Phase 2

Completed

Conditions: Fatty Liver

Interventions: Drug: GWP42003 800 mg/day Dose
Drug: GWP42003 400 mg/day Dose
Drug: Placebo
Drug: GWP42003 200 mg/day Dose

Registration Number: NCT01284634

Lead Sponsor: GW Research Ltd

Brief Summary: The purpose of this study is to evaluate the effect of GWP42003 on liver triglyceride (liver fat) in participants with fatty liver disease (FLD).

Detailed Description: This study was conducted as a 10-week (eight-week treatment period and one-week safety follow-up), randomized, partially-blind study that evaluated the effect of GWP42003 in participants with raised liver triglycerides (liver fat ≥5%). Participants were clinically diagnosed with FLD and had liver fat levels ≥5% as measured by Magnetic Resonance Imaging/ Magnetic Resonance Scanning (MRI/MRS), or were willing to undergo MRI/MRS scan at the screening visit to confirm a liver fat content of ≥5%. Eligible participants entered the study at a screening visit (Day -10 to -2) and then returned for a fasted baseline visit (Day 1), a mid-treatment visit (Day 29) and an end of treatment visit (Day 57). Safety follow-up telephone calls took place throughout the treatment period up to Day 64 after completion of treatment or seven days after date of last dose/withdrawal.

Arm && Interventions

Group	Intervention	Description
GWP42003 800 mg/day Dose	GWP42003 800 mg/day Dose	Participants self-administered four x 100 mg GWP42003 capsules twice daily for 8 weeks (the first dose was 30 minutes before breakfast \[fasted\] and the second was 30 minutes before the evening meal \[typically 12 hours apart\]).
GWP42003 400 mg/day Dose	GWP42003 400 mg/day Dose	Participants self-administered two x 100 mg GWP42003 capsules twice daily for 8 weeks (the first dose was 30 minutes before breakfast \[fasted\] and the second was 30 minutes before the evening meal \[typically 12 hours apart\]).
Placebo	Placebo	Participants self-administered one, two or four placebo capsules twice daily, for 8 weeks (the first dose was 30 minutes before breakfast \[fasted\] and the second was 30 minutes before the evening meal \[typically 12 hours apart\]). Each capsule exactly matched the GWP42003 capsules in terms of appearance, size, smell and taste.
GWP42003 200 milligrams (mg)/day Dose	GWP42003 200 mg/day Dose	Participants self-administered one x 100 mg GWP42003 capsule twice daily for 8 weeks (the first dose was 30 minutes before breakfast \[fasted\] and the second was 30 minutes before the evening meal \[typically 12 hours apart\]).

Primary Outcome Measures

Name	Time	Method
Percent Change From Baseline To The End Of Treatment (EOT) In Mean Liver Triglyceride Levels	Baseline to EOT (Day 57) or Early Termination (ET)	Liver triglyceride levels were measured by Magnetic Resonance Imaging/Magnetic Resonance Scanning and the percent change from baseline to EOT in group mean levels was investigated. A reduction from baseline, that is, a negative value, indicates an improvement in condition.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline To The EOT In Mean Serum Total Cholesterol Levels	Baseline to EOT (Day 57) or ET	A fasting blood sample was taken for the measurement of serum total cholesterol. A reduction from baseline, that is, a negative value, indicates an improvement in condition.
Change From Baseline To The EOT In Mean Serum Low-Density Lipoprotein (LDL)-C Levels	Baseline to EOT (Day 57) or ET	A fasting blood sample was obtained for the measurement of LDL-C. An increase from baseline, that is, a positive value, indicates an improvement in condition.
Change From Baseline To The EOT In Mean Serum High Density Lipoprotein (HDL)-Cholesterol(C) Levels	Baseline to EOT (Day 57) or ET	A fasting blood sample was obtained for the measurement of HDL-C. An increase from baseline, that is, a positive value, indicates an improvement in condition.
Change From Baseline To The EOT In Mean Serum HDL: Low Density Lipoprotein (LDL)-Cholesterol (C) Ratio	Baseline to EOT (Day 57) or ET	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, that is, a positive value, indicates an improvement in condition.
Change From Baseline To The EOT In Mean Serum Triglyceride Levels	Baseline to EOT (Day 57) or ET	A fasting blood sample was obtained for the measurement of serum triglycerides. A reduction from baseline, that is, a negative value, indicates an improvement in condition.
