Clinical Trial Summary

We will study whether cannabidiol (CBD), the primary centrally and peripherally active non-intoxicating compound in the cannabis plant, exerts anti-neuroinflammatory effects in patients with chronic low back pain (cLBP) with or without mild-to-moderate depression.


Clinical Trial Description

We will conduct a randomized, double-blind, 2-arm mechanistic trial to assess the effects of CBD and placebo in patients with cLBP with and without mild-to-moderate depression, using integrated positron emission tomography / magnetic resonance imaging (PET/MRI) scans. The use of integrated PET/MRI will allow us to simultaneously evaluate neuroinflammation (using [11C]PBR28, a second-generation radioligand for TSPO) and striatal function (using the Monetary Incentive Delay task, a validated fMRI task that probes behavioral and neural responses to rewards and losses). ;
