Determination of Cannabinoid and Cannabinoid Metabolite Levels in Healthy Volunteers

Levels of major cannabinoid and cannabinoid metabolites (i.e., CBD, CBD-OH) will be determined in the plasma of healthy volunteers following 10 days of Happy Lane Hemp Extract/CBD soft gels (25 mg per capsule) supplementation using liquid chromatography-mass spectrometry (LCMS).

Study Overview

• Status: Withdrawn
• Conditions: Healthy
• Intervention / Treatment: Dietary supplement: Happy Lane Hemp Extract/CBD soft gels (25 mg/capsule)

Detailed Description

The objective of the study is to determine the levels of CBD, CBD-OH, THC, THC-COOH, and 11-OH-THC in plasma of healthy volunteers that have ingested hemp extract/CBD for 10 consecutive days.

The research team is planning to recruit 24 adults (12 females, 12 males), age of 18-45 years old, inclusive to allow for enrollment of 20 eligible adults (10 females, 10 males). Subjects will be identified and recruited using AR Research via the UAMS Translational Research Institute (TRI). Specifically, TRI coordinators will assist with calling, screening, and scheduling potential subjects based on the list generated from AR Research.

After signing the informed consent form, which includes an attestation that the subject has not used cannabinoids within the past 4 weeks and an attestation that the subject will not use any prescription or over-the-counter medications during the study, each subject will provide a baseline plasma sample (up to 15 mL, collected by TRI coordinators) that will be used to determine if any cannabinoids (CBD, CBD-OH, THC, THC-COOH, and 11-OH-THC) are present in the blood.

All blood samples (pre- and post-intervention) will be analyzed at the completion of the study. Therefore, if cannabinoids are found in any of the baseline samples, the result will be noted but will not necessarily result in any subjects being excluded from the study. However, exclusion of data from subjects whose initial test show a positive result for CBD or THC from the overall study may be deemed necessary by the research team under certain circumstances (e.g., if the baseline THC and/or CBD signal in a study subject is so large that accurate detection of the intervention would be hindered).

After the informed consent form is signed and the baseline plasma sample is drawn, each subject will be provided with Happy Lane™ Hemp Extract/CBD soft gels (25 mg CBD per capsule; the certificate of analyses is provided along with this Study Protocol). Half of the subjects (5 women and 5 men) will be taking one gel capsule per day (25 mg/day dose), while the other half (5 women and 5 men) will be taking 2 gel capsules per day (50 mg/day dose, both capsules will be taken at the same time). Group assignment will be made randomly based on a computer-generated randomization list.

Subjects will take gel capsules for 10 consecutive days at approximately the same time of day (±1 hour) on each of these days, beginning the morning after consent is provided (Day 2). During this 10-day period, subjects will record number of capsules (1 or 2) and time of day ingested, as well as any adverse event in a diary. This diary will be provided to each subject at the time of consent (Day 1), and each subject will return for a second visit within 2 to 6 hours after the last dose of the 10-day regimen (Day 11). During the second visit, subject will return to TRI, and a blood specimen (up to 15 mL) will be collected. Diaries, empty capsule bottles, and any extra/unused capsules will also be returned to the study staff during this second visit (Day 11), so that capsule count may be conducted by study staff for drug accountability. Subjects will receive a follow-up phone call (Day 13 or next business day) to collect any adverse events (AE) that occurred after diaries were returned.

The blood specimens will be used for determination of major cannabinoids using the liquid chromatography-mass spectrometry. The cannabinoid/metabolite analysis will be performed at a certified laboratory in Oxford, Mississippi - ElSohly Laboratories, Inc (http://www.elsohly.com/). This is a DEA licensed analytical laboratory under leadership of Dr. Mahmoud ElSohly.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: 25 mg/day dose of Happy Lane CBD (Lower Dose); One 25 mg Happy Lane CBD gel capsule per day (25 mg/day total dose) for 10 consecutive days at approximately the same time of day (±1 hour) on each of these days.	Dietary supplement: Happy Lane Hemp Extract/CBD soft gels (25 mg/capsule); Half of the study participants (5 women and 5 men) will be taking one gel capsule per day (25 mg/day dose), while the other half (5 women and 5 men) will be taking 2 gel capsules per day (50 mg/day dose). Study participants will be taking gel capsules for 10 consecutive days. At the end of this 10-day regimen, study participant will return to the TRI where blood specimen (up to 15 mL) will be collected within 2 to 6 hours after the last dose.
