A Study of Recombinant Human Albumin Injection to Treat Hypoalbuminemia in Cirrhotic Patients With Ascites

A Phase III Clinical Study of Recombinant Human Albumin Injection for the Treatment of Hypoalbuminemia in Cirrhotic Patients With Ascites

This study was a Phase III multicenter, blinded, and positive active-controlled clinical study to evaluate the efficacy, safety, and immunogenicity of recombinant human albumin(rHA) injection for the treatment of hypoalbuminemia in cirrhotic patients with ascites.

Study Overview

• Status: Completed
• Conditions: Hepatic Ascites
• Intervention / Treatment: Biological: Recombinant Human Albumin Injection; Biological: Human Albumin

Detailed Description

This study was a Phase III multicenter, blinded, and positive active-controlled clinical study to evaluate the efficacy, safety, and immunogenicity of recombinant human albumin(rHA) injection for the treatment of hypoalbuminemia in cirrhotic patients with ascites.After the primary efficacy endpoint ALB reaches the equivalence standard (-2 g/L to 2 g/L, test drug - control drug), a non-inferiority judgment will be made for the key secondary efficacy endpoint of the improvement rate of ascites depth (> -10%, test drug - control drug). Dosage: 20 g/day once daily for 7 days.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from baseline in ALB	The change in albumin (ALB) was determined by calculating the difference between the value measured after the last dose (immediately after the end of dosing) and the value measured before the first dose (the mean).	Day -1/7

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Improvement rate of ascites depth	Improvement of ascites depth is defined as: Ascites subside in patients with baseline grade 1 ascites (none Ascites);; Ascites degrade in patients with baseline grade 2 ascites (ascites grade 1 or no ascites) and ascites depth drop more than 1cm;; Ascites depth of patients with baseline ascites grade 2 decrease by ≥ 25% and the ascites depth drop more than 1cm.	Day -1/7
Clinical comprehensive improvement rate	The comprehensive clinical improvement was mainly based on changes in body weight and abdominal circumference. The classification and definition are: Significant improvement: weight loss ≥ 1 kg, abdominal circumference improvement ≥ 2 cm;; Improvement: weight loss ≥ 1 kg, abdominal circumference reduction less than 2 cm; or weight loss less than 1 kg, abdominal circumference reduction ≥2 cm;; General improvement: abdominal circumference reduction less than 2cm and weight loss less than 1 kg;; Unchanged: no change or abdominal circumference reduction less than 2 cm, no change in body weight or slight increase (increase less than 1 kg); or no change in weight or loss less than 1 kg, no change in abdominal circumference or slight increase (increase less than 2cm);; Deterioration: Weight increase ≥ 1 kg or abdominal circumference increase ≥ 2 cm;; Can not judge as classified above. Improvement rate is defined as the proportion of significant improvement and Improvement subject.	Day -1/7
