The present disclosure relates to a novel use and dosage regimens of the IL-Iβ binding antibodies canakinumab and gevokizumab, for treating or alleviating the symptoms of alcoholic hepatitis.
Excessive alcohol use is a major cause of liver disease in the Western world. Although it is not fully understood how alcohol damages the liver, chronic alcohol consumption results in the secretion of pro-inflammatory cytokines, oxidative stress, lipid peroxidation, and acetaldehyde toxicity, resulting in inflammation, apoptosis and eventually fibrosis of liver cells. The three most widely recognized steps of alcoholic liver disease are alcoholic fatty liver or alcoholic hepatic steatosis, alcoholic hepatitis and alcoholic cirrhosis. At least 80% of heavy drinkers develop steatosis, 10-35% develop alcoholic hepatitis and approximately 10% develop cirrhosis. Alcoholic hepatic steatosis, also called alcoholic fatty liver, consists in the occupation of a large proportion of the cytoplasm of affected hepatocytes by a single large triglyceride occlusion. This state is reversible by abstinence but may progress to cirrhosis if excess alcohol intake persists. Alcoholic hepatitis is the second main step of alcoholic liver disease and associates steatosis together with inflammation and necrosis, due to excessive intake of alcohol, and carries with it a significant mortality risk. Alcoholic cirrhosis is the most severe and terminal step of alcoholic liver disease and is characterized by fibrosis, leading to a progressive loss of liver function.
IL-1β is a pro-inflammatory cytokine produced by a variety of cell types, particularly mononuclear phagocytes, in response to injury, infection and inflammation. In alcoholic liver disease, IL-1β has been shown to be an important contributor to hepatic inflammation, leading to metabolic disturbances, fibrogenesis, stellate cell activation and portal hypertension. Thus, IL-1β represents a potential therapeutic target for treating or alleviating the symptoms of alcoholic hepatitis.
At present, recommended treatment options for alcoholic hepatitis include prednisolone, but this option carries with it a risk of higher incidence of infection, resulting in no survival advantage at 90 days.
Thus, there is an urgent need for new methods of preventing and/or ameliorating the effects of alcoholic hepatitis.
Accordingly, in one aspect, the present invention is directed to a method of treating or alleviating the symptoms of alcoholic hepatitis in a subject, comprising administering of 2-5 mg canakinumab per kg body weight to the subject.
In another aspect, the present invention is directed to canakinumab for use in treating or alleviating the symptoms of alcoholic hepatitis in a subject, comprising administering of 2-5 mg canakinumab per kg body weight to the subject.
In yet another aspect, the present invention is directed to the use of canakinumab for the manufacture of a medicament for treating or alleviating the symptoms of alcoholic hepatitis in a subject, comprising administering of 2-5 mg canakinumab per kg body weight to the subject.
The present invention is also directed to a method of treating or alleviating the symptoms of alcoholic hepatitis in a subject, comprising administering gevokizumab to the subject.
In another aspect, the present invention is directed to gevokizumab for use as a medicament for treating or alleviating the symptoms of alcoholic hepatitis in a subject, comprising administering gevokizumab to the subject.
In yet another aspect, the present invention is directed to the use of gevokizumab for the manufacture of a medicament for treating or alleviating the symptoms of alcoholic hepatitis in a subject, comprising administering gevokizumab to the subject.
Further features and advantages of the invention will become apparent from the following description.
Alcoholic hepatitis can range from mild hepatitis, with abnormal laboratory tests being the only indication of disease, to severe liver dysfunction with complications such as jaundice (yellow skin caused by bilirubin retention), hepatic encephalopathy (neurological dysfunction caused by liver failure), ascites (fluid accumulation in the abdomen), bleeding esophageal varices (varicose veins in the esophagus), abnormal blood clotting and coma. Alcoholic hepatitis is reversible if the patient stops drinking, but hepatitis usually takes several months to resolve. Alcoholic hepatitis can lead to liver scarring and cirrhosis. The typical findings on liver histology include hepatocellular necrosis and ballooning degeneration, and alcoholic Mallory's hyaline bodies (abnormal aggregations of cellular intermediate filament proteins indicative of fibrosis). Cholestasis is prominent. Severity of the disease can be classified according to Maddrey's discriminant function (mDF) (based on bilirubin and prothrombin time), Glasgow alcoholic hepatitis score (based on age, white blood cell count, urea, prothrombin time and bilirubin) or Model for End Stage Liver Disease (MELD) score (based on creatinine, bilirubin and INR) (Lucey et al. (2009) N. Engl. J. Med., 360(26), 2758-2769; Vergis et al. (2017) Gastroenterology. 2017 April; 152(5):1068-1077.e4). Alcoholic hepatitis is classified as severe when the mDF is 32.
The present invention provides, inter alia, methods of treating or alleviating the symptoms of alcoholic hepatitis in a subject, comprising administering of 2-5 mg canakinumab per kg body weight to the subject.
Canakinumab (international nonproprietary name (INN) number 8836) is disclosed in WO02/16436, which is hereby incorporated by reference in its entirety. Canakinumab is a fully human monoclonal anti-human IL-1β antibody of the IgG1/k isotype, and is approved under the trade name Ilaris® for the treatment of IL-1β driven inflammatory diseases. It is designed to bind to human IL-1β, and thereby blocking the interaction of the cytokine with its receptors. The antagonism of IL-1β mediated inflammation using canakinumab in lowering high sensitivity C-reactive protein (hsCRP) and other inflammatory marker levels has shown an acute phase response in patients with Cryopyrin-Associated Periodic Syndrome (CAPS) and rheumatoid arthritis.
Also provided is a method of treating or alleviating the symptoms of alcoholic hepatitis in a subject, comprising administering gevokizumab to the subject.
Gevokizumab (XOMA-052) is a high-affinity, humanized monoclonal antibody of the IgG2 isotype to interleukin-1β, developed for the treatment of IL-1β driven inflammatory diseases. Gevokizumab modulates IL-1β binding to its signaling receptor. Gevokizumab is disclosed in WO2007/002261, which is hereby incorporated by reference in its entirety.

