Background and study aims
The build-up of fat in the liver can cause inflammation and a lot of scarring in the liver. This condition is called compensated cirrhosis due to non-alcoholic fatty liver disease (CC-NAFLD). It is a serious disease that may require liver transplant and increases the risk of early death. It affects about 200,000 UK adults, most of whom are also living with obesity.

Currently, there is no drug available to treat CC-NAFLD. Weight loss programmes might improve it, but only if they lead to large weight loss. One programme that could achieve this on a large scale is a low-energy diet with professional support. In this programme, people eat only soups and shakes for 16 weeks (about 860 calories per day). Then, slowly over the next 8 weeks, they swap some soups and shakes for regular food. The support helps people stick to the programme and develop healthier eating habits. We know people lose weight rapidly and lower their risk of heart disease. This may also be a good treatment for CC-NAFLD, but there is a concern that rapid weight loss may worsen scarring in the liver. Here we will test the programme in a small group of people with detailed monitoring of the health of their liver to see if this concern is a reality.
This information will tell us if we can confidently plan a full trial to test whether this programme can delay progression of this liver disease.

Who can participate?
Adults with CC-NAFLD and excess weight

What does the study involve?
A computer will decide at random if patients continue with their care as usual or are offered the programme. We will see whether enough patients are willing to take part in the trial, stick to the programme, and return for follow up visits. We will examine whether the treatment appears to be safe at 2, 4, 16, and 24 weeks with blood tests. If there are signs of worsening of the disease, we will stop the treatment. At the start of the programme and at 24 weeks, we will do a liver scan to make a more detailed assessment of liver scarring. We will also monitor changes in weight, body composition, risk of heart disease, and physical function.

What are the possible benefits and risks of participating?
There are no risks or benefits in the care as usual group. If there are signs of worsening of the disease in the intervention group, we will stop the treatment. Weight loss can also reduce the risk of heart disease and type 2 diabetes.

Scientific titleSafety signals and potential efficacy of a low-energy total diet replacement programme with behavioural support to delay disease progression in compensated cirrhosis due to non-alcoholic fatty liver disease: a feasibility randomised controlled trial
Study acronymLiFT 2
Study objectivesThis randomised controlled trial aims to examine whether people with compensated cirrhosis due to non-alcoholic fatty liver disease can be recruited, stick to the treatment, and present for follow-up, whether the treatment appears to be safe, and to look for early signs of attenuation of the progression of this liver disease.
Ethics approval(s)Approved 23/12/2021, South Central - Oxford B Research Ethics Committee (Ground Floor, Temple Quay House, 2 The Square, Bristol, BS1 6PN, UK; +44 207 104 8360; oxfordb.rec@hra.nhs.uk), ref: 21/SC/0408
Health condition(s) or problem(s) studiedCompensated cirrhosis due to non-alcoholic fatty liver disease
InterventionThe intervention is a low-energy total diet replacement programme with behavioural support (TDR) and has three phases.

In phase 1 (sole source TDR, weeks 0-16), participants will consume a nutritionally complete package of 4 formula products per day [soups, shakes, and bars (860 kcal/day)].

In phase 2 (food-re-introduction, weeks 17-22), products will be gradually reduced and replaced with food-based meals. During this phase, participants will consume 3 products per day for weeks 17-18, 2 products per day for weeks 19-20, and 1 product per day for weeks 21-22 together with food-based meals.

In phase 3 (weight maintenance, weeks 23-24), participants will consume food-based meals.

Participants will have contact with the dietitian for around 15 minutes each week (or 30 minutes fortnightly) over the 24 weeks for behavioural support. This will be over the phone or the app depending on participant preference.

Care as usual group: Participants in the comparator control group will receive care as usual which includes, but not limited to, advice for healthy eating and weight loss by their doctor. This will allow for a comparison of the study intervention to the existing standard of care.

Randomisation: Participants will be individually randomised with a 2:1 allocation to receive either the intervention or care as usual through minimisation with a 20% random element. The two stratified variables will be BMI (≥/< 35 kg/m2) and type 2 diabetes (yes/no).
