About this study

Phase I safety and dose finding study of a standardized Ayahuasca analog (SM-001) in healthy adult volunteers

Read the detailed description

The Investigational New Drug SM-001 is formulated as a hot water decoction of two clonal cultivars of the Peruvian plants, Banisteriopsis caapi (BC) and Psychotria viridis (PV). It represents a modern formulation of an ancient Amazonian botanical medicine, "ayahuasca" ("vine of the soul") that is used by many native South American indigenous and mestizo groups for both religious and medicinal purposes.

This initial Phase 1 study is to be conducted as an open label, dose-ranging safety assessment of a single dose of SM-001 taken orally by healthy adult volunteers. Twelve adult men and women, ages 25-65 years, will be consecutively assigned to one of three dose levels, 4 subjects per group (2 M; 2 F). In the presence of the Clinical Investigator(s), each subject will receive a single dose of SM-001, administered at the Clinical Study Site as a liquid at one of three dose levels: 0.25, 0.5, or1.5 ml SM-001 per kg body weight. To assess systemic exposure to SM-001, plasma levels of the four biomarkers, dimethyltryptamine, harmine, tetrahydroharmine, and harmaline will be measured. Blood samples will be drawn at baseline, HR 0 (pre-Study Drug dose), and then at HR 1, 2, 4, 8, and 24 post dose. Subjects will return to the Clinical Study Site at Study Day 28 for a final in-person assessment.

What is being measured

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

  1. Primary Objective

    To evaluate safety and tolerability of SM-001 in healthy adults following a single oral dose, at one of three different dose levels. The Incidence of Treatment-Emergent Adverse Events will be assessed using the Common Terminology Criteria for Adverse Events (CTCAE).

    Percentage of participants with at least one safety event [Time Frame: Baseline up to Day 28 ] Safety will be evaluated by the monitoring of adverse events (AEs), vital signs, blood pressure, heart rate, pulse oximetry, electrocardiogram (ECG) evaluations, clinical laboratory assessments and physical examination findings.

    Measured: 1-28 days

Secondary outcomes (5)
  1. Short-term psychological impact

    To assess short-term psychological impact of a single dose of SM-001 at three different dose levels in healthy adults by asking each study subject to complete a questionnaire called the Hallucinogenic Rating Scale 24 hours after the single experimental drug session. This is an 85 item questionnaire with each item rated 0-4 with a maximum score of 340. A higher score correlates with a more intense psychological experience.

    Measured: 24 hours after single drug session

  2. Longer-term psychological impact

    To assess longer-term psychological impact of a single dose of SM-001 at three different dose levels in healthy adults by asking each study subject to complete a questionnaire called the Persisting Effects Questionnaire 7 days following the single experimental drug session.

    The Persisting Effects Questionnaire includes 140 of the items that are rated on a 6-point scale (0=none, not at all; 1=so slight cannot decide; 2=slight; 3=moderate; 4=strong; 5=extreme, more than ever before in your life and stronger than 4).

    Measured: Day 7 after a single drug session

  3. Bioavailability of SM-001

    To determine the blood, urine and feces levels of plant alkaloids including dimethyltryptamine, harmine, tetrahydroharmine and harmaline in ng/mL following a single oral dose of SM-001.

    Measured: Day 1-2

  4. Effects of a single dose of SM-001 on blood levels of brain derived nerve growth factor

    Brain Derived Neurotrophic Factor will be quantitated (ng/mL) is each study subject's blood on the day before and the day after the SM-001 drug session.

    Measured: Day 1-28

  5. Effects of a single dose of SM-001 on blood cortisol blood levels

    Cortisol levels in each study subject's blood will be measured (mg/mL)

    Measured: Day 1 - 28

Model description
Subjects will be consecutively accrued to one of three study groups, starting at the lowest dose, Level 1 ("low" dose), and proceeding to the next higher dose level. Each subject will receive one dose of the Study Drug orally at the Clinical Study Site, according to their assigned dose Level. Dose levels vary by volume: Level 1: 0.5 mL/kg ("low"; 50% of usual dose) N=4 (2M/2F) Level 2: 1 ml/kg ("medium"; 100% of usual dose) N=4 (2M/2F) Level 3: 2 ml/kg ("high"; 200% of usual dose) N=4 (2M/2F)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SM-001 in people with Major Depression and Post Traumatic Stress Disorder, run by Advanced Integrative Medical Science Institute 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 7 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 7 Jul 2023. 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 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 Leanna J Standish, ND PhD (2064201321, Lstandish@aimsinstitute.net), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Objective (time frame: 1-28 days). 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 NCT05894902, which also lists 36 linked publications.

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 7 Jul 2023.
