Health Condition(s) or Problem(s) studied

Autoimmune Hepatitis (AIH); rare inflammatory liver disease associated with elevated transaminases, elevated Immunoglobulin G, the presence of autoantibodies and interface hepatitis in liver histology. Untreated, AIH progresses to liver fibrosis and cirrhosis with its complications. Historical placebo-controlled studies could show a mortality of around 70% in the placebo-treated group.

Therapeutic area: Diseases [C] - Immune System Diseases [C20]

Intervention(s)

Trade Name: Inflectra (Infliximab)
Pharmaceutical Form: Concentrate for solution for infusion

Primary Outcome(s)

Timepoint(s) of evaluation of this end point: At month 6

Main Objective: Steroid treatment is often wearing and may reduce treatment adherence due to multiple side effects. Currently, there is no alternative treatment available for induction treatment of AIH. There are small case series using cyclophosphamide or intravenous cyclosporine A as an induction treatment, but due to toxic side effects, this only serves as an emergency treatment. The rationale of this trial is to show the efficacy of infliximab in the induction treatment for AIH. The primary objective of the AIH-MAB trial is to show that infliximab induces biochemical remission in treatment-naïve patients with auto-immune hepatitis

Primary end point(s): Biochemical remission of autoimmune hepatitis defined as normalization of AST, ALT and IgG at month 6.

Secondary Objective: Secondary objectives include quality of life during the trial, decreasing liver elastography as a marker for intrahepatic inflammation and the absence of weight gain.

Secondary Outcome(s)

Timepoint(s) of evaluation of this end point: at week 0, 4, 12, 24 and 48/End of study
at Screening, Week 12, 36, 48/End of Study
each week until EOS

Secondary end point(s): Stable Quality of life (using standardized tools including the GAD-7, PHQ-9 and SF-12) at week 0, 4, 12, 24 and 48.
Decrease in Elastography
Absence of weight gain
