Eligibility Criteria
You may qualify if:
- \. Patients with cirrhosis caused by chronic liver disease who have been diagnosed by biopsy/imaging (Child-Pugh class A, B, and C).
- \. Life expectancy≥3 months.
- \. Platelet count≤80×109/ L.
- \. Fertile female subjects with a negative pregnancy test during the screening period and who agree to take effective contraceptive methods Throughout the study period will be eligible for this study.
- \. Voluntary written informed consent.
You may not qualify if:
- Subjects allergic to any component of investigational drug.
- Subjects with cirrhosis caused by drug-induced liver injury.
- Subjects with history of splenectomy or liver transplantation.
- Liver cirrhosis with serious complications, including: hepatic encephalopathy, intractable ascites, upper gastrointestinal bleeding, etc.
- Subjects with Liver failure.
- Tthe presence of portal vein thrombosis or tumor thrombus was indicated by doppler ultrasound or CT or MRI and other imaging examinations within 3 months prior to the beginning of screening.
- Subjects with history of arterial or venous thromboembolism, or with thromboembolic disease, or with high risk factors for thrombosis, or with a hereditary tendency to thrombosis, including Antithrombin III deficiency, etc.
- Subjects with history of any disease other than chronic liver disease and cirrhosis that may result in decreased platelet count and/or abnormal platelet function, including aplastic anemia, myelodysplastic syndrome (MDS), bone marrow fibrosis, etc.;
- Subjects with diseases with higher bleeding risk, such as coagulation factor deficiency or Vascular pseudohemophilia factor deficiency.
- Subjects with severe infections that are not effectively controlled.
- Past or present history with any serious disease except liver disease, including: angina, severe arrhythmia, myocardial infarction, heart failure, Cerebral hemorrhage, cerebral infarction, intracranial infection, Renal insufficiency( creatinine clearance rate ≤50 mL/min ),as well as any other diseases that have been judged by investigator to be unsuitable for this study.
- Subjects who had undergone trans jugular intrahepatic portal shunt (TIPS);
- Subjects with Anti-HIV positive antibodies or Anti- TPHA positive antibodies.
- Subjects who received any therapy with increased platelet count within the 3 weeks or platelet transfusion within 2 weeks before randomization.
- No more than 30 days or 5 half-lives after investigational drug treatment for other studies (whichever is longer).
- +6 more criteria
