研究目的:

研究主要目的是评价减低剂量地西他滨(DEC)联合维奈克拉(VEN)治疗新诊断的HR-MDS患者的总体反应率(ORR)[总体反应率(ORR)=完全缓解/等效的完全缓解(CR or CR equivalent)+部分缓解(PR)+完全缓解伴不完全血细胞计数恢复(CRL)+完全缓解伴部分血液学恢复(CRh)+血液学改善(HI)]。次要疗效指标是评价细胞遗传学反应(包括完全细胞遗传学反应和部分细胞遗传学反应)、二代测序检测基因突变(NGS)评估MRD、患者报告结局(PROs)、至反应时间(TTR)、反应持续时间(DOR)、转化为急性髓性白血病(AML)的时间、造血干细胞移植(HSCT)率、总体生存期(OS)、无事件生存期(EFS)、无进展生存期(PFS)。  

Objectives of Study:

Primary Study Objective: To evaluate the overall response rate (ORR) of low-dose Decitabine (DEC) combined with Venetoclax (VEN) in the treatment of newly diagnosed high-risk myelodysplastic syndrome (HR-MDS) patients [Overall response rate (ORR) = complete response/equivalent complete response (CR or CR equivalent) + partial response (PR) + CR with limited count recovery(CRL) + complete response with partial hematologic recovery (CRh) + hematologic improvement (HI)]. Secondary Study Objective: To evaluate cytogenetic response (including complete cytogenetic response and partial cytogenetic response), MRD as assessed by second-generation sequencing to detect mutations (NGS), patient-reported outcomes (PROs), time to response (TTR), duration of response (DOR), time to transformation to acute myeloid leukemia (AML), hematopoietic stem cell transplantation (HSCT) rate, overall survival (OS), event-free survival (EFS), progression-free survival (PFS).

干预措施:

地西他滨(DEC):3 天给药方案:20mg/(m^2·次),静脉滴注,每天一次,连续 3 天; 维奈克拉(VEN):400mg/次,口服,每日一次,连续 7 天,每 28 天左右为一个疗程。 如果受试者出现明显毒性反应,则延迟用药、减低剂量给药或停药。为了使患者最大可能的出现缓解,建议受试者至少接受 2 个疗程的治疗

干预措施代码:

Intervention:

Decitabine (DEC): 3-day regimen: 20 mg/(m2 per dose), administered by intravenous infusion once daily for 3 consecutive days; Venetoclax (VEN): 400 mg per dose, taken orally once daily for 7 consecutive days, with one treatment cycle approximately every 28 days. If the subject experiences significant toxicity, dosing should be delayed, reduced, or discontinued. To maximize the likelihood of achieving a response, subjects are recommended to receive at least two treatment cycles.
