A Pharmacokinetic Study to Compare CBD-NE to Epidyolex in Healthy Adult Volunteers Under Both Fed and Fasted Conditions
Summary
Cannabidiol (CBD), derived from the Cannabis sativa plant, is being investigated for its potential health benefit without the psychoactive properties and adverse reactions that arise from the use of delta-9-tetrahydrocannabinol (Δ9-THC). Few studies have characterized the pharmacokinetic (PK) effects and safety of oral CBD administration. Epidiolex (Epidyolex), an oil form of CBD, is the only marketed monotherapy approved by the United States Food and Drug Administration (FDA) and Health Canada. Delivery of a CBD in a powder/capsule form may provide a more efficient method for consumers. The goal of this study is to characterize the PK profile of the test product, CBD-NE (a capsule formulation) compared to Epidyolex under both fasted and fed conditions. Each participant will receive a dose of each product under both fed and fasted conditions in a crossover design.
