a study to evaluate the efficacy and safety of osrhsa in patients of hepatic cirrhosis with hypoalbuminemia

Conditions: Hypoalbuminemia; Hepatic Cirrhosis

Summary: the goal of this clinical trial is to evaluate the efficacy of osrhsa works to treat hypoalbuminemia in hepatic cirrhosis patients. it will also learn about the safety and immunogenicity of osrhsa. the main question it aims to answer is whether osrhsa is effective in elevating the serum albumin level of cirrhotic patients with hypoalbuminemia. researchers will compare osrhsa to the positive comparator, plasma-derived hsa (phsa) to see if osrhsa presents as non-inferior to phsa in the indication of hypoalbuminemia in hepatic cirrhosis patients. participants will be randomized in a 1:1 ratio to receive osrhsa or hphsa (20g iv qd) for up to 14 days, following an eot visit. follow-up visits will be taken on eot+7d, eot+14d, and eot+30d, respectively.
