Summary

The goal of this clinical trial is to test the MEX-CD1 hemodialysis medical device in patients suffering from ACLF. The main questions it aims to answer are: * Is the device safe when used according to the instructions for use? * Does the device work as expected by removing the excess of free iron from the blood? Patients will receive 3 MEX-CD1 Slow Low volume CVVHD within 1 week.

Detailed description

This study investigates the safety and performance of the MEX-CD1 slow low volume CVVHD device in patients suffering from ACLF. Acute-on-chronic liver failure (ACLF) is defined as a syndrome in patients with acutely decompensated cirrhosis, associated with single or multiple organ failures, and characterized by a high short-term mortality. ACLF is frequently triggered by a precipitating event (alcoholic hepatitis, infection, gastrointestinal haemorrhage) and characterized by an intense systemic inflammatory response driven per pathogen-associated molecular patterns (PAMPs) and/or damage-associated molecular patterns (DAMPs) responsible of the development of organs failure through tissues hypoperfusion, immune-mediated tissue damages and mitochondrial dysfunction. Very importantly, ACLF is a very dynamic syndrome that has potential for reversibility. It is hypothesized that the extraction of non-transferrin bound iron (NTBI) could break down the vicious cycle of the excessive inflammatory responses, reduce oxidative stress and inhibit pathogen proliferation in ACLF patients. As a consequence, it is hypothesized that the extraction of NTBI could promote improvement of ACLF grade n to ACLF grade n-1 or no ACLF. It is hypothesized that the extraction of NTBI could stop the progression of ACLF by preventing further organ failures and by reducing bacterial infection. Thereby, the extraction of NTBI could restore the eligibility of ACLF patients to liver transplantation, and, with or without liver transplantation, allow an earlier discharge from intensive care and prolong survival. The proposed medical device, by combining dialysis to a hyper-chelating colloidal dialysate (MEX-CD1), specifically extracts free iron from the blood. All patients enrolled in this study will receive 3 MEX-CD1 Slow Low volume CVVHD within 1 week. The duration of each MEX-CD1 Slow Low volume CVVHD session is 3h20.
