Role of CBD in Regulating Meal Time Anxiety in Anorexia Nervosa
March 2, 2024 updated by: Guido Frank, University of California, San Diego
The Role of Cannabidiol in Regulating Meal Time Anxiety in Anorexia Nervous: Safety, Tolerability and Pharmacokinetics
No studies of cannabidiol (CBD) have focused on Anorexia Nervosa (AN).
Dose, side effects, tolerability, acceptability of pure CBD in AN must be established.
The current study is an important first step in the investigation of CBD for AN.
Cannabis products have been recently legalized in many states, and CBD in particular has been shown to reduce anxiety.
Therefore, CBD may represent a promising new treatment for AN.
The endocannabinoid system is involved in the regulation of functions relevant to eating disorders.
Furthermore, data suggest that eating disorders are associated with alterations of the endocannabinoid system.
Prior attempts to target the endocannabinoid system in AN have focused on CB1 receptor agonists that can increase anxiety.
Moreover, CBD may be particularly beneficial in decreasing anxiety in AN via its action at serotonin receptors.
Lastly, the impact of CBD on eating behavior and weight in AN must be determined.
The current study seeks to explore these hypotheses using the aims in the following section.

Experimental: Cannabidiol (CBD)
Days 1 to 7: Patients will receive CBD 2.5 mg/kg in divided doses BID for 7 days. Days 8 to 14: Patients will receive an increase dose of 7.5 mg/kg of CBD in divided doses. Days 15 to 21: Patients will receive an increased dose of 12.5 mg/kg CBD, in divided doses. If patients experience dose limiting side-effects, they ill be maintained on the lowest tolerated dose. |

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Committee of Clinical Investigations UKU-Side Effect Scale Week 1
Time Frame: After completion of Week 1 of treatment
|
The Committee of Clinical Investigations (UKU) scale is used to rate psychiatric (e.g., depression, failing memory, concentration difficulty), neurological (e.g., rigidity, tremor, epileptic seizure), and autonomic (e.g., nausea, diarrhea, tachycardia) side effects, plus others.
Higher scores indicate more side effects.
|
After completion of Week 1 of treatment
|
Committee of Clinical Investigations UKU-Side Effect Scale Week 2
Time Frame: After completion of Week 2 of treatment
|
The Committee of Clinical Investigations (UKU) scale is used to rate psychiatric (e.g., depression, failing memory, concentration difficulty), neurological (e.g., rigidity, tremor, epileptic seizure), and autonomic (e.g., nausea, diarrhea, tachycardia) side effects, plus others.
Higher scores indicate more side effects.
|
After completion of Week 2 of treatment
|
Committee of Clinical Investigations UKU-Side Effect Scale Week 3
Time Frame: After completion of Week 3 of treatment
|
The Committee of Clinical Investigations (UKU) scale is used to rate psychiatric (e.g., depression, failing memory, concentration difficulty), neurological (e.g., rigidity, tremor, epileptic seizure), and autonomic (e.g., nausea, diarrhea, tachycardia) side effects, plus others.
Higher scores indicate more side effects.
|
After completion of Week 3 of treatment
|
Blood tests for cannabinol (CBD) metabolites Week 1
Time Frame: After Completion of Week 1 of treatment
|
Blood levels for CBD, 6-OH-CBD, 7COOH-CBD, THC.
The results will be compared to standard laboratory values.
|
After Completion of Week 1 of treatment
|
Blood tests for cannabinol (CBD) metabolites Week 2
Time Frame: After completion of Week 2 of treatment
|
Blood levels for CBD, 6-OH-CBD, 7COOH-CBD, THC.
The results will be compared to standard laboratory values.
|

|
Change from baseline scores of Eating Disorder Examination Questionnaire (EDE-Q) over the course of treatment
Time Frame: Weekly for the duration of the project (three weeks)
|
Assesses the change from baseline in BMI, Eating Restraint, Eating Concern, Shape Concern, Weight Concern over the course of treatment.
Each of those subscales is rated between 0 and 5. Subscales are calculated based on the average scores for the respective subscale.
Higher scores indicate poorer outcome.
