A Novel Extracorporeal Liver Support Therapy In ALCF and to Evaluate the Efficacy of DIALIVE 2.0, a Liver Dialysis Device.

This study is intended to demonstrate the efficacy and safety of the DIALIVE Liver Dialysis Device when incorporated into the standard management plan for participants with A-TANGO ACLF grade 2-4.

A total of 72 evaluable participants, aged 18-70, will be enrolled in up to 12 clinical centres in the United Kingdom. Participants must have a history of liver cirrhosis and a deterioration within four weeks due to a precipitating event, leading to A-TANGO ACLF grade 2-4. Multicenter, individually randomised, controlled, open-label, parallel group trial using double-arm design. The control group will receive SoC for participants with ACLF. The DIALIVE 2.0 treatment group will receive SoC with the addition of up to 7 (seven) daily DIALIVE 2.0 treatment sessions within the 10-day treatment window. Seventy-two participants with ACLF (60% A-TANGO ACLF grade 2 at randomisation, and 40% A-TANGO ACLF grade 3 \& 4 at randomisation) will be randomised 1:1 to receive either SoC or SoC + DIALIVE 2.0. This allows for 5% loss due to drop-out, and 5% censoring due to liver transplantation within 28 days. All randomised participants will be included in the intention to treat (ITT) analysis while all participants that receive at least one treatment cycle will be used for the safety population. For each participant, the study duration will be up to 105 days (screening: 5 days; treatment up to 10 days; follow up 90 days).

The total study duration is estimated to be approximately 18 months from screening of first participant until study completion of the last participant.
