Intervention model description: The investigators are undertaking a parallel group, multicenter, randomized controlled trial of 100 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.
Primary purpose: TREATMENT

Brief summary: 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).

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

Primary immune thrombocytopenia (ITP) confirmed by excluding other supervened causes of thrombocytopenia; Platelet count of less than 30×109/L at enrollment; Patients who did not achieve a sustained response to treatment with full-dose corticosteroids for a minimum duration of 4 weeks or who relapsed during steroid-tapering or after its discontinuation; 18 years older;

Exclusion Criteria:

Secondary immune thrombocytopenia (e.g., patients with HIV, HCV, Helicobacter pylori infection or patients with systemic lupus erythematosus) Congestive heart failure Severe arrhythmia Nursing or pregnant women Aspartate aminotransferase and alanine transaminase levels ≥ 3× the upper limit of the normal threshold criteria Creatinine or serum bilirubin levels each 1•5 times or more than the normal range Active or previous malignancy Unable to do blood routine test for the sake of time, distance, economic issues or other reasons.
