Recombinant Human Serum Albumin(Protgen Ltd.)

Phase III stage Main purpose: Using the change of serum albumin concentration from baseline immediately after the last intravenous administration as an indicator, evaluate the efficacy of recombinant human serum albumin in patients with cirrhosis and ascites. Secondary objectives: 1) Evaluate the efficacy of recombinant human serum albumin in patients with cirrhosis and ascites based on other efficacy evaluation indicators; 2) Evaluate the safety of recombinant human serum albumin in subjects with cirrhosis and ascites; 3) Evaluate the pharmacodynamic (PD) characteristics of recombinant human serum albumin in subjects with cirrhosis and ascites; 4) Evaluate the immunogenicity of recombinant human serum albumin in subjects with cirrhosis and ascites. Exploratory purpose: To evaluate the effect of recombinant human serum albumin on glycated albumin and glycated hemoglobin in patients with cirrhosis and ascites.
