What is being measured

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

  1. Change in Massachusetts General Hospital Rumination Questionnaire (MGH-RQ)

    A transdiagnostic state measure of rumination over the previous two weeks consisting of 9 items on a 5 point Likert scale from 0 (Never/Rarely) to 4 (All The Time).

    Measured: Baseline, and 3 weeks, 6 weeks, 9 weeks, and 12 weeks after psilocybin administration.

  2. Change in Resting-State Functional Connectivity

    Changes in resting-state activity during functional magnetic resonance imaging(fMRI) scans.

    Measured: Baseline, day of psilocybin administration, and 3 weeks, and 12 weeks after psilocybin administration.

  3. Change in Self-Attribution Task performance

    Participants are shown words one at a time and asked to answer if each of the words apply to 'Self' or 'Other'

    Measured: Baseline, day of psilocybin administration, and 3 weeks, and 12 weeks after psilocybin administration.

  4. Change in Task-Based Activity during Self-Attribution Task

    Changes in task-based activity during functional magnetic resonance imaging(fMRI) scans.

    Measured: Baseline, day of psilocybin administration, and 3 weeks, and 12 weeks after psilocybin administration.

Secondary outcomes (12)
  1. Change in Montgomery-Asberg Depression Rating Scale(MADRS)

    The MADRS is a clinician-rated scale measuring depression severity, consisting of 10 items, each scored from 0 (normal) to 6 (severe), for a total possible score of 60; higher scores denote greater severity.

    Measured: Baseline, the day before psilocybin administration and at 1 day, 1 week, 2 weeks, 3 weeks, 6 weeks, 9 weeks and 12 weeks after psilocybin administration.

  2. Change in Quick Inventory of Depressive Symptomatology - 16 item (QIDSR-SR-16)

    The 16-item QIDS-SR-16 a self-rated scale designed to assess the severity of depressive symptoms in the nine diagnostic symptom domains of a major depressive episodes, exclusive of atypical or melancholic symptoms. The QIDS-SR-16 is sensitive to change with various treatments, demonstrating its utility in research settings. The total score ranges from 0 to 27 with 0 representing no depression and 27 representing severe depression.

    Measured: Baseline, the day before psilocybin administration and at 1 day, 1 week, 2 weeks, 3 weeks, 6 weeks, 9 weeks and 12 weeks after psilocybin administration.

  3. Change in Positive and Negative Affect Schedule (PANAS)

    The PANAS measures the acute emotional drug effects and comprises 2 mood scales that measure positive and negative affect. Participants respond to 20 items using a 5-point scale that ranges from "slightly or not at all (1)" to "extremely (5)". A total higher score on the positive affect questions indicates more of a positive affect while a lower score on the negative affect questions indicates less of a negative affect.

    Measured: Baseline, the day of psilocybin administration and at 3 weeks and 12 weeks after psilocybin administration.

  4. Change in Hamilton Depression Rating Scale - 17 item (HAM-D-17)

    The HAM-D-17 is a 17 item scale used to assess the degree of symptom severity in depressed patients.

    Measured: Baseline and 3 weeks and 12 weeks after psilocybin administration.

  5. Change in Ruminative Response Scale (RRS)

    A self-report measure of describing one's responses to depressed mood, consists of 22 items and three factors (Depression, Brooding, and Reflection). Each item is rated on a 4-point Likert scale ranging from 1 (never) to 4 (always). The total score ranges from 22 to 88, with higher scores indicating higher tendency to ruminate, i.e. higher trait rumination.

    Measured: Baseline and 12 weeks after psilocybin administration.

  6. Change in Rumination Reflection Questionnaire (RRQ)

    The RRQ measures the extent to which a person tends to ruminate or engage in self-reflection. It consists of 24 items measured on a 5 point Likert scale from 1 (Strongly Disagree) to 5 (Strongly Agree),12 items which assess the tendency to ruminate, and 12 items which assess the tendency to engage in self reflection.

    Measured: Baseline and 12 weeks after psilocybin administration.

  7. Change in Penn State Worry Questionnaire (PSWQ)

    The PSWQ is a 16-item questionnaire that aims to measure the trait of worry, using Likert rating from 1 (not at all typical of me) to 5 (very typical of me). The PSWQ attempts to measure the excessiveness, generality, and uncontrollable dimensions of worry.

    Measured: Baseline and 12 weeks after psilocybin administration.

  8. Change in NEO-Five-Factor Inventory (NEO-FFI)

    The NEO-FFI is a 60-item psychological personality inventory that assesses based on the five- factor model: Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Participants are asked to select the response that best represents their opinion on a 5-point scale: 0-Strongly Agree, 1-Agree, 2-Neutral, 3-Disagree, 4-Strongly Disagree.

    Measured: Baseline and 12 weeks after psilocybin administration.

  9. Change in Behavior Rating Inventory of Executive Function - Adult Version (BRIEF)

    The BRIEF is a 75-item scale designed to assess executive function and self-regulation. Participants choose how often certain behaviors were problematic over the past month N-never, S-sometimes, O-often.

    Measured: Baseline and 12 weeks after psilocybin administration.

  10. Change in Cognitive Flexibility Inventory (CFI)

    The CFI is a brief self-report measure of the type of cognitive flexibility necessary for individuals to successfully challenge and replace maladaptive thoughts with more balanced and adaptive thinking. The measure consists of 20 items and participants indicate the extent to which they agree or disagree with the statements in the items, on a scale from 1-Strongly Disagree to 7-Strongly Agree.

    Measured: Baseline and 12 weeks after psilocybin administration.

  11. Change in Emotional Faces Flanker Task

    This task examines executive functioning as it assesses the ability to ignore/inhibit irrelevant flanking information in order to respond to the central task.

    Measured: Baseline, day of psilocybin administration, and 3 weeks and 12 weeks after psilocybin administration.

  12. Change in Depression Implicit Attitudes Task (IAT)

    The IAT provides a measure of the strength of association between four categories by pairing two concept categories (e.g., Me/Not-Me) with two attribution categories (e.g., Happy/Sad).

    Measured: Baseline, day of psilocybin administration, and 3 weeks and 12 weeks after psilocybin administration.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Psilocybin in people with Treatment-Resistant Major Depressive Disorder, run by Massachusetts General Hospital at 1 site in United States.

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 11 inclusion and 19 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: withdrawn, as of the sponsor's last update on 24 Jan 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 United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Change in Massachusetts General Hospital Rumination Questionnaire (MGH-RQ) (time frame: Baseline, and 3 weeks, 6 weeks, 9 weeks, and 12 weeks after psilocybin administration.). The study lists 4 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 24 Jan 2024.
