Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients with cirrhosis, muscle weakness as defined by handgrip dynamometer and evidence of low serum albumin or ascites will be invited to participate in the study. 150 patients will be recruited and randomised to the intervention arm and a control arm. The intervention arm will be blinded to receive powdered BCAA supplements. These contain leucine, isoleucine and valine in a 2:1:1 ratio respectively. Patients in the intervention arm will be given powdered BCAA supplements and will be asked to take 30g orally per day mixed with water, milk or juice. The duration of intervention will be 12 months. Compliance will be monitored through return and weighing of supplement packages at each clinical review.
Intervention code [1] 300499 0
Treatment: Drugs
Comparator / control treatment
Patients randomised to the control arm will be given a whey protein isolate powder with equal protein content to BCAA supplement. They will be asked to take 30g orally per day for 12 months.
Control group
Active

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will occur independently through the pharmacy department. Patients will be administered the intervention or standard of care supplement powder in unlabelled packaging. The investigator and participant will be blinded to intervention group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data

Phase
Phase 2
Type of endpoint/s
Statistical methods / analysis
To detect a difference at 12 months between the intervention and control group using the composite endpoints of a difference of 5% in upper limb appendicular muscle mass on DEXA and / or 5% increase in handgrip strenght, with a p-value set at 0.05 and a power of 80%, we estimate that each group will need 67 subjects. We estimate a drop-out rate of up to 10%, therefore we aim to recruit 150 patients.

Outcomes will be analysed on an intention to treat analysis. While most subjects will reach at least 6 months in the study some may drop because of transplantation or death. Those who achieve between 6 and 12 months follow up will be included in the intention to treat analysis provided a DEXA is completed allowing for documentation of APLM. If anything, this will skew results to the null hypothesis as less of a change in APLM is expected at only 6 months follow up compared to the intended duration of 12 months. Therefore, if anything, dropouts may lead to an under-estimation of treatment effect and minimize the risk of identifying a false positive result.
