About this study
Official title: F573 for Injection for the Treatment of Liver Injury/Failure : Randomized, Double-blind, Placebo-controlled Phase Ⅱa Clinical Trial
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.).
Read the detailed description
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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.).
Detailed description
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.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing F573 for injection and Sterilizing water for injection in people with Acute Liver Failure and Acute-On-Chronic Liver Failure, run by Beijing Continent Pharmaceutical Co, Ltd. at 10 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 20 inclusion and 48 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 19 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 10 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact ling zhang, Dr (13501209210 ext. +86, zhangling@bjcontinent.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Adverse events (AE), serious adverse events (SAE) (time frame: 7 days of administration in the first stage and 14 days of administration in the second stage). The study lists 14 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Nov 2025.
