Hetrombopag for Thrombocytopenia in Patients Scheduled for Elective Hepatic Interventional Diagnostic and Therapeutic Procedures: A Clinical Study
A Clinical Study to Evaluate the Efficacy and Safety of Hetrombopag in the Treatment of Thrombocytopenia in Patients Undergoing Elective Hepatic Interventional Diagnostic and Therapeutic Procedures
This is a prospective, multicenter, open-label, randomized controlled clinical study. It includes three phases: screening period, treatment period and follow-up period. A total of 108 adult patients with thrombocytopenia (PLT < 50×10⁹/L) scheduled for elective hepatic interventional procedures will be enrolled.

- Voluntarily participating in this study, providing signed informed consent, and having good compliance
Exclusion Criteria:
- Presence of other diseases that may cause thrombocytopenia, including but not limited to: aplastic anemia, myelodysplastic syndromes, chronic myeloproliferative neoplasms, congenital thrombocytopenia, drug-induced thrombocytopenia, immune thrombocytopenia, thrombocytopenia secondary to rheumatic immune diseases, etc.
- Previous or current arterial or venous thrombosis, including partial or complete thrombosis
- History of portal vein thrombosis and/or main portal vein tumor thrombus; and/or evidence of portal vein thrombosis on ultrasound, CT, or MRI during screening; and/or absence of hepatopetal portal venous flow on Doppler ultrasound; and/or portal venous flow velocity < 10 cm/s
- Scheduled for open abdominal surgery such as hepatectomy or liver transplantation
- Received platelet-increasing procedures within 90 days prior to randomization, including partial splenic artery embolization, splenic radiofrequency/microwave ablation, high-intensity focused ultrasound (HIFU) of the spleen, three-dimensional conformal therapy of the spleen, etc.
- Previous history of liver transplantation or splenectomy
- At screening, any of the following: significant liver function abnormality with ALT/AST >3×ULN or TBL >2×ULN; hepatic encephalopathy with Child-Pugh hepatic encephalopathy score of 3 (occasional coma), irrespective of hepatic encephalopathy treatment; medication-refractory ascites
- Bleeding score ≥ grade 2 according to the WHO bleeding scale prior to randomization, or history or evidence of diseases with bleeding risk
- Received platelet transfusion or platelet-containing blood products (excluding red blood cells) within 3 days prior to randomization
- Received any of the following medications within 14 days prior to randomization: TPO (e.g., rhTPO), other TPO-RA agents, recombinant human interleukin-11 (IL-11), etc.
