E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The principal research question/objective is to determine whether Losartan, taken as a tablet (50mg once a day) versus a dummy pill (which will look exactly the same as the real medication) is effective at slowing down, halting or reversing liver fibrosis (scar tissue) in patients with non-alcoholic steatohepatitis. |
|
E.2.2 | Secondary objectives of the trial |
The secondary research questions/objectives are: 1. to determine whether Losartan can prevent clinical deterioration in NASH, or impact on the quality of life. 2. to show any changes in serum (blood sample), radiological (fibroscan) or histological (liver tissue) samples giving an indication to disease progression. 3. to measure the change in non-alcoholic fatty liver disease (NAFLD) activity score (NAS) from baseline. 4. to note responder rate for placebo versus intervention. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Inclusion criteria: Adults (aged 18+ years), with steatohepatitis and fibrosis (Kleiner F1-F3), resulting from non-alcoholic fatty liver disease. |

Exclusion criteria: 1. refusal or inability (lack of capacity) to give informed consent 2. average alcohol ingestion more than 21 units per week (males) or more than 14 units per week (females) 3. history or presence of Type 1 diabetes mellitus 4. haemoglobin A1C >15.0 5. other causes of chronic liver disease or hepatic steatosis 6. any contra-indication to liver biopsy 7. history of or planned gastrointestinal bypass surgery 8. hepatocellular carcinoma 9. previous liver transplant 10. recent significant weight loss (more than 5% total body weight within last 6 months) 11. electrolyte disturbance: potassium level outside the normal (local) range. 12. ALT or AST > 10 x ULN at screening 13. recent (within six months of baseline liver biopsy and screening visit) or concomitant use of agent known to cause hepatic steatosis (corticosteroids, amiodarone, methotrexate, tamoxifen, tetracycline, high dose oestrogens, valproic acid), or concomitant use of pioglitazone, fluconazole, rifampicin or any drug contra-indicated in the Losartan Summary of Product Characteristics (SmPC) 14. Introduction of metformin, glitazones, a GLP-1 agonist, Vitamin E or C, betaine, s-adenosyl methionine, ursedeoxycholic acid, silymarin, fibrate, pentoxifylline, orlistat, sibutramine or rimonabant within 3 months of baseline liver biopsy and screening visit. 15. intolerance of ARBs or presence of multiple allergic reactions to drugs 16. use of ACE inhibitor or ARB in previous year 17. hypotension (Systolic less than 100, diastolic less than 60) 18. renal failure (Cr >130) 19. participation in any clinical study of an investigational medicinal product (IMP) within 30 days or five half-lives of the IMP, whichever is longer 20. presence of clinically relevant cardiovascular, pulmonary, gastro-intestinal, renal, hepatic, metabolic, haematological, neurological, psychiatric, systemic, ocular, gynaecological or any acute infectious disease or signs of acute illness that, in the opinion of the investigator, might compromise the patient’s safe participation in the trial 21. presence or history of cancer within the past five years, with exception of adequately-treated localised basal cell carcinoma of the skin, in situ cervical carcinoma or solid malignancy surgically excised in toto without recurrence for five years 22. women of child-bearing potential not protected by effective contraceptive method of birth control or surgical sterilization, and/or who are unwilling or unable to be tested for pregnancy (Pregnancy status will be checked by serum pregnancy testing before initiation of study treatment and by urine pregnancy testing during the trial) 23. known allergy or sensitivity to Losartan or its excipients (microcrystalline cellulose (E460); lactose monohydrate; pregelatinized maize starch; magnesium stearate (E572); hydroxypropyl cellulose (E463); hypromellose (E464)) |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome will be change in Kleiner fibrosis score, [Kleiner DE et al, Hepatology 2005], based on histological fibrosis stage (as judged by two independent blinded histopathologists, from liver biopsies), from pre-treatment to end-of-study (ie. 96 weeks follow-up). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
This endpoint measured at visit 8 (96 weeks). |
|
E.5.2 | Secondary end point(s) |
Secondary outcomes are: changes in radiological (Fibroscan) assessment. changes in serological (Enhanced Liver Fibrosis - ELF and Fibromax). change in non-alcoholic fatty liver disease (NAFLD) activity score (NAS) - determined by liver biopsy. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
This endpoint measured at visit 1 (screening), 48 & 96 weeks. NAS (liver biopsy) measured prior to study entry and at 96 weeks. |
