Official Title: A Randomised, Partially-blind, Placebo-controlled, Pilot, Dose-ranging Study to Assess the Effect of Cannabidiol on Liver Fat Levels in Subjects With Fatty Liver Disease

Brief Summary: The purpose of this study is to assess the effect of cannabidiol (CBD) on liver triglyceride (liver fat) in subjects with fatty liver disease.

Detailed Summary:

This 10 week (2-10 day screening, eight week treatment period and one week follow-up), randomized, partially-blind study will assess the effect of CBD in subjects with raised liver triglycerides (liver fat ≥ 5%).

Eligible subjects will enter the study at a Screening Visit (Visit 1, Day -10 to -2) and commence a two to ten day screening period, before returning for a baseline visit (Visit 2, Day 1).

During the fasted Screening Visit, study-related observations will include: informed consent, demographics, medical history, physical examination, electrocardiogram (ECG), vital signs, weight, height and concomitant medications.

Subjects will have the following assessments performed:

  1. Fasting lipid profile blood sample
  2. Fasting plasma glucose, HbA1c & fasting serum insulin
  3. Safety blood tests (haematology and biochemistry)
  4. Urinalysis (including drugs of abuse screen)
  5. CAGE Questionnaire to assess alcohol dependency
  6. Body weight will be measured and BMI calculated
  7. Pregnancy test (if appropriate)
  8. Liver triglyceride content (Magnetic Resonance Spectroscopy (MRS)) scan unless there is documented history of a liver fat content equal to or above 5% as measured by Magnetic Resonance Imaging (MRI)/MRS or a biopsy within the last two months prior to this screening visit. Where subjects (and/or carers) feel the scan poses a significant burden (in addition to the other visit procedures), the fasted scan may be undertaken separately with the remaining visit procedur

    Current Primary Outcome: Change From Baseline to the End of Treatment in Mean % Liver Triglyceride Levels [ Time Frame: After 56 days of treatment ]

    Liver triglyceride levels (%) were measured by MRI/MRS scanning and the change from baseline to end of treatment in group mean levels were investigated. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.


    Original Primary Outcome: Liver triglyceride levels in subjects with fatty liver [ Time Frame: Following 56 days of treatment ]

    Relationship between liver triglyceride levels and dose of cannabidiol will be explored graphically.


    Current Secondary Outcome:

    • Change From Baseline to the End of Treatment it Mean Serum Total Cholesterol Levels [ Time Frame: After 56 days of treatment ]
      A fasting blood sample was taken for the measurement of serum total cholesterol. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Serum High Density Lipoprotein (HDL)-Cholesterol(C) Levels [ Time Frame: After 56 days of treatment ]
      A fasting blood sample was obtained for the measurement of HDL-C. An increase from baseline (i.e. a positive value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Serum Low Density Lipoprotein (LDL)-Cholesterol(C) Levels [ Time Frame: After 56 days of treatment ]
      A fasting blood sample was obtained for the measurement of LDL-C. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment it the Mean Serum HDL:LDL Cholesterol Ratio [ Time Frame: After 56 days of treatment ]
      A fasting blood sample was obtained for the measurement of HDL-C and LDL-C, allowing the HDL:LDL cholesterol ratio to be calculated. An increase from baseline (i.e. a positive value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Serum Triglyceride Levels [ Time Frame: After 56 days of treatment ]
      A fasting blood sample was obtained for the measurement of serum triglycerides. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Fasting Plasma Glucose Levels [ Time Frame: After 56 days of treatment ]
      A fasting blood sample was obtained for the measurement of fasting plasma glucose. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Body Mass Index (BMI) [ Time Frame: After 56 days of treatment ]
      Individual subject's BMIs were calculated by dividing mass (kg) by height (m2). A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Body Weight [ Time Frame: After 56 days of treatment ]
      Body weight (kg) was measured at baseline and the end of treatment. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Waist-to-hip Ratio [ Time Frame: After 56 days of treatment ]
      The waist-to-hip ratio was calculated at baseline and the end of treatment. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Neck Measurement [ Time Frame: After 56 days of treatment ]
      The neck circumference was measured at baseline and the end of treatment. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Waist Measurement [ Time Frame: After 56 days of treatment ]
      Waist circumference was measured at baseline and the end of treatment. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Hip Measurement [ Time Frame: After 56 days of treatment ]
      Hip circumference was measured at baseline and the end of treatment. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Skin-fold Thickness (Chest/Pectoral) [ Time Frame: After 56 days of treatment ]
      Skin fold thickness measurements were the mean of three measurements per site calculated for each subject. If one or more measurements were missing for a site, then the mean was calculated over the available measurement(s) for that site. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Treatment in Mean Skin-fold Thickness (Midaxillary) [ Time Frame: After 56 days of treatment ]
      Skin fold thickness measurements were the mean of three measurements per site calculated for each subject. If one or more measurements were missing for a site, then the mean was calculated over the available measurement(s) for that site. A reduction from baseline (i.e. a negative value) indicates an improvement in condition.
    • Change From Baseline to the End of Tr
