Brief Summary

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

Condition or Disease	Intervention/Treatment	Phase
Major Depression Post Traumatic Stress Disorder	Drug: SM-001	Phase 1

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: 1, 2, or 3 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.

Interventional

Anticipated Enrollment :

12 participants

Allocation:

Randomized

Intervention Model:

Sequential Assignment

Intervention 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)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.

Outcome Measures

Primary Outcome Measures

Primary Objective [1-28 days]
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.

Secondary Outcome Measures

Short-term psychological impact [24 hours after single drug session]
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.
Longer-term psychological impact [Day 7 after a single drug session]
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).
Bioavailability of SM-001 [Day 1-2]
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.
Effects of a single dose of SM-001 on blood levels of brain derived nerve growth factor [Day 1-28]
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.
Effects of a single dose of SM-001 on blood cortisol blood levels [Day 1 - 28]
Cortisol levels in each study subject's blood will be measured (mg/mL)
