Pharmacokinetics and Pharmacodynamics of CHI-914 in Healthy Participants

The purpose of the present study is to examine the pharmacokinetics and pharmacodynamics of cannabigerol (CBG; CHI-914), a naturally occurring chemical constituent of the cannabis plant formulated for oral consumption, in healthy adults. The study will utilize a within-subjects, placebo-controlled, double-blind, ascending-dose design. Oral drug administration will be double blind (the participant and research staff will be unaware of the dose administered; though active doses will be fixed in ascending order, placebo will be randomly assigned). Upon enrollment, participants will complete 5 oral dosing conditions (placebo, 25, 50, 100, and 200 mg CBG). Doses were selected based on current retail CBG products and web-based surveys of CBG use among current CBG product users. Each condition will consist of a single acute drug exposure, followed by an 8-hour period to evaluate acute pharmacodynamic and pharmacokinetic drug effects. Blood specimens will be obtained throughout these 8 hours to characterize the pharmacokinetics of CBG. Pharmacodynamic assessments including subjective drug effects, cognitive performance testing, and vital signs will also be collected for 8 hours post-drug administration. Experimental test sessions will be separated by at least 1 week to allow for sufficient drug washout between doses. This work will provide novel data on the pharmacokinetics, pharmacodynamic effects, and safety of acute oral CBG dose administration in humans.
