Generalized Anxiety Disorder study: Low-Dose Cannabidiol vs Moderate-Dose Cannabidiol
Official title Cannabidiol-Assisted Learning for Managing Generalized Anxiety Disorder
ClinicalTrials.gov ID: NCT07123467
What this study is testing
What is Low-Dose Cannabidiol?
This is an investigational oral liquid medicine being studied to see if it helps with generalized anxiety disorder when used with therapy. It is designed to help the brain manage emotions by affecting specific areas involved in emotion regulation.
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
- The study wants to see whether taking cannabidiol with cognitive behavioral therapy improves anxiety symptoms and helps the brain regulate emotions better than therapy with a placebo.
- Who it's for
- Adults who have generalized anxiety disorder and are willing to try therapy and medication.
- What's involved
- Participants will receive either cannabidiol or a placebo while attending regular therapy sessions and will have brain scans and symptom questionnaires done.
- Time commitment
- The study lasts several weeks, with multiple therapy visits, medication doses, and brain scan appointments scheduled throughout the trial.
- 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.
