Use of F-652 in Patients With Alcoholic Hepatitis

Phase 1

Completed

Conditions: Alcoholic Hepatitis

Interventions: Drug: F-652

Registration Number: NCT02655510

Lead Sponsor: Mayo Clinic

Brief Summary: 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.

The sponsor has developed F-652, a recombinant human IL-22 IgG2 Fc fusion protein produced in serum-free culture of Chinese Hamster Ovary (CHO) cells. F-652 is able to protect tissue from damage and enhance tissue repair during the inflammation process and infection by activation of STAT3 mediated by the interleukin-22 receptor subunit 1 (IL-22R1) expressed on epithelial cells such as hepatocytes.

Arm && Interventions

Group	Intervention	Description
F-652	F-652	Participants will receive 10 μg/kg, 30 μg/kg or 45 μg/kg of F-652 on Day 1 and Day 7 via slow intravenous infusion. Three patients with MELD 11-20 will receive 10 μg/kg of F-652. Pharmacokinetic testing will be completed on these subjects. If evaluations demonstrate safety and efficacy signals, the next 3 patients will receive 30 μg/kg. If pharmacokinetic testing demonstrates safety and efficacy signals, the next 3 patients will receive 45 μg/kg. After demonstrating absence of side effects in this group, patients in MELD 21-28 will follow the same dose escalation regiment as the MELD 11-20 group.
