Clinical Trial Summary

The R61 will include two CBD dose levels vs placebo (PBO) and examine potential engagement with two primary targets in a 3-week randomized controlled trial design. Willing and eligible subjects will be randomized to one of three randomized double-blind treatments (n = 20 each group): 1) CBD 800 mg (400 mg twice daily), 2) CBD 400 mg (200 mg twice daily), or 3) PBO twice daily for three weeks. Participation is estimated at approximately 1 month from end of screening to endpoint for the primary R61 study period. This includes screening, baseline, week 2 stress task, Week 3 2-day imaging paradigm, and clinical safety assessments at weeks 2 and 3.


Clinical Trial Description

In the R61 trial, two doses of a Phase 3 trial suitable hemp-derived (legal) oral CBD formulation with enhanced bioavailability will be compared against placebo (PBO) in a 3-week double-blind randomized controlled trial. Participants will undergo a standardized stress task at week 2, and a standardized 2-day fear learning and extinction protocol at week 3, with functional MRI (fMRI) brain activation accompanying fear extinction recall and fearful faces tasks on the second day. ;
