研究组 & 干预措施
p-ALG+Romiplostim N01+CsA
The maximum screening period was 4 weeks, and after entering the treatment period, the patients were treated with p-ALG combined with cyclosporine and Romiplostim N01. Symptomatic leukocyte elevation, blood transfusion support, and anti-infective therapy are allowed during this period, according to the patient's blood routine. If a patient has a serious adverse event during treatment, it will be treated according to the criteria for suspension and recovery.
干预措施: standard IST combined with Romiplostim N01 (Drug)
结局指标
主要结局
Overall response rate
时间窗: Within 27 weeks post treatment
Percentage of patients with hematological response, including complete response (CR) or partial response (PR). Hematological response is evaluated by hemoglobin (Hb), platelet count (PLT) and absolute neutrophil count (ANC).
次要结局
- Overall response rate(Within 3 months post treatment)
- Time to hematological response(Within 27 weeks post treatment)
- Incidence of adverse events(Within 27 weeks post treatment)
