Participant Flow

Participants were recruited from a pool of participants who previously participated in studies at the UC San Diego HNRP-CMCR and were willing to be contacted about future studies. The first participant was screened in November 2023.

Adult participants with HIV are randomized to receive Placebo or CBD (a liquid solution of CBD made from semi synthetic CBD powder) for 6 weeks.

Participant milestones
Measure
Synthetic CBD 4-Week Trial Arm
For one week they will titrate up to the maintenance dose of 600 mg/day of Purysis, a synthetic, liquid form of CBD, which they will continue for 4 weeks. Upon completion of the 4-week trial, they will be re-assessed, followed by one week of titrating down to discontinuation.
Placebo 4-Week Trial Arm
For one week they will titrate up to the maintenance dose of 600 mg/day of placebo for Purysis, a synthetic, liquid form of CBD, which they will continue for 4 weeks. Upon completion of the 4-week trial, they will be re-assessed, followed by one week of titrating down to discontinuation.
