Recruiting PHASE3 Generalized Anxiety Disorder (GAD)

New treatment option for Generalized Anxiety Disorder (GAD)

Official title Cannabidiol-Assisted Learning for Managing Generalized Anxiety Disorder

ClinicalTrials.gov ID: NCT07123467

What this study is testing

What is Low-Dose Cannabidiol?

Low-Dose Cannabidiol is an investigational medicine, given as a pill taken by mouth, being studied as a potential treatment for generalized anxiety disorder (gad).

Also referred to as EPIDIOLEX®.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This randomized, double-blind, placebo-controlled clinical trial investigates the use of Food and Drug Administration (FDA)-approved cannabidiol (EPIDIOLEX®) as an adjunct to cognitive behavioral therapy (CBT) in adults with generalized anxiety disorder (GAD). The study aims to evaluate whether cannabidiol-assisted CBT enhances emotion regulation via dorsomedial prefrontal cortex (dmPFC) activation and improves anxiety symptom outcomes compared to CBT with placebo.
  • Phase 3: a large, late-stage study
  • You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
