About this trial

This is a multicenter, randomized, controlled, open-label phase 1/2 clinical study conducted in China to evaluate the efficacy, safety and tolerability of hiHep cell-based bio-artificial liver support system (HepaCure) plus DPMAS versus DPMAS alone in Chinese subjects with acute-on-chronic liver failure(ACLF).

Phase 1 is a multicenter, open label study to evaluate the safety and tolerability of single dose and multiple doses of HepaCure with different treatment duration plus DPMAS in ACLF subjects respectively.

Phase 2 is a multicenter, randomized and controlled open label study to evaluate the efficacy, safety and tolerability of HepaCure plus DPMAS and LPE in ACLF subjects

Trial outcomes

Primary outcomes

1

Safety outcome

Based on the recorded adverse events (AE), serious adverse events (SAE), adverse events of special interest (AESI), and device deficiencies (such as leakage caused by the inherent quality issues of the plasma bio-purification column), the safety from the start of the study treatment until 14 days after the end of the study treatment was evaluated.(Phase I)

Time frame
From the initiation of treatment until 14 days after the end of study treatment.]
2

survival rate

The survival rate without liver transplantation at 12 weeks after the first treatment.(PhaseⅡ) Absolute change from baseline in the MELD score of subjects at week 4 after the first treatment. (PhaseⅡ)

Time frame
12 weeks after the initial treatment]
