Psilocybin for Methamphetamine Use Disorder

2026年8月17日 更新者:Peter Hendricks

Psilocybin in the Treatment of Methamphetamine Use Disorder

This trial tests whether psilocybin-assisted treatment can help adults stop using methamphetamine. Participants receive a single oral dose of psilocybin during a supervised session, paired with brief cognitive behavioral therapy, and are followed for up to six months. The study is supported by the HEAL Initiative (https://www.nih.gov/heal).

詳細な説明

Single-site, phased UG3/UH3 randomized, quadruple-masked, parallel-group controlled trial (target N = 42). Participants are randomized 1:1 to a single administration of psilocybin at one of two dose levels, each delivered with a manualized platform of two preparation and two integration sessions. The specific doses are withheld in this registration during the conduct of the trial to preserve masking and reduce expectancy effects, and will be reported with results. The UG3 phase (n = 12) establishes feasibility and safety; the UH3 phase (n = 30) expands enrollment with longer follow-up. Support is provided by the HEAL Initiative (https://www.nih.gov/heal).

実験的:Psilocybin, Dose A
Single oral dose during an 8-hour supervised session (Specific dose withheld during conduct).
The specific doses (in mg) are intentionally omitted from this registration during the conduct of the trial to preserve masking and reduce expectancy effects. The doses will be disclosed when results are reported after primary completion, by which point participants have been debriefed.

Complete abstinence from methamphetamine (Timeline Followback, urine-confirmed); a dichotomous (yes or no) outcome where no use whatsoever during the assessment period is coded as "yes" and any use at all during the assessment period is coded as "no."
Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
Methamphetamine Use Disorder in Remission
時間枠:30/90-day (UG3), 30/90/180-day (UH3)
Modified DSM-5 Methamphetamine Use Disorder in early remission (SCID-5); a dichotomous (yes or no) outcome where those who meet DSM-5 criteria for Methamphetamine Use Disorder in early remission are coded as "yes" and those who do not meet DSM-5 criteria for Methamphetamine Use Disorder in early remission are coded as "no."
30/90-day (UG3), 30/90/180-day (UH3)
Health-related Quality of Life
時間枠:Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
Health-related quality of life as measured by the RAND-36 self-report measure. The RAND-36 contains 8 primary health scales (Physical functioning, Role limitations due to physical health, Role limitations due to emotional problems, Social functioning, Emotional well-being [mental health], Energy/fatigue [vitality], Bodily pain, and General health perception) and 2 summary scales (Physical Health Summary and Mental Health Summary) with possible scores for each scale ranging from 0 to 100. Higher scores represent better health states and outcomes.
Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
Self-perceived Quality of Life
時間枠:Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
Self-perceived quality of life as measured by the WHOQOL-BREF self-report measure. This measure includes 4 scales (Physical, Psychological, Social, and Environment), each with a possible range from 0 to 100. Higher scores indicate a better quality of life.
Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
Craving
時間枠:Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
Craving, as measured by the Stimulant Craving Questionnaire-Brief (STCQ-Brief), a 10-item self-report tool measuring present-moment craving for stimulants. A score is calculated by averaging all 10 items, with a possible range of 0 to 6. Higher mean scores reflect more severe craving.
Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
Withdrawal
時間枠:Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
Methamphetamine withdrawal as measured by the Amphetamine Cessation Symptom Assessment (ACSA), a 16-item clinical rating tool used to measure the severity of amphetamine withdrawal symptoms over the preceding 24 hours. Scores range from 0 to 64, with higher scores reflecting more severe withdrawal symptoms.

Severity of Dependence
時間枠:Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
Severity of methamphetamine dependence, as measured by the Stimulant Use Disorder Severity Scale (StUDSS). The StUDSS is a new patient-reported outcome instrument measuring the severity of symptoms for stimulant use disorder. Total symptom severity is based on a sum of all items, with a possible range of 0 to 44. Higher scores reflect more severe dependence. The StUDSS also yields a categorical severity rating based on total criteria count: Mild (2 or 3 criteria), Moderate (4 or 5 criteria), or Severe (6 or more criteria).

The MEQ yields 4 scales: Unity, Positive Mood, Transcendence of Time and Space, and Ineffability. Possible scores for each scale range from 0 to 5 and greater scores reflect higher intensity and greater depth of the mystical experience.
Day of dosing (≈7 hours)
Challenging Experience
時間枠:Day of dosing (≈7 hours)
Challenging experience during the day of dosing as measured by the Challenging Experience Questionnaire (CEQ). The CEQ yields 7 scales: Fear, Grief, Physical Distress, Insanity, Isolation, Death, and Paranoia. Possible scores range from 0 to 5, with greater scores reflecting higher intensity and more severe degree of psychological or physical distress during the experience
Day of dosing (≈7 hours)
Emotional Breakthrough

The total overall score is calculated as the sum of all six items, yielding a total summed score ranging from 0 to 600. Greater scores on the EBI reflect a deeper, more complete sense of psychological resolution and catharsis.
Day of dosing (≈7 hours)
Psychological Insight
時間枠:Day of dosing (≈7 hours)
Psychological insight during the day of dosing as measured by the Psychological Insight Questionnaire (PIQ). The PIQ measure insight on 2 scales: Avoidance and Maladaptive Patterns Insights and Goals and Adaptive Patterns Insights. Scores on the 2 scales range from 0 to 5, with greater scores representing a higher intensity of acute psychological realizations gained during the experience.

個々の参加者データ (IPD) の計画

個々の参加者データ (IPD) を共有する予定はありますか?

はい

IPD プランの説明

De-identified individual participant data, metadata, and a data dictionary will be shared through an NIH-designated repository accessible via the HEAL Data Ecosystem, consistent with the study's Data Management and Sharing Plan and the HEAL Public Access and Data Sharing Policy.

IPD 共有時間枠

De-identified individual participant data and the supporting documents will become available no later than publication of the primary outcome results or the end of the funding period, whichever comes first, and will remain available indefinitely thereafter through the repository.

IPD 共有アクセス基準

Data will be deposited in an NIH-designated repository accessible through the HEAL Data Ecosystem. Qualified researchers may request the de-identified dataset, data dictionary, and supporting documents through the repository's data-access process. Because these are substance use disorder data, access may be controlled or registered under the repository's terms and the Certificate of Confidentiality, and a data use agreement may be required.
