NCT06393101

Brief Summary

The aim of this trial is to determine the potential effects and mechanisms of cannabinoid-induced pain relief in complex regional pain syndrome (CRPS). Multiple psychophysical approaches will be conducted in conjunction with psychological and inflammatory marker testing to determine if and how cannabinoids produce stabilized improvement in CRPS-related pain and comorbidities. The trial consisted of a pre-treatment screening period, six-week treatment period and a two-week follow-up.

Placebo Comparator: 1 Placebo

PLACEBO COMPARATOR

Half of the patients will receive PO placebo

Drug: BRC-002 Placebo

Experimental: Active

EXPERIMENTAL

Drug: BRC-002 (High Cannabidiol Botanical Extract) 100 mg/mL

Drug: BRC-002

Interventions

BRC-002 is a non-scheduled cannabidiolic (CBD) formulation (\<.3% THC). The cannabinoids in BRC-002 are naturally biosynthesized within the Cannabis sativa L. plant as acidic forms of CBD (cannabidiolic acid; CBDA), THC (tetrahydrocannabinolic acid; THCA) and other minor cannabinoids.

Experimental: Active

Oral solution of mono-, di-, and triglycerides
