Study information

Scientific title

A 48-week pahse II, randomised, double blinded placebo controlled, parallel-group, multicentre trial on liraglutide's safety, efficacy and action on liver histology and metabolism in overweight patients with non-alcoholic steatohepatitis, with or without type II diabetes



Study hypothesis

Non-alcoholic fatty liver disease (NAFLD) is responsible for an increasing prevalence of liver disease and is becoming the commonest cause of liver disease in the western world. NAFLD is recognised to be the hepatic manifestation of the metabolic syndrome, which is a cluster of metabolic abnormalities characterised by abdominal obesity, insulin resistance, impaired glucose metabolism, hypertension and dyslipidaemia. In its mildest form there is an accumulation of fat in the liver (steatosis) without any liver damage, however in many cases it progresses to non-alcoholic steatohepatitis (NASH), and cirrhosis.

Current treatment options for NASH are limited in efficacy, necessitating the development of more effective options. New agents such as Glucagon-like Peptide-1 (GLP-1) agonists that improve diabetic control and facilitate weight loss have been suggested as therapies in NASH.

No published studies to date have assessed the impact of the GLP-1 agonist, Liraglutide, on liver histology and metabolism in obese patients with NASH. This study hypothesises that treatment with liraglutide will result in a significant improvement in histological disease activity in obese patients with NASH, in the presence or absence of Type 2 Diabetes (T2DM).

The primary objective is to investigate whether 48 weeks treatment with once-daily injections of liraglutide improves liver histology in overweight patients with NASH enough to warrant further investigation.

The secondary objectives are to investigate whether 48 weeks treatment with once-daily injections of liraglutide in overweight patients with NASH results in a clinically significant effect on the:
1. Individual histological features of NASH including steatosis, hepatocyte inflammation and injury, and fibrosis.
2. Non-invasive clinical markers of steatosis, steatohepatitis and fibrosis.
3. Clinical components of metabolic syndrome
4. Insulin resistance and hepatic lipogenesis
5. Patients Quality of Life (QOL)
6. Clinical safety profile

Non-alcoholic Steatohepatitis (NASH)


Please note that as of 14/08/10 this Birmingham, UK site is open/active to recruitment.

1. Placebo/Control Group:
Treatment with once-daily subcutaneous injection of inactive placebo-control (i.e. identical to experiment drug minus the active substance liraglutide - Supplied by Novo Nordisk ®) for 48 weeks.
2. Interverntion group:
Treatment with once-daily subcutaneous injections 1.8mg active Liraglutide (Victoza) (Supplied by Novo Nordisk ®) for 48 weeks.
Group 1 and 2 will contain the same proportion of non-diabetics and Type II diabetics, and the same proportion of patients enrolled from UK and Germany.
Participants will attend two screening visits in the first two weeks. Then if eligible will commence study treatment for 48 weeks (336 days), during which time they will be asked to attend 5 study visits. A follow up visit will take place 24 weeks after completion of 48 weeks study treatment. Therefore the estimated duration of the study is 74 weeks from screening to end of follow up.

Primary outcome measure

The primary outcome measure is the proportion of patients with an improvement in liver histology after 48-weeks of treatment as defined by;

6. Glycaemic control (HbA1c, Fasting plasma glucose [central laboratory], fasting self-measured plasma glucose [SMPG]), assessed at baseline, 4, 12, 24, 36, 48 weeks and follow-up
7. Serological markers of insulin sensitivity and lipid profile, assessed at baseline, 12, 24, 26 and 48 weeks
8. Total body, hepatic, muscle, and adipose insulin sensitivity using hyperinsulinaemic euglycaemic and adipose microdialysis studies, assessed at baseline (screening) and 12 weeks
9. De-novo hepatic lipogensis (DNL) using stable isotope experiments, assessed at baseline (screening) and 12 weeks
10. Quality of life (SF-36v2) and Nutrition (Block Brief 2000 FFQ) questionnaires, assessed at baseline (screening), 48 weeks and follow-up
11. Safety measures (History and clinical examination, hypoglycaemia rates, routine bloods tests, TFTs and calcitonin, insulin detemir [Levemir®] and liraglutide [Victoza®] antibodies), assessed at baseline, 4, 12, 24, 36, 48 weeks and follow-up
