Study summary

Postpartum depression is a non-psychotic major or minor depressive episode that occurs during pregnancy or within 12 months of post-partum period. The nature of symptoms is same as depressive episode characterized by depressed mood, anxiety, sleep difficulties, suicidal thoughts, tiredness and diminished interest in pleasurable activities. Severe maternal depression affects children by increasing the risk of emotional and behavioral and physical health problems and cognitive difficulties. Thus early screening and intervention is critical in reducing the negative impact of PND in the mother and child, family and the community.

The purpose of this study is to assess the safety, pharmacokinetics and antidepressant efficacy of sub-anesthetic dose of intravenous ketamine in perinatal depression.

What researchers measure

Primary outcomes

  1. Change in Depressed Mood as Indicated by Hamilton Depression Rating Scale (HAM-D) Score

    The Hamilton Depression Rating Scale (HAM-D) score ranges from 0-53. A score of 0-7 is generally accepted to be within the normal range (or in clinical remission), while a score of 20 or higher indicates at least moderate severity of depressive symptoms. The value reported is the score at baseline minus the score 24 hours post-injection.

    Time frame: baseline, 24 hours post-injection

Secondary outcomes

  1. Number of Treatment-Emergent Adverse Events

    Time frame: 24 hours post-injection

  2. Change in Postnatal Depression as Indicated by Edinburgh Postnatal Depression Scale (EPDS) Scale

    The Edinburgh Postnatal Depression Scale (EPDS) score ranges from 0 to 30. Higher scores indicate worse outcome, with a score of 10 or greater indicating depression. The value reported is the score at baseline minus the score at 24 hours post-injection.

    Time frame: baseline, 24 hours post-injection

  3. Change in Anxiety as Indicated by Generalized Anxiety Disorder 7-Item (GAD-7) Scale

    The Generalized Anxiety Disorder 7-Item (GAD-7) Scale score ranges from 0 to 21, with higher scores indicating greater anxiety. The value reported is the score at baseline minus the score 24 hours post-injection.

    Time frame: baseline, 24 hours post-injection

  4. Change in Depression as Indicated by Patient Health Questionnaire (PHQ-9)

    The Patient Health Questionnaire (PHQ-9) score ranges from 0 to 27, with greater scores indicating more severe depression.

    Time frame: baseline, 24 hours post-injection

  5. Change in Behavioral Suicidal Events (Suicidal Ideation), as Assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS)

    The C-SSRS is a suicidal ideation and behavior rating scale with yes/no responses. The first part (Items 1-5) rates an individual's degree of suicidal ideation on a 0-5 scale, ranging from "wish to be dead" to "active suicidal ideation with specific plan and intent and behaviors". The C-SSRS outcomes are categories and have binary responses (yes/no). Suicidal ideation is considered when the patient responds a "yes" answer at any time during treatment to any one of the five suicidal ideation questions (Categories 1-5) on the C-SSRS. The sum of the 5 intensity item scores create a total score (range 0 to 25) to represent the intensity rating (higher scores indicate more severe suicidal ideation).

    Time frame: baseline, 24 hours post-injection

  6. Change in Behavioral Suicidal Events (Suicidal Behavior), as Assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS)

    The questions 6-10 of the C-SSRS are related to suicidal behavior, and the outcome is a simple yes/no response. Suicidal behavior occurs if the patient answers a "yes" at any time during treatment to any one of the five suicidal behavior questions (Categories 6-10) on the C-SSRS.

    Time frame: baseline, 24 hours post-injection
