Summary

This is a prospective, single-arm clinical study. It aims to evaluate the effectiveness and safety of a conditioning regimen containing thiotepa (in combination with busulfan and fludarabine, with or without ATG) of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with chronic myelomonocytic leukemia (CMML) who have an intermediate-2 or high-risk prognosis.

The main goal is to evaluate 1 year RFS and OS. Other goals include assessing engraftment, overall survival, transplant-related complications, and side effects. A total of 31 participants will be enrolled.
