About this study

Official title: Unraveling the Aesthetic Mind in Anhedonia, Insights From Pharmacological Imaging of the Human Brain: A Single-blind, Randomized, Placebo-controlled Cross-over Study

The aim of this study is to assess the impact of ketamine on aesthetic perception and processing. This study assesses the role of these effects in facilitating ketamine's antidepressant properties, with a focus on anhedonia. To address this aim, 25 patients with major depressive disorder and 35 healthy controls will be assessed twice with magnetic resonance imaging, once after administration of intravenous ketamine (subanesthetic dose) and once after administration of placebo.This study has a single-center, placebo-controlled, cross-over study design. During MRI, structural, resting state, and functional imaging will be performed. Functional imaging will comprise aesthetic processing, reward, and sexual arousal paradigms. In addition, various neuropsychological scales assessing depressive symptoms, anhedonia, and aesthetic processing will be performed. Eligibility for participation will be assessed during a screening visit, a follow up visit will end study participation.

What is being measured

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

  1. BOLD signal assessed with fMRI during aesthetic paradigm

    Difference in Blood Oxygen Level Dependent (BOLD) signal assessed with functional magnetic resonance imaging (fMRI) between ketamine and placebo condition during an aesthetic processing task

    Measured: Change from baseline to up to 4 weeks

  2. BOLD signal assessed with fMRI during reward paradigm

    Difference in Blood Oxygen Level Dependent (BOLD) signal assessed with functional magnetic resonance imaging (fMRI) between ketamine and placebo condition during a reward processing task

    Measured: Change from baseline to up to 4 weeks

  3. BOLD signal assessed with fMRI during sexual arousal paradigm

    Difference in Blood Oxygen Level Dependent (BOLD) signal assessed with functional magnetic resonance imaging (fMRI) between ketamine and placebo condition during a sexual arousal paradigm

    Measured: Change from baseline to up to 4 weeks

  4. Levels of pleasantness assessed during aesthetic fMRI task

    Level of pleasantness (Numbered scale) of aesthetic stimuli during aesthetic paradigm task

    Measured: Change from baseline to up to 4 weeks

  5. Number of of chills assessed during aesthetic fMRI task

    Number of chills in response to aesthetic stimuli during aesthetic paradigm task

    Measured: Change from baseline to up to 4 weeks

  6. BOLD signal assessed with fMRI during resting state

    Difference in Blood Oxygen Level Dependent (BOLD) signal assessed with functional magnetic resonance imaging (fMRI) between ketamine and placebo condition during resting state

    Measured: Change from baseline to up to 4 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ketamine in people with Major Depressive Disorder, run by Medical University of Vienna at 1 site in Austria.

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 6 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 15 Apr 2024. 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 Austria. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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

Contact Rupert Lanzenberger, MD (0043 1 40400 ext. 35760, rupert.lanzenberger@meduniwien.ac.at), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

BOLD signal assessed with fMRI during aesthetic paradigm (time frame: Change from baseline to up to 4 weeks). 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?

On the ClinicalTrials.gov record for NCT05320107, which also lists 1 linked publication.

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 15 Apr 2024.
