Alcoholic hepatitis (AH) is a florid presentation of alcoholic liver disease characterized by liver failure in the context of recent and heavy alcohol consumption. The condition carries a high fatality risk; patients with severe AH have a 30% mortality rate at 90 days after presentation. Currently there is no effective treatment for severe alcoholic hepatitis. Based on the current understanding of the disease pathogenesis IL-1 (interleukin) is a key mediator of hepatic inflammation responsible for metabolic disturbances, fibrogenesis stellate cell activation and consequently portal hypertension. Canakinumab is a licensed monoclonal antibody inhibitor of IL-1 and may consequently reverse the adverse effects of the cytokine in patients with this disorder. Therefore, the main objective of the ISAIAH trial is to explore the potential benefits of the IL-1β antibody, Canakinumab (solution for injection), in the treatment of alcoholic hepatitis. ISAIAH is a multicentre, double blind, randomized (1:1), placebo controlled trial. The trial will follow patients up for 90 days and will be conducted in centres across the United Kingdom. Twenty-six patients will be recruited to each arm of the trial: total 52 patients.

ISAIAH is a multicentre, double blind, randomized (1:1), placebo controlled trial. The trial will follow patients up for 90 days and will be conducted in centres across the United Kingdom. Twenty-six patients will be recruited to each arm of the trial: total 52 patients. The trial will be conducted in patients with severe alcoholic hepatitis (mDF\* ≥ 32 and MELD ≤27) with treatment initiated during an index hospital admission with the condition. The primary endpoint of the trial is histological improvement of alcoholic hepatitis on liver biopsy after 28 days of treatment compared to baseline. Histological improvement is defined as a reduction in lobular inflammation (regardless of cell type). Patients meeting the eligibility criteria will be randomized and treated. A single dose of 3 mg/kg Canakinumab or identical placebo will be administered intravenously at baseline (Day 1). Canakinumab will be made up by dilution in 100 ml 5% Dextrose by an unblinded research personnel at each site. Patients with AST \>2 x ULN on Day 28 will receive a second dose of 3 mg/kg study drug administered i.v. on Day 28. Patients who received placebo on baseline will receive placebo. Patients who received canakinumab on baseline will receive canakinumab. Total follow up time for each patient is 90 days.

Number of Patients Presenting Histological Improvement of Alcoholic Hepatitis on Liver Biopsy After 28 Days of Treatment Compared to Baseline.
Histological improvement is defined as a reduction in lobular inflammation (regardless of cell type).
Time frame: Baseline and 28 days
Difference in Proportions of Participants With Improvement of Polymorphonuclear Cell Infiltrate From Baseline to Day 28.
Improvement will be recorded as a binary Yes/No outcome. The outcome will be analysed as the proportion of patients, within each treatment group, with improvement on each individual component (polymorphonuclear cell infiltrate, ballooned hepatocytes and steatosis).
Time frame: Baseline and 28 days
Number of Patients Presenting Changes in Degree of Fibrosis (AHHS) From Baseline to Day 28
Where presence of bridging fibrosis or Cirrhosis at day 28 is the outcome. Firth logistic regression model was used. An intercept term and treatment indicator are the only predictor variables.
Time frame: Baseline and 28 days
Number of Participants Presenting Changes in Steatosis Grade (NAS) From Baseline to Day 28
Number of patients in whom the histological degree of liver steatosis improved between baseline and day 28. Steatosis is assessed using an ordinal scale (1,2,3,4). There are four categories of steatosis grade: (1) \<5%, (2) 5% to 33%, (3) \>33% to 66%, and (4) \>66% Ordinal logistic regression was used for statistical analysis
Time frame: 28 days
Number of Participants Presenting Changes in Hepatic Venous Pressure Gradient (HVPG) Between Baseline and Day 28
This outcome measure was included in the protocol as a secondary objective. However, no data was generated as HVPG is difficult to obtain and the outcome measure was therefore abandoned
Time frame: 28 days
Number of Participants Presenting Changes in Serum CK18-M30/M65 From Baseline to Day 7, 14, 21, 28, 42 and 90
Samples were not available. It was reported as a SAP deviation in the final statistical report.
Time frame: Baseline and 7, 14, 21, 28, 42, 90 days
Change in Serum Bilirubin Concentration From Baseline to Day 28
Time frame: 28 days
Change in MELD (Model For End-Stage Liver Disease) Score at From Baseline to Day 28
MELD score is based on the following formula: MELD Score = (9.57 \* ln(Creatinine)) + (3.78 \* ln(Bilirubin)) + (11.2 \* ln(INR)) + 6.43. Higher score is a worse outcome. Minimum value is around 9 and maximum value is around 40.
Time frame: Day 0 to day 28
Change in Glasgow Alcoholic Hepatitis Score (GAHS) From Day 28
Predicts mortality in patients with alcoholic hepatitis by laboratory results and age. GAHS score is calculated after Forrest et al., 2007 where a score of 5 to 12 is assigned based on age, WCC, Urea, PT ratio or INR and bilirubin. Higher score means a worse outcome and a score greater than or equal to 9 is associated with a poor prognosis. Outcome measure is the score at day 28 - score at day 0
Time frame: Day 0 to day 28
Change in Maddrey's Discriminant Function (mDF) Score From Baseline to Day 28
mDF is calculated using the following formula: mDF = 4.6 x (Prothrombin time - control time) + Serum Bilirubin (μmol/l) / 17. A higher score is associated with poorer prognosis. A value more than 32 implies poor outcome.
Time frame: 28 days
Lille Score at Day 7
Lille score is calculated as Exp(-R)/\[1+exp(-R)\] where R = \[3.19 - (0.101\*age in years)\] + (1.47\*albumin at baseline in g/dL) + \[0.28215\* (bilirubin at baseline - bilirubin at Day 8 in mg/dL)\] - \[0.206 \* (if creatinine\>=1.3 mg/dL at baseline)\] - \[0.11115\*bilirubin baseline in mg/dL\] - (0.0096\*Prothrombin Time in seconds at baseline). The Lille Model predicts mortality rates within 6 months. Scores \>0.45 predict a 6-month survival of 25%. Scores \<0.45 predict a 6-month survival of 85%.
Time frame: 7 days
