Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Cannabidiol extract
10 healthy subjects (5 female, 5 male), will be enrolled into the study. Each subject will receive a single CBDE dose delivering 2.5 mg/kg CBD, after consumption of a standardized meal.
Nine (9mL) of blood for PK analysis, at each of the following timepoints: 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 8 hours, 12 hours, 24 hours, 36 hours, 48 hours and 72 hours after the study drug administration.
Urine will be collected at the following timepoints: Predose, 0-4 hrs, 4-8 hrs, 8-12 hrs, 12-24 hrs, 24-36 hrs, 36-48 hrs, and 48-72 hrs for PK analysis
cannabidiol extract
The test article "CBD Cannabis Extract Oral Solution" will be manufactured by the University of Mississippi National Center for Natural Products Research (NCNPR) at the Coy Waller Laboratory under FDA Current Good Manufacturing Practices. The drug product, derived from hemp and containing less than 0.3% of Δ9-tetrahydrocannabinol, is no longer a Drug Enforcement Agency (DEA) controlled substance. DEA registrations are not required for the manufacturing, handling or dispensing of these clinical test materials
