简要总结
The purpose of this study is to evaluate the effect of GWP42003 on liver triglyceride (liver fat) in participants with fatty liver disease (FLD).
详细描述
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.

盲法说明
This study was partially-blinded. Due to the varying numbers of capsules administered, participants and investigators were not blinded to the treatment cohort (one, two or four capsules), but were blinded to the treatment allocation within each cohort (GWP42003 or placebo)

研究组 & 干预措施
GWP42003 200 milligrams (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]).
干预措施: GWP42003 200 mg/day Dose (Drug)
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]).
干预措施: GWP42003 400 mg/day Dose (Drug)
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]).
干预措施: GWP42003 800 mg/day Dose (Drug)
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]).

结局指标
主要结局
Percent Change From Baseline To The End Of Treatment (EOT) In Mean Liver Triglyceride Levels
时间窗: 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.
次要结局
- Change From Baseline To The EOT In Mean Serum Total Cholesterol Levels(Baseline to EOT (Day 57) or ET)
- Change From Baseline To The EOT In Mean Serum Low-Density Lipoprotein (LDL)-C Levels(Baseline to EOT (Day 57) or ET)
- Change From Baseline To The EOT In Mean Serum High Density Lipoprotein (HDL)-Cholesterol(C) Levels(Baseline to EOT (Day 57) or ET)
- Change From Baseline To The EOT In Mean Serum HDL: Low Density Lipoprotein (LDL)-Cholesterol (C) Ratio(Baseline to EOT (Day 57) or ET)
- Change From Baseline To The EOT In Mean Serum Triglyceride Levels(Baseline to EOT (Day 57) or ET)