The Maddrey discriminant function (mDF) is a model for evaluating the severity and prognosis in alcoholic hepatitis and evaluates the efficacy of steroid treatment in alcoholic hepatitis. The mDF score is a statistical model useful for predicting a subject's short term prognosis, in particular mortality within 30 or 90 days. A score of 32 or greater implies poor outcome with 30 day mortality ranging between 35% to 45%. The mDF is calculated according to the formula:
mDF=4.6×(Prothrombin time(PTPATIENT−PTCONTROL)+Serum Bilirubin(μmol/l)/17.1

Previous studies with anti-cytokine therapy in alcoholic hepatitis, targeting the TNF-α system, have failed to show a survival benefit due to the increased risk of infection and possibly due to the removal of a regenerative signal provided by TNF-α (Boetticher et al. (2008) Gastroenterology, 135(6):1953-60). The overall risk of infection in alcoholic hepatitis is 20-30% but this is increased 3-4 fold in patients treated with immunosuppressive drugs such as prednisolone when the pre-treatment bacterial 16S ribosomal DNA (16S rDNA) in blood is >18.5 pg/ml (Vergis et al., 2017). Accordingly, subjects at high risk of bacterial infection may receive prophylactic antibiotics. Herein, high risk of bacterial infection is characterized by levels of 16S ribosomal DNA (16S rDNA) in blood of >18.5 pg/ml.
Accordingly, in one embodiment canakinumab is used in treating or alleviating the symptoms of alcoholic hepatitis in a subject, wherein antibiotics are administered for at least 14 days following first administration of canakinumab and wherein the subject is at high risk of bacterial infection characterized by levels of 16S ribosomal DNA (16S rDNA) in the blood of >18.5 pg/ml.

Without intending to limit the scope of the invention in any way, it is further described by way of illustration of the following example.
A Multicenter, Double Blind, Randomized (1:1), Placebo Controlled Trial Evaluating the Efficacy, Safety and Tolerability of Canakinumab in Patients with Alcoholic Hepatitis
Alcoholic hepatitis patients eligible for inclusion in this study must fulfill all of the following criteria:
As per standard of care all patients are screened for infection prior to randomization. Diagnosis of infection is based on the criteria outlined by Bajaj et al. and involves chest radiography, urinalysis (mid-stream urine (MSU) culture if urinalysis positive), ascitic tap (if ascites present) and blood cultures if pyrexial. Positive culture and initiation of antibiotics with clinical or radiological signs of infection, as well as clinical suspicion, are recorded as sepsis. Blood culture negative pyrexia and a leucocytosis are not regarded as signs of active sepsis on their own, as these are often co-existent findings with alcoholic hepatitis. Patients with evidence of sepsis are treated for a minimum of 2 days with appropriate antibiotics before re-screening. Once the local Principal Investigator (PI) considers that the sepsis is under control, the patient may be re-screened and randomised if eligible. Patients with baseline infection should continue antibiotic treatment for 2 weeks after initiation of treatment.
Bacterial DNA is measured on whole blood samples (EDTA tube) at screening. Patients found to have bacterial DNA (16S rDNA)>18.5 pg/ml are treated with prophylactic antibiotics (co-amoxyclav or ciprofloxacin) for the first 14 days treatment irrespective of whether they are randomized to canakinumab or placebo. Patients are screened for infection at baseline and on a weekly basis.
Patients are included and randomized and treated before histology result is available. If the histology is negative then patient is withdrawn.
A single dose of 3 mg/kg Canakinumab or identical placebo is administered intravenously at baseline (Day 1).
Patients with AST >2×ULN on Day 28 receive a second dose of 3 mg/kg study drug administered intravenously (i.v.) on Day 28:
Histological improvement of alcoholic hepatitis on liver biopsy 28 days after initial administration of canakinumab compared to baseline. Histological improvement is defined as reduction in lobular inflammation, regardless of cell type.
