简要总结
Randomized, open-label, multicenter study to compare the efficacy and safety of zanubrutinib plus high-dose dexamethasone compared to high-dose dexamethasone monotherapy for the first-line treatment of adults with primary immune thrombocytopenia (ITP).
详细描述
The investigators are undertaking a parallel group, multicenter, randomized controlled trial of patients with ITP in China. Patients were randomized to Zanubrutinib + high-dose dexamethasone and high-dose dexamethasone monotherapy group. Platelet count, bleeding and other symptoms were evaluated before and after treatment. Adverse events are also recorded throughout the study.
