Background and study aims
Liver failure occurs when liver cells are damaged significantly and are no longer able to function. In some patients their liver may suddenly stop working and this is known as acute liver failure. In these patients they may have no evidence of liver disease before being hospitalised. In other patients the liver may already have sustained damage but has managed to keep functioning well then something happens which means that it is no longer able to perform all its functions adequately. This is known as acute decompensation of cirrhosis. Cirrhosis is the result of long-term damage to the liver which causes scarring. Patients with liver failure have increased susceptibility to infection which usually leads to further deterioration in liver function. The purpose of this study is to investigate how we can improve the function of immune cells in patients with liver failure, ultimately helping to reduce infection. There is no expectation that liver function will be restored. The researchers will be collecting samples and data to investigate whether an anti-PD1 drug can be used to help defects in the immune response in patients with liver failure. There is currently no targeted treatment for this.

Who can participate?
Patients aged 18 years and over with acute liver failure (ALF) or acute decompensation of cirrhosis (AD)

What does the study involve?
The study involves a single dose of a drug (nivolumab) by injection. Blood samples will be taken before the injection and then every 5 days for 20 days.

What are the possible benefits and risks of participating?
There is no guarantee of any benefit from participating in this study. There is a small risk that the drug could cause temporary inflammation of the liver.

Where is the study run from?
Imperial College London (UK)

Ethics approval(s)

Approved 22/11/2022, Harrow Research Ethics Committee (Level 3, Block B, Whitefriars, Bristol Research Ethics Committee Centre, Bristol, BS1 2NT, United Kingdom; +44 (0)207 104 8012; harrow.rec@hra.nhs.uk), ref: 22/LO/0397

Health condition(s) or problem(s) studiedLiver failure (acute liver failure and acute decompensation of cirrhosis)
InterventionNivolumab (anti-PD1 antibody)

Non-CTIMP, physiological assessment in two groups of patients:
1. Patients (n = 19) with acute liver failure (ALF)
2. Patients (n=59) with acute decompensation of cirrhosis (AD)

The study will follow patients up for 30 days. Patients should commence treatment within 48 hours of study enrolment. Anti-PD1 antibody (nivolumab or pembrolizumab) will be administered as a single 240 / 200 mg dose (120 / 100 mg dose in the first sentinel cohort patients) diluted in 100 ml of 0.9% saline and administered intravenously over 30 minutes.
Intervention typeBiological/Vaccine
Pharmaceutical study type(s)Physiological assessment of response to PD1 inhibition
PhasePhase 0
Drug / device / biological / vaccine name(s)Nivolumab, pembrolizumab
Primary outcome measureHLA-DR expression on circulating monocytes measured using flow cytometry on day 15 compared to baseline
Secondary outcome measures1. Monocyte phagocytosis measured using pH-Rodo uptake in flow cytometry on days 5, 10, 15 and 30 compared to baseline
2. HLA-DR expression on circulating monocytes measured using flow cytometry on days 5, 10, 15 and 30 compared to baseline
3. Incidence of clinically diagnosed infection during the 30 days of follow-up
4. Incidence of bacteraemia diagnosed on blood cultures during the 30 days of follow-up
5. Changes in lipopolysaccharide-induced tumour necrosis factor alpha secretion from monocytes measured by ELISA test on days 5 and 15 compared to baseline
6. Changes in circulating bacterial 16S-ribosomal DNA (16S-rDNA) at days 5 and 10 compared to baseline measured using real-time polymerase chain reaction assays
