Summary

A Single-Arm, Prospective Clinical Study of Venetoclax Combined with Azacitidine Followed by Bridging Transplantation in Patients with High-Risk Myelodysplastic Neoplasms with Increased Blasts 2 (MDS-IB2)

Detailed description

This is a single-center, single-arm, prospective study investigating pre-transplant bridging therapy in patients aged ≥18 years with higher-risk MDS-IB2. The study plans to enroll 46 eligible patients. Participants will receive Venetoclax combined with Azacitidine, administered in 28-day cycles for 1 to 2 cycles. Treatment response will be assessed according to the IWG 2023 HR-MDS response criteria.Patients achieving modified Composite Complete Remission (mCRc: CR or CR-equivalent + CRL + CRh) after Cycle 1 will proceed directly to transplantation. Patients not achieving mCRc will receive a second cycle of therapy. All patients will undergo allogeneic hematopoietic stem cell transplantation (allo-HSCT) within 3 months after completing Cycle 2, regardless of mCRc status. Patients unable to proceed to transplantation will receive standard institutional care and undergo follow-up.
