a range of 0 to 2 or 0 to 4, with higher scores indicating a greater degree of depression. The scores were transformed to a 100-point scale with a higher score indicating a greater degree of depression. A negative change from baseline indicates less depression. A positive change from baseline indicates more depression. |

The HAM-D comprises individual ratings of the following symptoms scored in a range of 0 to 2: insomnia (early, middle, late), somatic symptoms (gastrointestinal and general), genital symptoms, loss of weight, and insight. The following symptoms are scored in a range of 0 to 4: agitation, depressed mood, feelings of guilt, suicide, work and activities, retardation, anxiety (psychic and somatic), and hypochondriasis.

Change From Baseline at Key Time Points in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score |
The MADRS is a ten-item diagnostic questionnaire which psychiatrists use to measure the severity of depressive episodes in participants with mood disorders. It was designed as an adjunct to the HAM-D, to be more sensitive than the Hamilton Scale to the changes brought on by antidepressants and other forms of treatment. Each item yielded a score of 0 to 6. The MADRS total score was calculated as the sum of the 10 individual item scores, which ranged from 0 to 60. Higher MADRS scores indicates more severe depression. A negative change from baseline indicates less severe depression. A positive change from baseline indicates more severe depression. |

Percentage of Participants With Clinical Global Impression - Improvement (CGI-I) Response |
The CGI-I item employs a 7-point Likert scale to measure the overall improvement in the participant's condition post-treatment. The investigator rated the participant's total improvement whether or not it was due entirely to drug treatment. Response choices include: 0 = not assessed, 1 = very much improved, 2 = much improved, 3 = minimally improved, 4 = no change, 5 = minimally worse, 6 = much worse, and 7 = very much worse. The CGI-I was only rated at post-treatment assessments. By definition, all CGI-I assessments were evaluated against baseline conditions. CGI-I response was defined as having a score of 1 (very much improved) or 2 (much improved). |

Change From Baseline in the Generalized Anxiety Disorder 7-Item Scale (GAD-7) Total Score |
The GAD-7 is a participant-rated, generalized anxiety symptom severity scale. Scoring for GAD-7 generalized anxiety is calculated by assigning scores of 0 = "not at all sure," 1 = "several days," 2 = "over half the days," and 3 = "nearly every day" to the response categories. The GAD-7 total score for the seven items ranges from 0 to 21, where a score of 0 to 4 = minimal anxiety, 5 to 9 = mild anxiety, 10 to 14 = moderate anxiety, and 15 to 21 = severe anxiety. The GAD-7 total score was calculated as the sum of the seven individual item scores. A negative change from baseline indicates less anxiety. A positive change from baseline indicates more anxiety. |

Percentage of Participants With Treatment-Emergent Adverse Events |
An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A treatment-emergent AE (TEAE) is defined as an AE with onset on or after the start of study drug infusion, or any worsening of a pre-existing medical condition/AE with onset on or after the start of study drug infusion. |
