Outcome Measures
Primary Outcomes (9)
Incidence of adverse events assessed by Clinical-Administered Dissociative Symptoms Scale (CADSS)
Incidence of adverse events will be assessed by Clinician-Administered Dissociative Symptoms Scale (change from baseline to each measure). Higher values represent a worse severity, but not necessarily outcome. The Clinical-Administered Dissociative Symptoms Scale has 23-items based on dissociative symptoms during the assessment. Each item is scored 0 (normal) to 4 (severe symptoms) with overall score ranges from 0 (normal) to 92 (severe symptoms). Total number of assessments:18 times
Baseline through week 5
Incidence of adverse events assessed by 4-items positive symptoms subscale of Brief Psychiatric Rating Scale (BPRS)
Incidence of adverse events will be assessed by 4-items positive symptoms subscale of Brief Psychiatric Rating Scale (change from baseline to each measure). Higher values represent a worse severity but not necessarily outcome. The 4-item positive symptoms subscale of Brief Psychiatric Rating Scale has 4-items based on conceptual disorganization, suspiciousness, hallucination and unusual thought content. Each item is scored 0 (normal) to 6 (severe symptoms) with overall score ranges from 0 (normal) to 24 (severe symptoms). Total number of assessments:18 times
Baseline through week 5
Incidence of adverse events assessed by body temperature (oral measurements)
Incidence of adverse events assessed by body temperature (oral measurement) in Celsius degree - change from baseline to each measure. A normal range is from 36.2 to 38.0 Celsius degrees; measurements beyond those ranges are clinically significant. The total number of measurements: 44 times
Baseline through week 5
Incidence of adverse events assessed by blood pressure
Incidence of adverse events assessed by blood pressure (after the participant has rested for at least 5 minutes) in mmHg - change from baseline to each measure. A normal range for systolic blood pressure is from 90 to 140 mmHg, for diastolic blood pressure is from 50 to 90 mmHg; measurements beyond those ranges are clinically significant. The total number of measurements: 44 times
Baseline through week 5
Incidence of adverse events assessed by respiration rate
Incidence of adverse events assessed by respiration rate in a breath number per minute - change from baseline to each measure. A normal range for respiration is from 12 to 16 breaths per minute; measurements beyond those ranges are clinically significant. The total number of measurements: 44 times
Baseline through week 5
Incidence of adverse events assessed by pulse
Incidence of adverse events assessed by pulse (beats per minute \[bpm\]) - change from baseline to each measure. A normal range for pulse is from 60 to 90 bpm; measurements beyond those ranges are clinically significant. The total number of measurements: 44 times
Baseline through week 5
Incidence of adverse events assessed by blood oxygen saturation
Incidence of adverse events assessed by blood oxygen saturation in percentage - change from baseline to each measure. A normal range for blood oxygen saturation is from 95 to 100 percentage; measurements under 95% are clinically significant. The total number of measurements: 44 times
Baseline through week 5
Incidence of adverse events assessed by weight
Incidence of adverse events assessed by weight in kilograms- change from baseline to each measure. Gain weight for 7% baseline weight is clinically significant. Total numbers of assessments: 2. Weight and height will be combined to report BMI in kg/m\^2
Baseline and week 5
Incidence of adverse events assessed by height
Incidence of adverse events assessed by height in meters. Total numbers of assessments: 1. Weight in kilograms and height in meters will be combined to report BMI in kg/m\^2
Baseline
Secondary Outcomes (1)
Change in severity of depression symptoms assessed by Montgomery-Asberg Depression Rating Scale (MADRS)
Baseline through week 5
Interventions
Ketamine will be infused (slow IV infusions of ketamine (0.5 mg/kg) over 40 minutes) twice weekly over a period of 4 weeks) Ketamine will be given in intranasal spray twice weekly over a period of 4 weeks Ketamine will be given orally (solution 2.0mg/kg, 2.5mg/kg) twice weekly over a period of 4 weeks.
Eligibility Criteria
Inpatients with TRD referred to the tertiary-reference unit for mood disorders
You may qualify if:
- Major depressive disorder (MDD) or bipolar disorder (BD) diagnosis as provided by DSM-5 criteria
- TRD defined as the patient does not reach remission within the 8 week trial of an antidepressant or combination at a therapeutic dose of at least two trials of first-line evidence-based treatments and/or electroconvulsive therapy (ECT)
You may not qualify if:
- Pregnancy and lactation
- Hypersensitivity to ketamine
- Uncontrolled hypertension
- Other uncontrolled somatic diseases that may impact safety per investigators judgement
