Using miroliverELAP to treat acute liver failure

A Phase 1 Prospective Study of the Miromatrix External Liver Assist Product (miroliverELAP®) for Liver Support in Adults With Acute Liver Failure.

Phase 1 Interventional Miromatrix Medical Inc. · NCT06285253

This study is testing a new treatment using a special liver device to see if it can help people with acute liver failure recover or find out if they need a transplant.

What this trial studies

This phase 1 clinical trial evaluates the safety of miroliverELAP, a bioengineered liver graft combined with an extracorporeal blood circuit, for patients experiencing acute liver failure without chronic liver disease. Participants will receive continuous treatment for 48 hours, during which the study will monitor survival rates, adverse events, and changes in specific biomarkers related to liver function. The trial aims to determine if this innovative approach can support liver recovery or identify candidates for transplantation. A minimum of 5 subjects will be treated, with follow-up assessments extending for 32 days post-treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 diagnosed with acute liver failure and not eligible for liver transplantation.

Not a fit: Patients with underlying chronic liver disease or those who have previously undergone a liver transplant will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a critical support mechanism for patients with acute liver failure, potentially improving survival rates and outcomes.

How similar studies have performed: While this approach is innovative, similar studies exploring bioengineered liver support systems have shown promise, indicating potential for success.
