Clinical Trial Summary

This study aims to investigate the efficacy and safety of avatrombopag for treating thrombocytopenia in hepatitis b virus related acute-on-chronic liver failure patients receiving artificial liver support system treatment.


Clinical Trial Description

Artificial liver support system (ALSS) is an optimal therapy in patients with hepatitis b virus (HBV) related acute-on-chronic liver failure (ACLF). But a lot of patients encount thrombocytopenia (TCP) due to the mechanical damage of thrombocyte and use of heparin during the treatment. Avatrombopag is an oral thrombopoietin receptor agonist that has been recently approved for treating TCP in chronic liver disease patients needing invasive procedures. Therefore, this study aims to investigate the efficacy and safety of avatrombopag for treating TCP in HBV related ACLF patients receiving ALSS treatment. Sixty patients with HBV related ACLF receiving ALSS will be enrolled in this study. The participants are divided into trial group (avatrombopag, double plasma molecular adsorption system (DPMAS) , low volume plasma exchange (LPE), and comprehensive internal medical treatment) and control group (DPMAS, LPE, comprehensive internal medical treatment). Symptoms, signs, laboratory tests results, adverse events, mortality rates are recorded from treatment baseline to 3 weeks. ;
