Brief Summary

Randomized, open-label, multicenter study to compare the efficacy and safety of Upadacitinib plus high-dose dexamethasone compared to high-dose dexamethasone monotherapy for the first-line treatment of adults with primary immune thrombocytopenia (ITP).

Detailed Description

The investigators are undertaking a parallel group, multicenter, randomized controlled trial of adults ITP patients in China. Patients were randomized to Upadacitinib + 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.
