About this study

Official title: Exploratory Study of the Effects of Low-Dose Psilocybin on Sensory Processing, Neurophysiological Arousal, and Emotional Health

The purpose of the present study is to evaluate the feasibility, initial signals of efficacy, and potential mechanisms of action of "microdoses" of psilocybin (i.e., low doses of psilocybin that are not believed to produce mystical-type, transcendent, hallucinogenic, or other overtly salient subjective effects that limit functionality) in the treatment of moderate to severe demoralization (feelings of hopelessness and meaningless that frequently accompany medical illness and other life hardship).

Read the detailed description

Individuals who call research staff will undergo an initial telephone screen that will determine eligibility.

Week 1: Baseline Intake Appointment. Those who are eligible to participate on the basis of the telephone screen and provide informed consent will then complete a standard demographic questionnaire, a detailed psychiatric interview, and provide a urine sample for confirmation of substance abstinence and pregnancy status. Participants will then be administered a detailed medical history interview and physical examination including EKG and blood panel.

Week 2: Orientation. Participants who are medically eligible to participate will be scheduled for a psychoeducational orientation session that further explains the rationale of the study, and summarizes the study logistics. Participants will complete a number of baseline questionnaires and neuropsychological assessments at this time.

Week 3: Drug administration #1. In a between-groups design, participants will be randomized to receive 0 mg, 1 mg, 2.5 mg, or 5 mg of psilocybin at five weekly 6-hour long drug administration sessions. Dose will remain constant for each participant at each drug administration session.

At Drug Administration #1 and all subsequent drug administration sessions, participants will complete visual analogue scale (VAS) questions drawn from different sources that include drug abuse liability measures. These VAS questions will be administered at drug administration baseline and every 30 minutes thereafter through the end of acute effects at 6-hrs post-baseline. Research staff will complete a number of observational assessments at similar intervals.

Blood pressure will be assessed at regular intervals via automatic blood pressure monitor (i.e., at baseline and at 30, 60, 90, 120, 180, 240, and 360 min post-baseline), and medication for the treatment of acute hypertension will be administered should blood pressure exceed 200 systolic and/or 110 diastolic.

At peak drug effects (2 hr post-baseline), a number of measures will be administered, each differing by drug administration session. At Drug Administration #1, participants will undergo two electroencephalogram (EEG) tasks (with assessments at baseline serving as pre-drug control values).

At 6-hr post-baseline, participants will complete self-report measures assessing the subjective experience. These questionnaires will be administered at the conclusion of each drug administration session. Participants will then be administered a brief semi-structured qualitative interview designed to probe the nature of their experience. All participants will be required to arrange for transportation home from the CRU; participants will not be allowed to drive themselves after drug administration sessions.

Week 4: Drug Administration #2. This session will be identical to Drug Administration #1, however, at peak drug effects, participants will complete two new EEG tasks (with assessments at baseline serving as pre-drug control values).

Week 5: Drug Administration #3. This session will be identical to prior drug administration sessions, however, at peak drug effects, a neuropsychological measure will be administered.

Week 6: Drug Administration #4. This session will be identical to prior drug administration sessions, however, at peak drug effects, participants will complete another neuropsychological measure.

Week 7: Drug Administration #5. This session will be identical to prior drug administration sessions, however, at peak drug effects, participants will complete another neuropsychological measure. At the conclusion of this measure, subjects will undergo an EEG assessment (with an assessment at baseline serving as a pre-drug control value).

Week 8: Study Termination. This session will comprise completion of the same questionnaires that were previously completed at baseline as well as a semi-structured qualitative interview. EKG will be repeated at study termination.

It is noted that over the duration of the study, every day participants will be asked to complete some brief self-report measures and a resting state EEG via a smartphone app.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Psilocybin in people with Demoralization, run by University of Alabama at Birmingham 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 6 inclusion and 13 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 11 Mar 2026. 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. Some participants in this study may receive a placebo. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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?

Demoralization (time frame: Study Termination at Week 8). The study lists 14 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 11 Mar 2026.
