F573 for Injection for the Treatment of Liver Injury/Failure : Randomized, Double-blind, Placebo-controlled Phase Ⅱa Clinical Trial

Обзор

This study was a randomized, double-blind, placebo-controlled PhaseⅡ clinical trial . The primary objective of this study was to evaluate the safety of F573 for injection in patients with liver injury (drug-induced liver injury (DILI), chronic hepatitis B (CHB), intrahepatic cholestatic liver injury, etc.).

Подробное описание

In a randomized, double-blind, placebo-controlled design, the study was divided into two phases according to the subjects' risk of liver failure due to liver injury.

The first stage: Twenty-five patients with liver injury (DILI patients and other types of patients with the same degree of liver injury) were enrolled. The trial was first conducted in 16 participants who were treated with the experimental drug or placebo at a 1:1:1:1 ratio of 0.5, 1.0, and 2.0 mg/kg. Then, 9 patients with CHB were treated with the experimental drug, and the dose was determined to be 2.0 mg/kg according to the efficacy and safety test results of the 16 patients enrolled first.After subject consent is obtained, pharmacokinetic blood samples will be collected from 9 CHB patients subsequently enrolled in Phase I.

The second stage:A total of 24 patients with liver injury (DILI patients and intrahepatic cholestasis type liver injury) were enrolled, and qualified subjects were treated with the experimental drug or placebo in a ratio of 3:1, once a day for 14 days. The dosage was determined to be 0.5 mg/kg and 2.0 mg/kg based on the results of phase I efficacy and safety trials. First, a trial was conducted in the 0.5 mg/kg dose group, and 12 subjects were enrolled and treated with the test drug or placebo at a ratio of 3:1, once a day for 14 days. After the 0.5 mg/kg dose group was completed, the experiment of 2.0 mg/kg dose group was carried out. 12 subjects were also enrolled and received the test drug or placebo in a ratio of 3:1, once a day for 14 days.

The Third stage:

The study was randomized, double-blind, placebo-controlled. The study was divided into a screening period (14 days), treatment period (28 days), and follow-up period (90 days).

Eligible subjects were given the experimental drug or placebo in a ratio of 3:1, once a day for 28 days, and the dose was determined according to the efficacy and safety results of phase I and Phase II trials. Subjects also received the drug acetyl cysteine injection (NAC). After discontinuation, participants were followed for 90 days for safety. During the study, subjects were visited at planned sites for clinical laboratory examination, vital signs, physical examination, 12-lead electrocardiography, abdominal B-ultrasonography, cardiac color ultrasonography, biomarker testing, MELD score, AARC score, survival status assessment, monitoring of AE, and recording of subjects' concomitant/concomitant medications.
