Summary

This study aims to evaluate whether immediate allogeneic hematopoietic stem cell transplantation (HSCT) is non-inferior to HSCT following bridging therapy in patients with higher-risk myelodysplastic syndrome (HR-MDS).

Detailed description

A total of 236 patients will be randomized in a 1:1 ratio into the immediate transplantation group (n=118) and the disease control group (n=118). The study will continue until at least 124 events occur.

Conditions

• Myelodysplastic Syndromes

Interventions

Type	Name	Description
OTHER	Immediate HSCT Group	Patients undergo direct allogeneic HSCT.
OTHER	Bridging Therapy Group	Patients receive one to two cycles of bridging therapy before undergoing allogeneic HSCT. o Bridging Therapy Regimen: Hypomethylating agents (HMA) alone or HMA-based combination chemotherapy, e.g., azacitidine (AZA) 100 mg/day + venetoclax (VEN) 400 mg/day for 7 days. Targeted therapies (e.g., IDH1 inhibitors) will be used for eligible patients.
