Hetrombopag for Thrombocytopenia in Patients Scheduled for Elective Hepatic Interventional Diagnostic and Therapeutic Procedures: A Clinical Study

2 novembre 2026 mis à jour par: Gao-jun Teng, Zhongda Hospital

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
