E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
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.
|
Die Autoimmune Hepatitis ist eine chronische Entzündung der Leber, die durch eine Reaktion des Immunsystems gegen körpereigenes Lebergewebe ausgelöst wird. Die Ursachen hierfür sind bisher unklar. Die Behandlung der autoimmunen Hepatitis besteht in der Therapie mit sogenannten Immunsuppressiva, also Medikamenten, die das körpereigene Immunsystem schwächen und so die Reaktion gegen das körpereigene Lebergewebe unterdrücken. |

E.1.3 | Condition being studied is a rare disease | Yes |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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 |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives include quality of life during the trial, decreasing liver elastography as a marker for intrahepatic inflammation and the absence of weight gain. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Key inclusion criteria: 1. Patients with untreated autoimmune hepatitis diagnosed in ac-cordance to the „simplified criteria for the diagnosis of auto-immune hepatitis“ 2. Female patients: Female subjects must be postmenopausal, surgically sterile, of if premenopausal and not surgically ster-ile, be prepared to use 1 effective method of contraception during the study and for 6 months after the end of treatment visit*. 3.
