Current Primary Outcome Measures (submitted: January 10, 2020)

• Incidence of adverse events assessed by Clinical-Administered Dissociative Symptoms Scale (CADSS) [ Time Frame: Baseline through week 5 ]
  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
• Incidence of adverse events assessed by 4-items positive symptoms subscale of Brief Psychiatric Rating Scale (BPRS) [ Time Frame: Baseline through week 5 ]
  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
• Incidence of adverse events assessed by body temperature (oral measurements) [ Time Frame: Baseline through week 5 ]
  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
• Incidence of adverse events assessed by blood pressure [ Time Frame: Baseline through week 5 ]
  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
• Incidence of adverse events assessed by respiration rate [ Time Frame: Baseline through week 5 ]
  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
• Incidence of adverse events assessed by pulse [ Time Frame: Baseline through week 5 ]
  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
• Incidence of adverse events assessed by blood oxygen saturation [ Time Frame: Baseline through week 5 ]
  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
• Incidence of adverse events assessed by weight [ Time Frame: Baseline and week 5 ]
  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
• Incidence of adverse events assessed by height [ Time Frame: Baseline ]
  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

Current Secondary Outcome Measures (submitted: January 10, 2020)

Change in severity of depression symptoms assessed by Montgomery-Asberg Depression Rating Scale (MADRS) [ Time Frame: Baseline through week 5 ]

Change in severity of depression symptoms from baseline to each measure. Higher values represent a worse severity, but not necessarily outcome. The MADRS has 10-items which are based on mood symptoms over the past 7 days. Each item is scored 0 (normal) to 6 (severe depression) with overall score ranges from 0 (normal) to 60 (severe depression).

Descriptive Information

• Brief Title: A Naturalistic Study of Ketamine for Treatment Resistant Mood Disorders
• Official Title: A Naturalistic Study of Ketamine for Treatment Resistant Mood Disorders: Gdansk Depression Ketamine Project
• Brief Summary: This study aims to openly test the long-term safety, tolerability and effectiveness of repeated administration of IV, nasal spray and oral ketamine for treatment-resistant mood disorders.
• Detailed Description: Current pharmacological treatments for depression prove unsatisfactory efficacy with a proportion of subjects demonstrating treatment-resistant depression (TRD). The observation applies both to major depressive disorder (MDD) as well as bipolar I depression. There is growing evidence that the glutamatergic system plays a role in the pathophysiology and treatment of depression. Discovery of rapid, although transient antidepressant effect of ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist used in a single sub-anaesthetic intravenous dose in unipolar, bipolar and treatment-resistant patients provides evidence for a glutamatergic antidepressant. Subsequent studies confirmed this effect in repeated doses. Further research demonstrated that repeated ketamine infusions result in sustainable antidepressant effect with both, twice-weekly and thrice-weekly administration schedules. However, the worsening of depression may occur after infusions are completed. Given the risk of relapses, there is a definite need for the development of new strategies to maintain the beneficial effects of ketamine treatment. In the present study, the investigators aim to openly assess the safety, tolerability, and effectiveness of repeated, individually tailored IV, nasal spray and oral ketamine for treatment-resistant mood disorders. The investigators intend to explore questions regarding optimal dose, treatment frequency and duration.
