Prophylactic Intervention for Relapse Prevention Post-Allogeneic Transplantation in Very High-Risk MDS Patients Based on IPSS-M Stratification
Sponsor: Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine
Summary
By collecting interventional clinical data to assess the survival and relapse conditions of patients post-transplantation and comparing them with historical data, the primary study endpoint is the 1-year and 2-year relapse-free survival (RFS) post-transplantation. This includes the time from the start of treatment until the documentation of disease progression (bone marrow smear blast cells \> 5% or extramedullary relapse) or death due to any cause, whichever occurs first. This experiment aims to improve the post-transplant survival rates of MDS patients classified as very high risk under the IPSS-M stratification and to explore pathways to prevent relapse.

Prophylactic Intervention for Relapse Prevention Post-Allogeneic Transplantation
1.1 AZA + BCL2 Inhibitor (Preferred Regimen) Subcutaneous injection of azacitidine at 32 mg/m² per day for 5 consecutive days, with a 28-day cycle; BCL2 inhibitor (VEN): 400 mg per day orally for one week (if combined with a CYP450 inhibitor, reduce to 100 mg per day). 1.2 AZA (DEC) + DLI For patients with TP53 mutations or those who do not respond to VEN, subcutaneous injection of azacitidine at 32 mg/m² per day for 5 consecutive days, with a 28-day cycle; decitabine at 5 mg/m² per day for 5 consecutive days, with a 28-day cycle (preferred for those with TP53 mutations). For patients without the option for DLI, regimen 1.1 is recommended. DLI: Begins 3 months post-transplantation, starting with a dose of 1×10\^5 CD3+ T lymphocytes for haploidentical transplants, with doses increasing every 4-6 weeks to 5×10\^5 CD3+ T lymphocytes, 1×10\^6 CD3+, and 5×10\^6 CD3+ T lymphocytes; for full-matched transplants, the starting dose is 5×10\^5 CD3+ T lymphocytes with dose escalations as above to 1×1
