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.
