简要总结
The project was undertaken by Qilu Hospital, Shandong University in China. In order to report the efficacy and safety of dexamethasone combined with rituximab, cyclosporin and intravenous immunoglobulin in the management of newly diagnosed ITP patients.
详细描述
The investigators are undertaking a multicenter trial of 100 primary ITP adult patients from 5 medical centers in China. All participants receive dexamethasone (given orally at a dose of 40 mg per day for 4 days), rituximab (given intravenously at a dose of 500mg once), cyclosporin (given orally at a dose of 2.5-3 mg/kg per day for 28 days) and intravenous immunoglobulin (given intravenously at a dose of 5g per month for 6 months) for the treatment of adults newly diagnosed ITP patients.

研究组 & 干预措施
Treatment group
DEX Combined With RTX, CSA and IVIG All patients are assigned to receive dexamethasone (given orally at a dose of 40 mg per day for 4 days), rituximab (given intravenously at a dose of 500mg once), cyclosporin (given orally at a dose of 2.5-3 mg/kg per day for 28 days) and intravenous immunoglobulin (given intravenously at a dose of 5g per month for 6 months) for the treatment of adults newly diagnosed ITP patients.
干预措施: DEX Combined With RTX, CSA and IVIG (Drug)
结局指标
主要结局
Evaluation of platelet response (Complete Response)
时间窗: The time frame is up to 3 months per subject
CR. A complete response (CR) was defined as a sustained (≥ 3 months) platelet count ≥ 100×10\^9/L
Evaluation of platelet response (Response)
时间窗: The time frame is up to 3 months per subject
R. A response (R) was defined as a sustained (≥ 3 months) platelet count ≥ 30×10\^9/L without recurrence of thrombocytopenia.
Evaluation of platelet response (No Response)
时间窗: The time frame is up to 3 months per subject
NR.No response (NR) was defined as platelet count \< 30 × 10\^9/L or a less than two fold increase in platelet count from baseline or the presence of bleeding. Platelet count must be measured on two occasions more than a day apart.
Evaluation of platelet response (relapses)
时间窗: The time frame is up to 9 months per subject
A relapses was defined as platelet count falls below 30×10\^9/L or bleeding accrues after achieving R or CR.
次要结局
- The number and frequency of therapy associated adverse events(up to 9 months per subject)
