Use of F-652 in Patients With Alcoholic Hepatitis

Completed · Phase 1/Phase 2

Conditions studied: Alcoholic Hepatitis

In brief

Alcoholic hepatitis is a syndrome of progressive inflammatory liver injury associated with long-term heavy intake of ethanol. The pathogenesis is not completely understood. Patients who are severely affected present with subacute onset of fever, hepatomegaly, leukocytosis, marked impairment of liver function (e.g., jaundice, coagulopathy), and manifestations of portal hypertension (e.g., ascites, hepatic encephalopathy, variceal hemorrhage). However, milder forms of alcoholic hepatitis often do not cause any symptoms. Alcoholic hepatitis usually persists and progresses to cirrhosis if heavy alcohol use continues. If alcohol use ceases, alcoholic hepatitis resolves slowly over weeks to months, sometimes without permanent sequelae but often with residual cirrhosis. F-652 is a recombinant fusion protein containing human interleukin 22 (IL-22) and human Immunoglobulin G2 (IgG2)-Fc produced in CHO cells in serum-free culture. F-652 under development is intended to treat patients with graft vs host disease (GvHD) after bone marrow transplantation, and acute alcoholic hepatitis (AAH), a severe form of alcoholic liver disease (ALD). Both GvHD and AAH are diseases with unmet medical need. The current investigational new drug (IND) application is to conduct a phase Ia clinical study in GvHD patients to evaluate the safety and pharmacokinetic profile, and biomarkers of F-652 treatment by intravenous infusion (IV). IL-22 is a member of the IL-10 family of cytokines which control bacterial infection, homeostasis, and tissue repair. IL-22 may be used to treat patients with ALD because of its antioxidant, anti-apoptotic, anti-steatotic, anti-microbial, and proliferative effect that have been demonstrated in various experimental systems.

You may not qualify if…

• Other or concomitant cause of liver disease as a result of:
• Autoimmune liver disease
• Wilson disease
• Vascular liver disease
• Drug induced liver disease Note: Concurrent viral hepatitis is not excluded.
• Co-infection with human immunodeficiency virus (HIV)
• Any active malignancies other than curatively treated skin cancer (basal cell or squamous cell carcinomas) or any other malignancy diagnosed within the last five years.
• Active tuberculosis on chest x-ray at study entry
• Significant systemic or major illness other than liver disease, including coronary artery disease, cerebrovascular disease, pulmonary disease, renal failure, serious psychiatric disease, that, in the opinion of the Investigator would preclude the patient from participating in and completing the study
• Patients requiring the use of vasopressors or inotropic support
• Liver biopsy, if carried out, showing findings not compatible with alcoholic hepatitis
• Any patient that has received any investigational drug or device within 30 days of dosing or who is scheduled to receive another investigational drug or device in the course of the study Note: Investigational drug includes any drug that is used off-label.
