PHASE2

Inotuzumab Ozogamicin in the Treatment of MRD+ After HSCT of ALL

Sponsor: Sheng-Li Xue, MD

View on ClinicalTrials.gov

Summary

As part of postremission consolidative therapy, the decision to proceed with hematopoietic stem cell transplantation is a recommendable regimen in ALL therapy. However, The recurrence rate is high after transplantation. Minimal Residual Disease (MRD) is an important factor affecting the effect of HSCT. The hematologic recurrence rate of MRD-positive patients with adult ALL is high. MRD- is associated with better prognosis. Therefore, maintaining MRD- after transplantation is necessary for long-term survival. The purpose of this study is to explore the efficacy and safety of Inotuzumab Ozogamicin in the treatment of minimal residual disease recurrence after HSCT of ALL patients.
