* This trial is a Phase II clinical study, conducted in two stages:
* \*\*Phase IIa:\*\* A sentinel, single-arm design will be employed. A total of 12 early ACLF subjects are expected to be enrolled in the 0.5 mg/kg dose group. The first 2 subjects will serve as sentinels and be enrolled sequentially to receive a single intravenous dose. If no drug-related SAEs (Serious Adverse Events) occur in these 2 sentinel subjects within 2 weeks after the first dose, the remaining 10 subjects will be enrolled. Otherwise, the dose will be reduced for further exploration. After receiving a single intravenous dose, subjects will undergo a 20-day washout period. If no drug-related ≥Grade 3 AEs (Adverse Events) occur during this 20-day washout period, and safety/tolerability is jointly confirmed by the investi

📋 Eligibility rules (as published)
Stage IIa - Main inclusion criteria
1. The age of the signatories to the informed consent form must range from 18 to 75 years old (including the boundary values).
2. During screening, chronic plus acute liver failure was diagnosed based on the Guidelines for Diagnosis and Treatment of Liver Failure (2018 Edition) issued by the Liver Failure and Artificial Liver Group of the Infectious Diseases Branch of the Chinese Medical Association and the Severe Liver Disease and Artificial Liver Group of the Hepatology Branch of the Chinese Medical Association. Patients were in the early stage of acute liver failure (ACLF) and did not meet the criteria for liver transplantation.
Early manifestations of ACLF:
Severe fatigue accompanied by significant gastrointestinal symptoms such as marked anorexia, vomiting, and abdominal distension; ALT and/or AST levels remain significantly elevated, with progressive worsening of jaundice (TBil ≥ 171 μmol/L or daily increase ≥ 17.1 μmol/L); Hemorrhagic tendency is present in 30% of cases with PTA values ranging from \<30% to ≤40% (or INR values between 1.5 and \<1.9).
No complications or other extrahepatic organ failures were observed.
3. During the screening phase, serum TRAIL levels are elevated to ≥2 times that of normal individuals, or NK cell membrane-type TRAIL expression is increased.
4. Can comprehend the informed consent form, voluntarily participate in it, and sign it;
5. Capable of completing the trial in accordance with the study protocol;
6. Participants (including their partners) are willing to voluntarily adopt effective contraceptive measures from the screening stage through 6 months after the last administration of the investigational drug.
Stage IIb - Main inclusion criteria Individuals who do not meet any of the following criteria shall not be enrolled as subjects.
1. The age of the signatories to the informed consent form must range from 18 to 75 years old (including the boundary values).
2. The screening criteria were based on the "Guidelines for Diagnosis and Treatment of Liver Failure (2018 Edition)" issued by the Liver Failure and Artificial Liver Group of the Infectious Diseases Branch of the Chinese Medical Association and the Severe Liver Disease and Artificial Liver Group of the Hepatology Branch of the Chinese Medical Association, requiring a diagnosis of chronic plus acute liver failure at an early or intermediate stage of ACLF (Acute Complicated Liver Failure) and failure to meet the eligibility criteria for liver transplantation.
Early manifestations of liver failure:
Severe fatigue accompanied by significant gastrointestinal symptoms such as marked anorexia, vomiting, and abdominal distension; ALT and/or AST levels remain significantly elevated, with progressive worsening of jaundice (TBil ≥ 171 μmol/L or daily increase ≥ 17.1 μmol/L); Hemorrhagic tendency is present in 30% of cases with PTA values ranging from \<30% to ≤40% (or INR values between 1.5 and \<1.9).
No complications or other extrahepatic organ failures were observed.
Mid-stage manifestations of liver failure:
Based on the early manifestations of liver failure, the condition further progresses.
ALT and/or AST levels decline rapidly, while TBil continues to rise. The bleeding is evident (with petechiae or ecchymoses), with 20% \<PTA ≤ 30% (or 1.9 ≤ INR \<2.6).
Associated with one complication and/or one extrahepatic organ failure.
3. During the screening phase, serum TRAIL levels are elevated to ≥2 times that of normal individuals, or NK cell membrane-type TRAIL expression is increased.
4. Can comprehend the informed consent form, voluntarily participate in it, and sign it;
5. Can comply with the study protocol and complete the trial.
6. Participants (including their partners) are willing to voluntarily adopt effective contraceptive measures from the screening stage through 6 months after the last administration of the investigational drug.
Stage IIa - Main exclusion criteria
1. Patients with a history of allergic predisposition or severe hypersensitivity to protein-based drugs (CTCAE v5.0 grade\>3);
2. Patients who have undergone liver transplantation or plan to undergo liver transplantation within 1 month;
3. ACLF patients at intermediate or advanced stages;
4. Severe Grade III ascites or refractory ascites;
5. Associated with stage III-IV hepatic encephalopathy;
6. Patients with concurrent malignant tumors or a history of malignant tumors; those diagnosed with lung cancer, liver cancer, pancreatic cancer, or gastrointestinal tumors through imaging studies (ultrasound, CT, or MRI) and tumor marker tests (e.g., AFP, CEA, CA125, or CA199) during the screening period or within one month prior to it.
7. Patients during the screening period or within 1 month prior to screening whose endoscopic or imaging (abdominal ultrasound, CT, or MRI) findings indicate severe varices with a bleeding risk;
8. The KDIGO criteria for acute kidney injury (AKI) define the following subjects: (1) a serum creatinine (Scr) level increase of ≥26.5 μmol/L (0.3 mg/dL; 1 mg/dL = 88.4 μmol/L) within 48 hours; (2) a Scr increase of ≥1.5 times the baseline value within 7 days; and (3) reduced urine output (\<0.5 ml/kg/h) lasting for more than 6 hours.
9. The following laboratory test values are present or abnormal: a. Complete blood count: platelets (PLT) \<75×10⁹/L, hemoglobin (HGB) \<80 g/L; b. PT-INR ≥1.9 or PTA ≤30%; c. Left ventricular ejection fraction (LVEF) \<50%; serum creatinine\>1.5×ULN.
10. Those with severe respiratory dysfunction, dyspnea, or respiratory failure;
11. Severe infections that cannot be controlled by concomitant medications, including infections of major organs such as the abdominal cavity, lungs, urinary tract, and skin;
