About this study

Official title: Genetic Markers Associated With Response to Intravenous Ketamine

The Canadian Rapid Treatment Center of Excellence (CRTCE) is a healthcare facility principally focused on providing best practices of intravenous ketamine treatment to adult patients suffering from treatment resistant depression. Patients who have received IV ketamine at the clinic are eligible to participate in this study where genetic biomarkers are correlated with response to IV ketamine.

Being tested
Saliva Genetic Samples
Medical subject headings
Depressive Disorder, Treatment-Resistant

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Genetic Biomarkers

    Genetic markers associated with metabolism of IV ketamine will be assessed

    Measured: 1 month

  2. Quick Inventory of Depressive Symptomatology Self Report 16-Item

    The QIDS-SR16 is a self-report assessment used to evaluate depression severity in patients with a Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, diagnosis of Major Depressive Episode. In total, there are 16 individual questions evaluating 9 DSM domains. The highest score is 27, indicating severe depression, while the lowest score is 0, which would suggest a complete absence of depressive symptoms.

    Measured: Over 1-2 weeks

  3. Generalized Anxiety Disorder 7-item

    The GAD-7 is a 7 item self-report assessment used to evaluate symptoms of anxiety. The scale ranges from 0 (not at all) to 3 (nearly every day). To total score ranges from 0 suggesting a lack anxiety symptoms to 21, indicating severe anxiety.

    Measured: Over 1-2 weeks

  4. Snaith-Hamilton Pleasure Scale

    The SHAPS assessment is a 14 item self report tool used to measure anhedonia. Each item can be have a response of 1 (Definitely agree), 2(Agree), 3(Disagree), and 4(definitely disagree). The total score ranges from 14 to 56, in which higher scores on the assessment indicate higher levels of anhedonia.

    Measured: Over 1-2 weeks

  5. Sheehan Disability Scale

    The SDS contains 3 items, each ranging between zero to ten. The SDS is a self-reported assessment of disability within the context of depression. The total score ranges from 0, indicating no impairment, to 30, indicating severe impairment.

    Measured: Over 4 initial infusions

  6. Clinician Administered Dissociative States Scale

    The CADSS is a 23-item assessment administered by a clinician in order to evaluate dissociative symptoms. Each item is evaluated on a scale from 0, suggesting no dissociative symptom, to 4, suggesting extreme dissociation. In total, patients can score between 0 to 92, indicating extreme dissociation.

    Measured: Over 1-2 weeks

Secondary outcomes (7)
  1. Work Productivity and Activity Impairment Questionnaire (WPAI)

    WPAI is a questionnaire used to evaluate lost productivity due to depression. scores are presented as percentages (multiplying the scores by 100), with 0% representing no impact on productivity and 100% representing complete impact on productivity.

    Measured: 1 month

  2. Mystical Experience Questionnaire (MEQ)

    Mystical Experience Questionnaire (MEQ) is a self-report measure that has been used to assess the effects of hallucinogens in laboratory studies. Some studies suggest that mysticism may be associated with a response to ketamine. The MEQ is a 30 item questionnaire, with each item ranging from 0 to 5. A higher score denotes a strong mystical experience.

    Measured: 1 month

  3. Childhood Trauma Questionnaire (CTQ)

    The CTQ assesses five types of childhood trauma: 1)Emotional neglect 2) physical abuse 3) emotional abuse 4)physical neglect 5) sexual abuse.

    Each item being rated in 5 answer choice from 1 to 5 (never, rarely, sometimes, often or very often)

    Measured: 1 month

  4. UCLA Loneliness Scale (UCLA)

    20 item Self report scale measuring loneliness. Scales range from 0 to 60 with higher scores indicating a higher level of loneliness.

    Measured: 1 month

  5. Diet Screener Questionnaire

    Captures data regarding an individuals dietary habits over the past month

    Measured: 1 month

  6. Quality of Life Questionnaire (EQ-3D-5L)

    EQ-5D-5L measures health outcome self-completed by respondents. It consists of EQ-5D-5L descriptive system and EQ visual analogue scale (EQ-VAS). The descriptive system comprises of 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each has 5 levels (1-no problem, 2-slight problems, 3-moderate problems, 4-severe problems, 5-extreme problems). The responses are used to generate Health Status Index (HSI). HSI range is -0.148 to 0.949, is anchored at 0 (dead) and 1 (full health).

    Measured: 1 month

  7. Perceived Health Questionnaire (PHQ)

    PHQ-9 is 9-item, self-reported scale assessing 9 symptom domains of Diagnostic and Statistical Manual of Mental Disorders, Major Depressive Disorder criteria. Each item is rated on 4-point scale (0 = Not at all, 1 = Several Days, 2 = More than half days, 3 = Nearly every day). The scores are summed for a total score ranging from 0-27. Higher score indicates greater severity of depression. Severity of PHQ-9 categorized as follows: None-minimal (0-4), Mild (5-9), Moderate (10-14), Moderately Severe (15-19), Severe (20-27). The recall period is 2 weeks.

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

An observational study of Treatment Resistant Depression, run by Brain and Cognition Discovery Foundation at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Genetic Biomarkers (time frame: 1 month). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Aug 2021.
