简要总结
Randomized, open-label, multicenter study to compare the efficacy and safety of combination of Sitagliptin and danazol versus danazol for the treatment of adults with steroid-resistant/relapse immune thrombocytopenia (ITP).
详细描述
The investigators are undertaking a parallel group, multicenter, randomized controlled trial of 120 adults with steroid-resistant/relapse ITP in China. Patients were randomized to Sitagliptin plus danazol and danazol monotherapy group. Platelet count, bleeding and other symptoms were evaluated before and after treatment. Adverse events are also recorded throughout the study.
